Fractures in the Setting of Constriction Band Syndrome: A Case Series of Three Patients with Extremity Fractures at the Site of a Constriction Band.

Constriction band syndrome (CBS) is a rare condition where fibrous bands constrict one or more parts of the fetus with varying manifestations such as autoamputation, acrosyndactyly, and neuropathy. However, isolated extremity fractures in the setting of constriction band syndrome are even more rare, with only two reported cases in the literature. There are few guidelines on the management of CBS due to small case numbers, the variability of presentation between patients, and the lack of consensus on etiology and pathogenesis. In this small case series, we describe the presentation and management of three patients at our institution with extremity fractures at the site of severe constriction bands with neurologic injuries or vascular compromise. We also review the literature on this topic to provide further context. Intramedullary stabilization of the fracture with a k-wire allowed for soft tissue healing in two of our patients.

Characterizing Negative Online Reviews of Pediatric Orthopaedic Surgeons.

BACKGROUND: The growing focus on subjective patient experiences has created an increase in popularity for physician rating websites. The purpose of this study was to characterize extremely negative reviews of pediatric orthopaedic surgeons. METHODS: Pediatric orthopaedic surgeons were randomly selected using the Pediatric Orthopaedic Society of North America comprehensive list of surgeons. A search was then performed on Healthgrades.com, Vitals.com, and Yelp.com for 1-star reviews. Reviews were classified into clinical and nonclinical categories. Statistical analyses were performed regarding the frequency of reviews and complaints for each respective category. RESULTS: Of the 279 one-star reviews categorized, 248 reviews (88.9% of reviews) included nonclinical complaints, and 182 reviews (65.2% of reviews) included clinical complaints. Nonsurgical patients were associated with 255 reviews, and the remaining 24 were related to surgical patients. Of the 430 comments within reviews, 248 referenced nonclinical aspects of care, and 182 referenced clinical care. Clinical factors most frequently noted included clinical disagreement (37%), unclear treatment plan (25%), complication (17%), misdiagnosis (15%), uncontrolled pain (13%), and delay in care (8%). The most addressed nonclinical factors included physician bedside manner (68%), time spent with provider (21%), wait time (18%), unprofessional staff (17%), scheduling issues (9%), cost (8%), and billing (8%). Compared with surgical reviews, nonsurgical reviews were more likely to contain nonclinical complaints (rate ratio: 1.5; P<0.05) and less likely to contain clinical complaints (rate ratio: 0.7; P<0.05). The most common complaint by surgical patients was complications (91.7%). CONCLUSIONS: To our knowledge, this is the first study to examine the factors associated with negative reviews of pediatric orthopaedic surgeons. The majority of reviews of pediatric orthopaedic surgeons were left by nonsurgical patients and were related to nonclinical aspects of care. We also found surgeon-dependent factors such as poor physician bedside manner, unclear treatment plan, or parents' disagreement with treatment plan were the most common reasons for negative reviews.

Motion laboratory gait analysis and orthopedic resident education: preliminary results.

Gait analysis in the pediatric and adult orthopedic patient populations can adjunct the diagnosis and treatment of a multitude of musculoskeletal conditions. Understanding of normal and abnormal gait biomechanics is an important aspect of orthopedic residency; yet, there is great variability in the time residency programs dedicate to gait analysis education. The purpose of this study was to investigate if formal gait analysis education during residency improves an orthopedic resident's understanding of normal and pathologic gait. Five residency programs consisting of 81 resident subjects were surveyed at the beginning of the 2016-2017 academic year. The residents were divided into those with formal gait analysis education (group A) and those without (group B). Each resident was sent an online survey with 11 questions from former orthopedic in-training exams (OITE) regarding gait pattern analysis. The average number of correct questions was compared between the two groups with Student's t-test. Fifty-three of the 81 surveys sent out were completed. There were 23 subjects in group A and 30 in group B. All five programs and all postgraduate years (PGYs) were represented (PGY1: 10, PGY2: 12, PGY3: 12, PGY4: 6, PGY5 12). The average score for all residents was 5.6 out of 11 correct (51%). The residents from group A averaged a significantly higher score (6.3) than group B (5.0) (P = 0.017). Understanding gait biomechanics is a critical skill for orthopedic surgeons, and residency training often lacks sufficient training in their curriculum. A good understanding of gait analysis allows orthopedic surgeons to analyze gait disturbances and develop patient-specific treatment plans in adult and pediatric populations. This study found improved knowledge of gait patterns amongst orthopedic residents with formal education. Even though the residents with formal education fared better than their counterparts, the overall percent correct was still low (51%). Evidence: Level 3: Prospective Cohort Study.

