Review
The reverse shoulder arthroplasty conceived by Paul Grammont in 1985 has gradually gained popularity as a treatment for multiple shoulder diseases. Unlike previous reverse shoulder prosthesis characterized by unsatisfactory results and a high glenoid implant failure rate, the Grammont design has immediately shown good clinical outcomes. This semi constrained prosthesis solved the issues of the very first designs by medializing and distalizing the center of rotation with an increased stability of the replacement of the component. The indication was initially limited to cuff tear arthropathy (CTA). It has then been expanded to irreparable massive cuff tears and displaced humeral head fractures. The most frequent problems of this design are a limited postoperative external rotation and scapular notching. Different modifications to the original Grammont design have been proposed with the aim of decreasing the risk of failure and complications and improving the clinical outcomes. Both the position and version/inclination of the glenosphere and the humeral configuration (e.g. neck shaft angle) influence the RSA outcomes. A lateralized glenoid (whether with bone or metal) and a 135° Inlay system configuration leads to a moment arm which is the closest to the native shoulder. Clinical research will focus on implant designs reducing bone adaptations and revision rate, strategies to prevent more effectively infections. Furthermore, there is still room for improvement in terms of better postoperative internal and external rotations and clinical outcomes after RSA implanted for humeral fracture and revision shoulder arthroplasty.

INTRODUCTION
Humeral shaft fractures can be treated non-operatively or operatively. The optimal management is subject to debate. The aim was to compare non-operative and operative treatment of a humeral shaft fracture in terms of fracture healing, complications, and functional outcome.
METHODS
Databases of Embase, Medline ALL, Web-of-Science Core Collection, and the Cochrane Central Register of Controlled Trials (CENTRAL) were systematically searched for publications reporting clinical and functional outcomes of humeral shaft fractures after non-operative treatment with a functional brace or operative treatment by intramedullary nailing (IMN; antegrade or retrograde) or plate osteosynthesis (open plating or minimally invasive). A pooled analysis of the results was performed using MedCalc.
RESULTS
A total of 173 studies, describing 11,868 patients, were included. The fracture healing rate for the non-operative group was 89% (95% confidence interval (CI) 84-92%), 94% (95% CI 92-95%) for the IMN group and 96% (95% CI 95-97%) for the plating group. The rate of secondary radial nerve palsies was 1% in patients treated non-operatively, 3% in the IMN, and 6% in the plating group. Intraoperative complications and implant failures occurred more frequently in the IMN group than in the plating group. The DASH score was the lowest (7/100; 95% CI 1-13) in the minimally invasive plate osteosynthesis group. The Constant-Murley and UCLA shoulder score were the highest [93/100 (95% CI 92-95) and 33/35 (95% CI 32-33), respectively] in the plating group.
CONCLUSION
This study suggests that even though all treatment modalities result in satisfactory outcomes, operative treatment is associated with the most favorable results. Disregarding secondary radial nerve palsy, specifically plate osteosynthesis seems to result in the highest fracture healing rates, least complications, and best functional outcomes compared with the other treatment modalities.

Scapular fractures are rare injuries that require different treatment strategies. Nondisplaced fractures and the majority of scapular body fractures can be treated conservatively, while surgical treatment should be considered for displaced fractures involving the glenoid. Displaced glenoid fractures of appropriate size and intra-articular step formation should be treated surgically. Different classification systems for scapular fractures can support the treatment decision. Postoperative and posttraumatic management should include early mobilization to achieve a good functional outcome. Clear recommendations and treatment algorithms at the evidence level are not available and long-term outcomes of scapular fractures are the subject of further investigation. The results published so far show good to excellent results for surgical and conservative treatment, depending on the type of fracture. Individual patient factors should be considered when planning treatment.

PURPOSE OF REVIEW
Proximal humerus fracture dislocations typically result from high-energy mechanisms and carry specific risks, technical challenges, and management considerations. It is vital for treating surgeons to understand the various indications, procedures, and complications involved with their treatment.
RECENT FINDINGS
While these injuries are relatively rare in comparison with other categories of proximal humerus fractures, fracture dislocations of the proximal humerus require treating surgeons to consider patient age, activity level, injury pattern, and occasionally intra-operative findings to select the ideal treatment strategy for each injury. Proximal humerus fracture dislocations are complex injuries that require special considerations. This review summarizes recent literature regarding the evaluation and management of these injuries as well as the indications and surgical techniques for each treatment strategy. Thorough pre-operative patient evaluation and shared decision-making should be employed in all cases. While nonoperative management is uncommonly considered, open reduction and internal fixation (ORIF), hemiarthroplasty, and reverse total shoulder replacement are at the surgeon's disposal, each with their own indications and complication profile.

BACKGROUND
Upper extremity (UE) fragility fractures are common and strong predictors of subsequent fractures. To investigate the relative importance of an UE fragility fracture in determining future fracture risk, we conducted a cross-sectional study to compare future fracture risk between patients presenting for osteoporosis evaluation after an UE fragility fracture and a similarly aged cohort of patients without an UE fracture.
METHODS
In all, 129 UE fracture patients seen in our bone health clinic (BHC) and 114 non-fracture UE fracture patients seen in an UE clinic completed clinic intake surveys assessing for fracture risk factors. Prefracture fracture risk (PFFR) and fracture risk assessment tool (FRAX) scores estimated the future fracture risks at the timepoint before and after the UE fragility fracture event, respectively. The primary study outcome was the 10-year risk of future fracture.
RESULTS
The 10-year probability of major osteoporotic and hip fractures were significantly higher among the BHC group when estimated with FRAX. When estimated with PFFR score, there was no difference in the 10-year probability of hip fracture between the groups. Prevalence of secondary osteoporosis and glucocorticoid use was higher in the BHC group, and prevalence of rheumatoid arthritis was higher in the UE clinic group.
CONCLUSIONS
This study underscores the importance of an UE fragility fracture in determining the risk of future fracture. A fragility fracture of the UE should be considered a sentinel event and physicians who evaluate these patients should recognize them as a high-risk group for future hip fracture.

The origins of contemporary orthopedics can be traced all the way back to antiquity. Despite the absence of modern imaging techniques, a few bright minds were able to lay the groundwork for understanding these fractures. This historical review will cover the process behind the various treatments for elbow fractures, such as splinting and casting, mobilization, amputation, fracture fixation, arthroplasty, and arthroscopy.
