Posterior surface of calcaneus via calcaneal tendon: Tibial nerve (S1, S2) Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris: Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus
Pain often occurs at night, long after the physical exercise which induced it has stopped, and may be aggravated by climbing stairs. Usually, in this case, motor function of the lower leg will not be impaired. This is a key distinction between saphenous nerve neuropathy and lower back radiculopathy.
The calf (pl.: calves; Latin: sura) is the back portion of the lower leg in human anatomy. [1] The muscles within the calf correspond to the posterior compartment of the leg. The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon.
The lower leg is divided into four compartments by the interosseous membrane of the leg, the anterior intermuscular septum, the transverse intermuscular septum and the posterior intermuscular septum. [1] Each compartment contains connective tissue, nerves and blood vessels.
Isolated plantaris muscle strains are rare, and ruptures normally occur in conjunction with injury to other muscles in the posterior compartment of the lower leg. [7] Symptoms of a plantaris muscle rupture may include an audible popping sound in the area during physical activity, swelling, pain in the back of the lower leg, and persistent soreness.
People with tarsal tunnel syndrome have pain in the plantar aspect of the foot mostly at night. Weight bearing increases pain and weakness is found on intrinsic foot muscles with positive Tinel sign at the tunnel. There is no tenderness present on the plantar foot, though this is typically the primary site of complaint.
The posterior cutaneous nerve of the thigh provides sensory innervation to most of [2] the posterior surface of the thigh (upper leg), [2] [1] and the superior [1] part of the posterior surface of the leg (lower leg), [2] [1] as well as (the inferior part of) the gluteal region (via inferior cluneal nerves, derived from anterior rami of S1-S2 ...
The sural nerve (L4-S1) is a cutaneous sensory nerve of the posterolateral calf with cutaneous innervation to the distal one-third of the lower leg. [1] Formation of the sural nerve is the result of either anastomosis of the medial sural cutaneous nerve and the sural communicating nerve, or it may be found as a continuation of the lateral sural cutaneous nerve [2] traveling parallel to the ...
