Summary
Titanium chest wall prostheses can fracture, even those using locking screws. Patients in contact sports need to be informed of this risk and potential need for surgical removal.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Thoracic surgery
Background:
- Titanium prostheses are increasingly used for chest wall reconstruction.
- Previous complications involved clip-secured systems; locking screw systems were thought more robust.
Observation:
- A titanium plate, secured with locking screws, fractured 25 months post-implantation.
- Fracture occurred after direct chest impact during sports.
Findings:
- Locking screw titanium systems can fail.
- Fracture necessitates surgical excision due to persistent pain and cough.
Implications:
- Patients undergoing chest wall reconstruction with titanium plates should be counseled on fracture risks, especially if active in contact sports.
- Informed consent must include the possibility of implant failure and subsequent surgical removal.

Fractures: Bone Repair
5.8K
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...

Flail Chest-II

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

The Thoracic Cage: Ribs
11.3K
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal...
