Multidirectional instability of the shoulder 2014
The document discusses shoulder instability, detailing various cases of patients with multidirectional instability and the definitions related to the condition. It highlights outcomes of surgical interventions for atraumatic shoulder instability, mentioning a randomized controlled trial to compare the effectiveness of surgical stabilization combined with physiotherapy against physiotherapy alone. The findings suggest that surgical intervention may enhance recovery in patients suffering from capsulolabral damage.

Editor's Notes

- #11 Background: There currently is a wide variation in the definition of multidirectional instability of the shoulder in the literature. The purpose of this study was to determine if these variations influence the distribution of the diagnoses in a cohort of patients with shoulder instability. Methods: A cohort of 168 patients who underwent shoulder surgery for instability of any type was studied. Statistical analysis was performed in two steps. First, the instability of the shoulder in each patient was classified with the use of four existing systems, and the number of patients classified as having multidirectional instability was compared among the classification systems. Second, the definition of multidirectional instability was modified so that the result of laxity testing was the criterion for making the diagnosis, and the changes in the distribution of patients with a diagnosis of multidirectional instability were analyzed. Results: Classification with the four existing systems resulted in significant differences in the number of patients diagnosed as having multidirectional instability, with two (1.2%), seven (4.2%), thirteen (7.7%), and fourteen patients (8.3%) so diagnosed (p < 0.05). Modification of the definition of multidirectional instability so that it was based on laxity testing resulted in a wide variation in the number of patients diagnosed as having multidirectional instability; these numbers ranged from fourteen (8.3%) to 139 (82.7%) (p < 0.05). Conclusions: This study demonstrated that variations in the criteria used for the diagnosis of multidirectional instability significantly affect the distribution of patients with that diagnosis. The use of laxity testing tends to result in an overestimation of the number of patients with this condition. This observation is important because the results of studies may vary if patients with traumatic instability are considered to have multidirectional instability on the basis of laxity testing. Investigators studying patients with multidirectional instability should carefully define the inclusion criteria that they used.
- #12 In thirty-six patients (forty shoulders) with involuntary inferior and multidirectional subluxation and dislocation, there had been failure of standard operations or uncertainty regarding diagnosis or treatment. Clinical evaluation of these patients stressed meticulous psychiatric appraisal, conservative treatment, and repeated examination of the shoulder. All patients were treated by an inferior capsular shift, a procedure in which a flap of the capsule reinforced by overlying tendon is shifted to reduce capsular and ligamentous redundancy on all three sides. This technique offers the advantage of correcting multidirectional instability through one incision without damage to the articular surface. One shoulder began subluxating again within seven months after operation, but there have been no other unsatisfactory results to date. Seventeen shoulders were followed for more than two years.
- #28 As a result suture plication techniques have more widely applied, both open and arthroscopically…..
- #29 The aim of the study was to assess the surgical role in the management of patients with atraumatic instability of the shoulder who remained unstable despite assessment and treatment by specialist shoulder physiotherapy.
- #30 As above Many had previous episodes of physiotherapy elsewhere but all patients were seen pre-op for a mean of 5.4 months by one of 2 specialist shoulder therapists in our unit
- #31 This table shows pre and post op scores with ranges in brackets. Statistically significantly improved scores were noted in the OS, OI and quick DASH scores
