Hip Arthroscopy Without a Perineal Post: A Safer Technique for Hip Distraction

Pudendal nerve palsy is a reported complication of hip arthroscopy. We report a technique using a deflated taped beanbag rather than a perineal post. The patient is placed in the supine or lateral position on a fracture table. The beanbag is contoured around the patient’s flank and thorax. The distal aspect of the beanbag is placed no further than the iliac crest, and care is taken to avoid compression of the posterior aspect of the axillary region or the posterior humerus. The molded beanbag is deflated, a blanket is positioned over the abdomen and lower thorax, and with the use of 3-in-wide cloth tape, the patient and beanbag are secured to the operative table circumferentially. The superior margin of the deflated beanbag remains firm, preventing compression of the thorax and avoiding compromised ventilation. The arm on the operative side is placed across the chest and secured to avoid obstruction of the operative field. This patient positioning provides sufficient stability for adequate traction and good visualization while minimizing the risk of a pudendal nerve palsy.

[目的] 探讨胫骨高位截骨手术并发症的发生情况，并提出预防和治疗措施。[方法]2000年1月～2004年10月采用胫骨高位截骨术治疗膝骨关节炎合并内翻畸形患者126人，21人发生手术并发症，男4例，女17例；年龄48～64岁，平均61岁。术前拍摄站立膝关节正位X线片，测量股骨一胫骨角，计算截骨角度，采用外侧闭合胫骨高位截骨术矫正膝内翻畸形。[结果] 术后随访6～12个月，平均7．5个月。共21名患者发生各类并发症23例次．发生率为16．7％。其中发生胫骨骨折4例，腓总神经麻痹3例，出现深静脉血栓形成5例，膝内翻复发病例6例，内固定失败4例（其中2例合并膝内翻复发），感染1例。[结论] 降低胫骨高位截骨手术并发症需要术者熟悉局部解剖和精确的术前设计，提高手术技巧及完善的围手术期护理。     

Non-steroidal anti-inflammatory drug (NSAID)-induced colonic strictures and perforation: A case report

Although non-steroidal anti-inflammatory drug-induced colopathy is well described, colonic perforations complicating non-steroidal anti-inflammatory drug intake are rare. We report a patient with rheumatoid arthritis who was on long-term diclofenac and presented with early colonic stricture formation and a caecal perforation, which to the best of our knowledge, has only been reported once before. It is important to suspect this diagnosis in patients on non-steroidal anti-inflammatory drug therapy who present with an acute abdomen.     

急性重度眼烧伤135例临床分析

目的了解急性重度眼烧伤的临床特点、预后及并发症发生情况。方法对笔者单位病案室保存的1977--2002年住院眼烧伤患者135例（155只眼）的病历进行回顾性统计分析。分析不同深度、原因眼烧伤的眼表修复率、修复时间、致盲情况及并发症。结果治疗后Ⅲ度眼烧伤的修复时间短于Ⅳ度眼烧伤，其修复率也明显高于Ⅳ度眼烧伤（P〈0．01）；在不能修复的Ⅳ度眼烧伤中，酸烧伤致角膜穿孔6只眼，显著高于碱烧伤（1只眼，P〈0．05）。Ⅲ度眼烧伤视力≥0．05者有38只眼，〈0．05者51只眼；Ⅳ度眼烧伤视力≥0．05者0只眼，〈0．05着66只眼。78只酸、碱烧伤眼中，52只眼致盲，致盲率为66．7％；77只热烧伤眼中，65只眼致盲，致盲率为84．4％。Ⅲ度眼烧伤的并发症发生率低于Ⅳ度眼烧伤。其中Ⅲ度眼烧伤角膜穿孔、睑球粘连的发生率（1．1％、36．O％）均显著低于Ⅳ度眼烧伤（27．3％、59．1％，P〈0．01）。在酸烧伤患者中，角膜穿孔及睑外翻的发生率（29．2％、37．5％）较高。而热烧伤患者中眼睑球粘连的发生率（53．2％）较高。结论Ⅳ度眼烧伤伤后的预后差，致盲率高。目前的治疗方法尚不能完全改善其视功能及预后，有待进一步研究。     

Dual microcatheter and guidewire snare technique for retrieval of intravascular foreign body: technical note

A transjugular snare technique was used to retrieve a stretched, residual mechanical detachable coil which extended from the cavernous sinus to the femoral vein, obliterating the transpetrosal route for further embolisation. The coil was snared by a microguidewire. Our new technique is described in this paper. Received: 19 April 1995 Accepted: 31 July 1995     

防止椎板切除术后硬脊膜外瘢痕粘连的实验研究

作者在４个平面间隔切除１１只山羊的椎板，分别用硅胶膜、自体游离脂肪片、带蒂肌肉瓣覆盖硬脊膜，一处平面作空白对照。术后４个月组织学检查，结果显示，硅胶膜后方有少许瘢痕组织增生，间质中有炎细胞灶状浸润，硅胶膜与硬膜囊无瘢痕形成，新形成的椎管后壁光滑，硬膜囊无受压；脂肪片被纤维组织取代，周围纤维组织增生轻微，形成菲薄之纤维膜，与硬脊膜容易分离；带蒂肌肉瓣周围形成较多瘢痕与硬脊膜粘连重，肌肉瓣已完全纤维化，空白组形成瘢痕最多，与硬脊膜粘连最重。术后硬膜囊矢状径以硅胶膜组最大，脂肪片组次之，带蒂肌肉瓣组再次之，空白组最小。作者认为，硅胶膜与脂肪片能明显防止椎板切除术后纤维瘢痕粘连对硬膜囊的压迫，在支架诱导作用方面，硅胶膜优于脂肪片，在生物相容性方面脂肪片优于硅胶膜。带蒂肌肉瓣优于对照组，但不及前两者。     

Alloplastic injectable biomaterials for soft tissue augmentation: a report on two cases with complications associated with a new material (DermaLive) and a review of the literature

A wide variety of biological and alloplastic injectable biomaterials are available for soft tissue augmentation, but the ideal material has not yet been discovered. Biological materials such as collagen and hyaluronan yield temporary results, while injectable alloplasts are apt to cause varying degrees of foreign body reactions that may result in lumps and chronic inflammation.We present two cases (one is the first filed case in the world) of migratory subcutaneous inflammatory masses secondary to injection of acrylic hydrogel (DermaLive), which is an alloplastic biomaterial recently introduced into the market in Europe. Histology revealed foreign body reaction to acrylic hydrogel with granuloma formation containing multinucleated giant cells. Following this, further reports on complications have been reported elsewhere in Europe. The use and development of injectable materials, as well as alternative methods and future directions are reviewed.
