【Abstract】 Objective To compare the curative effect between arthroscopic and open retrograde intramedullary interlocking nails in the treatment of femoral supracondylar fracture. Methods A total of 46 patients with femoral supracondylar fracture underwent the treatment by either arthroscopic (19 patients, Group A) or open (27 patients, Group B) retrograde intramedullary interlocking nails. Results The operation time, surgical blood loss and bone union time in the Group A were less than those in the Group B ( t =-4 193, -21 517 and -4 055, respectively; P =0 000). Follow-up for (10 3±3 6) months in the 46 patients revealed the results of therapy were, according to the Kolmert criteria, excellent in 15, good in 3, fair in 1 in the Group A while excellent in 7, good in 14, fair in 4 and poor in 2 in the Group B, without statistically significances between the two groups in the “good” or “excellent” rates (94 7% vs. 77 8%; χ 2 =1 345, P =0 246). Conclusions Use of arthroscopic retrograde intramedullary interlocking nails has advantages of shorter operating time, less blood loss and quicker bone union, benefiting the recovery of knee joint functions.更多还原
