PEREIRA, Sebastián et al. Osteosíntesis con tornillos canulados en fracturas mediales de cadera: Factores pronósticos y resultados en 93 casos. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2014, vol.79, n.1, pp.27-34. ISSN 1852-7434.

Background: Reduction and osteosynthesis with cannulated screws in femoral neck fracture is a valid therapeutic option. Our objective is to identify prognostic factors and risk groups. Methods: We studied retrospectively 93 femoral neck fractures treated with internal fixation with cannulated screw between June 1995 and March 2011 (71 non-displaced and 22 displaced). Results: In 82 of the 93 cases we observed bone consolidation of the fracture. Eleven patients presented complications (5 non-union and 6 avascular necrosis). Consolidation rates were 95.8% and 63.6% in the non-displaced group and the displaced group of fractures. If the displaced fractures presented conminution, consolidation rate was 50% and 71.4% in the group without conminution. The consolidation index was 46.1% with closed reduction and 88% with open reduction. Conclusion: Closed reduction and internal fixation with cannulated screws in non-displaced femoral neck fractures, regardless of the patient’s age, is a successful method. In displaced fractures, on the other hand, necrosis free consolidation is less predictable, so its indication must be evaluated carefully.
