Summary
Arthroscopic elbow capsulectomy can achieve significant capsule removal but may leave remnants, particularly posteriorly near the ulnar nerve. Careful technique and portal changes are crucial for complete elbow stiffness treatment.
Area of Science:
- Orthopedic Surgery
- Arthroscopy
- Elbow Biomechanics
Background:
- Post-traumatic or postoperative elbow stiffness, including capsular contracture, limits daily function.
- Arthroscopic arthrolysis with capsulectomy is a treatment option for persistent elbow stiffness.
Purpose of the Study:
- To evaluate the efficacy of arthroscopic capsulectomy in removing elbow joint capsule portions.
- To assess the completeness of capsule removal using an in vitro anatomical study.
Main Methods:
- Standardized elbow arthroscopy with ventral and dorsal capsulectomy was performed on five fresh-frozen elbow specimens.
- Image documentation was used throughout the arthroscopic procedure.
- Open dissection followed to analyze residual capsule and photodocument specimens.
Main Results:
- Anterior and posterior capsule remnants were present in all specimens, irrespective of surgeon experience.
- Dorsal capsule remnants were frequently observed near the dorsolateral camera portal.
- Incomplete posterior capsulectomy occurred near the posterior medial ligament (PML) due to ulnar nerve proximity.
Conclusions:
- Arthroscopic arthrolysis can achieve a high degree of capsule resection, but self-critical assessment is necessary.
- Posterior medial ligament (PML) release via arthroscopy is challenging due to ulnar nerve injury risk.
- Portal modifications may improve visualization and reduce residual capsule, but open techniques may be needed for PML release.

Structural Joints: Synovial Joints
6.8K
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...

Structural Joints: Fibrous Joints
3.8K
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...

Structural Joints: Cartilaginous Joints
4.0K
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
35.7K
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

Method of Joints
1.3K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...

Introduction to Joints
4.8K
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...
