Arthroscopic Management of Posterior Instability due to “Floating” Posterior Inferior Glenohumeral Ligament Lesions
نویسندگان
چکیده
The "floating" posterior inferior glenohumeral ligament (floating PIGHL) is an uncommon cause of posterior shoulder instability. This pathologic lesion, defined as detachment of both the origin of the PIGHL (posterior Bankart lesion) and insertion of the of the PIGHL from its humeral head insertion site, often results in significant and persistent shoulder instability symptoms. An effective surgical technique for arthroscopic repair of a floating PIGHL lesion is described and demonstrated.

Combined posterior osseous Bankart lesion and posterior humeral avulsion of the glenohumeral ligaments: a case report and pathoanatomic subtyping of "floating" posterior inferior glenohumeral ligament lesions.
T he pathoanatomy of anterior shoulder dislocations has been well documented. Perthes described an anterior labral lesion as early as 1906, and Bankart wrote his classic article on recurrent anterior dislocations more than seventy years ago. Until recently, much less had been written about posterior shoulder instability; to our knowledge, the first case series was reported by Reeves in 1963. Re...

INTRODUCTION The aim of our study was to compare US, conventional MRI and MR arthrography findings in patients with anterior shoulder instability and with a clinical diagnosis of labral capsular ligamentous complex lesion. At the same time we evaluated the accuracy of MR arthrography in the diagnosis of this lesion. METHODS After approval of the local Ethics Committee, our department's Trauma...

OBJECTIVES We evaluated patients who underwent arthroscopic repair for posttraumatic, recurrent anterior-inferior glenohumeral instability with capsular laxity. METHODS Seventeen patients (4 females, 13 males; mean age 27 years; range 18 to 40 years) were treated with arthroscopic Bankart repair and posterior capsular plication for posttraumatic, recurrent anterior-inferior glenohumeral insta...
متن کاملBiomechanical analysis comparing a traditional superior-inferior arthroscopic rotator interval closure with a novel medial-lateral technique in a cadaveric multidirectional instability model.
BACKGROUND Commonly performed arthroscopic rotator interval closure techniques that imbricate the rotator interval in a superior-inferior direction have been unable to reproduce the stabilizing effects of an open medial-lateral rotator interval imbrication. HYPOTHESIS The medial-lateral rotator interval closure will allow less inferior and posterior glenohumeral translation than the superior-...
