Effect of shoulder abduction on the fixation of humeral greater tuberosity fractures: a biomechanical study for three types of fixation constructs.
An abduction brace and abduction exercises are commonly employed after humeral greater tuberosity fracture repair. However, the effects of glenohumeral abduction on the biomechanical strength have seldom been elucidated. ⋯ The DR group had greatest initial fixation strength at a low abduction angle, whereas the SB group had the highest initial fixation strength at a high abduction angle. The TS group appeared unaffected by the abduction angle.

Results of displaced supracondylar humerus fractures treated with open reduction and internal fixation after a mean 22.4 years of follow-up.
The aim of this study was to evaluate the long-term functional and cosmetic results as well as the sagittal and coronal plane remodeling of displaced supracondylar humerus fractures treated with open reduction and internal fixation. ⋯ We identified the remodeling in the sagittal plane in supracondylar humerus fractures that had been united in flexion. Satisfactory functional and cosmetic results were obtained with the open reduction and internal fixation of displaced supracondylar fractures of the humerus, and no degenerative changes were observed at the long-term follow-up.

Scapula alata: description of a physical therapy program and its effectiveness measured by a shoulder-specific quality-of-life measurement.
To date, there are no published outcomes-based treatment programs to guide clinicians when managing patients with scapula alata. The purposes of this study were to describe a physical therapy program in patients with scapula alata and to evaluate its effect using a shoulder-specific quality-of-life measurement. ⋯ This study described in detail a physical therapy program; the program showed significant benefit. Further research is needed before recommending the program as a potential treatment option.

Heterotopic ossification formation after fracture-dislocations of the elbow.
Heterotopic ossification (HO) is a serious complication of traumatic elbow injuries, particularly fracture-dislocations. Limited data exist in the literature regarding the risk factors associated with HO formation in these injuries. The purpose of this study was to review the incidence of HO after fracture-dislocation of the elbow and to identify potential risk factors associated with its formation. ⋯ HO developed in 77% of patients with multiple attempted closed reductions. We found a 43% incidence of HO in patients surgically treated for elbow fracture-dislocations. Neither time to surgery after the injury nor demographic or other factors relating to the manner in which associated osseous or soft tissue injuries were managed influenced the formation of HO.

Agreement of olecranon fractures before and after the exposure to four classification systems.
Although classification systems of olecranon fractures are important to help choose the best treatment and to predict prognosis, their degree of observer agreement is poorly investigated. The objective of this study was to investigate the intraobserver and interobserver reliability of currently used classification systems for olecranon fractures. Our hypothesis is that the Colton classification presents an acceptable agreement because it is simpler to use; on the other hand, considering the AO classification's complexity, we expect it to reach a lower level of agreement. ⋯ No classification system is widely accepted because it can be affected by interobserver variability, which can raise questions about its use in a research as well as in a clinical context.
