Minimally Invasive Lateral Retropleural and Retroperitoneal Approaches in Patients with Thoracic and Lumbar Osteomyelitis: Description of the Techniques and a Series of 14 Patients

The growing interest in minimally invasive approaches to the thoracic and lumbar spine is mostly secondary to the high surgical morbidity and complication rates associated with conventional open approaches. The objective was to report the largest series of patients with thoracic and lumbar vertebral osteomyelitis who underwent multilevel corpectomies using the minimally invasive lateral (MIL) retropleural and retroperitoneal approaches. The surgical techniques of the MIL approaches are illustrated and described in detail. The MIL retropleural approach was performed in 9 patients, MIL retroperitoneal approach in 3 patients, and combined MIL retropleural/retroperitoneal approach in 2 patients with thoracic, lumbar and thoracolumbar vertebral osteomyelitis, respectively. Multilevel corpectomies were successfully accomplished in all 14 patients using the MIL approaches (11 patients with 2-level corpectomy, 2 patients with 3-level corpectomy, and 1 patient with extension of a 3-level corpectomy to 6 levels). Correction of kyphotic deformity was achieved postoperatively in all 14 patients and remained stable with no proximal junctional kyphosis for a median of 10 months of follow-up on 10 patients; 4patients were lost to follow-up after discharge from the hospital. Posterior instrumentation was performed in 12patients to further support the spinal alignment. The MIL retropleural and retroperitoneal approaches described in this manuscript are feasible and safe in achieving multilevel corpectomies, anterior column reconstruction, and spinal deformity correction in patients with thoracic, lumbar, and thoracolumbar vertebral osteomyelitis.

Does an intrathecal baclofen pump impact scoliosis progression and complicate posterior spine fusion in patients with cerebral palsy?

Retrospective comparative study. In patients with cerebral palsy (CP), we determine the impact of intrathecal baclofen pumps (ITBPs) on scoliosis curve progression before posterior spine fusion (PSF) and its effects on surgical outcome. Children with CP can have rapid scoliosis progression, and high rates of surgical complications can be encountered. It is unknown whether the presence of pre-existing ITBP results in more difficult surgery and higher complication rates in similarly affected children. This is a single-center retrospective study of CP patients undergoing PSF over a 15-year period. Demographics, comorbidities, curve magnitudes, and surgical methods were compared between patients with ITBP and those without. Postoperative complications, length of intensive care unit/hospital stay, drain use and output volume, and need for further surgery were also compared. Curve progression analysis after ITBP placement was performed on a subgroup of patients with high-quality consistent radiographs. Nineteen patients with ITBP and 49 patients without ITBP met inclusion criteria. Age, comorbidities, number of levels fused, and fixation techniques during PSF were not significantly different between cohorts. ITBP patients were more likely to have PSF with osteotomy (p = 0.022). Increased intraoperative neurosurgical consultations were found for patients with ITBP (42.1% vs. 4.0%; p < 0.001). Median surgical time was 1.2h greater in patients with ITBP (6.7 vs. 5.5h, p = 0.039). There was no difference in hospital course and complications in patients with ITBP and those without ITBP. Thirty-one patients without ITB were compared with 15 ITBP patients for curve progression before PSF, demonstrating a mean rate of scoliosis progression of 9.6° ± 6.7°/year and 14.8° ± 9.1°/year (p = 0.0346), respectively. The presence of an ITBP appears to be associated with the increase in scoliosis progression; and these patients will likely have a more challenging spine fusion. Fortunately, the final outcome is not affected by ITBP. Level III.

A CASE OF OCCIPITAL MENINGOENCEPHALOCYSTOCELE IN A FULLTERM NEONATE

Background:The neural tube defect is one of the congenital anomalies which is frequently found in developing countries. A large occipital meningoencephalocystocele possess difficulties in surgical intervention, because the sac usually contains large amounts of cerebrospinal fluid, meninges, brain tissue, and, a higher rate of surgical complications, as well as a difficult positioning at intubation to minimalize the complications. Case Presentation:To report a case of neonate with a large occipital meningoencephalocystocele, which was managed with surgery by removing the extra cranial tissue containing the necrotic brain tissue and the meninges. The patient was discharge with normal wound healing, but ventriculoperitoneal shunt was not performed. Feeding difficulties and poor growth were observed several months after surgery with obvious neurological problems.Conclusions:A through management of meningoencephalocystocele involves many aspects include treatment after surgery was performed.

