Hand
The hand can perform many functions thanks to the existence of 19 bones, 17 joints 19 muscles, without forgetting the forearm tendons that come from. Thanks to the position that keeps the thumb relative to the fingers, the human hand is capable of grasping. Also, is an extremely sensitive and accurate sensory receptor.
The wrist is the body part that connects the forearm (radius and ulna bones) and hand (hueso carpo). It consists of three joints (proximal joint chamber, articulation of the distal external camera and internal articulation of the distal chamber).
Main problems of the hand and wrist
The main pathologies of the hand and wrist leading to the doctor's orthopedic physician and orthopedic surgeon have to do with:
- the sport
- The aftermath of accidents
- Osteoarthritis
- Emergencies (tendons section, broken bones).
Are common:
Stener lesion or Skier
Were due to trauma by excessive stretching of the ligaments of the thumb (specifically ulnar collateral ligament him the ulnar). This lesion is typical for skiers. The thumb is opened too much (forced abduction), causing injury to the domestic joint ligaments (cubital ligament Colateral). You can also occur in falls and other injuries in the thumb is forced laterally. The injury can range from a sprain to a complete tear.
Treatment
Most minor sprains can be treated with splinting and immobilizing the joint for a short period, but when the injury is more serious, surgery is the only solution. It is performed under local anesthesia and after a brief period of immobilization may proceed to the rehabilitation of thumb is usually rapid and satisfactory.
- The trigger finger
- The trigger finger is a pathological condition caused by an inflammation of the tendons that bend the fingers, as tendinitis. To be enlarged, enlarged tendons, causing the fingers can not move normally. It is often a painful process that can produce stiffness of the finger to prevent movement.
Normally usually treated with analgesics, antiinflammatory, physiotherapy exercises, the immobilization even infiltration with steroids in him the finger affected fingers. In the case that the result of this first conservative treatment appears unsatisfactory, may arise perform surgery to widen the area over the inflamed tendons. Usually performed under local anesthesia, so the patient can return home the same day of the operation. During the following days should take care of the wound, to rest and perform prescribed rehabilitation guidelines.
Carpal tunnel syndrome
There is a space in the wrist called the carpal tunnel, where the median nerve and nine tendons pass from the forearm to the hand. Carpal tunnel syndrome is caused by increased pressure on the median nerve at the wrist.
The symptoms may include insensitivity, tingling and pain in the arm, the hand and fingers. It is a common source of pain and numbness of the hands. Although often associated with repetitive hand movements, as the type embroider, Carpal tunnel syndrome can be caused by many things.
The treatment may be included in the first phase, administration of anti-inflammatory drugs, placing a splint that immobilizes the joint or corticosteroid injections. May be advised a change of activity. In the case of this first conservative treatment of a satisfactory result, may consider surgical intervention in most cases is done under local anesthesia and on an outpatient basis. Arthroscopic surgery provides excellent results in this type of intervention.
La Quervain tendonitis
The first dorsal compartment tendonitis, also known as de Quervain tendinitis, is caused by inflammation of the tendons of the wrist at the base of the thumb, often is related to the start of a new repetitive activity.
Its main symptom is pain in the wrist on the thumb side. In some cases, simply disrupt the activities giving rise to the problem allows the symptoms to disappear by themselves.
Treatment
In a first phase, the doctor may order the placement of a splint to immobilize the joint, providing anti-inflammatory drugs and corticosteroid injection even. If symptoms are severe or do not improve with treatment prescribed in the first phase, surgery may be convenient to open the compartment, leaving more room for the inflamed tendons.
El ganglion
The ganglion cyst is a common benign lesion. It is a spherical bulge, usually between one and three inches in diameter that originates in a tendon, in its fibrous sheath or joint capsule. It comprises a covering of collagen fibers containing gelatinous mass.
Many such injuries resolve with time alone, so an option in case of injury is to do nothing and hope it resolves itself, there is also the option to proceed to a syringe aspiration or surgical intervention for removal, in both cases, injury may come back after a while.
FAQ
- What I can do if I snap your finger as is and it hurts, I also noticed a lump in the palm of your hand?
Possibly this is a trigger finger or trigger, treatment is simple releasing the tendon with a small cut, you can go home the same day, local anesthesia is applied and the chances of success are the 99,9%. - I had a fall and broke my wrist, since then it's been months and I can not move well and it hurts, Is there any solution?
After a wrist fracture, although it is well reduced, can form a fibrous tissue creates adhesions and limits the movement of articulation. In this case it is very useful release adhesions using an arthroscopic procedure.
