Treatment of unstable trochanteric fractures with Dimon-Hughston osteotomy displacement fixation and acrylic cement

For the management of unstable trochanteric fractures, a new method consisting of Dimon-Hughston medial displacement osteotomy, fixation with a sliding screw sleeve-plate device, with augmentation of the posterior and medial upper femoral cortical defect with acrylic cement, was performed in 84 patients. All patients were allowed full weight bearing on the affected extremity within 1 week of operation. Sixty-five patients were available for follow-up more than 12 months after operation. Complication rates were low and 77 per cent of the patients achieved excellent and good functional results.     

Maxillo-mandibular osteotomy

The authors present their experience of maxillo-mandibular osteotomies performed at the Charles Nicolle Hospital in Tunis. The objective of this paper is to describe the preliminary steps (clinical, radiographic, photographic, modelling, cephalometric) in order to obtain a precise diagnosis of the dysmorphosis. They use Burstone's cephalometric analyses which allow evaluation of the relations between soft tissues which do not correspond to the relations of bony and dental displacement. They also present several clinical cases, the pre-operative steps and, most importantly, Burstone's cephalometric analyses demonstrating that, after osteotomies, the cephalometric values for soft tissues approach normal values. Complete analysis of the naso-maxillary profile may correct the motivation for consultation in some cases. The indication for Lefort I osteotomy is sometimes more appropriate than rhinoplasty. Preoperative orthodontic preparation is often required. Functional rehabilitation is necessary to adapt the orofacial muscles to the new shapes of the dental arch and to prevent recurrence.     

Triplanar trochanteric osteotomy: a modified anterior trochanteric slide osteotomy

Current methods of trochanteric sliding osteotomy typically preserve the lateral aspect of the greater trochanter, the vastus lateralis, the abductors, posterior capsule, and the external rotators. Our modification to this technique includes leaving an anterior vertical ridge of bone that resists the anterior-directed forces acting on the osteotomy. Furthermore, a chevron-shaped osteotomy provides some additional stabilization to the proximally directed pull of the abductors. We believe these modifications improve the intrinsic stability of the osteotomy, theoretically decreasing the rate of nonunion.     

股骨远端外侧开放楔形截骨与内侧闭合楔形截骨治疗膝外翻的疗效比较

目的对比分析股骨远端外侧开放楔形截骨术与内侧闭合楔形截骨术治疗膝关节外翻畸形临床疗效及优缺点。方法笔者自2009-05—2014-06采用股骨远端内翻截骨术+Tomofix股骨远端锁定钢板内固定治疗50例(61膝)膝外翻畸形,分为观察组(采用股骨远端外侧开放楔形截骨术)和对照组(采用内侧闭合楔形截骨术治疗)。比较2组膝关节损伤与骨关节炎评分(KOOS)、主观满意度指数、股胫角度、膝关节活动度、骨折愈合时间、手术并发症等指标,综合评价该手术方法对膝关节外翻畸形的治疗效果。结果 1例失访,其余49例获得平均35.1(24~72)个月随访。所有截骨部位全部获得骨性愈合。组内KOOS评分显示术后膝关节结构和功能均获得显著改善,差异有统计学意义(P0.01),但2组间比较差异无统计学意义(P0.05)。观察组矫正度数(16.15±3.28)°,对照组矫正度数(15.06±3.65)°,2组间比较差异无统计学意义(P0.05)。膝关节活动度、主观满意指数组间和组内比较均无统计学意义(P0.05)。观察组骨折愈合时间比对照组慢,差异有统计学意义(P0.01)。结论股骨远端外侧开放楔形截骨术与内侧闭合楔形截骨术矫正膝关节外翻畸形均可取得较理想的治疗效果,内侧闭合楔形截骨骨折愈合较快,但外侧开放楔形截骨术骨量丢失少、手术操作简单,值得推广应用。     

Double innominate osteotomy

We performed double innominate osteotomy in twenty-five patients with acetabular insufficiency resulting from congenital dislocation of the hip and other lesions. Following iliac (Salter) osteotomy, the second osteotomy was carried out medial to the obturator foramen in the interval between the symphysis pubis and the pubic tubercle. In children more than six years old, adolescents, and adults, addition of the pubic osteotomy increased the amount of acetabular rotation and coverage of the femoral head that could be achieved. An additional benefit was that the femoral head could be shifted medially, decreasing the length of the femoral lever arm. The improvement in center-edge angle in the twenty-five patients averaged 27 degrees, and the acetabular index decreased an average of 19.5 degrees. The center of the head shifted medially an average of 1.5 centimeters. Hip stability was achieved in twenty-three of the patients.     

Pelvic osteotomy retractor

A retractor which displaces soft tissue from bone in deep wounds and improves lighting and instrument manipulation at its tip is described. Its particular advantage in pelvic osteotomy is emphasised.
