Proximal humeral fractures Risk factors associated with functional outcomes in arthroplasty / 中华创伤骨科杂志

Risk factors associated with poorer functional outcome after shoulder arthroplasty varied widely by study and by fracture type. The most common risk factors were increased age and greater tuberosity displacement or osteotomy. The overall functional and postoperative outcomes after shoulder arthroplasty were favorable across most studies. However, some studies were of poorer quality resulting in low methods scores and, therefore, the results of these studies should be viewed with caution.

Acute nondisplaced scaphoid fractures Operative versus nonoperative management / 中华创伤骨科杂志

There is moderate evidence to support the use of internal screw fixation for treating nondisplaced scaphoid fractures in lieu of using cast immobilization. It appears that patients receiving internal screw fixation may heal at a quicker rate and return to work sooner than patients receiving east immobilization. It' s unclear how effective they are at their job or whether the early return to work in the operative group causes any functional limitations.
