The thrower's shoulder has long been a topic of debate among shoulder specialists. The tremendous forces produced during the throwing motion coupled with the compilation of the pathology encountered in the thrower's shoulder have generated a complex treatment algorithm. Simplifying management options has been challenging and recommendations continue to evolve. Treatment of injuries to the thrower's shoulder most commonly involves addressing partial articular-sided rotator cuff tears. These can be isolated or more commonly associated with tearing of the posterior superior labrum...

Arthroscopic capsulolabral repair during shoulder stabilization surgery requires the use of suture anchors. Several arthroscopic suturing techniques for capsulolabral repair have been described, and each carries very specific advantages and disadvantages with regard to risk, patient satisfaction, and functional outcomes. The purpose of this report is to describe the oblique mattress lasso-loop stitch. This stitch (1) provides strong initial fixation of the labrum, (2) establishes labral height and allows for larger capsular plication if needed, (3) prevents the suture from cutting through the radial fibers of the glenoid labrum, (4) prevents knot migration to the articular side and loosening of the knot, and (5) requires fewer implants and preserves glenoid bone stock by increasing the amount of labrum and capsule that can be reattached to the glenoid with a single-loaded suture anchor...

Traumatic hip fracture-dislocations are associated with chondral and labral pathology as well as loose bodies that can be incarcerated in the hip joint. Incarceration, such as interposed labrum between acetabulum and femoral head that is not readily visualized preoperatively, is a rare but important cause of pain and can potentially be a source for early degeneration and progression to osteoarthritis. We present three cases, arthroscopic surgery of incarcerated acetabular osseo-labral fragment following reduction of traumatic hip fracture-dislocation...

BACKGROUND: Since the importance of an intact labrum for normal hip function has been shown, labral reattachment has become the standard method for open or arthroscopic treatment of hips with femoroacetabular impingement (FAI). However, no long-term clinical results exist evaluating the effect of labral reattachment. A 2-year followup comparing open surgical treatment of FAI with labral resection versus reattachment was previously performed at our clinic. The goal of this study was to report a concise followup of these patients at a minimum of 10 years...

REVIEW
A Dangin, N Tardy, M Wettstein, O May, N Bonin
With the development of conservative hip surgery techniques, new entities such as microinstability have been identified. Microinstability is a painful supra-physiological mobility of the hip. It results from the association of architectural and functional abnormalities impairing joint stability. These risk factors concern hip joint bone architecture or peri-articular soft tissues. Bone abnormalities are identified on hip assessment parameters. Soft tissues also play a key role in the static and dynamic stability of the hip: the joint capsule, labrum, ligamentum teres and adjacent myotendinous structures affect joint coaptation; any abnormality or iatrogenic lesion concerning these structures may constitute a risk factor for microinstability...

Imaging interpretation of the postoperative shoulder is a challenging and difficult task for both the radiologist and the orthopedic surgeon. The increasing number of shoulder rotator cuff, labrum, and biceps tendon repairs performed in the United States also makes this task a frequent occurrence. Whether treatment is surgical or conservative, imaging plays a crucial role in patient care. Many imaging findings can be used to predict prognosis and functional outcomes, ultimately affecting treatment. In addition, evolving surgical techniques alter the normal anatomy and imaging appearance of the shoulder such that accepted findings proved to be pathologic in the preoperative setting cannot be as readily described as pathologic after surgery...
