Osteoporosis is the most common disease of the musculoskeletal system in old age. Therefore, research on osteoporosis risk factors is actively being conducted. However, whether socioeconomic inequality is associated with the prevalence and diagnosis experience of osteoporosis remains largely unexplored. This study aims to investigate whether socioeconomic inequality can be a risk factor for osteoporosis in postmenopausal women. Cross-sectional data of 1,477 postmenopausal women aged over 50 obtained from the Korea National Health and Nutrition Examination Survey V-2 were analyzed. Univariate analyses were performed to calculate the prevalence of osteoporosis and the rate of osteoporosis diagnosis experience according to the risk factor categories. Multivariate logistic regression analysis was performed to identify the independent variables’ associations with osteoporosis prevalence and diagnosis experience. The prevalence of osteoporosis was 34.8%, while the diagnosis experience rate was 22.1%. The higher the age, the higher the probability of osteoporosis presence and diagnosis experience. The lowest household income level was associated with a 1.63 times higher risk of osteoporosis. On the contrary, this factor was not significant for diagnosis experience. These results were similar for the 50–59 and 60–69 age groups. Among postmenopausal women, those who are older and have low socioeconomic levels are at a high risk of developing osteoporosis. Moreover, the lower the socioeconomic level, the lower the awareness of osteoporosis. Therefore, there is a need to develop more proactive preventive measures in postmenopausal women with low socioeconomic levels.

Arthroscopic superior capsular reconstruction (ASCR) has recently been introduced as an alternative treatment for patients with massive irreparable rotator cuff tears. However, the results of ASCR are still limited, and little information about retear after ASCR or subsequent treatment has been reported. To investigate the retear rate of patients who underwent ASCR and to analyze the clinical outcomes of treatments performed for a retear. Case-control study; Level of evidence, 3. This was a retrospective analysis of prospectively collected data from 42 patients (46 shoulders) who underwent ASCR between March 2015 and April 2018. All patients were divided into 2 groups: those with no retear (30 shoulders) and those with retear (16 shoulders). Pre- and postoperative clinical and radiological results were compared between the 2 groups. The retear pattern and treatment outcomes of the retear group were analyzed. The overall incidence of retear was 35% (16/46). No difference was found in preoperative demographic or clinical data between the 2 groups. Preoperative magnetic resonance imaging data showed a significant between-group difference in the preoperative Goutallier grade of the subscapularis (1.5 ± 1.1 in the no-retear group vs 2.5 ± 1.3 in the retear group; P = .016). In the retear group, there were 10 cases of lateral side tears, 3 cases of midsubstance tears, 2 cases of medial side tears, and 1 case of medial and lateral tears. Reoperation was performed in 8 patients who had lateral insertion tear. Overall, clinical scores improved after ASCR in patients with massive irreparable rotator cuff tears. However, 35% (16/46) of the patients showed retear, and lateral side retear occurred in 68% (11/16). The clinical outcome of the patients with preoperative subscapularis atrophy or postoperative lateral side retears was worse, and reoperation was often required. Therefore, it is important that the lateral side be firmly fixed during the ASCR procedure.

Purpose: Total hip arthroplasty (THA) is an available surgical option for failed acetabular fracture, previously managed by open reduction and internal fixation. This study aimed to report the postoperative outcomes of cementless THA in patients with this condition. Materials and Methods: Between November 2000 and September 2016, 25 consecutive cementless THAs for failed internal fixation after acetabular fractures with a minimum follow-up of 2 years were analyzed. The mean age at the time of surgery was 58 years (36–85 years), and the time elapsed between fracture and THA was 70 months (7–213 months). Clinical and radiologic evaluations were performed on all patients. Results: Clinically, the mean Harris hip score at the last follow-up was 88 points. Walking ability recovered to pre-injury status in 92% patients, and activities of daily living recovered in 96% patients. Radiographically, none of the acetabular cups showed evidence of migration and loosening during the mean follow-up of 50 months. All cases showed stable femoral stem fixation at the last follow-up. Dislocation occurred in three cases (12%). Conclusion: Outcomes of cementless THA after failed internal fixation for acetabular fractures were satisfactory. However, a relatively high incidence of postoperative dislocation is still a concern.
