Competitive swimmer with scaphoid fracture. any tips to quickly recover?

Maintain cardio: Unfortunately, these fractures are notorius for requiring a cast/ surgery.I would suggest that you focus on your cardio by cross training w/ a stationary bike or possibly an elliptical (low risk of falling). - note: a surgical incision may even delay these options. Speak with your physician for specific recommendations/ restrictions. http://orthoinfo.aaos.org/topic.cfm?topic=a00012.

Internal Fixation: The fastest recovery from a scaphoid fracture will come from getting the bone to heal as quickly as possible. If cast treatment is chosen then using a cast which provides adequate fixation for your fracture is needed. Percutaneous fixation can return a patient to sports more quickly ( see http://www.Youtube.Com/watch?V=gqeygwpnbdg ). Bone growth stimulators may help speed healing.

Scaphoid: As per dr gutow, orif with screw fixation, bone stim, possible laser therapy, purified omega amd good duet/rest can help.
