Flap Closure of Spinal Defects in High-Risk Patients: A 10-Year Institutional Experience.

BACKGROUND: Complication rates after spinal surgery are high, in part because of surgical advancements that have made procedures available to a broader range of medically complicated patients. The high rates of infection, hematoma, and dehiscence resulting in open wounds after spinal surgery often warrant plastic surgery involvement. In this study, we aim to examine the effects of preoperative and operative risk factors on complication rates, reoperation rates, and hospital length of stay after flap reconstruction of spinal defects. METHODS: A retrospective review was performed of 373 patients who required flap reconstruction for spinal wound closure at our institution between 2003 and 2013. Data regarding demographics, comorbidities, operative variables, and postreconstructive course were collected. RESULTS: Of the 373 patients, 97.3% had at least 1 comorbid condition associated with poor wound healing, 91.2% had a significant wound condition at the time of reconstruction, and 81.8% had a history of 2 or more spinal surgeries. After reconstruction, average hospital stay was 14 days, with 35% of patients developing complications and 30% requiring reoperation. Risk factors including elevated body mass index, diabetes, tobacco use, steroid use, low prealbumin level, therapeutic anticoagulation, infection, history of spine surgery, multilevel spinal reconstruction, and spinal hardware were associated with complications, reoperations, and prolonged length of stay. CONCLUSIONS: Local muscle flap coverage is an effective strategy for the reconstruction of spinal defects in medically complex patients. To reduce the inherently high risks associated with paraspinous reconstruction in this challenging population, special consideration should be given to preoperative and operative variables associated with poor outcomes. Early coordination between spine and plastic surgeons should be considered in patients at high-risk of wound complications.

Primary Closure of Wide Fasciotomy and Surgical Wounds Using Rubber Band-Assisted External Tissue Expansion: A Simple, Safe, and Cost-effective Technique.

BACKGROUND: Although decompressive fasciotomy is a limb-saving procedure in the setting of acute compartment syndrome, it leaves a large wound defect with tissue edema and skin retraction that can preclude primary closure. Numerous techniques have been described to address the challenge of closing fasciotomy wounds. This study reports our experience with fasciotomy closure using rubber bands (RBs) for external tissue expansion. METHODS: Patients were informed about RB closure and split-thickness skin graft options. Only patients who opted for RB closure and had wounds that could not be approximated using the pinch test underwent the procedure. Starting from the apex and progressively advancing, the RBs were applied to the skin edges at 3 to 4 mm intervals using staples. The RBs were advanced by twisting back-and-forth to create a criss-cross pattern. One week after application, fasciotomy wounds were closed primarily or underwent further RB application, based on clinical assessment of adequacy of skin advancement, compartment tension, and perfusion. Review of a prospectively maintained database was performed, including demographics, comorbidities, etiology, wound and operative details, hospital stay, and complications. RESULTS: Seventeen consecutive patients with 25 wounds (22 fasciotomy and 3 other surgical wounds) were treated using the RB technique. Average wound length and width measured 15.7 cm (range, 5-32 cm) and 5.2 cm (range, 1-12 cm), respectively. Locations of wounds included forearm (n = 12, 48.0%), leg (n = 7, 28.0%), hand (n = 4, 16.0%), elbow (n = 1, 4.0%), and hip (n = 1, 4.0%). Eighteen of 25 wounds (72.0%) were closed primarily after 1 RB application. Additional RB application was required for 5 wounds to achieve primary closure. Between stages, patients were discharged home if they did not have other conditions requiring in-hospital stay. No complications were observed, and no revision surgeries were required. Patient satisfaction was 100%, and all indicated that they would choose the RB technique over skin grafting. CONCLUSIONS: The modified RB technique is a simple, safe, and cost-effective alternative for treating fasciotomy and other surgical defects resulting in high patient satisfaction and good cosmetic outcome, without the need for split-thickness skin graft or flap coverage.

Components Separation for Abdominal Wall Reconstruction in the Recalcitrant, High-Comorbidity Patient: A Review of 311 Single-Surgeon Cases.

PURPOSE: Components separation of the abdominal musculature remains a mainstay for closure of complicated midline and paramedian abdominal wall defects. The authors critically analyzed their experience with this technique to identify prognosticators affecting long-term clinical outcomes. METHODS: A retrospective review was performed of patients undergoing components separation by a single senior surgeon (J.M.R.) between 2000 and 2010. Numerous perioperative patient characteristics were collected and analyzed to determine their effects on long-term clinical outcomes. Multivariable logistic regression was used to predict hernia recurrence and other adverse clinical outcomes. RESULTS: A total of 311 patients were identified (male, 51.1%). Mean age was 53.1 ± 14.0 years, preoperative body mass index was 33.1 ± 8.2 kg/m, and defect width was 11.4 ± 7.5 cm. Patients who had prior hernia repair were 97.4%, with 38.3% having prior mesh placement. Average follow-up was 2.9 ± 2.4 years. Overall hernia recurrence rate was 18.3%. Postoperative complications included seroma (9.3%), superficial wound infection (9.0%), skin dehiscence (4.82%), hematoma (3.2%), deep vein thrombos or pulmonary emolbus (3.2%), and skin flap ischemia (1.0%). Respiratory comorbidity (odds ratio, [OR], 2.02; P < 0.029), prior failed mesh repair (OR, 1.86; P < 0.045), and occurrence of any postoperative complication (OR, 2.02; P < 0.034) significantly increased the risk of eventual hernia recurrence. Preoperative body mass index was not associated with hernia recurrence (P < 0.351) or increased incidence of any aforementioned postoperative complications. CONCLUSIONS: This study provides a comprehensive review of one of the largest single-surgeon experiences using components separation to date. Patients with respiratory comorbidities, prior failed mesh repair, and the occurrence of any postoperative complication are at significantly increased risk for hernia recurrence.

Patient self-report of disability of the upper extremity following osteocutaneous radial forearm free flap harvest.

BACKGROUND: The authors critically analyzed long-term upper extremity outcome after harvest of an osteocutaneous radial forearm free flap by correlating any restrictions in range of motion and strength with patient self-report of disability. METHODS: Twelve patients who had at least 1 year since surgery were evaluated with a functional examination and with the Disability of the Arm, Shoulder, and Hand questionnaire. Functional capacity was quantified by comparing range of motion of the thumbs, digits, and wrists along with pronation and supination of bilateral forearms. Pinch and grip strength measurements were obtained. RESULTS: Range of motion in full active wrist extension, wrist flexion, forearm supination, and thumb interphalangeal flexion averaged 83 percent (p = 0.01), 82 percent (p = 0.01), 83 percent (p = 0.03), and 88 percent (p = 0.03), respectively, that of the nonflap arm. Three patients demonstrated thumb opposition limited to the ring finger. Increasing scores on the questionnaire (mean, 16.6; range, 0 to 69), indicating a worsening disability, were correlated with decreasing wrist flexion (p < 0.01; Spearman correlation coefficient, 0.77) and decreasing wrist extension (p = 0.09; Spearman correlation coefficient, 0.51) of the flap arm. Radiographs revealed one malunion secondary to a postoperative pathologic fracture in the patient with the worst questionnaire score. Three patients (25 percent) stated explicitly that harvest of the osteocutaneous radial forearm free flap had created a disability. CONCLUSIONS: Objective reductions in wrist, forearm, and/or thumb range of motion are frequent after harvest of an osteocutaneous radial forearm free flap. Wrist range of motion has the greatest impact on patient self-report of disability and may in a minority of patients be perceived as causing a clinically significant disability.
