A controversy still exists in the management of nerve injection injury. The results of different timing of operation and methods in treating this type of nerve injury were analysed in limb s function, neuroelectrophysiology and histology. The results showed that the recovery of the injuried nerve in the group of operation, was considerably better than that in the group without operation. In the group of operation early incision of the epineurium with saline irrigation! was superior to late neurolysis. It was suggested that the early incision with saline irrigation could be used as an emergency management for this type of nerve injury.

Objective To investigate the methods and outcome of endoscopic ulnar neurolysis and minimal medial epicondylectomy in treatment of cubital tunnel syndrome with ulnar nerve subluxation. Methods Between June 2004 and June 2009, 11 cases of cubital tunnel syndrome with ulnar nerve subluxation were treated with endoscopic ulnar neurolysis andminimal medial epicondylectomy. There were 7 males and 4 females with an average age of 36 years (range, 18-47 years). All cases had numbness in l ittle finger and ring finger. The disease duration varied from 3 to 18 months (7 months on average). Nine cases had atrophy in the first dorsal interosseous muscle and hypothenar muscles. The preoperative electromyography showed that the ulnar nerve conduction velocity (NCV) were slowed down at elbow, which was (27.0 ± 1.5) m/s. Results All incisions healed by first intention, and no compl ication occurred. Eleven cases were followed up 6-37 months (19 months on average). All cases had normal sensation after 1 month of operation. The muscle strength was obviously improved in 11 cases after 3 months postoperatively (grade 4 in 7 cases and grade 3-4 in 4 cases). The postoperative electromyography showed that the NCV was obviously improved, which was (43.5 ± 9.5) m/s, showing significant difference when compared with preoperative one (P lt; 0.05). According to Amadio’ efficacy appraisal standard, the results were excellent in 7 cases and good in 4 cases. Conclusion The method of endoscopic ulnar neurolysis and minimal medial epicondylectomy has the advantages of safety, convenient manipulation, small incision, and early recovery for cubital tunnel syndrome with ulnar nerve subluxation.
【Abstract】ObjectiveTo study the application of ultrasonically activated scalpel in laparoscopic intestinal adhesion release.MethodsIntestinal adhesion release with ultrasonically activated scalpel under laparoscope was performed in 29 patients suffered from intestinal adhesive obstruction after gynecological operation. ResultsAll operations were successfully performed, and none of them converted into open surgery. Intestinal disruption occurred durring operation in 2 patients with extensive intestinal denseadhesion which were mended successfully under laparoscope. The operative duration was 30-150 min (mean 45 min). Postoperative complications such as bowel leakage, bleeding, abdominal infection were not experienced. Postoperative hospital stay was 3-7 days (mean 4 days). No case had relapse symptom such as abdominal distention or pain after 1-24 months of followup. ConclusionCompared with electric scalpel, ultrasonically activated scalpel can improve the operative safety, lessen tissue damage, shorten operative time, and reduce the chance of relapse in laparoscopic operation in gynecology.
Objective To evaluate the safety and efficacy of the operation performed under the video-assisted thoracoscope to release the anterior part of the spine of the patient with severe adolescent idiopathic scoliosis (AIS). Methods From April 2004 to July 2006, 24 patients with AIS (Illness course, 1.5-9 years; Lenke Ⅰ in 17 patients, Lenke Ⅱ in 7; right scoliosis in 22, left scoliosis in 2), among whom there were 9 males and 15 females, with an average age of 14.7 years (range, 11-21 years) at the time of the operation. Before operation, the thoracic vertebral Cobb anger at the coronal plane was averaged 78.3°(range, 65-125°). All the patients had normal muscle strength and muscle tension in their lower limbs, but 5 of the patients had a decrease of the superficial sensation in their lower limbs. All the patients had a moderately or severely decreased lung reserve function. Under general anesthesia, the patient was placed in the lateral position to set up a work channel for thoracoscopy. The releasing of the thoracic intervertebral space and the confluence of the bone grafts were performed. During Stage Ⅰ or Stage Ⅱ, the orthopedic procedures for the posterior part of the scoliosis spine, the internal fixation, and the confluence ofthe bone grafts were completed. ResultsAll the patients survived the periodof perioperation. During operation, there was a hemorrhage of 50-200 ml, averaged 100 ml, with a postoperative thoracic closely-drained fluid of 100-150 ml. The incision was healed by the first intention. Each patient underwent the releaseof 4-6 intervertebral spaces, with an average of 5.5 spaces released. The average coronal Cobb angle was 45.6°(range, 25-75°). The physiological curvatureat the sagittal plane was normal, with an improved shape of the spine. The follow-up for 3-18 months averaged 9.3 months revealed that the bilateral pulmonary markings were clear, with confluence of the orthopedic segment of the spine. The patients could live and work normally, and had a significantly-improved psychological condition and an active social participation because of their improved appearance. Conclusion The releasing of the anterior part of the spine under the video-assisted thoracoscope can effectively release the adolescent idiopathic scoliosis and improve the flexibility of the spine, with a smaller degree of the surgical wound and a faster and clearer exposure of the spinal column during operation.
