To assess the results of a standardized staged treatment strategy for displaced open calcaneal fractures with medial wounds. ⋯ Open Type II and IIA wounds associated with displaced OTA Type 73 B or C calcaneal fractures represent high-energy injuries with potential increased risk for wound complications. In our series, a staged treatment strategy consisting of urgent débridement, provisional internal stabilization, and late definitive reconstruction offers a protocol that may reduce infections associated with open calcaneal fractures.

This article provides an overview of the biology behind the use of electrical stimulation in fracture healing and discusses the current methods of electrical bone growth stimulation. In addition, we review the best available clinical evidence for the use of electrical stimulation in the treatment of delayed and nonunions of fractures. ⋯ The other 3 meta-analyses that we identified suggested a more significant treatment effect from electrical stimulation. Although the evidence supporting electrical stimulation does trend in favor of its use to help achieve bony union, further large, multicenter, randomized, controlled trials are required to resolve the current uncertainty surrounding the use of electrical stimulation and fracture healing.

To examine the cost and efficacy of methods of general and regional anesthetic for postoperative pain control after open repair of intra-articular calcaneal fractures. We compared single-injection popliteal fossa blocks and continuous infusion popliteal fossa blocks with drug delivered through a catheter from an infusion pump (CPNB) to general or spinal anesthetic alone in terms of hospital charges, length of hospital stay, and postoperative oral and intravenous narcotic use, antiemetic use, and safety. ⋯ CPNB through an infusion pump may allow patients undergoing open treatment of calcaneal fractures to be safely discharged within 24 hours with a concomitant decrease in healthcare costs. These data suggest that this method of postoperative pain management might be applied to other patients with major foot and ankle trauma and/or reconstructive procedures and that wider use of continuous peripheral nerve blocks may lead to a reduction in healthcare costs.

Low-intensity pulsed ultrasound (LIPUS) is a relatively new technique for the acceleration of fracture healing in fresh fractures and nonunions. It has a frequency of 1.5 MHz, a signal burst width of 200 micros, a signal repetition frequency of 1 kHz, and an intensity of 30 mW/cm2. In 1994 and 1997, two milestone double-blind randomized controlled trials revealed the benefits of LIPUS for the acceleration of fracture healing in the tibia and radius. ⋯ For delayed union and nonunion, the overall success rate of LIPUS therapy is approximately 67% (humerus), 90% (radius/radius-ulna), 82% (femur), and 87% (tibia/tibia-fibula). LIPUS likely has the ability to enhance maturation of the callus in distraction osteogenesis and reduce the healing index. The critical role of LIPUS for fracture healing is still unknown because of the heterogeneity of results in clinical trials for fresh fractures and the lack of controlled trials for delayed unions and nonunions.
