Medial flexor retinaculum injuries are not uncommon, but medial flexor retinaculum periosteal avulsion injuries are rare. This patient sustained a medial flexor retinaculum tear readily characterized at computed tomography by an associated proximal retinacular avulsion fracture from the posteromedial tibia. Medial flexor retinaculum injury is often also associated with superficial deltoid pathology and/or medial malleolar fracture. An additional significant complication of medial flexor retinaculum tear is anterior dislocation of the tibialis posterior tendon, which heralds a tibialis posterior fibro-osseous tunnel injury.
内侧屈肌支持带损伤并不少见，但内侧屈肌支持带骨膜撕脱伤却很罕见。该患者发生了内侧屈肌支持带撕裂，在计算机断层扫描中很容易表现为伴有胫骨后内侧近端支持带撕脱骨折。内侧屈肌支持带损伤常还与浅层三角韧带病变和/或内踝骨折有关。内侧屈肌支持带撕裂的另一个重要并发症是胫后肌腱向前脱位，这预示着胫后纤维骨隧道损伤。
