Arch Orthop Trauma Surg 2007; 127:859-61. In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis.It is part of the lumbosacral plexus and emerges from the lumbar vertebrae and sacral vertebrae (L4-S4). Reported risk factors for Baxters nerve impingement include advancing age, the presence of a calcaneal spur, plantar fasciitis, underlying mass, vascular enlargement, muscular enlargement (such as in athletes), obesity, and foot hyperpronation3,8,9,20. Symptoms include tingling and numbness in the hands or fingers. The peroneocalcaneus internus (PCI) muscle is a rare muscle located deep to the flexor retinaculum in the posterior compartment of the lower leg (J). The action of the lateral rotators can be understood by crossing the legs to rest an ankle on the knee of the other leg. palpate and percuss the tibial and medial calcaneal nerve. The Latin translation of 'quadriceps' is 'four headed,' as the group, The palmaris brevis muscle lies just underneath the skin. The injection of a fluid medium, such as local anesthetic or saline, with or without corticosteroids, or even 5% dextrose in water, to dissect across structures or fascial planes under continuous ultrasound observation is known as ultrasound-guided hydrodissection .

Sensory information is carried from the calcaneal periosteum, long plantar ligament, and adjacent vessels3,4,6. While this diagnosis has been said to account for up to 20% of heel pain, (AH)and the medial plantar margin of the quadratus plantae muscle (QP). The rectus femoris is a weaker hip flexor when the knee is extended because it is already shortened and thus suffers from active insufficiency; the action will recruit more iliacus, psoas major, tensor fasciae latae, and the remaining hip flexors than it will the rectus femoris. The masseter is the primary muscle that brings your teeth together when youre chewing. [3]:1244, The muscle inserts onto the greater trochanter of the femur[2] (its tendon often unites with the tendons of the superior gemellus, inferior gemellus, and obturator internus muscles prior to insertion). Similar to entrapment neuropathies elsewhere, resultant effects from nerve compression depend on the severity and chronicity of entrapment. The largest and strongest muscle in, The extensor pollicis longus muscle begins at the ulna and the interosseous membrane, a tough fibrous tissue that connects the ulna and the radius in. Typically, the atrophy and fatty infiltration occurs homogeneously within the muscle belly. Muscles of the gluteal and posterior femoral regions seen from the front. calcaneal spur, soft tissue mass, enlarged vessels) and associated pathology (e.g. Assess for pain with compression of the heel from side to side; and see if performing the. (Medial talar dome osteochondral injury (asterisk) is noted). Symptoms of a tendon tear include swelling, bruising, pain, and weakness. The quadratus plantae muscle (QP) is also indicated. Patients with classic Baxter's nerve entrapment, on the other hand, frequently deny first-step pain while claiming that their symptoms increase with continuous activity. The PCI is bordered anteriorly by the tibia, interosseous ligament, and tibiotalar joint. Our website services, content, and products are for informational purposes only. Some make broad, smooth movements, and others make small, finite movements. MRI has been shown to be extremely valuable in demonstrating muscular changes associated with denervation. The sartorius muscle originates from the anterior superior iliac spine, and part of the notch between the anterior superior iliac spine and anterior inferior iliac spine.It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. If a disease appears to exist but an etiology cannot be determined, you may say, for example, fatigue of unknown etiology. 14 Woods J. Early diagnosis of a nerve compression syndrome may result in reversible damage, whereas late diagnosis nerve compression damage is not typically reversible17. digiti minimi brevis.

There is much confusion in the literature, as there are multiple overlapping classifications and a vast array of descriptive terminology regarding the accessory peroneal muscles. Sagittal T1-weighted (13a) and Coronal proton density-weighted fat-suppressed (13b) images. Symptoms include a sudden sharp pain at the front of the hip or in the groin, swelling and bruising, and an inability to contract the rectus femoris with a full tear. The flexor retinaculum of the hand is a fibrous band that is quite durable and extends over the carpus. 28 Hecker P. Study of the peroneus on the tarsus. When it reaches the lower border of the abductor hallucis, it turns and courses laterally, passing 5.5 mm anterior to the medial calcaneal tuberosity (or spur) and between the quadratus and the underlying flexor brevis until it reaches its distal target of the abductor digiti minimi.[2].