Intraoperative and postanesthesia care unit fluid administration as risk factors for postoperative complications in patients with head and neck cancer undergoing free tissue transfer.

This study aims to evaluate the impact of perioperative fluid administration, defined as fluid delivered intraoperatively and in the postanesthesia care unit, on postoperative outcomes. Medical records of 102 patients with oral cavity squamous cell carcinoma undergoing free flap reconstruction between January 2011 and December 2015 were reviewed. The primary endpoint was development of a postoperative complication according to the Clavien-Dindo classification. Perioperative factors recorded were Washington University Head and Neck Comorbidity Index, operating time, vasopressor use, blood loss, intraoperative fluid, and perioperative fluid. Greater perioperative fluid administration was independently associated with surgical complications, flap complications, overall incidence of any complication, and increased length of stay. Greater intraoperative fluid administration was independently associated with higher rates of surgical complications. Intraoperative delivery of vasopressors was not associated with flap or surgical complications. Receiving less perioperative fluid was associated with fewer complications and decreased length of stay.

"Found Down" Compartment Syndrome: Experience from the Front Lines of the Opioid Epidemic.

With the worsening of the opioid epidemic, there has been an increasing number of cases in which patients are "found down" following a drug overdose and develop a crush injury resulting in muscle necrosis, rhabdomyolysis, and elevated compartment pressures in a unique presentation of compartment syndrome. The purpose of the present study is to summarize our experience at a trauma center in a region with a high endemic rate of opiate abuse to provide guidance for the management of patients with "found down" compartment syndrome. We performed a retrospective review of the records of patients who had been found unconscious as the result of overdose, with findings that were concerning for compartment syndrome, and had been managed with fasciotomy or observation at the discretion of the surgeon. The patients were divided into 3 groups based on presentation (partial deficits, complete deficits, or unexaminable), and the operative findings, hospital course, laboratory values, and functional status were compared between the groups. Over 12 years, we identified 30 "found down" patients who had an examination that was concerning for compartment syndrome. Twenty-five patients were managed with fasciotomy; this group required an average of 4.2 operations and had a 20% infection rate and a 12% amputation rate. Lactate, creatine phosphokinase, and creatinine levels typically were elevated but did not correspond with muscle viability or return of function. At the time of initial debridement, 56% of patients had muscle that appeared nonviable, although muscle function returned in 28% of the patients who had questionable viability. Four patients had no motor or neurological function on initial examination, and none had meaningful return of function at the time of the latest follow-up. Of the 10 patients who had partial neurological deficits at the time of presentation and underwent fasciotomy, over half (70%) had some improvement in ultimate function. Patients who are "found down" following an opiate overdose with crush injuries resulting in compartment syndrome have a high surgical complication rate and poor recovery of function. The limited data from the present study suggest that those with absent function at the time of presentation are unlikely to gain function after fasciotomy, and the risk-benefit ratio of fasciotomy in this patient population may be different from that for patients with traumatic compartment syndrome.

The Role of Potentially Modifiable Factors in a Standard Work Protocol to Decrease Complications in Adult Spinal Deformity Surgery: A Systematic Review, Part 1

