Abstract
Description
Technical Field
[0001] The present application relates to the technical field of orthopedic rehabilitation equipment, and in particular to an external fixation bracket for distal radius fractures. Background Art
[0002] Distal radius fracture is a common type of fracture, usually occurring in the wrist. This fracture is common in the elderly and osteoporotic patients, and may also be caused by falls, sports injuries or other external forces. In the past, the treatment of distal radius fractures mainly relied on traditional manual reduction and external fixation. However, this method may have problems such as inaccurate reduction and unstable fixation, resulting in poor fracture healing or sequelae. In recent years, with the continuous advancement of medical technology, there are more options for the treatment of distal radius fractures. For example, internal fixation surgery can provide more accurate reduction and more stable fixation, which is conducive to fracture healing and rehabilitation. In addition, the development of imaging technology, such as X-rays and CT scans, also provides doctors with more detailed fracture assessments, which helps to develop more individualized treatment plans. At the same time, rehabilitation therapy also plays an important role in the recovery after distal radius fractures. Physical therapy, rehabilitation training, etc. can help patients restore wrist function and reduce the occurrence of complications. In general, the background technology of distal radius fractures covers multiple aspects from diagnosis to treatment and rehabilitation. The continuous development of technology and treatment methods provides patients with better treatment effects and rehabilitation opportunities. However, during the treatment process, the doctor will choose the most suitable treatment plan based on the patient's specific situation.
