Abstract
IntroductionAim of this study was to investigate the incidence and extent of femoral shortening in non-geriatric patients after internal fixation of femoral neck fractures in relation to the clinical outcome at mid-term follow-up.Materials and methodsReviewing our admission data, we identified non-geriatric patients (18–65 years) with femoral neck fractures treated with either dynamic hip screw or cancellous screws between 2007 and 2015. Patients were then contacted and invited to a follow-up clinical investigation including whole-leg standing X-rays.ResultsA total of 40 patients with a mean age at surgery of 52 ± 9 years returned for the follow-up examination. Overall, 31 patients (77.5%) had undergone a dynamic hip screw fixation, while 9 patients were treated with cancellous screws (22.5%). The median follow-up time was 65.5 months (5.5 years). We observed shortening of the ipsilateral femur neck in the majority of cases (92.5%). Still, functional outcome in the overall study population was excellent with a median Harris Hip Score of 96.ConclusionsFemoral neck shortening is common in non-geriatric patients after internal fixation of femoral neck fractures. Nonetheless, observed excellent functional outcome at mid-term follow-up supports joint-preserving strategies in non-geriatric femoral neck fractures.

The aim of the study was to evaluate the incidence and extent of femoral shortening in relation to the clinical outcome in non-geriatric patients with femoral neck fractures treated with osteosynthesis
We established a database including patient demographics, injury characteristics, fracture type according to the AO/OTA classification, Garden classification and Pauwels classification, type of implant, time of surgery, interval between surgery and trauma, body mass index (BMI), as well as data from clinical and radiographic follow-up
Summary
Aim of this study was to investigate the incidence and extent of femoral shortening in non-geriatric patients after internal fixation of femoral neck fractures in relation to the clinical outcome at mid-term follow-up. Materials and methods Reviewing our admission data, we identified non-geriatric patients (18–65 years) with femoral neck fractures treated with either dynamic hip screw or cancellous screws between 2007 and 2015. Observed excellent functional outcome at mid-term follow-up supports joint-preserving strategies in nongeriatric femoral neck fractures. Due to higher functional demands of young patients compared to geriatric patients, joint preservation with osteosynthesis is the treatment of choice. As standard treatment both cannulated screws as well as the dynamic
