Is it necessary to use a cervical brace after single- or double-level ACDF?

Although anterior cervical discectomy and fusion (ACDF) is one of the most frequently performed spinal surgeries, there is no consensus regarding the necessity of prescribing a cervical brace after surgery. This study aimed to investigate any difference in radiological and clinical outcomes when wearing or not wearing cervical braces after single- or double-level ACDF. We examined 2 cohorts of patients who underwent single- or double-level ACDF surgery with and without a cervical brace: patients who underwent ACDF between March 2018 and December 2019 received a cervical brace, while patients who underwent ACDF between January 2020 and May 2021 did not. Each patient was evaluated radiologically and functionally using plain X-ray, modified Japanese Orthopedic Association score, and visual analog scale for neck and arm until 12 months after surgery. Fusion rate, subsidence, and postoperative complications were also evaluated. Eighty-three patients were included in the analysis: 38 were braced and 45 were not. The demographic characteristics and baseline outcome measures of both groups were similar. There was no statistically significant difference in any of the clinical measures at baseline. The modified Japanese Orthopedic Association score and visual analog scale for neck and arm were similar in both groups at all time intervals and showed statistically significant improvement when compared with preoperative scores. In addition, fusion rate, subsidence, and postoperative complications were similar in both groups. Our results suggest that the use of cervical braces does not improve the clinical outcomes of individuals undergoing single- or double-level ACDF.

Lumbar braces and other assistive devices for treatment of chronic low back pain.

OBJECTIVES: This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of assistive technologies (i.e. non-rigid and rigid lumbar braces, belts, supports, and devices to assist mobility and gait) for improving pain and function (and consequently reducing disability) in adults with chronic low back pain.

Comparison of brace to observation in stable, radiological developmental dysplasia of the hip: a protocol for a global multicentre non-inferiority randomised trial.

INTRODUCTION: Brace treatment is common to address radiological dysplasia in infants with developmental dysplasia of the hip (DDH); however, it is unclear whether bracing provides significant benefit above careful observation by ultrasound. If observation alone is non-inferior to bracing for radiological dysplasia, unnecessary treatment may be avoided. Therefore, the purpose of this study is to determine whether observation is non-inferior to bracing for infants with radiological dysplasia. METHODS AND ANALYSIS: This will be a multicentre, global, randomised, non-inferiority trial performed under the auspices of a global prospective registry for infants and children diagnosed with DDH. Patients will be included if they present with radiological dysplasia (centred hip, alpha angle 43-60°, percent femoral head coverage greater than 35% measured on ultrasound) of a clinically stable hip under 3 months old. Patients will be excluded if they present with clinical hip instability, have received prior treatment or have known/suspected neuromuscular, collagen, chromosomal or lower-extremity congenital abnormalities or syndromic-associated hip abnormalities. Patients will be enrolled and randomised to undergo observation alone or brace treatment with a Pavlik harness for a minimum of 6 weeks. Follow-up visits will occur at 6 weeks, 1 year and 2 years post-enrolment. The primary outcome will be the norm-referenced acetabular index measured on the 2-year radiograph with a 3° non-inferiority margin. A total of 514 patients will be included.The study is anticipated to start in April 2024 and end in September 2028.The primary outcome will be compared between arms with a mixed-effects model with a random intercept for study centre, and a single covariate for the treatment group. If the lower bound of the 95% CI lies within 3° of the mean, we will treat this as evidence for non-inferiority. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the lead site's ethics board (University of British Columbia, Children's and Women's Research Ethics Board). Ethics approval will be obtained from the local ethics committees or institutional review boards at each institution prior to patient enrolment. It is intended that the results of this study shall be published in peer-reviewed journals and presented at suitable conferences. TRIAL REGISTRATION NUMBER: NCT05869851.

Pectus Disorders: Excavatum, Carinatum and Arcuatum.

