Treatment of painful peripheral neuroma by vein implantation.

Painful neuromas form on cutaneous nerves as a result of trauma, pressure, stretch or entrapment. Since the earliest descriptions of neuromas, proposed treatments have been met with poor results and controversy. The myriad of treatments described include: simple division of an affected nerve, implantation into muscle or bone, silicon sleeves and caps, repeated injection of steroids, end-to-side neurorrhaphy, medication and vein caps to name a few. Due to encouraging recent reports of treatment of painful neuromas by vein implantation, the authors describe a simple technique to achieve this surgical goal. As veins are readily accessible due to their proximity in the neurovascular bundle, they serve as a ready source for grafting. The advantages include minimisation of trauma to bone and muscle as compared with previous treatment techniques and the relative ease of the method.

Posterior femoral cutaneous nerve entrapment neuropathy: operative exposure and technique.

An isolated posterior femoral cutaneous nerve lesion is rare. There have been seven reported cases to date. We report a 51-year-old male with pain in the posterolateral thigh, atypical from the classic anatomical description. Somatosensory evoked potentials were suggestive of a posterior femoral cutaneous nerve lesion. We describe our operative exposure and technique for decompression of the posterior femoral cutaneous nerve and include a comparative anatomical explanation for the unusual area of our patient's pain.

Lumbar discectomy and the diabetic patient: incidence and outcome.

Medical records of 363 patients who had a diagnosis of lumbar disc disease and were managed by a posterior approach lumbar discectomy over a 7 year period were reviewed: 33 patients had a preoperative diagnosis of diabetes, an incidence in this patient population of 9.1%. The results for these 33 patients who had a diagnosis of diabetes mellitus were compared with those of 33 age and sex matched nondiabetic (control) patients who had a similar operative approach. Twenty-five of the diabetic and 28 of t he control patients were available for long term follow up. The results were positive (good to excellent) for 24 of the 28 (86%) control patients and 15 of the 25 (60%) diabetic patients. Seven of the 25 (28%) diabetic patients had reoperation for recurrent disc herniation at the same level following the initial procedure compared with one of the 28 (3.5%) control patients.

Outcome following anterior cervical discectomy in compensation patients.

This is a retrospective study aimed to analyse the clinical outcomes of patients following anterior cervical decompression and fusion for radiculopathy in worker's compensation, third party and non-compensable group. The outcome of 224 cases operated between 1991 to 1998 were analysed. Only patients with radiculopathy due to a cervical disc protrusion and spondylosis were included. There were 140 non-compensable patients, 58 worker's compensation and 26 third party. There was no statistical difference in radiological fusion between the three groups (P=0.46). The worker's compensation and third party claimant groups, had an 'excellent' outcome at 65% and 69% respectively, compared to the non-compensation group at 79% (P=0.042). Rates of poor outcome were high in the worker's compensation group (9%) compared with third party (4%) and the non-compensable group (5%). Financial incentives seem to significantly influence the outcome of cervical disc surgery in our patient population.

Traumatic middle cerebral artery occlusion: case report and review of pathogenesis.

Traumatic occlusion of the middle cerebral artery (MCA) is a rare cause of cerebral infarct. We describe a case of MCA occlusion following blunt head trauma. The literature reports some 65 cases of MCA occlusion following non-penetrating blunt trauma to the head. Arterial dissection, cerebral vasospasm and thrombosis have been some of the theories discussed in the pathogenesis of this condition. We review the pathogenesis based on anatomy of the M1 segment.

Intradiploic hematoma after skull fracture: case report and literature review.

BACKGROUND: Intradiploic hematoma of the skull was first reported in 1934. The pathogenesis of this lesion is unclear. It is a very rare benign reactive process occurring after minor head trauma, with only seven cases reported in the literature to date. CASE DESCRIPTION: A 3-year-old right hand dominant male presented with a non-tender parietal scalp swelling of a 1-year duration. History included a skull fracture located in the same region 24 months before presentation. Neurological examination was unremarkable. Pathological examination after curettage of the lesion revealed features consistent with organizing hematoma. CONCLUSIONS: The pathology of chronic diploic hematoma mimics aneurysmal bone cyst, giant cell tumor, giant cell reparative granuloma, fibrous dysplasia, eosinophilic granuloma, intradiploic epidermoid and dermoid cyst, cavernous hemangioma, circumscribed osteomyelitis, and tuberculous granuloma. Chronic diploic hematoma is a lesion that must be differentiated from various skull lesions both radiologically and histologically as it is amenable to treatment with a complete cure once excised.

Clinical factors and the size of the external callus in tibial shaft fractures.

The influence of clinical factors on external callus formation was investigated by prospectively studying 50 closed adult unilateral tibial shaft fractures. The fractures were treated by closed methods and all united normally within 20 weeks of injury. The callus volume and a quantitative index of size, calculated from roentgenograms, did not correlate with clinical factors such as severity of trauma, interval from fracture to weight bearing, fracture morphology, presence or absence of a fracture gap, or fracture displacement.
