After the introduction of microsurgical techniques in the repair of peripheral nerve injury, functional restoration of the injured nerve is much improved. The authors had experienced satisfying results of operation in 5 cases of autogenous interfascicular graft and 7 cases of interfascicular anastomosis among 9 patients with peripheral nerve injury.

Acupuncture has been widely used to treat a variety of disease and symptoms. But various complications have been reported. Among them, peripheral nerve injuries have been reported less frequently than other complications. The purpose of this report is to describe what we believe to be the first case of delayed superficial and deep peroneal nerve compressive neuropathy caused by fibrotic mass formed by neglected broken acupuncture needle.

BACKGROUND: Gabapentin is widely used for the relief of neuropathic pain. But, there is no study of gabapentin in relation to traumatic neuropathic pain. The aim of this study is to assess the efficacy and effectiveness of gabapentin for the various clinical symptoms of traumatic neuropathic pain MATERIALS AND METHODS: 50 patients with traumatic nerve injury were assigned to receive gabapentin, titrated to 900 mg/day over 9 days, followed by further increases to a maximum of 2400 mg/day. Continuous pain, paroxysmal pain, allodynia and thermal evoked pain were measured in mean daily pain scores, based on the 11-point Likert scale. The primary efficacy parameter was compared from the baseline to the final study week. RESULTS: Over the 4.5 week study, this pain score decreased by 2.6 points in the continuous pain, 3.6 points in the paroxysmal pain, 3.1 points in the allodynia, and 2.5 points in the thermal evoked pain. The percentage of patients with over 50% improvement in pain scores was 33% in the continuous pain, 67% in the paroxysmal pain, 53% in the allodynia and 36% in the thermal evoked pain. There was no significant correlation between the effect of gabapentin and the time difference of the onset of symptoms and start of medication. CONCLUSIONS: This study shows that gabapentin reduced neuropathic pain in patients with traumatic peripheral nerve injury. Among the various characteristics of neuropathic pain, the reduction of paroxysmal pain and allodynia was greatest.

Quantitative analysis of abnormal spontaneous activities, motor unit action potentials and interference patterns were recorded in 55 subjects with traumatic peripheral nerve injury to understand the changes of electromyographic signals. We analyzed amplitudes of fibrillation potentials and positive sharp waves at rest, amplitude, duration, spike duration and polyphasicity of motor unit action potentials at minimal contraction, and the root mean square(RMS), and mean rectified voltage (MRV) at maximal contraction. The amplitudes of fibrillation potentials and positive sharp waves had negative correlations with the duration of peripheral nerve injury but the amplitudes of motor unit action potentials, RMS, and MRV had positive correlations. Therefore electromyographic evaluation could be used for the estimation of the duration of peripheral nerve injury.

Formation of the traumatic neuroma results from abnormal nerve regeneration following a peripheral nerve injury. Numerous treatment options have been described. However, there is no one way that is completely effective in the management of these peripheral neuromas. Prevention is best. It is important to maximize nonsurgical management, including pain management and physiotherapy. At the time of surgery, definitive neuroma resection and tension-free repair or coverage will provide the least amount of subsequent nerve irritation.

Ninety-one nerve injuries (median; 36, ulnar; 43, radial; 12) involving the upper extremity in 66 patients were studied over a twelve-month period. The results for the median, ulnar and radial nerves after nerve repair were analyzed with respect to the suture method, the age, the level of injury and the time interval from injury. The results were obtained as follows: 1. Sympathetic nerve function returned from 6 weeks (average) after operation. 2. There are better results in perineurial suture than in epineurial suture. 3. There are better results in under 16 years old than over 16 years. 4. There are better results in high level injury than in low level. 5. There are the best results in the delayed primary suture, the next in the primary suture and the last in the secondary suture. 6. Good recovery in motor function was observed in radial, median and ulnar nerve in order.
