1/11. Peripheral nerve injury after brief lithotomy for transurethral collagen injection.Two patients with prior prostate surgery sustained peripheral nerve injuries after transurethral collagen injection for the treatment of urinary incontinence. In the first patient, brief lithotomy positioning caused a gluteal compartment syndrome and sciatic neuropathy. In the second patient, obturator neuropathy was due to leakage of collagen along the course of the obturator nerve. This is the first report of peripheral nerve injury in patients undergoing transurethral collagen injection.- - - - - - - - - - ranking = 1keywords = nerve injury, injury (Clic here for more details about this article) |
2/11. The value of MR neurography for evaluating extraspinal neuropathic leg pain: a pictorial essay.SUMMARY: Fifteen patients with neuropathic leg pain referable to the lumbosacral plexus or sciatic nerve underwent high-resolution MR neurography. Thirteen of the patients also underwent routine MR imaging of the lumbar segments of the spinal cord before undergoing MR neurography. Using phased-array surface coils, we performed MR neurography with T1-weighted spin-echo and fat-saturated T2-weighted fast spin-echo or fast spin-echo inversion recovery sequences, which included coronal, oblique sagittal, and/or axial views. The lumbosacral plexus and/or sciatic nerve were identified using anatomic location, fascicular morphology, and signal intensity as discriminatory criteria. None of the routine MR imaging studies of the lumbar segments of the spinal cord established the cause of the reported symptoms. Conversely, MR neurography showed a causal abnormality accounting for the clinical findings in all 15 cases. Detected anatomic abnormalities included fibrous entrapment, muscular entrapment, vascular compression, posttraumatic injury, ischemic neuropathy, neoplastic infiltration, granulomatous infiltration, neural sheath tumor, postradiation scar tissue, and hypertrophic neuropathy.- - - - - - - - - - ranking = 0.0005157052723066keywords = injury (Clic here for more details about this article) |
3/11. Complete sciatic nerve palsy after open femur fracture: successful treatment with neurolysis 6 months after injury.Although relatively uncommon, peripheral nerve can be injured secondary to fracture or dislocation. As therapeutic strategies may vary with the status of the nerve involved, accurate diagnosis is critical. The case described in this report involves a complete sciatic nerve palsy occurring after an open femur fracture treated 6 months earlier. The palsy was erroneously attributed to ischemic neuropathy from compartment syndrome, but late surgical exploration showed that the sciatic nerve was in continuity but enveloped by scar. Neurolysis resulted in full motor and sensory recovery below the knee. Accurate interpretation of physical findings and neurophysiologic tests in the management of fractures associated with nerve injury is emphasized.- - - - - - - - - - ranking = 0.20206282108923keywords = nerve injury, injury (Clic here for more details about this article) |
4/11. Hip and pelvic fractures and sciatic nerve injury.OBJECTIVE: To investigate the influence of hip and pelvic fracture, especially acetabular fracture complicated by sciatic nerve injury on clinical features and prognosis of sciatic nerve injury. methods: From January 1987 to January 2000, 17 patients (14 male and 3 female) who had hip and pelvic fractures complicated by sciatic nerve injury were treated with operative reduction and internal fixation and followed up from 10 months to 5 years. The average age was 38 years (ranging 23-56 years). The left extremities were involved in 11 patients and the right in 6. Twelve patients underwent primary exploration and neurolysis and 5 patients underwent secondary operation. RESULTS: Preoperatively, 8 patients were treated with large doses of oral narcotics to control their severe sciatic pain. Three of the 8 patients underwent patient-controlled analgesia and epidural analgesia. After operation, excellent and good rates of reduction and functional recovery of sciatic nerve were 94.1% and 88% respectively. Four patients still had sciatic pain and 2 patients failed to recover. sciatic nerve function improved within 3-6 months after surgery in 11 patients. CONCLUSIONS: Hip and pelvic fractures can result in sciatic nerve injury, especially common peroneal nerve injury and prognosis is poor. Open reduction and internal fixation combined with nerve exploration and neurolysis should be used as early as possible for severe sciatic pain.- - - - - - - - - - ranking = 1.8keywords = nerve injury, injury (Clic here for more details about this article) |
5/11. Newborn with an open posterior hip dislocation and sciatic nerve injury after intrauterine radiofrequency ablation of a sacrococcygeal teratoma.Advanced prenatal ultrasonography techniques have allowed for better understanding of the natural history, treatment, and prognosis of sacrococcygeal teratomas. Several intrauterine surgical techniques to debulk the tumor when fetal and maternal life are in jeopardy have been described. Orthopaedic impairment, such as lower extremity weakness and swelling, also has been described in association with sacrococcygeal teratomas. The authors report on a newborn in whom a large soft tissue defect overlying the posterior hip region with direct exposure of the disarticulated hip joint existed at the time of birth, which resulted from intrauterine radiofrequency ablation of a sacrococcygeal teratoma. This unexpected complication has resulted in a loss of sciatic nerve function, malformation of the acetabulum and femoral head, and loss of the left ischium, coccyx, inferior sacrum, gluteal, adductor and piriformis muscles, and posterior hip capsule. At 16 months of age, the patient has a flaccid left lower extremity with a hypoplastic hip joint.- - - - - - - - - - ranking = 0.8keywords = nerve injury, injury (Clic here for more details about this article) |
