Acute hematogenous osteomyelitis in children: Management of pandiaphysitis with extensive bone destruction: A case series of thirteen child.

Introduction: and Importance: Acute hematogenous osteomyelitis (AHO) poses a public health problem in severe forms from the outset or with delayed diagnosis. The aim of this work is to describe the management of pandiaphysitis with extensive bone destruction by the Ilizarov external fixator and antibiotics and to evaluate the results. Methods: This is a retrospective, descriptive, cross-sectional and single-center study. It was performed over a seven-year period. We included children with acute hematogenous osteomyelitis complicated by pandiaphysitis of the long bones with extensive bone necrosis. All patients underwent stabilization with an Ilizarov external fixator and antibiotic therapy adapted to the antibiogram in ten cases. One patient had the induced membrane technique. All the patients underwent dynamization of the Ilizarov external fixator followed by immobilization with a cast or a splint for the lower limb. Outcomes: 13 medical files were collected during the study period. The sex ratio was 1.6, the average age was 7.56 years. Three localization sites: humerus for 3 cases, femur for 3 cases and tibia for 7 cases. The germ has been identified in ten cases. Methicillin-resistant staphylococcus aureus was the most common. Bone consolidation is obtained in all cases with an average delay of ten months. Conclusion: The Ilizarov external fixator associated with antibiotics has proven its effectiveness in the management of pandiaphysitis with extensive bone destruction. This method is an alternative in the therapeutic arsenal available to pediatric orthopedic surgeons. Level of evidence: IV, Case series.

Calcaneal lengthening osteotomy in the management of idiopathic flatfoot in children: cCase series of twenty-one feet.

INTRODUCTION: Flatfoot is a frequent reason for consultation in pediatric orthopedics. The calcaneal lengthening osteotomy according to the EVANS technique is a therapeutic alternative. The objective of this work was to evaluate the short and medium term clinical and radiological results of calcaneal lengthening osteotomy in children with idiopathic flat foot valgus. METHODS: This study concerned 12 children and 15 ft treated surgically by calcaneal lengthening osteotomy by an orthopedic surgeon in a pediatric orthopedic surgery center. The evaluation of the results was clinical according AOFAS score and radiological. RESULTS: The deformity was reducible in all of our patients. The mean preoperative AOFAS score was 61, postoperatively 90. The overall result was excellent in 11 cases (11 ft) and good in 4 cases. The postoperative radiological result was close to normal values. CONCLUSION: Calcaneal lengthening osteotomy is a reliable and recommended technique for the correction of symptomatic idiopathic flatfoot. LEVEL OF EVIDENCE: IV, Case series.

The "Patient management problem" as a formative evaluation during the internship.

INTRODUCTION: The evaluation of the internship in pediatric orthopedics is based on a clinical examination in the form of ECOS, after the internship period involving all surgical specialties. The validation of the clinical examination test does not necessarily mean that the student has achieved his internship objectives and vice versa. This discrepancy between the evaluation test and the field of the internship prompted us to question the need to establish a formative evaluation method during the clinical internship. METHODS: Our study is a prospective, evaluative, longitudinal study, from October 2019 until September 2020, in the infantile orthopedics and traumatology department of the "Béchir HAMZA" children's hospital in Tunis. We carried out a formative evaluation using the "Patient Management Problem" (PMP), with two different subjects, one on acute hematogenous osteomyelitis, the other on malignant bone tumors, with a Pre-test and a Post-test for each PMP. RESULTS: We had 18 interns, during the period between October 2019 and September 2020, including 13 who had medical training in Tunisian faculties. The score for the acute osteomyelitis pretest was 14.56 on average, the PMP score was 16.33 on average, with one interne scoring zero. The posttest mean was 18.11 [13.75-20], with a statistically significant difference from the pretest. The pre-test for the bone tumors' PMP had an average of 9.7 [3.75-15], that of PMP was 12.6 [0-20]. There was an improvement in post test scores with an average of 16.45. Comparing the two tests we noticed that the scores for the PMP osteomyelitis were higher than the scores for the PMP bone tumors with a significant difference between the two groups (p = 0.04). CONCLUSIONS: The results of this pilot project are encouraging for the establishment of a continuous evaluation by the PMP method, intended for interne during the pediatric orthopedic surgery internship. This method allows learning and formative evaluation of learners by evaluating clinical and therapeutic reasoning.
