We retrospectively reviewed 233 patients who underwent primary anterior cruciate ligament reconstruction in order to determine the incidence of concomitant meniscus and cartilage injury, and optimal timing of ligament reconstruction. Among them, 114 (48.9%) and 12 patients (5.2%) had meniscus and cartilage injury, respectively. They had significantly longer time interval from injury to reconstruction than isolated anterior cruciate ligament injured patients. It was preferred that we perform anterior cruciate ligament reconstruction within 4.5 months from the viewpoint of prevention of secondary meniscus and cartilage injury.

To investigate the utility of the X-ray for diagnosing malignant spinal tumors, we examined the findings of X-rays performed around the time of diagnosis of malignant spinal tumors for the pedicle sign, unilateral vertebral body collapse, and type of bone metastasis (osteolytic, osteoblastic or mixed). A retrospective review by a specialist based on MRI and clinical findings revealed a 64% prevalence rate, which was used as a reference value. The prevalence rate was 44% when a non-specialist read the images blindly after being given information only about the chief complaint. Bronchial and intestinal gas, soft tissue shadow and degenerative changes were likely to be mistaken for malignant spinal tumors, and malignant changes in the sacrum were difficult to identify.

Objective: This study aimed to evaluate the factors affecting range of motion (ROM) with DDA2 external fixator and percutaneous pinning for intra-articular fracture of proximal interphalangeal joint (PIPJ). Methods: Ten fingers in ten cases were included this retrospective study with followed up longer than three months. Those fingers were investigated for waiting period till surgery, ROM of PIPJ and distal interphalangeal joint (DIPJ), total ROM (tROM), gap (JG), and step-off (JS) of the joint surface at the time of final observation.

Results: Mean waiting period was 8.3 days, each extension and flexion angles were －11.0 and 89.5° in PIPJ, －6.0 and 60.5° in DIPJ, tROM was 133°, JG and JS were 0.8 and 0.7 mm, respectively. Each of correlation coefficient was between ROM in PIPJ with DIPJ (r=0.47), tROM with waiting period till surgery (r=－0.72), with JG (r=－0.01), and with JS (r=－0.09).

Conclusions: These findings indicated that those fingers were affected to waiting period till surgery and defected to postoperative fixation angle of PIPJ, by contrast, ROM was poorly correlated residual displacement of the fractured joint surface in the short term. Furthermore, those should be exercised aggressively DIPJ as well as PIPJ.

Stomas are occasionally used in the treatment of malignant diseases of the urological and gastrointestinal tracts. Corsets are periodically used for lumbar spine disease; however, there have been very few studies or reports on its use in cases of additional stomas. We treated these cases by utilizing lumbar orthosis by creating a hole in the stoma area.

We treated 10 patients (8 males, 2 females) with an average age of 70.7 (range: 49-85) years. The primary diseases that led to stoma creation were seven cases of rectal cancer, two of bladder cancer, and one of transverse colon cancer. Lumbar diseases observed were four pathological fractures associated with metastatic bone tumors, four osteoporotic fractures, one postoperative lumbar spinal canal stenosis, and one pyogenic discitis. These cases were treated and demonstrated significant improvement in walking ability on the Basel index （P＜0.05).

Corset therapy was effective in preventing loss of mobility in cancer patients with stomas.
