Why Can Bone Injuries Heal More Quickly Than Injuries To Cartilage
Cartilage is a specialized type of tissue found in joints and areas that two bones come together. It is made up of specialized cells that live in the midst of proteins and sugars that absorb and release water similar to a sponge. Healthy cartilage helps decrease friction in joints, absorbs shock and protects the ends of the bone. Degradation of ...Read more
Rich blood supply: Because of the lack of blood supply to cartilage, (a new technique to hasten healing of injuries is to introduce fresh blood flow into the area) whereas the marrow in bones actually produce red blood cells, and bones are actually a honeycomb like structure, and they are constantly being taken apart, and rebuilt, microscopic bit by bit. ...Read moreSee 1 more doctor answer
Cell Growth: Cartilage cells, especially the articular cartilage type, are very slow growing cells so they are also very easily damaged and with enough damage these cells die and are replaced with a type of scar tissue that is not a perfect replacement. Bone on the other hand continues to remodel and can ultimately be fully restored. ...Read more
Can too much inflammation from an injury cause more damage than heal the injury? (e.G. Muscle injuries) would this prolong the healing process?
Progress: Is inevitable, as has happened with knee surgery already! lesser and lesser invasive, or new therapies entirely are likely in many areas including orthopedics. ...Read more
Why would an impact injury to the maxilla be more difficult to recover from than a long bone fracture?
Maxilla injury: A facial fracture that is a result of an impact injury may depress the maxilla. This may need to be surgically reduced and fixed. Since the maxilla articulates with the mandible, chewing can be a problem. Long bone fractures can also have problems healing with delayed and nonunion. It depends on the location of the long bone fracture and if it is displaced or not. ...Read more
Sometimes: Most wrist fractures can be treated with cast immobilizaton and will typically heal in about 6 weeks. Sometimes with a sprain one can develop different types of carpal instability which can lead to long term problems like arthritic changes. Swelling and pain. So sometimes a sprain can be worse in the long run than a fracture. ...Read moreSee 1 more doctor answer
Why do finger injuries seem to hurt much more than other injuries? Foot injuries don't seem to hurt as much.
Which of these two tissue types do you think would heal faster following an injury? (a) cartilage or bone?
Always cartilage: The stages of healing bone fractures are: blood clots are organized by chondroblast cells into cartilage. Then invading osteoblasts convert the cartilage in bone structure; which is constantly being remodeled by both osteoclast ; osteoblast cells ; influenced by blood flow ; stress loads. Yet many genetic, epigenetic ; physiologic controls remain poorly understood. ...Read more
ACL/contusion: Acl sprains are a continuum. Minimal sprains may heal in a few weeks, more extensive ones may need reconstruction. A knee contusion should heal in a few weeks. ...Read more
Topaz: Tendon injuries can be difficult to treat. Aside from the normal treatments such as rest, therapy, casting or orthotics, some physicians are turning to topaz. Topaz is a minimally invasive procedure that uses radiofrequency to treat the underlying tendon. In the right patient, topaz could speed up healing times considerably. ...Read more
See below:: Knee is superficial, ie, without much muscle protecting/covering it, while other 2 are deeply located and nicely protected. The knee is easily injured for lack of the muscles; the knee, being a weight bearing joint is prone to twisting injuries, with strains/sprains frequently occurring, many times more so than the other 2. Also knee is an unstable joint with no inherent stability, like the hip. ...Read more
No: Fractures generally heal in about 6 weeks unless there are complications. ...Read more
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
