Injury or birth defect

[zx4g]

Hi all, had a vet appointment today. My 10 year old male star has been loosing weight and not been himself recently so I took him to our specialist vet. His exam was uneventful until the vet poked his finger in to the rear leg area to get his head out of the shell to examin him. After this whilst preparing an anti -inflammatory injection I noticed fresh blood from his rear leg area. On closer inspection the skin has detached from the Supracaudal? area. He is booked in for an operation to reattach the flesh using holes in his shell and sutures/skin glue to reattach. I wondered if anyone has experienced this and can offer advise or even an explanation of why this could have happened. Many thanks
