A retrospective analysis was done in 62 patients with 101 digits having extensor tendon injury. Quality of outcome and parameters that might influence outcome were evaluated. The majority of patients were treated with conventional static splinting. Sixty percent of all fingers sustained an associated injury (fracture, dislocation, joint capsule or flexor tendon damage). Patients without associated injuries achieved 64% good/excellent results, and total active motion of 212 degrees. This difference was statistically significant (p less than 0.05). Distal zones (1 to 4) had a significantly poorer result than more proximal zones (5 to 8). The percentage of fingers losing flexion was greater than the percentage of fingers losing extension. In addition, the average degree loss of flexion was greater than the average degree loss of extension. This would seem to indicate that loss of flexion may be a more significant complication from extensor tendon injury than previously thought.
对62例患有101条指伸肌腱损伤的患者进行了回顾性分析。评估了治疗结果的质量以及可能影响结果的参数。大多数患者接受了传统的静态夹板固定治疗。所有手指中有60%伴有相关损伤（骨折、脱位、关节囊或屈肌腱损伤）。无相关损伤的患者获得了64%的良好/优秀结果，总主动活动度为212度。这种差异具有统计学意义（p小于0.05）。远端区域（1至4区）的结果明显比近端区域（5至8区）差。失去屈曲的手指百分比大于失去伸直的手指百分比。此外，屈曲的平均度数损失大于伸直的平均度数损失。这似乎表明，屈曲丧失可能是伸肌腱损伤比以前认为的更严重的并发症。
