Research summary
The anatomy of the proximal femur has always been a topic of interest among orthopaedic surgeons. With multiple pathological paediatric and adult disorders the proximal femur is vulnerable to, having knowledge of proximal femoral anatomy would assist in the reduction of risk of complications linked to surgeries undertaken in this region.
Hip arthroplasty surgery has been a very successful treatment option for displaced intracapsular hip fractures It is widely recognized that the restoration of true femoral offset plays an important role in the optimisation of soft-tissue tension, resultant force across the hip, and regaining both gait stability and hip biomechanics. During hip arthroplasty surgery detailed efforts are made to restore these biomechanics to maximise patient satisfaction, implant survival and reduce post-operative complications. It is also recommended that the design and dimensions of the femoral component match closely to the anatomy of the patient’s native femur.
We aim to analyse population variation in proximal femoral anatomy by measuring the femoral neck/shaft angle, femoral neck length and horizontal femoral offset using computer tomography (CT)-based imaging. We will be utilising the information obtained to assist orthopaedic surgeons in pre-operative planning for hip arthroplasty surgery and also like to determine if the Exeter trauma stem implant is the best fit for the Scottish population undergoing hip hemi-arthroplasty surgery.
We will retrospectively collect data from the CT hip/pelvis images of 200 randomly selected patients from the PACS radiology archive. We will only be including patients over the age of 50, excluding patients with trauma to the hip/pelvis and those with pelvic bony malignancy. We will be using descriptive analysis which includes calculating the absolute mean, mode, median and ranges of the measured variables. We will then analyse the relationship between these values with the patients' gender and height.
