Scarring is considered a major medical problem that leads to cosmetic and functional sequelae. Scar tissue is clinically distinguished from normal skin by an aberrant color, rough surface texture, increased thickness (hypertrophy), occurrence of contraction, and firmness. Marked histologic differences are the change in dermal architecture and the presence(More)
OBJECTIVE The purpose of this study was to accurately quantify three-dimensional in vivo kinematics of all carpal bones in flexion and extension and radial and ulnar deviation. DESIGN AND METHODS The right wrists of 11 healthy volunteers were imaged by spiral CT with rotational increments of 5 degrees during ulnar-radial deviation and of five of them also(More)
Radiographs of the scaphoid after injury are difficult to interpret, and bone scintigraphy is widely used to increase the accuracy of diagnosis, though many fractures suspected on scintigraphy cannot be confirmed radiologically. We have reviewed the clinical consequences, after one year, of managing suspected scaphoid fractures according to the bone-scan(More)

In these experiments the reliability of bone scintigraphy with 99mTc diphosphonate, to assess anastomotic patency and the viability of revascularized composite fibular grafts, was studied. It was shown that bone scintigraphy is very useful for the diagnosis of anastomotic patency, but only in the first postoperative weeks. Bone scintigraphy gives no(More)
Seven patients with congenital Boyd type II pseudoarthrosis of the tibia and fibula were treated with a revascularized osteocutaneous fibular graft from the contralateral side. Follow-up ranged from 20 to 96 months (mean 67 months). All patients had previously undergone major surgery (mean three operations). Union was successful in all patients although(More)
The purpose of this study was to quantify in vivo pisiform kinematics. Wrists of healthy volunteers were imaged by spiral computed tomography during ulnar-radial deviation (n = 11) and during flexion-extension (n = 5). Relative translations and rotations of the carpal bones were determined by using a 3-dimensional matching technique. The error of this(More)
A biomechanical cadaver study was performed to identify a potential bone-ligament-bone autograft from the foot for reconstruction of the scapholunate interosseous ligament (SLIL). In this study the biomechanical properties of 9 dorsal tarsal ligaments and the anterior tibiofibular ligament were investigated and compared with those of the dorsal part of the(More)
Coalition of carpal bones is relatively common. It most frequently involves the lunate and triquetrum. This finding is almost always coincidental and asymptomatic. The fusion also can be incomplete, however, resembling a pseudarthrosis, and these patients can become symptomatic. To the best of our knowledge only 6 patients with a symptomatic Minnaar type 1(More)
PURPOSE Techniques have been developed very recently with which it is possible to quantify accurately in vivo 3-dimensional (3-D) carpal kinematics. The aim of this study was to evaluate the feasibility of our novel 3-D registration technique by comparing our data with data found in the literature. METHOD The right wrists of 11 healthy volunteers were(More)
