Feasibility study to determine if microfracture surgery using water jet drilling is potentially safe for Talar chondral defects in a Caprine model

Objective: Surgical microfracture is considered a first-line treatment for talar osteochondral defects. However, current rigid awls and drills limit access to all locations in human joints and increase risk of heat necrosis of bone. Using a flexible water jet instrument to drill holes can improve the reachability of the defect without...

Healing water: using pure water jets to perform bone debridement treatments in orthopedic surgery

Orthopedic surgery is a surgical discipline that is concerned with the treatment<br/>of the musculoskeletal system. Many orthopedic treatments involve cutting or<br/>drilling in bones by using rigid drills or oscillating saws. Using waterjets instead of<br/>conventional instruments can be beneficial due to the absence of thermal damage<br/>and a...

The influence of water jet diameter and bone structural properties on the efficiency of pure water jet drilling in porcine bone

Using water jets in orthopedic surgery to drill holes in bones can be beneficial due to the absence of thermal damage and the always sharp cut. To minimize operating time and the volume of water that is used, the efficiency (volume of removed bone per added volume of water) of the water jet should be maximized. The goal was to study the effect...

The design of an adaptive finger mechanism for a hand prosthesis

Upper extremity prostheses can be divided in two main categories: body powered and externally powered. Human powered devices are controlled by a force that is delivered by the user, which often involves moving a limb. In an externally powered prosthesis the energy is provided by an external powersource, such as a battery. The majority of these...
