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。

Subacromial morphometric assessment of the clavicle hook plate

Background

Clavicle hook plates are an effective plate fixation alternative for distal clavicle fractures and severe acromioclavicular joint dislocations. However, post-operative complications associated with the subacromial portion of the hook include acromial osteolysis and subacromial impingement. We examine and quantify the three-dimensional position of the subacromial portion of the hook plate relative to surrounding acromial and subacromial structures in a series of cadaveric shoulders to determine if hook positioning predisposes the shoulder to these noted post-operative complications.

Materials and methods

Fifteen cadaveric shoulders (seven males, eight females) were implanted with 15- or 18-mm hook plates. Dimensions of the acromion and hook plate were digitised and reconstructed into a three-dimensional model to measure acromion dimensions and distances of the subacromial hook relative to surrounding acromial and subacromial structures.

Results

Inter-specimen dimensions of the acromion were highly variable. Mean acromion width and thickness were greater in males than in females (p = 0.01). The posterior orientation of the subacromial hook varied widely (mean posterior implantation angle = 32.5 ± 20°, range 0-67°). The hook pierced the subacromial bursa in 13/15 specimens, made contact with the belly of the supraspinatus muscle in 9/15 specimens, and had focal contact at the hook tip with the undersurface of the acromion in 9/15 specimens.

Conclusions

The wide range of acromial dimensions leads to a high degree of variability in the positioning of the subacromial hook. The observed frequency of hook contact with surrounding subacromial structures in a static shoulder confirms that the position of the hook portion of the implant can predispose anatomic structures to the post-operative complications of subacromial impingement and bony erosion.

Displaced acromion fracture: A rare injury,case report

IntroductionAcromion fractures are extremely rare. There are no common accepted treatment schemes and fixation methods We aimed to present a case which may contribute to the diagnosis and treatment of acromion fracture in a patient with polytrauma.Presentation of caseAcromion fracture associated with scapula and clavicle fractures was diagnosed in 40 years old patient and treated with open reduction and cannulated screw fixation. The fracture healing was completed without causing subacromial impingement.DiscussionIn patients with polytrauma, diagnosis and treatment of acromion fractures can be delayed or overlooked. In improperly treated acromion fractures; pain, movement restriction, subacromial impingement, rotator cuff injury and symptomatic nonunion can occur.ConclusionWe recommend early surgical treatment for displaced acromion fractures, reduction of subacromial space and disruption of the superior shoulder suspensory complex.
