Enhanced fracture and soft-tissue healing by means of anabolic dietary supplementation.

Background: Malnutrition is common in hospitalized injured patients. It contributes to delayed fracture-healing and increased morbidity. However, relatively little attention has been directed toward nutritional strategies for augmenting musculoskeletal recovery after a fracture.

Anterior trochanteric slide osteotomy for primary total hip arthroplasty. Review of nonunion and complications.

The radiographic results of 73 anterior trochanteric slide osteotomies were retrospectively reviewed at an average of 36 months after primary hip arthroplasty to determine the incidence of nonunion of the trochanter and complications related to trochanteric hardware. In each case, the trochanter was retracted anteriorly, with the gluteus medius and vastus lateralis muscle insertions left intact. Reattachment was performed with 2 monofilament wires or cables passed through the lesser trochanter in each case.

Repair or reattachment of the meniscus after fixation of a tibial plateau fracture.

The intact meniscus provides protection for healing of tibial plateau fractures, prevention of early posttraumatic arthritis, and maintenance of knee stability. However, tibial plateau fractures may have associated meniscal injury that may impair this function. In addition, the meniscotibial ligaments are often divided during submeniscal arthrotomy for exposure.

Vacuum-assisted closure complicated by erosion and hemorrhage of the anterior tibial artery.

We report an erosion and hemorrhage of a left anterior tibial artery associated with a vacuum-assisted closure device. To our knowledge, this report represents the first arterial erosion associated with a vacuum-assisted closure device. We estimate our patient lost 6 units of blood.

Comparison of the response of primary human blood monocytes and the U937 human monocytic cell line to two different sizes of alumina ceramic particles.

It is well recognized that wear particles derived from orthopaedic implants have the potential to induce inflammation, which may eventually lead to aseptic loosening of the artificial joint. We hypothesized that alumina ceramic particles of different sizes cause a differential cytokine response by human monocytes. To test this hypothesis a human monocytic cell line (U937) and primary human blood monocytes obtained from healthy volunteers were exposed to ceramic particles within the range known to be generated in vivo.
