Abstract

Lumbar disc surgery in carefully selected patients who have failed conservative treatments can significantly improve quality of life. Minimally invasive treatment of lumbar disc herniation has been popularized in recent years. The aim of the study was to assess the outcome of minimal invasive (loupe) discectomy among lumbar disc prolapse patients in Sulaimani. A prospective study carried out in Shar and Sulaimani Teaching hospitals in Sulaimani city for period from 1st of February, 2013 to end of June, 2014 on sample of 30 patients with single level lumbar disc prolapse admitted to orthopedic units. The data were collected by the researcher through direct interview and filling a prepared questionnaire. The outcome of surgery was evaluated by comparing the symptoms (back pain, leg pain, and leg parathesia) and the muscle power grading (EHL & FHL) of the patients pre- and post-operatively. Mean age of studied patients was 39.1 ± 9.3 years. Males were more than females. Disc prolapse level was L4-L5 among 17 and L5-S1 among 13 patients. Studying the symptoms pre- and post-operatively, revealed significant decrease in leg pain, leg parathesia and back pain post-operatively (p < 0.001). Studying EHL & FHL power grading pre- and post-operatively, revealed significant increase in muscle power grades 4 and grade 5 postoperatively (p < 0.001). We concluded that minimal invasive discectomy is good and safe treatment option for lumbar disc prolapse.

Highlights

Lumbar disc herniation is a prevalent condition and symptomatic patients present a significant socioeconomicHow to cite this paper: Jaff, H.A., Amin, B.R.M., Fatah, R.M.N. and Husein, H.H. (2016) The Outcome of Minimally Invasive Discectomy in Single Level Lumbar Disc Prolapse
Invasive techniques have the theoretical advantage of less tissue scarring and better visualization of the dura, roots and disc space, and are expected to have better postoperative outcomes [17]
Mean age of our patients with lumbar disc prolapse was 39.1 ± 9.3 years and more than half of them were ≥ 40 years age, this is goes with Grag B, et al study in India (2011) [10] whom report mean age of patients with lumbar disc prolapse as 38.7 ± 8 and Lee YG, et al study in South Korea (2010) [18] reported that high proportion of patients with lumbar disc prolapse tend to occur after 40 years of age

(2016) The Outcome of Minimally Invasive Discectomy in Single Level Lumbar Disc Prolapse. Spinal surgery in carefully selected patients who have failed conservative treatments can significantly improve quality of life [1] [2]. Better defined as sciatic neuralgia or lumbosacral radicular syndrome (LSRS), is a frequently diagnosed debilitating spine disorder with an estimated yearly incidence of 5 10 per 1000 persons [3]. The impact of low back-related disorders is quite high, as they remain the number one cause of work disability in most Western countries. Sciatica manifests itself as radiating dermatome pain regularly accompanied by diminished jerk reflexes, sensory and motor deficits [4]
