Musculoskeletal injections for palliative treatment of neuromuscular hip dysplasia patients: how I do it.

This review describes our institution's standardized technique as well as potential pitfalls for therapeutic steroid injections in children with symptomatic neuromuscular hip dysplasia. Symptomatic, painful neuromuscular hip dysplasia can dramatically affect quality of life. Steroid injections are used to identify the source of perceived pain, temporarily treat pain while awaiting surgical intervention, or for therapeutic management for nonoperative hip joints.

Clinical impact of diagnostic image-guided injections for musculoskeletal pain work-up in adolescent and adult patients at a children's hospital: initial results.

OBJECTIVE: To assess the clinical impact of diagnostic musculoskeletal (MSK) injections on treatment decision-making in adolescent and adult patients at a children's hospital. MATERIALS AND METHODS: Retrospective study in patients who underwent diagnostic MSK injections by fluoroscopy or ultrasound (US) between 8/2020 and 3/2023 at a children's hospital. Patients received ropivacaine and triamcinolone acetonide at pain site, reporting quantitative FACES pain score prior to, immediately following, and 2-3 days following injection. Impact on patient care was subsequently assessed. RESULTS: A total of 109 diagnostic fluoroscopic or US MSK injection referrals (mean: 17.6 years old) were included, most commonly hip (76.2%), ankle (9.2%), and iliopsoas tendon sheath (8.3%). Pain improvement occurred in 89.0% immediately and 67.9% 2-3 days after MSK injection, with net 84.4% exhibiting improvement based on pain scores and clinical exams. When there was pain improvement at the site of injection, there was a statistically higher incidence of operative intervention or additional therapeutic injections compared with the cohort that did not have symptom improvement (88% versus 35.3%, P < 0.0001). For the 15.6% (N = 17) of referrals that did not have pain improvement, 17.6% (n = 3) ultimately had an operative intervention at a separate site from the diagnostic injection, as an alternative etiology for the pain was found. CONCLUSION: Image-guided MSK injections play an important role in the management of musculoskeletal disorders. 84.4% of referrals experienced symptom relief, improving confidence for treatment decision-making. Importantly, 15.6% of patients were found to have an alternative etiology for symptoms, altering management altogether.

Ipsilateral Supracondylar and Medial Epicondyle Humerus Fractures in Pediatric Patients: A Retrospective Analysis of Incidence, Epidemiology, Treatment, and Outcomes.

BACKGROUND: Pediatric supracondylar humerus (SCH; AO/OTA13-M/3.1) and medial epicondyle fractures (AO/OTA13u-M/7.1) are common. Concomitant SCH with ipsilateral medial epicondyle fractures remain scarcely reported. We investigated the epidemiology, treatment, and outcomes of this rare, combined injury. METHODS: A retrospective review of pediatric patients with concomitant SCH and medial epicondyle fractures at a level 1 hospital from 2010 to 2020 was performed. Patient data, treatments, and outcomes were assessed. Radiographs were reviewed for fracture classification and alignment. Patients aged above 18 years and those with inaccessible imaging were excluded. Descriptive statistics were performed. RESULTS: Of 3344 patients undergoing surgery for SCH fractures, 14 (6 females, mean: 10.59 y) with concomitant SCH and medial epicondyle fractures were included. Overall, 28.6% of patients exhibited preoperative nerve palsies (3 PIN, 1 median nerve). There was 1 flexion type and 13 Gartland type III SCH fractures. Medial epicondyle fracture displacement averaged 4.13 mm (range: 2 to 7 mm). Thirteen medial epicondyle fractures occurred medial to the physis with 1 through the physis. Eight patients (57.1%) had medial fixation-7 medial pins, 1 medial screw-which captured both the medial epicondyle and medial column of the SCH fracture. Six medial epicondyles were treated closed. The average time to pin pull was 33.1 days (range: 27 to 51 d) with average follow-up of 138.6 days (range: 27 to 574 d). Overall, 50% of patients completed physical therapy (PT). Complications occurred in 4 cases: prominence of a medial pin, 1 patient required additional PT and dynamic splinting for loss of functional extension, 1 patient underwent a manipulation under anesthesia 3.5 months postoperatively for flexion contracture, and 1 patient developed medial epicondyle nonunion and SCH malunion that underwent corrective osteotomy 10.5 months postoperatively. CONCLUSIONS: Concurrent SCH and medial epicondyle fractures exhibited a high rate of nerve palsy (28.6%) and complications (28.6%) and were frequently referred to physical therapy. While patients treated without medial fixation went on to union, this combined injury might represent a relative indication for medial pinning of the SCH fracture. Further studies on this rare injury pattern are needed to determine optimal treatment methods. LEVEL OF EVIDENCE: Level IV-therapeutic.

Evaluating Chat Generative Pre-trained Transformer Responses to Common Pediatric In-toeing Questions.

