extensor Tendon Rupture After Internal Fixation of a Distal Radius Fracture Using a Dorsally Placed Ao/asif Titanium Pi Plate

Extensor tenosynovitis has been reported as a complication of the Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation (AO/ASIF) pi plate. The authors present a case of extensor tendon rupture after internal fixation with a pi plate after one of the screws in the distal limb loosened. This mechanism of extensor tendon rupture has not been reported previously. With appropriate prevention, monitoring, and intervention this complication could have been avoided. Schnur DP, Chang B.

Treadmill injuries to the upper extremity in pediatric patients.

Injury is the leading cause of preventable death and disability in childhood and early adulthood. Approximately 25,000 children are injured on exercise equipment each year. Although hand injuries sustained on stationary bicycles in the home have been well documented, little has been reported on home treadmill injuries. Between September 1996 and March 2000, the authors treated 12 children at The Children’s Hospital of Philadelphia for injuries to the upper extremity sustained on a treadmill. The age at the time of injury ranged from 14 months to 7 years, with a median age of 2.4 years. Average length of follow-up was 11.4 months. Ten of the 12 children sustained partial- or full-thickness burns to the volar aspect of the hand and digits. Overall, 6 patients required surgical repair. A total of 25% of the volar flexion creases involved required surgery. All patients had good functional results. The authors discuss the mechanism of injury, management, and measures to prevent treadmill injuries to children. To their knowledge, this is the first report of such injuries resulting from the use of a treadmill.

Ultraviolet-assisted punch biopsy mapping for lentigo maligna melanoma.

Lentigo maligna melanoma (LMM) accounts for a substantial incidence of all locally recurrent melanoma. In addition, the head and neck area accounts for 60% to 90% of all LMMs, which has important functional and cosmetic implications. The difficulty in the identification of the true borders of LMM may account for the high incidence of local recurrence. The purpose of this study was to evaluate the efficacy of ultraviolet-assisted punch biopsy mapping to identify clear margins using identified, 2-mm circumferentially arranged punch biopsies at the junction of the pigmented and nonpigmented borders. A retrospective chart review of 20 patients with biopsy-confirmed LMM of the head and neck was performed. Using ultraviolet identification, 2-mm circumferentially arranged biopsy specimens were obtained and sent for formal pathological review, including immunohistochemical staining. The average time for completion of pathological review was 5 to 7 days. If the punch biopsies were positive for lentigo maligna or LMM, punch biopsies were obtained more peripherally. Once clear, margins were obtained and definitive resection was performed. Twenty patients with biopsy-proved LMM were evaluated. Follow-up ranged from 6 months to 3 years (mean follow-up, 1 year). Fourteen patients were cleared after their first series of biopsies, 3 patients required a second series of biopsies, 2 patients required a third session, and 1 patient required a fourth biopsy session. To date, there has been no evidence of recurrence. No patients required reexcision for positive surgical margins. One complication has been local cellulitis of a punch biopsy site requiring a short course of antibiotics. Ultraviolet-assisted punch biopsy mapping of LMM is a safe, well-tolerated, and accurate technique for identifying the true histological margin of LMM. The procedure reduces the need for repeat surgical excisions to obtain clear margins and may decrease the risk for recurrence by mapping accurately the true histological margin.

Pulsed irrigation of extremity wounds: a simple technique for splashback reduction.

Although blood and body fluid exposures are daily events often assumed to be unavoidable by operating room personnel, the potentially lethal consequences of blood-borne pathogen transmission demand preventive measures to minimize contamination risk. The authors outline a simple technique of extremity irrigation that uses a clear plastic isolation drape, pulsed lavage equipment, and surgical suction. They have found that this technique allows for thorough irrigation of wounds while providing optimal barrier protection.

National Institutes of Health Funding in Plastic Surgery: A Crisis?

Background: Decreasing funding rates and increasing competition for National Institutes of Health research grants have prompted diverse interventions in various fields of biomedicine. Currently, the state of National Institutes of Health funding for plastic surgery research is poorly understood. The purpose of this study was to describe the portfolio of National Institutes of Health grants in academic plastic surgery. Methods: Plastic surgery faculty at integrated and independent programs were queried individually in the National Institutes of Health RePORTER database for grants awarded in 2014. Funding totals, mechanisms, and institutes were calculated. Abstracts were categorized by research type and field of interest. Characteristics of National Institutes of Health–funded principal investigators were elucidated. Results: Eight hundred sixty-one academic plastic surgeons at 94 programs were queried, and only 18 investigators (2.1 percent) were funded at 12 programs (12.8 percent). National Institutes of Health–funded investigators were predominately male (72 percent), fellowship-trained (61 percent), and aged 49.3 ± 7.8 years. A total of 20 awards amounted to

222,909. Costs were primarily awarded through the R01 mechanism (77.2 percent). The top three National Institutes of Health institutes awarded 72.9 percent of the entire portfolio. Funding supported clinical (41.1 percent), translational (36.9 percent), and basic science (22.0 percent) research. Craniofacial (20.5 percent), hand (18.7 percent), and breast (16.2 percent) had the greatest funding. Conclusions: Few programs and faculty drive the National Institutes of Health portfolio of plastic surgery research. These data suggest a tenuous funding situation that may be susceptible to future spending cuts. Future research is needed to identify barriers to National Institutes of Health funding procurement in academic plastic surgery.

Unusual proximal dislocation without fracture: a case report

INTRODUCTIONnQuadrimembral amputees, as patients who have lost both upper and lower extremities, may benefit greatly from hand transplantation. The objective of this study is to evaluate the indications and contraindications for transplantation in this subset of patients.nnnMETHODSnA retrospective review was conducted of five quadrimembral amputees evaluated by our program for transplantation. Information collected included age, sex, level of amputations, time since amputations, etiology, level of dependence, medical stability, psychosocial status, and the ability to tolerate immunosuppression. Indications and contraindications for transplantation were reviewed for each patient.nnnRESULTSnAll etiologies were based in extremity ischemia: three from septic shock, one from myocardial infarction, and one from drug overdose. All patients are completely dependent. Of the five patients, two needed further reconstructive surgery and two others had a history of resolved hepatic/renal insufficiency. After thorough evaluation, two patients were selected as potential transplant candidates. They demonstrated strong psychosocial support systems, a thorough understanding of hand transplantation, along with its risks and postoperative requirements. They had also completed a full regimen of rehabilitation along with prosthetic fitting and utilization.nnnCONCLUSIONSnClearance for transplantation is based on medical stability, absence of infection or systemic diseases, and strong psychosocial support systems. Contraindications for transplantation are drug dependence and noncompliant behavior. Relative contraindications include a history of hepatic/renal insufficiency which if not resolved may preclude the use of postoperative immunosuppression.

Looped Penrose Drain for Minimally Invasive Treatment of Complex Superficial Abscesses of the Hand: Innovations in Technique

The perioperative management of a patient receiving a bilateral hand transplant is presented. The anesthetic management required careful fluid administration, homeothermic temperature maintenance, and postoperative analgesia. The role of different anesthesia subspecialties is highlighted.
