The scope of wounds encountered in casualties from the global war on terrorism: from the battlefield to the tertiary treatment facility.

Injuries seen in Operation Iraqi Freedom range from those that can be managed with nonsurgical wound care only to those requiring amputation or multiple bony and soft-tissue procedures for limb salvage. The contamination and soft-tissue injury caused by exploding ordnance requires an aggressive treatment approach. Severe wounds treated near the battlefield (ie, level II) require meticulous surgical débridement, early fracture stabilization, broad-spectrum antibiotics, and rapid evacuation. Treatment at a level III combat support hospital involves a greater volume of patients and a longer stay because of the presence of Iraqi national patients. In the authors' experience, most US patients requiring surgical treatment were evacuated to a level IV facility (ie, Landstuhl Regional Medical Center) after one or two surgeries. The basic war surgery principles of aggressive resuscitation, early and thorough débridement, short-duration damage-control surgical procedures, and rapid evacuation were critical in our reduction of wound infection rates to below 7% for all admissions.

Extension block pinning for large mallet fractures.

PURPOSE: The purpose of this report is to review the results of displaced mallet fractures treated with an extension block pin and transarticular fixation of the distal interphalangeal joint. METHODS: We retrospectively reviewed 23 patients with 24 fractures to determine the results of treatment, time to union, range of motion, and associated complications. RESULTS: The average patient age was 24 years and the average fracture size was 40% of the joint surface. Ten patients were treated acutely (less than 10 days), 10 subacutely (10-30 days), and 3 chronically (greater than 30 days). Average time to fracture union was 35 days. At 1-year or greater follow-up evaluation the average extension loss was 4 degrees and the average flexion was 77 degrees. There were no major complications and there were 5 minor complications. Using the established outcome criteria for mallet injuries, 92% had excellent or good results. CONCLUSIONS: The results of this study showed that this surgical technique resulted in rapid fracture union with only minor complications and has excellent functional outcome based on established criteria.

Successful reimplantation of a large segment of femoral shaft in a type IIIA open femur fracture: a case report.

Segmental bone loss associated with high-energy open fractures is a difficult problem. The more perplexing and controversial problem is that faced when the extruded segment of bone is retrieved from the field and available for potential reimplantation. Here we present successful reimplantation of a 13-cm segment of meta-diaphyseal femur in a 15-year-old boy. Successful reimplantation of the fragment was attributed to the anatomic location of the injury, meticulous wound care, multiple debridements, sterilization of the extruded fragment in chlorhexidine, and the patient's age.

Extension-block pinning for treatment of displaced mallet fractures.

Mallet injuries are common in active individuals, particularly those who participate in sports such as basketball and football. Although a majority of patients with displaced mallet fractures are treated conservatively with extension splinting, their treatment is often complicated by residual loss of extension and fracture displacement secondary to unfavorable fracture biomechanics and poor patient compliance. An attractive alternative to nonoperative treatment is the minimally invasive technique of extension-block percutaneous pinning. Extension-block percutaneous pinning allows anatomic restoration of the articular surfaces and avoids the complications associated with closed treatment. The technique is easy to perform and is an effective, safe alternative to the conservative treatment of displaced mallet fractures, particularly those associated with joint subluxation.
