Postoperative CT imaging to characterize fusion in pediatric and adolescent vertebral column resection.

BACKGROUND: Vertebral column resection (VCR) is a powerful corrective technique for the management severe, rigid spinal deformities but does carry a relatively high complications rate. One of the feared complications is pseudarthrosis which places the patient at risk for implant failure. We present a single-center experience with post-operative computed tomography (CT) imaging at the osteotomy site to screen for impending pseudarthrosis. METHODS: A retrospective review of a single surgeon series of posterior-only VCR performed for severe pediatric and adolescent spinal deformities was performed. Demographic, radiographic, and clinical data were collected. Patients underwent postoperative CT imaging at the osteotomy site 6-9 months following VCR with grading of the osteotomy fusion. Patients with impending pseudarthrosis were recommended for prophylactic revision surgery. RESULTS: Thirty-three patients were included (mean age 11.6 ± 4.9 years, 54.5% female), undergoing a mean 1.9 level VCR. Kyphoscoliosis accounted for 75.7% (N = 25/33) of cases with 45.5% of all cases being congenital etiology and 60.6% having at least 1 previous surgery. Postoperative CT imaging was performed in 22 patients at a mean of 7.8 months following VCR. Two patients were identified as having impending pseudarthrosis with one undergoing revision surgery to enhance the posterior fusion, with addition of a third rod while one patient refusing surgery who subsequently developed broken hardware requiring revision surgery. No patient with a stable fusion on CT imaging developed a clinically significant pseudarthrosis. DISCUSSION: Postoperative CT imaging of the osteotomy is useful in screening for impending pseudarthrosis and can aide in decision making for clearance to return to activity or the need for prophylactic intervention following VCR in pediatric and adolescent patients. We advocate that obtaining routine CT imaging of the osteotomy site at 6-9 months may identify potential complications earlier and allow for prophylactic intervention.

Comparison of Short-Term Outcomes After Total Ankle Replacement and Ankle Arthrodesis: An ACS-NSQIP Database Study.

Over the past 2 decades, several studies comparing intermediate- and long-term outcomes after total ankle replacement (TAR) versus ankle arthrodesis (AA) have reported differing rates of complications and outcomes. Recently, there has been a dramatic increase in patients undergoing TARs without any epidemiologic studies examining the short-term and perioperative complications. The purpose of this prognostic study was to compare perioperative outcomes after TAR and AA using data from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database between 2012 and 2017. Patient data were collected from the NSQIP database for surgeries between January 2012 and December 2017 using Current Procedural Terminology codes 27700, 27702, 29899, and 27870. Patients were excluded if treated for fracture, infection, or revision procedures. The outcomes of interest were readmission and reoperation related to initial surgery, surgical site infections, and hospital length of stay. There were 1214 patients included-1027 (84.6%) TAR and 187 (15.4%) AA. The TAR patients were older, had a lower body mass index, and were less likely to have insulin-dependent diabetes. Readmission rate and length of stay was similar between groups. Multivariate regression revealed higher anesthesia severity scores (P = .0007), diabetes mellitus (P = .029), and AA (P = .049) had positive correlations with adverse outcomes. We report a lower complication rate with TAR than previously described. AA arthrodesis is associated with a higher risk of perioperative complications, including deep surgical site infections and reoperations. There were no differences between the 2 groups comparing superficial infection, wound dehiscence, or readmissions in the first 30 days.Levels of Evidence: Level V.

The Insidious Effects of Childhood Obesity on Orthopedic Injuries and Deformities.

The current childhood obesity epidemic, affecting approximately 20% of American children and adolescents, is accompanied by unique orthopedic manifestations. The growing musculoskeletal system is susceptible to the endocrine effects of obesity, resulting in decreased bone mass and quality. As a result, obese children are at increased risk of musculoskeletal injury, fracture, and lower extremity deformities. The efficacy of nonoperative treatment such as casting or bracing may be limited by body habitus and surgical treatment is accompanied by increased risk of perioperative complications.

Persistence and Progression of Airway Obstruction in Children With Early Onset Scoliosis.

