No Delay in Age of Crawling, Standing or Walking with Pavlik Harness Treatment: A Prospective Cohort Study.

BACKGROUND: Pavlik harness treatment is the standard of care for developmental dysplasia of the hip in infants younger than 6 months. The effect of Pavlik harness treatment on the achievement of motor milestones has not previously been reported. METHODS: In this prospective cohort study, 35 patients were prospectively enrolled to participate and received questionnaires with sequential clinical visits monitoring treatment of their developmental dysplasia of the hip. One-sample Student t -tests assessed differences in milestone attainment age, and the Benjamini-Hochberg procedure was conducted to decrease the false discovery rate. Post hoc power analyses of each test were conducted. The age of achievement of eight early motor milestones were recorded and compared with a previously published cohort of healthy infants. RESULTS: Infants treated with a Pavlik harness achieved four early motor milestones markedly later than the reported age of achievement in a historical control group. These milestones included "roll supine" (5.3 vs. 4.5 months; P = 0.039), "roll prone" (5.7 vs. 5.0 months; P = 0.039), "sit" (6.4 vs. 5.2 months; P < 0.001), and "crawl on stomach" (7.7 vs. 6.6 months; P = 0.039). However, there was no difference in time to achievement of later motor milestones of "crawl on knees," "pull to stand," and "independent walking." CONCLUSION: Several early motor milestones were achieved at a statistically significantly later time than historical control subjects not treated in a Pavlik harness. Despite statistical significance, the small delays in early motor milestones were not thought to be clinically significant. No differences were observed in the later motor milestones, including knee crawling, standing, and independent walking. Clinicians and parents may be reassured by these findings. LEVEL OF EVIDENCE: Therapeutic Level II-prospective study.

Temporary Flexible Rods for Correction of Severe Pediatric Spinal Deformity.

Surgical correction of large, rigid scoliotic and kyphotic curves carries an increased risk of perioperative complications, such as neurological injury and excessive blood loss, compared with correction of less severe curves. Titanium temporary flexible rods (TFRs), designed for pediatric long bone fracture fixation, may be helpful as adjuncts to achieve gradual, stepwise intraoperative correction of severe pediatric spinal deformities. A retrospective review was conducted of spinal fusion cases for pediatric scoliosis or kyphosis at our institution that used TFRs as a correction technique from 2007 to 2019. Patients underwent posterior spinal fusion with predominantly pedicle screw instrumentation. Intraoperatively, a non-contoured titanium elastic nail was temporarily positioned in the screws unilaterally to achieve partial correction while the contralateral side was instrumented. Then, the TFR was removed and replaced with a permanent rod. Thirty-four patients with severe spinal deformities underwent posterior spinal fusion. Seventeen had scoliosis (mean major Cobb angle, 89.3°) and 17 had kyphosis (mean T5-T12 kyphosis, 73.8°). Idiopathic deformity was the most common etiology; neuromuscular, syndromic, and postsurgical causes contributed to the remainder of cases. All patients had Ponte osteotomies. Four patients (11.8%) had neuromonitoring alerts, 1 of which was related to insertion of the TFR; all were reversible. For patients with scoliosis, the mean postoperative Cobb angle measured 40.2° (53.6% correction). For patients with kyphosis, the mean postoperative T5-T12 angle measured 43.3° (30.4° of correction). TFRs appear to be helpful adjuncts for correction of severe pediatric spinal deformities, facilitating gradual intraoperative correction in a single-stage operation. Neuromonitoring alerts are common but reversible. [Orthopedics. 2023;46(4):234-241.].

Knowledge and Practices Related to Hip-Healthy Swaddling for Newborns Among Maternity Nurses.

