The presence of short malunion of clavicle fractures could result in alterations in static scapular position and dynamic scapular motion. Nevertheless, no report has ever addressed the kinematic changes of the scapula in patients with short malunion of clavicular fractures. The goal of this study was to compare the changes of shoulder function, and the consequent scapular kinematic changes between the fractured side and the sound side of the shoulder in non-surgically treated patients. ⋯ This study showed that significant changes in scapular kinematics and shoulder function were found after short malunion of clavicle fractures. Recognition and evaluation of the changes could lead to a comprehensive framework regarding the treatment of shortened clavicle fractures.

The aim of the present study was to identify the clinical and radiologic factors affecting functional outcomes in patients with a distal radius fractures (DRFs) treated by volar locking plate fixation. ⋯ Because the ulnar variance after surgery is the modifiable factor in contrast with other factors such as diabetes and age, surgeons should pay attention to restore ulnar variance to improve functional outcomes during volar locking plate fixation in patients with distal radius fractures.

A population approach to analyze the effectiveness of a back extension exercise "One Stretch" in patients with low back pain: A replication study.
We examined the effectiveness of an intervention using a standing back extension exercise called "One Stretch", based on the McKenzie method, in improving or preventing low back pain and disability in Japanese care workers. ⋯ The population approach about the exercise "One Stretch" led to better compliance with the exercise, and was effective for improving or preventing low back pain and in decreasing the likelihood of having a medical consultation for low back pain.

To review the results of the treatment of post-traumatic chronic osteomyelitis of lower limbs by bone transport technique using mono-lateral external fixator. ⋯ 1. Bone transport technique using mono-lateral external fixator is an effective method for the treatment of post-traumatic chronic osteomyelitis. 2. Early BGPO intervention after bone transport is a feasible method to shorten the external fixation time and the total duration of treatment.

Ossification of the posterior longitudinal ligament (OPLL) and ossification of the ligamentum flavum (OLF) are characterized by replacement of ligamentous tissue by ectopic new bone formation. Although the background of both diseases might be similar, there are some differences between two diseases. Some patients have both OPLL and OLF. However, the incidence of both OPLL and OLF is still unclear and the precise lesions have not been investigated, yet. This study was conducted to evaluate OLF of the whole spine in patients with cervical OPLL and to analyze the relationship of the ossified lesions between OLF and OPLL. ⋯ This study demonstrated 64.6% of the patients with cervical OPLL had OLF, mainly in the thoracic spine. However, there was no relationship regarding the severity of the ossified lesions between OPLL and OLF. CT analysis of the whole spine should be carried out for the early detection of OPLL and OLF in patients with cervical OPLL.
