Abstract
Introduction
- Background: The anatomic total shoulder arthroplasty (aTSA) is a prevalent procedure used to reduce pain and restore range of motion in patients with an osteoarthritic shoulder.1-45 Since 2017, over 800,000 people have received an aTSA. Yet to date, no research has been conducted investigating the relationship between osteokinematicsof the post-surgical shoulder to function.
- Purpose: To explore the correlation between osteokinematicmotions in multiple planes to perceived function.
- Hypothesis: Higher peak movement of the shoulder correlates to improved Disabilities of the Arm, Shoulder, and Hand (DASH) scores and improved upper extremity function.
Methods
- Participants: 15 individuals (10 females and 5 males with ages ranging from 68-82, average age of 76) who were at least one year removed from having received an aTSA. 10 domand 5 non-domsurgeries.
- Tests and Measures:
- Participant function via DASH. 0 (best) -100 (worst)
- Osteokinematicmotion of scapulohumeral complex via G4 3D electromagnetic motion capture system.
Analysis
- Spearman’s rho was used to correlate DASH scores to individual scapular and humeral motion.
- Pearson’s correlation was used to correlate scapular and humeral motions.
Results
- DASH median score of 9.50 (min 0.83, max 29.46)
- Significant DASH correlation to IRS (p = 0.008, r = -0.657).
- Several osteokinematicmotions were found to be significantly correlated:
- IRS to IRF (p = 0.001, r = 0.920).
- IRF to URF (p = 0.23, r = 0.582).
Discussion
- The DASH is non-specific side. Therefore, if the surgical shoulder was not their dominant arm, the patient’s perceptions of function may have been skewed.
- Preliminary data has been collected using PSS to improve specificity.
Conclusion
- Improvements in relative scapular external rotation may be effective in improving function in individuals who have undergone an aTSA.
Clinical Relevance
- Clinicians who work with this patient population should consider expanding their interventions beyond the glenohumeral joint.
