Role of hemiarthroplasty in intertrochanteric fractures in elderly osteoporotic patients: a case series
Management of intertrochanteric fractures in elderly osteoporotic patients continues to be a challenging problem for orthopedic surgeons. Cutting out of implant from the femoral head and varus malpositioning of fragments is often seen in such cases if early ambulation is allowed. Prolonged bed rest in elderly patients leads to higher risk of complications such as bed sores, pneumonia and deep vein thrombosis not uncommonly leading to fatal pulmonary embolism. The purpose of this case series study was to assess the role of hemiarthroplasty in the treatment of intertrochanteric fractures in elderly patients and study the complications.
Materials and methods
Twenty-five patients were treated at a tertiary care center with hip hemiarthroplasty in intertrochanteric fractures. Mean age of the patients in the study was 77.8 years. Young patients with stable fractures and patients with active infection were excluded from study. Seventy-two percent of patients in the study were osteoporotic and associated comorbidity was present in 18 patients. Preoperative ambulatory status of all patients was noted for comparison. If calcar was deficient, calcar was reconstructed with a cut autograft from the femoral neck.
All Patients were followed for 1 year and evaluated using Modified Harris Hip Score except one patient who expired in postoperative period probably due to embolism. He had poor cardiopulmonary reserve preoperatively and cement was used in this case. Average period of initiation of full weight bearing in the present study was 5.5 days. Excellent/good results were seen in 20 patients (80%). One of the patients, who remained bedridden even after surgery, developed decubitus ulcer on the back and was labeled as failure. This patient expired 9 months after surgery. Dislocation of prosthesis was not seen in any case. One patient had shortening more than 1.5 cm due to sinking of prosthesis.
Although majority of patients with intertrochanteric fractures can be successfully managed with osteosynthesis, older patients with severe osteoporosis and associated comorbidity may benefit from prosthetic replacement. However, large scale studies are required to prove it conclusively.

ABSTRACT: Purpose This study was aimed to explore and report the short term results of primary cementless hip arthroplasty in treatment of unstable intertrochanteric femur fracture in elderlys. Materials and Methods Between March 2009 and Feburary 2012, 35 arthroplasty cases performed by single surgeon and followed up for more than one year were evaluated. They were 21 females and 14 males with mean age of 78 years (range, 71-92 years). Preoperative evaluation was performed by American Society of Anesthesia score. Retrospective evaluation was performed by operative time, transfusion amount, time to operation days, hospital stay and time to full weight bearing. Clinically, ambulatory ability was checked by Parker and Palmer (P&P) score and function of hip was appraised by Harris hip score (HSS). Radiologically, bone healing of fractured trochanteric fragment and presence of subsidence, stress shielding or osteolysis were checked. Results Fracture type was 11 cases of A2.2, 18 cases of A2.3 and 6 cases of A3.3. Femoral stems used were 8 cases of rectangular tapered wedge type and 27 cases of fluted modular distal fixation type. P&P score improved from mean preinjury score of 7.1 to mean postoperative last follow-up score of 6.5. Median HHS at last follow-up was 75. Mean time to full weight bearing was 47 days (24-79 days). Postoperative complications were one case of linear periprosthetic femoral fracture and one case of postoperative dislocation. Conclusion Cementless hip replacement arthroplasty could be a good option for unstable intertrochanteric femoral fracture in elderlys.
