Dr.O, On 4/25/16, my 7 year old Morgan mare was diagnosed, through MRI, with a fracture of the medial wing of the right front coffin bone. She also has large side bones medial and laterally in both front feet which were diagnosed at the pre-purchase exam when she was four. The MRI showed no signs of abnormal sclerosis or edema within the wings of the coffin bones or side bones in the right lateral or left medial or lateral. This mare is/was used for showing English Pleasure and trots above level with or without shoes. The treatment instructions and recommendations are much the same as those described in your article. Bar shoe with large side clips and equipak, combined with prolonged stall rest with up to 10 minutes of hand walking daily. The shoe has been reset every 5-6 weeks. July 20 she had followup radiographs which showed some healing. November 1 she had another radiograph which showed significant filling of the fracture. The local vet thought she could now be turned out in a round pen for her exercise. My trainer and I both commented, based upon our experience with this mare,that she would probably do a lot of rearing,bucking,and running so we decided to continue with the hand walking until we see that the fracture is completely filled. The vet who has been doing the followup radiographs, recommended another set when she has her shoe reset which should be next week. If it appears to be healed would you recommend turning her out even though she will probably "tear around?" I hope to be able to show her again and am willing to wait as long as it takes. Thanks for your input, Jane

Hello Jane, Do we know a cause for the fracture? If any predisposing causes are corrected and the coffin bone is healed radiographically turn out in a small space is sensible. Perhaps you could begin with sedation with acepromazine to ease the horse into the situation. DrO
