Liquid dextran does not increase the elution rate of different antibiotics from bone cement.

Purpose: To investigate the possibility of increasing elution of fosfomycin, gentamicin, clindamycin, and vancomycin by the addition of dextran fluid during the cement-mixing phase.

Methods: In 12 test series, we produced standardized, antibiotic-loaded test specimens of cement, with and without addition of dextran, and determined their effectiveness against three reference pathogens in agar diffusion and elution tests.

Results: In the test series using combined agents, Refobacin(®)-Palacos(®)R plus fosfomycin continuously produced the largest zone of inhibition, both against methicillin-sensitive Staphylococcus aureus (p = 0.

Complications after total knee arthroplasty: a comprehensive report.

In most reports of complications following TKA, the method of assessment and report of complications is not defined specifically. It is thus unclear whether certain complications did not occur or were simply not assessed at all. A detailed list of possible complications following TKA was developed, and the occurence of complications in 567 primary TKAs was followed up meticulously according to this list for one year postoperatively.

Preserving the abductor mechanism in robotic THR: the influence of stem design and cutterpath.

Objective: The tip of the greater trochanter is the attachment site for the abductor muscles of the hip joint. Its preservation in robotic and conventional THR is important for normal gait. The effect of different stem designs and robotic cutterpaths on the preservation of the trochanter tip is examined.

Repetitive low-energy shock wave treatment for chronic lateral epicondylitis in tennis players.

Background: There is conflicting evidence regarding extracorporeal shock wave treatment for chronic tennis elbow.

Hypothesis: Treatment with repetitive low-energy extracorporeal shock wave treatment is superior to repetitive placebo extra-corporeal shock wave treatment.

Methods: Seventy-eight patients enrolled in a placebo-controlled trial.

The internal calcar septum and its contact with the virtual stem in THR: a computer tomographic evaluation.

The internal calcar septum is a ridge of cortical bone protruding from the inner cortical wall of the proximal femur into the medullary canal. It extends from the lesser trochanter into the femoral neck and narrows the femoral cavity in its dorsal third. This region is essential for THR stability, but the degree of contact between the septum and standard THR implants has never been studied.
