Femoral neck fracture after surgery to prevent the method ANFH

Femoral neck fracture surgery after three-Chuang: First, Commissioner of postoperative infection, the test of the majority of patients can be passed, usually around 10 days; Second, the customs union, femoral neck position poor blood circulation, mostly middle-aged and elderly patients, with relatively slow in healing, it normally takes three months to one year or so, the greater the age of Healing more difficult, not about healing rate can reach about 30 percent. Commissioner of the first two terms as doctors and patients, are more seriously, Third, it is ANFH customs, customs that are often easily be ignored. Clinical common situation is: femoral neck fracture after surgery reduction, internal fixation, are healing well, doctors are very satisfied with the patients, so no protection, free activities, The ultimate cause necrosis of the femoral head, leaving life-long regret. Femoral neck fracture of the femoral head necrosis rate of about 20-40%, its risk factors include the following: 1, the fracture site: fracture of the femoral neck and around the femoral head, a non-union and the higher the probability of necrosis of the femoral head; 2, the age: in the femoral neck fractures in elderly patients vulnerable to non-union, femoral neck fracture and young adults prone to osteonecrosis of the femoral head; 3, weight: premature disposable Shui activities led to the universal cause necrosis of the femoral head; 4, dislocation and the degree of reduction and quality: mild femoral neck fracture dislocation, ANFH rate of 15.7 percent, to moderate to 35.7 percent, dislocation, severe compared to 51 percent, reduction of Of the better, osteonecrosis of the femoral head and the lower rate. In order to prevent osteonecrosis of the femoral head should be: 1, diligence review X-ray film, even if the fracture healing, but also track three to five years. Research shows that about 85 percent of the femoral head necrosis occurred three years after the fracture, 98 percent occurred in less than five years . For the femoral neck fracture efficacy of treatment and evaluation, not merely observed that the fracture healing, but follow-up to five years after injury. Such as X-ray films have found traces of a nail, stock Bones highly regressive and transparent with phenomena such as hardening, that the femoral head necrosis has been threatened, should actively take measures to prevent its further development; 2, it is inappropriate to come load. Femoral neck fracture purely from the perspective of fracture healing after 12 weeks basically can load, but because of osteonecrosis of the femoral head in a late start, reduced Weight should have been insisting to 1 to 1.5 years; 3, found an early necrosis of the femoral head should be taken to using drugs, surgery and other appropriate measures to reverse disease.
