Reduction osteotomy for triphalangeal thumb: an 11-year review.

Since 1977 we have operated on 13 of 15 triphalangeal thumbs in nine children (five boys, four girls). Follow-up ranged from 22 to 134 months (mean, 65 months). Total active motion averaged 63 degrees at the interphalangeal joint and 79 degrees at the metacarpophalangeal joint. There was no evidence of instability or laxity of ligaments. Reduction osteotomy was insufficient to shorten grossly long thumbs of two patients, and it was necessary to shorten the metacarpal. Premature closure of the phalangeal physis occurred in two thumbs but did not result in inadequate length; one postoperative pin-tract infection resulted in nonunion that required reoperation. This long-term experience supports reduction osteotomy for triphalangeal thumbs because it addresses the deformities and preserves both motion and stability.     

Operation for chronic dislocation of the radial head in children. Reduction by osteotomy of the ulna

Nine children with chronic post-traumatic dislocation of the head of the radius were treated by an osteotomy of the ulna with over-correction of the angular deformity and with elongation of the bone. Satisfactory results were obtained in eight cases, the only poor outcome following a three-year delay between the initial injury and the reposition. The interosseous membrane of the forearm appeared to be the most important structure in maintaining the corrected position of the radial head.     

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。     

High tibial osteotomy

High tibial osteotomy (HTO) is a widely performed procedure to treat medial knee arthrosis. In general, published studies on HTO report good long-term results with a correct patient selection and a precise surgical technique. The ideal candidate for an HTO is a middle aged patient (60 to 65 years of age), with isolated medial osteoarthritis, with good range of motion and without ligamentous instability. Some issues that need resolution remain; these include the choice between opening and closing wedge tibial osteotomy, the graft selection in opening wedge osteotomies, the type of fixation, the comparison with unicompartmental knee arthroplasty and whether HTO significantly affects a subsequent total joint replacement. Precise indication, preoperative planning, and operative technique selection are essential to achieve good results.     

High tibial osteotomy

High tibial osteotomy is effective for managing a variety of knee conditions, including gonarthrosis with varus or valgus malalignment, osteochondritis dissecans, osteonecrosis, posterolateral instability, and chondral resurfacing. The fundamental goals of the procedure are to unload diseased articular surfaces and to correct angular deformity at the tibiofemoral articulation. Although the clinical success of total knee arthroplasty has resulted in fewer high tibial osteotomies being done during the past decade, the procedure remains useful in appropriately selected patients with unicompartmental knee disease. Renewed interest in high tibial osteotomy has occurred for a number of reasons. These include the prevalence of physiologically young active patients presenting with medial compartment osteoarthritis; the advent of new techniques for performing the procedure (ie, improved instrumentation and fixation plates for medial opening wedge osteotomy, dynamic external fixation for medial opening wedge osteotomy, and improved instrumentation for lateral closing wedge osteotomy); and the need to concomitantly correct malalignment when performing chondral resurfacing procedures (ie, autologous chondrocyte transplantation, mosaicplasty, and microfracture).     

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.
