Volar fixed-angle plating of distal radius fractures: screws versus pegs--a biomechanical study in a cadaveric model.

Objectives: The purpose of this biomechanical study was to determine whether a multidirectional fixed-angle plate with locking screws or with locking pegs in the distal fragment would optimize fixation of Orthopaedic Trauma Association (OTA) type A3 distal radius fractures.

Methods: Eight pairs of fresh-frozen human distal radii were used. Extra-articular distal radius fractures were created and stabilized with a multidirectional volar fixed-angle plate.

Long-term outcome after arthroscopic meniscal repair versus arthroscopic partial meniscectomy for traumatic meniscal tears.

Background: The influence of standard meniscus treatment strategies regarding osteoarthritic progress, function, and sports activity has not been estimated in a direct long-term comparison.

Hypothesis: Meniscal repair compared with partial meniscectomy (partial meniscal resection) decreases osteoarthritic changes and reduces the effect on sports activity in the long-term follow-up.

Study Design: Cohort study; Level of evidence, 3.
