ABSTRACT

BACKGROUND: This retrospective cohort study evaluated functional outcome and structural integrity after arthroscopic- or mini-open repair of small- to medium-size rotator cuff tears assessed at long-term follow-up. METHODS: All patients operated between 2001 and 2004 were invited to participate. Functional outcome was measured by Constant-Murley Score, Disability of Arm, Shoulder and Hand and Oxford Shoulder Score. Quality of life was assessed with EuroQol Health 5 Dimension. Patient satisfaction was assessed in terms of pain and overall result. Structural integrity of the rotator cuff repair was determined using ultrasound. RESULTS: Of the eligible 62 patients, 44 patients were available for follow-up. After a mean of 11.3 years, 76% of the patients had good to excellent functional outcome on the Constant-Murley Score (median 82, range 29-95). The majority of patients reported good results on both Disability of Arm, Shoulder and Hand and Oxford Shoulder Score (median Disability of Arm, Shoulder and Hand 5.0, range 1.0-54; median Oxford Shoulder Score 19, range 13-39). The quality of life was also good (mean EuroQol Health 5 Dimension utility score 0.88, standard deviation 0.12). Eighty per cent was satisfied with the overall result. Ultrasound examination revealed structural integrity in 76% of all cases. CONCLUSION: This study shows that functional outcome is good and structural integrity is high for the majority of patients 11.3 years after repair of small- to medium-size rotator cuff lesions.

ABSTRACT

BACKGROUND: Bony lesions after shoulder dislocation reduce the joint contact area and increase the risk of recurrent instability. It is unknown whether the innate relative sizes of the humeral head and glenoid may predispose patients to shoulder instability. This study evaluated whether anterior shoulder instability is associated with a larger innate humeral head/glenoid ratio (IHGR). METHODS: We evaluated CT scans of 40 shoulders with anterior shoulder instability and 48 controls. We measured axial humeral head diameter and glenoid diameter following native contours, discarding any bony lesions, and calculated IHGR by dividing both diameters. Multivariate logistic regression determined whether the IHGR, corrected for age and gender as potential confounders, was associated with anterior shoulder instability. RESULTS: Mean IHGR was 1.48 ± 0.23 in the group with anterior shoulder instability and 1.42 ± 0.20 in the group without anterior shoulder instability. Measurements for axial humeral head and axial glenoid diameters demonstrated excellent intra-rater reliability (ICC range: 0.94-0.95). IHGR was not significantly associated with anterior shoulder instability (OR = 1.105, 95%CI = 0.118-10.339, p = 0.930). DISCUSSION: The innate ratio of humeral head and glenoid diameters was not significantly associated with anterior shoulder instability in this retrospective sample of 88 shoulder CT scans.
