Familial congenital bilateral agenesis of the acromion: a radiologically illustrated case report

Summary Familial congenital bilateral acromion absence was found in four members of one family. Only one of them presented with gradually increasing pain in his left shoulder, resembling a shoulder impingement syndrome. The other members did not have any symptoms. This is the first report of familial occurrence of this extremely rare congenital anomaly.

Agénésie familiale bilatérale de l'acromion : une observation illustrée radiologiquement

Résumé L'absence congénitale bilatérale de l'acromion a été observée chez quatre membres d'une même famille. L'un d'eux seulement présentait des douleurs de l'épaule gauche progressivement croissantes ressemblant à un syndrome de blocage de l'épaule. Les autres membres n'avaient aucun symptôme. Il s'agit de la première observation familiale de cette anomalie congénitale extrêmement rare.

     

肩峰形态的CT观测及其与锁骨钩状钢板的匹配性研究

目的 观测肩峰的应用解剖学参数,分析锁骨钩状钢板与肩峰下表面形态的匹配性,为锁骨钩状钢板的临床应用及改进提供参考依据.方法 2009年10月至2010年2月应用西门子螺旋CT对61例国人行双肩薄层扫描并三维重建,男24例,女37例；年龄20～ 83岁,平均45.2岁.测量肩峰的厚度、长度及宽度,观察肩峰下表面的形态；并比较肩峰下表面形态与钩状钢板的匹配性. 结果 肩峰厚度平均为(0.85±0.1 3)cm,男性平均为(0.94±0.12) cm,女性平均为(0.79±0.10) cm,比较差异有统计学意义(t=2.382,P =0.020)；肩峰长度平均为(2.08±0.20) cm,男性平均为(2.09±0.21) cm,女性平均为(2.06±0.18) cm,比较差异无统计学意义(t=1.541,P=0.129)；肩峰宽度平均为(3.81±0.52) cm,男性平均为(4.34±0.32) cm,女性平均为(3.47±0.25)cm,比较差异有统计学意义(t=2.296,P=0.025). 结论 肩峰的形态存在较大的性别差异,表现在肩峰厚度与宽度方面,现有锁骨钩状钢板的深度偏大,且形态与国人肩峰下表面形态匹配性欠佳,有必要根据性别差异改进器械,同时在使用时注意个体化塑形,以提高疗效,减少并发症.

The effectiveness of extracorporeal shockwave treatment in subacromial impingement syndrome and its relation with acromion morphology

Objective

The aim of this study was to evaluate the effectiveness of the extracorporeal shock wave therapy in the subacromial impingement syndrome and its relationship with the acromion morphology.

A little-known cause of painful shoulder: os acromiale

The incidental discovery of an ’os acromiale' might explain some cases of ’painful shoulder': this is what we have observed in three patients. The purpose of our article is to underline the relevance of the axillary roentgenogram of the shoulder for the correct diagnosis of this anomaly. In all patients the radiographic examination was performed using a computed radiography system; moreover we performed a computed tomographic examination of the acromioclavicular portion of the shoulders with three-dimensional reconstructions.

Scapular deformity in obstetric brachial plexus palsy: a new finding

While most obstetric brachial plexus palsy patients recover arm and hand function, the residual nerve weakness leads to muscle imbalances about the shoulder which may cause bony deformities. In this paper we describe abnormalities in the developing scapula and the glenohumeral joint. We introduce a classification for the deformity which we term Scapular Hypoplasia, Elevation and Rotation. Multiple anatomic parameters were measured in bilateral CT images and three-dimensional CT reconstruction of the shoulder girdle of 30 obstetric brachial plexus palsy patients (age range 10 months-10.6 years). The affected scapulae were found to be hypoplastic by an average of 14% while the ratio of the height to the width of the body of scapula (excluding acromion) were not significantly changed, the acromion was significantly elongated by an average of 19%. These parameters as well as subluxation of the humeral head (average 14%) and downward rotation in the scapular plane were found to correlate with the area of scapula visible over the clavicle. This finding provides a classification tool for diagnosis and objective evaluation of the bony deformity and its severity in obstetric brachial plexus palsy patients.     

The acromial morphology and its implication in impingement syndrome: An anatomical study

Introduction

Resection of acromion in case of impingement syndrome is a controversial issue. It is associated with the risk of instability of humeral head. The aim of our study was to determine the morphometry of acromion so that the decision for arthroscopic resection becomes easier in these cases. The morphometry of acromion was also correlated with other parameters of scapula.

The coracoacromial arch: MR evaluation and correlation with rotator cuff pathology

The relative prevalence of various acromial shapes, appearance of the coracoacromial ligament and enthesophytes along the inferior aspect of the acromioclavicular joint in patients with and without rotator cuff tears were evaluated. Of 76 patients with clinical instability and impingement, 31 had a normal rotator cuff and 45 demonstrated a partial or full tear of the supraspinatus tendon at surgery. Results were compared with those from magnetic resonance (MR) scans of 57 asymptomatic volunteers. Of the 45 patients with a supraspinatus tear, 38% (17) had a flat acromial undersurface (type I), 40% (18) had a concave acromial undersurface (type II), 18% (8) had an anteriorly hooked acromion (type III), and 4% (2) had an inferiorly convex acromion (type IV). Among the 31 patients with a normal rotator cuff at surgery and the 57 asymptomatic volunteers, the respective prevalences of the type I acromion were 39% (12) and 44% (25), of type II 48% (15) and 35% (20), type III 3% (1) and 12% (7), and type IV 10% (3) and 9% (5). Shoulders with surgically proven rotator cuff tears showed a tendential association with a type III acromion (8/45) and statistically significant associations with a thickened coracoacromial ligament (17/45) and acromioclavicular enthesophytes (18/45). For the association between inferiorly directed acromioclavicular joint enthesophytes and rotator cuff tears, age appears to be a confounding factor. The type IV acromion, newly classified by this study, does not have a recognizable association with rotator cuff tears. Assessment of the osseous-ligamentous coracoacromial outlet by may prove helpful to the orthopedic surgeon in patients for whom surgical decompression is contemplated.
