Safety, prosthesis wearing time and health-related quality of life of lower extremity bone-anchored prostheses using a press-fit titanium osseointegration implant: A prospective one-year follow-up cohort study

“…Better patient selection, improved surgical technique, implant design and better understanding of daily loading profile might play a key role in reducing adverse events associated with OTI treatment. [25] Although the number of infectious soft tissue events in the group treated with a tibial OI was higher compared to the group treated with a femoral OI, this did not affect the quality of life and prosthetic use scores in the tibial OI group. We assume that the temporary and mild aspect of the infectious soft tissue events ultimately have no effect on the quality of life and prosthetic use scores.…”

“…[26] Fifth, there is little insight in confounders such as loading during daily living or alignment of components used, possibly associated with certain adverse events; such as the four DCA breakages that occurred. [25] Earlier research in individuals treated with screw-type implants revealed potential limitations of load monitoring, differences in loading compliance, and benefits of using certain instruments to monitor static load bearing. [27][28][29] Future research should be performed to gain more insight in the effects of load bearing, during the rehabilitation time and in daily living with regard to adverse events such as component breakages and the effects of modifications of soft tissue surgical technique of the stoma with regard to soft tissue adverse events.…”

Inter-participant variability data in loading applied on osseointegrated implant by transtibial bone-anchored prostheses during daily activities

“…Participants fitted with transtibial bone-anchored prostheses including with their own or Free-Flow prosthetic foot performed three and five trials of five standardized daily activities including straight-line level walking (5–10 m walkway), ascending and descending ramp (2.5 m, 13.7 deg incline) and stairs (3 stairs, 20 cm height, 24.5 cm deep, 100 cm wide) following protocol previously used for individuals with transfemoral amputation [1], [2], [3], [4], [5], [6]. Participants were instructed to complete each activity at a self-selected comfortable pace as well as to use handrails and take sufficient rest between trials to avoid fatigue if needed.…”

The Influence of Geometry of Implants for Direct Skeletal Attachment of Limb Prosthesis on Rehabilitation Program and Stress-Shielding Intensity

“…However, the use of patient's specific bone internal features would introduce additional variables that could make the results less common. More limitations result from considering specified loading method that can vary significantly if different prosthetic components are used or different patient-specific loads are examined [4, 5]. Moreover, the data is also affected by straight insertion of implants in the bone shaft, while clinically it is also often placed at an angle, making Gruen zones asymmetrical.…”

“…The research can be further developed with consideration of different type of prosthesis' components, which have significant influence on the loads generated on the head of the implant [4, 5]. In the future the authors consider conducting in vitro research in order to confirm the functionality of the presented implant.…”
