OBJECTIVE:The purpose of this study is to evaluate the usefulness of external fixation of intertrochanteric fractures in high risk geriatric patients. DESIGN: Prospective clinical study. SETTINGS: Level-1 trauma Centre. PATIENTS: Fifty high risk geriatric patients with intertrochanteric fractures. INTERVENTION: Close reduction and external fixation using AO external fixator. OUTCOME MEASURED: fracture union, time to union, pin tract infection rate, shortening, varus collapse and range of motion at knee. RESULTS: Fifty patients with average age of 68.5 years all high anaesthetic/surgical risk were managed by closed reduction and external fixation. Forty were operated under regional and ten under local anaesthesia. Eight patients died before fracture union and four were lost in follow up after removal of fixator. Remaining thirty eight were in regular follow up for at least six months. Pin tract inflammation was the most common complication while shortening and varus collapse occurred in ten cases. CONCLUSION: external fixation of intertrochanteric fractures is useful in high risk geriatric patients. KEYWORDS: intertrochanteric fractures, external fixation.
INTRODUCTION:Hip fractures are a leading cause of death and disability among the elderly. 1 These fractures include femoral neck and intertrochanteric fractures. Intertrochanteric fractures generally occur as a result of low energy trauma in advanced age, whereas they are caused by high energy trauma in young age. 2 The incidence of intertrochanteric fractures is increasing day by day as is the life expectancy. Life time risk in industrialized countries of intertrochanteric fractures is 6% for men and 18% for women. 3 Thus we have old patients, many of them with co morbidities, having intertrochanteric fractures. Treatment goals in this population include early rehabilitation, restoration of the anatomic alignment of the proximal part of the femur and maintenance of the fracture reduction. 4 Various treatment methods used for intertrochanteric fractures include operative and nonoperative. 5 Historically, non-operative management took one of the two different protocols. In first approach, directed at early mobilization within the limits of the patient discomfort, the patient is allowed out of bed and in chair within a few days of injury. Ambulation was delayed, but the early bed to chair mobilization helped prevent many complications of prolonged recumbence. This approach did not attempt to treat the fracture specifically and accepted the deformity that invariably ensues. The second approach, in contrast, attempted to establish and maintain a reasonable reduction via skeletal traction (Hamilton Russel traction) until fracture union occurred. This technique was prolonged with difficulty in maintaining the reduction; further all the complications of prolonged recumbence like pressure sores, urinary tract infection, deep vein thrombosis, pulmonary embolism, chest infection are there. Operative methods include open reduction and internal fixation by sli...
