ObjectiveTo explore the efficacy of continuous pressurized hollow screw fixation in treatment of young and middle-aged patients with significant shift type (Ⅲ, Ⅳ type) femoral neck fracture. MethodsA total of 110 young and middle-aged patients with femoral neck fracture were divided into group A and group B. Fifty-eight cases in group A were treated with continuous pressurized hollow screw fixation, fifty-two cases of group B were treated with hollow screw fixation. The efficacy of the two groups were compared. ResultsPatients were followed up for 19 to 52 months. Healing time of group A was 85-126 d, the average healing time was (102±18) d, fracture nonunion occurred in two patients, femoral head necrosis in four cases; Healing time of group B was 130-176 d, the average healing time was (150±28) d, fracture nonunion occurred in 9 cases, 12 cases with femoral head necrosis. There were no significant difference in the operation time, X-ray exposure time, and the Harris function score at the time of last follow-up between the two groups (P＞0.05); Fracture healing time, concurrent disease incidence of group A were significantly lower than that of group B, the differences were statistically significant (P＜0.05). ConclusionIt has the advantages of low reoperation rate, low fracture nonunion rate and low incidence of bone necrosis using continuous pressurized hollow screw fixation in treatment of femoral neck fracture of young and middle-aged patients.
