RESUMO
Background: Prolonged sciatica symptoms may result in disability and consequently, absence from work for a longer period. Up to 10% of patients may need surgery but it is difficult to predict and determine which of these patients would improve spontaneously in comparison to those who might benefit from discectomy surgery. We aimed to determine if delay in the "time to surgery" (TTS) has any adverse effects on the patient reported outcome measures (PROMs). Methods: Eighty-seven patients after exclusions were selected consecutively. PROMs were comprised of pre-operative, six weeks and six months post-operative back and leg pain visual analogue scores (VAS) and Oswestry disability index (ODI). The differences between these scores were correlated with TTS. Minimal clinically important difference (MCID) of 30% improvement for ODI scores and 33% for VAS scores from baseline were considered as significant improvement. Patients were grouped into TTS less than 6 months and TTS greater than 6 months from referral to TTS. The longest TTS was 18 months. Statistical analysis was done using JASP (Version 0.14.0) [computer software]. Results: The TTS was on average 22.5 weeks. MCID for the leg pain VAS was achieved in 90.2% patients with TTS <6 months and in 80.8% with TTS ≥6 months. The MCID for ODI was achieved in 60.7% with TTS <6 months and in 42.0% with TTS ≥6 months. The MCID for back pain VAS was achieved in 73.8% with TTS <6 months and in 50.0% of patients with TTS ≥6 months. Those who achieved the MCID in ODI score between the two groups were analysed using chi-square test with P=0.115. Those who achieved the MCID in VAS leg pain score between the two groups were analysed using chi-square test with P=0.227. No statistical difference was found in ODI and VAS for leg for patients with TTS before or after 6 months. Conclusions: Lumbar discectomies had a positive impact on patient's pain and function in our local district hospital. Delayed surgery of ≥6 months did not cause statistically significant worse outcomes. In the absence of worsening neurological deficit, it may be the wrong approach to define a value for the TTS.
RESUMO
BACKGROUND: This clinical descriptive study aims to establish if differences exist in functional outcomes, to include both leg and lower back pain (LBP) as well as disability, in patients undergoing laminectomy or laminotomy surgery for lumbar spinal stenosis (LSS). METHODS: We conducted a single centre, prospective study of 119 patients undergoing laminectomy or laminotomy surgery for LSS, from 2006 and 2012. Clinical outcomes for back and leg pain were analyses using Oswestry Disability Index (ODI) questionnaires and visual analogue scale (VAS) scores collected preoperatively, at 6 weeks and 1 year. Further analysis subdivided patients into two groups based on initial LBP VAS scores. RESULTS: Fifty-five percent of patients were females (n=65) and 45% males (n=54), with a mean age of 68.7 years and L4/5 being the level most frequently decompressed. Considering all surgeries, a statistically significant reduction in VAS back pain between pre-op and 6 weeks was seen (4.99 to 3.00, P<0.001). There was a significant (P<0.0001) average reductions in LBP by 1.66 units and leg pain by 3.33 units after 1 year, with minimal difference between laminectomy and laminotomy. In the VAS back ≥5 group, laminectomy patient's pain increased by 0.63 units between 6 weeks and 1 year whilst laminotomy patients experienced a reduction in back pain of 0.51 units (P=0.063). ODI scores significantly improved for laminectomy and laminotomy by an average of 19.1%, 95% CI: 13.4-24.9% and 10.8%, 95% CI: 5.8-15.7%, with no statistically significant difference between groups. CONCLUSIONS: No statistically significant differences were demonstrated between laminectomy and laminotomy outcomes, for LBP, leg pain or disability in our institute. On the basis of functional outcomes laminectomy remains a feasible approach in the treatment of lumbar spine stenosis. The data presented in this manuscript provides frequency data for subsequent comparative studies.
RESUMO
The aim of this review is to evaluate the functional results of open reduction and internal fixation of AO type C distal humerus fractures in elderly patients. Twenty patients were recruited in this study with an average age of 73.5 years. AO principles were followed, using dual plating in most and inter-fragmentary screws to obtain stable fixation. Mobilisation was commenced on the first post-operative day. Functional results were 72% good or excellent using the index of Broberg and Morrey, and 93% good or excellent using the Mayo elbow performance index. The average loss of full extension was 17.3° (0-30°) and the average flexion was 131° (90-140°). Radiologically, all fractures were united at review although there was few screw loosening and one implant failure at the lateral column but this did not influence the functional outcome. In conclusion, open reduction and internal fixation of type C distal humerus fractures in elderly patients should continue to be the treatment of choice.
