Interphalangeal joint dislocations of the lesser toes are relatively rare in clinical practice. Most nonreducible interphalangeal joint dislocations occur as a result of rupture or interposition of the plantar plate or of the collateral ligament in the joint space, thus hindering a closed reduction and, in most cases, compelling an open reduction. A post-reduction radiologic exploration is then essential to identify such an entity and proceed consequently. In some cases, such as the one introduced herein, a misdiagnosis, along with an inadequate surgical correction may lead to recurrence of the deformity and, ultimately, to a salvage arthrodesis.
小趾间关节脱位在临床实践中相对少见。大多数不可复位的趾间关节脱位是由于跖板或侧副韧带在关节间隙破裂或嵌入所致，从而妨碍闭合复位，在大多数情况下需要切开复位。复位后进行放射学检查对于识别这种情况并采取相应措施至关重要。在某些情况下，比如本文介绍的这个病例，误诊以及手术矫正不足可能导致畸形复发，最终不得不进行挽救性关节融合术。