Study DesignStructured Literature Review. ObjectivesWe sought to evaluate the peer-reviewed literature for potentially modifiable patient and surgical factors that could be incorporated into a Standard Work protocol to decrease complications in adult spinal deformity (ASD) surgery. Summary of Background DataLean Methodology uses Standard Work to improve efficiency and decrease waste and error. ASD is known to have a high surgical complication rate. Several patient and surgical potentially modifiable factors have been suggested to affect complications, including preoperative hemoglobin, bone density, body mass index (BMI), age-appropriate realignment, preoperative albumin/prealbumin, and smoking status. We sought to evaluate the literature for evidence supporting these factors to include in a Standard Work protocol to decrease complications. MethodsEach of these six factors was developed into an appropriate clinical question that included the patient population, surgical intervention, a comparison group, and outcomes measure (PICO question). A comprehensive literature search was then performed. The authors reviewed abstracts and analyzed data from included studies. From 456 initial citations with abstract, 173 articles underwent full-text review. The best available evidence for clinical questions regarding the influence of these factors was provided by 93 included studies. ResultsWe found fair evidence supporting a low preoperative hemoglobin level associated with increased transfusion rates and decreased BMD and increased BMI associated with increased complication rates. Fair evidence supported low albumin/prealbumin associated with increased complications. There was fair evidence associating smoking exposure to increased reoperations, but conflicting evidence associating it with increased complications. There was no evidence in the literature evaluating age-appropriate realignment and complications. ConclusionPreoperative hemoglobin, bone density, body mass index, preoperative albumin/prealbumin, and smoking status all are potentially modifiable risk factors that are associated with increased complications in the adult spine surgery population. Developing a Standard Work Protocol for patient evaluation and optimization should include these factors. Level of EvidenceLevel II.

Impact of Renal Function on the Surgical Outcomes of Displaced Femoral Neck Fracture in Elderly Patients.

Background: The aim of this study was to investigate the relationship between estimated glomerular filtration rate (eGFR) and outcomes of bipolar hemiarthroplasty for femoral neck fracture in elderly patients, and to compare postoperative complications and mortality among groups according to eGFR. Methods: A total of 181 patients who underwent bipolar hemiarthroplasty for displaced femoral neck fracture were divided into three groups according to eGFR. Data were retrospectively analyzed. Group 1 had 96 patients with eGFR greater than or equal to 60 mL/min/1.73 m2; Group 2 had 54 patients with eGFR greater than or equal to 30 mL/min/1.73 m2 and lower than 60 mL/min/1.73 m2; and Group 3 had 31 patients with eGFR lower than 30 mL/min/1.73 m2. Postoperative complications and mortality were compared between groups at a minimum 2-year follow-up. Results: Patients in Group 3 had the longest hospital stay of the three groups (p = 0.001). The rates of medical complications did not differ significantly among groups. However, Group 2 and 3 had higher rates of surgical complications (p = 0.001) and mortality (p = 0.043) than Group 1. Severe renal impairment was associated with increased risk of postoperative complications compared to mild renal impairment (odds ratio (95% confidence interval) = 4.33 (1.32–13.19), p = 0.015). Conclusion: Patients with moderate or severe decreased eGFR associated with chronic kidney disease (CKD) could have higher postoperative complications and mortality after bipolar hemiarthroplasty compared to patients with CKD stage 1 or 2.

Halo Gravity Traction Can Mitigate Preoperative Risk Factors and Early Surgical Complications in Complex Spine Deformity.

Retrospective review of prospective cohort. We sought to examine the role of halo gravity traction (HGT) in reducing preoperative surgical risk. The impact of HGT on procedure choice, preoperative risk factors, and surgical complications has not been previously described. Patients treated with HGT before primary surgery were included. The FOCOS Score (FS) was used to quantify operative risk. FS was calculated using patient-factors (ASIA, body mass index, etiology), procedure-factors (PcF; osteotomy planned, number of levels fused, etc.), and curve magnitude (CM). Scores ranged from 0 to 100 with higher scores indicating increased risk. FS was calculated before and after HGT to see how changes in FS affected complication rates. A total of 96 patients were included. Halo-related complications occurred in 34% of patients but revision was required in only 8.3%. Average FS improved by 18 points after HGT. CM, PcF, and patient-factors all improved (P < 0.05). The greatest changes were in CM and PcF. The planned rate of three-column osteotomies dropped from 91% to 38% after HGT. FS (area under the curve [AUC]: 0.68, P = 0.023) and change in FS (AUC: 0.781, P < 0.001) was successfully able to predict the rate of surgical complications. A preoperative FS of 74 was identified as a cut-off for a higher rate of surgical complications (sensitivity 58.8%, specificity 74.7%). Patients with a reduction in FS < = 10pts were five times more likely to have a complication (relative risk 5.2, 95% confidence interval: 1.9-14.6, P < 0.001). A multivariate regression showed that change in FS was an independent predictor of complication rates (P < 0.05). FS can successfully predict surgical risk in pediatric patients with complex spinal deformity. Preoperative HGT can reduce FS and surgical risk by improving CM, lowering three-column osteotomies use, and improving body mass index. A reduction in FS after HGT predicts a lower rate of surgical complications. 3.

