螺旋CT三维重建成像在先天性高肩胛症手术方式选择中的作用

[目的]探讨螺旋CT三维重建技术在先天性高肩胛症分度和手术方式选择中的作用。[方法]22例先天性高肩胛症术前应用螺旋CT对病变部位进行扫描并三维重建，测量以肩胛骨肩胛冈内侧缘为参照点，两侧肩胛骨高度差。根据测量结果依据Cavendish分度将其分类，并根据三维重建成像选择不同的矫形手术术式。[结果]本组22例病人，随访2—4年，外观及功能均有不同程度的改善，未出现神经、血管和椎体等的损伤。[结论]根据螺旋CT扫描和三维重建检查结果，术前即可直观的明确先天性高肩胛症的病变程度，相互关系，伴发畸形，患侧肩胛骨与正常对侧肩胛骨的外观差异等，便于手术操作方案的制定，避免了手术操作的盲目性，减少医源性并发症的发生。     

浮肩损伤的治疗方法选择

目的探讨浮肩损伤治疗方法的选择。方法52例浮肩损伤患者行非手术治疗15例,手术治疗37例,并对其进行回顾性对比分析。采用Herscovic i功能评估方法;影像学检查主要在肩关节正位X线片上测量盂极角(GPA)。结果48例获8个月~16年随访。非手术组:随访13例,优2例,良3例,可2例,差6例;7例GPA>20°,6例GPA<20°。手术组:随访35例,其中单纯锁骨或肩锁关节固定26例:优16例,良3例,可5例,差2例;20例GPA>20°,6例GPA<20°。肩胛颈、锁骨联合手术9例:优4例,良2例,可2例,差1例;8例GPA>20°,1例GPA<20°。结论浮肩损伤手术治疗明显优于非手术治疗,且多数病例可采取单纯固定锁骨或肩锁关节的手术方案,但对于锁骨骨折合并同侧严重移位的肩胛颈骨折宜采用联合手术治疗,以重建肩关节稳定,促进关节功能的早期康复。     

联合肩胛/肩胛旁分叶皮瓣修复严重颌颈部瘢痕挛缩

目的探讨临床应用联合肩胛/肩胛旁分叶皮瓣显微修复严重颌颈部瘢痕挛缩畸形,并重建颈部三维活动功能及轮廓外观的方法和疗效。方法2003年1月~2004年11月,收治9例严重颌颈部瘢痕挛缩畸形患者,年龄9~32岁。病程2~18年。瘢痕挛缩程度为3~4度。行瘢痕切除,对颈部挛缩组织松解复位所致软组织缺损创面采用联合肩胛/肩胛旁分叶皮瓣进行解剖分区的显微修复。分叶皮瓣范围最大分叶皮瓣为20cm×8cm~20cm×11cm,最小分叶皮瓣为15cm×4cm~15cm×6cm。结果9例患者有8例分叶皮瓣成活,1例肩胛皮瓣远端发紫,经换药加压包扎后成活。其中8例术后获3~9个月随访,畸形无复发,颌颈角恢复至90~105°;3例行二期皮瓣臃肿修整手术。患者对术后颌颈部外观和功能均满意。结论对于严重颌颈部瘢痕挛缩畸形,联合肩胛/肩胛旁分叶皮瓣可提供足够的组织覆盖,有可靠的血管蒂,对于重建颌颈部功能和外形,是一种较好的手术选择。     

Clinical significance of suprascapular nerve mobilization

The anatomy of the suprascapular nerve is important to surgeons when focal nerve lesions necessitate surgical repair. Recent experience with a patient who had a complete suprascapular nerve lesion in the retroclavicular region (combined with axillary and musculocutaneous nerve lesions) is presented to illustrate that successful direct nerve repair is possible despite resection of a neuroma. Specifically, we found that neurolysis and mobilization of the suprascapular nerve and release of the superior transverse scapular ligament provided the necessary nerve length to achieve direct nerve repair after the neuroma was removed. A combined supraclavicular and infraclavicular approach to the suprascapular nerve provided excellent visualization, especially in the retroclavicular region. Postoperatively, the patient recovered complete shoulder abduction and external rotation with the direct repair, an outcome uncommonly achieved with interpositional grafting. Based on our operative experience, we set out to quantify the length that the suprascapular nerve could be mobilized with neurolysis. Mobilization of the nerve and release of the superior transverse scapular ligament generated an average of 1.6 cm and 0.7 cm of extra nerve length respectively, totaling 2.3 cm of additional usable nerve length overall. The ability to expose the suprascapular nerve in the retroclavicular/infraclavicular region and to mobilize the suprascapular nerve for possible direct repair has not been previously emphasized and is clinically important. This surgical approach and technique permits direct nerve repair after resection of a focal neuroma in the retroclavicular or infraclavicular region, thus avoiding interpositional grafting, and improving outcomes.     

带血管蒂肩胛骨瓣植入灭活肱骨瘤段重建肩关节

目的：探讨肱骨近端恶性肿瘤切除术后带血管蒂肩胛骨瓣植入灭活瘤段骨重建肩关节的方法．方法：4例肱骨近端骨肉瘤患者(外科分期均为ⅡB)，术前均接受新辅助化疗。手术截除瘤段骨，经煮沸灭活后用带血管蒂肩胛骨瓣植入重建肩关节。结果：4例患者随访10～27个月，术后2个月ECT均显示灭活瘤段骨有核素浓聚。3例于12个月左右骨性愈合，1例术后10个月未完全骨性愈合．所有患者均无瘤生存，无局部复发和远处转移，肩关节功能均达到可接受程度。结论：带血管蒂肩胛骨瓣植入灭活瘤段骨重建肩关节手术是一种有效的肱骨近端恶性肿瘤保肢手术．具有独特的优点。
