objective hereditary spastic paraplegia (hsp) is a degenerative disease of genetic origin affecting the corticospinal tracts in the spinal cord. there are three forms of inheritance: autosomal dominant hsp, autosomal rececive hsp and x-linked hsp. this disease is characterized by progressive spasticity of leg muscles with varying degrees of stiffness and weakness of other muscle groups. in this...

a 48‑year‑old morbidly obese woman with a left medial meniscal tear and moderately severe degenerative joint disease (djd) reported for 14‑month follow‑up visit from arthroscopic surgery. she reported a resolution of pain, swelling and an improved range of motion (rom). the patient was first evaluated 14 months ago, and at that time was considered a strong candidate for total knee replacement d...

in this study to determine whether spine stiffness is predictive of clinical results after lumbar spinal fusion for spinal stenosis, a total of 78 patients were measured intraoperatively with kocher clamp manual distraction technique to determine motion segment stiffness then spinal fusion was performed for any loose segment. ‎statistical analysis revealed that stiffness measurement correlate w...

Osteoporosis has become a major medical problem as the aged population of the world rapidly grows. Osteoporosis predisposes patients to fracture, progressive spinal deformities, and stenosis, and is subject to be a major concern before performing spine surgery, especially with bone fusions and instrumentation. Osteoporosis has often been considered a contraindication for spinal surgery, while i...
