Indirect decompression for a prior severe C1-2 dislocation causing progressive quadriparesis.

Combined anterior and posterior surgery is frequently chosen for the treatment of prior, severe C1-2 dislocations that occurred during early childhood because of the difficulty in achieving reduction and satisfactory decompression. The authors treated a prior, severe C1-2 dislocation that was causing progressive quadriparesis. The patient was a 14-year-old boy who had suffered a C1-2 fracture-dislocation at 3 years of age and had been treated with a Minerva body jacket cast.

Gender difference of symptom severity in lumbar spinal stenosis: role of pain sensitivity.

Background: Given that there are gender differences in pain perception, it is likely that there are differences in pain responses between men and women with lumbar spinal stenosis (LSS). Furthermore, these differences may lead to different degrees of impairment in both daily activities and quality of life between men and women.

Objective: To elucidate the difference of LSS symptom severity between genders in relation to pain sensitivity.

Association of benign joint hypermobility with spinal segmental motion and its clinical implication in active young males.

Study Design: A retrospective case-control analysis of prospectively collected data.

Objective: First, to evaluate spinal intervertebral mobility in patients with joint hypermobility (JHM) and matched controls without JHM, and second, to investigate the influence of JHM on back pain, disability, and general health status in young males.

Summary Of Background Data: Despite the significance of benign JHM in the musculoskeletal feature, there have been no studies regarding low back pain and segmental motion in subjects with JHM.

The influence of pain sensitivity on the symptom severity in patients with lumbar spinal stenosis.

Background: The symptom severity of back pain/leg pain is not correlated with the severity of degenerative changes and canal stenosis in lumbar stenosis. Considering the individual pain sensitivity might play an important role in pain perception, this discordance between the radiologic findings and clinical symptoms in degenerative lumbar stenosis might originate from the individual difference of pain sensitivity for back pain and/or leg pain.

Objective: To determine the relationship among the clinical symptoms, radiologic findings, and the individual pain sensitivity in the patients with degenerative lumbar spinal stenosis.

Tibial slope and patellar height after opening wedge high tibia osteotomy using autologous tricortical iliac bone graft.

Our aim was to evaluate the alteration in angle of posterior slope of the tibia and the degree of patellar height following medial opening wedge high tibia osteotomy(HTO) using autologous tricortical iliac bone graft in 32 consecutive patients. Twenty three females and nine males underwent medial opening wedge high tibia osteotomy (HTO) using autologous tricortical iliac bone graft in 34 knees (33 primary medial compartment osteoarthritis and 1 idiopathic osteonecrosis of medial tibial condyle). The posterior slope of tibia was determined by the proximal tibial anatomical axis.
