A diagnostic ultrasound can also be used to diagnose FHL injuries, as it shows the muscle in movement and potential areas of impingement. When done correctly, it can also help strengthen the arch muscles. Usually a slip runs to the flexor digitorum and frequently an additional slip runs from the flexor digitorum to the flexor hallucis. Following this healing period, physical therapy begins. activities involving maximal plantar-flexion, in chronic cases nodule formation may lead to triggering, travels between posteromedial/posterolateral tubercles of the talus, crosses dorsal to FDL (at the Knot of Henry), multiple connections exist between the FDL and FHL, distally it stays dorsal to the FDL and neurovascular bundle, inserts on the distal phalanx of the great toe, plantarflexion of the hallux IP and MP joints, great toe locking with active range of motion, crepitus along the posterior medial ankle, pain with resisted flexion of the IP joint, pain with forced plantarflexion of the ankle, fluid around the tendon at level of ankle joint, pain is posterolateral in os trigonum syndrome, release of the FHL from the fibro-osseous tunnel, tenosynovectomy, possible tendinous repair, in athletes when symptoms persist despite rest and nonsurgical management, direct trauma to the FHL tendon in an acute setting, loss of active interphalangeal joint flexion, Posterior Tibial Tendon Insufficiency (PTTI).

Itis unrealistic to expect to regain full strength in eversion equivalent to normal peroneal function, but the procedure can usually stabilize the ankle and foot adequately even without restoring full strength. Gray's Anatomy. A radiograph should be taken to rule out this condition.[4]. The peroneus . The obturator vessels lie between the muscle and the obturator membrane; the anterior branch of the obturator nerve reaches the thigh by passing in front of the muscle, and the posterior branch by piercing it.
