Summary
The proximal scaphoid bone has higher bone mineral density (BMD) than other parts, potentially explaining why proximal pole fractures heal poorly. Understanding BMD distribution aids scaphoid fracture treatment.
Area of Science:
- Orthopedics
- Radiology
- Anatomy
Background:
- The scaphoid bone is crucial for wrist function.
- Proximal pole scaphoid fractures have higher nonunion rates, possibly due to bone mineral density (BMD) variations.
- BMD distribution in intact scaphoids is not well understood.
Purpose of the Study:
- To map the bone mineral density (BMD) distribution in intact scaphoid bones.
- To investigate the relationship between BMD and scaphoid fracture etiology and nonunion.
- To inform optimized treatment strategies for scaphoid fractures.
Main Methods:
- Computed tomography (CT) was used to assess BMD in 100 individuals.
- BMD measurements were taken in the distal, middle, and proximal thirds of the scaphoid.
- Data were analyzed using SPSS, with significance set at P < .05.
Main Results:
- The proximal third of the scaphoid demonstrated significantly higher BMD (542.2 HU) than the middle (293.1 HU) and distal thirds (298.4 HU).
- Males exhibited higher BMD, particularly in proximal and distal regions.
- A weak negative correlation was found between age and BMD across all scaphoid sections.
Conclusions:
- The proximal scaphoid's higher BMD may explain its lower fracture incidence but higher nonunion rates.
- Understanding intact scaphoid BMD distribution is key for managing scaphoid fractures.
- Targeted treatment strategies considering BMD variations are needed for scaphoid fractures.

01:18The Bone Matrix
3.0K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

01:27Compact Bone

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...

01:09Spongy Bone
4.1K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:29Bone Disorders
3.4K
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...

01:31Essential Minerals for Bone Health
3.8K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

4.4K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
