TI  - Classification of primary glenohumeral osteoarthritis in a Turkish population
- morphological study
AB  - Aim: This study aimed to investigate the distribution of modified Walch classification groups in a Turkish
patient population. We think that there may be glenoid morphologies that do not fit the modified Walch
classification due to ethnic differences.
Methods: Computed tomography images of 113 patients with primary glenohumeral osteoarthritis (GHOA)
were evaluated. Version angle was measured according to the Friedman method, and classification was made by
two blinded surgeons according to the modified Walch classification. Patients who did not meet the modified
Walch groups were labeled as “Unclassifiable” and were analyzed as the 8th group.
Results: The mean age of the patients was 85.5 ± 7.5 years. Forty-eight patients were male (42.5%). Eighty-two
patients (72.6%) belonged to Walch group A (60 A1 and 22 A2, respectively). The total percentage of group B
was 16.7% (20 patients). Two patients were included in the “Unclassifiable” group. One of the patients had
glenoid convexity due to advanced disease with 1° anteversion. The other patient in this group had anterior
subluxation without underlying pathology.
Conclusion: The distribution of modified Walch groups in the Turkish population may be different from other
populations. Posterior defective glenoid and excessive retroversion may concern less in the Turkish population
with primary GHOA. Our results were obtained limited population and we think that further epidemiologic
studies with larger sample size are needed.
