Summary
Thumb interphalangeal joint replacement offers short-term pain relief and motion preservation for osteoarthritis. However, long-term concerns include implant loosening and joint blockage, necessitating further investigation.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Arthrodesis is the standard treatment for symptomatic thumb interphalangeal (IP) joint osteoarthritis.
- Motion-conserving alternatives are sought for managing this condition.
Purpose of the Study:
- To evaluate the efficacy and safety of interphalangeal (IP) joint replacement using the SR-PIP prosthesis for thumb osteoarthritis.
- To assess pain relief, range of motion, and radiological outcomes.
Main Methods:
- Retrospective case series of 7 thumbs in 5 patients undergoing off-label SR-PIP prosthesis implantation.
- Postoperative assessment included pain, range of motion, and radiological evaluation for osteolysis and ossification.
Main Results:
- Most patients experienced satisfactory pain relief and improved range of motion postoperatively.
- One patient required revision surgery due to recurrent joint instability.
- Radiological findings revealed periprosthetic osteolysis and periarticular ossifications in some cases.
Conclusions:
- Thumb interphalangeal joint arthroplasty with the SR-PIP prosthesis is a viable short-term option for osteoarthritis.
- Long-term sustainability requires further investigation due to observed radiological complications.

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:16Structural Joints: Synovial Joints
6.0K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