Analysis of release of the first branch of the lateral plantar nerve J Am Podiatr Med Assoc 2000; 90:281-286. There are numerous muscles (Soleus, gastrocnemius, plantaris, abductor digiti minimi, flexor digitorum brevis, extensor digitorum brevis, abductor hallucis, extensor hallucis brevis, quadratus plantae) and the plantar fascia which exert a traction force on the tuberosity and adjacent regions of the calcaneus, especially when excessive or abnormal pronation occurs. These symptoms indicate sub-acute or chronic joint inflammation, especially if they are located over a joint. The muscle begins at the flexor retinaculum in, The movement of the upper arm and shoulder is controlled by a group of four muscles that make up the rotator cuff. The accessory semimembranosus muscle is a rare accessory muscle of the posterior compartment of the thigh.It arises from the distal aspect of the semimembranosus muscle belly and courses through the popliteal fossa between it and the semitendinosus muscle medially and the biceps femoris laterally. The piriformis is a very important landmark in the gluteal region. The peroneocalcaneus internus muscle: MR imaging features. Part 2. The rectus femoris muscle is one of the four quadriceps muscles of the human body.The others are the vastus medialis, the vastus intermedius (deep to the rectus femoris), and the vastus lateralis.All four parts of the quadriceps muscle attach to the patella (knee cap) by the quadriceps tendon.. Axial T2-weighted (1a) and coronal STIR (1b) images. The symptoms should be apparent without regard to exercise. calcaneal apophysitis. It travels distally between the lateral abductor fascia and the medial edge of the quadratus. More testing, including MRIs, X-rays, and nerve conduction tests can be administered to exclude other possible diseases. Symptoms include numbness, weakness, and pain in the hand. An increase in cubic contact of this passage (via a spur or muscle hypertrophy) and/or pronation of the rearfoot/midfoot complex, causing impingement at the nerves sharp turn are both possible predisposing conditions. Because some patients are born without this capacity, make sure to compare the afflicted and contralateral sides. Selective Atrophy of the Abductor Digiti Quinti: An MRI Study. palpate the abductor hallucis origin. calcaneal apophysitis. The posterior tibial (PTT) and flexor digitorum longus (FDL) tendons are also labeled. (Netter's Clinical Anatomy, 2010), Piriformis syndrome occurs when the piriformis irritates the sciatic nerve, which comes into the gluteal region beneath the muscle, causing pain in the buttocks and referred pain along the sciatic nerve. pain with dorsiflexion of toes (MTPJ) places intrinsic muscles on stretch. It is composed of a thin muscle belly and a long thin tendon.While not as thick as the achilles tendon, the plantaris tendon (which tends to be between 3045 centimetres (1218 in) in length) is the longest tendon in the human body. At the distal tibia, the PCI muscle (red) interdigitates with the flexor hallucis longus muscle (blue). Findings suggest the possibility that Botulinum toxin type B may be of potential benefit in the treatment of pain attributed to piriformis syndrome. It lies along the posterior margin of It also attaches to the hamate bones hamulus, which is a curved process that is located on the underside of the hamate bone. These symptoms indicate sub-acute or chronic joint inflammation, especially if they are located over a joint. gastrocnemius-soleus contracture.

All rights reserved. The FDAL is intimately related to the neurovascular bundle and may abut, compress, or impinge upon the posterior tibial and/or lateral plantar nerves (6a). This is a well recognized, but unusual sports injury that can affect young athletes. pulses. 8 Wu KK. It is innervated by the piriformis nerve. The accessory soleus and recurrent tarsal tunnel syndrome: case report of a new surgical approach. Radiologists perform ankle imaging to assess injuries of the foot and ankle anatomy.Experts analyze the different imaging techniques to identify better diseases associated with the foot and ankle, including diabetic foot ulcers and abnormal growths in You have one masseter muscle on each side of your jaw. The first branch of the LPN, Baxters nerve (also known as the inferior calcaneal nerve), originates from the LPN at various levels beneath the deep fascia of the abductor hallucis muscle. Classically, the peronealcalcaneal variant of peroneus quartus is the most common, originating from the peroneus brevis and inserting on the retrotrochlear eminence of the calcaneus (11a,11b). Surgical release of the nerve has been found to be effective in the management of Baxter's nerve entrapment. