锁定加压钢板微创固定治疗肱骨干骨折的初步报告

目的探讨锁定加压钢板(LCP)经肱骨前侧入路微创穿皮固定治疗肱骨干骨折的方法及疗效。方法2004年2月-2005年1月间,使用LCP经肱骨前侧入路微创穿皮固定治疗肱骨干骨折17例,男12例,女5例;年龄18-75岁(平均48岁)。根据AO分型:A型3例,B型10例,C型4例。结果经14-25个月(平均19．1个月)随访,17例患者全部愈合。骨折愈合时间为9-14周(平均11．3周)。末次随访时,肩关节前屈135°-180°(平均174°),后伸20°-40°(平均38°),外展70°-90°(平均87°);肘关节前屈115°-135°(平均133°),后伸-10°-0°(平均-1°);手臂肩残疾问卷表(DASH)评分6-44分(平均11分)。术后3例出现并发症:1例GustiloⅢB型开放性骨折发生浅表感染,经保守治疗后痊愈;1例术后出现一过性桡神经麻痹,3个月后症状完全消退;另有1例出现明显的肩肘关节功能障碍。无继发骨折移位及内固定物失效或断裂。结论LCP经肱骨前侧入路微创穿皮固定治疗肱骨干骨折可以提供稳定的固定,骨折愈合率较高,神经血管结构相对安全;更适合于粉碎性或骨质较差的肱骨干骨折。     

Extacorporeal shock wave therapy unsuccessful for chronic medial epicondylitis

Medial epicondylitis is a chronic noninflammatory condition resulting from mechanical injury. Despite many treatment options, including rest, medications, physiotherapy and operative interventions, the results are too often poor; thus new treatment options are sought. We treated 4 men with chronic epicondylitis (5 affected joints) with extracorporeal shock wave therapy after failed attempts of other treatments. The patients’ complaints were graded with the Nirschl scoring system prior to and six months after therapy. The treatment consisted of three sessions, at 20-day intervals, of 3000 pulses of ultrasonic shock waves from a Piezolith 3000 unit (energy dosage was gradually increased to reach step 10 equaling 0.9 mJ/mm²). At the 6-month follow-up, no patient was pain free. Three cases had slightly lower Nirschl scores than prior to the procedure but the patients rated this difference as insignificant; two cases were unchanged. No complications were observed but all patients rated the procedure as very unpleasant. The well recognized biologic effects of ultrasonographic waves (heat generation, oscillations, cavitation, etc.) that result in functional and structural changes of cellular membranes with sonochemical reactions (acceleration of normal metabolism, oxygenation and reduction in water solutions, polymer degradation, etc.), even if present in our cases, did not result in a noticeable decrease of symptoms, even though we used high energy and more impulses per session. Significant variations in methodology make inconclusive the results of numerous reports on the use of extracorporeal shock waves in epicondylar degenerative problems, although ineffectiveness of such therapy is the conclusion of a review by Haake and colleagues.     

Arthroscopic treatment of lateral epicondylitis: Indication, technique and early results

The purpose of this study is to present the results of the arthroscopic treatment of lateral epicondylitis. Twenty patients with lateral epicondylitis (mean age 42 years) were treated arthroscopically. The average duration of symptoms prior to surgery was 14 months. The arthroscopic joint inspection showed an intact capsule in seven patients (type-I lesion), in eight patients a linear capsule tear (type-II lesion) and in six patients a complete rupture of the capsule (type-III lesion). An associated intraarticular pathology was documented in eight patients. Within an average follow-up period of 1.8 years, local pain and function were documented and analyzed. Subjective pain at rest was reduced from 5.0 to 0.5 points, pain at daily living activities from 6.0 to 1.0 points and pain at athletic activities from 7.3 to 1.2 points in the VAS score. Function increased from 5.2 to an average value of 10.9 (max. 12 points). Patients returned back to work after 3.2 weeks. In conclusion, the arthroscopic release in patients with radial epicondylitis is a reproducible method with a marked postoperative increase in function within a short rehabilitation period.     

Antegrade interlocking nailing of humeral shaft fractures

The results of 39 humeral shaft fractures (37 patients) treated with antegrade locked nailing using a Russell–Taylor nail were reviewed. There were 30 acute fractures, 6 fractures malaligned in a hanging cast or brace, and 3 pathological fractures. Patient age ranged from 26 to 80 years (average, 59.7 years) and average follow-up was 25.7 months (range, 6–48 months). Fracture union was achieved in 92.3% of our cases, while shoulder function was excellent or good in 87.2% of cases. Antegrade locked nailing offers a dependable solution for the treatment of humeral shaft fractures, especially in polytrauma patients and cases of segmental or pathological fractures. Far less satisfactory results were obtained in comminuted fractures of the proximal third in the humerus, especially in osteoporotic patients, and we therefore advocate caution with the use of intramedullary nailing in this type of fracture. Certain technical aspects such as avoiding nailing the fracture in distraction, properly countersinking the tip of the nail, and achieving adequate fixation stability have been found to be of paramount importance to reduce the incidence of delayed union/non-union rate and to obtain better functional results from the shoulder joint.

肩关节外科领域的发展与现状

肩关节外科作为骨科学的一个分支，在国外发达国家发展迅速，但国内至今尚未形成一个成熟的体系，只有少数大医院成立了独立的肩关节外科专科。关节镜技术的发展完善及人工肱骨头置换的应用，使肩关节外科的治疗手段更加多元化，以往那些所谓的禁忌证逐渐都可以进行手术得到解决。本期《中华创伤骨科杂志》介绍了肩关节外科部分的治疗方法与经验，包括肩关节脱位、肩胛骨骨折、肩峰撞击征、肩关节不稳等手术治疗。在不增加患者经济负担的前提下，微创、最佳的肩关节功能恢复是医生及患者的追求与目标。
