Summary
Reverse shoulder arthroplasty treats complex shoulder issues like rotator cuff and bone deficiencies. Bone grafting techniques using the humeral head or iliac crest provide reliable solutions for glenoid bone loss in reconstructions.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Reverse shoulder arthroplasty (RSA) is a key surgical option for complex shoulder pathologies.
- Rotator cuff and significant glenoid bone deficiencies present unique challenges in RSA.
Purpose of the Study:
- To outline a treatment strategy for RSA in the presence of glenoid bone loss.
- To identify reliable bone grafting sources for glenoid reconstruction.
Main Methods:
- Classification of glenoid bone wear patterns.
- Utilizing structural bone grafts for glenoid reconstruction.
- Surgical technique for primary and revision RSA with bone grafting.
Main Results:
- A systematic approach to glenoid bone loss management in RSA is presented.
- Native humeral head and iliac crest bone grafts are effective for glenoid reconstruction.
- RSA can successfully address severe bone deficiencies.
Conclusions:
- RSA is effective for shoulders with rotator cuff and bone deficiencies.
- Bone grafting is crucial for reconstructing deficient glenoids in RSA.
- A structured approach improves outcomes for complex RSA cases.

01:55Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

01:40Bone Remodeling
40.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:27Compact Bone
16.8K
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...

01:29Bone Disorders
5.5K
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...

01:12The Hyoid Bone
5.3K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

01:09Spongy Bone
8.1K
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...