Syndromic Scoliosis: National Trends in Surgical Management and Inpatient Hospital Outcomes: A 12-Year Analysis.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Evaluate the trends in management and inpatient outcomes in patients with syndromic scoliosis undergoing spinal deformity correction. SUMMARY OF BACKGROUND DATA: Syndromic scoliosis (SS) refers to scoliosis that is most commonly associated with systemic disease including Ehler Danhlos syndrome (EDS), Marfan syndrome (MF), Down syndrome (DS), Achondroplasia (AP), and Prader-Willi syndrome (PWS). Limited data exist evaluating hospital outcomes in patients with SS undergoing spinal deformity correction. METHODS: The Kids' Inpatient Database (KIDS) was queried from 2001 to 2012 to identify all pediatric patients with scoliosis undergoing spinal fusion. These patients were then sub-divided into two cohorts: (1) patients with idiopathic scoliosis (IS) and (2) patients with syndromic scoliosis. Trends in surgical management, and postoperative morbidity and mortality were assessed. Length of stay and total hospital charges were additionally analyzed. A sub-analysis to characterize outcomes in each syndrome was also performed. RESULTS: An estimated 1071 patients with SS were identified and compared with 24,989 pediatric patients with IS. MF (36.8%), Down syndrome (16.0%), and PWS (14.9%) were the most common diagnoses among patients with SS. Between 2001 and 2012, there was a significant decline in the number of anterior procedures performed in both cohorts. Conversely, the number of posterior based procedures increased. SS was associated with increased major complications (2.7% compared with 1.0% in IS; P < 0.001) and minor complication rates (41.0% compared with 28.5% in IS; P < 0.001). Patients with AP incurred the highest rate of major complications (10.7%), minor complications (60.8%), and intraoperative durotomies (6.1%). Total hospital charges increased significantly over the 12-year span. CONCLUSION: Trends in management of syndromic scoliosis have paralleled that of idiopathic scoliosis. Syndromic scoliosis is associated with increased risks with surgical deformity correction. Further prospective studies are warranted to evaluate the reasons for these differences.

The modified Dunn procedure for unstable slipped capital femoral epiphysis: a multicenter perspective.

