It was reported this morning by Scott Wolf that Broderic Green has a stress fracture in his foot, with a potential season ending injury.
Green's injury dealt a blow to USC's depth at running back and means sophomore Stafon Johnson is the only tailback on the roster who did not experience an injury in training camp.
Green said he did not know when he hurt his foot but felt pain for the past 10 days.
"I don't have a clue (how I got hurt)," Green said. "It is frustrating."
Green was visibly upset when he heard the news of the injury and did not want to comment further. The freshman could miss the season with the injury.
Green gives the classic answer in saying that he has no clue as to how he got the injury most every day people don't know when they get an injury like this so imagine when an athlete gets one. It is frustrating. So lets look at this injury.
The Stress Fracture
I liken this injury to the saying "you can't get a little bit pregnant" plain and simple a fracture is a fracture. The classic fracture as we know it usually happens due to some sort of blunt force trauma. For example, a Colles fracture of the wrist occurs when someone falls and they fall on their out stretched hand with enough force to break their wrist. In that case you can see a definite cause and effect of the injury.
A stress fracture to me is a bit of a bad actor and is fairly common within some groups of athletes, esspecially those involved in running or jumping type sports. Often times you don't even know you have it or how you got it until the pain becomes unbearable. They are also hard to diagnose with traditional x-rays, as it usually takes a CT Scan or MRI to identify the injury.As an avid runner 10-or-so years ago I had the wonderful experience of getting a stress fracture in my hip. I went to an orthopedic surgeon who I know well and trust and he was sure that I had a stress fracture but it took two CT Scans and one MRI to find it. His major concern was the location and severity of the "stress" fracture and while he was fairly certain that it could be treated conservatively he wanted to rule out the possibility of need prophylactic surgery to support the fracture. Thankfully it wasn't a sever injury but had I kept running or kept "playing through the pain" this could have turned into a significant injury. I was on the shelf, on crutches for 12 weeks. Once I was cleared to return I went back to running but decided that the risks were too great and a year later I gave it up.

Stress fractures are a type of overuse injury. These tiny cracks in your bones develop when your muscles become overtired (fatigued) and can no longer absorb the shock of repeated impacts. When this happens, the muscles transfer the stress to the bones, creating a small crack or fracture.
Stress fractures also can occur with normal usage if osteoporosis or some other disease weakens your bones and leaves them vulnerable. These fractures are often called "insufficiency fractures" because there isn't enough bone to withstand the normal stress of daily use.
Most stress fractures occur in the weightbearing bones of the foot and lower leg. The most commonly affected site is the second or third of the long bones (metatarsals) between the toes and the midfoot. Stress fractures also can occur in the heel, the outer bone of the lower leg (fibula) and the navicular, a bone on the top of the midfoot.
Who's at risk?
* Athletes who participate in high-impact sports such as track and field, basketball, gymnastics, ballet or tennis
* Adolescents whose bones have not yet fully hardened
* Women, particularly female athletes, who have abnormal or absent menstrual cycles that can result in decreasing bone mass
* Military recruits who suddenly must shift from a sedentary civilian life to a more active training regime
Causes of stress fractures
Doing too much too soon is a common cause of stress fractures. Runner who have been confined indoors for most of the winter may want to pick up where they left off at the end of the previous season. Instead of starting slowly, they try to match their previous mileage. The result could be stress fractures in the foot and ankle.
Improper sports equipment, such as shoes that are too worn or stiff, also can contribute to stress fractures. A change of surface, such as going from a grass tennis court to one of clay or from an indoor to an outdoor running track, can increase the risk of stress fractures. Errors in training or technique are another cause of stress fractures. Some conditions, such as flatfoot or bunions, can change the mechanics of your foot and make stress fractures more likely to develop.
Insufficiency stress fractures result when the bone itself is weak. Conditions such as osteoporosis reduce the density and quality of bone matter, thus increasing the risk of fracture. Female athletes who experience irregular or absent menstrual periods may also have decreased bone density and an increased risk of stress fractures.
Signs and symptoms
* Pain that develops gradually, increases with weight-bearing activity, and diminishes with rest
* Swelling on the top of the foot or the outside ankle
* Tenderness to touch at the site of the fracture
* Possible bruising

If you suspect a stress fracture in your foot or ankle, stop the activity and rest the foot. Ignoring the pain can have serious consequences, and the bone may break completely. Apply an ice pack and elevate the foot above the level of your heart. Try not to put weight on the foot until after you see a doctor.
Stress fractures are difficult to see on X-rays until they've actually started to heal. Your orthopaedist may recommend a bone scan, which is more sensitive than an X-ray and can detect stress fractures early.
Treating stress fractures
Treatment will depend on the location of the stress fracture. Most stress fractures will heal if you reduce your level of activity and wear protective footwear for two to four weeks. Your orthopaedist may recommend that you wear a stiff-soled shoe, a wooden-soled sandal, or a removable short leg fracture brace shoe. Athletes should switch to a sport that puts less stress on the foot and leg. Swimming and bicycle riding are good alternative activities.
Stress fractures in the fifth metatarsal bone (on the outer side of the foot) or in the navicular or talus bones take longer to heal, perhaps as long as six to eight weeks. Your orthopaedist may apply a cast to your foot or recommend that you use crutches until the bone heals. In some cases, you may need surgery so that the orthopaedist can insert a screw in the bone to ensure proper healing.
Preventing stress fractures
Because stress fractures that don't heal properly can develop into complete breaks of the bone and can become a chronic problem, it's better to prevent them in the first place. Here's what you can do:
* Maintain a healthy diet. Eat calcium-rich foods to help build bone strength.
* Use the proper equipment for your sport. Don't wear old or worn running shoes.
* Alternate activities. For example, you can alternate jogging with swimming or cycling.
* Slowly increase any new sports activity. Gradually increase time, speed and distance; a 10 percent increase per week is fine.
* If pain or swelling returns, stop the activity. Rest for a few days. If pain continues, see an orthopaedist.

Green could very well be out for the season and this would be another hit to our depth at running back.
