Possible injury to the branches of the peroneal nerve during fibular osteotomies

Conclusions The peroneal nerves and their blood supply are at risk during high tibial osteotomies. Fixation of nerves by fibrous tissues, compression by tendinous arcades of the peroneus longus tendon, and narrow passages for nerves crossing dense fibrous septa are all factors which favor the development of peroneal nerve lesions. Intraoperative soft tissue retraction and pull by retractors may damage nerves and vessels. The muscle branch for the extensor hallucis longus muscle is particularly at risk during the fibular osteotomy since it runs directly on the bone.     

Modified Kalish osteotomy: A simple approach to minimizing proximal dorsal stress risers

Proximal dorsal stress risers are a potential complication to the Kalish osteotomy. The authors describe a modification to this osteotomy that is simple and effective. Since performing the wing-clip modification, there have been no observed stress risers.     

A comparison between the Regnauld arthroplasty and osteotomies of the first ray for the treatment of hallux valgus

This article is a retrospective study comparing the efficacy of Regnauld arthroplasty to first ray osteotomies for the treatment of hallux valgus. One hundred consecutive cases of Regnauld arthroplasties were compared with 100 consecutive first ray osteotomies. One hundred fourty-one patients were available for follow-up, and based on clinical/radiographic examinations, 72 were treated with the osteotomy protocol (group A) and 69 with Regnauld arthroplasty (group B). Age at surgery, clinical symptoms, and preoperative radiologic findings were similar for the 2 groups; there was a preponderance of female patients (90%). The average follow-up was 49 months in group A and 51 months in group B. Clinical evaluation showed in the osteotomy group a more stable correction (79% v 49%), greater pain reduction (measured in a visual analog scale from 0 = pain free to 10 = deep intolerable pain), increased residual articular excursion of the first metatarsophalangeal joint (27 degrees of active dorsiflexion from neutral position v 8 degrees ), and less presence of central metatarsalgia (15% v 34%) (P <.05). The radiographic evaluation expressed more stable correction values in group A for the following parameters: joint preservation, sesamoid position, intermetatarsal angle (7 degrees v 12 degrees ), abduction angle of the hallux (14 degrees v 20 degrees ), and proximal articular set angle (8 degrees v 18 degrees ) (P <.05).

目的　评价Tagawa髋臼旋转截骨术治疗髋臼发育不良的临床效果。方法　采用Tagawa髋臼旋转截骨术治疗髋臼发育不良 ,用Harris评分和测量X线髋臼指数来评估手术的临床效果和髋臼 股骨头解剖关系的变化。结果　Harris评分从术前的平均 ( 80± 7.7)分提高到 ( 95± 1.8)分 ,主要表现为疼痛明显改善。X线显示髋臼CE角、AC角、AHI获得明显改善 ,但HLI没有变化。所有病例没有重大并发症发生。结论　Tagawa髋臼旋转截骨术治疗髋臼发育不良能较好地重建髋臼和股骨头的解剖关系 ,可以明显改善患者髋部疼痛症状 ,延迟髋关节骨关节病的发生     

Rotational acetabular osteotomy for acetabular dysplasia of the hip with a giant acetabular bone cyst: a case report

In acetabular dysplasia of the hip joint accompanied by a giant acetabular bone cyst, rotational acetabular osteotomy may cause serious complications, such as bone necrosis after surgery or fracture of the fragile acetabulum during the operation. In a patient with this condition, we performed a two-stage operation: first, autogenous bone grafting supplemented with hydroxyapatite filling, then rotational acetabular osteotomy (after new bone formation had been assured). Radiographs and CT scans showed favorable fusion of the grafted bone. Some 18 months after the second operation, arthrograms showed no inflow of contrast medium from the articular cavity into the bone cyst region, although this had been observed before treatment. Thus, an effective remodeling of bony congruency was indicated in the mobile acetabulum 5 years after the second operation. This two-stage operation appears to be useful for correcting acetabular dysplasia accompanied by a giant bone cyst and to carry a reduced risk of serious complications, such as deterioration of the articular surface of the acetabulum or necrosis of the translocated acetabulum.     

Metatarsal and phalangeal double osteotomy of the first shaft in the treatment of hallux valgus

Numerous surgical techniques have been proposed for the surgical treatment of hallux valgus. Some of them only concern soft tissues; others combine a surgery on the soft tissues with a procedure on the bone structures. The technique we present combines a basimetatarsal valgization by subtractive external osteotomy with a wide metatarso-phalangeal freeing. The basimetatarsal osteotomy allows to correct the deformities in the three planes of space. The basi phalangeal osteotomy is not systematic but is proposed in case of severe hallux valgus, superior to 45° or in case of hallomegalia (gigantism of hallux).     

下颌角截骨术与下颌角外板矢状劈开术联合矫治低角型下颌角肥大

目的：下颌角肥大有多种式术可选,对于低角型下颌角肥大,往往一种式术很难达到满意的矫治效果,本文选择了一组低角型下颌角肥大患者,来研究下颌角截骨术与下颌角外板矢状劈开术联合应用治疗低角型下颌角肥大的治疗效果。方法：选择本科室2005年8月～2005年11月间治疗的24例低角型下颌角肥大患者,完善术前检查与分析。在全麻下应用下颌角截骨术与下颌角外板矢状劈开术进行联合矫治。术后观察治疗效果,并在8周后对所有患者进行随访,调查患者满意度。结果：所有24例患者矫治后Ⅰ期愈合,所有患者下颌角角度增大,两下颌角间宽度明显减小,达到了下颌角的正常美学标准。8周后随访,所有患者均对治疗效果表示满意。结论：下颌角截骨术与下颌角外板矢状劈开术联合应用,可有效地矫治低角型下颌角肥大,使患者下颌角达到一个理想的美学标准。
