Causes:
Cutting or Piercing Tools:
Hand injuries with sharp or piercing instruments such as knives, broken glass or piercing objects
Accidents:
Injuries resulting from motor vehicle accidents, household accidents or industrial accidents.
Sporting Injuries:
In some sports, especially those where the hand is used a lot (e.g. cycling, basketball), hand tendon cuts can occur.
Surgical Complications:
Complications during or after surgical interventions.

Non-Surgical Treatment Methods:
First Aid:
It is important to close the wound with a clean cloth or bandage immediately after the injury and control bleeding.
Altitude and Rest:
Keeping the hand elevated and resting it can help reduce swelling and pain.
Cold Packs:
Cold application can reduce swelling and relieve pain.
Retainers or Splints:
Can be used to help tendons heal in the correct position.
Physical Therapy:
Special exercise programs accompanied by a physiotherapist can increase the range of motion and strength of the hand.

Surgical Treatment Methods:
Tendon Repair:
The torn tendon ends are surgically brought together and sutured.
Tendon Transfer:
If the tendon is completely severed, transfer of an intact tendon to the affected area may be considered.
Tendon Graft:
Another tissue (usually another tendon) can be used to replace the severed part of the tendon.
Rehabilitation:

After surgery, rehabilitation programs with a physiotherapist can help restore normal hand function.

Hand tendon lacerations are serious injuries and their treatment is usually managed by a specialized orthopedic surgeon. Depending on the severity and type of injury and the overall health of the patient, the treatment plan is determined.
