Article entitled ¿combination prostheses and integral prostheses for the rehabilitation of crowe iii - w developmental myelial dysplasia initial stability "written by li yang, lu hui, huang deng hua, zou longfei, zhang zhongjie, tan meiyun, published by china organization engineering research on 12/14/2021 was reviewed.To explore the advantages and disadvantages of low femoral and neck bone amputee combined with a one-piece prosthesis or a combination prosthesis for the treatment of crowe i-iv developmental hip joint dysplasia.Retrospective analysis of clinical data of 36 patients with crowe itv developmental hip dysplasia admitted to the hospital of september 2015 to august 2019 southwest medical university, 5 male, 31 female, aged 27-64, 19 left-hand side.In the 17 cases on the right, all were treated for total hip replacement.In 18 cases, the integrated wagner cone was used after the lower femoral neck section and in 18 cases the combined s-rom prosthesis was used after the lower femoral neck section.Finding and conclusions: srom femoral i degree stress occlusion (stress fracture) effect 15 cases, ii degree, srom group there was one case of femoral paralysis of 6.7 cm of the limb.There was 1 post-operative development of peroneal thrombosis.Depuy synthes srom modular hip system was used as well as competitor products.In the case of s-rom prostheses, they were fitted with 12 pinnacle hip prostheses.6 cases of gripton-coated hip prostheses, 13 cases of ceramics, 5 cases of ceramics high cross-linked polyethylene.In terms of complications, no dislocation, aseptic loosening and infection around the prosthetic were observed and no significant stress-masking effect was observed at the proximal end of the femur.It is worth mentioning that in the case of s-rom group 2 patients, the initial stability of the posterior prox sleeve was slightly worse, the stability was significantly increased when the sleeve was placed 180° according to the proximal medullary cavity shape.There were no medical interventions/revisions/invasive treatments noted.
