Skull fracture and epidural hematoma caused by use of a Mayfield skull clamp in an adult patient with chronic hemodialysis: a case report.

Background: Mayfield skull clamps are widely used and indispensable in current neurosurgery. Complications such as skull fractures or intracranial hematoma from using a Mayfield skull clamp have largely been reported in the pediatric population, are likely related to the relative thinness of the skull, such as in patients with hydrocephalus, and are extremely rare in adults. Here, we report a case of skull fracture and epidural hematoma caused by a Mayfield skull clamp used for posterior decompression surgery in an adult patient with chronic hemodialysis.

The nature of osteoporotic low back pain without acute vertebral fracture: A prospective multicenter study on the analgesic effect of monthly minodronic acid hydrate.

Background: Patients with osteoporosis but no evidence of fracture can sometimes report low back pain. However, few studies have evaluated the nature of osteoporotic low back pain in a clinical situation. Therefore, the aim of this study was to examine the nature of osteoporotic low back pain without fracture, and the analgesic effect of minodronic acid hydrate on such pain.

Effects of Incentive Spirometry on Respiratory Motion in Healthy Subjects Using Cine Breathing Magnetic Resonance Imaging.

Objective: To investigate the effectiveness of incentive spirometry on respiratory motion in healthy subjects using cine breathing magnetic resonance imaging (MRI).

Methods: Ten non-smoking healthy subjects without any history of respiratory disease were studied. Subjects were asked to perform pulmonary training using incentive spirometry every day for two weeks.

Accuracy of Pedicle Screw Placement in Scoliosis Surgery: A Comparison between Conventional Computed Tomography-Based and O-Arm-Based Navigation Techniques.

Study Design: Retrospective study.

Purpose: We compared the accuracy of O-arm-based navigation with computed tomography (CT)-based navigation in scoliotic surgery.

Overview Of Literature: No previous reports comparing the results of O-arm-based navigation with conventional CT-based navigation in scoliotic surgery have been published.

Rod fracture after long construct fusion for spinal deformity: clinical and radiographic risk factors.

Background: No reports have been published on detailed risk factors for rod fracture after spinal deformity correction and fusion. The purpose of this study was to analyze clinical and radiographic risk factors of rod fracture after long construct fusion for spinal deformity.

Methods: The survey subjects were 155 cases who were diagnosed with spinal deformity and underwent correction and fusion surgery with long construct instrumentation (>3 levels, average 10.

Virtual endoscopic imaging of the spine.

Study Design: Prospective trial of virtual endoscopy in spinal surgery.

Objective: To investigate the utility of virtual endoscopy of the spine in conjunction with spinal surgery.

Summary Of Background Data: Several studies have described clinical applications of virtual endoscopy to visualize the inside of the bronchi, paranasal sinus, stomach, small intestine, pancreatic duct, and bile duct, but, to date, no study has described the use of virtual endoscopy in the spine.

Health-related quality of life and low back pain of patients surgically treated for scoliosis after 21 years or more of follow-up: comparison among nonidiopathic scoliosis, idiopathic scoliosis, and healthy subjects.

Study Design: A case-control study.

Objective: To compare health-related quality of life and low back pain of healthy subjects with those of patients with nonidiopathic scoliosis (non-IS) and idiopathic scoliosis (IS) 21 years or more after surgery.

Summary Of Background Data: There have been a very small number of reports on long-term results of surgery for non-IS.

Long-term clinical outcomes of surgery for adolescent idiopathic scoliosis 21 to 41 years later.

Study Design: A case control study.

Objective: To determine the clinical outcome of middle-aged patients surgically treated for adolescent idiopathic scoliosis and to compare their outcomes with assessments of age- and sex-matched healthy controls.

Summary Of Background Data: Several long-term follow-up studies have been published on the clinical outcomes of surgical treatment for adolescent idiopathic scoliosis in patients who have reached their 20s or 30s.

[A case of allopurinol-induced muscular damage in a chronic renal failure patient].

A 73-year-old woman with chronic renal failure developed generalized muscular weakness and pain 6 days after the start of allopurinol treatment(200 mg/day). Routine laboratory tests revealed elevated levels of serum creatine kinase, and the patient was clinically diagnosed as rhabdomyolysis, due probably to severe myositis. A high level of serum oxipurinol, the chief active metabolite of allopurinol, was also revealed.