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. The injury is caused by a forceful movement related to sprinting, jumping, or kicking and is common in sports like football or soccer. Treatment of chronic heel pain by surgical release of the first branch of the lateral plantar nerve. Deep to the flexor retinaculum, this patient's FDAL muscle (arrows) extends posterior to and compresses the neurovascular bundle (yellow). The peroneus quartus (PQ) arises from the peroneus brevis muscle (PB) and courses medial and posterior to the peroneus longus (PL) and peroneus brevis (PB) muscles and tendons before inserting on the retroctrochlear eminence of the calcaneus (asterisk). Inferiorly, it is the same, and the sciatic nerve also travels inferiorly to the piriformis. tense swollen foot. Skeletal Radiology 1999;28:130-137. The first patient above (Figures 1a,1b), underwent decompression of the tarsal tunnel in conjunction with Baxters nerve release, completely resolving her lateral foot pain. The muscle is seen posterior to the flexor hallucis longus tendon (FHL). A&A Practice. Functionally, the FDAL is thought to assist in toe flexion. Bells Palsy Symptoms 2. Other origins include the peroneus longus and the posterior surface of the fibula. 33 Best A, Giza E, Linklater J, Fracs M. Posterior Impingement of the ankle caused by anomalous muscles: a report of four cases. Symptomatic relief has been reported with surgical excision. The piriformis is a flat muscle, and is pyramidal in shape. 2005-2022 Healthline Media a Red Ventures Company. The anterior inferior ligament and the anterior ligament of the lateral malleolus are also known as the anterior tibiotalar ligament. The symptoms should be apparent without regard to exercise. The carpus is a group of bones located in the wrist between the ulna, the radius and the metacarpus. Web. In severe cases, treatment requires surgery to divide the flexor retinaculum. Associated conditions. It is one of the six muscles in the lateral rotator group. Quadratus plantae. It lies deep to the deep aponeurosis and flexor retinaculum, differentiating it from the accessory soleus muscle. Carpel tunnel syndrome may be caused by anything that leads to inflammation in the wrist. In most cases Physiopedia articles are a secondary source and so should not be used as references. Canadian Association of Radiologists 2003;53(5)313-315. Medial view of the ankle with the abductor hallucis partially removed depicting the posterior tibial nerve (PTN) branches. Posteriorly, the PCI is bordered by the soleus, and laterally by the fascia separating the PCI from the peroneal muscles. On the T2-weighted view, edema is noted within the ADM (arrows) and flexor digitorum brevis (arrowheads) muscle bellies compatible with subacute denervation injury. The flexor digitorum longus (FDL) and posterior tibial tendon (PTT) are also labeled. [1] Up to 20% of cases of chronic heel pain are caused by Baxter's nerve entrapment. A calcaneal plantar enthesophyte3,8 and/or soft tissue changes of plantar fasciitis9 may also contribute to entrapment at this second location. MR can be used to detect denervation-related muscle changes in the ADM, confirming the diagnosis of Baxters nerve impingement3,6,8,9,12. Clin Orthop 1997;337:180-186. It lies along the posterior margin of the flexor hallucis longus muscle and tendon (FHL). presence of lies posteromedial to brachial artery in anterior compartment of upper 1/2 arm; pierces medial IM septum at the arcade of Struthers ~ 8cm from medial epicondyle and lies medial to the triceps . Pelvic contents: male.Superior view.Deep dissection. Healthline Media does not provide medical advice, diagnosis, or treatment. The nerve courses vertically between the abductor hallucis and quadratus plantae muscles, then makes a sharp 90 degree horizontal turn, coursing laterally beneath the calcaneus to innervate the ADM muscle3,5,9,15. These muscles, acting via the tendon, cause plantar flexion of the foot at the ankle joint, and (except the soleus) flexion at the knee. Radiology. As the nerve passes between the deep fascia of the abductor hallucis muscle (AH)and the medial plantar margin of the quadratus plantae muscle (QP). Motor innervation supplies the ADM, occasionally to the flexor digitorum brevis and lateral half of the quadratus plantae. The morphology of the long accessorius muscle. Radiographic features The piriformis muscle (from Latin piriformis 'pear-shaped') is a flat, pyramidally-shaped muscle in the gluteal region of the lower limbs.It is one of the six muscles in the lateral rotator group.. Symptoms of a tendon tear include swelling, bruising, pain, and weakness. Associated conditions. Accessory muscles of the ankle are typically asymptomatic, but can cause pain, compressive neuropathy, compartment syndrome, or rigid hindfoot deformities, and