Multicenter StudyEpidemiology of the Frequency, Etiology, Direction, and Severity (FEDS) system for classifying glenohumeral instability.
The purpose of this multicenter epidemiologic study was to determine the distribution of patients within the Frequency, Etiology, Direction, and Severity (FEDS) classification system to determine which categories are of clinical importance. ⋯ There are 16 categories within the FEDS classification that are clinically significant. Solitary, traumatic, anterior dislocation and occasional, traumatic, anterior dislocation were the most frequently observed in our cohort.

Multicenter StudyInfluence of rupture patterns of the medial patellofemoral ligament (MPFL) on the outcome after operative treatment of traumatic patellar dislocation.
Patellar dislocation usually occurs to the lateral side, leading to ruptures of the medial patellofemoral ligament (MPFL) in about 90 % of all cases. Reliable prognostic factors for the stability of the patellofemoral joint after MPFL surgery and satisfaction of the patient have not been established as yet. ⋯ Prognostic study, Level IV.

Multicenter StudyPatterns of loosening of polyethylene keeled glenoid components after shoulder arthroplasty for primary osteoarthritis: results of a multicenter study with more than five years of follow-up.
The aim of this study was to radiographically analyze the long-term glenoid migration patterns following total shoulder arthroplasty to better understand the factors responsible for loosening. ⋯ The three patterns of migration observed in this study underscore the potential importance of the supporting bone beneath the glenoid component. In some shoulders, use of a keel or pegs to provide fixation of a polyethylene component in the absence of good support from subchondral bone may not be sufficient to resist compressive and eccentric forces, resulting in loosening. Preserving subchondral bone may be important for long-term longevity of the glenoid component.

Multicenter Study Comparative Study
Unstable cervical spine fracture after penetrating neck injury: a rare entity in an analysis of 1,069 patients.
The value of cervical spine immobilization after penetrating trauma to the neck is the subject of lively debate. The purpose of this study was to review the epidemiology of unstable cervical spine injuries (CSI) after penetrating neck trauma in a large cohort of patients. ⋯ The overall incidence of unstable CSI after penetrating trauma to the neck is exceedingly low at 0.4%. Following GSW to the neck, an unstable CSI was noted in <1% of patients. After cervical SW, however, no spinal instability was noted precluding the need for spinal precautions in these instances.

Multicenter StudyPosttraumatic anterior-inferior instability of the shoulder: arthroscopic findings and clinical correlations.
The main purpose of our study was to evaluate intra-articular lesions in glenohumeral-instability with arthroscopy and correlate them with clinical findings as well as history of instability. ⋯ Thus we conclude that early surgical stabilization after posttraumatic anterior-inferior shoulder dislocation is necessary to prevent increasing damage within the shoulder joint.
