Malunion is the most common complication of the distal radius with many modalities of treatment available for such a problem. The use of bone grafting after an osteotomy is still recommended by most authors. We hypothesised that bone grafting is not required; fixing the corrected construct with a volar locked plate helps maintain the alignment, while metaphyseal defect fills by itself. Prospectively, we performed the procedure on 30 malunited dorsally-angulated radii using fixed angle volar locked plates without bone grafting. At the final follow-up, 22 wrists were available. Radiological evidence of union, correction of the deformity, clinical and functional improvement was achieved in all cases. Without the use of bone grafting, corrective open wedge osteotomy fixed by a volar locked plate provides a high rate of union and satisfactory functional outcomes.

The aim of this study was to analyze the impact of various donor and machine parameters on PLT yield in 127 PLT apheresis procedures, to optimize PLT yield achieving clinical and economic advantages. One hundred and twenty-seven apheresis procedures were analyzed. Age, gender, volume processed, Hb, and PLT precounts were included as donor predicting variables. AC infusion rate, processing time, and plasma volume collected with PLTs were assessed as machine parameters. We evaluated the post-transfusion effectiveness in 23 patients with thrombocytopenia, studying the effect of PLT dose, ABO group, and PLT storage time. Females gave higher yields, compared to males, P<0.01. PLT yield correlated positively with PLT precount (r=0.512), and TBV (r=0.404), and negatively with donor preapheresis Hb (r=-0.306). Processing time and AC infusion rate had a positive impact on PLT yield. Post-apheresis decrease in PLT count was 53.6+/-26.3x10(11). Donors with Hb>or=12 g/dl, donated safely. Most of the complications were citrate related (13.4% of all procedures). PLT increments in transfused patients correlated positively with the number of units transfused (r=0.41), and negatively with PLT storage days (r=-0.342). PLT increments in patients receiving ABO-compatible PLTs were 75% higher, compared to the increments in patients receiving incompatible PLTs. PLT count and volume processed were the main predictors of PLT yield. Increasing the processing time, the AC infusion rate, or the volume of plasma obtained with PLTs can increase PLT yields. High PLT dose, short storage time, as well as ABO compatibility should be considered during PLT transfusion.

The results suggest that continuing the intake of antiplatelet drugs did not increase bleeding after placement of dental implants.

Scaphoid nonunion advanced collapse leading to wrist osteoarthritis is treated by 4-corner fusion, capitolunate arthrodesis, and 3-corner fusion with a variety of hardware and bone grafting techniques as reported in the literature. However, such procedures have been associated with complications such as nonunion, hardware failure, and deep infection. On the basis of the same concept of these intercarpal fusions with the aim to transmit the load of the wrist, we present bicolumnar fusion to fuse the capitolunate articulation and the triquetrohamate articulation and preserve the articulation between the 2 columns, maintaining much of the normal anatomy and physiology of the normal wrist. This technique has allowed the use of screws for compression of both articulations and achieve union without the use of bone grafting.