009 There’s More to Surgery than a Steady Hand: Patient Reported Outcomes in Gender Affirming Surgery

Many transgender individuals find that gender-affirming surgery is integral to feeling comfortable with their body. However, gender-affirming surgeries can be difficult to access, expensive, and fraught with high surgical complication rates. Moreover, surgeons may not be aware of the full nature and range of complications that occur as many patients travel for surgery and subsequently seek care for their complications in their hometown. To examine transgender patients’ self-report of complications and identify non-surgical factors (e.g. travel time to surgical appointments, thoroughness of consent process, comfort with surgeon and team, quality of discharge instructions, social supports) that are associated with increased self-reporting of complications. A retrospective survey of experiences with gender-affirming surgery was conducted in partnership with the provincial trans health program. A questionnaire with strong face validity was developed, with input from a peer reference group, and administered online after obtaining institutional research ethics approval. Instructions detailing the study and access to the survey were publicized through advertisements, social media, community organizations, and at public events within the transgender community. Data were collected from July 1st 2016 to June 30th, 2017. Participants were 18 years of age or older, and to be included in this analysis, had undergone gender-affirming surgery within the past 5 years. Participants provided data on their experience with accessing surgery, pre-operative appointments, and post-operative recovery. Participants were asked to describe any post-operative complications experienced either before or after discharge from hospital. Complications were then assigned a grade based on the Clavien-Dindo classification system and divided into grades 0-1 and ≥2. Data was then analyzed both for overall reporting of complications, and split by pre- and post-discharge, and by grade.

Low-phase angle in body composition measurements correlates with prolonged hospital stay in head and neck cancer patients

Background: Bioelectrical impedance analysis (BIA) is a method for estimating body composition. Clinically the most important parameter is the phase angle (PA), which decreases with progressing malnutrition and is highly predictive for impaired survival and mortality.Aim: To evaluate the association of low PA with the complication rate and length of hospital stay.Material and methods: A cohort of 61 head and neck cancer (HNC) patients underwent BIA prior to surgical treatment. Information on patient and tumour characteristics, treatment, and surgical complications were gathered from hospital records and correlated with BIA results.Results: The median PA was 4.5 (range, 2.7–6.5), and, in 67% of the patients, it was lower than reference values. Low PA was associated with longer hospital stay (p = .002) in the whole cohort and in the patient group with radical neck dissections it correlated with a higher surgical complication rate (p = .014), but not with Clavien–Dindo scoring for surgical complications.Conclusions and significance: BIA is a feasible instrument for analysing body composition that reflects nutritional status in cancer patients. Our results show that HNC patients have a low PA at diagnosis. Low PA is associated with a long hospital stay and an increase in the complication rate. BIA can be of clinical value in preoperative risk evaluation.

