The use of closed suction drainage after spinal surgery remains controversial. The purpose of this study was to determine the indications for closed suction drainage after single-level lumbar surgery. Two hundred patients who were scheduled to undergo single-level lumbar surgery without fusion were prospectively randomized into two groups. One group had a(More)
STUDY DESIGN The risk factors for complications and complication and survival rates in patients with metastatic disease of the spine were reviewed. A retrospective study was performed. OBJECTIVES To determine the surgical complication and survival rates of patients with metastatic disease of the spine and risk factors for complication occurrence. (More)
Anterior cervical fusion was initially described in the 1950s for cervical spondylotic radiculopathy. The indications for this procedure in the management of soft disc herniation have not been clearly defined. In addition, controversy exists as to whether a cervical soft herniation should be managed by an anterior approach or a posterior cervical(More)
Pulmonary function was correlated with patient age and degree of thoracic scoliosis in 25 patients with Duchenne muscular dystrophy in a retrospective, longitudinal study. The observed forced vital capacity (FVC) was found to peak at approximately the age when standing ceases, then to decline rapidly. Thoracolumbar curves were found to be insignificant in(More)
Autogenous bone grafts from the ilium are frequently harvested for purposes of bone union and/or stability. Although some donor site complications may be unavoidable, awareness of the anatomy and complications may aid in planning the approach and minimizing the risks. Documented donor site complications include pain, nerve and arterial injury, peritoneal(More)
Fifty patients who had spinal stenosis associated with degenerative lumbar spondylolisthesis were prospectively studied clinically and radiographically to determine if concomitant intertransverse-process arthrodesis provided better results than decompressive laminectomy alone. There were thirty-six women and fourteen men. The mean age of the twenty-five(More)
STUDY DESIGN This prospective study analyzed the influence of transpedicular instrumented on the operative treatment of patients with degenerative spondylolisthesis and spinal stenosis. OBJECTIVES To determine whether the addition of transpedicular instrumented improves the clinical outcome and fusion rate of patients undergoing posterolateral fusion(More)
Four patients who had low-back pain and sciatica were diagnosed as having a lumbar intraspinal extradural synovial cyst adjacent to a facet joint between the fourth and fifth lumbar vertebrae. The patients ranged in age from forty-nine to seventy-one years, and the symptoms and signs involved the fourth or fifth lumbar-nerve roots. Roentgenographically,(More)
Intraspinal synovial cysts are usually located in the lower lumbar spine in association with osteoarthritis of the facet joints, and they are most accurately diagnosed by using CT. Surgical removal of intraspinal synovial cysts implicated in the development of radiculopathy has resulted in symptomatic relief. A nonoperative method of treatment consists of(More)
STUDY DESIGN This study evaluated clinical and magnetic resonance imaging differences of patients treated surgically for lumbar disc herniation. Clinical follow-up and magnetic resonance imaging evaluation of epidural fibrosis were used to assess patient outcome. OBJECTIVES The purpose of this study was to evaluate the difference in clinical outcome with(More)
