Effects of glenohumeral internal rotation deficit on baseball pitching among pitchers of different ages
Previous studies have reported that glenohumeral internal rotation deficit (GIRD) may increase the risk of shoulder injury. However, the effects of GIRD on baseball pitching among pitchers of different age groups are still unclear. (Source: Journal of Shoulder and Elbow Surgery)

Glenoid component loosening associated with increased critical shoulder angle at midterm follow-up
Glenoid component loosening is a common failure mode of total shoulder arthroplasty (TSA). A larger critical shoulder angle (CSA) may cause superior glenoid component loading and more rapid component loosening. The purpose of this study was to define the relationship between the CSA and glenoid component loosening in midterm follow-up after TSA. (Source: Journal of Shoulder and Elbow Surgery)

The effectiveness of a modified Metaizeau technique in fixation of adult radial neck fractures: a prospective study with a modification of the Broberg-Morrey classification
The incidence of adult radial neck fractures is lower compared with its pediatric counterpart. The literature on adult radial neck fracture management is limited; also, there is a lack of a detailed fracture classification system. In our study, we are evaluating the modified Metaizeau technique for the treatment of adult radial neck fractures. We also describe a modification to the existing fracture classification proposed by Broberg and Morrey to make it more inclusive of different fracture patterns.

Letter to the Editor regarding Trikha et al: “Retrospective analysis of proximal humeral fracture-dislocations managed with locked plates”
I read the article titled “Retrospective analysis of proximal humeral fracture-dislocations managed with locked plates” by Trikha et al3 with great interest. The authors have made an effort to clarify concerns about the success of osteosynthesis in such a complex scenario, and at the same time, possible complications ar e detailed. But as a reader and clinician, I always have doubt. Is it possible to have persistent instability in cases with 3- or 4-part anterior fracture-dislocation of the shoulder? The previous published series also did not mention the redislocation or persistent instability in such a sc...

An important lesson in assessing neurovascular involvement in proximal humeral fractures: the presence of neuropathic pain in a dysvascular limb
Proximal humerus fracture is a common upper limb fracture with an incidence of around 5%.12,13,20 It is often a result of a high-energy injury in the younger population; in the elderly, it is often due to a trivial fall.6,10 The proximity of the infraclavicular plexus and the brachial artery (the brachial bundle) to the fracture site can result in a variety of possible neurovascular presentations, making the injury uniquely challenging.22 Hence, clinicians should maintain a high index of suspicion for neurovascular compromise complicating even a simple proximal humerus fracture.

Isolated suprascapular mononeuropathy following nondisplaced scapular fracture
Fractures of the scapula are relatively rare, accounting for only 0.4%-0.9% of all fractures and for only about 3%-5% of fractures to the shoulder girdle.2 Given the scapula's extensive muscular envelope and rich blood supply, fractures have traditionally been treated nonoperatively, healing reliably and without compromise of shoulder girdle function. The suprascapular nerve (SSN), which innervates the supraspinatus and infraspinatus muscles, lies in intimate contact with the scapula and is vulnerable in the setting of bony injury.

The effect of a radial neck notch on press-fit stem stability: a biomechanical study on 7 cadavers
Minimal micromotion is necessary for osteointegration of cementless radial head prostheses. When radial head fractures extend longitudinally, where the neck cut for prosthetic replacement should be made is uncertain. We hypothesized that complete resection of the notched portion of a radial neck confers no advantage in initial stability compared with not resecting the defect and inserting the implant into a notched radial neck.

Radiologic and clinical evaluation of a bioabsorbable collagen implant to treat partial-thickness tears: a prospective multicenter study

The ability to induce new tissue formation and limit tear progression in intermediate- and high-grade partial-thickness tears without surgical repair may represent a significant advancement in the treatment paradigm for these lesions.

Epidemiology of glenohumeral dislocation and subsequent instability in an urban population
Glenohumeral dislocation is the most commonly encountered adult joint instability. The epidemiology in the United Kingdom and worldwide is unclear and often limited to young, active groups that are not representative of general populations. Information regarding epidemiology and outcome from a first dislocation is useful for trauma service planning and patient counseling. We calculated the incidence of shoulder instability after a first dislocation in our urban population and investigated predictors of recurrent instability.