OBJECTIVE: To assess the self-reported knowledge, education, and practices related to hip-healthy swaddling of newborns among nurses, how they teach this technique to parents, and the relationships among these factors. DESIGN: Descriptive cross-sectional exploratory survey. SETTING: Academic women and children's hospital with an average of 4,500 annual births. PARTICIPANTS: One hundred four registered maternity nurses who work primarily in the maternity unit. METHODS: At three staff meetings, we surveyed maternity nurses to determine their knowledge, education, and practices related to hip-healthy swaddling and how they teach this technique to parents. We analyzed results using descriptive statistics and chi-square and Fisher's exact tests. RESULTS: Of the 156 nurses in the maternity unit, 104 attended three staff meetings and completed the survey. Among the participants, 18.9% (18/95; 9 participants did not respond) were unable to identify the correct hip swaddling position. Overall, 64.2% (61/95; 9 participants did not respond) reported that they received education on general swaddling technique, yet 14.8% (9/61) of these participants were unable to identify the correct hip-healthy swaddling position. Among the participants, 99.0% (103/104) reported that nurses teach parents how to swaddle infants rather than other health care providers; 12.5% (13/104) of participants responded that medical doctors provide training as well. Overall, 67.0% (69/103; 1 participant did not respond) reported that they taught parents in >75% of parent interactions. CONCLUSION: Our results illustrate a gap in knowledge about hip-healthy swaddling among the maternity nurses who participated in this survey and a need for further education.

Curve Characteristics and Surgical Outcomes in Scoliosis Associated With Childhood Sternotomy or Thoracotomy.

BACKGROUND: The purpose of this study is to describe curve characteristics and postoperative outcomes in patients undergoing spinal fusion (SF) to treat thoracogenic scoliosis related to sternotomy and/or thoracotomy as a growing child. METHODS: A retrospective review of electronic medical records of all patients with Post-Chest Incision scoliosis treated with SF was performed at 2 tertiary care pediatric institutions over a 19-year period. Curve characteristics, inpatient, and outpatient postoperative outcomes are reported. RESULTS: Thirty-nine patients (62% female) were identified. Eighteen had sternotomy alone, 14 had thoracotomy alone, and 7 had both. Mean age at the time of first chest wall surgery was 2.5 years (range: 1.0 d to 14.2 y). Eighty-five percent of patients had a main thoracic curve (mean major curve angle 72 degrees, range: 40 to 116 degrees) and 15% had a main lumbar curve (mean major curve angle 76 degrees, range: 59 to 83 degrees). Mean thoracic kyphosis was 40 degrees (range: 4 to 84 degrees). Mean age at the time of SF was 14 years (range: 8.2 to 19.9 y). Thirty-six patients had posterior fusions and 3 had combined anterior/posterior. Mean coronal curve correction measured at the first postoperative encounter was 53% (range: 9% to 78%). There were 5 (13%) neuromonitoring alerts and 2 (5%) patients with transient neurological deficits. Mean length of hospital stay was 9±13 days. At an average follow-up time of 3.1±2.4 years, 17 complications (10 medical and 7 surgical) were noted in 9 patients for an overall complication rate of 23%. There was 1 spinal reoperation in the cohort. 2/17 (12%) complications were Clavien-Dindo-Sink class III and 5/17 (29%) were class IV. CONCLUSION: Kyphotic thoracic curves predominate in patients with Post-Chest Incision scoliosis undergoing SF. Although good coronal and sagittal plane deformity can be expected after a fusion procedure, postoperative complications are not uncommon in medically complex patients, often necessitating longer postoperative stays. LEVEL OF EVIDENCE: Level III.

Innovative technique for early-onset scoliosis casting using Jackson table.

