After comminuted fracture of little finger joint, the bottom joint becomes bigger and deformed, the reason may be soft tissue changes such as joint capsule, traumatic arthritis, non-union of fracture and so on.
1. Soft tissue changes such as joint capsule: the bottom joint may be enlarged and deformed due to the damage caused by the fracture, such as hypertrophy and swelling of the joint capsule and other soft tissues of the interphalangeal joints of the proximal phalanx.
2. Traumatic arthritis: the joint surface becomes uneven due to fracture of the little finger joint, which causes inflammation of the proximal joint due to uneven force during gradual activities, thus leading to swelling and deformity of the local joint area.
3. Non-union of fracture: commonly seen in comminuted fracture of little finger joint, due to impaired blood supply, non-union of joint can occur, after a longer period of time, the proximal interphalangeal joint bone formation expansion, sclerosis and other changes.
Patients with comminuted fracture of the little finger joint at the bottom of the joint becomes large and deformed are recommended to consult a doctor in time, with the help of the doctor to clarify the cause of the disease, and to carry out targeted treatment or therapy.
