Anterior stabilization in the pubic symphysis separation: a mechanical testing.

Four types of commonly used instruments, 1) external fixation, 2) tension wiring, 3) tension band wiring, and 4) single superior plating, for anterior stabilization of the diastasis pubic symphysis were tested for their mechanical properties under single load to failure in cadaveric pelvis by a universal testing machine. Three directions of loading, transverse tension, vertical tension and saggital compression, were used to test each type of instrumentation. Five specimens of each fixation were used for each direction of testing. The strongest instrumentation was single superior plating. Early mobilization can be advocated in the patient after fixation with this instrument. External fixation could resist transverse and saggital compression load at an acceptable level but not the vertical load. Tension band wiring could better resist vertical load than the other directions. Tensions wiring was the weakest instrumentation and early ambulation should be avoided.

Topical analgesics for knee arthrosis: a parallel study of ketoprofen gel and diclofenac emulgel.

The clinical efficacy of the two topical analgesics, ketoprofen hydroalcoholic gel (Fastum gel) and diclofenac emulgel, for osteoarthritis of the knee was studied. There were 85 patients who underwent the trial. They were randomly allocated into 2 groups, the diclofenac group, 42 patients (4 males and 38 females) receiving the diclofenac emulgel at the painfull site four times a day for 4 weeks, and the ketoprofen group, 43 patients (9 males and 34 females) receiving the ketoprofen hydroalcoholic gel four times a day for 4 weeks at the painful knee. Golberg's knee scoring was used to evaluate the patients before the trial, at the end of the first, second and fourth weeks. The ketoprofen group had poorer a score before the trial, however, both groups had improvement in their knee functions, knee score and pain. There was no significant difference between the groups at the end of the study. There was no serious side effect in both groups. Ketoprofen hydroalcoholic gel gave persuasive results in the treatment of knee arthrosis stage I and II.
