The effect of incisional negative pressure therapy on wound complications after acetabular fracture surgery.

The purpose of the study was to determine if the use of incisional negative pressure therapy affected the rate of wound complications after acetabular fracture surgery. Between August 1996 to April 2005, 301 patients were found to have had an operatively treated acetabular fracture. There were 235 patients who had placement of incisional vacuum-assisted closure (VAC) who had three (1.27%) deep wound infections and one (0.426%) wound dehiscence. There were 66 consecutive patients who were available in the 5 years preceding the usage of the incisional VAC who had four (6.06%) deep wound infections and two (3.03%) wound dehiscences. This is less than the published infection rate of 4% for patients undergoing operative treatment of acetabular fractures and less than the authors' rate of 6.15% in the time period before the use of the incisional negative pressure wound therapy (p=.0414). The use of incisional negative pressure wound therapy significantly decreases perioperative wound complications after acetabular fracture surgery.

Incisional vacuum-assisted wound closure in morbidly obese patients undergoing acetabular fracture surgery.

We studied the effect of incisional vacuum-assisted closure (IVAC) on wound complications (dehiscences, infections) associated with surgical treatment of acetabular fractures in morbidly obese patients (body mass index, >40 kg/m(2)). No wound complications were found in 19 consecutive patients over 5 years of IVAC use. IVAC is an attractive treatment adjunct for minimizing postoperative wound complications in morbidly obese patients undergoing acetabular fracture surgery.

Relationship between intraoperative femoral head bleeding and development of avascular necrosis after acetabular fracture surgery.

The purpose of this study was to determine whether the presence or absence of bleeding after drilling of the femoral head can be used to predict the development of avascular necrosis (AVN) after operative treatment of acetabular fractures. A computerized medical record search from 1996 to 2005 of all patients with an operatively treated acetabular fracture yielded 146 patients who had an intraoperative assessment of the vascularity of their femoral head and 72 of whom were available for a minimum of 12 months of follow-up. The average time to the development of AVN was 99.6 weeks with a range of 21-290 weeks. Eleven of the patients in the analysis eventually developed AVN. The p value is not significant at. 092. Although the difference between groups is not significant, it does appear that there is a relationship between femoral head bleeding and the development of avascular necrosis.

The long lost art of preoperative planning--resurrected?

Tibial plateau fractures are complex injuries that can affect both knee function and stability. In the past, surgeons have relied on radiographs, viewboxes, tracing paper, and scaled acetate templates to formulate a preoperative plan. With the advent of digital radiography, viewboxes, and standard radiographs are no longer routinely available. The availability of a digital format for preoperative planning has helped to address this, but fragment manipulation and implant templating are not features of most digital radiography systems. Digital surgical planning software allows for these functions thereby enabling the surgeon to formulate a preoperative plan for fracture reduction and fixation. Concomitant use of 3-dimensional (3D) imaging software permits unlimited inspection of the fracture by allowing for oblique or special views through manipulation of the software image as opposed to potentially painful positioning of the injured limb by the patient or radiograph personnel. This case report illustrates the advantages of these new software tools.
