Retrospective analysis of factors influencing the operative result after percutaneous osteosynthesis of intracapsular femoral neck fractures.

A retrospective analysis of 104 patients with an intracapsular femoral neck fracture, treated with closed reduction and internal fixation showed that the Garden classification, the age of the patient and the quality of reduction and fixation are predictors for the final outcome. Fractures with a Garden classification of 1 and 2 have significantly better results than Garden 3 and 4 (P < 0.01). An unsuccessful reduction of the fracture and a poor surgical fixation technique had significant effect on the outcome (P = 0.01 and 0.02, respectively). If internal fixation is considered, the reduction and the technique of fixation should be perfect.
