Tendon the Achilles tendon stretches as the ankle joint dorsiflexes. During the last portion of the stride, as the foot plantar-flexes (pointing the toes down), the stored elastic energy is released. Furthermore, because the tendon stretches, the muscle is able to function with less or even no change in length, allowing the muscle to generate greater force. The mechanical properties of the tendon are dependent on the collagen fiber diameter and orientation. The collagen fibrils are parallel to each other and closely packed, but show a wave-like appearance due to planar undulations, or crimps, on a scale of several micrometers. In
Schilling tendon procedure Schilling tendon procedure The Schilling tendon procedure is a temporary surgical procedure developed by the former Boston Red Sox team physician William Morgan, MD to stabilize the peroneus brevis tendon so that it is prevented from anterior displacement during ankle eversion. If the peroneal retinaculum is torn, the peroneal tendons are no longer stabilized. This allows the peroneus brevis tendon to move untethered over the lateral malleolus, creating pain. During pitching mechanics, the snapping of the tendon over the bone is painful and distracting to the pitcher. The procedure involves the placement of three sutures through the skin anterior to