Single screw type of lag screw results higher reoperation rate in the osteosynthesis of basicervical hip fracture

BackgroundBasicervical hip fractures are relatively rare with greater biomechanical instability compared to the other types of hip fractures. Several studies have reported ambivalent surgical outcomes of basicervical hip fractures. The purpose of this multicenter study was to analyze surgical outcomes of basicervical hip fractures according to the fixation type of proximal femur and lag screw type. MethodsAmong 3220 hip fractures, 145 were classified as basicervical hip fractures. Of those, 106 patients treated with osteosynthesis were included to analyze the surgical complications according to fixation type of proximal femur: sliding hip screw(SHS) and cephalomedullary nail (CMN) groups. Surgical complications including the excessive displacement of fracture and the occurrence of reoperation were evaluated at the final follow up. We further evaluated surgical complications according to lag screw type with subgroup analysis in CMN group: single screw type, blade type and two integrated screw type. ResultsTen patients (9.4%) sustained surgical complications (5 excessive displacements and 5 reoperations). For fixation type of proximal femur, SHS group showed higher tendency of excessive displacement despite no statistical difference between the two groups (p = 0.060). For lag screw type with subgroup analysis in CMN group, single screw type showed statistically high rates of reoperation compared to the other types of lag screw (p = 0.022). ConclusionBasicervical hip fractures treated with osteosynthesis resulted to high rates of surgical complications in this study. However, they could be drastically reduced if CMN with blade type or two integrated screw type were used in the osteosynthesis of basicervical hip fractures.

Outcomes of Surgical Correction of Atlantoaxial Instability in Patients with Down Syndrome: Systematic Review and Meta-Analysis

Atlantoaxial instability (AAI) is a common cause of neurologic dysfunction and pain in patients with Down syndrome (DS), frequently requiring instrumented fusion of the upper cervical spine. Despite this, optimal treatment strategy is controversial. A systematic review of the literature was performed according to the Preferred Reporting Items for Systemic Reviews and Meta-Analysis statement to identify patients with AAI and DS were treated with upper cervical spine fusion. Patient demographics, preoperative symptoms, fixation type, and outcome measures including complications, neurologic outcomes, and bony fusion status were gathered for patients in the included publications. Meta-analysis was performed to compare outcomes of different types of fixation constructs. Of the 1191 publications retrieved, 51 met inclusion criteria, yielding 137 patients. Six fixation strategies were identified: noninstrumented (n= 6), wiring (n= 77), wiring with rods (n= 14), screw fixation (n= 33), hook and rod fixation (n= 2), and screw and wire fixation (n= 5). Constructs with screws and rods had greater bony union (P= 0.003) and a lower rate of revision surgery (P= 0.047), loss of reduction or pseudoarthrosis (P= 0.009), halo utilization (P < 0.001), and early neurologic decline (P= 0.004) compared with wiring alone. Constructs with wires and rods had greater bony union (P= 0.036) than wiring alone. Numerous fixation strategies exist for AAI in patients with DS. Using a combination of screws, rods, and wiring in appropriately selected patients may help reduce the high rate of surgical complications in these patients.

Smoking is associated with increased complications and readmission following extensor mechanism repair.

Extensor mechanism injuries are disabling injuries that require prompt evaluation and treatment and complications are often devastating. While smoking has been shown to increase complications following total joint arthroplasty, this relationship has not yet been established in those undergoing extensor mechanism repair. The purpose of this study was to evaluate the risk of smoking on postoperative complications following extensor mechanism repair. The National Surgical Quality Improvement Program (NSQIP) database was used to identify patients who underwent an extensor mechanism repair from 2005 to 2016. Patients were stratified by tobacco use, as either "current" or "nonsmokers." A multivariate logistic regression was used to control for demographic and comorbid factors while assessing perioperative complications. 5208 patients were identified, and of these, 843 (16.2%) were current smokers. Smokers were younger, male, and with lower BMIs compared to nonsmokers (p = 0.001, p = 0.003, p = 0.002, respectively). They had a higher rate of surgical complications (OR 1.61, CI 1.02-2.52), including deep surgical site infections (OR 3.27, CI 1.03-10.43) and unplanned return to the operating room (OR 2.001, 1.24-3.23). Smokers were more likely to be readmitted within 30days of surgery (OR 1.78, OR 1.09-2.90). Tobacco use is associated with a 1-2% increase in surgical, but not medical, complications following repair of extensor mechanism injuries. Smokers are at higher risk for deep infections, unplanned return to the OR, and hospital readmission. Identifying these patients preoperatively will allow surgeons to accurately counsel patients on perioperative risks. Counseling in preoperative smoking cessation is valuable for optimizing patient outcomes following extensor mechanism repair. Retrospective comparative study, Level III.

