Comparative Study
Biomechanical comparison of locking versus nonlocking volar and dorsal T-plates for fixation of dorsally comminuted distal radius fractures.
The purpose of this study was to gain insight into the effect of plate location and screw type for fixation of extra-articular distal radius fractures with dorsal comminution (Orthopaedic Trauma Association Type 23-A3.2). ⋯ No difference in all measured biomechanical parameters supports equivalence between constructs and surgeon discretion in determining operative method. Minimal fragment displacement and construct deformation during physiological testing support previous data that early postoperative motion can be recommended. Fragment displacement that occurs does so in the early periods of motion.

A divergent dislocation of the elbow is a very rare injury, and only a few cases have been described in the literature. It is characterized as a dorsal dislocation of the ulnohumeral joint combined with a lateral dislocation of the proximal radius. All three articulations of the elbow joint are involved. ⋯ After gross reduction of the joint dislocation, definitive osteosynthesis of the distal radius fracture was performed. Subsequently, the coronoid process and lateral collateral ligament could be repaired anatomically, improving the stability of the elbow. An uneventful recovery with excellent elbow motion and stability was achieved.

To investigate the usefulness of flexion and extension radiographs of the cervical spine as a screening tool for the acute evaluation of ligamentous injury in cases of awake blunt trauma in patients with a negative cervical computed tomography scan. ⋯ Flexion and extension radiographs do not appear to be clinically useful in assessing acute instability in patients hospitalized with blunt trauma with negative computed tomography scans.

This study evaluated the usefulness of a single-stage, free-fibular vascularized osteoseptocutaneous flap transfer for Type III open tibial shaft fractures with segmental bone loss for the reconstruction of combined bone and soft tissue defects. ⋯ The free fibular vascularized osteoseptocutaneous flap grafting is an effective alternative in management of Type III open tibial fractures using a one-stage procedure. The grafted fibula offers good fracture stabilization plus a vascularized bone graft, and the fibular flap can also provide a large piece of mobile skin to cover the soft tissue defect in Type III open tibial fractures. The free osteoseptocutaneous flap also serves as a visible monitor of the adequacy of the circulation of the grafted fibula.
