After the hand fracture healing, it is common to have a very sore local condition, mainly because after the fracture healing, the local function is not fully recovered, and the local ligaments, fascia, soft tissues and tension are not fully recovered, and the local venous power is not recovered, thus causing the local soreness and discomfort. After the fracture requires a certain period of immobilization and rest, the local soft tissues will undergo pathological changes such as adhesions, scarring, and mechanization, resulting in tissue contracture and a decrease in local elasticity. After the fracture is healed and the corresponding functional training is carried out, the local soft tissues will be strained, and the veins will be weaker due to the prolonged immobilization, and the venous atrophy will also cause the corresponding poor circulation, which will cause local soreness and discomfort in the early stage of post-fracture activities. After several months of functional exercise and recovery, the symptoms will gradually disappear.