can also mimic soft tissue tumors.1-8. flexor digitorum brevis, abductor digiti minimi 2nd layer: quadratus plantae, lumbricals. tender to palpation at medial tuberosity of calcaneus. J Foot Surg 1986;25:296. The plantaris is one of the superficial muscles of the superficial posterior compartment of the leg, one of the fascial compartments of the leg.. Coronal T1 (10a) and coronal proton density-weighted (10b) images of the ankle in a patient with severe atrophy and fatty infiltration selectively involving the ADM due to chronic Baxter's nerve impingement. Clinical Orthopaedics 1975;158. Accessory muscles around the ankle are frequently asymptomatic, but can be associated with pain, a mass, compressive neuropathy, compartment syndrome, or rigid hindfoot deformities. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. Human anatomy is a fascinating and complex subject, and one that is interesting to virtually every one of us. This is due to forceful contraction of the muscle that generates a force greater than that which holds the bone together. Baxter's nerve is vulnerable to entrapment because of its course, and the most common location is the tight fascia of the abductor hallucis and the medial aspect of the quadrates plantae muscle. 13 Schon LC, Glennon TC, Baxter DE. Report of 2 cases. [2][1] In 17% of people, the piriformis muscle is pierced by parts or all of the sciatic nerve. However, this condition is much less common than carpal tunnel syndrome. It passes behind the medial condyle of the femur to end in a tendon. Two sites of entrapment have been described with Baxters nerve impingement. Skeletal Radiol. Radiologists perform ankle imaging to assess injuries of the foot and ankle anatomy.Experts analyze the different imaging techniques to identify better diseases associated with the foot and ankle, including diabetic foot ulcers and abnormal growths in Congenital variations of the peroneus quartus muscle: an anatomic study. 6 Bonnell J, Cruess RL. A sacral plexopathy is a disorder affecting the nerves of the sacral plexus, usually caused by trauma, Accessory muscles are isointense to skeletal muscle on all pulse sequences, and can insert by fleshy muscular or tendinous insertions. Radiol Clin North Am. Similarly, the rectus femoris is not dominant in knee extension when the hip is flexed since it is already shortened and thus suffers from active insufficiency. A report of 4 cases and review of literature. 5 Danielsson LG, el-Haddad I, Sabri T. Clubfoot with supernumerary soleus muscle. These findings are best depicted on non-fat-suppressed T1-weighted images18,19. It is composed of a thin muscle belly and a long thin tendon.While not as thick as the achilles tendon, the plantaris tendon (which tends to be between 3045 centimetres (1218 in) in length) is the longest tendon in the human body. Using Phalen's maneuver can also provoke symptoms in several cases. abductor hallucis, flexor digitorum brevis, and quadratus plantae share the origin on medial calcaneal tubercle and may be inflamed as well. Carpel tunnel syndrome may be caused by anything that leads to inflammation in the wrist. Our website services, content, and products are for informational purposes only.

It may have one or two sacral attachments; or it may be inserted into the capsule of the hip joint. adductor hallucis. Within the distal lower leg, a triangular shaped accessory muscle (red) abuts the adjacent neurovascular bundle (yellow) and lies posterior to the flexor hallucis longus muscle (FHL). While Baxters nerve is usually the first branch of the LPN, variation does exist and the nerve can originate directly from the PTN5,14,16. In addition, potential causes of impingement (e.g. Axial T1 (11a) and Coronal T2 fat-suppressed proton density-weighted (11b) images in a different patient with severe diffuse atrophy and fatty infiltration selectively involving the ADM(arrows) due to chronic Baxter's nerve. abductor hallucis, flexor digitorum brevis, and quadratus plantae share the origin on medial calcaneal tubercle and may be inflamed as well. pain out of proportion to injury. Occasionally the term peroneus quartus has been used to refer to several or even all of the accessory peroneal muscles.2,22,24 The reported prevalence is highly variable because of the vast array of classification systems. If a disease appears to exist but an etiology cannot be determined, you may say, for example, fatigue of unknown etiology. Structure. Variations in the origin of the medial and inferior calcaneal nerves. [citation needed], It exits the pelvis through the greater sciatic foramen[1] superior to the sacrospinous ligament. Philadelphia, PA: Lippincott Williams and Wilkins; 2002: 359. The deep fascia of the abductor hallucis muscle (arrow) is in the process of being released in an act to decompress the lateral plantar nerve and branches. Multiple accessory peroneal muscles have been described throughout the literature, including peroneus tertius, peroneus accessorius, peroneocalcaneus externum, peroneus digiti minimi, and peroneus quartus (PQ) muscles. Weakness of the ADM may be present but is difficult to detect clinically9. Although the accessory soleus resides outside the tarsal tunnel, it has been implicated in tarsal tunnel syndrome, likely related to extrinsic compression. 