This article reviews pectus excavatum, carinatum, and arcuatum. Topics covered include etiology, epidemiology, associated syndromes, physiologic impact, workup, indications for treatment, surgical and nonsurgical therapy, results, complications, and emerging therapies. Pectus excavatum is an inward deformation of the sternum and/or anterior chest wall. Pectus carinatum is ether an outward protrusion or tilt of the sternum with potential psychological impact, but no demonstrated physiologic impact. Nonoperative compression bracing is successful in carinatum patients with chest wall flexibility who are compliant with a bracing program. Pectus arcuatum is an abnormally short, fully fused sternum with a high anterior protrusion.

Resolving residual acetabular dysplasia following successful brace treatment for developmental dysplasia of the hip in infants.

Aims: Radiological residual acetabular dysplasia (RAD) has been reported in up to 30% of children who had successful brace treatment of infant developmental dysplasia of the hip (DDH). Predicting those who will resolve and those who may need corrective surgery is important to optimize follow-up protocols. In this study we have aimed to identify the prevalence and predictors of RAD at two years and five years post-bracing. Methods: This was a single-centre, prospective longitudinal cohort study of infants with DDH managed using a published, standardized Pavlik harness protocol between January 2012 and December 2016. RAD was measured at two years' mean follow-up using acetabular index-lateral edge (AI-L) and acetabular index-sourcil (AI-S), and at five years using AI-L, AI-S, centre-edge angle (CEA), and acetabular depth ratio (ADR). Each hip was classified based on published normative values for normal, borderline (1 to 2 standard deviations (SDs)), or dysplastic (> 2 SDs) based on sex, age, and laterality. Results: Of 202 infants who completed the protocol, 181 (90%) had two and five years' follow-up radiographs. At two years, in 304 initially pathological hips, the prevalence of RAD (dysplastic) was 10% and RAD (borderline) was 30%. At five years, RAD (dysplastic) decreased to 1% to 3% and RAD (borderline) decreased to < 1% to 2%. On logistic regression, no variables were predictive of RAD at two years. Only AI-L at two years was predictive of RAD at five years (p < 0.001). If both hips were normal at two years' follow-up (n = 96), all remained normal at five years. In those with bilateral borderline hips at two years (n = 21), only two were borderline at five years, none were dysplastic. In those with either borderline-dysplastic or bilateral dysplasia at two years (n = 26), three (12%) were dysplastic at five years. Conclusion: The majority of patients with RAD at two years post-brace treatment, spontaneously resolved by five years. Therefore, children with normal radiographs at two years post-brace treatment can be discharged. Targeted follow-up for those with abnormal AI-L at two years will identify the few who may benefit from surgical correction at five years' follow-up.

Immediate vs Gradual Brace Weaning Protocols in Adolescent Idiopathic Scoliosis: A Randomized Clinical Trial.

