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

Table 2 the ROM deficit of PIPJ^a 6 months after the operation

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

^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
