压力 骨折
Overview
A stress fracture is a small crack in a bone. They often develop from overuse, such as from high-impact sports like distance running or basketball. When muscles are overtired (fatigued), they are no longer able to absorb the shock of repeated impacts. When this happens, the muscles transfer the stress to the bones, creating a small crack or fracture.
Most stress fractures occur in the weight-bearing bones of the foot and lower leg. The most common sites are the second and third toes (metatarsals) of the foot. 压力 fractures are also common in the heel (calcaneus), the outer bone of the lower leg (fibula), 舟状骨, 足中部上部的骨头.
我们研究应力性骨折的方法
压力 fractures generally heal on their own with simple measures, such as avoiding activities that put stress on the area. In some cases, however, surgery is needed to help the fracture heal properly.
Many stress fractures occur in the foot or lower leg. Our team includes highly trained orthopedic surgeons who specialize in that area, 还有足科十大赌博平台排行榜, physical therapists and pedorthists (specialists in modified footwear and supportive devices for the lower leg).

迹象 & 症状
迹象 and 症状 of a stress fracture may include:
- Pain that develops gradually, increases with weight-bearing activity, and diminishes with rest
- Pain that becomes more severe during normal, daily activities
- 肿胀
- Tenderness to touch and possible bruising
诊断
压力 fractures are difficult to see on X-rays until they have actually started to heal. Your doctor may recommend a bone scan, which is more sensitive than an X-ray and can detect stress fractures early.
治疗
Treatment depends on the location of the stress fracture. Most stress fractures will heal if you reduce your level of activity and wear protective footwear for 2 to 4 weeks. Your doctor may recommend that you wear a stiff-soled shoe, 木底凉鞋, or a removable short-leg fracture brace shoe. Athletes should switch to activities that place less stress on the foot and leg. Swimming and bicycle riding are good alternative activities.
压力 fractures in the fifth metatarsal bone (on the outer side of the foot) or in the navicular or talus bones (the bone that forms the lower part of the ankle joint) take longer to heal, 可能长达6到8周. Your doctor may apply a cast to your foot or recommend that you use crutches until the bone heals. In some patients, surgery may be needed to ensure proper healing.