Importance: Lack of evidence and consensus for brace weaning protocol in adolescent idiopathic scoliosis (AIS) results in clinicians prescribing gradual weaning in the hope of avoiding curve deterioration after weaning. However, gradual weaning contributes to prolonged brace wear, which can affect spinal stiffness and health-related quality of life (HRQoL). Objective: To determine whether gradual weaning results in better curve magnitude and truncal balance maintenance after brace weaning vs immediate brace removal for patients with AIS. Design, Setting, and Participants: This was an open-labeled randomized clinical trial commenced in April 2017 with 24-month follow-up completed in January 2023. Outcome assessors were masked to weaning protocol assigned. The study took place at a territory-wide tertiary scoliosis clinic serving the largest number of referrals in the local population. Patients with AIS ready to wean off of brace wear were eligible (402 were screened; 33 were excluded [15 for <18 hours/day of brace-wear compliance before weaning, 11 were treated with Milwaukee brace, and 7 declined to participate]; and 369 were included), and those who were treated with a custom molded thoracolumbosacral orthosis and had reached skeletal maturity were consecutively recruited. Interventions: Patients were randomized to gradual weaning protocol (n = 176) with an additional 6 months of nighttime wear before completely stopping or immediate weaning protocol (n = 193) with immediate brace removal at recruitment. Main Outcomes and Measures: Changes in major curve Cobb angle and truncal balance from the time of weaning to 6-month, 12-month, and 24-month follow-up. HRQoL was also assessed using the refined Scoliosis Research Society 22-item and EuroQol 5-dimension questionnaires. Results: A total of 369 patients (mean [SD] age, 14.9 [1.1] years; 304 [83.4%] girls) were randomized with 284 (77.0%) completing 24-month longitudinal follow-up. Immediate and gradual weaning groups had no significant differences in change of major Cobb angle at postweaning 6-month (difference, -0.6°; 95% CI, -1.4 to 0.2; P = .17), 12-month (difference, -0.3°; 95% CI, -1.2 to 0.6; P = .47), and 24-month (difference, -0.3°; 95% CI, -1.2 to 0.7; P = .60) follow-up. The number of curve progression, nonprogression, and rebound cases were comparable (χ22 = 2.123; P = .35). Postweaning changes in truncal balance and HRQoL demonstrated no significant differences between groups. Conclusions: Gradual weaning did not demonstrate superiority to immediate weaning with predefined criteria of Cobb angle and truncal balance maintenance and HRQoL after brace weaning. Gradual and immediate weaning achieved very similar maintenance of brace outcomes in AIS. We therefore recommend the consideration of immediate brace weaning, which aims to benefit patients with earlier time for increased exercises and activity level.

Adolescent Idiopathic Scoliosis: Increased Body Mass Associated with Decreased Bracing Outcomes.

Bracing reduces the need for surgical intervention in patients with adolescent idiopathic scoliosis (AIS). However, bracing outcomes with variable body mass index (BMI) are understudied. The authors sought to determine the association of BMI with bracing outcomes. The authors performed a retrospective cohort study of 104 patients presenting with AIS. Initial Risser score, hours of bracing per day, BMI percentile, and curve magnitude pre- and postbracing were collected. There was no detectable difference between years of brace wear or primary curve magnitude at time of presentation between both groups. Overall, 29% (25/87) of underweight/normal weight patients and 59% (10/17) of overweight/obese patients had curves ≥ 45 degrees at the end of bracing (p = 0.016). Odds of having a curve ≥ 45 degrees after bracing were 3.5 (95% confidence interval: 1.2 to 10.3, p = 0.021) times higher for overweight/obese patients compared with underweight/normal weight patients. Increased overlying adipose tissue may reduce the corrective forces required to straighten the spine. (Journal of Surgical Orthopaedic Advances 33(1):029-032, 2024).

Scapholunate Ligament Reconstruction With Internal Brace Augmentation Techniques for Chronic Scapholunate Dissociation: A Clinical Follow-up Study.

INTRODUCTION: The scapholunate ligament is the most important stabilizer of the scapholunate articulation. The management of chronic irreversible injuries of this ligament in the absence of preexisting arthritis of the wrist joint remains controversial. Recently, surgeons introduced a novel surgical technique using an internal brace (IB). Several biomechanical studies on this technique have been conducted using cadavers; however, very few studies have discussed the results in detail in actual clinical practice. Therefore, herein, we investigated the radiological and functional results of patients who underwent IB augmentation as a treatment for chronic scapholunate dissociation. METHODS: This retrospective study was conducted from April 2018 to May 2022. Twenty-two patients with chronic scapholunate dissociation were treated using the IB augmentation technique, of whom 17 were followed-up for at least 1 year. Radiological results, including scapholunate distance, scapholunate angle, and radioscaphoid angle, were collected. Furthermore, clinical parameters, such as the visual analog scale (preoperative and at final follow-up), the Disabilities of the Arm, Shoulder, and Hand scores (preoperatively and at 3, 6, and 12 months postoperatively), and Mayo wrist scores (preoperative and at final follow-up), were measured. RESULTS: The scapholunate distance increased significantly in the affected wrist compared to the unaffected wrist, which improved after reconstruction in all wrist positions ( P < 0.05). Compared to the unaffected wrist, the scapholunate angle increased significantly in all positions ( P < 0.05) except for extension ( P = 0.535) and improved after reconstruction in all wrist positions. The radioscaphoid angle significantly increased compared to the angle of the unaffected wrist in all positions ( P < 0.05) except for extension ( P = 0.602) and clenched fist ( P = 0.556). This angle improved after reconstruction in all wrist positions except for extension ( P = 0.900). The visual analog scale score (7-2, preoperatively and at final follow-up) and Mayo wrist score (53-82, preoperatively and at final follow-up) improved after surgery. The Disabilities of the Arm, Shoulder, and Hand scores also improved after surgery (68, 53, 30, 7, preoperatively and at 3, 6, and 12 months postoperatively). CONCLUSIONS: This study revealed that scapholunate ligament reconstruction using an autologous tendon and suture tape is a good reconstruction technique that can improve clinical symptoms and radiographic parameters with a shorter operation time and fewer complications than other reconstruction methods.

