Bone bumps at finger joints may be caused by trauma hematoma, fracture and deformity healing, rheumatoid arthritis, bone tumor, etc. The treatment includes manipulation of reset, physical therapy, medication and surgery. 1. Rheumatoid arthritis: Bone bumps at finger joints caused by rheumatoid arthritis require anti-rheumatic treatment to control the inflammatory reaction, such as ibuprofen, salicylazosulfapyridine, biologics, etc.; the above medications need to be used under the guidance of a doctor to avoid self-medication. 2. Traumatic hematoma: Bone protrusion caused by trauma requires ice, braking and elevation of the affected limb in the acute stage, and hot compresses, massage and physiotherapy can be chosen in the relieving stage to accelerate the subsidence of edema. 3. Fracture and deformity healing: Bone protrusion at finger joints caused by fracture needs to be reset by manipulation, and after reset, it needs to be fixed by plaster or brace; patients with deformity healing after fracture without obvious symptoms are not intervened routinely. 4. Bone tumors: for patients with bone tumors leading to raised bones at the finger joints, surgery is the first choice of treatment, and the surgical methods include tumor resection, osteotomy, etc. The specific surgical methods need to be decided according to the original disease. For the same disease, patients with different physical conditions and different stages of the disease have different treatment methods, which should be standardized under the guidance of doctors.