PURPOSE: Early-onset scoliosis (EOS) can have harmful effects on pulmonary function. Serial elongation, derotation, and flexion (EDF) casting can cure EOS or delay surgical intervention. Most described casting techniques call for specialized tables, which are not available at many institutions. We describe an innovative technique for EDF casting utilizing a modified Jackson table (MJ) and compare results to a Risser frame (RF). METHODS: All patients who underwent EDF casting at our institution between January 2015 and January 2019 were identified and retrospectively reviewed. Patients were stratified by type of table used and clinical and radiographic outcomes were compared. Standard descriptive statistics were calculated. RESULTS: We identified 25 patients who underwent 77 casting events, 11 on an MJ table and 14 on a RF. Mean follow-up was 32 months (range 11-61 months). 28% of patients had idiopathic scoliosis. There was no significant difference in age at initiation of casting (P = 0.3), initial Cobb angle (equivalence, P = 0.009), or rate of idiopathic scoliosis between the MJ and RF groups. There was no significant difference in initial coronal Cobb angle percent correction (equivalence, P = 0.045) or percent correction at 1-year follow-up (equivalence, P = 0.010) between the two groups. There was no difference in cast related complications. There was a significant difference in surgical time, with the MJ group 11 min shorter than the RF (P = 0.005). CONCLUSION: The MJ table is a safe and effective alternative for applying EDF casts under traction without the need for a specialized table. LEVEL OF EVIDENCE: III.

Better Patient Care Through Physician Extenders and Advanced Practice Providers.

Physician extenders and advanced practice providers (APPs) are now common in most adult and pediatric orthopaedic clinics and practices. Their utilization, with physician leadership, can improve patient care, patient satisfaction, and physician satisfaction and work/life balance in addition to having financial benefits. Physician extenders can include scribes, certified athletic trainers, and registered nurses, while APPs include nurse practitioners and physician assistants/associates. Different pediatric orthopaedic practices or divisions within a department might benefit from different physician extenders or APPs based on particular skill sets and licensed abilities. This article will review each of the physician extender and APP health care professionals regarding their training, salaries, background, specific skill sets, and scope of practice. While other physician extenders such as medical assistants, cast technicians, and orthotists/prosthetists have important roles in day-to-day clinical care, they will not be reviewed in this article. In addition, medical trainees, including medical students, residents, fellows, and APP students, have a unique position within some academic clinics but will also not be reviewed in this article. With the many different local, state, and national regulations, a careful understanding of the physician extender and APP roles will help clinicians optimize their ability to improve patient care.

An Update on the Accessibility and Quality of Online Information for Pediatric Orthopaedic Surgery Fellowships.

Introduction The internet is an important tool for applicants seeking information on pediatric orthopaedic surgery fellowship programs. Previous analysis of pediatric orthopaedic surgery fellowship websites demonstrated they were often inaccessible and incomplete. As such, the purpose of this study was to (1) perform an updated assessment of the accessibility and content of pediatric orthopaedic fellowship program websites and (2) compare the results to the previous study to discern temporal trends in website accessibility and quality.  Methods A list of pediatric orthopaedic fellowship programs was compiled from the San Francisco Match (SF Match) and the Pediatric Orthopaedic Society of North America (POSNA) online databases. All identified websites were evaluated for (1) accessibility and (2) the presence of 12 education and 12 recruitment criteria. These criteria were determined by prior fellowship website analyses and the needs of current fellowship applicants. Website accessibility and quality were compared with previously reported metrics. Results Approximately 91% of pediatric orthopaedic surgery fellowship programs had a functioning website. While the SF Match and POSNA databases listed nearly identical programs, there were discrepancies in the information provided by the two databases, and individual program website links provided on both databases were often nonfunctional. Fellowship program websites contained an average of 15.1 ± 3.9 total education and recruitment criteria (range: 3 - 21). The most common education criteria featured on program websites included information about research, affiliated hospital information, and rotations. The most common recruitment criteria featured on program websites included program descriptions, contact information, and social media links. There was an increased frequency in nearly all education and recruitment criteria evaluated when compared with 2014 metrics.  Discussion Although website accessibility and content have improved since 2014, information on pediatric orthopaedic fellowship program websites remains incomplete, with many websites failing to provide information on criteria deemed important by fellowship applicants. In addition, many discrepancies exist between the SF Match and POSNA databases, the two primary sources of information for pediatric orthopaedic fellowship applicants. Increased consistency on pediatric orthopaedic fellowship websites and both the SF Match and POSNA databases may help applicants to better assess which programs to apply to and which programs to rank highly on their match list.

