Objective To establish the appropriateness of transforaminal percutaneous endoscopic lumbar diskectomy (PELD) by comparing it with open lumbar microdiskectomy (OLM) for surgical treatment of recurrent lumbar disk herniation. Methods We retrospectively analyzed 83 patients who underwent revision surgery (group A: PELD, 35 cases; group B: OLM, 48 cases) for recurrent lumbar disk herniation between March 2009 and April 2014. All of the patients were followed > 12 months. To evaluate outcomes, we checked the leg and back visual analog scale (VAS), Oswestry Disability Index (ODI), complications, and recurrence for all patients. Results The mean improvement of VAS for leg was 5.97 ± 0.98 for group A and 5.62 ± 1.42 for group B (p = 0.194). The mean improvement of VAS for back pain was 2.71 ± 1.30 for group A and 2.29 ± 1.41 for group B (p = 0.168). The mean improvement of ODI scores was 28.86 ± 3.93 for group A and 28.00 ± 4.22 for group B (p = 0.350). Total surgery-related complications were none for group A and nine for group B (p = 0.009). Group A had one subject with surgery-related neurologic symptoms and group B had four (p = 0.391). Recurrence occurred in two patients in group A and seven patients in group B (p = 0.291). Conclusion PELD and OLM have favorable clinical outcomes in patients with recurrent lumbar disk herniation, and PELD results in fewer complications compared with OLM. Therefore, PELD may be a better alternative to OLM for patients with recurrent lumbar disk herniation.

Caudal lumbar disk herniations (i.e., third lumbar [L3] to seventh lumbar [L7] intervertebral spaces) represent approximately 15% of surgically treated thoracolumbar disk herniations in dogs. A retrospective case-control study was conducted to determine the postoperative outcome of this subset of dogs in the authors' neurosurgical practice. Medical records (1985 through 1996) were reviewed for dogs with caudal lumbar disk herniation confirmed at surgery. Thirty-six cases were identified. For each case, two dogs that underwent surgical treatment for upper motor neuron thoracolumbar disk herniation (tenth thoracic [T10] to L3 intervertebral spaces) were selected as controls. Probabilities of functional recovery for cases and controls were 81% and 85%, respectively (p value of 0.49). In dogs with caudal lumbar disk herniation, complete sensorimotor loss was the only significant predictor of functional recovery (p value of 0.005). Disk herniations that occur at the thoracolumbar junction and those that occur in the caudal lumbar region should not be considered to be different in terms of surgical treatment and postoperative outcome. The lower motor neuron signs that often accompany caudal lumbar disk herniation reflect the site of spinal cord injury and do not necessarily predict a poor prognosis.

The recent development of the scanning electron microscope has added great impetus to the study of ultrastructural details of normal human ossicles. A thorough description of the ultrastructure of the human ossicles is required in order to determine changes associated with disease processes following medical or surgical treatment.Human stapes crura were obtained at the time of surgery for clinical otosclerosis and from human cadaver material. The specimens to be examined by the scanning electron microscope were fixed immediately in the operating room in a cold phosphate buffered 2% gluteraldehyde solution, washed with Ringers, post fixed in cold 1% osmic acid and dehydrated in graded alcohol. Specimens were transferred from alcohol to a series of increasing concentrations of ethyl alcohol and amyl acetate. The tissue was then critical point dried, secured to aluminum stubs and coated with gold, approximately 150A thick on a rotating stage in a vacuum evaporator. The specimens were then studied with the Kent-Cambridge S4-10 Scanning Electron Microscope at an accelerating voltage of 20KV.
