Earlier studies suggested that while after spinal cord lesions and transplants at birth, the transplants serve both as a bridge and as a relay to restore supraspinal input caudal to the injury (Bregman, 1994), after injury in the adult the spinal cord transplants serve as a relay, but not as a bridge. We show here, that after complete spinal cord(More)
OBJECT The authors have developed a novel technique for percutaneous fusion in which standard microendoscopic discectomy is modified. Based on data obtained in their cadaveric studies they considered that this minimally invasive interbody fusion could be safely implemented clinically. The authors describe their initial experience with a microendoscopic(More)
STUDY DESIGN A retrospective study investigating the clinical outcome of the inside-outside cranial bolt technique for occipitocervical stabilization used to manage rheumatoid arthritis was conducted. OBJECTIVE To evaluate the safety and efficacy of the inside-outside technique for occipitocervical stabilization used to manage rheumatoid patients. (More)
The adult central nervous system is capable of considerable anatomical reorganization and functional recovery after injury. Functional outcomes, however, vary greatly, depending upon size and location of injury, type and timing of intervention, and type of recovery and plasticity evaluated. The present study was undertaken to assess the recovery of skilled(More)
OBJECTIVE Lumbar spinal stenosis and spondylosis are major causes of morbidity among the elderly. Surgical decompression is an effective treatment, but many elderly patients are not considered as candidates for surgery based on age or comorbidities. Minimally invasive surgical techniques have recently been developed and used successfully for the treatment(More)
OBJECTIVE Synovial cysts are a rare cause of lumbar radiculopathy and back pain. Surgical treatment is directed at complete excision of the cyst. We used minimally invasive surgical techniques for a series of patients, to assess the effectiveness of this approach for resection of synovial cysts. METHODS Seventeen patients (10 female and 7 male patients)(More)
OBJECT Experience with minimal-access surgical approaches for revision lumbar surgery has not been previously reported. METHODS During a 7-month period, 10 consecutive patients with recurrent disc herniations underwent revision operations in which microendoscopic discectomy (MED) was performed. Perioperative data and clinical outcomes (according to Macnab(More)
OBJECT Various approaches exist for the treatment of thoracic disc herniation. Anterior approaches facilitate ventral exposure but place the intrathoracic contents at risk. Posterolateral approaches require extensive muscle dissection that adds to the risk of postoperative morbidity. The authors have developed a novel posterolateral, minimally invasive(More)
A craniofacial hemangiopericytoma associated with oncogenic osteomalacia is described and the literature is reviewed. A 46 year-old male with multiple fractures and hypophosphatemia was found to have a craniofacial mass extending from the right ethmoid sinus into the right frontal lobe. Initial detection of the tumor was made with an 111Indium-pentreotide(More)
STUDY DESIGN Feasibility analysis of percutaneous posterolateral thoracic microendoscopic discectomy in a human cadaver model. OBJECTIVE To describe a new, minimally invasive, posterolateral approach to the thoracic spine for the treatment of disc herniations. SUMMARY OF BACKGROUND Thoracoscopic discectomy offers surgeons direct ventral access to(More)
