The treatment of clavicular shaft fractures with an innovative locked intramedullary device.
Displaced and shortened clavicular shaft fractures can be treated by intramedullary fixation; however, hardware migration and soft tissue irritation at the insertion site have complicated its use. The aim of this study was to determine whether the new Sonoma CRx intramedullary device (Sonoma Orthopedic Products Inc, Santa Rosa, CA, USA) could be used successfully to treat displaced and shortened clavicular shaft fractures and restore the functional capacity of shoulder without the development of secondary complications. ⋯ The Sonoma CRx is a good alternative device to treat displaced and shortened clavicular shaft fractures and restore the functional capacity of the shoulder. Future research should focus on when nailing and plating should be used to treat clavicular shaft fractures most optimally.

Analysis of perioperative complications in patients after total shoulder arthroplasty and reverse total shoulder arthroplasty.
Data directly comparing the perioperative complication rates between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA) are limited. ⋯ We found that RTSA patients, compared with TSA patients, had significantly longer length of stay, higher hospital charges that are not completely attributable to increased implant costs alone, and increased rates of perioperative complications.

Patient age is a factor in early outcomes after shoulder arthroplasty.
Elderly and young patients alike are undergoing shoulder replacement at increased rates. In an era of outcomes reporting, risk adjustment, and cost containment, identifying patients likely to have adverse events is increasingly important. Our objective was to determine whether patient age is independently associated with postoperative in-hospital complications or increased hospital charges after shoulder arthroplasty. ⋯ Older patients tend to have longer hospital stays, an increased incidence of postoperative anemia, and slightly higher charges after shoulder arthroplasty. Advanced age is not associated with an increased incidence of pulmonary embolism, infection, and cardiac complications. Further research is warranted to explain the relationship between age and early postoperative outcomes.

Upregulation of transforming growth factor-β signaling in a rat model of rotator cuff tears.
Muscle atrophy, fatty infiltration, and fibrosis of the muscle have been described as important factors governing outcome after rotator cuff injury and repair. Muscle fibrosis is also thought to have a role in determining muscle compliance at the time of surgery. The transforming growth factor-β (TGF-β) pathways are highly conserved pathways that exert a potent level of control over muscle gene expression and are critical regulators of fibrosis in multiple organ systems. It has been shown that TGF-β can regulate important pathways of muscle atrophy, including the Akt/mammalian target of rapamycin pathway. The purpose of this study was to evaluate the expression of TGF-β and its downstream effectors of fibrosis after a massive rotator cuff tear (RCT) in a previously established rat model. ⋯ TGF-β signaling is significantly upregulated in rat supraspinatus muscles after RCTs.

Meta Analysis Comparative StudyDelayed versus early motion after arthroscopic rotator cuff repair: a meta-analysis.
We conducted a meta-analysis of randomized trials to compare delayed vs early motion therapy on function after arthroscopic rotator cuff repair. ⋯ The current meta-analysis did not identify any significant differences in functional outcomes and relative risks of recurrent tears between delayed and early motion in patients undergoing arthroscopic rotator cuff repairs. A statistically significant difference in forward elevation range of motion was identified; however, this difference is likely clinically unimportant.