Comparison of 90-Day Complication Rates and Cost Between Single and Multiple Joint Procedures for End-Stage Arthropathy in Patients with Hemophilia.

Background:Multiple joint procedures during a single anesthetic episode have been proposed for patients with hemophilia as a way to reduce cost. The postoperative 90-day complication rate and the cost distribution between multiple joint procedures and single joint procedures for patients with hemophilia have not been well studied.Methods:Between January 1996 and December 2016, 124 patients underwent 177 surgical procedures (total knee arthroplasty, total hip arthroplasty, and ankle arthrodesis) for the treatment of hemophilic end-stage arthropathy. Forty-eight patients (39%) underwent multiple joint procedures during 1 hospitalization, and 76 patients (61%) underwent single joint procedures. The medical records were retrospectively reviewed. The patients were evaluated for complications within 90 days postoperatively and the cost during hospitalization. Risk factors related to complications were further analyzed.Results:Twenty-seven of the 124 patients experienced 29 complications within 90 days postoperatively, representing a complication rate of 16.4% for all procedures. The patients who had undergone multiple joint procedures had a higher rate of surgical complications than those who had undergone a single joint procedure (14.6% vs. 3.9%; p = 0.039). The patients who had had multiple joint procedures had similar rates of hematological complications (8.3% vs. 9.2%; p = 0.867) and total complications (31.3% vs. 18.4%; p = 0.100) compared with those who had had a single joint procedure. There was no difference between the patients who had had multiple joint procedures and those who had had a single joint procedure with regard to the cost of the coagulation factor (p = 0.212).Conclusions:The performance of multiple joint procedures during a single anesthetic episode is a safe approach for patients with hemophilia with end-stage arthropathy, with no substantial increase in the 90-day complication rate in comparison with that following a single joint procedure. The performance of multiple joint procedures under a single anesthetic episode can save cost and is more cost-effective when managing patients with hemophilia who have end-stage arthropathy.Level of Evidence:Therapeutic Level III.

Robotic pancreas transplantation: the state of the art.

Robotic pancreas transplantation is a novel procedure that aims to reduce surgical invasiveness, and thereby limit complications related to the surgical access. Given that few centers are providing robotic transplantation, this review serves as a state of the science article to outline early experiences and highlight areas for future research. Pancreas transplantation results in relatively high rates of wound and other surgical complications that are known to deleteriously impact outcomes. The minimally invasive, robotic-assisted approach decreases wound complications. Because of the obesity epidemic, overweight and obese status is encountered in an increasing number of transplant candidates. These candidates are subject to increased wound-related complications and most benefit from a robotic approach. The first clinical reports on laparoscopic, robotic-assisted kidney and pancreas transplantation indicate a significant decrease in wound complications and excellent outcomes in obese patients otherwise denied access to transplantation. With excellent results achieved in surgically challenging patients and further accumulation of experience, laparoscopic, robotic-assisted pancreas and kidney transplantation may evolve to a new standard approach.

Surgical decision-making in the management of childhood tumors of the CNS disseminated at presentation.

