Abstract

Background: Scapholunate advanced collapse (SLAC) is the most common pattern of wrist arthritis. Sparse data exist regarding the SLAC wrist pattern of arthritis. This study aimed to document the epidemiology of advanced SLAC in terms of patients' sociodemographics and possible association with trauma. Methods: Sixty-one patients with severe SLAC wrist were included. Baseline sociodemographic characteristics were reviewed. To evaluate the relationship to injury, this group of cases was compared with a control group of 61 patients with first carpometacarpal osteoarthritis (CMC OA). The following data were collected for both groups: age, gender, history of traumatic injury, history of manual labor, duration of symptoms, and dominant hand involvement. Pearson chi-square tests for categorical variables and independent samples t test for continuous variables were performed to determine differences between groups. Results: Patients with SLAC wrist were more likely to be male (80.3% vs 31.1%; p<0.001), have a history of a traumatic injury (69.5% vs 25.9%, P < .001), have longer symptom duration (10.3 ± 13.3 vs 3.5 ± 2.5 years, P = .001), be involved in a manual labor job (49.0% vs 20.0%, P = .002), and be younger (53.1 ± 10.4 vs 58.3 ± 9.8; P = .006) compared with patients with CMC OA. There was no difference in dominant hand involvement (49.2% vs 53.3%; P = .571) between the groups. Conclusions: This study identified the characteristics of patients with advanced SLAC wrist. Compared with a control cohort of CMC OA, patients with SLAC wrist were more likely to be male, have a history of a traumatic injury, and be younger.
