Periprosthetic femoral fractures treated with a long-stem cementless component.

Periprosthetic femoral fractures can be a difficult management problem. Proximal femoral fractures with a loose component are managed best with revision arthroplasty. We reviewed the midterm follow-up of 14 proximal femoral fractures managed with a long-stem extensively porous-coated femoral component.

Femoral strut allografts in cementless revision total hip arthroplasty.

One hundred thirteen cases of cementless femoral revision total hip arthroplasty using either cortical strut or proximal calcar allografts were reviewed for radiographic incorporation at an average 4.75 years after operation. All cortical strut grafts were used to supplement the host bone after achieving stable femoral fixation by a tight distal diaphyseal fit.

Radiocarpal articular contact characteristics with scaphoid instability.

The relative importance of the three major periscaphoid ligament complexes in maintaining the normal radiocarpal articulation was assessed. Pressure-sensitive film recorded the changes in radioscaphoid and radiolunate articular contact that occurred with sequential ligament sectioning in 12 cadaver wrists. Alterations in the radiocarpal articular contact as a result of ligament disruption are evident in the absence of the recognizable static x-ray changes of carpal instability.
