What are the causes of flexor tendon injury in hand?

summary

The flexor tendon of fingers plays an important role in the function of hand holding. Its anatomical structure is special and suitable for its physiological function. Therefore, the repair of flexor tendon has its particularity. What are the causes of flexor tendon injury in hand? Next, I'd like to share my views with you.

What are the causes of flexor tendon injury in hand?

After tendon rupture, due to muscle contraction, the proximal end of the tendon may retract, even far away. If the tendon is cut at the proximal phalanx, the end of the tendon may retract back to the palm. When the tendon is injured, the fingers are often flexed and grasped. After the injury, the distal broken end moves forward again after the joint is straightened. It is difficult to find both ends in the operation, and it is also difficult to repair. Due to the tension after suture, the suture can be separated and cracks appear, affecting the healing.

There is no bleeding blood vessels in the tendon. It has been controversial whether the tendon can heal like other tissues. Exogenous healing theory has dominated for a long time. It holds that tendons lack self healing ability and need to grow into granulations from the surrounding tissues with abundant blood supply to repair them. Especially in the area with sheath tube, the sheath tube affects the granulation growth, and the part must be removed to make the tendon heal.

Scar formation causes tendon adhesion and affects tendon sliding function, which is an inevitable consequence after tendon repair. Therefore, in the sheath part, especially in area II, the initial treatment is limited to the repair of surrounding skin and soft tissue, and the late tendon transplantation is used to reconstruct the flexure function.

matters needing attention

Hand flexor tendon injury which food to eat good for the body: should be light based, reasonable diet. Vegetarianism is reasonable. The three major nutritional elements of sugar, fat and protein are very rich, which are enough for the reasonable needs of human body.
