Purpose: The purpose of this study was to conduct a systematic review evaluating the reported complications and outcomes of bone-anchored prostheses in digit and partial hand amputees.
Methods: A literature review of primary research articles on osseointegration and bone-anchored prostheses for digit and partial amputees was performed. The Medline, Embase, Scopus, and Cochrane Library databases were queried. Inclusion criteria were journal articles that evaluated osseointegration and bone-anchored prostheses in digit and partial hand amputees. The main outcome measures were reported complications and the need for revision surgery. Secondary outcomes included all reported outcome assessments.
Results: Fifteen articles were included with publication dates ranging from 1996 to 2022. The sample sizes ranged from single-patient case reports to a 13-patient retrospective study. Overall, 33 men and 16 women were reported with a mean age of 33.6 years (range: 12-68) and a total of 71 amputated digits. The median follow-up was 2.1 years (IQR: 1.1-6.8 years). A total of 24 complications were reported in 14 digits (19.7%). Complications included superficial infection in 6 digits (8.5%), abutment loosening or failure in 5 (7%), fixture aseptic loosening in 4 (5.6%), deep infection in 1 (1.4%), and soft tissue instability in 1 (1.4%). Sixteen revision surgeries or component changes were reported.
Conclusions: Bone-anchored prostheses using osseointegrated implants in the hand are associated with favorable outcomes in the limited number of low-quality studies available for review. Superficial infections and implant-related failures were the most frequently reported complications.
Type Of Study/level Of Evidence: Systematic review IV.

Article Synopsis
- Patients with transfemoral amputation often face issues related to socket fit and overuse injuries due to uneven joint stress, which can be improved by using bone-anchored prosthetics that connect directly to the bone.
- This study investigates the relationship between the alignment of the femur and pelvis and how it impacts hip loading asymmetry during walking, both before and one year after receiving a bone-anchored limb implant.
- The analysis included 19 participants from a larger group who underwent the surgery, comparing their skeletal alignment and hip motion data collected at two different time points to determine the effects of the implantation on their mobility and joint loading.

Background: Direct skeletal fixation, a surgical technique enabling the attachment of an external prosthesis directly to the bone through a percutaneous implant, offers an enticing solution for patients with lower limb amputations facing socket-related issues. However, understanding of its impact on musculoskeletal function remains limited.
Methods: This study compares pre- and 1-year post-osseointegration surgery outcomes, focusing on patient-reported measures and musculoskeletal system function during level-ground walking.

Bone-anchored percutaneous implants, commonly referred to as osseointegrated implants, are gaining popularity as an alternative to sockets for attaching a prosthetic limb to an amputated femur. While these implants have several advantages, femoral fractures are relatively common in these patients, occurring in 6.3% of femurs within 4 years.