OBJECTIVE It is relatively unusual for pediatric CNS tumors to be disseminated at presentation, and the literature on the clinical features, management, and outcomes of this specific group is scarce. Surgical management in this population is often challenging, particularly in the presence of hydrocephalus. The authors present their recent experience of treating pediatric CNS tumors that were disseminated at presentation, and they compare these lesions with focal tumors. METHODS The authors performed a retrospective review of prospectively collected data on children presenting to a tertiary center between 2003 and 2016 inclusive. RESULTS Of 361 children with CNS tumors, the authors identified 53 patients with disease dissemination at presentation (male/female ratio 34:19, median age 3.8 years, age range 7 days to 15.6 years) and 308 without dissemination at presentation (male/female ratio 161:147, median age 5.8 years, age range 1 day to 16.9 years). Five tumor groups were studied: medulloblastoma (disseminated n = 29, focal n = 74), other primitive neuroectodermal tumor (n = 8, n = 17), atypical teratoid rhabdoid tumor (n = 8, n = 22), pilocytic astrocytoma (n = 6, n = 138), and ependymoma (n = 2, n = 57). The median follow-up duration in survivors was not significantly different between those with disease dissemination at presentation (64.0 months, range 5.2-152.0 months) and those without it (74.5 months, range 4.7-170.1 months) (p > 0.05). When combining data from all 5 tumor groups, dissemination status at presentation was significantly associated with a higher risk of requiring CSF diversion, a higher surgical complication rate, and a reduced likelihood of achieving gross-total resection of the targeted lesion (all variables p < 0.05). Differences between the 5 tumor groups were evident. No factors that predicted the need for permanent CSF diversion following temporary external ventricular drainage were identified on multivariate analysis, and there was no clear superiority of either ventriculoperitoneal shunt surgery or endoscopic third ventriculostomy as a permanent CSF diversion procedure. CONCLUSIONS Tumor type and dissemination status at initial presentation significantly affect outcomes across a range of measures. The management of hydrocephalus in patients with CNS tumors is challenging, and further prospective studies are required to identify the optimal CSF diversion strategy in this population.

Trends in the Surgical Management of Acromioclavicular Joint Arthritis Among Board-Eligible US Orthopaedic Surgeons

(1) Define the epidemiologic trend of distal clavicle excision (DCE) for acromioclavicular (AC) joint arthritis among board-eligible orthopaedic surgeons in the United States, (2) describe the rates and types of reported complications of open and arthroscopic DCE, and (3) evaluate the effect of fellowship training on preferred technique and reported complication rates. The American Board of Orthopaedic Surgery (ABOS) database was used to identify DCE cases submitted by ABOS Part II Board Certification examination candidates. Inclusion criteria were predetermined using a combination of ICD-9 and CPT codes. Cases were dichotomized into 2 groups: open or arthroscopic DCE. The 2 groups were then analyzed to determine trends in annual incidence, complication rates, and surgeon fellowship training. From April 2004 to September 2013, there were 3,229 open and 12,782 arthroscopic DCE procedures performed and submitted by ABOS Part II Board Eligible candidates. Overall, the annual incidence of open DCE decreased (78-37 cases per 10,000 submitted cases, P= .023). Although the annual number of arthroscopic DCE remained steady (1160-1125, P= .622), the percentage of DCE cases performed arthroscopically increased (65%-79%, P= .033). Surgeons without fellowship training were most likely to perform a DCE via an open approach (31%) whereas surgeons with sports medicine training were more likely to perform DCE arthroscopically compared with other fellowship groups (88%, P<.001). Open DCE was associated with a higher surgical complication rate overall when compared with arthroscopic DCE (9.4% vs 7.6%, respectively; P < .001). When compared with other fellowship-trained surgeons, sports medicine surgeons maintained a lower reported surgical complication rate whether performing open or arthroscopic DCE (5.5%, P= .027). In recent years, open management of AC joint arthritis has declined among newly trained, board-eligible orthopaedic surgeons, possibly because of an increased complication rate associated with open treatment. Fellowship training was significantly associated with the type of treatment (open vs arthroscopic) rendered and complication rates. Level IV, case series.

Preliminary report: Surgical outcomes following genitoplasty in children with moderate to severe genital atypia

