Comparative Study
Limb salvage for chronic tibial osteomyelitis: an outcomes study.
The decision to undergo a limb salvage procedure is difficult and multifaceted. This study reviews the outcomes of patients with chronic tibial osteomyelitis who underwent limb salvage and hopes to enhance our understanding of the impact this complex procedure has on the patient's ability to have a functional and fulfilling life. ⋯ Limb salvage seems to be a satisfactory option for patients with chronic tibial osteomyelitis. A history of smoking and advanced age may have adverse affects and are relative contraindications.

Randomized Controlled Trial Comparative Study Clinical TrialThe incidence of thrombosis in high tibial osteotomies with and without the use of a tourniquet.
In a prospective randomised study, 65 high tibial osteotomies were performed in cases of varus osteoarthritis of the knee, and the incidence of thrombosis with and without the use of a tourniquet was studied. With an average incidence of thrombosis of 10.8%, no statistically significant differences between these two groups were seen.

Comparative StudyResults of posterior cruciate-retaining unconstrained total knee arthroplasty after proximal tibial osteotomy for osteoarthritis. A prospective cohort study.
The purpose of the study was to investigate the results of posterior cruciate ligament (PCL)-retaining total knee arthroplasty (TKA) after previous proximal closed wedge tibial osteotomy for degenerative arthritis according to the technique recommended by Coventry and Insall. Thirty-five patients with previous proximal tibial osteotomy were matched to 35 patients without previous osteotomy according to age, sex, and Knee Society patient category. TKA after osteotomy was technically more difficult, often requiring a more extensive exposure. ⋯ Knee Society scores were significantly lower in those with previous osteotomy, primarily because of decreased anteroposterior stability and pain. No significant differences were found in function scores, range of motion, or alignment. However, overall results of this PCL-retaining unconstrained TKA did not match those reported after PCL-substituting TKA.

Dome-shaped proximal tibial osteotomy using percutaneous drilling for osteoarthritis of the knee.
We have improved a surgical technique for proximal tibial osteotomy that involves percutaneous drillings. We performed the modified dome-shaped proximal tibial osteotomy on 44 knees in 42 patients (8 men and 34 women) with an average age of 66 years (range 50-78 years) for osteoarthritis of the knee. The mean follow-up period was 39 months (range 24-63 months). ⋯ They were treated with AO cancellous screw fixation, and improvement of pain was obtained in both cases. Osteotomy drill guide instruments are useful for accurately performing dome-shaped osteotomy. Our proximal tibial dome osteotomy with an external fixator allowed early motion and accurately maintained the angle of correction.

Electromyographically evident changes in skeletal muscles during tibial lengthening in dogs using the Ilizarov method.
Twenty-four beagle dogs underwent a lower leg lengthening on the right side of 2.5 cm at a distraction rate of 2 times 0.5 mm per day using a circular fixator system. After a latency phase of 5 days and a distraction phase of 25 days, 12 dogs (30-day dogs) underwent electromyography (EMG) of the gastrocnemius muscle on the lengthened and on the control side. The remaining half of the dogs underwent EMG after a consolidation phase of 25 days following the end of distraction (55-day dogs). ⋯ In the 55-day dogs, no significant differences were observed in the various parameters between the lengthened and the control side. Comparing 30- and 55-day dogs, the duration of the potentials on the distraction side was not significantly shorter in the 55-day dogs, and the amplitude significantly higher. These findings could indicate combined neurogenous and myopathic alterations of the muscles during the early distraction phase which will be compensated during the later distraction period and the consolidation phase by reparative and reinnervation processes, leaving no lasting functional damage.
