Although replantation of an amputated extremity has been successfully performed, occasionally the surgeon is forced to amputate in the case of an unsalvageable open fracture. These appendages can theoretically act as an autologous 'bone and tissue bank' for patients if they have reconstructable contralateral injuries. We present a case of an athlete who sustained a Gustilo and Anderson IIIC injury on 1 leg resulting in a below knee amputation. Read More

Despite the high incidence of foot and ankle injuries and their biomechanical importance to more proximal joints, the foot and ankle are some of the most daunting and underemphasized musculoskeletal structures in medical training. This study used musculoskeletal ultrasound to identify a knowledge gap in physical medicine and rehabilitation residents in foot and ankle surface anatomy palpation and to determine whether senior residents had higher examination performance compared with more junior residents. Physical medicine and rehabilitation residents at different levels of training were tested cross-sectionally, and palpation accuracy was compared by class year. Read More

Objective: It has been stated that the distal 1-2 cm of the tibialis posterior tendon (TPT) does not have a tendon sheath but rather a paratenon, and that any fluid seen around this segment on ankle MRI is considered to represent paratendonitis. The prevalence and clinical significance of isolated TPT paratendonitis diagnosed on ankle MRI is unknown. This study aims to correlate the presence of isolated distal segment TPT paratendonitis on ankle MRI, with the presence or absence of medial midfoot pain. Read More

Tibialis posterior (TP) tendon ruptures are common after ankle injuries, degenerative processes, or biomechanical instability. The TP tendon decelerates the subtalar joint pronation and internal rotation of the leg during the contact phase. It also plantarflexes and inverts the foot on the leg during the static phase of gait. Read More