Iatrogenic open humeral shaft fractures following functional bracing.

INTRODUCTION: The treatment of closed humeral shaft fractures tends to be successful with functional bracing. Treatment failure due to iatrogenic conversion to an open fracture has not been described in the literature. We present a case series of patients that experienced open humeral shaft fractures after initially being treated with functional bracing for closed humeral shaft fractures and describe what factors are associated with this complication. MATERIALS AND METHODS: This was a retrospective case series performed at three level 1 trauma centers across North America. All nonoperatively treated humeral shaft fractures were reviewed from 2001 to 2023. Patients were included if they sustained a humeral shaft fracture, > 18 years old, were initially treated non-operatively with functional bracing which subsequently converted to an open fracture. Eight patients met inclusion criteria. All included patients were eventually treated with irrigation, debridement, and open reduction and internal fixation. Outcomes assessed included mortality rate, time until the fracture converted from closed to open, need for further surgery, and bony union. Descriptive statistics were used in analysis. RESULTS: The eight included patients on average were 65 ± 21.4 years old and had a body mass index (BMI) of 25.6 ± 5.2. Six patients were initially injured due to a fall. Time until the fractures became open on average was 5.2 ± 3.6 weeks. Three patients (37.5%) died within 1.8 ± 0.6 years after initial injury. The average Charlson Comorbidity Index (CCI) score was 4.5 ± 3.4. Three patients (37.5%) had dementia. Common characteristics among this cohort included a history of visual disturbances (50.0%), cerebrovascular accident (50.0%), smoking (50.0%), and alcohol abuse (50.0%). CONCLUSION: Conversion from a closed to open humeral shaft fracture after functional bracing is a potentially devastating complication. Physicians should be especially cognizant of patients with a low BMI, history of falling or visual disturbance, dementia, age ≥ 65, decreased sensorimotor protection, and significant smoking or alcohol history when choosing to use functional bracing as the final treatment modality. LEVEL OF EVIDENCE: IV.

Effects of Cervical Bracing on Elderly Patients With Dysphagia.

PURPOSE: This study aimed to determine if cervical bracing with a PMT collar increases risk of airway invasion and pharyngeal residue in elderly patients with dysphagia. Additionally, it aimed to identify patient preference for cervical bracing during deglutition. METHOD: Twenty-one patients underwent a videofluoroscopic swallow study. Thin liquid, nectar thick liquid, pudding, and cracker were administered with cervical collar on and off with order of condition randomized. The Penetration-Aspiration Scale (PAS) was used to grade swallows, with McNemar's test of symmetry used to determine whether the categorical PAS score was similar between conditions. Pharyngeal residue was measured following swallows. Patients were asked which condition they preferred, and which was more comfortable with "no difference" being a selection. RESULTS: No significant difference in PAS categorization score was measured for any consistency (p = .317-.919). Significantly more pyriform sinus residue was measured in the collar off condition (p = .003), albeit amounts were within normative range, with no difference measured in vallecula residue between conditions (p = .939). Forty-five percent of participants preferred to swallow with the collar off, while 55% indicated no preference. Forty-one percent of participants indicated increased comfort with collar off, while 59% indicated no difference in comfort. No participant preferred swallowing or indicated increased comfort with the collar on. CONCLUSIONS: Presence of a cervical collar in elderly patients with dysphagia did not result in a significant difference in airway invasion or total pharyngeal residue. There was significantly more residue in the pyriform sinuses when cervical bracing was removed. The majority of patients did not indicate a difference in preference or comfort between collar on/off conditions.

