PURPOSE To compare the stability of a novel, nonspanning external fixator with a standard volar locked plate for treatment of unstable distal radius fractures. METHODS A simulated, unstable, extra- articular distal radius fracture was created in six matched pairs of fresh frozen human distal radii. One of each pair was treated with a nonspanning external fixator [Mirza Cross Pin Fixator (CPX)...

PURPOSE To determine whether there were differences between plate position in patients who had postoperative flexor tendon ruptures following volar plate fixation of distal radius fractures and those who did not. METHODS Three blinded reviewers measured the volar plate prominence and position on the lateral radiographs of 8 patients treated for flexor tendon ruptures and 17 matched control pa...

UNIVERSITY OF PENNSYLVANIA ORTHOPAEDIC JOURNAL comminution. Correction to a volar tilt of 11 1/2 5 degrees has been shown to restore biomechanical function of the wrist. Prior to the use of volar locking plates, in order to restore volar tilt it would be necessary to use a dorsal approach, bone graft, and a dorsal plate. In the case discussed in this paper osteotomy and bone graft was used due ...

A case presented dysfunctional flexion of the thumb and index fingers after volar plate fixation for of distal radius fractures was diagnosed anterior interosseous nerve palsy and confirmed by 3D-CT. 3D-CT was useful to confirm the continuities of tendons, which excluded the most common complication of tendon ruptures after volar plate fixation. Also, it was superior to needle electromyography ...

Complications have often been reported in the literature after distal radius fractures treated conservatively or operatively [1-3]. Previously, the main indication for volar plating was a volar Barton or Smith fracture, but now volar locking plates are the most commonly used treatment for unstable distal radius fractures and during the last decade this method has become increasingly popular [4]...

PURPOSE To test the hypothesis that combining orthogonal fragment-specific fixation with volar fixed-angle fixation provides markedly higher interfragment stability and construct strength compared with volar fixed-angle fixation alone. METHODS Eight matched pairs of fresh cadaveric hand and forearm specimens were potted upright in cement. Flexor and extensor tendons were isolated at insertion...

Because osseous abnormalities result in distal radioulnar joint instability, a sigmoid notch osteotomy is used to restore stability. This article describes a case of distal radioulnar joint volar instability treated with sigmoid notch osteotomy of the volar rim.A 22-year-old man presented with a 9-month history of right wrist pain with volar instability after a fall, which was treated conservat...

Distal radius fractures are one of the most common injuries and this incidence is likely to increase as the aging population increases. The type of operation and implant is a matter of discussion and randomized trials and meta analyses have failed to recommend the preferred implant. Internal fixation with volar locking plate and external fixation with supplementation with K wire have been succe...

conclusions this study did not show that distal radius anatomical indices including the radial height, radial inclination, ulnar variance and volar tilt influence perilunate fracture dislocation as risk factors. background distal radius radiographic indices may play a role as risk factors in pathogenesis of kienbock’s disease, scaphoid fracture and non:union:. perilunate fracture dislocations a...

Recent reports suggest the presence of a rare fracture type for which reduction and fixation cannot be achieved with volar locking plate (VLP). In particular, it is difficult to achieve reduction and fixation with volar lunate facet (VLF) fragments present on the volar ulnar aspect of the lunate facet, because of the anatomical structure and biomechanics in this region. Herein, we report two ch...
