Randomized Controlled Trial Comparative Study Clinical TrialPostoperative pain after lumbar disc surgery: a comparison between parenteral ketorolac and narcotics.
Lumbar discectomy is a common elective surgical procedure but many patients still experience postoperative back pain which may delay hospital discharge. We therefore evaluated the efficacy of a parenteral non-steroidal antiinflammatory agent, ketorolac, for the management of post-surgical pain. ⋯ These results suggest that ketorolac, when used with PRN narcotics, is more effective than PRN narcotics alone for postoperative pain following lumbar disc surgery. In addition, this strategy also may contribute to early discharge from hospital after lumbar disc surgery.

Review Case ReportsSyringobulbia caused by delayed postoperative tethering of the cervical spinal cord - delayed complication of foramen magnum decompression for Chiari malformation.
Postoperative tethering of the high cervical spinal cord is a rare cause of neurological deterioration after foramen magnum decompression (FMD) with duraplasty for Chiari type I malformation. A review of the literature revealed that only 5 cases have been reported. This entity is not widely known to occur as a complication of the common surgical procedure for Chiari type I malformation. ⋯ Follow-up MR images provided significant information on the cervical spinal cord tethering after FMD with duraplasty for Chiari malformation. We encourage sharp surgical detethering and duraplasty with Gore-Tex to avoid retethering. Early recognition and treatment of this unusual but important complication are emphasized.

ReviewNon-neoplastic cystic lesions of the sellar region presentation, diagnosis and management of eight cases and review of the literature.
The differential diagnosis of a sellar lesion includes pituitary adenoma, cranio-pharyngioma, tumour cyst, benign cyst, and other less common lesions such as aneurysm, squamous cell carcinoma and metastases. Pure cystic lesions within the sella turcica are not uncommon and may appear clinically and radiologically as pituitary adenoma. Intrasellar cysts are broadly classified as neoplastic or non-neoplastic; the latter may be primary lesions of the pituitary fossa or they may arise from the parasellar region and invade into the sella. ⋯ Investigations included computed tomography scan of the head for all and magnetic resonance imaging for six (75%) patients. Work-up included endocrinological and opthalmological evaluations. All presented with headache; six (75%) had visual acuity change, two (25%) had evidence of visual field defects, four (50%) had optic atrophy on fundoscopy, three (37.5%) had endocrine symptoms and hormone reduction was found in four (50%).

Comparative StudyComparison of two types of surgery for thoraco-lumbar burst fractures: combined anterior and posterior stabilisation vs. posterior instrumentation only.
This retrospective study compares clinical outcome following two different types of surgery for thoracolumbar burst fractures. Forty-six patients with thoracolumbar burst fractures causing encroachment of the spinal canal greater than 50% were operated on within 30 days performing either: combined anterior decompression and stabilisation and posterior stabilisation (Group 1) or posterior distraction and stabilisation using pedicle instrumentation (AO internal fixator) (Group 2). We evaluated: neurological status (Frankel Grade), spinal deformities, residual pain, and complications. ⋯ The clinical outcome was similar in both groups, and all but one patient with neurological deficits improved by at least one Frankel grade. Indirect decompression of the spinal canal by posterior distraction and short-segment stabilisation with AO internal fixator is considered appropriate treatment for the majority of unstable thoracolumbar burst fractures. This is a less extensive surgical procedure than a combined anterior and posterior approach.

Randomized Controlled Trial Clinical TrialPostoperative pain therapy after lumbar disc surgery.
This study was undertaken to determine whether a special postoperative pain administration of tramadol and diclofenac provides any benefits in patients who underwent microsurgical lumbar discectomy. ⋯ The results suggest that the application of tramadol and diclofenac during the first 48 hours after lumbar microdiscectomy results in a reduction in postoperative pain without complications. We suggest that the use of this combination can be a beneficial adjunct to lumbar disc surgery.
