Return to the Operating Room for Unplanned Pin Removal After Percutaneous Pinning of Supracondylar Humerus Fractures: A Retrospective Review.

BACKGROUND: Pin migration is a common complication associated with closed reduced and percutaneous pinning (CRPP) of supracondylar humerus fractures (SCHF) in children. Though this complication occurs frequently, little work has been done to elicit circumstances surrounding this complication. The purpose of this study was to evaluate patients with SCHF treated with percutaneous pins who needed to return to the operating room for pin removal. METHODS: This was a multicenter study involving children treated at 6 pediatric tertiary care centers between 2010 and 2020. Retrospective chart review was performed to identify children aged 3 to 10 years of age with a diagnosis of a SCHF. Current Procedural Terminology (CPT) codes were used to identify patients who underwent CRPP of their injuries. CPT codes for deep hardware removal requiring procedural sedation or anesthesia were used to identify patients who needed to return to the operating room for hardware removal. RESULTS: Between 2010 and 2020, 15 out of 7862 patients who were treated for SCHF at our 6 participating study centers experienced pin migration requiring a return to the operating room for pin removal, yielding a complication rate of 0.19%. Twelve (80%) of these injuries were Wilkins modification of the Gartland classification Type III, while the remaining injuries were Type II. 2-pin fixation constructs were used in nine (60%) children; 3-pin fixation constructs were used in 6 (40%) children. Pin migration was noted 23.2±7.0 days postoperatively at clinic follow-up. Four patients were noted to have multiple pins buried at follow-up. Four patients required 1-centimeter incisions for exposure of the buried pins, while surgeons were able to remove the buried pin with just a needle driver and blunt dissection in the remainder of patients. CONCLUSIONS: Pin migration is a common complication of closed reduction and percutaneous pinning of SCHF. There is variation in pin site management to prevent migration in the absence of underlying risk factors. LEVEL OF EVIDENCE: Level III.

Trends in Management of Pediatric Distal Radius Buckle Fractures.

BACKGROUND: Distal radius buckle fractures (DRBFx) represent nearly half of the pediatric wrist injuries. DRBFx are stable injury patterns that can typically be successfully managed with brief immobilization. The purpose of this study was to evaluate opinions and preferences of pediatric orthopaedic specialists regarding the management of DRBFx. METHODS: The POSNA Trauma Quality, Safety, and Value Initiative (QSVI) Committee developed a 20-question survey regarding the treatment of DRBFx in children. The survey was sent twice to all active and candidate POSNA members in June 2020 (n=1487). Questions focused on various aspects of treatment, including type and length of immobilization, follow-up, and radiographs and on potential concerns regarding patient/family satisfaction and pain control, medicolegal concerns, misdiagnosis, and mismanagement. RESULTS: A total of 317 participants completed the survey (response rate=21.3%). In all, 69% of all respondents prefer to use a removable wrist splint, with 76% of those in practice <20 years preferring removable wrist splints compared with 51% of those in practice >20 years (χ 2 =21.7; P <0.01). Overall, 85% of participants utilize shared decision-making in discussing management options with patients and their families. The majority of participants felt that the risk of complications associated with DRBFx was very low, but concern for misdiagnosis and mismanagement have required some respondents to perform closed or open reductions. CONCLUSIONS: In 2020, the majority of respondents treat DRBFx with removable splints (69%) for 3 or fewer weeks (55%), minimal follow-up (85%), and no reimaging (64%). This marks a dramatic shift from the 2012 POSNA survey when only 29% of respondents used removable splinting for DRBFx. LEVEL OF EVIDENCE: Level II.

Patient satisfaction surveys: an evaluation of POSNA members' knowledge and experience.

