THE BIOMECHANICAL ANALYSIS OF PELVIC OSTEOTOMIES APPLIED FOR DDH TREATMENT IN PEDIATRIC PATIENTS.

Objective: The aim: This article aimed to evaluate biomechanical changes during the most commonly used pelvic osteotomies (Salter, Dega, Pemberton) for DDH treatment in pediatric patients.

Patients And Methods: Materials and methods: Virtual pelvic models of 2- and 6-years old patients were created, material properties were assigned, pelvic osteotomies were simulated and biomechanical changes were evaluated using finite element analysis (FEA).

Results: Results: It was revealed that the patient's age impacts pelvic bones and cartilage density (in younger patients the pelvic elements are more pliable - p<0.

MODIFIED SALTER PELVIC OSTEOTOMY FOR THE DDH TREATMENT.

Objectives: Three pelvic osteotomies (Salter, Dega, Pemberton) are widely used in walking patients under seven years old for DDH treatment. We've proposed a modified Salter Pelvic Osteotomy (SPO), which has the advantages of the abovementioned osteotomies.

Methods: Short- and mid-term results were assessed in 19 patients after the modified SPO application.

FACTORS INFLUENCING THE FORMATION OF THE PROXIMAL FEMUR IN PATIENTS WITH CEREBRAL PALSY.

Objective: The aim: Establishment of the factors influencing the formation of femoral neck-shaft angles and femoral torsions indices among the patients with cerebral palsy.

Patients And Methods: Materials and methods: The total number of patients was 46 persons (84 joints). We have examined patients using our method (patent №137567), obtained the true parameters of the femoral neck-shaft angle and femoral torsion, and conducted a statistical analysis of factors that might influence their formation.

Femoral Head Coverage Assessment in Healthy Children Younger than 6 Years.

Introduction: Developmental dysplasia of the hip (DDH) is one of the commonest hip joint pathologies in children; to treat it properly, hip surgeons should know the normal femoral head (FH) coverage by the acetabulum. This paper aims to assess the femoral head coverage in healthy children younger than 6 years.

Methods: 270 hip joint CT scans were selected, and digital pelvic models were created according to these scans.

Salter pelvic osteotomy for the treatment of Developmental Dysplasia of the Hip: assessment of postoperative results and risk factors.

Background: If non-surgical treatment of Developmental Dysplasia of the Hip (DDH) fails or if DDH is late-detected, surgery is necessary. Salter pelvic osteotomy (SPO) is an effective surgical option for such cases.

Objectives: To study the results after SPO; to evaluate risk factors; to reveal radiological parameters that may correlate with results.

Simulation of pelvic osteotomies applied for DDH treatment in pediatric patients using piglet models.

Background: Developmental dysplasia of the hip (DDH) is a common hip joint pathology seen in the pediatric orthopedist's practice. Pelvic osteotomies are the reliable surgical option for DDH treatment in walking patients, and 3 osteotomies (Salter, Dega and Pemberton) are widely used in patients under 6 years of age. Plastic changes in hinge points occur during iliac fragment movement, after the performed osteotomy.