6/11. sciatic nerve injury following hamstring harvest.Injury to the sciatic nerve following harvesting of the medial hamstring tendons is a complication that has not been described. I report a unique case of sciatic nerve injury above the level of its bifurcation into its terminal branches following hamstring graft harvest for use in ACL reconstruction. The sciatic nerve anatomy and technique of graft harvest is briefly described.- - - - - - - - - - ranking = 1keywords = nerve injury, injury (Clic here for more details about this article) |
7/11. A sciatic nerve lesion secondary to compression by a heterotopic ossification in the hip and thigh region--an electrodiagnostic approach.A sciatic nerve lesion secondary to compression by a heterotopic ossification is rare. Operative release of the encased sciatic nerve in some cases may restore the function of the nerve partially or completely. However, in some cases the injury may be permanent. An electrophysiologic study is very useful to determine the location and severity of nerve damage, including axonal loss, demyelination, or both. An electrophysiologic study can emphasize the portion of the sciatic nerve that has been involved the most (lateral versus medial or peroneal versus tibial). In some cases an electrophysiologic study can suggest whether surgery should be postponed if a recovery pattern from the nerve injury is obvious. The prognostic value of follow-up studies is considerable. The authors reviewed literature available to them since 1971 and found 6 cases, including their own. This is the first attempt to put together all the information available in the literature about this condition.- - - - - - - - - - ranking = 0.20051570527231keywords = nerve injury, injury (Clic here for more details about this article) |
8/11. Neurovascular compression following isolated popliteus muscle rupture: a case report.This case report concerns an unusual complication of neurovascular compression following an isolated popliteus muscle rupture. A 59-year-old man, after a fall from a horse, gradually developed symptoms of a swollen leg, dysesthesias in the sole of his foot, and muscle weakness of his toe flexors. At presentation, he was found to have a complete tibial nerve injury at the level of the popliteal fossa and significant neuropathic pain. MRI demonstrated a rupture in the muscular portion of the popliteus muscle with extensive edema and hemorrhage compressing the tibial nerve in the popliteal fossa. The edema extended up to the distal part of sciatic nerve where there was evidence of intraneural hemorrhage. In the course of recovery, the patient additionally developed deep venous thrombosis in the ipsilateral popliteal vein. Spontaneous recovery was documented on serial clinical and electrodiagnostic examinations. The patient's neuropathic pain improved significantly within 6 months and his neurologic function recovered nearly fully by 2 years.- - - - - - - - - - ranking = 0.2keywords = nerve injury, injury (Clic here for more details about this article) |
9/11. A case of sciatic neuropathy after caesarean section under spinal anaesthesia.We present a rare case in which a healthy parturient developed a left sciatic neuropathy after spinal anaesthesia for caesarean section. Intraoperatively, a wedge was placed under her right buttock to tilt the pelvis and uterus to the left, to minimise aortocaval compression. Postoperatively, she complained of being unable to move her left foot. neurologic examination revealed a left lower leg paresis. electromyography showed denervation potentials on muscles innervated by left sciatic nerve. Seven weeks after surgery the patient had made a full recovery. We conclude that the prolonged lateral tilt position might cause compression neuropathy of the sciatic nerve. After childbirth, re-positioning the patient supine or shortening the time of lateral tilt may reduce the risk of sciatic nerve injury.- - - - - - - - - - ranking = 0.2keywords = nerve injury, injury (Clic here for more details about this article) |
10/11. sciatic nerve injury following intramuscular injection: a case report and review of the literature.A 25-year-old male patient presented with foot drop indicative of a sciatic nerve injury following gluteal intramuscular (IM) injections. blood tests and magnetic resonance imaging of his spine were within normal limits, but electrophysiological studies confirmed a partial sciatic nerve lesion. The course of the sciatic nerve in the gluteal region places it at risk for injury from IM injections. Proper technique minimizes the risk of injury.- - - - - - - - - - ranking = 1.0010314105446keywords = nerve injury, injury (Clic here for more details about this article) |