BACKGROUND: Patient satisfaction surveys (PSS) were originally designed to identify areas in need of improvement in patient interactions for individuals, practices, and institutions. As a result of the Affordable Care Act, the Centers for Medicare and Medicaid Services incorporated PSS into a formula designed to determine the quality of medical care delivered to hospital inpatients; the resultant score and rank will determine subsequent hospital payments. This survey was developed to evaluate POSNA members' knowledge of and experience with PSS. METHODS: The POSNA Practice Management Committee developed a 14-question survey that was sent to all active and candidate members (850). A total of 229 members responded; and results were tabulated by answer and simple percentages were calculated for each question. Comments were reviewed and grouped by similarity to identify frequency. RESULTS: A total of 82% of respondents were aware of PSS with 67% stating they were utilized in their setting. Utilization of PSS rarely alters clinical decision making. However, PSS do affect decisions regarding the patient experience; and 45% of respondents believe that PSS have utility with respect to business decisions. Fifty-nine percent of respondents feel that scores can be predictably improved. Less than half the respondents stated that they had a good or excellent understanding of PSS and only 48% believe that PSS are a valid measure of health care quality. CONCLUSIONS: POSNA members' knowledge of and experience with PSS are not universal or uniform. Although most agree that patient satisfaction does not drive clinical decision making, it does appear to impact business and clinic-flow decisions with the idea that it can be predictably improved. Despite this, members' self-assessed that knowledge is average and it is not clear to the members that patient satisfaction reflects medical quality. On the basis of these findings and as the impacts of PSS become more prominent, efforts to educate the members of POSNA about PSS should be enhanced. Furthermore, research to identify and develop best practices that enhance patient satisfaction and well-being while minimizing costs should be supported. LEVEL OF EVIDENCE: Level IV.

Emergency department on-call status for pediatric orthopaedics: a survey of the POSNA membership.

BACKGROUND: The emergency room on-call status of pediatric orthopaedic surgeons is an important factor affecting their practices and lifestyles and was last evaluated in 2006. METHODS: The entire membership of the Pediatric Orthopaedic Society of North America (POSNA) was surveyed in 2010 for information regarding their emergency room on-call status with 382 surveys returned of over 1000 e-mailed to members of POSNA. Detailed information about on-call coverage, support, and frequency was obtained in answers to 14 different questions. RESULTS: Compared with the prior survey in 2006, the 2010 survey indicated that a higher percentage of pediatric orthopaedic surgeons receive compensation for taking emergency room call; a higher percentage cover pediatric patients only when on-call; and accessibility to operating rooms in a timely manner for trauma cases, although limited, has improved for pediatric patients. Utilization of support staff to meet on-call trauma coverage demands, such as residents, physician's assistants, and nurse practitioners, is becoming more common. CONCLUSIONS: Concentration of pediatric orthopaedic trauma has increased the coverage demands on pediatric orthopaedists. This has resulted in a change in reimbursement strategies, and allocation of OR time and hospital staffing resources.

BrAIST-Calc: Prediction of Individualized Benefit From Bracing for Adolescent Idiopathic Scoliosis.

STUDY DESIGN: Prospective multicenter study data were used for model derivation and externally validated using retrospective cohort data. OBJECTIVE: Derive and validate a prognostic model of benefit from bracing for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: The Bracing in Adolescent Idiopathic Scoliosis Trial (BrAIST) demonstrated the superiority of bracing over observation to prevent curve progression to the surgical threshold; 42% of untreated subjects had a good outcome, and 28% progressed to the surgical threshold despite bracing, likely due to poor adherence. To avoid over-treatment and to promote patient goal setting and adherence, bracing decisions (who and how much) should be based on physician and patient discussions informed by individual-level data from high-quality predictive models. MATERIALS AND METHODS: Logistic regression was used to predict curve progression to <45° at skeletal maturity (good prognosis) in 269 BrAIST subjects who were observed or braced. Predictors included age, sex, body mass index, Risser stage, Cobb angle, curve pattern, and treatment characteristics (hours of brace wear and in-brace correction). Internal and external validity were evaluated using jackknifed samples of the BrAIST data set and an independent cohort (n=299) through estimates of discrimination and calibration. RESULTS: The final model included age, sex, body mass index, Risser stage, Cobb angle, and hours of brace wear per day. The model demonstrated strong discrimination ( c -statistics 0.83-0.87) and calibration in all data sets. Classifying patients as low risk (high probability of a good prognosis) at the probability cut point of 70% resulted in a specificity of 92% and a positive predictive value of 89%. CONCLUSION: This externally validated model can be used by clinicians and families to make informed, individualized decisions about when and how much to brace to avoid progression to surgery. If widely adopted, this model could decrease overbracing of AIS, improve adherence, and, most importantly, decrease the likelihood of spinal fusion in this population.

Adolescents with spondylolysis have lower SRS-22 scores than controls and peers with pre-operative idiopathic scoliosis.