Objective To evaluate pulmonary function changes in patients with severe scol iosis undergoing anterior release, posterior segmental fixation and fusion, and convex thoracoplasty by resecting a short length of rib. Methods FromJanuary 2006 to July 2007, 16 patients with severe scol iosis were treated with anterior release, posterior segmental fixation and fusion, and convex thoracoplasty by resecting a short length of rib. There were 6 males and 10 females with an average age of 16.9 years (range, 10-24 years). There were 1 case of Lenke 1 curve, 9 cases of Lenke 2 curve, and 6 cases of Lenke 4 curve. The preoperative Cobb angle was (104.8 ± 10.9)° and the preoperative thoracic kyphotic angle was (30.0 ± 4.2)°. The preoperative height of “razor back” deformity was (5.9 ± 1.2) cm. Before operation, the actual value of forced vital capacity (FVC) was (2.04 ± 0.63) L and that of forced expiratory volume in 1 second (FEV1.0) was (1.72 ± 0.62) L. The percentage of actual values to expected ones in FVC was 70% ± 16%, and that in FEV1.0 was 67% ± 15%. All patients had pulmonary function tests before operation and 3, 6, 12, 24 months after operation. Results All wounds healed by first intention. The Cobb angle at 24-month follow-up was (53.4 ± 18.6)° and the correction rate was 49.0% ± 15.3%. The thoracic kyphotic angle at 24-month follow-up was (34.0 ± 2.4)° and the correction rate was 13.3% ± 2.2%. The height of “razor back” deformity at 24-month follow-up was (2.2 ± 0.8) cm. Compared with preoperative level, all these data showed significant differences (P lt; 0.05). At 3 and 6 months, the actual values of FVC and FEV1.0 decl ined, but no significant difference was found (P gt; 0.05). At 12 and 24 months, the actual values of FVC andFEV1.0 were close to the preoperative level (P gt; 0.05). The percentages of actual values to expected ones in FVC and FEV1.0 indicate continued improvement in pulmonary function from the postoperative 3 to 24 months follow-up. Compared with preoperative level, the percentages of actual values in FVC decl ined 19% 3 months postoperatively (P lt; 0.05) and 12% 6 months postoperatively (P lt; 0.05). The percentages of actual values to expected ones in FEV1.0 decl ined 16% 3 months postoperatively (P lt; 0.05), and 10% 6 months postoperatively (P lt; 0.05). The percentages of actual values to expected ones in FVC and FEV1.0 were close to the preoperative level 12 and 24 months after operation (P gt; 0.05). Conclusion In severe scol iosis patients who are treated with anterior release, posterior segmental fixation and fusion, and convex thoracoplasty by resecting a short length of rib, pulmonary function decreases obviously 3-6 months after operation. And it returns to the operative baseline 12-24 months after operation.
Objective To summarize the genotypes associated with Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) induced by methazolamide and to provide references for the diagnosis and treatment of SJS and TEN induced by methazolamide. Methods Databases including PubMed, EMbase, CNKI, and WanFang Data were electronically searched from database inception to September 2021. Two reviewers independently screened literature and extracted data, and then a systematic review was performed. Results A total of 18 studies involving 49 patients were included. HLA genetic testing was performed on 37 patients. HLA-B*59:01 was detected in 27 patients, HLA-C*01:02 was detected in 15 patients, and 14 patients carried both genes. Statistical analysis showed that the positive rate of HLA-B*59:01 was 73% (95% CI 0.58 to 0.88) and that of HLA-C*01:02 was 40.5% (95%CI 0.24 to 0.57). The latent time until the symptoms were observed was 14.08 ± 8.77 days, and the mean dosage of methazolamide administered was 88.95±39.45 mg/d. Glucocorticoid and immunoglobulin were the main treatments prescribed. Conclusion Methazolamide can cause SJS and TEN. As the presence of HLA-B*59:01 or HLA-C*01:02 has been reported as a genetic risk factor for these adverse drug reactions, the implementation of genetic screening can effectively reduce their occurrence. Glucocorticoid and immunoglobulin, anti-infectives, should be administered to control the symptoms.
ObjectiveTo explore the effect of spinal dural release on the effectiveness of expansive cervical laminoplasty for treating multi-segmental cervical myelopathy with ossification of posterior longitudinal ligament. MethodsA retrospective analysis was made on the clinical data of 32 patients with multi-segmental cervical myelopathy with cervical ossification of posterior longitudinal ligament who underwent expansive cervical laminoplasty and spinal dural release between February 2011 and October 2013 (group A); and 36 patients undergoing simple expansive cervical laminoplasty between January 2010 and January 2011 served as controls (group B). There was no significant difference in gender, age, disease duration, affected segments, combined internal disease, preoperative cervical curvature, Japanese Orthopaedic Association (JOA) score, and visual analogue scale (VAS) score between 2 groups (P>0.05). Postoperative JOA score and improvement rate, VAS score, posterior displacement of the spinal cord, and the change of cervical curvature were compared between 2 groups. ResultsSpinal dural tear occurred in 3 cases (2 cases in group A and 1 case in group B) during operation. Cerebrospinal fluid leakage occurred in 3 cases (2 cases in group A and 1 case in group B) after operation. The patients were followed up 12-46 months (mean, 18.7 months). At last follow-up, the JOA score and VAS score were significantly improved in 2 groups when compared with preoperative scores (P<0.05). JOA score and improvement rate of group A were significantly higher than those of group B (P<0.05), but VAS score of group A was significantly lower than that of group B (P<0.05). At last follow-up, no significant difference in cervical curvature was found between 2 groups (P>0.05); posterior displacement of the spinal cord of group A was significantly larger than that of group B (P<0.05). No reclosed open-door was observed during follow-up. ConclusionFor patients with multi-segmental cervical myelopathy with ossification of posterior longitudinal ligament, full spinal dural release during expansive cervical laminoplasty can increase the posterior displacement of spinal cord, and significantly improve the effectiveness.