Do middle-aged patients with onset of idiopathic scoliosis before the age of 10 years who have reduced pulmonary function have a risk for rapid decline - a comparative study.

BACK GROUND: Knowledge concerning pulmonary function in adult patients with onset of idiopathic scoliosis before age 10 is sparse. A long-term follow-up (FU, mean 26 years, > 12 years after treatment) of pulmonary function (PF) in patients treated with brace or surgery due to idiopathic scoliosis with onset before the age of 10 was earlier performed. To evaluate whether a more severe reduction in pulmonary function leads to more rapid deterioration within a four-year period, this study was performed. METHODS: Twenty patients with the most reduced pulmonary function and 19 out of those with normal PF found at the long-term FU were reexamined 4 years later to evaluate further changes in pulmonary function. Patients underwent spirometry and arterial blood gas analysis and answered pulmonary symptom questionnaires. RESULTS: 70% of the reduced pulmonary function group had undergone surgery vs. 26% of the normal group. The mean age (47 vs. 43 years) at this FU and curve size (37° vs. 35°) at the 26-year FU were similar. The decline in forced vital capacity (FVC) % of predicted was similar in both groups over the four-year period, from 67 to 65% in the reduced PF group vs. 96 to 94% in the normal PF group. The total lung capacity (TLC) % of predicted did not change over time in either group. No patient reported worsening dyspnea symptoms. Only one patient in the reduced PF group showed low arterial oxygen tension, 8.4 kPa, not signifying respiratory insufficiency. CONCLUSION: The age-related decline in FVC and TLC % of predicted did not differ between those with reduced and those with normal pulmonary function at the 26-year follow-up. Thus, these data do not infer increased rate of decline in the most deteriorated patients.

The efficacy of bracing in the treatment of progressive early-onset scoliosis.

Serial casting as one of the applications to treat early-onset scoliosis has been reported efficiently to improve deformity, but no report has focused on the efficacy of braces in the treatment of congenital early-onset scoliosis and comparison with progressive idiopathic early-onset scoliosis. Patients with progressive EOS treated with braces in our institution with a minimum of 4 years follow-up were reviewed. Two groups according to the etiological diagnosis were analyzed and compared: the congenital scoliosis (CS) group and idiopathic scoliosis (IS) group. The success cases and the failure cases were also compared. 27 patients with an average main Cobb angle of 38.19° (20-55) underwent initial bracing at an average age of 55.7 months (24-108), the average follow-up time was 76.19 months (49-117). In IS group the main Cobb angle was corrected to 18.69 ± 12.06° (48.61%) following the first bracing; the final Cobb angle was 23.08 ± 22.15°(38.76%) after brace removal. In CS group the main Cobb angle was corrected to 33.93 ± 10.31°(17.1%) following the first bracing and 37.93 ± 14.74°(3.53%) after brace removal. Both coronal chest width and T1-T12 height increased dramatically from pre-bracing to the last follow-up. Patients diagnosed as IS tended to have a better result in main Cobb angle correction than that of CS (P = 0.049). By the time of last follow-up, 8 patients had undergone surgery, and the operation time was postponed by 68.88 ± 26.43 months. For patients with progressive early-onset scoliosis, bracing is an efficient nonsurgical alternative to casting, and some of them can be cured; if not, eventual surgical intervention can be delayed for a period of time without restrictions on the thoracic cavity.

Factors that influence in-brace derotation effects in patients with adolescent idiopathic scoliosis: a study based on EOS imaging system.

