Multicenter Study
Single screw type of lag screw results higher reoperation rate in the osteosynthesis of basicervical hip fracture.
Basicervical hip fractures are relatively rare with greater biomechanical instability compared to the other types of hip fractures. Several studies have reported ambivalent surgical outcomes of basicervical hip fractures. The purpose of this multicenter study was to analyze surgical outcomes of basicervical hip fractures according to the fixation type of proximal femur and lag screw type. ⋯ Basicervical hip fractures treated with osteosynthesis resulted to high rates of surgical complications in this study. However, they could be drastically reduced if CMN with blade type or two integrated screw type were used in the osteosynthesis of basicervical hip fractures.

Regional clinical pathways, a new type of clinical pathway, are practiced with the aim of standardizing and optimizing medical care by cooperation among multiple medical institutions in a region. However, current evaluation of the effectiveness of regional clinical pathways for hip fracture, a major health problem requiring hospitalization for orthopedic surgery, is insufficient. This study aimed to determine the association between regional clinical pathways and postoperative hospital length of stay (LOS) among hip fracture patients. In particular, we focused on the variation in postoperative LOS of hip fracture patients among hospitals and the contribution of regional clinical pathways to this variation. ⋯ Implementation of regional clinical pathways for hip fracture patients at the hospital level was associated with reduced postoperative LOS, regardless of whether or not pathways were implemented at the patient level. This suggests that regional clinical pathways are effective for patient care management in hospitals.

Degloving injuries of the limb are severe and frequently underrated. Few researches are available comparing the results of reattachment of the degloved skin grafts with the vacuum sealing drainage technique and the traditional compression dressing method. In this study, we aimed to compare the treatment outcomes of these two approaches. ⋯ VSD and TCD are equally effective in the management of degloving injuries of the limb; however, VSD technique may potentially have a higher risk of poor results with increased hospital charges. The traditional approach still has its merits in clinical practice, especially in rural hospitals when VSD is not available or unaffordable.

The reference values of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) in patients with lumbar spinal stenosis (LSS) are still unknown. This multicenter cross-sectional survey was performed to determine the reference values and disease-specific characteristics of deterioration of QOL caused by LSS itself, not by aging, through comparison of patients with and without LSS who had an outpatient visit for low back pain by age and sex groups. ⋯ The percentiles of JOABPEQ scores in patients with LSS were clarified and could be used as reference values. Deterioration of QOL caused by LSS itself, not by aging, are characterized by Pain-related disorder, Gait disturbance, Social life disturbance, and Psychological disorders.

Some patients suffer from long-lasting symptoms after whiplash injury. However, there are few reports on the long-term changes in the cervical spine after whiplash injury using imaging tests. The purpose of this longitudinal study was to determine the changes on MRI of the cervical spine 20 years after whiplash injury, and to examine the relationships between changes in the cervical spine on MRI and changes in related clinical symptoms. ⋯ Twenty years after whiplash injury, 95% of the subjects showed a progression of degeneration in the cervical spine. The progression of the intervertebral disc degeneration in the cervical spine on MRI after whiplash injury was not significantly associated with changes in the severity of related clinical symptoms, indicating that the degenerative changes on MRI may reflect the physiological aging process rather than post-traumatic sequelae.
