LIGAMENT INJURIES PROXIMAL INTERPHALANGEAL LIGAMENTS Partial or complete tears of the proximal interphalangeal ligaments are quite common, due to forced angulation of the joint. Mild sprains require no treatment but with more severe injuries the finger should be splinted in extension for 2 or 3 weeks, If the joint is frankly unstable, especially the index and middle which oppose load from the thumb, repair is considered. Occasionally, the bone to which the ligament is attached is avulsed; if the fragment is markedly displaced (and large enough), it should be re-attached. The patient must be warned that the joint is likely to remain swollen and slightly painful for at least 6–12 months. If the instability persists – which is rare – it can be treated by using spare tendon (e.g. palmaris longus) for reconstruction. ---from 《Apley’s System of Orthopaedics and Fractures》 重点词汇整理： frankly /ˈfræŋkli/adv. 坦率地；老实说 palmaris longus掌长肌 百度翻译： 韧带损伤 近端指间韧带损伤 由于关节被迫成角，近端颞下颌韧带部分或完全撕裂是相当常见的。轻度扭伤无需治疗，但伤势较重者，手指应延长用夹板固定2或3周，如果关节明显不稳定，尤其是食指和中指与拇指承受的负荷相反，则应考虑修复。 偶尔，与韧带相连的骨头会撕裂；如果碎片明显错位（足够大），则应重新附着。必须提醒患者，关节可能会持续肿胀和轻微疼痛至少6-12个月。如果不稳定持续存在（这种情况很少见），可以通过使用备用肌腱（如掌长肌）进行重建来治疗。 |
