“…Additionally, dorsal osteophytes can be reached, and the finger axis can be partially corrected (Figs. 3,4,5). It gives good access to the collateral ligaments, leaving the option for tightening and reconstruction.…”

“…Pellegrini The palmar approach for PIP-arthroplasty according to Simmen 727 in 26 joints using the dorsal Swanson approach [2]. In a study by Wijk et al with dorsally inserted pyrocarbon implants, the average range of motion decreased from 56°t o 52° [4]. Jennings et al reported a bigger gain of arc of motion using the dorsal compared to the palmar approach of 2°but in a very small population [6].…”

“…Arthrodesis of the joint gives stability especially for the pinch grip [1]. In order to preserve or restore the arc of motion that is needed for the power grasp, a resection interposition or arthroplasty is recommended [2][3][4][5][6][7][8]. Since the Swanson silicone implant was introduced, research is focused on the comparison and development of new implants made of other materials, like titanium-polyethylene or pyrocarbon [9,10].…”

“…Prior work has explored three primary types of medical devices for restoring or enhancing musculoskeletal function: 1) rigid passive implants that directly attach to bones, such as joint-replacement implants [6] or implants for holding bones together after fractures [7]; 2) implants that secure two biological tendons, such as tenofix and ortho-Hunter implants [8], or biological tendons to bone, such as the orthocoupler implant [9]; 3) external devices that are body powered or externally powered, such as prostheses for replacing lost body parts, orthoses for correcting misalignments [10], or exoskeletons for assisting in movement [11]. Recently, there have been devices for directly attaching muscles in a residual limb to external prostheses through surgeries called cineplasty [12].…”

Abstract-This paper explores the development of biomechanical models for evaluating a new class of passive mechanical implants for orthopedic surgery. The proposed implants take the form of passive engineered mechanisms, and will be used to improve the functional attachment of muscles to tendons and bone by modifying the transmission of forces and movement inside the body. Specifically, we present how two types of implantable mechanisms may be modeled in the open-source biomechanical software OpenSim. The first implant, which is proposed for hand tendon-transfer surgery, differentially distributes the forces and movement from one muscle across multiple tendons. The second implant, which is proposed for knee-replacement surgery, scales up the forces applied to the knee joint by the quadriceps muscle. This paper's key innovation is that such mechanisms have never been considered before in biomechanical simulation modeling and in surgery. When compared with joint function enabled by the current surgical practice of using sutures to make the attachment, biomechanical simulations show that the surgery with 1) the differential mechanism (tendon network) implant improves the fingers' ability to passively adapt to an object's shape significantly during grasping tasks (2.74× as measured by the extent of finger flexion) for the same muscle force, and 2) the force-scaling implant increases knee-joint torque by 84% for the same muscle force. The critical significance of this study is to provide a methodology for the design and inclusion of the implants into biomechanical models and validating the improvement in joint function they enable when compared with current surgical practice.Index Terms-Biomechanical modeling, implant design, orthopedic surgery.

“…Most patients are unwilling to accept the donor site morbidity in the foot for such limited motion in the finger and decline that option when offered. When both sides of the joint have lost articular cartilage, but motion is still desired, the remaining options are silicone or surface total joint replacement [1,2,6,7,11,12,15,16].…”

Prosthetic Hemi-Arthroplasty for Post-Traumatic Articular Cartilage Loss in the Proximal Interphalangeal Joint

This article discusses the indications, contra-indications, and technique for proximal interphalangeal joint prosthetic hemi-arthroplasty in the setting of sub-acute or chronic post-traumatic articular cartilage loss. Two case examples are provided: one for replacement of the head of the proximal phalanx, the other for replacement of the base of the middle phalanx.This procedure serves as a recently available alternative to fusion, silicone total joint replacement, total joint arthroplasty with unlinked surface replacements, volar plate arthroplasty, hemi-condylar osteochondral autograft reconstruction, or free vascularized joint transfer.
