| Research background: Most of Femoral shaft fractures are cased by accident, accounting for approximately 6% of all fractures, the traditional ways of treatment are with plaster fixation, external fixation, internal fixation and intramedullary nail fixation, and the intramedullary nail fixation has already become the golden standard for the surgical treatment of femoral shaft fracture.There is often a significant shift for femoral shaft fractures because of the function of muscles.With single traction, closed reduction and intramedullary nail fixation, we can regain the line of force of the lower limbs,but the reset is difficult, long operation time is needed, more blood gets lost, even nerve injuryã€hip abductor weaknessã€nonunion happens after operation, which affect the recovery of limb function.Objective: To investigate the clinical effect of locking intramedullary nail fixation with reset of closed reductional device for treatment on femoral shaft fracture.Methods: Retrospectively analysis is used in 100 cases of femoral shaft fracture(Locking intramedullary nail fixation with the reset of closed reductional device are used for treatment in 50 cases, and the other 50 cases just got fixed by Locking intramedullary nail fixation with the assisted of traction bed),the data analysis is used in two groups in operating time, blood loss, repeated needle frequency, fracture healing time, the numbers which needs open reduction on fracture, incidence of complications.Results: 50 cases(Locking intramedullary nail fixation with the reset of closed reductional device) were followed up for 12-18 months, all were healed, and the healing time is 4-8 months, an average of 5.2 months. No infection happened, no varusã€shorten deformity occurred. The excellent rate of hip and knee function is up to 92% according to the evaluation criteria of Harris and HHS. The other group(fixed by Locking intramedullary nail fixation with the assisted of traction bed) were followed up for 12-18 months, one case of nonunion,others all got healed, average time is about 5.2 months, no infection happened, no varusã€shorten deformity occurred. The excellent rate of hip and knee function is up to 88%.The statistical differences exists between two groups in operating time, blood loss, repeated needle frequency and the numbers which needs open reduction on fracture, no significant differences in fracture healing time, incidence of complications and the function of hip and knee.Conclution: For femoral shaft fracture, locking intramedullary nail fixation with reset of closed reductional device is a convenientã€less traumaã€effective and reliable means to treat. |
