Abstract
OBJECTIVE: The aims were to study the acromion parameters in the population and to assess the extremity or sex variation in the acromion morphology. METHODS: The lateral acromion angle (LAA) and the acromion index (AI) were assessed in a computed tomographic scan database of 250 individuals in the age group of 20 to 49 years. For the analysis of LAA and AI, 286 and 234 shoulders were available, respectively. RESULTS: The LAA was 73.6 ± 6.6 degrees; 73.7 ± 6.9 and 72.5 ± 6.1 degrees for the right and left shoulder, respectively. The AI was 0.755 ± 0.12; 0.82 ± 0.12 and 0.69 ± 0.12 for the left and the right shoulder, respectively. The AI of the right shoulder was significantly different between the 2 sexes (P = 0.04). The difference in the AI and the LAA of the right and left shoulders was significant (P < 0.0001, P = 0.04). CONCLUSIONS: The morphology of the acromion differs between the right and the left shoulders as well as between sexes.
