OBJECTIVE: The best treatment for moderately displaced radial head fractures (Mason type II) still remains controversial. In cases of isolated fractures, there is no evidence that a fragment displacement of ≥ 2 mm gives poor results in conservatively treated fractures. PATIENTS AND METHODS: We retrospectively reviewed 52 patients (31M, 21F) affected by an isolated Mason type II fracture, treated with a long arm cast for two weeks between 2008 and 2013. All patients had practiced sports before being injured...

BACKGROUND: Restoration of soft tissue balance for intraoperative posterior instability during anatomic total shoulder arthroplasty (TSA) is particularly difficult. The effectiveness of posterior capsular plication (PCP) in restoring soft tissue balance is largely unknown. The purpose of this study was to report the outcomes, complications, and reoperations of primary TSA in which a PCP was performed to correct excessive intraoperative posterior subluxation. METHODS: Thirty-eight shoulders (37 patients) underwent PCP for intraoperative posterior instability during anatomic TSA...

BACKGROUND: Humeral avulsion of the glenohumeral ligament (HAGL) is an infrequent but significant contributor to shoulder dysfunction, instability, and functional loss. PURPOSE: To prospectively identify patients with HAGL lesions and then conduct retrospective evaluation of the clinical history, examination findings, and surgical outcomes of these patients. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Over a 6-year period (2006-2011), patients with shoulder dysfunction and a HAGL lesion that was confirmed via magnetic resonance arthrogram (MRA) were prospectively evaluated with a minimum 2-year follow-up...

Recurrent anterior shoulder instability following shoulder dislocation has an incidence as high as 68% among the younger population, however its association with coracoid fracture is extremely rare. Majority of coracoid fractures reported earlier have been shown to be associated with seizure disorder. We report a case of displaced coracoid fracture associated with recurrent anterior instability in a patient with no history of seizure disorder and its implications in causation as well as management are discussed...

BACKGROUND: Recognition and proper treatment of glenoid bone loss (GBL) are important for successful management of anterior shoulder instability. Although GBL has been described as the amount of bony loss from the front of the glenoid, there is also a fragment of bone that is usually displaced and often undergoes attrition. Thus, due to attritional bone loss (ABL) of the fragment, insufficient bone is left to fully reconstruct the glenoid. PURPOSE: To (1) evaluate ABL of the glenoid fragment in recurrent anterior shoulder instability and (2) correlate ABL with clinical history, fragment size, and radiographic findings...

Given the increasing use of reverse total shoulder arthroplasty (RTSA), it is important to study the complications associated with this procedure. We conducted a study of the incidence, predisposing factors, and treatment of RTSA dislocations. Using our institutional database, we retrospectively searched for RTSAs performed between September 27, 2010 and December 31, 2013 and identified postoperative dislocations. Four hundred eighty-seven patients underwent 510 RTSAs (393 primary, 117 revision). Fourteen patients had 15 dislocations (5 in primary RTSAs, 10 in revision RTSAs)...

Post-traumatic shoulder instability is a frequent condition in active population, representing one of most disabling pathologies, due to altered balance involving joints. No data are so far available on early ultrastructural osteo-chondral damages, associated with the onset of invalidating pathologies, like osteoarthritis-OA. Biopsies of glenoid articular cartilage and sub-chondral bone were taken from 10 adult patients underwent arthroscopic stabilization. Observations were performed under Transmission Electron Microscopy-TEM in tangential, arcuate and radial layers of the articular cartilage and in the sub-chondral bone...