PURPOSE: The Scoliosis Research Society Outcomes Questionnaire (SRS-22) is a health-related quality-of-life (HRQL) tool for scoliosis patients. Since no equivalent questionnaire exists for spondylolysis patients, we characterized patient-reported scores in pediatric spondylolysis patients using the SRS-22, and compared these scores to previously published values for age-matched controls and patients with pre-operative adolescent idiopathic scoliosis (AIS). METHODS: A single-institution cross-sectional observational study was performed using SRS-22 data from spondylolysis patients aged 12-18 years. Mean SRS-22 domain scores were compared to the existing literature values for adolescent control and AIS cohorts via unpaired Student t tests (α = 0.05) and against minimal clinically important differences (MCIDs). RESULTS: Thirty-five patients met inclusion criteria. Mean (± SD) spondylolysis patients' scores met the MCID across all domains except Mental Health (α= 0.05). Spondylolysis patient scores for Pain, Function, and Self-Image were significantly lower (p < 0.01) than AIS patients (Pain; 2.99 ± 0.66 vs 4.14 ± 0.79; Function; 3.81 ± 0.61 vs 4.09 ± 0.54; Self-Image; 3.45 ± 0.70 vs 3.80 ± 0.68). CONCLUSION: The adolescent spondylolysis population has clinically significantly lower SRS-22 scores compared to age-matched controls and AIS patients, suggesting that the SRS-22 questionnaire should be given to this population to assess patients' HRQL. Further research is needed to assess the utility of the SRS-22 in measuring treatment effects. LEVEL OF EVIDENCE: III.

Scoliosis Research Society survey: brace management in adolescent idiopathic scoliosis.

PURPOSE: While the Scoliosis Research Society (SRS) has established criteria for brace initiation in adolescent idiopathic scoliosis (AIS), there are no recommendations concerning other management issues. As the BrAIST study reinforced the utility of bracing, the SRS Non-Operative Management Committee decided to evaluate the consensus or discord in AIS brace management. METHODS: 1200 SRS members were sent an online survey in 2017, which included 21 items concerning demographics, bracing indications, management, and monitoring. Free-text responses were analyzed and collated into common themes. Data were analyzed using Microsoft Excel 2013. RESULTS: Of 218 respondents; 207 regularly evaluate and manage patients with AIS, and 205 currently prescribe bracing. 99% of respondents use bracing for AIS and the majority (89%) use the published SRS criteria, or a modified version, to initiate bracing. 85% do not use brace monitoring and 66% use both %-Cobb correction and fit criteria to evaluate brace adequacy. In contrast, other aspects of brace management demonstrated a high degree of practice variability. This was seen with a radiographic assessment of maturity level, hours prescribed, timing and frequency of radiographic evaluation, the use of nighttime bracing only, and the method and timing of brace discontinuation. CONCLUSION: Although there is consensus in brace management amongst SRS members with respect to brace initiation and evaluation of adequacy, there is striking variability in how bracing for AIS is used. This variability may impact the overall efficacy of brace treatment and may be decreased with more robust guidelines from the SRS. LEVEL OF EVIDENCE: III.

Intraoperative neuromonitoring practice patterns in spinal deformity surgery: a global survey of the Scoliosis Research Society.

PURPOSE: Although multimodal IONM has reached a widespread use, several unresolved issues have remained in clinical practice. The aim was to determine differences in approaches to form a basis for taking actions to improve patient safety globally. METHODS: A survey comprising 19 questions in four sections (demographics, setup, routine practices and reaction to alerts) was distributed to the membership of the SRS. RESULTS: Of the estimated 1300 members, 205 (~ 15%) completed the survey. Respondent demographics reflected SRS member distribution. Most of the respondents had > 10 years of experience. TcMEP and SSEP were available to > 95%. Less than 5% reported that a MD/PhD with neurophysiology background routinely examines patients preoperatively, while 19% would consult if requested. After an uneventful case, 36% reported that they would decrease sedation and check motor function if the patient was to be transferred to ICU intubated. Reactions to dropped signals that recovered or did not fully recover varied between attempting the same correction to aborting the surgery with no rods and returning another day, with or without implant removal. After a decrease of signals, 85.7% use steroids of varied doses. Of the respondents, 53.7% reported using the consensus-created checklist by Vitale et al. Approximately, 14% reported never using the wake-up test while others use it for various conditions. CONCLUSION: The responses of 205 experienced SRS members from different regions of the world showed that surgeons had different approaches in their routine IONM practices and in the handling of alerts. This survey indicates the need for additional studies to identify best practices.

Multimodal pain control in adolescent posterior spinal fusion patients: a double-blind, randomized controlled trial to validate the effect of gabapentin on postoperative pain control, opioid use, and patient satisfaction.

