BACKGROUND Symptomatic extensor tendon irritation is a frequent complication in volar plate osteosynthesis of distal radius fractures. It is typically caused by dorsal screw protrusion and overdrilling of the dorsal cortex. The use of self-drilling locking screws (SDLS) could overcome both causes. The practical applicability of SDLS depends on two prerequisites: (1) the feasibility of preoperat...

BACKGROUND Intramedullary fixation with use of a telescopic rod with a T-piece is one of the standard methods for long-bone stabilization in growing children with osteogenesis imperfecta. However, installation and removal of this device can cause substantial damage to the distal joint, which limits its use, especially in the tibia. We devised a modification of the telescopic rod system--the int...

abstract  background: reamed interlocking intramedullary nailing of the tibia is a procedure  for the treatment of a non-infected tibial non:::::union:::::. the purpose of this clinical  study was to evaluate the outcome of this method as a treatment of tibial non:::::union:::::.  methods: twenty-nine patients with non:::::union::::: after initial therapy for tibial fracture  were retrospective...

Interlocking nailing is a common surgical operation to stabilize fractures in long bones. One of the difficult parts of the surgery is how to locate the position and direction of a screw hole on the interlocking nail, which is invisible to the naked eye after insertion of the nail into the medullary canal. Here, we propose a novel two-stage targeting process using two passive magnetic devices t...

PURPOSE To assess the maximum and end torque of a fourth-generation composite humerus model with no screw inserted or with a screw inserted in the distal (subpectoral) position or proximal (suprapectoral) position. METHODS 24 large-size, fourth-generation composite humeri were randomised to the control (n=8), proximal (n=8), or distal (n=8) group. For the latter 2 groups, an 8-mm-head interfe...

1. Every screw should pass through a plate. 2. Each screw should engage a fragment on the opposite side that is also fixed to a plate. 3. As many screws as possible should be placed in the distal fragments. 4. Each screw should be as long as possible. 5. Each screw should engage as many articular fragments as possible. 6. The screws should lock together by interdigitation within the distal frag...

BACKGROUND Extensor tendon irritation is one of the most common complications following volar locking plate osteosynthesis (VLPO) for distal radius fractures. It is most likely caused by distal screws protruding the dorsal cortex. Shorter distal screws could avoid this, yet the influence of distal screw length on the primary stability in VLPO is unknown. The aim of this study was to compare 75 ...

PURPOSE To assess the clinical outcome of unreamed intramedullary interlocking nailing in open fractures of tibia, and to evaluate the incidence of complications in these open fractures as a result of the unreamed intramedullary nailing. METHODS Between June 1999 and May 2000, a total of 60 cases of open tibial shaft fractures were operated on with unreamed interlocking nails at Safdarjung Ho...

BACKGROUND Acetabular reinforcement devices (ARDs) are frequently used as load-sharing devices to allow allograft incorporation in revision hip arthroplasty with massive acetabular bone loss. The key to a successful reconstruction is robust fixation of the device to the host acetabulum. Interlocking fixation is expected to improve the initial stability of the postoperative construct. However, a...
