Background The effect on joint stability of repair of type II superior labrum and biceps anchor lesions is unknown. Hypothesis Increased translations of the glenohumeral joint after a simulated type II lesion will be reduced after the lesion is repaired. Study Design Controlled laboratory study. Methods A robotic/universal force-moment testing system was used to simulate load-and-shift and apprehension tests on eight cadaveric shoulders to determine joint kinematics of the shoulder after venting, creation of a type II lesion, and repair of the lesion. Results At 30° of abduction, anterior translation of the vented joint in response to an anterior load was 18.7 ± 8.5 mm and was significantly increased to 26.2 ± 6.5 mm after simulation of a type II lesion. Repair did not restore anterior translation (23.9 ± 8.6 mm) to that of the vented joint. The inferior translation that also occurred during application of an anterior load was 3.8 ± 4.0 mm in the vented joint and increased significantly to 8.5 ± 5.4 mm with a simulated type II lesion. After repair, the inferior translation decreased significantly to 6.7 ± 5.3 mm. Conclusions Repair of a type II lesion only partially restored glenohumeral translations to that of the vented joint. Clinical Relevance Surgical techniques including improved repair of passive stabilizers injured in the type II lesion should be considered.

Anterior Translation

Background: Shoulder disorders affect up to 67% of the adult population at some point in their lifetime. The shoulder complex ranks third, trailing low back and neck pain, in musculoskeletal disorders for which individuals seek physical rehabilitation. The assessment of shoulder stability is an integral component of the patient examination, as it may assist the clinician in making a diagnosis, measuring improvement or deterioration, and determining functional impairments. Reliable tests and measurements are therefore essential to both the clinician and researcher desiring to objectively monitor disease progression, outcomes, and mobility impairments. Many of the currently used clinical tests for anterior instability are documented based on a dichotomous outcome, thus do not provide a means of quantifying or ranking the degree of anterior translation associated with the instability. The load and shift test has been described in textbooks and research investigations as a method to quantify (rank) anterior shoulder instability and/or translation at the glenohumeral joint. This test is attractive clinically, as it requires no special equipment or space, thus may be utilized in multiple settings and without cost; however, few studies have investigated the interrater reliability of this test. Purpose: The purpose of this investigation was to determine the interrater reliability of the seated load and shift test using a 4-level grading criteria. Method: Two investigators performed the load and shift test on the non-dominant shoulder of 29 asymptomatic female participants in a repeated measures intrasession design. Each investigator was blinded to the results and the order of testing was counterbalanced to minimize potential bias. Results: Results indicated good interrater reliability with an Intraclass Correlation Coefficient (2, 1) (95% CI) = 0.80 (0.61, 0.90). Conclusion: The load and shift test appears to be a reliable clinical test for detecting and quantifying anterior translation of the glenohumeral joint when using the grading criteria outlined in this investigation. Shoulder translation when excessive is associated with shoulder instability, thus this test may prove valuable as a measurement of anterior instability. Recommendations: Future investigations are needed to determine the reliability and validity of this test among a symptomatic population and including a male cohort.

The purpose of this study was to determine whether there are changes in anterior and posterior glenohumeral translation after arthroscopic, nonablative, thermal capsuloplasty with a laser. Two anteriorly and two posteriorly directed loads were sequentially applied to the humerus of nine cadaveric glenohumeral joints, and anterior and posterior translation of the humerus on the glenoid was measured. The glenoid was rigidly fixed, and the glenohumeral joint was positioned simulating 90° of shoulder abduction and 90° of external rotation. Using the holmium:yttrium-aluminum-garnet laser, thermal energy was then applied to the anterior capsuloligamentous structures and anterior and posterior translation measurements were then repeated. The results showed a significant reduction in anterior and posterior translation after laser anterior capsuloplasty. Anterior translation decreased from 10.9 2.0 mm (mean SEM) to 6.4 1.5 mm with the 15-N load; and from 13.4 2.1 mm to 8.9 1.8 mm with the 20-N load. Posterior translation decreased from 7.2 1.2 mm to 4.4 0.6 mm with the 15-N load and from 10.4 1.4 mm to 6.5 0.9 mm with the 20-N load. These results indicate that the holmium:yttrium-aluminum-garnet laser can be used to decrease glenohumeral joint translation and may be an effective treatment for glenohumeral joint instability.
