Summary
This study identifies two new types of physeal fractures. One common fracture extends across the metaphysis to the physis, distinct from Salter-Harris type II. The other involves a missing portion of the physis, requiring surgery and often leading to reconstructive procedures.
Area of Science:
- Orthopedic surgery
- Pediatric orthopedics
- Skeletal biology
Background:
- Physeal fractures are common injuries in pediatric patients.
- Existing classification systems may not encompass all fracture types.
- Accurate classification is crucial for appropriate treatment and prognosis.
Purpose of the Study:
- To describe and classify two previously unclassified physeal fractures.
- To detail the characteristics and clinical implications of these novel fracture types.
Main Methods:
- Retrospective analysis of fracture cases from the Olmsted County study.
- Detailed description of fracture morphology and injury patterns.
- Clinical follow-up to assess outcomes and complications.
Main Results:
- A common physeal fracture type was identified, involving metaphyseal extension without physeal longitudinal involvement (15.5% of cases).
- A second, distinct physeal fracture involves a missing portion of the physis, classified as an open fracture.
- This second type consistently requires initial surgical intervention and frequently leads to premature physeal closure and late reconstructive surgery.
Conclusions:
- Two new categories of physeal fractures have been identified and described.
- These classifications enhance understanding of physeal injury patterns.
- Recognition of these fractures is vital for guiding surgical management and predicting long-term outcomes.

01:26Joints
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.

01:18Classification of Bones
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:03Structural Joints: Fibrous Joints
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...

01:20Structural Classification of Joints
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
