Clinical observation of osteotomy and fusion for the treatment of severe rigid equinus deformity / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To explore clinical efficacy of osteotomy and fusion in treating severe rigid equinus deformity.</p><p><b>METHODS</b>From April 2010 to October 2015, 13 patients(16 feet) with severe rigid equinus deformity were treated with osteotomy and fusion by hollow screw, including 6 males and 7 females aged from 39 to 62 years old with an average of(49.6±5.3) years old;the courses of diseases ranged from 5 to 27 years with an average of (9.0±4.8) years. Six patients (9 feet) were treated with osteotomy and fusion for three joints, 4 patients(4 feet) were treated with osteotomy and fusion for four joints, and 3 patients (3 feet) were treated with osteotomy and fusion for tibiotalar and calcaneal-talar joints. All patients manifested as foot pain, heel could not touch floor and walking before operation. Postoperative complications were observed, AOFAS score were applied to evaluate clinical effect.</p><p><b>RESULTS</b>Thirteen patients were followed up from 18 to 24 months with an average of 20 months. Only one patient occurred local skin necrosis after operation and healed by dressing change and anti-infective therapy. All feet obtained fracture healing, the time ranged from 12 to 16 weeks with an average of 13.2 weeks. AOFAS score were improved from 11.85±10.66 before operation to 81.38±3.69 after operation, and had significant difference(=-25.67, <0.05);15 feet good and 1 foot moderate.</p><p><b>CONCLUSIONS</b>Tibiotalar and calcaneal-talar joint fusion, osteotomy and fusion for three and four joints could treat severe rigid equinus deformity according to patients' individual and could obtain satisfied clinical effects.</p>
