A number of operations at the Royal Glamorgan Hospital in Llantrisant have been cancelled because of a shortage of junior doctors.
Cwm Taf Health Board says it's a temporary measure and it's apologising to anyone who's affected.
The hospital has been left with staff shortages after failing to recruit enough trainee doctors.
The Health Board said the shortage has meant it has had to cancel a number of operations in orthopaedics due to take place in the summer months.
The health trust which runs the Royal Glamorgan says it has had to cancel a number of operations in orthopaedics because of a shortage in trainee doctors and has offered its apologies to those efffected.
But they're not alone - all over the country, hospitals are facing the same problem.
Last month it was announced that acute medical serves at hospitals in Neath Port Talbot would have to end because of a lack of doctors.
