The Jones fx is an intersting animal. I am a physical therapist, have treated a number of these. The fracture region at times has poor blood flow and does not heel well with conservative treatment (walking boot, limited weightbearing with use of crutches). If conservative methods fail, the orthopedic fixates the fx with a screw which is usually effective. I have worked with numerous athletes who heal well with either method and return to sports. Of course these were not the Kevin Durants of the world! The foot injuries that we have seen over the years in the NBA that don't respond well have been the huge guys: Muresan, Oden, Ming, the Cavelier center whose name escapes me...they are plodders with massive weight that really hammer their feet. The 5th metatarsal is the spot for the Jones fx, and this bone is not a major weight bearing region (base of the pinky toe), and is not as major of an injury as say a mid-foot fracture/sprain or heel. The Jones fracture can be caused in conjuncture with an inversion ankle sprain (inward excessive ankle torsion/rolling) vs an impact or load bearing incident. The tendons attaching to the bony region can overpower the bone via a forceful stretch during an ankle sprain and cause a Jones fracture. Not sure how his injury occurred, but hopefully with the correct treatment and precautions he will be good to go soon. Always a risk with returning to action too soon with foot injuries, but I imagine he has consulted the experts!
