Bent fingers may heal, mainly related to the cause of the bend. There are four main causes of bent fingers: trauma, tenosynovitis, degenerative lesions of old age and congenital diseases. If it is caused by trauma, it can be examined by X-ray for fracture, and the treatment plan will be determined according to the injury, which can be recovered after surgery or manipulation. If it is caused by tenosynovitis, it can be recovered after treatment with rest, heat, acupuncture or incision and decompression. If it is due to senile degenerative lesions, joint bending and finger bending will occur, and it will usually be progressively aggravated and difficult to recover. If it is due to congenital disease, resulting in skin and muscle contracture, so that the finger is in passive flexion, usually can not be restored. If you have a bent finger, you should go to the hospital at the first time for early diagnosis and treatment.