Prior studies of outcomes following genitoplasty have reported high rates of surgical complications among children with atypical genitalia. Few studies have prospectively assessed outcomes after contemporary surgical approaches. The current study reported the occurrence of early postoperative complications and of cosmetic outcomes (as rated by surgeons and parents) at 12 months following contemporary genitoplasty procedures in children born with atypical genitalia. This 11-site, prospective study included children aged ≤2 years, with Prader 3-5 or Quigley 3-6 external genitalia, with no prior genitoplasty and non-urogenital malformations at the time of enrollment. Genital appearance was rated on a 4-point Likert scale. Paired t-tests evaluated differences in cosmesis ratings. Out of 27 children, 10 were 46,XY patients with the following diagnoses: gonadal dysgenesis, PAIS or testosterone biosynthetic defect, severe hypospadias and microphallus, who were reared male. Sixteen 46,XX congenital adrenal hyperplasia patients were reared female and one child with sex chromosome mosaicism was reared male. Eleven children had masculinizing genitoplasty for penoscrotal or perineal hypospadias (one-stage, three; two-stage, eight). Among one-stage surgeries, one child had meatal stenosis (minor) and one developed both urinary retention (minor) and urethrocutaneous fistula (major) (Summary Figure). Among two-stage surgeries, three children developed a major complication: penoscrotal fistula, glans dehiscence or urethral dehiscence. Among 16 children who had feminizing genitoplasty, vaginoplasty was performed in all, clitoroplasty in nine, external genitoplasty in 13, urethroplasty in four, perineoplasty in five, and total urogenital sinus mobilization in two. Two children had minor complications: one had a UTI, and one had both a mucosal skin tag and vaginal mucosal polyp. Two additional children developed a major complication: vaginal stenosis. Cosmesis scores revealed sustained improvements from 6 months post-genitoplasty, as previously reported, with all scores reported as good or satisfied. In these preliminary data from a multi-site, observational study, parents and surgeons were equally satisfied with the cosmetic outcomes 12 months after genitoplasty. A small number of patients had major complications in both feminizing and masculinizing surgeries; two-stage hypospadias repair had the most major complications. Long-term follow-up of patients at post-puberty will provide a better assessment of outcomes in this population. In this cohort of children with moderate to severe atypical genitalia, preliminary data on both surgical and cosmetic outcomes were presented. Findings from this study, and from following these children in long-term studies, will help guide practitioners in their discussions with families about surgical management.

Bicondylar Tibial Plateau Fractures: A Critical Analysis Review.

* Bicondylar tibial plateau fractures represent a broad category of complex, high-energy injuries associated with a high surgical complication rate.* Computed tomography and magnetic resonance imaging aid in diagnosis, classification, and surgical planning and should be considered during the initial evaluation or after provisional stabilization is performed as part of staged treatment.* No one classification system has superior descriptive traits or reliability. Simply classifying the fracture as unicondylar (partial articular) or bicondylar (complete articular) is the most reliable approach.* Malalignment, especially in the coronal plane, and instability predict poor outcomes and should direct surgical intervention. Articular displacement is less predictive.* Dual plating is the most stable type of fixation biomechanically but is associated with soft-tissue complications.* Single lateral locked plating is an alternative fixation type for bicondylar fractures without a large posteromedial coronal fracture line.* Hybrid external fixators are another means of fixation that avoid large exposures and associated soft-tissue disruption.* No one fixation strategy is superior in all cases. Patient and injury characteristics should be evaluated on a case-by-case basis to optimally direct the treatment of these complex injuries.

An Exceedingly Rare Combination of Truncus Arteriosus and Total Anomalous Pulmonary Venous Connection

A neonate with truncus arteriosus (TA) and concomitant total anomalous pulmonary venous connection (TAPVC) is presented. The diagnosis of TA was made on antenatal ultrasound. An echocardiogram performed immediately after birth confirmed TA with a regurgitant quadrileaflet truncal valve. This echo further demonstrated all four pulmonary veins connected to a supracardiac confluence draining to the superior vena cava (SVC) via a partially obstructed ascending vein. Cardiac computed tomography confirmed TA and TAPVC, and demonstrated an ascending vein arising from the supracardiac confluence, passing over the aorta before inserting into the SVC. The patient underwent prompt single-stage repair. The postoperative course was complicated by a pulmonary embolism requiring surgical intervention, and severe truncal valve regurgitation necessitating a third surgery within the first 4 months of life. Review of the literature suggests this combination of defects is exceedingly rare and, of those cases reported, there is a high surgical and postsurgical complication rate.
