Novel Minimally-Invasive Triple Pelvic Osteotomy: JiShuiTan Minimally-Invasive Approach

Effects of different pelvic osteotomies on acetabular morphology in developmental dysplasia of hip in children

Developmental dysplasia of hip seriously affects the health of children, and pelvic osteotomy is an important part of surgical treatment. Improving the shape of the acetabulum, preventing or delaying the progression of osteoarthritis is the ultimate goal of pelvic osteotomies. Re-directional osteotomies, reshaping osteotomies and salvage osteotomies are the three most common types of pelvic osteotomy. The influence of different pelvic osteotomy on acetabular morphology is different, and the acetabular morphology after osteotomy is closely related to the prognosis of the patients. But there lacks comparison of acetabular morphology between different pelvic osteotomies, on the basis of retrospective analysis and measurable imaging indicators, this study predicted the acetabular shape after developmental dysplasia of the hip pelvic osteotomy in order to help clinicians make reasonable and correct decisions and improve the planning and performance of pelvic osteotomy.

Some aspects of the choice of surgical approach for triple pelvic osteotomy in the treatment of hip dysplastic instability in children

Aim - on the basis of clinical and laboratory data, to analyze the degree of muscle injury during triple pelvic osteotomy with various approaches in patients with hip dysplasia Matherials and methods. The study included 70 patients aged 12 to 18 years with dysplasia Crowe I grade treated between 2020 and 2021. All children were divided into two groups - I - 35 patients who underwent triple pelvic osteotomy from an anterolateral approach, group II - 35 patients who underwent triple pelvic osteotomy from two approaches (medial and bikini"). In addition to standard radiometry of hip joints, such indicators as the severity of pain syndrome on the VAS scale were evaluated, as well as biochemical analysis of markers of muscle injury (LDH, CPK, creatinine, AST, C-reactive protein) before surgery and on the 3rd and 7th days after surgery. Results. The intensity of the pain syndrome according to the questionnaire data was more pronounced (p0.05) in patients who underwent surgery from an anterolateral access, and the values of CPK and C-reactive protein significantly (p0.05) exceeded those in patients who underwent triple pelvic osteotomy from two surgical approaches. The data obtained indicate greater surgical aggression against the muscles of the hip joint area during the anterolateral approch for triple pelvic osteotomy. Conslusion. A comparative analysis of the traumaticity of surgical approaches during triple pelvic osteotomy in children with hip dysplasia Crowe I degree, based on the assessment of biochemical indicators of markers of muscle injury and the intensity of pain syndrome in the postoperative period showed that the use of anteriorlateral approach significantly (p0.05) has a greater injury to muscle tissue than the use of two surgical accesses (medial and bikini), as evidenced by significant increases in CPK and CRP in the blood, as well as a more pronounced pain syndrome in the immediate postoperative period.
