Starr-Edwards Mechanical Prosthesis for More Than 53 Years in the Mitral Position: A Case Report

International Journal of the Cardiovascular Academy
Valvular heart disease affects approximately 2.5% of the global population. Starr-Edwards (SE) prosthetic valves are commonly used in the aortic and mitral positions, with reported durability extending up to 40 years.

Analysis of the Mechanical Behavior of the Nijdam Voice Prosthesis [PDF]

The Laryngoscope, 1997
AbstractThe valveless Nijdam prosthesis is a new voice prosthesis for laryngectomized patients using tracheoesophageal speech. An “umbrella‐like hat” covers the esophageal side of the tracheoesophageal fistula and is deformed during speech by air pressure.

Mechanical properties evaluation of metacarpophalangeal joint prosthesis with new titanium-nickel memory alloy: a cadaver study

BMC Musculoskeletal Disorders, 2023
Objective Ni-Ti memory alloys are unusual materials for hard-tissue replacement because of their unique superelasticity, good biocompatibility, high strength, low specific gravity, low magnetism, wear resistance, corrosion resistance and fatigue ...

[Mechanical complications of total shoulder inverted prosthesis].

Revue de chirurgie orthopedique et reparatrice de l'appareil moteur, 2002
Our series of inverted prosthesis included 5 patients with a mean age of 73 +/- 6 years. In 4 cases, the implant was performed as a surgical revision. The follow up was 81 +/- 15 months. Three shoulders were pain free whereas two caused a dull pain after a free interval due to mechanical complications.

The mechanics of the knee and prosthesis design [PDF]

The Journal of Bone and Joint Surgery. British volume, 1978
The mechanisms controlling and limiting movement and serving to transmit load between the femur and the tibia are discussed. Having accounted for the transmission of all components of force and couple across the joint and noted the load-bearing role of the menisci, some principles which might guide the design of knee prostheses are deduced.

Development of Mechanism for Finger Prosthesis [PDF]

Acta Mechanica Slovaca, 2020
Nowadays prosthetic fingers provide not only a cosmetic solution to the problem, but mainly they provide function. 3D printing is an ideal technology for the manufacturing of low-cost prostheses, especially the upper limb prosthetics. The advantages offered by this technology make it possible to increase the level of creativity, personalization and at ...

Prosthetic rehabilitation of resected orbit in a case of mucormycosis

The Journal of Indian Prosthodontic Society, 2018
The design of orbital prosthesis to rehabilitate patients with orbital exenteration depends on the underlying clinical condition, material chosen for prosthesis, method of retention of the prosthesis, and and preference of the patient.

Shoulder Prosthesis Mechanics [PDF]

The Journal of the Korean Shoulder and Elbow Society, 2010
Purpose: The goal of prosthetic replacement of the shoulder is the restoration of the normal anatomy of the joint. Materials and Methods: The physician should review the variations in normal anatomy because it does vary widely and the placement of the prosthetic needs to be modified to accommodate the variations. Results and Conclusion: Several factors