BACKGROUND: Obstructive lung disease occurs in 30% of children with early onset scoliosis (EOS); changes in degree of airway obstruction over time have not been reported. METHODS: Longitudinal patterns of incidental, persistent, and progressive airway obstruction were retrospectively analyzed in a cohort of children with EOS with at least 1 forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) value <85% on serial spirometric assessments over a ≥3-year observation period. The prevalence of clinical features and the severity of coronal and sagittal spine deformities for each group at the beginning and end of the study period were compared. RESULTS: Airway obstruction was incidental in 12 (24%) and persistent in 37 (76%) of 49 children with EOS. Twenty of 37 (54%) of those with persistent obstruction developed progressive airway obstruction. The decline in FEV1/FVC over 6±2 years was insignificant in the incidental group (4%±2%) and the persistent nonprogressive group (7%±4%) but significant in the progressive group (13%±4%, t test; P=0.002). In total, 29% of the 49 children at the onset and 57% at the end of the study had airway obstruction. The incidental, persistent nonprogressive, and progressive groups did not differ with regard to age, diagnosis distribution, or sex. The initial coronal curve size, apex, direction of the curve, and degree of kyphosis were statistically similar among the 3 groups. Coronal curve magnitude inversely correlated with FEV1/FVC at the end but not the beginning of the study (r=-0.19, P=0.002). Six of 19 responded to bronchodilator treatment, suggesting concurrent asthma. Airway obstruction did not relate to restrictive pulmonary abnormalities measured by FVC at first or last timepoints [slope=-0.076 (95% confidence interval, -0.99 to 0.038; P=0.19)]. Changes in degrees of airway obstruction and restrictive lung disease over time did not correlate [slope=-0.125 (95% confidence interval, -0.294 to 0.044; P=0.14)]. CONCLUSIONS: Children with EOS and progressive airway obstruction represent an important subgroup which may require new surgical and nonsurgical treatment strategies to prevent loss of lung function over time.

Flexible Fixation in Foot and Ankle Surgery.

Flexible fixation has been described and utilized in various aspects of foot and ankle surgery over the past several decades. In regards to ankle surgery, flexible fixation devices have been used for stabilization of the ankle syndesmosis and augmentation of lateral collateral ankle ligament repair. In the foot, flexible fixation devices have been incorporated into hallux valgus or varus correction, Lisfranc injury repair, and more recently spring ligament repair augmentation. This article reviews the various applications for flexible fixation in foot and ankle surgery, as well as evidence-based literature on surgical applications and clinical outcomes.

Barbed sutures and wound complications in plastic surgery: an analysis of outcomes.

BACKGROUND: Barbed sutures may expedite dermal approximation and improve tissue support while requiring less time and material than conventional sutures. Several types of barbed sutures are available, each with unique advantages. OBJECTIVES: The authors sought to determine whether the incidence of complications differed after wound approximation in plastic surgery when various brands of barbed vs nonbarbed traditional sutures were employed. METHODS: The authors conducted a retrospective review of outcomes in body contouring, free flap, and breast reconstruction. Suture type and closure method were noted for each case. The number of complications after traditional 2-layer closure with nonbarbed sutures was compared with the number of complications after closure via 1- and 2-layer techniques with several brands of barbed sutures, and the brands of barbed sutures were compared with each other. RESULTS: A total of 1011 unique surgical procedures, including 298 procedures with barbed sutures and 713 procedures with nonbarbed sutures, were performed by 5 members of the plastic surgery faculty. The 2-layer technique with barbed sutures was associated with significantly higher rates of wound separation than traditional methods. Excessive erythema along the incision site was significantly more frequent with Quill barbed sutures than with V-Loc barbed sutures. CONCLUSIONS: Barbed sutures were associated with significantly higher rates of minor wound complications, specifically when the 2-layer closure technique was performed. Significantly higher rates of erythema were associated with Quill barbed sutures than with V-Loc barbed sutures. LEVEL OF EVIDENCE 4: Risk.

The impact of perioperative hypothermia on plastic surgery outcomes: a multivariate logistic regression of 1062 cases.

