Journal Title: Scholars Journal of Applied Medical Sciences - Year 2016, Vol 4, Issue 4
Abstract
Abstract: Fracture neck of the Femur remains as an unsolved problem till today and is a common orthopaedic problem in old age group. Various methods of treatment have been employed since ages but without a universally accepted procedure till today. In our study the advantages of cemented and uncemented Bipolar Hemi Arthroplasty (BHA) over the Austin Moors Arthroplasty (AMP) well documented. Our study conducted in Gandhi Hospital Secunderabad from May 2004 to Oct 2007 retrospectively evaluated patient’s records from case files and also called the patients for clinical and radiological follow up. 20 patients with intracapsular fracture neck of the femur were treated with AMP and 20 patients were treated with BMA. In both the catagories sub capital and Trans cervical fractures of the neck of the femur were taken in our study and in both groups 60 - 73 years (average 65.5 years) patients were included. Exclusion criteria are fractures secondary to malignancies, fractures associated with acetabular fractures, shaft femur fractures and fracture dislocations. Clinical and radiological follow up was done for groin and thigh pain, subsidence and loosening of the prosthesis. In results the mean follow up was three years (range six months - three and half years) the Harris Hip Score in AMP is 76.4 (range 74 - 86) and in BHA the HHS 92 (range 80 - 96). According to Hhs grade the final outcome was excellent in 94, good in 86 and fair in less than 76 Hips with BHA, excellent in 85, good in 75 and fair in less than 70 Hips with AMP. Hip and groin pain reported in 2 patients in uncemented BHA and 6 patients in AMP but did not limit activity in both the groups. Subsidence of the prosthesis less then 5mm was seen in 8 cases in AMP and none in BHA. 2 cases of protrusio acetabuli were reported in AMP group. In conclusion the Patients with intracapsular neck of the femur treated by cemented BHA are devoid of groin and thigh pain or subsidence / protrusio acetabuli compared to patients treated with AMP who complained of groin and thigh pain due to protrusio acetabuli or loosening and subsidence of the femoral stem.
