Nghiên cứu một số đặc điểm giải phẫu xương bả vai ở người Việt Nam trưởng thành

The scapula is a complex anatomical structure playing a central role in shoulder joint movement. Precise assessment of its normal anatomical characteristics is crucial for clinical practice, particularly in orthopedic surgery. While conventional methods like X-ray imaging present limitations in providing detailed, three-dimensional information, advanced techniques such as 3D computed tomography (CT) offer superior accuracy for morphological measurements. Existing literature indicates significant variations in scapular anatomy across different populations and ethnic groups. However, comprehensive studies specifically focusing on the morphological characteristics of the scapula in adult Vietnamese individuals are scarce. This study aims to address this gap by precisely defining key anatomical parameters of the adult Vietnamese scapula using 3D CT reconstructions.

This cross-sectional descriptive study aimed to establish baseline morphometric data for the **scapula** in adult Vietnamese individuals using advanced **computed tomography** (CT) imaging. Data were collected from 80 patients (representing 154 scapulae) at Military Hospital 103 between December 2023 and January 2024. Patients underwent chest CT scans, and 3D reconstructions of the scapula were generated to precisely measure key anatomical parameters including scapular length, width, spine length, glenoid cavity height and width, and the scapular neck angle. Statistical comparisons were then performed based on age group, sex, and laterality (right vs. left).
The study revealed average scapular dimensions: mean length of 141.09 mm, width of 111.40 mm, and spine length of 131.23 mm. The glenoid cavity averaged 33.85 mm in height and 26.18 mm in width, with a mean neck angle of 39.94°. Significant age-related differences were observed, with individuals aged 41-60 years demonstrating wider scapulae, while those aged 18-40 years had longer spines and higher glenoid cavities (p<0.01). Furthermore, male subjects exhibited significantly larger measurements across most parameters, including scapular length, spine length, and glenoid dimensions, compared to females (p<0.001). Crucially, no statistically significant differences were found between the right and left scapulae. These findings provide essential normative data on Vietnamese scapular **anatomy**, highlighting variations influenced by age and sex. This detailed morphometric information is invaluable for clinical applications, particularly in surgical planning for scapular fractures, designing custom prosthetic components for shoulder arthroplasty, and guiding treatment strategies for various shoulder pathologies. The results emphasize the importance of population-specific anatomical databases in musculoskeletal medicine.
