Arthroscopic Coracoclavicular Ligament Reconstruction Using Biologic and Suture Fixation

Presented in this report is a modified arthroscopic approach to acromioclavicular joint reconstruction via suture and allograft fixation. An arthroscopic approach is used to expose the base of the coracoid by use of electrocautery. After an open distal clavicle excision is performed, clavicular and coracoid tunnels are created under arthroscopic visualization as previously described by Wolf and Pennington. The myotendinous end of a semitendinosus allograft is sutured to a Spider plate (Kinetikos Medical, San Diego, CA). The tendinous end of the graft is prepared with a running baseball stitch. A Nitinol wire with a loop end (Arthrex, Naples, FL) is used to pass 2 free FiberTape sutures (Arthrex) and the leading sutures from the tendinous end of the graft through the clavicular and coracoid tunnels, exiting out the anterior portal. One of the FiberTape sutures is retrieved with a grasper and passed over the anterior aspect of the distal clavicle. The second FiberTape suture and the allograft are passed over the distal end of the resected clavicle. While the acromioclavicular joint is held reduced, the FiberTape sutures are tied to the plate and the allograft is tensioned medially until the plate is embedded against the superior surface of the clavicle. The tendinous end of the graft is secured to the superior surface of the clavicle with a Bio-tenodesis screw (Arthrex) medial to the clavicular tunnel.     

应用多孔高密度聚乙烯支架行儿童全耳再造术

目的总结20例儿童应用多孔高密度聚乙烯(Medpor)支架全耳再造术的经验,以利于提高此项手术效果。方法2000~2004年,应用该支架施行全耳再造术20例,其中左侧6例,右侧14例。残耳大小1 cm×1 cm~6.3 cm×2.0 cm。Ⅰ期再造11例(Medpor支架置入、颞浅筋膜瓣与残耳皮瓣转移加全厚皮片移植);Ⅱ期再造9例(其中耳后皮瓣扩张法2例,Ⅰ期残耳旷置、Medpor支架置入、颞浅筋膜瓣转移加全厚皮片移植,Ⅱ期耳垂、耳屏成形7例)。结果Ⅰ期愈合17例,延迟愈合3例,Ⅱ期修复5例,取出支架1例。20例中19例获随访,随访时间3月至3年。再造耳大小5.3 cm×3.2 cm~7.2 cm×5.2 cm,与健耳无明显差别;再造耳解剖轮廓显现较好,但质地稍偏硬,耳屏或耳垂需不同程度的修整。结论应用Medpor支架具有以下主要优点:⑴不造成其他部位的创伤;⑵手术时间缩短;⑶支架可与局部组织融合并稳妥固定;⑷支架无变形或吸收,组织排斥现象较少;⑸术后及随访显示,再造耳轮廓较为清晰、美观。该支架仍是目前儿童行全耳再造术较适宜的人工支架材料。     

乳房皮下切除与自体组织即刻乳房再造

目的探索乳房皮下切除与几种方法的乳房再造术，即腹直肌肌皮瓣或背阔肌肌皮瓣加乳房假体或局部皮瓣等即刻再造乳房的方法。方法选择乳腺导管内原位癌10例和巨大乳腺良性肿瘤5例，顺乳晕切口活检，病理检查确立诊断后，采用经乳腺切口行乳癌或巨大肿瘤的乳房皮下切除术，若乳癌或良性肿瘤体积较大，另于腋窝部加做顺腋下皱襞的附加切口，以便于取出切除的组织及切除乳腺的腋尾部，同时可以切取腋淋巴结行冰冻切片活检。然后，应用腹直肌肌皮瓣或背阔肌肌皮瓣加乳房假体或局部皮瓣即刻行再造乳房，充填乳房切除后的空间，仅以少量的肌皮瓣皮肤修复乳头、乳晕切除后的缺损，并在此转移皮瓣上再造乳头、乳晕。结果经过多专科协作共完成15例，随访结果良好，无肿瘤复发。此法再造的乳房易与健侧乳房对称，保留了原有乳房皮肤的良好感觉，外观形态自然，再造乳房瘢痕较少，且手术切口瘢痕隐蔽。结论在严格选择手术适应证防止乳腺癌复发的前提下，乳房皮下切除与即刻乳房再造法，对乳腺导管内原位癌和巨大乳腺良性肿瘤患者I期完成肿瘤切除和乳房再造术，具有积极有效的意义。
