Control of Separable Subsystems with Application to Prostheses [PDF]

arXiv, 2019
Nonlinear control methodologies have successfully realized stable human-like walking on powered prostheses. However, these methods are typically restricted to model independent controllers due to the unknown human dynamics acting on the prosthesis. This paper overcomes this restriction by introducing the notion of a separable subsystem control law ...

New Minimally Invasive Method for Treating Posterior Pelvic Ring Fractures: Biomechanical Validation and Clinical Application of Sacroiliac Joint Locking Plate

Orthopaedic Surgery, Volume 17, Issue 5, Page 1433-1446, May 2025.
We propose a minimally invasive, safe, and straightforward technique for internally stabilizing posterior pelvic ring fractures with a sacroiliac joint locking plate (SJP). Our method eliminates the need for intraoperative fluoroscopy. (A,B) SJP morphology and fixation position. (C) Postoperative imaging.

Continuous Wrist Control on the Hannes Prosthesis: a Vision-based Shared Autonomy Framework [PDF]

arXiv
Most control techniques for prosthetic grasping focus on dexterous fingers control, but overlook the wrist motion. This forces the user to perform compensatory movements with the elbow, shoulder and hip to adapt the wrist for grasping. We propose a computer vision-based system that leverages the collaboration between the user and an automatic system in

Degenerative Hip Osteoarthritis in Unilateral Knee Osteoarthritis Patients: A Correlation Analysis

Orthopaedic Surgery, Volume 17, Issue 4, Page 1201-1208, April 2025.
(a) The picture show that the KL grade of left hip joint was 4. (b) The picture show that the KL grade of the right knee was 4. ABSTRACT Objective Hip and knee OA often occur successively. However, little is known about the relationship between hip and knee OA in unilateral knee OA patients.

The 3D‐Printed Customized Femoral Short Stem Offers Improved Anatomical Parameters Restoration, Fitness and Biomechanical Performance Compared With Traditional Femoral Stem

Orthopaedic Surgery, Volume 17, Issue 4, Page 1220-1229, April 2025.
3D‐printed customized femoral short stem can preserve more cancellous bone in the proximal femur while achieving higher fitness with the medullary cavity. ABSTRACT Objective The traditional femoral stem is unsuitable for patients with severe proximal femoral bone defects or deformities.
