Summary
Proximal fifth metatarsal fractures, including Jones fractures, have varied healing potential based on their zone. Zone 1 fractures heal well nonoperatively, while Zone 3 fractures often need surgery.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Podiatry
Background:
- Proximal fifth metatarsal fractures are common injuries.
- Treatment is debated due to unclear fracture subtype nomenclature.
- The term "Jones fracture" encompasses proximal fifth metatarsal fractures in zones 2 or 3.
Purpose of the Study:
- To clarify the nomenclature and treatment implications of proximal fifth metatarsal fracture subtypes.
- To differentiate treatment strategies based on fracture zone.
Main Methods:
- Review of current literature on proximal fifth metatarsal fractures.
- Classification of fractures into distinct zones (1, 2, and 3).
- Analysis of healing potential and treatment outcomes for each zone.
Main Results:
- Zone 1 fractures demonstrate excellent healing potential with nonoperative, weight-bearing as tolerated protocols.
- Zone 2 fractures represent acute injuries with unclear optimal treatment.
- Zone 3 fractures are associated with chronic stress reactions and typically require operative intervention due to poor healing potential.
Conclusions:
- Accurate classification of proximal fifth metatarsal fractures into zones is crucial for guiding treatment.
- Zone-specific treatment protocols can optimize outcomes for these common injuries.

01:27Fractures: Bone Repair
4.3K
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...

01:12General Case of Eccentric Axial Loading
348
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...

01:27Compact Bone
15.0K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:10Ankle Joint
2.3K
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...

01:29Bone Disorders
4.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:22The Functions of the Skeletal System
5.3K
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...