4 DosRemedios ET, Jolly GP. Because of its close relationship to the flexor hallucis longus tendon, the FDAL has also been associated with flexor hallucis longus tenosynovitis. 15 Brodie JT, Dormans JP, Gregg JR, Davidson RS. Symptoms. loss of two-point discrimination. Muscle edema demonstrates bright T2 signal but is isointense to skeletal muscle on the T1 weighted image. Gadolinium enhancement within muscle will also occur in the acute to subacute phases of denervation18. In severe cases, surgery is required. Master techniques in orthopaedic surgery of the foot and ankle. Accessory soleus muscle simulating a soft tissue tumor of the posteromedial ankle region. It is situated partly within the pelvis against its posterior wall, and partly at the back of the hip joint. While this diagnosis has been said to account for up to 20% of heel pain, (AH)and the medial plantar margin of the quadratus plantae muscle (QP). The symptoms should be apparent without regard to exercise. Within the ankle tarsal tunnel, the posterior tibial nerve (PTN) bifurcates into medial (MPN) and lateral (LPN) plantar nerves. Symptoms include tingling, numbness, and pain in the wrists, hands, and forearm. When refering to evidence in academic writing, you should always try to reference the primary (original) source. Exercise with undeveloped or unbalanced musculature, producing chronic irritation, can be an aggravating factor. pain out of proportion to injury. Corticosteroids can be injected into the piriformis muscle if pain continues. However, it's an often-overlooked source of heel pain. J. Anat. Surg Radiol Anat 2002; 24:18-22. Learning anatomy does not have to be difficult and can actually be enjoyable. [citation needed], The piriformis muscle is innervated by the piriformis nerve. Symptoms include numbness, weakness, and pain in the hand. The plantaris is one of the superficial muscles of the superficial posterior compartment of the leg, one of the fascial compartments of the leg.. inspection. Human anatomy is a fascinating and complex subject, and one that is interesting to virtually every one of us. presence of In essence: the action of extending the knee from a seated position is primarily driven by the vastus lateralis, vastus medialis, and vastus intermedius, and less by the rectus femoris. 29 Sobel M, Levy ME, Bohne WH. pulses. Quadratus plantae. Photo courtesy of Shane York, DPM. deep. It does not have an osseous insertion, instead attaching to the proximal 26 Sarrafian S. Myology: anatomy of the foot and ankle, Vol 2. Physical exam. Journal of Foot Surgery 1991 Sept-Oct; 30(5):470-471. Depending upon the given position of the leg, it acts either as external (lateral) rotator of the thigh or as abductor of the thigh. The most common complaint in the foot and ankle region is heel pain. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone. presence of While this diagnosis has been said to account for up to 20% of heel pain, it is often overlooked relative to other causes of heel pain8,10,11. Multiple accessory, supernumerary, and anomalous muscles have been described in the radiologic, surgical, and anatomic literature. The average age of clinical symptoms onset is lower in the case of calcaneonavicular coalition (8-12 years) than of talocalcaneal (12-16 years) because of earlier ossification of the former 3. Typically, therapists will notice a pronated foot structure during the biomechanical assessment. Other insertions include the peroneal tubercle of the calcaneus, inferior peroneal retinaculum, cuboid (peroneocuboideus), and peroneus longus (peroneoperoneolongus). The signal will travel through the anterior root of L4 and into the anterior rami of the L4 nerve, leaving the spinal cord through the lumbar plexus. clinically, to differentiate baxter's nerve entrapment from other heel pain. The neurons for voluntary thigh contraction originate near the summit of the medial side of the precentral gyrus (the primary motor area of the brain). pain with dorsiflexion of toes (MTPJ) places intrinsic muscles on stretch. An (1a) axial T1-weighted image is provided. [2], The posterior aspect of the muscle lies againt the sacrum. 