Indications and limitations of locked plating

The goal of fracture fixation is to achieve bone healing and restore the function of the injured limb in the shortest possible time without compromising safety. Newer technologies such as the locking compression plate (LCP) and its derivatives are valuable additions to the orthopaedic traumatologist's armamentarium. As with any emerging technology, the indications will be extended until a threshold is reached and the limitations of the technology are seen. It is vital that surgeons involved in fracture care are aware of when locked plating is superior to other methods and also when they should use another treatment modality.This paper reviews the use of locked plating as a fixation method. Five topics covered in this review are: a historical perspective on locked plating, general indications, specific modes and techniques, patterns of failure, and an anatomical overview of current indications for locked plating.

Partial Portal Vein Ligation Plus Thioacetamide: A Method to Obtain a New Model of Cirrhosis and Chronic Portal Hypertension in the Rat

To obtain a new model of chronic portal hypertension in the rat, two classical methods to produce portal hypertension, partial portal vein ligation and the oral administration of thioacetamide (TAA), have been combined. Male Wistar rats were divided into four groups: 1 (control; n?=?10), 2 [triple partial portal vein ligation (TPVL); n?=?9], 3 (TAA; n?=?11), and 4 (TPVL plus TAA; n?=?9). After 3 months, portal pressure, types of portosystemic collateral circulation, laboratory hepatic function tests (aspartate aminotransferase, alanine aminotransferase, bilirubin, alkaline phosphatase, and gamma-glutamyl transpeptidase) and liver histology were studied. The animals belonging to group 2 (TPVL) developed extrahepatic portosystemic collateral circulation, associated with mesenteric venous vasculopathy without hepatic destructurization or portal hypertension. Animals from group 3 (TAA) developed cirrhosis and portal hypertension but not extrahepatic portosystemic collateral circulation, or mesenteric venous vasculopathy. Finally, the animals from group 4 (TPVL?+?TAA) developed cirrhosis, portal hypertension, portosystemic collateral circulation, and mesenteric venous vasculopathy. The association of TPVL and TAA can be used to obtain a model of chronic portal hypertension in the rat that includes all the alterations that patients with hepatic cirrhosis usually have. This could, therefore, prove to be a useful tool to study the pathophysiological mechanisms involved in these alterations.     

经大隐静脉穿刺置管溶栓治疗急性期髂股静脉血栓形成

目的:探讨经大隐静脉入路置管溶栓治疗髂股静脉血栓形成的应用价值。方法:对18例急性期髂股静脉血栓形成的患者在下腔静脉滤器植入术前提下,经大隐静脉入路置管溶栓治疗。结果:18例患者经大隐静脉穿刺成功置管,技术成功率为100%,治疗有效率为100%。置管期间无不良反应及并发症发生;平均住院时间为12.5d。结论:经大隐静脉入路置管溶栓介入治疗急性期髂股静脉血栓操作简便,经济实用,安全有效。     

Traumatic Injury of the Superior Mesenteric Vein: Ligate,Repair or Shunt?

Abstract We report a case of SMV injury in a critically ill patient. The patient was a 19-year-old woman involved in a motor vehicle collision. Her injuries included grade II splenic and renal lacerations, devascularized and lacerated right and transverse colon, a transected transverse mesocolon, a massive shear injury of her abdominal wall, and two partial SMV transections. At initial damage control laparotomy, the SMV was ligated, the devascularized bowel resected and a temporary abdominal closure applied. At re-operation, a mesocaval shunt using saphenous vein was employed. The shunt failed and the patient required a saphenous vein jump graft. Although visceral vascular injuries are rare, ligation of the SMV in a damage control situation is acceptable. This case study is the first to discuss appropriate treatment when interruption to a patient's collateral visceral venous drainage limits the surgeon’s ability to ligate. In these situations, bypass shunts may be successful.     

髂深血管蒂髂骨-腹内斜肌同蒂双岛状瓣修复下颌复合组织缺损

目的评价以髂深血管为蒂的髂骨—腹内斜肌双岛状瓣（简称同蒂双岛状瓣）修复下颌复合组织缺损的临床应用价值。方法2005年1月至2006年10月,应用同蒂双岛状瓣修复10例下颌骨复合组织缺损（包括下颌骨体部、下颌角和下颌骨升支及其周围软组织,其中有7例还包含髁突的缺损）。结果10例同蒂双岛状瓣移植均获成功,仅1例出现局部轻度感染,换药后二期愈合。术后随访3～24个月,均无肿瘤复发,颌面外形两侧基本对称,咬合关系恢复正常,且供区未见明显的并发症。结论同蒂双岛状瓣具有切口隐蔽、单一,对供区功能影响小,软硬组织复合缺损同期修复效果好等特点,是半侧下颌骨复合周围软组织大型缺损功能重建的较好方案。

Percutaneous coronary intervention in two occluded arms of a saphenous 'Y'-graft: the importance of protecting both of your arms.

Percutaneous intervention in saphenous vein grafts (SVG) carries a higher risk of distal embolization than intervention in a native vessel, and use of a distal protection device has been shown to improve the outcomes in SVG interventions. We describe an intervention done in an unexpected 'Y' SVG which required dual distal protection with Filterwires placed in both limbs of the diseased graft and which was performed via a 6 Fr guide catheter.
