BACKGROUND There is a dearth of detailed published work on the anatomy of ulnar artery perforators. The objective of this study was to fully document the vascular basis of the free proximal ulnar artery perforator flap and report its use in reconstruction of the hand. METHODS (1) The ulnar artery perforators were studied in 25 fresh cadavers and 10 cast preparations. Cadavers were injected wi...

 Proximal humerus fractures are common, but associated injury of the axillary artery is uncommon. The majority of published blunt traumatic axillary artery injuries are associated with anterior glenohumeral dislocation; a few are associated with isolated proximal humerus fractures or fracture-dislocation. Experience within our institution demonstrates that axillary artery injury is often unreco...

We have examined the effect of normal and uremic human sera on the transtubular flow of fluid in isolated perfused segments of rabbit proximal convoluted and straight renal tubules. Proximal convoluted and straight tubules absorbed fluid from the lumen when the external bath was normal rabbit serum. Normal human sera in the bath depressed net fluid absorption in both tubular segments, but more ...

PURPOSE The purpose of this study is to evaluate the relationship between the angle formed between the proximal most screw through the locking compression plate-proximal lateral tibia (LCP PLT) and the joint line, and to evaluate if this angle can be used intraoperatively as an assessment tool to determine normal alignment of the tibia in the coronal plane. MATERIALS AND METHODS There are two...

OBJECTIVE The purpose of this study was to compare the biomechanical properties of bicortical with unicortical screws in a proximal tibial fracture cadaveric model. SETTING Biomechanics laboratory at a Level 1 trauma center. PATIENTS/PARTICIPANTS Eight pairs (4 male and 4 female) of elderly (average age, 79 years; range, 63 to 104 years) cadaveric tibiae. INTERVENTION Osteotomies were per...

BACKGROUND Tendon disorders are common problems in sports and are known to be difficult to treat. Only limited information is available concerning treatment of proximal hamstring tendinopathy. To the authors' knowledge, no histopathologic findings of proximal hamstring tendinosis have been published. HYPOTHESIS Surgery (semimembranosus tenotomy and exploration of the sciatic nerve) is an effe...

BACKGROUND Endoprosthetic reconstruction is widely applied for pathological fractures of the proximal humerus; however, functional impairment is usually unsatisfactory. The aims of the current study are to evaluate the reliability of interlocking intramedullary (IM) nailing with cement augmentation as a fixation method in proximal humeral lesions and to assess functional outcomes. METHODS We ...
