“…At the same time, gender and hand dominance was not associated with frequency of os acromiale. A systematic review and meta‐analysis of 23 studies revealed a significantly higher frequency in persons of Black ancestry than in persons of White, Native American, and Middle Eastern ancestries, and significantly higher unilateral and bilateral frequencies in those with Black ancestry; there were no significant interactions of Os acromiale frequency with gender and side.…”

“…Only 62 patients (6.2%) revealed an os acromiale in the axillary radiographs, and the average number of tendons involved in the cuff tear was the same (1.4) in patients with and without os acromiale; the average age of patients with and without os acromiale was 55 and 56 years, respectively. This result was similar to the 8% general incidence of os acromiale reported by Yammine. Ouellette et al .…”

“…It is regarded as one of the reasons for rotator cuff tears and shoulder impingement, which is generally asymptomatic and discovered accidentally. This anatomic deformity occurs more frequently in persons of Black ancestry than in persons of White, Native American and Middle Eastern ancestries. Treatment for symptomatic patients is primarily non‐operative, like nonsteroidal anti‐inflammatory drug, physical therapy or corticosteroid injection.…”

Os acromiale is a developmental defect which results from the lack of an osseous union between the ossification centers of the acromion, leading to the fibrocartilaginous tissue connection. The prevalence of os acromiale is 1% to 15%, and is quite common in the African American population. Os acromiale in adults is easily diagnosed by symptoms and X‐ray, particularly on the axillary view; however, the differential diagnosis of adolescents may require MRI or SPECT–CT. Generally, nonoperative therapy for symptomatic os acromiale should be started, including physiotherapy, nonsteroidal anti‐inflammatory drugs, and injections. Surgical treatment is indicated after failed conservative treatment. In symptomatic patients with fixable acromiale, the tension band technique should be used to make the anterior aspect of the acromion elevated from the humerus head. In patients with small fragments which are unsuitable for reattachment, excision might be the best therapeutic option and lead to good outcomes. Whether using internal fixation or resection, the arthroscopic technique results in a better outcome and fewer complications, especially in older patients or athletes with overhead movement, because of the high incidence of shoulder impingement or rotator cuff tears which can be treated concurrently.

Appraising the methodological quality of cadaveric studies: validation of the QUACS scale

et al. 2015

Although systematic reviews are conducted in the field of anatomical research, no instruments exist for the assessment of study quality. Thus, our objective was to develop a valid tool that reliably assesses the methodological quality of observational cadaveric studies. The QUACS scale (QUality Appraisal for Cadaveric Studies) was developed using an expert consensus process. It consists of a 13-item checklist addressing the design, conduct and report of cadaveric dissection studies. To evaluate inter-rater reliability, a blinded investigator obtained an initial pool of 120 observational cadaveric studies. Sixty-eight of them were selected randomly according to sample size calculations. Three independent researchers rated each publication by means of the QUACS scale. The reliability of the total score was estimated using the intraclass correlation coefficient (ICC). To assess agreement among individual items, margin-free kappa values were calculated. For construct validity, two experts (an anatomist and an experienced physician) categorized the quality of 15 randomly selected studies as 'excellent' (4 points), 'moderate to good' (3 points), poor to moderate' (2 points) or 'poor' (1 point). Kendall's tau rank correlation was used to compare the expert ratings with the scores on the QUACS scale. An evaluation of feasibility was carried out during the reliability analysis. All three raters recorded the duration of quality appraisal for each article. Means were used to describe average time exposure. The ICC for the total score was 0.87 (95% confidence interval: 0.82-0.92; P < 0.0001). For individual items, margin-free kappa values ranged between 0.56 and 0.96 with an agreement of 69-97% among the three raters. Kendall's tau B coefficient of the association between expert ratings and the results obtained with the QUACS scale was 0.69 (P < 0.01). Required rating time per article was 5.4 AE 1.6 min. The QUACS scale is highly reliable and exhibits strong construct validity. Thus, it can confidently be applied in assessing the methodological quality of observational dissection studies.

“…1 The overall prevalence of os acromiale is 7%, and it has a higher frequency in persons of black ancestry. 2 The acromial apophysis develops from 4 main ossification centers: (1) the pre-acromion, (2) the meso-acromion, (3) the meta-acromion, and (4) the basi-acromion. 3 The os acromiale represents a failure of fusion between 2 of these apophyses.…”

Arthroscopy Techniques

The surgical technique for the management of a symptomatic os acromiale remains unclear. Several operative techniques have been described including open excision, open reduction-internal fixation (ORIF), arthroscopic acromioplasty or subacromial decompression, and arthroscopic excision. There are 4 types of os acromiale, with the meso-acromion being the most common and difficult to treat. The excision of a pre-acromion arthroscopically or in an open manner usually produces satisfactory results. However, the open excision of a meso-acromion can lead to persistent pain and deltoid weakness and atrophy. The management of a meso-acromial fragment with ORIF can also result in persistent pain and deltoid weakness and atrophy with nonunion of the fragments. The purpose of this article is to describe an alternative surgical technique to open excision or ORIF when presented with a symptomatic meso-acromiale.