OBJECTIVE: To investigate the effects of bracing on apical vertebral derotation and explore the factors that influence in-brace derotation effects in adolescent idiopathic scoliosis (AIS) patients. For patients with AIS, vertebral rotation causes cosmetic appearance abnormalities and acts as an indicator for curve progression. However, there have been few studies investigating the precise derotation effects of bracing for apical vertebra. The application of EOS imaging system enables quantitative evaluation of vertebral rotation in the axial plane in a standing position. METHODS: There were 82 eligible patients enrolled in current study, who underwent EOS imaging evaluation before and immediately after bracing. The clinical demographic data (age, gender, Risser sign and menstrual status) were recorded. The correlation analyses between derotation effects and key parameters (age, pre-brace Cobb angle, thoracic kyphosis, lumbar lordosis, vertebral rotation, pelvis axial rotation and apical vertebral level) were performed. The in-brace derotation effects stratified by gender, Risser sign, apical vertebral level, menarche status, coronal balance and sagittal balance were also analyzed. RESULTS: The rotation of apical vertebra was decreased from 8.8 ± 6.0 degrees before bracing to 3.8 ± 3.3 degrees immediately after bracing (p < 0.001), and the derotation rate was 49.2 ± 38.3%. The derotation degrees in brace was significantly correlated with major curve Cobb angle (r = 0.240, p = 0.030), minor curve Cobb angle (r = 0.256, p = 0.020) and total curve Cobb angle (r = 0.266, p = 0.016). Both the pre-brace apical vertebral rotation and apical vertebral level were significantly correlated with derotation effects in brace (p < 0.001). Patients with thoracic major curve showed worse derotation effects than those with lumbar major curve (p < 0.001). In addition, patients with coronal balance showed better in-brace derotation effects than those with coronal decompensation (p = 0.005). CONCLUSIONS: A satisfactory apical vertebral derotation rate (approximately 50%) could be obtained immediately after bracing in AIS patients. Pre-brace Cobb angle of curve, pre-brace apical vertebral rotation, apical vertebral level and coronal balance exhibited close associations with in-brace derotation effects of apical vertebra.

Effect of thoracolumbosacral braces on running ground reaction force components in male individuals with kyphosis.

BACKGROUND & AIMS: Braces are one of the methods for kyphosis treatment, but they can relocate the center of gravity of the trunk, affecting the ground reaction force (GRF) during running. Therefore, this study aimed to investigate the effects of two types of thoracolumbosacral braces on running GRF components in individuals with kyphosis. MATERIALS & METHODS: Participants were 15 males diagnosed with kyphosis who volunteered in this quasi-experimental study. Each subject performed the barefoot running trials on the force plate with one simple brace, with a sensor brace, and without the brace condition. The ground reaction forces components were calculated in the stance phase. Statistical analysis was done with repeated measures test with a significant level of 0.05. RESULTS: Peak medial ground reaction force when running with a sensor brace was lower than running with a simple brace (p = 0.017). Free moments were similar during three running conditions (p > 0.05). CONCLUSION: Lower maximum medial ground reaction force while using a sensor brace may possibly demonstrate the beneficial effects of a sensor brace in individuals with kyphosis.

To corset or not to corset after lumbar spine fixation surgery?: A prospective randomized clinical trial and literature review.

