Posterior malleolar fracture: technique and clinical experience of the posterolateral approach / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To introduce the postero- lateral surgical approach to the posterior malleolar fracture and report its clinical outcomes in 32 cases.</p><p><b>METHODS</b>This study consisted of 32 cases, 22 males and 10 females with the mean age of 48 years (range, 21-63 years), suffering from posterior malleolar fracture. All cases were treated with the posterolateral surgical approach to the ankle. The average follow-up period was 28 months (range, 24-35 months). The clinical outcomes of these cases were evaluated on the basis of the Olerud-Molander Ankle (OMA) score and plain radiographs.</p><p><b>RESULTS</b>All cases showed radiological evidence of bony union at follow-up. The average OMA score was 82 points; 21 cases had excellent scores (90-100 points), 9 good (61-90 points), and 2 fair (31-60 points). The excellent-to-good rate was 93.8%. Although most cases did not show any wound dehiscence or necrosis, one patient had a superficial infection which healed after using antibiotic dressing and one had sural cutaneous nerve injury that underwent spontaneous remission without any treatment after three months. In addition, one presented with mild symptoms of peroneal tendonitis that disappeared after plate removal.</p><p><b>CONCLUSION</b>The posterolateral approach offers an effective technique for fracture reduction and fixation of large posterior malleolar fragments.</p>

Clinical investigation of the minimal invasive osteotomy for the treatment of hallux valgus combined with tailor's bunion / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the clinical effects of the minimal invasive osteotomy treatment for hallux valgus combined with tailor's bunion deformity.</p><p><b>METHODS</b>From May 2007 to May 2009, Forty-nine feet of 32 patients (a mean age of 57 years old) of hallux valgus combined with tailor's bunion deformity were reviewed retrospectively, including 2 males(2 feet) and 30 females (47 feet). All patients were treated by the minimal invasive osteotomy. The axial and lateral films of all feet with loading were taken before and after operation. The hallux abducto valgus angle(HAV),intermetatarsal angle(IM), fourth-fifth intermetatarsal angle (IM 4 to 5), modified fourth-fifth intermetatarsal angle (MIM 4 to 5), Metatarsophalangeal-fifth angle (MPA) and lateral deviation of the fifth matatarsal angle (LDA) were compared before and after operation. Therapeutic effects of all the patients were observed after operation, the item including AFAS score and WEN Jian-min's therapeutic effects standard.</p><p><b>RESULTS</b>The average operating time was 40 minutes. All the patients were followed up,and the duration ranged from 6 to 24 months. The HAV angle, IM angle, IM 4 to 5 angle, MIM 4 to 5 angle,MPA angle and LDA angle significantly decreased after operation. The AFAS score significantly raised after operation. According to the criteria, 33 feet got an excellent result, 15 good and 1 fair.</p><p><b>CONCLUSION</b>The minimal invasive osteotomy treatment for hallux valgus combined with tailor's bunion is effective and safe. This method is mini-trauma,less pain and it can make a very soon rehabilitation. This method has widely clinical value.</p>
