What socket design is particularly indicated for patients with short or bony residual limbs?

• A. TT TSB Socket Design
• B. TT PTB Socket Design
• C. TT SCSP Socket Design
• D. Joint + corset design

Answer: (B)

The TT PTB (Transfemoral Partial Tolerance Bearing) socket design is particularly indicated for patients with short or bony residual limbs due to its structural features that allow for effective weight-bearing and control. This design offers a supportive base and distributes pressure more evenly along the residual limb, accommodating the unique anatomy of short or bony limbs which may lack the soft tissue necessary for traditional socket designs. By utilizing a patellar tendon bearing mechanism, this socket facilitates load transfer through the patellar tendon and other key areas of the limb, reducing discomfort and enhancing stability for individuals who may have limited surface area for contact. The PTB socket is specifically tailored to support these patients by promoting better alignment and function, which is critical for mobility and overall prosthetic success. Other socket designs may not provide the same level of support or might place undue stresses on bony areas, leading to discomfort or potential complications. This highlights the importance of selecting the appropriate socket design based on the residual limb characteristics to ensure optimal outcomes in prosthetic fitting and rehabilitation.
