Navicular fracture of the wrist is a common fracture of the wrist, due to the special anatomical structure of the navicular bone and poor blood flow. In recent years, with the aid of high definition bedside X-ray machine (C-ARM), we have adopted the minimally invasive technique of closed reduction hollow compression screw internal fixation for navicular fracture based on many years of experience in incision and internal fixation of navicular fracture, which is minimally invasive. The treatment of navicular fracture is minimally invasive, fast, with short postoperative fixation time and fast patient recovery, and achieved good clinical results. Significantly improve the postoperative recovery effect of navicular fracture, improve the postoperative comfort, the basic postoperative scarless, special to everyone: Peking University Shenzhen Hospital hand, microsurgery Zhou Hammer wrist navicular fracture is a common fracture in hand surgery, hand navicular fracture if it occurs in the waist or near 1/3 of the navicular bone, due to intraosseous nutrient vessels break, easy to cause delayed bone healing or non-healing. The navicular fracture sometimes only shows mild chronic pain in the wrist, and there may be no fracture in the early stage of ordinary X-ray examination. It is easy to delay the diagnosis or miss the diagnosis. Fractures that do not heal require prompt formal treatment. Otherwise, non-healing of old fractures may lead to ischemic necrosis of the navicular bone and traumatic arthritis of the wrist joint. Clinical manifestations: acute injury with a history of wrist trauma, pain on the thumb side of the wrist, swelling, and limitation of movement. In the chronic phase, there is no swelling, but most of the wrist has chronic pain on the lateral side of the thumb. x-ray examination: navicular fracture is visible as a fracture line, as shown in the figure under the operation of high-definition bedside x-ray machine detection. It is quick, easy and safe. The surgery is basically incisionless and there is basically no scar after surgery It is recommended to see my expert clinic for good results of fresh navicular fracture surgery.
