The coracoid has been widely used as a graft to reconstruct anterior glenoid bone defects, as described by the Latarjet and Bristow procedures, with successful results. Nevertheless, at the present, there are no studies correlating the size of the coracoid graft and its relation to the glenoid.
To assess the mediolateral (M-L) and anteroposterior (A-P) thickness of the coracoid process as well as the widest anterior-to-posterior glenoid distance (glenoid width) and to analyze the correlation between these measurements, while comparing these with the A-P coracoid process thickness.
Descriptive laboratory study.
Sixty-one unpaired, adult human cadaveric scapulae were evaluated. Three examiners performed 3 independent measurements of the largest M-L thickness of the coracoid process and also the widest anterior-to-posterior distance of the glenoid. The A-P coracoid process thickness was also measured to compare for correlations with M-L coracoid thickness.
The glenoid width was 26.38 ± 2.69 mm (range, 20.03-32.35 mm), and the M-L coracoid thickness was 14.51 ± 1.90 mm (range, 9.60-19.31 mm). Calculating the ratio between the M-L thickness of the coracoid and glenoid width, we observed that the coracoid represented 43% to 70% of the glenoid width (54% on average). The A-P coracoid process thickness was 8.37 ± 0.93 mm (range, 6.61-9.76 mm), representing 31% of the glenoid width on average.
A strong positive and statistically significant relationship between the coracoid process M-L thickness and the anterior-to-posterior glenoid width exists; the coracoid represents, on average, 54% of the glenoid width.
Most cases of glenoid bone loss in recurrent shoulder dislocation can be reconstructed with the coracoid process to re-establish its anatomy.
喙突已被广泛用于重建前盂唇骨缺损，如 Latarjet 和 Bristow 手术所述，效果良好。然而，目前尚无研究关联喙突移植物的大小及其与盂唇的关系。
评估喙突的内外径（M-L）和前后径（A-P）厚度，以及最宽的盂唇前后径（盂唇宽度），并分析这些测量值之间的相关性，同时与 A-P 喙突厚度进行比较。
描述性实验室研究。
评估 61 个未配对的成人尸体肩胛骨。三名检查者对喙突的最大 M-L 厚度和盂唇的最宽前后径进行了 3 次独立测量。还测量了 A-P 喙突厚度，以比较与 M-L 喙突厚度的相关性。
盂唇宽度为 26.38±2.69mm（范围，20.03-32.35mm），M-L 喙突厚度为 14.51±1.90mm（范围，9.60-19.31mm）。计算 M-L 喙突厚度与盂唇宽度的比值，我们发现喙突占盂唇宽度的 43%至 70%（平均 54%）。A-P 喙突厚度为 8.37±0.93mm（范围，6.61-9.76mm），平均占盂唇宽度的 31%。
喙突 M-L 厚度与盂唇前后径之间存在很强的正相关和统计学显著关系；喙突平均占盂唇宽度的 54%。
复发性肩关节脱位的大多数盂唇骨缺损均可通过重建喙突来重建其解剖结构。