Health and Economic Outcomes of Posterior Spinal Fusion for Children With Neuromuscular Scoliosis.

OBJECTIVES: Neuromuscular scoliosis (NMS) can result in severe disability. Nonoperative management minimally slows scoliosis progression, but operative management with posterior spinal fusion (PSF) carries high risks of morbidity and mortality. In this study, we compare health and economic outcomes of PSF to nonoperative management for children with NMS to identify opportunities to improve care. METHODS: We performed a cost-effectiveness analysis. Our decision analytic model included patients aged 5 to 20 years with NMS and a Cobb angle ≥50°, with a base case of 15-year-old patients. We estimated costs, life expectancy, quality-adjusted life-years (QALYs), and incremental cost-effectiveness from published literature and conducted sensitivity analyses on all model inputs. RESULTS: We estimated that PSF resulted in modestly decreased discounted life expectancy (10.8 years) but longer quality-adjusted life expectancy (4.84 QALYs) than nonoperative management (11.2 years; 3.21 QALYs). PSF costs $75 400 per patient. Under base-case assumptions, PSF costs $50 100 per QALY gained. Our findings were sensitive to quality of life (QoL) and life expectancy, with PSF favored if it significantly increased QoL. CONCLUSIONS: In patients with NMS, whether PSF is cost-effective depends strongly on the degree to which QoL improved, with larger improvements when NMS is the primary cause of debility, but limited data on QoL and life expectancy preclude a definitive assessment. Improved patient-centered outcome assessments are essential to understanding the effectiveness of NMS treatment alternatives. Because the degree to which PSF influences QoL substantially impacts health outcomes and varies by patient, clinicians should consider shared decision-making during PSF-related consultations.

Day of the Week of Surgery Affects Time to Discharge for Patients With Adolescent Idiopathic Scoliosis.

Unnecessary delays in discharge are extraordinarily common in the current US health care system. These delays are even more protracted for patients undergoing orthopedic procedures. A traditional hospital staffing model is heavily weighted toward increased resources on weekdays and minimal coverage on the weekend. This study examined the effect of this traditional staffing model on time to discharge for patients undergoing posterior spinal instrumentation and fusion for adolescent idiopathic scoliosis. Patients undergoing surgery later in the week had a significantly longer hospital stay compared with patients undergoing surgery early in the week (5.5 days vs 4.9 days, respectively; P=.003). This discrepancy resulted in a mean cost increase of $7749.50 for patients undergoing surgery later in the week. A subsequent quality, safety, value initiative (QSVI) was undertaken to balance physical therapy resources alone. Following the QSVI, patients undergoing surgery later in the week had a decreased mean length of stay of 3.78 days (P=.002). Patients undergoing fusion early in the week also had a decreased mean length of stay of 3.66 days (P<.001). There was no longer a significant difference in length of stay between the "early" and the "late" groups (P=.84). This study demonstrates that simply having surgery later in the week in a hospital with a traditional staffing model adversely affects the timing of discharge, resulting in a significantly longer and more costly hospital course. By increasing physical therapy availability on the weekend, the length of stay and the cost of hospitalization decrease precipitously for these patients. [Orthopedics. 2020; 43(1);8-12.].

Treatment in a Nonpediatric Hospital Is a Risk Factor for Open Reduction of Pediatric Supracondylar Humerus Fractures: A Population-Based Study.

