Purpose: To evaluate the association of subscapularis (SSC) injuries with acromiohumeral instability (AHI) in patients with shoulder impingement syndrome with supraspinatus (SSP) tears.
Materials and Methods: Pre-operative shoulder magnetic resonance images of 106 patients with subsequent arthroscopic confirmation of shoulder impingement syndrome were reviewed retrospectively. Patients with SSC injuries were divided into the following 3 groups: 1) those with no injury symbolized to the SSC[0] (n = 38), 2) those with partial injuries to the SSC[1] (n = 41), and 3) those with complete disruption of the SSC[2] (n = 27). AHI was categorized into 5 stages depending on the SSP lesions: partial tear or pretear tendinosis symbolized to the SSP[0] (n = 24) and according to retraction severity of the SSP tendon with complete tear such as SSP[1] (n = 19), SSP[2] (n = 27), SSP[3] (n = 29), and SSP[4] (n = 7). Also, AHI was divided into two groups such as the mild group summed with SSP plus SSP plus SSP and the severe group summed with SSP plus SSP, including 70 patients and 36 patients, respectively.
Results: Twenty-nine patients (63.0%) among 46 patients with SSC[0] and thirty-two patients (78.0%) among 41 patients with SSC[1] were related to mild AHI. Eighteen patients (66.7%) among 27 patients with SSC[2] were associated with severe AHI. The SSC injury groups were statistically significantly associated with AHI (estimate 0.207, standard error 0.057, p < 0.01).
Conclusion: SSC injuries could be related to AHI in patients with shoulder impingement syndrome.
