BACKGROUND Femoral skeletal traction assists in the reduction and transient stabilization of pelvic, acetabular, hip, and femoral fractures when splinting is ineffective. Traditional teaching has recommended a medial entry site for insertion of the traction pin in order to minimize injury to the femoral artery as it passes through Hunter's canal. The present anatomical study evaluates the risk ...

We report a complication during total hip arthroplasty using an uncemented press-fit acetabular shell and ceramic liner for a woman with osteoarthritis. Fracture of the ceramic liner occurred during its insertion owing to non-concentric reduction. The main body of the ceramic liner became wedged in the acetabular shell and was resistant to removal. The shell itself was immovable owing to the pr...

Intramedullary (IM) pinning is a biological method of fracture fixation; but associated with complications ofpin migration, proximal fragment collapse and rotational instability. The study aimed to design double threaded(DT) IM pin evaluated its biomechanical resistance axial compression load in comparison end-threaded(ET) simple Steinman (SS) on the canine long bone gap model. DT was designedc...

OBJECTIVE To compare the biomechanical properties of a 10-hole 3.5 mm locking compression plate (LCP) with 2 proximal and 2 distal bicortical locked screws reinforced with either a Steinmann pin of 30-40% the medullary diameter or a poly-ether-ether-ketone (PEEK) rod of ∼75% the medullary diameter in a cadaveric tibia gap model. STUDY DESIGN Ex vivo study. SAMPLE POPULATION Cadaveric canine...