OBJECTIVES: To describe the distribution of open versus closed treatment and its relationship with the location of care in pediatric specialty versus general hospitals. METHODS: Patient data were extracted from the Healthcare Cost and Utilization Project's Kid's Inpatient Database for the years 2000-2012. ICD9-CM diagnosis and procedure codes were used to identify open versus closed treatment of closed supracondylar humerus fractures in children younger than 12 years. A multilevel logistic regression model to control for confounders and identify drivers of open treatment was used. RESULTS: An estimated 40,706 inpatient surgical fixation procedures met our inclusion criteria. Overall rate of open treatment was 13.65%. Fractures were less likely to be treated open at pediatric hospitals versus general hospitals 7.61% versus 16.13% (P < 0.0001). Over the study period, rates of open treatment have fallen at nonpediatric hospitals from 20.21% in 2000 to 17.42% in 2012 (P < 0.001) but have remained stable at pediatric hospitals: 7.8% in 2000 and 8.62% in 2012 (P = 0.4369). Mean hospital length of stay was higher for patients who had open treatment 1.63 versus 1.20 days (P < 0.0001), and mean hospital charges were higher for patients who had open treatment $21,465 versus $15,026 (P < 0.0001). After controlling for time trends as well as demographic and hospital characteristics with a logistic regression model, treatment at a nonpediatric hospital was the single most significant predictor of open treatment for an isolated closed supracondylar humerus fractures with an odds ratio of 1.96 (95% confidence interval 1.56-2.46; P < 0.001). CONCLUSIONS: In this comprehensive population-based study of risk factors for open treatment of supracondylar humerus fractures in the United States, we identified differences in practice patterns by hospital type. Pediatric supracondylar fractures of the elbow have almost twice the odds of open treatment at nonpediatric hospitals. LEVEL OF EVIDENCE: Prognostic Level III.

Trans-Metaphyseal Screws Placed in Children: An Argument for Monitoring and Potentially Removing the Implants.

BACKGROUND: Surgeons frequently use trans-metaphyseal screws in children to achieve osteosynthesis after fractures or stability after reconstructive osteotomies. Screws that were initially inserted below the cortex of bone can become prominent and symptomatic due to the process of funnelization that narrows the wide metaphysis to the diameter of the thinner diaphysis. METHODS: Case series presentation of 11 children who presented with screw prominence after the cutback process range in age from 19 to 169 months. We used the screws as radiographic markers to quantitate the amount of bone "cutback" or lost during the process of funnelization. RESULTS: The average length of screw protrusion beyond the edge of the bone when symptomatic was 8.7 mm (range, 3.3 to 14.3 mm). Time from implantation to the last radiograph averaged 40 months (range, 19 to 84 mo). The average loss of bone width at the time of presentation was 21% (range, 7% to 36%). CONCLUSIONS: These cases suggest that orthopaedic surgeons should consider monitoring children after implantation of trans-metaphyseal screws and informing parents and patients about the possibility of screw prominence necessitating removal due to the process of metaphyseal funnelization. LEVEL OF EVIDENCE: Level IV.

Endoscopic-assisted epiphysiodesis: technique and 20-year experience.

The aim of the study was to describe the endoscopic-assisted epiphysiodesis technique and review our 20-year experience with it. A retrospective review of 44 patients who underwent proximal tibia and/or distal femur endoscopic-assisted epiphysiodesis was carried out. Only patients who had preoperative and postoperative scanograms with clinical follow-up of at least 6 months were included. The mean length of follow-up was 36.8 months. All patients had radiographic evidence of physeal fusion within 6-12 months from the index procedure. No patient required revision surgery. Endoscopic-assisted epiphysiodesis is safe, effective, and achieves predictable physeal fusion. Advantages over current techniques include reduced radiation exposure and lack of requirement for hardware placement.

Adolescent idiopathic scoliosis: should 100% correction be the goal?

