Association of Age-Related Post Injury Frozen Shoulder with Comorbidities and Delayed Management

Objectives: This research seeks to explore the frequency of post-injury frozen shoulder (adhesive capsulitis) across different age groups, identifying variables that may impact its start and development after diverse shoulder injuries. By assessing age-specific frequency and identifying related risk factors, this research attempts to improve clinical care and preventative initiatives. Methodology: Prospective cohort research was done on 150 patients who experienced shoulder injuries, including fractures, dislocations, and rotator cuff tears, between March 2024 and September 2024. Patients were tracked for the development of frozen shoulder, with frequency rates computed across four age groups: under 30, 30-50, 51-70, and above 70. Multivariate logistic regression was used to assess the effect of injury type, treatment delay, and comorbidities on frozen shoulder occurrence. Results: Out of the 150 patients, 29 got frozen shoulder, resulting in an frequency rate of 19.3%. It rose with age: 8% in patients under 30, 12% in the 30-50 group, 24% in the 51- 70 group, and 32% in those over 70 (p < 0.01). Rotator cuff tears were most significantly related with frozen shoulder, with a frequency of 26%, followed by fractures (17%) and dislocations (10%). Patients who received therapy more than six weeks post-injury had a 35% greater chance of developing frozen shoulder (p = 0.02), with concomitant diseases, notably diabetes and thyroid disorders having further boosting risk (OR = 2.1, p = 0.01). Conclusion: The frequency of post-injury frozen shoulder rises with age especially in individuals over 50 years. Injury type and delayed treatment are important risk factors. However, rotator cuff injuries and treatment delays having high predictive values. These data show the necessity of early intervention and tailored rehabilitation for high-risk individuals to prevent frozen shoulder occurrence. Further study should concentrate on improving preventative strategies and optimizing therapy time.
