Table 2 the ROM deficit of PIPJa 6 months after the operation

From: Treatment of the fresh central slip avulsion of the extensor tendon by bone tunnel-tendon suture: a prospective cohort study

Group Open Closed t P
The extension deficit(°) 12.1±4.0 12.7±1.3 0.562 0.580
The flexion deficit(°) 14.9±3.0 15.5±2.2 0.605 0.552
  1. aROM Range of motion, PIPJ Proximal interphalangeal joint; the ROM deficit = the unaffected side – the affected side. The ROM deficit is represented as mean±standard deviation. Two independent sample T-test is used and P < 0.05 is considered significantly different
