Purpose This clinical trial compares the functional and radiological outcomes of single-bone fixation to both-bone fixation of unstable paediatric both-bone forearm fractures. Methods This individually randomized two-group parallel clinical trial was performed following the Consolidated Standards of Reporting Trials (CONSORT) statement at a single academic tertiary medical centre with an established paediatric orthopaedics unit. All children aged between nine and 15 years who presented to the emergency department at Assiut university with unstable diaphyseal, both-bone forearm fractures requiring surgical intervention between November 1, 2018, and February 28, 2020, were screened for eligibility against the inclusion and exclusion criteria. Inclusion criteria were diaphyseal unstable fractures defined as shaft fractures between the distal and proximal metaphyses with an angulation of > 10°, and/or malrotation of > 30°, and/or displacement > 10 mm after attempted closed reduction. Exclusion criteria included open fractures, Galeazzi fractures, Monteggia fractures, radial head fractures, and associated neurovascular injuries. Patients who met the inclusion criteria were randomized to either the single-bone fixation group (intervention) or the both-bone fixation group (control). Primary outcomes were forearm range of motion and fracture union, while secondary outcomes were forearm function (price criteria), radius re-angulation, wrist and elbow range of motion, and surgical time Results A total of 50 children were included. Out of these 50 children, 25 were randomized to either arm of the study. All children in either group received the treatment assigned by randomization. Fifty (100%) children were available for final follow-up at six months post-operatively. The mean age of single-bone and both-bone fixation groups was 11.48 ± 1.93 and 13 ± 1.75 years, respectively, with a statistically significant difference (p = 0.006). There were no statistically significant differences in gender, laterality, affection of the dominant hand, or mode of trauma between single-bone and both-bone fixation groups. All patients in both groups achieved fracture union. There mean radius re-angulation of the single-bone fixation groups was 5.36 ± 4.39 (0–20) degrees, while there was no radius re-angulation in the both-bone fixation group, with a statistically significant difference (p < 0.001). The time to union in the single-bone group was 6.28 ± 1.51 weeks, while the time to union in the both-bone fixation group was 6.64 ± 1.75 weeks, with no statistically significant difference (p = 0.44). There were no infections or refractures in either group. In the single-bone fixation group, 24 (96%) patients have regained their full forearm ROM (loss of ROM < 15°), while only one (4%) patient lost between 15 and 30° of ROM. In the both-bone fixation group, 23 (92%) patients have regained their full forearm ROM (loss of ROM < 15°), while only two (8%) patients lost between 15 and 30° of ROM. There was no statistically significant difference between groups in loss of forearm ROM (p = 0.55). All patients in both groups regained full ROM of their elbow and wrist joints. On price grading, 24 (96%) and 23 (92%) patients who underwent single bone fixation and both-bone fixation scored excellent, respectively. Only one (4%) patient in the single-bone fixation group and two (8%) patients in the both-bone fixation group scored good, with no statistically significant difference in price score between groups (p = 0.49). The majority of the patients from both groups had no pain on the numerical pain scale; 22 (88%) patients in the single-bone fixation group and 21 (84%) patients in the both-bone fixation groups, with no statistically significant difference between groups (p = 0.38). The single-bone fixation group had a significantly shorter mean operative time in comparison to both-bones plating (43.60 ± 6.21 vs. 88.60 ± 10.56 (min); p < 0.001). Conclusion Single-bone ulna open reduction and plate fixation and casting are safe and had a significantly shorter operative time than both-bone fixation. However, single-bone ORIF had a higher risk radius re-angulation, alas clinically acceptable. Both groups had equally excellent functional outcomes, forearm ROM, and union rates with no complications or refractures. Long-term studies are required.

Introduction: Pelvic sarcomas may present with vague symptoms. The aim of this study was to examine the characteristics and clinical presentations of different types of pelvic sarcoma in children.Methods: This is a retrospective cohort study of patients up to 21 years of age with the diagnosis of pelvic sarcoma between January 2000 and June 2013. Data on demographics, tumor type and location, and clinical presentation were collected from the medical records.Results: A total of 59 patients [37 males (62.7%) and 22 females (37.3%)] were examined in this study. Mean age at presentation was 11.3 ± 5 years (range 0.8–21 years). Thirty-six patients had Ewing sarcoma (61%), 9 osteosarcoma (6.8%), 4 undifferentiated sarcoma (6.8%), 2 (3.4%) rhabdomyosarcoma, 2 synovial cell sarcoma, and one (1.7%) of each fibrosarcoma, dermatofibrosarcoma, fibromyxoid sarcoma, chondrosarcoma, chordoma, and epithelioid sarcoma. Pain at presentation was reported in 41 patients, 13 mass, 8 limping, and 5 neurologic symptoms. Most of the bony tumors were painful (77%), while most of the soft tissue tumors were painless (70%). Nine patients presented with constitutional symptoms. Most patients presented within 4–12 months from symptoms beginning. Twenty-one patients (35.6%) presented with metastases (14 Ewing sarcoma, 6 osteosarcoma, and 1 synovial cell sarcoma). Pelvic radiographs showed lytic lesion in 11 patients, 4 sclerotic lesions, 6 mixed lesion, 6 had only soft tissue mass, 1 radiograph showed osteopenia, and 2 radiographs were reported normal.Conclusion: Ewing sarcoma was the most common pelvic sarcoma tumor in children. In most cases, pelvic sarcoma in children presented with pain mimicking other benign conditions. Some patients presented with metastatic disease with no prognostic clinical or radiographical signs or symptoms. Pelvic sarcoma should be considered a differential diagnosis as part of children work up.

Objectives The primary objective was to compare refracture incidence of both radius and ulna fracture in two groups treated using intramedullary k-wires where the wires were buried in group I and left exposed in group II. The secondary objective was to compare the final functional outcomes and complications incidence. Methods Between March 2019 and February 2021, 60 pediatric patients presented with unstable radius and ulna fractures amenable to surgical intervention using intramedullary K-wires were randomized into Group I (k-wires were buried under the skin) or group II (k-wires were exposed above the skin by 2 cm). In group I, k-wires were removed after full union under general anesthesia as a day case procedure; in group II they were removed in the outpatient clinic. Functional outcome per Price criteria was reported at one-year follow-up. Results Included patients had a mean age of 7.6 years (range 5 to 10). The mean operative time was significantly higher in group I (32.33 ± 7.51 vs. 36.77 ± 8.70 minutes, P = 0.03), no difference regarding intraoperative x-ray exposure (43.12 ± 15.52 vs. 41.6 ± 11.96 seconds, P = 0.67). Fracture union was achieved after a mean of 44 ± 2.6 days in group I and 43 ± 1.87 days in group II. One patient had refracture, and two had deep infection necessitated surgical debridement in group I. All patients reported excellent scores per Price criteria and achieved full wrist and elbow ROM compared to the contralateral non-injured side. Conclusion Exposed implants are a safe option when dealing with pediatric forearm fractures with similar complications rate and functional outcomes compared to buried implants; however, it confers fewer hospital admissions.

In our series, the addition of posterior capsulotomy to Achilles tenotomy did not improve the mean dorsiflexion at latest follow up or decrease the rate of recurrence of equinus deformity in both idiopathic and non-idiopathic clubfeet. It is therefore advisable that percutaneous Achilles tenotomy alone be used in the correction of equinus deformity in both idiopathic and non-idiopathic congenital talipes equinovarus after successful Ponseti serial casting.