STUDY DESIGN: Prospective double-blind, randomized controlled trial. OBJECTIVES: The objective of this study was to validate the efficacy of gabapentin as part of a multimodal pain regimen in a double-blind, randomized controlled trial for patients aged 10-19 years with idiopathic scoliosis undergoing posterior spinal fusion. Perioperative pain management represents a challenge for patients undergoing surgical correction of adolescent spinal deformity. Gabapentin has been shown to decrease postoperative pain and opioid use after spine surgery, but it has not yet been investigated as part of a multimodal pain regimen intended to decrease the perioperative use of opioids. METHODS: Fifty patients were randomized to receive gabapentin or placebo pre- and postoperatively in addition to a standardized medication regime including scheduled ketorolac and as-needed acetaminophen, hydromorphone, and oxycodone. Patients were monitored in the pre-, peri-, and postoperative periods for pain levels, medication dosing, side effects, adverse events, hospitalization length of stay, and parent satisfaction. RESULTS: There were statistically significant decreases in early postoperative pain scores and opioid use as well as total postoperative opioid use for the treatment group relative to controls. There were no statistically significant differences in adverse events, medication side effects, or hospitalization length. Parents of patients in both groups were very satisfied with the pain control provided to their children. CONCLUSIONS: This randomized controlled trial demonstrates that pre- and postoperative administration of gabapentin as part of a multimodal pain management protocol significantly decreases both opioid use and visual analog pain scales in the first two postoperative days after posterior spinal fusion for adolescent idiopathic scoliosis. Gabapentin should be considered as a standard medication for perioperative pain control in this patient population. LEVEL OF EVIDENCE: Level I.

Utility of Follow-up Radiographs After Pin Removal in Supracondylar Humerus Fractures: A Retrospective Cohort Study.

INTRODUCTION: Displaced supracondylar humerus fractures (SCFs) are common pediatric injuries, typically treated by closed reduction and percutaneous pinning (CRPP). Radiographs are obtained at pin removal and subsequently to evaluate fracture healing. We evaluated the utility of radiographs obtained after pin removal in pediatric SCF management. METHODS: A retrospective cohort study of children aged 2 to 11 years with SCF requiring CRPP at a single institution from January 2007 to July 2017 was conducted. Radiographs were taken at pin removal and minimum 3 weeks later. Demographic and treatment data were collected via chart review. Radiographic measures were Baumann and lateral humeral-capitellar angles, anterior humeral line alignment, and number of cortices with callus. The McNemar-Bowker test analyzed anterior humeral line alignment and cortices with callus. The paired t-test analyzed Baumann and lateral humeral-capitellar angles. RESULTS: One hundred patients were included (47 males and 53 females, mean 5.7 years). The mean time to pin removal was 23.8 days, and the median clinical and radiographic follow-up periods were 109.0 and 52.2 days, respectively. Fracture patterns were extension type II (21%), III (73%), IV (1%), flexion (4%), and varus (1%). No patients' fracture management changed in the acute or long-term postoperative period because of findings on post-pin removal (PPR) radiographs. Fewer cortices with callus were seen at pin removal versus PPR (<0.001). At pin removal, no differences were found in the Baumann angle (75.8 ± 5.0 versus 74.6 ± 5.9; P = 0.053), lateral humeral-capitellar angles (30.7 ± 12.5 versus 31.6 ± 1.3; P = 0.165), or anterior humeral line alignment (P = 0.261). DISCUSSION: No patients' fracture management was modified because of findings evident on PPR radiographs. The number of cortices with callus was the only radiographic measure to differ over time, as is anticipated with routine healing. Elbow radiographic alignment measures did not differ in the interval between radiographs. Therefore, PPR radiographs may not provide clinical utility in the absence of other clinical findings. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Neurophysiological monitoring of spinal cord function during spinal deformity surgery: 2020 SRS neuromonitoring information statement.

The Scoliosis Research Society has developed an updated information statement on intraoperative neurophysiological monitoring of spinal cord function during spinal deformity surgery. The statement reviews the risks of spinal cord compromise associated with spinal deformity surgery; the statement then discusses the various modalities that are available to monitor the spinal cord, including somatosensory-evoked potentials, motor-evoked potentials, and electromyographic (EMG) options. Anesthesia considerations, the importance of a thoughtful team approach to successful monitoring, and the utility of checklists are also discussed. Finally, the statement expresses the opinion that utilization of intraoperative neurophysiological spinal cord monitoring in spinal deformity surgery is the standard of care when the spinal cord is at risk.

