STUDY DESIGN: Prospective observational study. PURPOSE: To assess the clinical outcome after early versus late decompression for traumatic cervical cord injury. OVERVIEW OF LITERATURE: Traumatic spinal cord injury is common globally with the most tragic outcomes in the cervical spine. Although recent studies have shown that early decompression results in more favourable outcome, its authority is yet to be established. METHODS: Study on 98 patients with a traumatic cervical cord injury was conducted over a period of 5 years. The patients who were operated on within 24 hours of the onset of the primary injury (n=34) were classified as the early group, and those who were operated on after 24 hours of the onset of the injury (n=64) were categorized as the late group. The outcome of both the groups was assessed using the American Spinal Injury Association (ASIA) Impairment Scale (AIS) at the 6-month follow-up. RESULTS: The patients in the early group were operated on at a mean time of 18.4 hours (range, 13-24 hours) while patients were operated on at a mean time of 52.7 hours (range, 31-124 hours) in the late group. At the 6-month follow-up, 7 (23.3%) in the early group and 5 (8.7%) in the late group showed >2 grade improvement in the AIS. CONCLUSIONS: The results of patients undergoing decompression within 24 hours of the injury are better than those who are operated on later. An attempt should be made to decompress the traumatic cervical spine early in all possible cases.

STUDY DESIGN: Fifty patients surgically treated for tethered cord syndrome (TCS) were retrospectively studied at Liaquat National Hospital, Karachi from 2010 until 2014. PURPOSE: To assess the common presentations of TCS in our part of the world and the surgical outcome of the different presentations. OVERVIEW OF LITERATURE: TCS is a stretch-induced functional disorder of the spinal cord with its caudal part anchored by an inelastic structure, which results in characteristic symptoms and signs. Due to the variety of lesions and clinical presentations and the absence of high-quality clinical outcome data, the decision regarding treatment is difficult. METHODS: Fifty consecutive patients with TCS were reviewed retrospectively with a follow-up period of 12–48 months. The majority of the patients were 0-15 years of age with the mean age of 4 years. The presenting complaints and the associated pathologies were documented, and the patients were assessed using the new Karachi TCS severity scale for clinical assessment. RESULTS: Eighty five percent of the patients with thickened filum terminale improved. Sixty six percent of the patients with diastematomyelia, 60% with lipoma and only 46% with myelomeningocele showed clinical improvement postoperatively. Sixty two percent of the patients who presented with paraperesis improved following surgery while 37% remained stable and only one patient deteriorated. Back and leg pain improved in 93% of patients and 50% of patients with urinary impairment improved. CONCLUSIONS: Outcome of patients with TCS varies according to pathology and severity of symptoms. Diastematomyelia and thickened filum had the best outcome. The Karachi TCS severity scale is a valid tool for future studies.

STUDY DESIGN: Randomized controlled trial. PURPOSE: The purpose of this study was to compare pregabalin and gabapentin for mean postoperative visual analog score (VAS) for pain in patients undergoing single-level lumbar microdiscectomy for intervertebral disc prolapse at a tertiary care hospital. OVERVIEW OF LITERATURE: Pregabalin has a superior pharmacokinetic profile and analgesic effect at lower doses than gabapentin; however, analgesic efficacy must be established during the perioperative period after lumbar spine surgery. METHODS: This randomized controlled trial was carried out at our institute from February to October 2011 on 78 patients, with 39 participants in each study group. Patients undergoing lumbar microdiscectomy were randomized to group A (gabapentin) or group B (pregabalin) and started on trial medicines one week before surgery. The VAS for pain was recorded at 24 hours and one week postoperatively. RESULTS: Both groups had similar baseline variables, with mean ages of 42 and 39 years in groups A and B, respectively, and a majority of male patients in each group. The mean VAS values for pain at 24 hours for gabapentin vs. pregabalin were comparable (1.97±0.84 vs. 1.6±0.87, respectively; p=0.087) as were the results at one week after surgery (0.27±0.45 vs. 0.3±0.46, respectively; p=0.79). None of the patients required additional analgesia postoperatively. After adjusting for age and sex, the VAS value for group B patients was 0.028 points lower than for group A patients, but this difference was not statistically significant (p=0.817, R²=0.018). CONCLUSIONS: Pregabalin is equivalent to gabapentin for the relief of postoperative pain at a lower dose in patients undergoing lumbar microdiscectomy. Therefore, other factors, such as dose, frequency, cost, pharmacokinetics, and side effects of these medicines, should be taken into account whenever it is prescribed.