BACKGROUND: The modified Dunn procedure has rapidly gained popularity as a treatment for unstable slipped capital femoral epiphysis (SCFE), but limited data exist regarding its safety and efficacy. The purpose of this study was to present results and complications following this procedure in a large multicenter series. METHODS: We reviewed the outcomes of all patients who had been treated with the modified Dunn procedure by five surgeons from separate tertiary-care institutions. All slipped capital femoral epiphyses were defined as unstable according to the Loder criteria. Patients with less than one year of follow-up and those with an underlying endocrinopathy or syndrome were excluded. All surgical procedures were performed by pediatric orthopaedic surgeons who had specific training in the modified Dunn procedure. Operative reports, outpatient records, and follow-up radiographs were used to determine the demographic information, type of fixation, final slip angle, presence of osteonecrosis, and any additional complications. Standardized surveys were administered to determine the pain level (0 to 10 scale), satisfaction (0 to 100 scale), function (modified Harris hip score, 0 to 91 scale), and activity level (UCLA [University of California Los Angeles] activity score, 0 to 10 scale) at time of the most recent follow-up. RESULTS: Twenty-seven patients (twenty-seven hips) with a mean of 22.3 months (range, twelve to forty-eight months) of follow-up met the inclusion criteria. Four patients (15%) had broken implants at three to eighteen weeks after surgery and required revision fixation. Seven patients (26%) developed osteonecrosis at a mean of 21.4 weeks (range, ten to thirty-nine weeks), with each surgeon having at least one case of osteonecrosis. The mean slip angle at the time of the most recent follow-up was 6° (95% confidence interval, 2° to 11°). Patients who did not develop osteonecrosis had significantly better clinical results compared with those who developed osteonecrosis, as demonstrated by a lower mean pain score (0.3 compared with 3.1, p = 0.002), higher level of satisfaction (97.1 compared with 65.8, p = 0.001), higher modified Harris hip score (88.0 compared with 60.0, p = 0.001), and higher UCLA activity score (9.3 compared with 5.9, p = 0.031). CONCLUSIONS: This largest reported series of unstable slipped capital femoral epiphyses treated with the modified Dunn procedure demonstrated that the procedure is capable of restoring anatomy and preserving function after a slip but that implant complications and osteonecrosis can and do occur postoperatively.

The Dega osteotomy: a versatile osteotomy in the treatment of developmental and neuromuscular hip pathology.

BACKGROUND: The purpose of this study is to evaluate the use of the Dega osteotomy in the treatment of hip pathology resulting from both developmental dysplasia (DDH) and neuromuscular disease (NM). METHODS: We retrospectively reviewed the results of one surgeon's operative experience with the Dega osteotomy for the treatment of DDH and NM. Forty-four patients (50 hips) with an average length of follow-up of 53 months were identified. The Dega was customized at the time of surgery to provide more anterior or posterior coverage depending on the needs of the individual hip. RESULTS: In all cases, there were no intraoperative complications and all hips were well reduced postoperatively. In the DDH group, there were 22 children (26 hips), who underwent surgery at a mean age of 3.1 years. Thirteen hips had a concomitant open reduction and 4 had a femoral osteotomy. There were 5 complications: 2 femoral head lateralizations, 2 avascular necroses (asymptomatic), and 1 traumatic dislocation. One patient (1 hip) had a reoperation. All patients had unlimited physical activity with no limp with an improvement in the acetabular index from 37 degrees preoperatively to 13 degrees at last follow-up. In the NM group, there were 22 children (24 hips), who underwent surgery at a mean age of 6.3 years. Twenty-three hips had concomitant procedures performed. At an average of 56 months postoperatively, all patients were pain-free. There were 5 complications: 1 graft dislodgement, 1 graft collapse, and 3 femoral head lateralizations. Three patients (3 hips) had a reoperation. Acetabular index improved from 36 degrees preoperatively to 14 degrees, and the migration percentage ranged from 84% to 14%. CONCLUSIONS: In this series of Dega osteotomies, one of the largest in the English literature, the osteotomy seems safe and effective in the treatment of both DDH and NM hip disease. The Dega osteotomy is utilitarian, as it may provide increased acetabular coverage anteriorly or posteriorly depending on where it is hinged. LEVEL OF EVIDENCE: Therapeutic study, clinical case series: level IV.

Clinical outcome in total hip arthroplasty using a cemented titanium femoral prosthesis.

Between 1988 and 1993, 118 total hip arthroplasties were carried out using cemented titanium alloy stems with modular cobalt-chrome heads. At a mean follow-up of 66.2 months, the overall clinical failure rate as a result of aseptic loosening of the femoral stem was 11.5%. Most failures occurred with smaller stems, especially in heavier patients. Clinical and radiographic data suggest that failure of femoral component fixation was due to high stresses in the cement mantle associated with the increased flexibility of the smaller stems. Radiographs of successful arthroplasties in patients with larger stems showed proximal stress shielding in most. The findings in this study do not support the contention that titanium alloys provide an advantage over more rigid materials in the manufacture of cemented femoral components for total hip arthroplasty.
