Dorsal distraction plating of complex distal radius fractures yields good radiographic results with minimal complications. In cases of complex distal radius fractures including dorsal marginal impaction where volar plating is not considered adequate, a dorsal distraction plate should be considered as an alternative to external fixation due to reduced risk for infection and better control of volar tilt.

It is important to understand the mechanism of polymerization, mechanical properties, and environmental and temperature effects of polymethylmethacrylate.» The liquid component of bone cement comprises methylmethacrylate monomer, N,N-dimethyl-p-toluidine, hydroquinone, and possibly dye.» The powder component of bone cement contains benzoyl peroxide, beads of polymethylmethacrylate, possibly dye, zirconium dioxide or barium sulfate radiopacifier, and antibiotics. » Up to 2 g of powdered antibiotics added to a 40-g package probably does not compromise the integrity of the cement.» Preheating the implant or heating during polymerization is controversial but does not appear to strongly negatively affect the mechanical properties of the bone cement.

Background: There has been a trend towards flexible intramedullary nailing for unstable tibial shaft fractures in the pediatric population, traditionally, utilizing a 2-incision technique with passage of one nail medially and one nail laterally. Our study aims to compare a single incision approach for flexible nailing of unstable tibial shaft fractures in pediatric patients to the traditional 2-incision approach. Methods: Patients were selected for operative fixation if they had a length unstable tibial shaft fracture confirmed by fluoroscopy. Exclusion criteria included length stable tibial fractures that could undergo nonoperative treatment. Single incision technique utilized the medial incision only. Patients were monitored in the hospital for one postoperative day and followed up at 4 week, 8 week, and 12 week marks. Radiographic analysis was performed to evaluate for malunion or nonunion. Operative times, infection rates and complications were recorded and analyzed. Results: All patients achieved complete fracture healing at the 12-week follow up. There were no delayed unions, nonunions or malunions in either treatment group. Conclusions: Single medial incision for tibial flexible nails had equivalent outcomes with no difference in primary healing rate, malunion or nonunion rate when compared to the dual incision technique.
