Identification of peroneal nerve’ s safety zone and its clinical value in treatment of MIPPO for proximal tibia fracture / 局解手术学杂志

ABSTRACT

Objective To define the peroneal nerve’ s safety zone and study its clinical value in treatment of MIPPO for proximal tibia fracture. Methods The peroneal nerve’ s safety zone was defined according to dead body anatomy. Patients with proximal tibia fracture were divided into traditional therapy group ( control group) and peroneal nerve’ s safety zone therapy ( observation group) . The curative effects and complications were compared. Results The peroneal nerve’s safety zone of R1 was (45. 30 ± 1. 55) mm,R2 was (45. 61 ± 1. 40) mm,R3 was(45. 42 ± 1. 62) mm,angle A was(33 ± 2. 1)°,angle B was(97 ± 2. 3)°. The operating time,bleeding volume,hospitalization time and fracture time in observation group were significantly lower than those in the control group,but there was no siginificant difference in post-ther-apy infection,delayed healing and other complications. Conclusion The curative effects according to peroneal nerve’ s safety zone are better than traditional MIPPO in proximal tibia fracture.
