Abstract

The sagittal bands are structurally important, aiding in the central alignment of the extensor tendons over the heads of each metacarpal. They resist the deviation of the tendon with flexion of the metacarpophalangeal (MCP) joint. Injury to the sagittal band can cause the extensor tendon to lose its alignment leading to pain, tendon subluxation, or dislocation. Generally, if these injuries are recognized and treated within 3 weeks of injury, they will not require surgery. The goal of surgery is to restore the anatomic alignment of the extensor tendon by either direct repair of the sagittal band or reconstruction.

摘要

矢状带结构重要，有助于伸肌腱在每个掌骨头上保持中心对齐。它们在掌指关节（MCP）弯曲时抵抗肌腱的偏离。矢状带损伤可导致伸肌腱失去对齐，导致疼痛、肌腱半脱位或脱位。通常，如果这些损伤在受伤后 3 周内得到识别和治疗，它们将不需要手术。手术的目的是通过直接修复矢状带或重建来恢复伸肌腱的解剖对齐。
