ABSTRACT
OBJECTIVE: To determine the frequency of angular malalignment of femur in patients undergoing Intra Medullary nailing for femur shaft fracture by measuring axis on immediate postoperative plain radiographs. METHODS: A cross-sectional study was conducted at the Section of Orthopaedics, Department of Surgery, Aga Khan University Hospital, Karachi from 1st January 2019 till 30th June 2019. All patients between the ages of 15 to 80 years who underwent IM nailing for femur shaft fractures were included. Angulation was measured on immediate post-operative X-ray films and an angle of ≥5° on AP and/or lateral views was defined as malalignment. RESULTS: A total of 65 patients were enrolled in the study with a mean age of 39.9 ± 16.5 years. Majority of the patients,49 (75.4) were males and road traffic accidents were found to be the most common mechanism of injury. Malalignment after surgery was encountered in 6(9.2%) patients. Proximal femur fractures were noted to be significantly associated with malalignment with a p-value of 0.014. CONCLUSIONS: This shows that frequency rate of malalignment after IM nail for femoral shaft fractures in a developing country like Pakistan is comparable to internationally reported literature and proximal femur fracture is a risk factor for malalignment.

Total Hip replacement offers complete resolution of symptoms and restoration of the hip function. The long-term success of hip replacement primarily depends on wear and osteolysis resulting from the bearing surfaces used in hip replacement surgery. Different bearing surfaces have been used in hip replacements, with variable success rates. Traditional combinations include metal on polyethylene, ceramic on polyethylene, and metal on metal articulations. Ceramic on ceramic Bearing couple is a relatively newer combination recommended for younger patients, requiring Total hip Arthroplasty. Ceramics have the lowest wear rate and are showing promising long-term results in international literature. We report the use of this bearing surface for the first time in Pakistan.
