RESUMO
BACKGROUND: Surgical treatment options of discoid lateral meniscus in pediatric patients consist of saucerization with or without meniscal repair, meniscocapular stabilization, and, less often, subtotal meniscectomy. PURPOSE: To describe a large, prospectively collected multicenter cohort of discoid menisci undergoing surgical intervention, and further investigate corresponding treatment of discoid menisci. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A multicenter quality improvement registry (16 institutions, 26 surgeons), Sports Cohort Outcomes Registry, was queried. Patient characteristics, discoid type, presence and type of intrasubstance meniscal tear, peripheral rim instability, repair technique, and partial meniscectomy/debridement beyond saucerization were reviewed. Discoid meniscus characteristics were compared between age groups (<14 and >14 years old), based on receiver operating characteristic curve, and discoid morphology (complete and incomplete). RESULTS: In total, 274 patients were identified (mean age, 12.4 years; range, 3-18 years), of whom 55.6% had complete discoid. Meniscal repairs were performed in 55.1% of patients. Overall, 48.5% of patients had rim instability and 36.8% had >1 location of peripheral rim instability. Of the patients, 21.5% underwent meniscal debridement beyond saucerization, with 8.4% undergoing a subtotal meniscectomy. Patients <14 years of age were more likely to have a complete discoid meniscus (P < .001), peripheral rim instability (P = .005), and longitudinal tears (P = .015) and require a meniscal repair (P < .001). Patients ≥14 years of age were more likely to have a radial/oblique tear (P = .015) and require additional debridement beyond the physiologic rim (P = .003). Overall, 70% of patients <14 years of age were found to have a complete discoid meniscus necessitating saucerization, and >50% in this young age group required peripheral stabilization/repair. CONCLUSION: To preserve physiological "normal" meniscus, a repair may be indicated in >50% of patients <14 years of age but occurred in <50% of those >14 years. Additional resection beyond the physiological rim may be needed in 15% of younger patients and 30% of those aged >14 years.

BACKGROUND: Collagen VI-related myopathies with pathologic COL6A1, COL6A2, and COL6A3 variants manifest as a phenotypic continuum of rare disorders, including Bethlem myopathy (BM), characterized by early onset muscle weakness, proximal joint contractures, and distal joint laxity. Herein we discuss the concomitant orthopedic manifestations of BM, potential management strategies, and patient outcomes. METHODS: An IRB-approved retrospective cohort study (n=23) from 2 pediatric institutions with a confirmed diagnosis of BM. Charts were reviewed for demographic data, age of disease presentation and diagnosis, COL6 genotype, diagnosis method, ambulation status, need for assistance, musculoskeletal abnormalities, other systemic comorbidities, advanced imaging and screening diagnostics, previous surgical interventions, and progression of the disease. RESULTS: The mean age was 11.65 years (range 3 to 19 y). Mean age at initial presentation with symptoms was 4.18 years old, whereas diagnosis was delayed until 8.22 years old on average. Muscle weakness was the most common presenting symptom (65.2%), and 73.9% of patients required some use of assistive or mobility devices. Overall, 30.4% of patients were diagnosed with scoliosis; 57.1% required operative intervention for their scoliosis; 43.5% of patients had acetabular dysplasia; 10% required open reduction of a dislocated hip; 10% required closed reduction with hip spica application; 10% required bilateral periacetabular osteotomies for instability; 91.3% of patients developed foot and ankle deformities; 33.3% of patients underwent posteromedial-lateral equinovarus releases; 28.6% required an Achilles tendon lengthening, and 86.9% of patients had muscle tendon contractures, the most common locations being the ankle (55%) and elbow (40%). CONCLUSION: Although often less severe than other more common neuropathies and myopathies like Charcot-Marie-Tooth disease and Duchenne muscular dystrophy, BM does lead to progressive musculoskeletal deformity and disability. Its relative rarity makes it less familiar to providers and likely contributes to delays in diagnosis. Scoliosis, hip dysplasia, and equinus and varus ankle deformities are the most common musculoskeletal deformities. Physicians and surgeons should appropriately counsel patients and families about the clinical course of this disorder and the potential need for mobility assistance or surgical procedures. LEVEL OF EVIDENCE: III, Prognostic. study.

