Our nearly 12 y.o. house bun Tiny mysteriously broke her femur in January. A closed fracture, not the bone piercing thru the skin.
Diagnosed by radiograph. I got her to the clinic immediately as an ER appt. when I saw her leg was not right. Vet gave 4 options after the xray: surgery, amputation, euthanasia, or _ 4) the option I choose - some wait 'n' see time in a Small Confined Space to allow bone remodeling to occur. Tiny would not have done well with surgical intervention, especially at her age. Not to mention the $3K costs and overnight recovery, et al.
Tiny's fx'd femur healed! The bone remodeled in the 2-3 months I kept her confined on soft bath mat bedding in a 36_inch L x 24 W dog kennel crate. All one level, no jumping or hopping into a litter pan to upset or hamper bone remodeling. Her leg is not perfectly aligned comparing her leg to all our sanctuary crew members, but she can periscope and hop in her ex-pen. One of the vets at the clinic implying "no way" would her leg heal without the surgery or amputation still bothers me to this day. I was happy to do the course the other 2 DVMs felt was worth a try.
I consulted with others. Listened to adopters who had bunnies heal with confinement, plenty of suggested pain meds. Always follow-up with a rabbit savvy DVM or xrays to determine the best course for healing. Tiny's fx'd femur didn't require a PTS.
I've broken bones so I'm aware of the pain!
