改良Dewar法和关节镜下双钮扣钢板固定法治疗肩锁关节脱位的对比分析

目的 比较改良Dewar法和关节镜下双钮扣钢板固定法治疗新鲜Rockwood Ⅲ~Ⅴ型肩锁关节脱位的临床疗效.方法 1997年10月至2009年10月间卫生部北京医院骨科收治的新鲜Rockwood Ⅲ~Ⅴ型肩锁关节脱位患者中,随访到改良Dewar法28例,男20例,女8例,年龄18～68岁,平均随访6.8年;全关节镜下双钮扣钢板固定法24例,男19例,女5例,年龄19～65岁,平均随访1.5年.分别对两组患者术后的影像学结果、临床疗效及并发症进行对比分析.结果 改良Dewar组和双钮扣钢板组的优良率分别为92.8%和95.8%,两组间优良率、VAS(视觉模拟疼痛评分)和UCLA(美国加州大学洛杉矶分校)功能评分差异均无统计学意义.改良Dewar组喙锁韧带异位骨化发生率较关节镜下双钮扣钢板固定组高,分别为25%和8.33%,但差异无统计学意义.改良Dewar组喙锁间距较双钮扣钢板组大,分别为11.96 mm和8.54 mm(P<0.05).结论 关节镜下双钮扣钢板固定法和改良Dewar法均是治疗新鲜Rockwood Ⅲ～Ⅴ型肩锁关节脱位的有效方法,全关节镜下双钮扣钢板固定法与改良Dewar法相比,创伤较小,术后可以更好的维持喙锁关系.

Abstract：

Objective To compare the clinical outcomes of modified Dewar method versus arthroscopic double Endobutton fixation technique for the treatment of acute acromioclavicular joint dislocation (Rockwood types Ⅲ-Ⅴ).Methods All cases with acute acromioclavicular joint dislocation (Rockwood types Ⅲ-Ⅴ) were treated at our department from October 1997 to October 2009.Among them, 28 cases undergoing modified Dewar method were followed up.There were 20 males and 8 females aged 18-68 years old with a mean follow-up period of 6.8 years.And the arthroscopic technique of Endobutton fixation was employed for another 24 cases.There were 19 males and 5 females aged 19-65 years old with a mean follow-up period of 1.5 years.The radiographic findings, clinical outcomes and complications of two groups were compared.Results The good/excellent rate of modified Dewar group and arthroscopic double Endobutton group were 92.8% and 95.8% respectively.There was no significant difference between two groups.No significant difference existed between two groups as to the VAS (visual analogue scale) pain score and UCLA (University of California at Los Angeles) score.The modified Dewar group had a higher rate of ectopic ossification in coracoclavicular ligament than that of the arthroscopic double Endobutton group (25% vs 8.33%).Yet there was no statistical significance.However, the distance between clavicle and coracoid process was larger in the modified Dewar group (11.96 vs 8.54 mm, P<0.05).Conclusion Both modified Dewar method and arthroscopic double Endobutton fixation technique are both efficient therapies for acute acromioclavicular dislocation (Rockwood types Ⅲ-Ⅴ). The former tends to be more invasive while the latter can better maintain the relationship of corocoid process and clavicle.     

Outcome of distal clavicular fracture separations and dislocations in immature skeleton

Background

There are only a few studies with long-term follow-up of distal clavicular injuries in children and their treatment is not clearly defined. The purpose of our study is to suggest a new classification system according to the fracture pattern and the degree of the displacement, to evaluate the long-term follow-up and also to propose an algorithm for treatment.

Methods

We conducted a retrospective study from 1983 to 2008. Seventy-five children and adolescents, age ranging from 3 to 16 years (46 >8 years), were treated in our department. We classified all these injuries into five groups according to the fracture pattern and into subgroups according to the displacement of the bony particles: greenstick fractures as group I, transverse fractures as group II, oblique fractures as group III (IIa and IIIa: undisplaced, IIb and IIIb: displaced), comminuted fractures as group IV and true dislocation of the acromioclavicular joint as group V. Sixty-three patients were treated conservatively, while 12 sustained surgical treatment.

Results

Fifty-nine patients were re-examined after 2-18 years. All the patients included in groups I, IIa and IIIa had no loss in the motion of their shoulder. Seven of the 29 patients in groups IIb, IIIb, IV and V appeared to have minor loss of motion. A constant score was noted in 52 patients and the results were excellent. None of the patients complained of limitations in daily activities, while five patients, who were treated conservatively, complained of visible prominence at the fracture site. One of them had a clavicular duplication, while another patient treated surgically complicated with coracoclavicular synostosis.

