Summary
Finding the ideal implant for the first metatarsophalangeal joint (1st MTPJ) remains a challenge. While older implants often fail, HemiCap implants show promise for pain relief and motion preservation in select patients.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Podiatric medicine
Background:
- The first metatarsophalangeal joint (1st MTPJ) is crucial for foot function.
- Its unique biomechanics present challenges for implant arthroplasty.
- Previous implant designs often lead to failure and bone loss.
Purpose of the Study:
- To evaluate the efficacy of implants for the 1st MTPJ.
- To identify optimal implant solutions for pain relief and motion preservation.
- To assess the potential of HemiCap implants in specific patient populations.
Main Methods:
- Review of existing literature on 1st MTPJ implants.
- Analysis of implant failure modes and associated bone loss.
- Evaluation of clinical outcomes for HemiCap implants.
Main Results:
- Many traditional metallic and silastic implants have demonstrated high failure rates.
- Significant bone loss is a common complication with older implant types.
- HemiCap implants have shown potential benefits in select cases.
Conclusions:
- Developing effective implants for the 1st MTPJ is an ongoing goal.
- HemiCap implants may offer a viable option for patients seeking to maintain 1st MTPJ motion.
- Further research is needed to optimize implant design and patient selection.

01:16Structural Joints: Synovial Joints
6.4K
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...

01:03Structural Joints: Fibrous Joints
3.6K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

01:17Structural Joints: Cartilaginous Joints
3.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable

00:58Introduction to Joints
4.7K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...