INTRODUCTION: What constitutes optimal thoracic curve scoliosis correction is controversial. The development and application of powerful pedicle screw-aided instrumentation constructs has, in some cases, led to hypercorrection of the thoracic scoliosis with resulting coronal imbalance, trunk shift, and shoulder imbalance. The purpose of this study was to compare the clinical and radiographic outcomes between Lenke 1 patients with the highest and lowest degree of correction to assess this risk. Our hypothesis was that greater scoliosis curve correction can be done without producing secondary decompensation. METHODS: Using a prospective AIS database, Lenke 1 curves, with 2-year follow-up (n=385) were ranked by percent coronal correction. The top 15% or high correction group (>80% coronal correction) were compared with the bottom 15% or low correction group (< 40% coronal correction). Clinical and radiographic outcomes, including parameters of coronal and sagittal balance, were compared using ANOVA and χ tests (P ≤ 0.007). RESULTS: The high correction group (n=39) and the low correction group (n=40) did not differ preoperatively except in lumbar flexibility. In the coronal plane, the high correction group did not show postoperative clinical imbalance (trunk shift and shoulder height) and had better radiographic balance (C7-CSVL shift). The deformity-flexibility quotient (DFQ), which is the ratio of residual lumbar curve to remaining unfused lumbar segments, was lower (optimal) in the high correction group. The residual rib hump was also better. In the sagittal plane, the high correction group had less kyphosis secondary to a loss of kyphosis compared with a gain (improvement) in the low correction group. Despite these differences, SRS scores were not different. CONCLUSIONS: Maximizing Lenke 1 curve correction to achieve greater lumbar correction and improved clinical appearance can be done without compromising coronal balance but may occur at the expense of sagittal alignment. However, surgeons who are learning to apply powerful new corrective methods should be cautious in trying to obtain full correction. Proper preoperative evaluation, fusion level selection, and surgical technique are needed to attain this outcome.

Management of spinal deformity in cerebral palsy.

An understanding of the three-dimensional components of spinal deformity in children with cerebral palsy is necessary to recommend treatments that will positively affect these patients' quality of life. Management of these deformities can be challenging and orthopedic surgeons should be familiar with the different treatments available for this patient population. This article discusses the incidence, causes, natural history, and treatment of patients with scoliosis.

Is ultrasound screening for DDH in babies born breech sufficient?

PURPOSE: To review our incidence of developmental dysplasia of the hip (DDH) in breech infants referred for ultrasound screening and to determine if subsequent follow-up radiographs are necessary in these patients with normal clinical and ultrasound examinations. METHODS: A review of the clinical data and imaging studies of all children with the risk factor of breech presentation that were referred for orthopedic evaluation over a 5-year period was conducted. All patients were examined by a fellowship-trained pediatric orthopedic surgeon and all ultrasounds were done at approximately 6 weeks of age by an experienced ultrasonographer. Ultrasounds were evaluated using the dynamic method as described by Harcke. As per our protocol, all patients with normal screening ultrasounds were brought back for a final clinical examination and radiographic check at 4-6 months. Acetabular dysplasia was indicated by radiographic parameters-if there was severe blunting of the sourcil, abnormal acetabular index for age, or if there was significant asymmetry of acetabular indices side-to-side-in the setting of clinical parameters-if there was greater than 10° difference in side-to-side abduction or symmetric abduction of less than 60°. RESULTS: Three hundred patients with the risk factor of breech presentation were included. Thirty-four patients had clinically unstable hips; 266 had clinically stable hips and were screened by ultrasound. Sixty-four percent were female and 36% were male. Twenty-seven percent of these breech patients had abnormal screening ultrasounds and were subsequently treated. Of the remaining 73% with normal ultrasounds, who were returned per protocol at a mean of 5 months, 29% had evidence of dysplasia and underwent treatment. The diagnosis of dysplasia following a normal ultrasound was based on both radiographic and clinical parameters. Of the hips treated with a Pavlik harness, 62% had acetabular indices at least two standard deviations from the age-corrected average versus 26% of patients not treated. The average length of follow-up was 10 months. CONCLUSIONS: Retrospectively, we found that, at approximately 6 weeks of age, ultrasound screening of breech patients with clinically stable hips produces an incidence of DDH of 27%. In those patients with a normal ultrasound, 29%, at 4-6 months radiographic follow-up, were found to have dysplasia requiring treatment. This data supports breech as the most important risk factor for hip dysplasia and we, therefore, recommend careful and longitudinal evaluation of these patients with: a careful newborn physical examination, an ultrasound at age 6 weeks, and an anteroposterior (AP) pelvis and frog lateral radiograph at 6 months, as the risk of subsequent dysplasia is too high to discharge patients after a normal ultrasound.
