The purpose of this study was to compare the biomechanical properties of four volar fixed-angle fracture fixation plate designs in a novel sawbones model as well as in cadavers. Four volar fixed angle plating systems (Hand Innovations DVR-A, Avanta SCS/V, Wright Medical Lo-Con VLS, and Synthes stainless volar locking) were tested on sawbones models using an osteotomy gap model to simulate a distal...
Between 1994 and 2004, seven patients (nine thumbs) at our institution were treated for trigger thumb with hyperextensible metacarpophalangeal (MP; >60°) anomaly with surgical release of the A1 pulley and proximal advancement of the MP volar plate. There were four girls and three boys (three right, two left, and two bilateral thumbs) with a mean age at surgery of 46 months (range, 26 to 82 months)...
We report the incidence of late onset post-operative carpal tunnel syndrome (late carpal tunnel syndrome) and late median nerve neuropathy after volar plating of distal radius fracture by conducting a retrospective study on volar plating for distal radius fracture performed during 2002 to 2006. Two hundred eighty-two volar plating were performed for acute distal radius fracture after exclusion. Post-operative...
Post-traumatic hyperextension instability of the proximal interphalangeal joint may lead to pain, difficulty with initiating finger flexion, and a swan-neck deformity. Most techniques to correct a traumatic hyperextension deformity of the proximal interphalangeal joint require a window in the flexor retinaculum, retraction of the flexor tendons, and manipulation of the joint capsule with a conceivable...
Background The purpose of this study was to assess the extent to which a supplemental radiographic view increases accuracy and confidence ratings when determining screw placement in volar plating of distal radius fractures for evaluators of different specialties and experience levels. Methods Thirty-four distal radius fractures treated with volar plate fixation were imaged using standard AP and...
Background The irregular nature of the dorsal surface of the distal radius makes it difficult to detect prominent screws with volar plate fixation for distal radius fractures using standard fluoroscopic images. This study evaluates the accuracy of a new radiographic method, the Hoya view, for the assessment of dorsal cortical screw penetration with volar plate fixation. Methods Eight cadaveric upper...
Background Sagittal plane instability of the thumb metacarpophalangeal joint is a difficult problem with numerous surgical techniques described. The purpose of the study is to demonstrate a technique in which a distally based extensor pollicis brevis tendon autograft is utilized to reconstruct the deficient volar plate. Methods This is a retrospective case series of four patients who were followed...
Hypothesis Volar locking plate fixation is a common treatment method for distal radius fractures. Recently, implants have been designed with an option to use locking screws in the shaft portion of the plate. While there is a high incidence of low bone mineral density in patients who sustain fragility fractures of the distal radius, the need for locking shaft screws is not well defined. Our hypothesis...