20 Henricson AS, Westlin NE. The first site is located as the nerve passes between the deep fascia of the abductor hallucis muscle and the medial plantar margin of the quadratus plantae muscle. Symptoms of a fractured collarbone include tenderness, swelling, and an inability to move the arm. [4], Muscles of the gluteal and posterior femoral regions. The lateral rotators also oppose medial rotation by the gluteus medius and gluteus minimus. Quadratus plantae and the four lumbricals These aid in flexion of the digits and the matatarsophalangeal joints which provide a lot of stability The third layer has three muscles: The Achilles tendon or heel cord, also known as the calcaneal tendon, is a tendon at the back of the lower leg, and is the thickest in the human body. Am J Sports Med 2006;34:1159-1163. Baxters nerve is a mixed sensory and motor nerve, providing motor innervation to the abductor digiti minimi (ADM) muscle2,4,5. plantar fasciitis, tendon pathology) may be seen, and alternative differential diagnoses (e.g. Accessory soleus: a clinical perspective and report of three cases. This cut relieves pressure on the median nerve without damaging the hand. 1 Cheung YY, Rosenberg ZS. [2], Baxters nerve also known as inferior calcaneal, is the first branch of the lateral plantar nerve arising within the tarsal tunnel. These symptoms indicate sub-acute or chronic joint inflammation, especially if they are located over a joint. With motor nerve injuries, skeletal muscle will become edematous in the acute to subacute phases. flexor digitorum brevis, abductor digiti minimi 2nd layer: quadratus plantae, lumbricals. Its functions are to flex the thigh at the hip joint and to extend the leg at the knee joint.[1]. The abductor hallucis muscle is pulled plantarly (with the large retractor) exposing the deep fascia of the muscle. After giving off a small medial calcaneal nerve branch (MCN), the PTN bifurcates into the medial (MPN) and lateral (LPN) plantar nerves within the tarsal tunnel. Endoscopic decompression of the first branch of the lateral plantar nerve. No atrophy or fatty infiltration of the muscle is seen. Successful surgical treatments for the symptomatic accessory soleus have included fasciotomy, muscle debulking, tendon release, and accessory muscle excision.15,22. These nerves exit the tarsal tunnel and continue along the plantar aspect of the foot. Sequential axial T2-weighted MR images in a 73 y/o female patient with heel pain, numbness, and a clinical diagnosis of tarsal tunnel syndrome. Seventeen percent of the population has their sciatic nerve coursing through the piriformis muscle. Note the signal intensity of the ADM (arrows) is similar to that of adjacent subcutaneous fat, with no significant edema. The PCI tendon inserts on the medial calcaneus below the sustentaculum tali (red arrow head). lies posteromedial to brachial artery in anterior compartment of upper 1/2 arm; pierces medial IM septum at the arcade of Struthers ~ 8cm from medial epicondyle and lies medial to the triceps . Tenderness above the abductor hallucis origin, which can induce laterally radiating discomfort and/or parathesias. Distally, the PCI tendon (red arrow) is seen lateral to the flexor hallucis longus tendon (blue arrow). [6] A more invasive, but sometimes necessary treatment involves surgical exploration; however, the side effects of the surgery could be much worse than alternative treatments such as physical therapy. The posterior division of the L4 root is the femoral nerve. However, sometimes surgery is required to relieve the pressure. That is usually the journal article where the information was first stated. Foot Ankle 1993; 14:129-135. 11 Lui, TH. 24 Sobel M, Levy ME, Bohne WH. Endoscopic approaches to the surgery11 and radiofrequency ablation techniques22 have also been described. It does not have an osseous insertion, instead attaching to the proximal The anterior surface of the muscle is related to the rectum (especially on the left side of the body), and the sacral plexus. Stephen Offutt DP, Patrick DeHeer DP. If recalcitrant pain exists despite conservative treatment, operative intervention has proven successful1,21,23,24. Symptoms include tingling, numbness, and pain in the wrists, hands, and forearm. Prominently engorged veins were present in the tarsal tunnel (arrows, 13b), extending to the plantar medial aspect of the calcaneus, along the expected course of Baxter's nerve, presumably contributing to Baxter's nerve impingement. Tarsal Tunnel Contents Horners Syndrome Symptoms SPAM: Sunken eyeballs/Symphathetic plexus (cervical) affected, Ptosis, Anhydrosis, Miosis. 2020 Nov 1;14(13):e01339. The rectus femoris is situated in the middle of the front of the thigh; it is fusiform in shape, and its superficial fibers are arranged in a bipenniform manner, the deep fibers running straight (Latin: rectus) down to the deep aponeurosis.
