Abstract:
Objective:To investigate the primary clinical efficacy of Collinear clamp assisted reduction and proximal femoral nail antirotation(PFNA) in the treatment of medial-lateral irreducible intertrochanteric fractures.
Methods:From January 2012 to December 2016, a total of 21 cases of medial-lateral irreducible intertrochanteric fractures of femur who were treated with Collinear clamp assisted reduction and PFNA in Lishui Hospital of Zhejiang University were selected.There were 12 males and 9 females, with a mean age of 76.7 years(ranged 51 to 91). According to Arbeitsge-meinschaft für Osteosynthesefragen/The Association for the Study of Internal Fixation(AO/ASIF) classification, there were 6 cases of type 31-A1 fractures, 11 cases of type 31-A2 fractures, 4 cases of type 31-A3 fractures.All patients were followed and the clinical results and functional rehabilitation were evaluated during perioperative period and after short term followed-up.
Results:The mean operation time was 61.7min(ranged 40-110min). The mean intraoperative blood loss was 131.7mL(ranged 45-450mL). The average hospitalization days was 13.6d(ranged 7-29d). There were no severe complications and exacerbation of coexisting medical disease.All patients were followed up for 10 to 18 months (average 13.3 months) after treatment.The fracture union was obtained in all patients at the final follow-up.No poor healing, failure of internal fixation, cut-out of proximal screws, varus deformity, re-fractures occurred after operation.The clinical results were evaluated according to Harris hip score, 6 cases achieved excellent results, 13 cases were good, 2 cases were fair at last follow-up.The excellent and good rate of the hip joint function was 90.5%.
Conclusion:Surgical treatment of medial-lateral irreducible intertrochanteric fractures with Collinear clamp assisted reduction and PFNA can result in excellent reduction and function.This technique has less injury and faster recovery.However, the long-term effect needs to evaluate by follow-up.