BACKGROUND: Perioperative hypothermia has been associated with increased rates of infection, prolonged recovery time, and coagulopathy. OBJECTIVES: The authors assessed the impact of hypothermia on patient outcomes after plastic surgery and analyzed the impact of prewarming on postoperative outcomes. METHODS: The medical charts of 1062 patients who underwent complex plastic surgery typically lasting at least 1 hour were reviewed. Hypothermia was defined as a temperature at or below 36°C. Postoperative complication data were collected for outcomes including infection, delayed wound healing, seroma, hematoma, dehiscence, deep venous thrombosis, and overall wound problems. Odds ratios (ORs) were estimated from 3 multivariate logistic regression models of hypothermia and one model of body contouring procedures that included prewarming as a parameter. RESULTS: Perioperative hypothermia was not a significant predictor of wound problems (OR = 0.83; P = .28). In the stratified regression model, hypothermia did not significantly impact wound problems. The regression model measuring the interaction between hypothermia and operating time did not show a significantly increased risk of wound problems. Prewarming did not significantly affect perioperative hypothermia (P = .510), and in the model of body contouring procedures with prewarming as a categorical variable, massive weight loss was the most significant predictor of wound complications (OR = 2.57; P = .003). Prewarming did not significantly affect outcomes (OR = 1.49; P = .212). CONCLUSIONS: Based on univariate and multivariate models in our study, mild perioperative hypothermia appears to be independent of wound complications. LEVEL OF EVIDENCE 4: Risk.

An alternative outpatient care model: postoperative guest suite-based care.

BACKGROUND: Patients recovering from outpatient surgery are responsible for managing their pain, managing ambulation, and even implementing thromboembolism prophylaxis after discharge. Because of the importance of postoperative care to prevent complications, a model of care that helps a patient transition to independent self-care could provide optimal results. OBJECTIVES: The authors investigated the safety and morbidity rate for patients who underwent body contouring procedures and overnight care at an attached, nurse-staffed guest suite facility. METHODS: A retrospective review was conducted of 246 patients who underwent major body contouring and who stayed at least 1 night in the guest suite facility. Major complications included a return to the operating room within 48 hours, major wound infection, and unplanned hospitalization within 48 hours. Minor complications included any postsurgical effect necessitating unplanned physician intervention within the first 30 days. Univariate analyses correlating patient characteristics and complication rates were conducted, as well as comparison of complication rates among same procedures reported in the literature. RESULTS: The complication rate (major and minor complications) was 25.20%. Surgical site infection occurred in 8.13% of patients. The most common wound complication was erythema around the incision site (12.20%). Death, deep vein thrombosis, or pulmonary embolism did not occur. Comparison with relevant results reported in the literature indicated a significant reduction in the occurrence of postoperative venous thromboembolism. CONCLUSIONS: Patient education after surgery is essential to healing and adequate care. The guest suite model provides improved care and education for the patient and family postsurgery by addressing some of the known risk factors of plastic surgery. LEVEL OF EVIDENCE: 4.

Effectiveness of prophylactic antibiotics in outpatient plastic surgery.

BACKGROUND: The effectiveness of prophylactic antibiotics has not been established for patients who undergo plastic surgery as outpatients, and consensus guidelines for antibiotic administration in clean-contaminated plastic surgery are not available. OBJECTIVES: In a retrospective study of outpatients, the authors examined preoperative timing of prophylactic antibiotics, whether postoperative antibiotics were administered, and whether any correlations existed between these practices and surgical complications. METHODS: The medical records of 468 plastic surgery outpatients were reviewed. Collected data included preoperative antibiotic timing, postoperative antibiotic use, comorbidities, and complications. Rates of complications were calculated and compared with other data. RESULTS: All 468 patients received antibiotics preoperatively, but only 93 (19.9%) received them ≥1 hour before the initial incision. Antibiotics were administered 15 to 44 minutes before surgery in 217 patients (46.4%). There was no significant difference in complication rates between the 315 patients who received postoperative prophylactic antibiotics (16.2%) and the 153 who did not (20.9%). Comorbidities had no bearing on postoperative complications. CONCLUSIONS: Postoperative antibiotic prophylaxis may be unnecessary for outpatient plastic surgery patients. LEVEL OF EVIDENCE: 3.
