Introduction/Objective. The essence of the treatment degenerative knee joint diseases is pain relief, restoring motion range and stability joints. Methods. In this study, 35 patients participated after having surgery joint. had a posterior-stabilized (PS) endoprosthesis in one joint, posterior cruciate ligament retaining (CR) other. Kinematic data was collected using 3D optical system for track...

Poor suspension increases slippage of the residual limb inside the socket during ambulation. The main purpose of this article is to evaluate the pistoning at the prosthetic liner-socket interface during gait and assess patients' satisfaction with two different liners. Two prostheses with seal-in and locking liners were fabricated for each of the 10 subjects with transtibial amputation. The Vico...

The purpose of this study was to determine the relationship between stride-to-stride fluctuations and prosthesis preference. Thirteen individuals with unilateral, transtibial amputation consented to participate. Individuals walked on a treadmill for 3 min with their prescribed and an alternate prosthesis. Stride-to-stride fluctuations were quantified with the largest Lyapunov exponent (LyE) of ...

This paper describes the genesis of the Rapidform process and its pioneering place in the new developments leading to complete control of the processes of manufacture of prostheses. The materials and geometric considerations involved in the development of a double deformation process under microprocessor control are described. Stages in the development of the system show the advance from the in...

Traditionally, prosthetic leg research has focused on improving mobility for activities of daily living. Artistic expression such as dance, however, is not a common research topic and consequently prosthetic technology for dance has been severely limited for the disabled. This work focuses on investigating the ankle joint kinetics and kinematics during a Latin-American dance to provide unique m...

Over time, leg prostheses have improved in design, but have been incapable of actively adapting to different walking velocities in a manner comparable to a biological limb. People with a leg amputation using such commercially available passive-elastic prostheses require significantly more metabolic energy to walk at the same velocities, prefer to walk slower and have abnormal biomechanics compa...

Introduction: Although the results of anterior cruciate ligament (ACL) reconstruction are well documented in many studies, with good to excellent outcomes in most cases, some issues like tunnel positioning are still discussed and studied. Objective: To compare the objective and subjective clinical outcomes of ACL reconstruction using the transtibial and anteromedial portal techniques. Methods: ...

Background and Objectives: Supracondylar fractures of the humerus are the most common fracture pattern of the elbow in children. Severely displaced supracondylar fractures of the distal humerus in children are a challenging problems. Many treatment methods have been described for the treatment of displaced supracondylar fractures of the humerus, however, it has not been reached a consensus for ...

The emergence of skeletal prosthetic attachments leaves governmental organizations facing the challenge implementing equitable policies that support provision bone-anchored prostheses (BAPs). In 2013, Queensland Artificial Limb Service (QALS) started a five-year research project focusing on health service delivery and economic evaluation BAPs. This paper reflects QALS experience, particularly l...
