非角度稳定性钢板固定治疗桡骨远端关节内背侧移位骨折的结果

Objective Intra-articular fractures of the distal radius in young adults comprise a distinet fracture pattern that is diffficuh to manage and associated with a high frequency of post-traumatic arthritis.Restoration of articular congruency and alignment should improve the outcome.Methods In this study we prospectively re- viewed the results of 21 consecutive cases of dorsally displaced intra-articular distal radius fractures which were treated with internal fixation after failing to achieve articular congruency with closed reduction.Results 3 patients were lost to follow-up.For the rest of 18 patients,follow-up time ranges from 18 to 75 weeks the fractures had healed with highly satisfactory radiographic and functional results.The final volar tilt averaged 4.9°;radial inclination 23.9°;radial length 14mm;and articular incongruity,0.1 mm.Wrist motion at final follow-up examination aver- aged flexion 62°,extension 60°,radial deviation 16°,ulnar deviation 27°,pronation 77°and supination 74°.Grip strength averaged 83% of the uninjured side.The overall outcome of 18 patients(94.4%)had a good or excellent result according to the system of Gartland and Werley and 18 patients(72.2%)had a good result according to the modified system of Green and O'Brien at the most recent evaluation.The only complication in this series was a superficial pin tract infection,which was rapidly resolved with removal of pins at 5th week of external fixation. Conclusion Thus restoration of articular congruency and alignment is possible with minimal complication using modern non-angular stable methods of internal fixation.     

肘关节脱位与肱骨远端关节内骨折

Objective To describe dislocation of the elbow with articular fracture of the distal humerus,a type of elbow fracture-dislocation about which little has been written.Methods Four patients with a dislocation of the elbow and fracture of the distal humerus were identified.Three had dislocation and complex intraarticular fracture of the capitellum,trochlea,and lateral epicondyle.Results Two patients(one treated with a second operation to address avascular necrosis of the capitellum)achieved a functional arc of elbow motion and one patient was lost after removal of the implants 3 months after fracture with documented healing.The fourth patient had a complex open fracture dislocation involving the entire articular surface.An attempt to salvage the articular surface resulted in deep infection.Extensive heterotopic bone led to arthrodesis of the elbow.Conclusions Dislocations of the elbow with articular fracture of the humerus are uncommon.Most injuries involve the capitellum,lateral trochlea,and lateral epicondyle.Open reduction and internal fixation of the distal humerus fracture can restore stability without repairing the medial collateral ligament.     

Partial resection of distal humerus and reconstruction using autogenous iliac bone graft

Use of a Strecker oesophageal stent in the treatment of benign oesophageal stricture

The use of self-expanding prostheses in the management of malignant oesophageal strictures has become well established. The majority of benign peptic oesophageal strictures can be successfully managed using endoscopic or fluoroscopically guided balloon oesophageal dilatation combined with long-term drug therapy, particularly using proton pumper inhibitors. Although endoscopic oesophageal dilatation can be performed on an outpatient basis, it requires repeated hospital visits. There is a small risk of oesophageal perforation whilst cardio-respiratory complications may be encountered during the use of intravenous sedation in an elderly population. The use of a self-expanding Strecker stent in a 98 year old woman with a benign oesophageal stricture is described.     

内镜下切断屈肌支持带远侧纤维束治疗腕管综合征

目的探讨内镜下腕管切开减压术（endoscopic carpal tunnel release，ECTR）中切断屈肌支持带远侧纤维束（distal holdfast fibers of the flexor retinaculum，DHFFR）的必要性。方法观察组16例，臂丛神经阻滞麻醉，不使用止血带，皮肤1cm切口，内镜下应用USE系列切断腕管横韧带和DHFFR，与对照组16例单纯切断腕管横韧带进行疗效比较。结果术后6个月功能随访，按照Kelly疗效评定标准，观察组优13例，良3例；对照组优8例，良5例，可3例，2组浜田Ⅱ、Ⅲ级疗效差异有显著性（，=6．278，P=0．043）。2组均无严重并发症及术后复发。结论对浜田Ⅱ、Ⅲ级腕管综合征者术中注意腕横韧带切断不是唯一的目标，同时切断DHFFR才能彻底减压。     

微创经皮钢板骨桥接术联合锁定加压钛板治疗胫骨远端骨折

目的探讨微创经皮钢板骨桥接术（minimallyi nvasive percutaneous plate osteosynthesis，MIPPO）联合锁定加压钛板（locking compression plate，LCP）治疗胫骨远端骨折的近期疗效。方法2004年6月～2006年3月采用MIPPO联合LCP治疗胫骨远端骨折16例，AO分型：43A1型7例，43A3型5例，43B1型2例，43C3型2例。采用3种方法复位胫骨骨折后插入LCP，用锁定螺钉固定。结果16例随访5～20个月，平均11，5月。16例切口一期愈合，骨折无延迟愈合、畸形愈合、断钉、断板等并发症。术后X线检查4～12周（平均7．6周）骨痂形成并开始部分负重，8～20周骨性愈合（平均16周），此时开始完全负重。3例出现胫骨远端内植物局部不适。根据美国足踝骨科学会评分系统对踝关节功能评分，优14例（87．5％），良2例（12，5％）。结论MIPPO具有创伤小、固定牢靠、可早期功能锻炼等优点，近期疗效满意，是治疗胫骨远端骨折的有效方法。     

Selective Use of Older Adults in Right Lobe Living Donor Liver Transplantation

Many centers are reluctant to use older donors (>44 years) for adult right-lobe living donor liver transplantation (RLDLT) due to concerns about possible increased morbidity in donors and poorer outcomes in recipients. Since 2000, 130 adult RLDLTs have been performed at our institution. Recipients were divided into those who received a right lobe graft from a donor ≤age 44 (n = 89, 68%; median age 30) and those who received a liver graft from a donor age >44 (n = 41, 32%; mean age 52). The two donor and recipient populations had similar demographic and operative profiles. With a median follow-up of 29 months, the severity and number of complications in older donors were similar to those in younger donors. No living donor died. Older donor allografts had initial allograft dysfunction compared to younger donors. Complication rates were similar among recipients in both groups but there was a higher bile duct stricture rate with older donor grafts (27% vs. 12%; p = 0.04). One-year recipient graft survival was 86% for older donors and 85% for younger donors (p = 0.95). Early experience with the use of selected older adults (>44 years) for RLDLT is encouraging, but may be associated with a higher rate of biliary complications in the recipient.
