What Are the Psychosocial Effects of Pavlik Harness Treatment? A Prospective Study on Perceived Impact on Families and Maternal-Infant Bonding.

BACKGROUND: The Pavlik harness (PH) is the most common treatment for infants with developmental dysplasia of the hip. Although success rates are high when used appropriately, brace treatment may impact family function and parental bonding. The purpose of this study was to prospectively determine how PH treatment affected these psychosocial variables. METHODS: This is a prospective, single-surgeon study at a tertiary-care, urban, academic children's hospital between November 2022 and March 2023. All patients newly treated with a Pavlik were eligible. Caregivers were administered the Postpartum Bonding Questionnaire and the Revised Impact on Family Scale (rIOFS) at the baseline visit and 2- and 6 weeks following treatment initiation. Demographic and treatment-specific information was collected through surveys and retrospective chart review. Descriptive statistics and bivariate analysis were used. RESULTS: A total of 55 caregiver-child dyads were included in the final analysis. Most patients were female (89%) and/or first-born (73%). Forty (73%) hips were diagnosed as having stable dysplasia. rIOFS scores steadily improved from baseline, through 2- and 6 weeks posttreatment initiation. Six-week rIOFS scores were significantly lower than both baseline ( P= 0.002) and 2 weeks ( P =0.018). Average parental bonding scores also improved steadily throughout treatment and did not surpass the threshold of clinical concern at any time. Neither full-time harness use (24 h/d vs. 23 h/d based upon clinical stability) nor age at treatment initiation had a statistically significant effect on parental bonding or family functioning (all P >0.05). Additional demographic variables such as birth order, parental history of anxiety/depression, and relative socioeconomic disadvantage also had no significant effect on psychosocial outcomes. CONCLUSION: PH treatment did not significantly impact maternal-fetal bonding or family dynamics. Relative to other pediatric diseases, PH treatment has an impact on family life greater than that of single-leg spica, but less than that of school-age children with chronic medical illnesses. As PH treatment is a widely used treatment for infantile developmental dysplasia of the hip, this study provides information that clinicians may use to more accurately counsel families and assuage parental concerns. LEVELS OF EVIDENCE: Level IV-prospective uncontrolled cohort study.

New Classification for Pediatric Proximal Fifth Metatarsal Fractures.

Proximal fifth metatarsal fractures are the most common foot fractures in children. Attempts to classify these injuries are misapplied and inadequately predict outcomes. This is the first study to identify factors associated with healing in pediatric fifth metatarsal fractures. In this retrospective cohort study (N = 305), proximal fifth metatarsal fractures were classified on radiographs by location on the bone, alignment (transverse or oblique), displacement (>2 mm), and completion through the bone. Based on the literature, they were secondarily sorted by category: apophyseal, intra-articular metaphyseal, extra-articular metaphyseal, and diaphyseal. Primary outcomes included times to healing, indicated by clinical symptoms, immobilization, and return to sports, as well as radiographic callus formation, bridging, and remodeling. Healing times were compared by ANOVA and linear regression. Location had a significant effect on times of immobilization and return to sports, but alignment, displacement, and completion were not associated with healing. When re-classified, the categories were also associated with immobilization and return to sports. Apophyseal fractures healed fastest and diaphyseal fractures required the most time to heal. There was no difference between extra- and intra-articular fractures. For every year of age, symptoms resolved about 2 days sooner. Neither gender nor body mass index (BMI) was positively or negatively associated with healing times. In conclusion, classifying fractures by apophyseal, metaphyseal, and diaphyseal is the most concise, accurate, and useful system. This is the largest series of nonoperatively treated proximal fifth metatarsal fractures in children and a robust standard to which surgical management can be compared.

Socioeconomic Deprivation and its Associations With Follow-up Compliance After In Situ Pinning of Slipped Capital Femoral Epiphysis.

BACKGROUND: Slipped capital femoral epiphysis (SCFE) is a common cause of hip pain in adolescents and is most often treated by in situ screw fixation. Orthopaedic follow-up is critical after treatment for SCFE due to risks of complications and subsequent contralateral slip. Recent studies have shown that socioeconomic deprivation is associated with decreased fracture care compliance, but no studies have explored this relationship with SCFEs. The study aims to determine the relationship between socioeconomic deprivation and SCFE follow-up care compliance. METHODS: This study included pediatric patients treated with in situ pinning of SCFE between 2011 and 2019 at a single tertiary-care urban children's hospital. Demographic and clinical information were obtained from electronic medical records. The Area Deprivation Index (ADI) was used to quantify the socioeconomic deprivation of each. Outcome variables included patient age and status of physeal closure at the most recent appointment, in addition to the length of follow-up (mo). Statistical relationships were evaluated using nonparametric bivariate analysis and correlation. RESULTS: We identified 247 evaluable patients; 57.1% were male, and the median age was 12.4 years. Most slips were stable (95.1%) and treated with isolated unilateral pinning (55.9%). Median length of follow-up was 11.9 months (interquartile range, 4.95 to 23.1) with median patient age at final visit of 13.6 years (interquartile range, 12.4 to 15.1). Only 37.2% of patients were followed until physeal closure. The mean ADI spread in this sample was similar to the national distribution. However, patients in the most deprived quartile were lost to follow-up significantly earlier (median, 6.5 mo) than those in the least deprived quartile (median, 12.5 mo; P <0.001). Throughout the entire cohort, there was a significant, inverse relationship between deprivation and follow-up length ( rs (238) = -0.3; P <0.001), with this relationship most pronounced in the most deprived quartile. CONCLUSIONS: In this sample, ADI spread was representative of national trends, and the incidence of SCFE was distributed evenly across deprivation quartiles. However, follow-up length does not mirror this relationship; increased socioeconomic deprivation is associated with an earlier loss to follow-up (often well before physeal closure). LEVEL OF EVIDENCE: Level II-retrospective prognostic study.
