Do you know about - Mallet Finger
Orthopedic Dr! Again, for I know. Ready to share new things that are useful. You and your friends.What is the cause of mallet finger?
What I said. It is not outcome that the real about Orthopedic Dr. You read this article for facts about an individual want to know is Orthopedic Dr.How is Mallet Finger
It is ordinarily caused by an injury to the tendons ( tendons - are structures which join together muscle to bone and help in movement) which keep the last joint of the finger in a straight position. There are two opposing sets of tendons ( called the flexors and extensors) at the tip of each finger. The first set on the top of the finger helps in lifting the tip ( this movement is called prolongation and therefore this group of tendons are called extensors) and the second on the underside of the finger, help in lowering the tip of the finger ( this movement is called flexion and hence this group of tendons and muscles are called flexors). Hence injury to the tendon that helps in lifting the finger creates an imbalance of forces. This leads to drooping of the tip of the finger. These injuries can be seen with bony fragments. The tendon complicated is called the Extensor Digitorum.
What investigations are needed to diagnose mallet finger?
This is ordinarily a clinical analysis and x-ray is recommended to rule out any bony injury, which may have happened as a succeed of the tendon being pulled out at the site of insertion on the bone. In whether situation, medicine remains the same.
What is the medicine for mallet finger?
The medicine is to immobilize the tip of the affected finger in a special splint, called as the mallet splint.
The splint is made of plastic shaped like a well secured sleeve outside the tip of the finger including the last joint of the finger. It is secured by using tape. It is kept on for a period of six weeks in the first instance.
In case of the deformity lasting after six weeks of splintage, then splintage may be primary for ten to twelve weeks. The patient is advised to take off it only after having kept his hand flat on top of a table, avoiding any bending at the tip and asking an assistant to clean the splint and turn the tape at the bottom.
The patient is followed up by orthopedic doctors in the clinic. Physiotherapy is ordinarily needed to rule stiffness. Surgical repair is not advised as it doesn't ordinarily yield good results. Mallet thumb is treated in the same way as a mallet finger.
If the finger is bent during the healing process, then saving time is delayed.
What are the complications of mallet finger?
They include:
1. Loss of extension
2. Temporary skin problems
3. Difficult patient compliance
4. Refractory bony mallet ( where there is a primary chunk of bone that has come off with the tendon) cases not responding to conservative supervision are treated by open surgical operation if needed.