Bracing in Adolescent Idiopathic Scoliosis Trial (BrAIST): Development and Validation of a Prognostic Model in Untreated Adolescent Idiopathic Scoliosis Using the Simplified Skeletal Maturity System.

STUDY DESIGN: Prognostic study and validation using prospective clinical trial data. OBJECTIVE: To derive and validate a model predicting curve progression to ≥45° before skeletal maturity in untreated patients with adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Studies have linked the natural history of AIS with characteristics such as sex, skeletal maturity, curve magnitude, and pattern. The Simplified Skeletal Maturity Scoring System may be of particular prognostic utility for the study of curve progression. The reliability of the system has been addressed; however, its value as a prognostic marker for the outcomes of AIS has not. The BrAIST trial followed a sample of untreated AIS patients from enrollment to skeletal maturity, providing a rare source of prospective data for prognostic modeling. METHODS: The development sample included 115 untreated BrAIST participants. Logistic regression was used to predict curve progression to ≥45° (or surgery) before skeletal maturity. Predictors included the Cobb angle, age, sex, curve type, triradiate cartilage, and skeletal maturity stage (SMS). Internal and external validity was evaluated using jackknifed samples of the BrAIST data set and an independent cohort (n = 152). Indices of discrimination and calibration were estimated. A risk classification was created and the accuracy evaluated via the positive (PPV) and negative predictive values (NPV). RESULTS: The final model included the SMS, Cobb angle, and curve type. The model demonstrated strong discrimination (c-statistics 0.89-0.91) and calibration in all data sets. The classification system resulted in PPVs of 0.71-0.72 and NPVs of 0.85-0.93. CONCLUSIONS: This study provides the first rigorously validated model predicting a short-term outcome of untreated AIS. The resultant estimates can serve two important functions: 1) setting benchmarks for comparative effectiveness studies and 2) most importantly, providing clinicians and families with individual risk estimates to guide treatment decisions. LEVEL OF EVIDENCE: Level 1, prognostic.

High-grade spondylolisthesis treated using a modified Bohlman technique: results among multiple surgeons.

OBJECT: The ideal surgical management of high-grade spondylolisthesis remains unclear. Concerns regarding the original Bohlman transsacral interbody fusion technique with stand-alone autologous fibular strut include late graft fracture and incomplete reduction of lumbosacral kyphosis. The authors' goal was to evaluate the radiographic and surgical outcomes of patients treated for high-grade spondylolisthesis with either transsacral S-1 screws or standard pedicle screw fixation augmenting the Bohlman posterior transsacral interbody fusion technique. METHODS: A retrospective review of patients who underwent fusion for high-grade spondylolisthesis in which a Bohlman oblique posterior interbody fusion augmented with either transsacral or standard pedicle screw fixation was performed by 4 spine surgeons was completed. Estimated blood loss, operating time, perioperative complications, and need for revision surgery were evaluated. Upright pre- and postsurgical lumbar spine radiographs were compared for slip percent and slip angle. RESULTS: Sixteen patients (12 female and 4 male) with an average age of 29 years (range 9-66 years) were evaluated. The average clinical follow-up was 78 months (range 5-137 months) and the average radiographic follow-up was 48 months (range 5-108 months). Ten L4-S1 and 6 L5-S1 fusions were performed. Five fibular struts and 11 titanium mesh cages were used for interbody fusion. Six patients had isolated transsacral screws placed, with 2 (33%) of the 6 requiring revision surgery for nonunion. No nonunions were observed in patients undergoing spanning pedicle screw fixation augmenting the interbody graft. Six patients experienced perioperative complications including 3 iliac crest site infections, 1 L-5 radiculopathy without motor involvement, 1 deep vein thrombosis, and 1 epidural hematoma requiring irrigation and debridement. The average estimated blood loss and operating times were 763 ml and 360 minutes, respectively. Slip percent improved from an average of 62% to 37% (n = 16; p < 0.01) and slip angle improved from an average of 18° to 8° (n = 16; p < 0.01). No patient experienced L-5 or other motor deficit postoperatively. CONCLUSIONS: The modified Bohlman technique for treatment of high-grade spondylolisthesis has reproducible outcomes among multiple surgeons and results in significant improvements in slip percent and slip angle. Fusion rates were high (14 of 16; 88%), especially with spanning instrumentation augmenting the oblique interbody fusion. Rates of L-5 motor deficit were low in comparison with techniques involving reduction of the anterolisthesis.