Conclusion

The aforementioned proposed classification of these injuries is based on the fracture pattern and is simple, leading to decision making concerning therapy of these injuries. The functional results after a distal clavicle fracture will be excellent, either after conservative or surgical treatment. Older patients (>8 years) from groups IIb, IIIb, IV and V, with greater displacement, could be treated surgically to have better cosmetic results.     

2种方法治疗锁骨远端骨折合并肩锁关节脱位的疗效观察

目的观察锁骨钩钢板与克氏针张力带2种方法治疗锁骨远端骨折合并肩锁关节脱位疗效对比,降低再脱位的发生率。方法抽取我院于2009年3月至2010年3月收治的60例锁骨远端骨折合并肩锁关节脱位患者随机分为2组。实验组30例,全麻下行锁骨钩钢板治疗。对照组30例,行克氏针张力带治疗。术后随访1个月～1年,并对疗效结果进行统计。结果实验组术后显效22例,有效6例,无效2例,总有效率(包括显效和有效)为92.8%优于对照组,差异有统计学意义(P<0.05)。结论早期行锁骨钩钢板治疗肩锁关节全脱位符合生物力学要求,并发症少,复位满意,可有效减少再脱位的发生,是治疗肩锁关节脱位和锁骨远端骨折的重要方法,但应注意正确的锁骨钩钢板固定经验及之后规范的功能康复锻炼。     

锁骨钩钢板内固定术后钢板钩与肩峰匹配性影像学研究

目的通过测量锁骨钩钢板内固定术后患者影像学资料，分析发生肩峰骨侵蚀的原因是否与钢板钩-肩峰匹配度相关。 方法回顾性分析2015年8月1日至2018年8月31日期间在上海市浦东医院骨科就诊的210例患者的影像学资料，210例患者均因肩锁关节脱位或锁骨远端骨折行锁骨钩钢板内固定治疗，其中男110例、女100例；年龄24~76岁，平均（44.60±8.75）岁；肩锁关节脱位70例，锁骨远端骨折140例。测量术后及终末随访患者肩锁关节正位X线片相关数据，按锁骨钩钢板术后是否发生肩峰骨侵蚀，将纳入患者分为3组：无骨侵蚀组（A组）、伴钢板钩移位骨侵蚀组（B组）、不伴移位的骨侵蚀组（C组），分别测量钢板钩-肩峰的匹配度（β），统计分析术后发生肩峰骨侵蚀与钢板钩-肩峰匹配度之间的关系。 结果纳入研究的210例患者术后随访24~64周，平均（32.0±6.5）周。A组患者115例，B组患者54例，C组患者41例。A组匹配度β（3.72±0.48）mm与B组β¹（6.91±0.84）mm比较差异有统计学意义（P<0.05）；A组匹配度β（3.72±0.48）mm与C组β²（5.88±0.65）mm比较差异有统计学意义（P<0.05）；B组匹配度β¹（6.91±0.84）mm与C组β²（5.88±0.65）mm比较差异有统计学意义（P<0.05）。 结论锁骨钩钢板内固定术后是否发生肩峰骨侵蚀与钢板钩-肩峰匹配度β存在明显相关性，钢板钩与肩峰之间的匹配度越好，β值越小，发生肩峰骨侵蚀的可能性更小。     

重视肩锁关节复合体修复以提高不稳定肩锁关节脱位疗效

正肩锁关节脱位作为肩部的常见损伤,随着交通发达和建筑的发展,交通事故和高处坠落使本病有逐年上升趋势。在诊断和分型方面,逐渐趋向统一:通过病史、体格检查、结合影像学检查使诊断得以明确。从早期的3度分类到目前广泛被认可的Rockwood[1]6型分类:1度和2度与Ⅰ型和Ⅱ型相对应;而3度包含了Ⅲ、Ⅳ、Ⅴ、Ⅵ型。在治疗方面:1度和2度即Ⅰ型和Ⅱ型临床上普遍认可通过保守治疗可以获得满意的疗效;而3度中Ⅲ、Ⅳ、Ⅴ、Ⅵ型的治疗:Ⅲ型损伤仍存有争议,而Ⅳ、Ⅴ、Ⅵ型采用手术复位和稳定治     

Acromioclavicular joint arthritis as the first manifestation of Austrian syndrome

Austrian syndrome is a rare condition caused by invasive Streptococcus pneumoniae, comprising a triad of pneumococcal meningitis, endocarditis, and pneumonia. Herein, we report a 59-year-old male patient who presented with fever and tenderness of the right shoulder. Although the initial diagnosis was acromioclavicular joint septic arthritis, the present case showed a reduced level of consciousness, pulmonary infiltrates, cerebral infarcts, and destruction of the mitral valve. This case suggests that acromioclavicular joint arthritis could be an initial presentation of pneumococcal infection inclusive of Austrian syndrome, especially in patients with some risk factors of invasive pneumococcal infections, such as chronic alcoholism.