PURPOSE: Orthosis after lumbar fusion surgery is common. However, the evidence for benefit remains to be determined, especially in tropical areas with heavy workers. To investigate postoperative orthosis and whether it affects pain improvement, quality of life, and fusion rate. METHOD: From May 2021 to May 2022, this single-center prospective randomized clinical trial enrolled 110 patients. We excluded 9 patients, and 101 people were analyzed finally. Corset group, in which participants used a corset for 3 months postoperatively; Non-corset group, in which participants didn't wear any orthosis. ODI and VAS scale were recorded before the surgery: 2 weeks, 1 month, 3 months, half a year, and 1 year postoperatively. The lumbar X-ray was done before the surgery, 6 months postoperatively. All complications in 1 year were recorded. RESULTS: Significant decrease in VAS score in the non-corset group since post-operation day 5 (corset group 3.44 ±â€…1.77, non-corset group 3.36 ±â€…1.75, P = .0093) during admission, and also a decrease in admission duration (corset group 11.08 ±â€…2.39, non-corset group 9.55 ±â€…1.75, P = .0004) were found. There was a significantly better ODI score in the non-corset group since post-operation 1 month, while in the corset group until post-operation 3 months. Both groups had no significant difference in satisfaction, complication rates, and X-ray results, such as fusion, angular rotation, sagittal transition, and slip in the neutral position. CONCLUSION: After the transpedicular screw fixation with posterolateral fusion surgery for degenerative spondylolisthesis, non-orthosis is a safe strategy. It can reduce the admission duration and has the trend for better functional outcomes.

A Randomized Comparison Between Anterior Talofibular Ligament Repair Using Broström Operation with and without an Internal Brace.

The aim of the study was to compare the intermediate-term (>24 months) clinical outcomes between anterior talofibular ligament repair using Broström operation with and without an internal brace. Nineteen patients underwent surgery using an arthroscopic traditional Broström repair with an internal brace technique (IB) and Eighteen patients underwent surgery using an arthroscopic traditional Broström repair without an internal brace technique (TB) . All patients were evaluated clinically using the Foot and Ankle Outcome Score (FAOS) and Foot and Ankle Ability Measure (FAAM). According to FAAM, sports activity scores of TB and IB groups were 83.33 ± 5.66 and 90.63 ± 6.21 at the final follow-up (p = .02). There were no significant differences in preoperative and postoperative stress radiographs between the two groups. Total medical expense was more in the IB group (p < .001). It also has a significant superiority in the terms of FAAM scores at sports activity. However, there was no difference during daily life.

Standardized In-harness Ultrasound Protocol Improves Success Rate of Brace Treatment for Dislocated Hips.

OBJECTIVE: Infant hip dislocations benefit from early detection and treatment for optimal outcomes. Prior studies have identified that there remains wide variability in the success rate of bracing between institutions. Although there are standardized methods to screen infants for hip dysplasia, there are no clear guidelines regarding how to image a child being treated for a hip dislocation with a Pavlik harness. As a result, there is substantial variability in how treatment success or failure is monitored between and within institutions. The goal of our study is to determine whether a standardized in-harness imaging protocol improves outcomes and the likelihood of successful treatment for dislocated hips being treated with the Pavlik harness. METHODS: All patients with hip dislocations and pretreatment ultrasound (US) were included from July 2018 to July 2022. A new institutional US protocol was implemented in July 2020, during which standardized in-harness imaging was obtained for patients with hip dislocations. Patients treated before the implementation of standardized in-harness imaging were categorized as nonstandardized and after implementation as a standardized group. Outcomes were compared between standardized and nonstandardized groups. P <0.05 determined the statistical significance. RESULTS: One hundred twenty-eight hips met the inclusion criteria (n = 97 patients). The mean age at diagnosis was 41.6 ± 23.4 days and was predominantly female (85.6%). There was no significant difference between the patients' demographics and baseline clinical characteristics between the standardized and nonstandardized groups. Pavlik harness success rate was significantly higher in the standardized group (85% vs 60%, P = 0.0024). Twenty-eight hips in the nonstandardized group remained dislocated and were indicated for surgical treatment, whereas only 8 hips remained dislocated in the standardized group and necessitated closed or open reduction. CONCLUSIONS: Standardization of in-harness imaging for patients undergoing treatment for developmental hip dislocations can significantly improve the Pavlik harness success rate. These findings emphasize the importance of obtaining images with the hip in flexion and abduction to prevent inadvertent stress during US evaluation for hips that have not yet stabilized, which may lead to premature cessation of the Pavlik harness. LEVEL OF EVIDENCE: Level III.
