TOPS for individuals with limb amputation using osseointegration implants (OI) has proven to consistently and significantly improve quality of life and mobility for the vast majority of amputees, previously using a socket prosthesis also experiencing socket-related problems. As with any implant, complications such as infection, aseptic loosening, or implant fracture can occur, which may necessitate hardware removal. Approximately half of patients who undergo a below-knee amputation are able to utilize an artificial leg acceptably well with a socket-suspended prosthesis. However, the other half of patients experience limitations resulting in reduced prosthesis use, mobility, and quality of life. Limb-to-prosthesis energy transfer is poor because of the so-called \"pseudojoint\" (i.e., the soft tissue interface), and gross mechanical malalignment is common. Furthermore, transtibial amputees may experience irritation from pistoning and suction at the residual limb-socket interface. These issues result in skin problems and difficulties with socket fit because of fluctuation in the size of the residual limb size, resulting in a decrease in overall satisfaction and confidence in mobility. A bone-anchored implant creates a direct skeletal connection between the residual limb and artificial leg, in which energy transfer is optimal and mechanical alignment is significantly improved.</p>","PeriodicalId":54677,"journal":{"name":"Operative Orthopadie Und Traumatologie","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143450802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
