The efficacy of low-pressure lavage with different irrigating solutions to remove adherent bacteria from bone.
Recent studies have suggested that high-pressure irrigation may have adverse effects on bone. However, the use of low-pressure irrigation may not remove all adherent bacteria from bone. The type of irrigating solution may be an important factor in the removal of adherent bacteria with pulsatile lavage. In this study, we compared the effects of various irrigating solutions on the number and function of osteoblasts and osteoclasts and we examined the effectiveness of these solutions in removing adherent bacteria from bone. ⋯ Our findings suggest that certain solutions may be more effective in removing bacteria from bone than mechanical irrigation with saline solution alone. Among the various solutions examined, the soap solution preserved the number and activity of osteoblasts the most. Low-pressure lavage with the soap solution resulted in the greatest removal of adherent bacteria from bone.

Transtibial amputees from the Vietnam War. Twenty-eight-year follow-up.
The long-term functional outcome following lower-extremity amputation is not well documented. I ascertained the functional outcome and health status of patients who had sustained a unilateral transtibial amputation as a result of a battlefield injury. ⋯ Group-1 patients led relatively normal lives after sustaining a transtibial amputation in battle. The addition of another major injury (Group 2) appears to have significant long-term consequences with regard to SF-36 scores and the need for psychological care.

Proximal femoral allografts for reconstruction of bone stock in revision arthroplasty of the hip. A nine to fifteen-year follow-up.
Revision of a femoral component in a patient who has severe bone loss is a complex problem that is likely to increase with the increasing numbers of patients who have multiple revision hip arthroplasties. A valuable option in such a situation is use of a long-stem prosthesis that is cemented to a proximal femoral allograft but not to the host bone. ⋯ The clinical and radiographic results at an average of eleven years after revision hip arthroplasty with a proximal femoral allograft are encouraging. This report represents our early experience; improvements in the technique have been made. We believe that this technique provides a viable option for treatment of the difficult problem of severe femoral bone loss.
