PURPOSE This study examined the relationship between workers' judgments of responsibility for their accidents (causal attributions) and work-site avoidance after work-related injuries. METHODS Ninety-two hand-injured workers referred for psychologic treatment of posttraumatic stress and depressive symptoms were assessed for their beliefs about the(More)
MR imaging was performed through the carpal tunnel in 18 wrists of nine normal volunteers and compared with cryomicrotome sections from cadaver wrists. MR reliably imaged the flexor retinaculum and carpal bones and thus defined the borders of the carpal tunnel. In all cases the median nerve was seen as an ovoid structure of moderate signal intensity and was(More)
There has been considerable disagreement in descriptions of the SMAS. Fresh cadaver dissection, combining anatomic dissection done with the aid of the operating microscope and histologic cross section of facial tissues, was performed in 24 facial halves. Histologic preparation was made on tissue macrosections, each 10 cm in length. Consistent findings(More)
Through detailed anatomical study and latex injection of 24 cadaver legs, the blood supply to the skin overlying the gracilis muscle was examined. The proximal pedicle entered the gracilis muscle 10 +/- 2 cm below the pubic tubercle. The dissections identified both septocutaneous and musculocutaneous perforators from the proximal gracilis pedicle. These(More)
We studied the vascular relationship of the lateral arm flap to triceps tendon and muscle in 16 dissected cadaver arms. We designed composite lateral arm free flaps containing fasciocutaneous components, triceps muscle, and/or triceps tendon. Vascular communication between the lateral arm fascia and triceps tendon was negligible. In contrast, a mean of 3.6(More)
This study examined on-site work evaluations as an environmental exposure strategy to promote return to work in 15 recalcitrant patients who had failed to benefit from established methods of reducing post-traumatic stress disorder symptoms. Following the on-site work evaluation, 87% of these patients were able to use visualisation of the work setting to(More)
Rats are commonly used to study peripheral nerve repair and grafting. The traditional footprint method to assess functional recovery is messy, indirect, and not useful when contractures develop in the animal model. The aim of the present study was to establish an accurate, reproducible, but simple, method to assess dynamic limb function. The basic(More)
The nasolabial fold was analyzed by anatomic and histologic evaluation of the tissue planes that create and surround the fold. A fascial-fatty layer exists in the superficial subdermal space extending from the upper lip across the nasolabial fold to the cheek mass. The SMAS is present in the upper lip as the superficial portion of the orbicularis oris(More)
Four patients underwent microvascular transfer of a lateral arm fascial flap to salvage severely ischemic digits by means of induction of neovascularization. The cause of the digital ischemia was direct trauma (crush injury) in one patient and chronic embolic phenomena (proximal arterial occlusion) in three patients. None of the patients had responded to(More)
The mechanical strengths of five common fixation techniques for spiral fractures have been tested. A total of 240 cadaver metacarpals and proximal phalanges were fractured and fixed by either crossed K-wires, interosseous loops, a dorsal mini-plate, a single compression screw or K-wire plus cerclage wire. Specimens were subjected to torsional and cantilever(More)
