Résumé

BACKGROUND: Lateral cutaneous femoral nerve (LCFN) injury or Meralgia paraesthetica (MP) results in restriction of activity. Compression of the nerve by disc hernia, retroperitoneal tumors, and external pressure around the anterior superior iliac spine is common. However, it is not commonly observed after lumbar spinal surgery in prone position. STUDY DESIGN: In this prospective study of 110 patients who underwent elective lumbar spinal surgery, managed from January 2002 to June 2002, the incidence, possible risk factors, etiopathogenesis and management of MP were analyzed. RESULTS: There were 66 males and 44 females. The age of the patients ranged from 15 to 81 years (mean 46.9 yrs.). Thirteen patients (12%) suffered from MP. It is more common in thinner individuals due to pressure injury to the nerve at its exit point. Ninety-two per cent of the patients were asymptomatic at follow-up after 6 months. In 7 out of 13 patients, patchy sensory loss on clinical examination was seen at 6 months. CONCLUSION: MP after posterior lumbar spinal surgery is uncommon. Smaller bolsters may avoid some of the vulnerable pressure points, as the surface area available is relatively smaller. The posts of the Hall-Relton frame over the anterior superior iliac crest should be adequately padded. The condition is usually self-limiting. Surgical division or decompression of the LCFN is reserved for persistent or severe MP.

Résumé

The dorso lumbar segment of spine (D10 to L2) is an unstable zone between fixed dorsal and mobile lumbar spine. A combined anterior and posterior approach with short segment stabilization was found most appropriate. Thirty cases were treated over a period of 4 years and 6 months. There were 26 male and 4 female patients with mean age of 32.6 years. L1 vertebra was fractured in 17 cases, D1 in 8 cases, D11 in 4 cases and D10 in one case. 14 cases had total neurological deficit, 9 cases had partial and 7 had no neurological deficit. We have used three column classification of Denis to assess the cases. Seven patients returned to regular physical work, 5 had restricted physical work, 5 remained in full time light job and 9 patients were unable to return to original job but did some work. Most had flaccid paraplegia but 4 patients were completely disabled due to spastic paraplegia. Neurological recovery occurred in all the patients with partial paralysis, and appeared to be dependent on initial kyphosis. The overall recovery rate varied from 50% to 90%. There is no correlation between canal compromise and severity of injury. Neurological injury occured at the time of trauma, rather than as a result of pressure of fragment in the canal. No strong conclusion could be drawn to say that the results of surgery were superior to non-operative treatment.

Résumé

Serial roentgenograms of 40 patients who had 70 cervical intervertebral spaces grafted with ethylene oxide sterilized cadaver bone and 28 patients who received 44 iliac crest auto grafts for anterior cervical spine fusion, were studied. The radiological evaluation was made on the basis of settlement of intervertebral spaces, fusion rate, delayed union, non-union, graft collapse and extrusion of the graft. Indigenous methodologies were designed for the assessment of settlement of grafted intervertebral spaces in percentage. Disc space settlement was more common in autografts (93% cases) than in allografts (80% cases). The average percentage of settlement of intervertebral disc space (S%) was 22 in autografts and 28 in allografts during the first four months. By the end of eight months, allograft disc spaces settle more. No significant difference was noted in fusion rate at the end of one year viz. allografts (90% cases) and autografts (93% cases). Autograft and allograft (ethylene oxide sterilized cadaver bone) are equally useful in anterior cervical spine fusions.