The purposeof this study was to compare outcomes of operatively treated pediatric distal third tibial shaft fractures fixed with elastic nailing or plate fixation and to evaluate the incidence of concurrent distal tibia physeal fractures. Retrospective review identified skeletally immature patients that underwent operative fixation of distal third tibia fractures at a level 1 children's hospital from 2010 to 2020. Patient and fracture characteristics were recorded. Analysis of treatment outcomes was performed and rates of concurrent distal tibia physeal fractures were evaluated. Of the 214 surgically treated tibial shaft fractures, 43 were distal third fractures. A concurrent distal tibia physeal fracture was present in 32.6% of patients. These were significantly associated with spiral distal third tibial shaft fractures. The presence of concurrent physeal fractures did not affect patient treatment outcomes. Comparing elastic nailing versus open reduction and plating revealed no difference with time to fracture union, time of postoperative immobilization, or time to full weight-bearing. While elastic nailing was associated with increased coronal angulation, translation, and shortening of fractures on initial postoperative imaging, there was no difference in rates of malunion at final follow-up. In our series, there were no differences in treatment outcomes based on fixation method. Our operatively treated distal third tibial shaft fractures had a higher rate of associated distal tibial physeal fractures than previously published in the pediatric orthopedic literature. We recommend careful evaluation of the ankle for concurrent physeal injuries in patients with distal third tibial shaft fractures indicated for operative treatment. Level of evidence: level III therapeutic study - retrospective comparative study.

Surgical treatment of radial tears in the junction of the anterior horn and body of the lateral meniscus is indicated in the acute setting and with failure of nonoperative therapy. There are several options for arthroscopic repair; however, these are more technically difficult to perform because of the current surgical instruments available to address these tears. An outside-in technique is the current standard of care for this tear location and pattern. We present a technique for an all-inside side-to-side repair of the lateral meniscus for radial tears in the junction of the anterior horn and body.
RESUMO
BACKGROUND: Injuries of the tarsometatarsal joint complex ranging from purely ligamentous to multidirectionally unstable midfoot fracture-dislocations are anatomically fixed to minimize long-term sequelae including post-traumatic arthritis, pes planus deformity, and chronic pain. Lateral column disruption is commonly treated with temporary Kirschner wire (K-wire) fixation, maintaining alignment during healing and allowing resumption of physiologic motion after hardware removal. More unstable fracture patterns may require temporary cortical screw fixation to maintain adequate reduction. We evaluated the efficacy of temporary lateral column screw fixation compared to K-wire fixation for Lisfranc fracture-dislocation treatment. METHODS: This retrospective cohort study reviewed 45 patients over fourteen years who underwent Lisfranc fracture-dislocation fixation at a level-one trauma center. All patients underwent medial and middle column fixation; 31 underwent lateral column fixation. Twenty six patients remained after excluding those without electronic records or follow-up. The primary outcome was radiographic lateral column healing before and after hardware removal; secondary outcomes included pain, ambulation, and return to normal shoe wear. RESULTS: Twenty patients were male, with mean age 41 years. Thirteen patients underwent cortical screw fixation and twelve K-wire fixation. One had both implants. Twenty four patients underwent lateral column hardware removal; all had radiographic evidence of bony healing before hardware removal. Mean follow-up was 88.2 ± 114 weeks for all patients. The cortical screw cohort had significantly longer mean time to hardware removal (p = 0.002). The K-wire cohort had significantly more disuse osteopenia (p = 0.045) and postoperative pain (p = 0.019). CONCLUSIONS: Radiographic and clinical outcomes of unstable Lisfranc fracture-dislocation treatment support temporary lateral column screw fixation as an alternate technique. LEVEL OF CLINICAL EVIDENCE: 3 (retrospective cohort study).

The objective of this study was to understand postoperative resorption of the anterior osseous fragment following closed reduction and percutaneous pinning (CRPP) of pediatric supracondylar humerus fractures and its effect on final range of motion (ROM). Eighty-six patients that underwent CRPP had sagittal and or axial plane deformities resulting in an anterior fragment. Humerocapitellar angle (HCA), anterior humeral line (AHL) and angle of rotation (AoR) were measured. A total of 11 (12.8%) patients failed to resorb the anterior fragment, 10 (90.9%) had satisfactory ROM. HCA initially was acceptable in 40 (46.5%) patients, and 37 (92.5%) demonstrated acceptable ROM. Final HCA was acceptable in 44 (51.2%) patients and 42 (95.4%) had acceptable final ROM. AHL was in the anterior third of the capitellum in 35 (40.6%) patients and 33 (94.3%) had acceptable ROM. Final AHL was in the anterior third of the capitellum in 43 (50.0%) patients and 41 (95.3%) had acceptable final ROM. No difference was found between acceptable ROM and HCA or AHL at either follow-up. Sixty-five and 21 patients had an AoR of 0° and between 23 and 36°, respectively. A total of 59 (90.7%) patients with an AoR of 0°, and 18 (85.7%) patients with an AoR of 23-36° displayed acceptable ROM. A total of 57 (87.7%) patients with an AoR of 0° and 18 (85.7%) with an AoR of 23-36° resorbed the anterior fragment. No association was found between rotational deformity and postoperative ROM or fragment resorption. Postoperative sagittal and axial plane alignment, HCA, AHL, AoR and resorption of the anterior osseous fragment does not correlate with final ROM.