OBJECTIVE: Chat generative pre-trained transformer (ChatGPT) has garnered attention in health care for its potential to reshape patient interactions. As patients increasingly rely on artificial intelligence platforms, concerns about information accuracy arise. In-toeing, a common lower extremity variation, often leads to pediatric orthopaedic referrals despite observation being the primary treatment. Our study aims to assess ChatGPT's responses to pediatric in-toeing questions, contributing to discussions on health care innovation and technology in patient education. METHODS: We compiled a list of 34 common in-toeing questions from the "Frequently Asked Questions" sections of 9 health care-affiliated websites, identifying 25 as the most encountered. On January 17, 2024, we queried ChatGPT 3.5 in separate sessions and recorded the responses. These 25 questions were posed again on January 21, 2024, to assess its reproducibility. Two pediatric orthopaedic surgeons evaluated responses using a scale of "excellent (no clarification)" to "unsatisfactory (substantial clarification)." Average ratings were used when evaluators' grades were within one level of each other. In discordant cases, the senior author provided a decisive rating. RESULTS: We found 46% of ChatGPT responses were "excellent" and 44% "satisfactory (minimal clarification)." In addition, 8% of cases were "satisfactory (moderate clarification)" and 2% were "unsatisfactory." Questions had appropriate readability, with an average Flesch-Kincaid Grade Level of 4.9 (±2.1). However, ChatGPT's responses were at a collegiate level, averaging 12.7 (±1.4). No significant differences in ratings were observed between question topics. Furthermore, ChatGPT exhibited moderate consistency after repeated queries, evidenced by a Spearman rho coefficient of 0.55 ( P = 0.005). The chatbot appropriately described in-toeing as normal or spontaneously resolving in 62% of responses and consistently recommended evaluation by a health care provider in 100%. CONCLUSION: The chatbot presented a serviceable, though not perfect, representation of the diagnosis and management of pediatric in-toeing while demonstrating a moderate level of reproducibility in its responses. ChatGPT's utility could be enhanced by improving readability and consistency and incorporating evidence-based guidelines. LEVEL OF EVIDENCE: Level IV-diagnostic.

How Reliable Is the Measurement of the Lateral Center Edge Angle on Scoliosis Radiographs for Detecting Acetabular Dysplasia?

PURPOSE: Hip dysplasia reportedly occurs in up to 12% of the general population and may be higher in patients with adolescent idiopathic scoliosis (AIS). When using lateral center edge angle (LCEA) measurements to help identify hip dysplasia, it is uncertain if this measurement can be performed reliably on scoliosis radiographs due to parallax. The purpose of this study is to evaluate the reliability of measuring LCEA on scoliosis radiographs compared with standard pelvis radiographs. METHODS: This study evaluated 40 hips on 20 patients (mean age 12.5 years ± 3.1; 50% Female) who received PA scoliosis radiographs and AP pelvis radiographs within 1 year of each other. Review was performed by 4 pediatric radiologists (2 general, 2 MSK), 2 pediatric orthopaedic surgeons, and 1 research fellow. Radiographic measurement of the LCEA for each hip was first performed on the scoliosis radiograph. After a minimum of 3 days, the LCEA was measured on a pelvis radiograph of the same individual obtained within 1 year of the scoliosis radiograph. Pearson coefficient was used to measure agreement between scoliosis and pelvis radiograph measurements. Intraclass correlation coefficient (ICC) was used to evaluate intraobserver and interobserver agreement. ICC values <0.5 were classified as poor reliability, 0.5 to 0.75 were classified moderate, 0.75 to 0.90 were classified good, and >0.9 indicated excellent reliability. RESULTS: The mean difference between scoliosis and pelvis radiographs was 54 ± 79 days. There was good-to-excellent interobserver agreement on LCEA measurements made between readers on scoliosis radiographs (ICC: 0.94, 95% CI: 0.90-0.96, P <0.001) and pelvis radiographs (ICC: 0.91, 95% CI: 0.83-0.95, P <0.001), and moderate-to-excellent intraobserver agreement for scoliosis radiographs (ICC range: 0.68 to 0.98; P <0.001) and pelvis radiographs (ICC range: 0.62 to 0.96; P <0.001). There was a strong correlation between LCEA measurements made on scoliosis and pelvis radiographs ( r2 =0.66, P <0.001), and the intermodality agreement between scoliosis and pelvis radiograph LCEA measurements were moderate to good (ICC range: 0.68 to 0.89, P <0.001). CONCLUSIONS: Overall, there was good-to-excellent agreement between readers on scoliosis and pelvis radiographs, respectively, and moderate-to-excellent intraobserver agreement between LCEA measurements made on scoliosis radiographs and pelvis radiographs, respectively. LCEA measurements made on scoliosis radiographs strongly correlated to the measurements made on pelvis radiographs, and the intermodality ICC was also considered moderate to good. Dedicated pelvis radiographs may not be necessary during scoliosis workup and follow-up surveillance, thereby decreasing radiation exposure, cost, and improving patient care workflow. LEVEL OF EVIDENCE: Level IV-diagnostic study.
