THIS STUDENT had his first hip replacement aged TWENTY, and by the age of TWENTY-FOUR he had his fourth hip replacement as a result of a rare bone disorder which ATE AWAY at his hips.

Graduate student, Aaron Blocker (26) from Mississippi, USA, was diagnosed with Crohnâs disease in 2009 and then diagnosed with avascular necrosis in both hips in 2010, meaning the bones were gradually dying without Aaron knowing.

In September 2012, at the age of just 20, Aaron was told that he would need major surgery involving replacing both of his hips due to his deteriorating condition. The pain from just walking a few steps became too difficult and surgery was the only option.
Aaron has been diagnosed with hypophosphatasia, a rare disorder that affects the development of bones which caused the necrosis of the hips. The disease affects less than 1,000 patients across the USA, making the diagnosis very difficult.

While in the middle of studying for his masterâs degree at the age of 24, Aaron underwent his fourth hip surgery in as many years. The initial hip replacement was supposed to last between 15 and 20 years, but at the time doctors werenât aware of Aaronâs rare bone disease which ate away at his hips.
Despite spending a lot of time on crutches and facing limitations every day due to his condition, Aaron remains positive and hopes to redefine the idea of a ânormalâ life to show others that itâs still possible to accomplish anything they desire.

âI was diagnosed with avascular necrosis of both hips in my second year of university in 2010, and then last year I was diagnosed with an ultra-rare genetic bone disease called hypophosphatasia,â said Aaron.
âHypophosphatasia contributed to me developing avascular necrosis which meant I needed so many hip replacements.

âBefore surgery I had horrible pain, couldnât walk well. I was on crutches and wore leg braces on and until the surgery.

âI was 20 years old and told I needed my hips replaced, so major surgery was needed. Itâs a surgery that people typically donât need until much later in life, so I was devastated.

âMy first hip replacement was September 2012 and I was in the hospital for five days after. The surgery really helped â I didnât realise how bad they had become until I could barely walk and realised it needed replacing.
âThe next hip replacement was December 2012, but I ended up staying in hospital for 10 days because I had an infection in my incision.

âHip replacements generally donât last terribly long. I was told my initial replacements might last 15-20 years, but back then we didnât know I had a rare bone disease, so they only lasted for three years, but no one knew why.
âWhen my hip replacements failed, and I was told that I needed both hips replaced again, after only three and a half years I was even more devastated because I was only 24 years of age â I knew I needed it because of the problems I had, but it was tough.

âI sat in my car after my appointment and cried to myself. Since I was only 24 when I had my second round of replacements, even if I get 20 years out of them, I would still need them replaced again later in life.
âWith my bones being so bad, thereâs always a chance I may need surgery here and there. Itâs just a fact of living with my diseases.

âGetting the hypophosphatasia diagnosis was a bit of relief in hindsight honestly. I have had bone problems since I was born so the diagnosis, although it was scary, it was a relief to us all to finally understand the issue.â
Aaron wants to encourage people to be positive despite what their condition is as he refuses to be beaten by his bone disease.

The rare disease has an impact on Aaron in his daily life, from causing pain to stopping him from being able to run. However, he has a level of pride from what he has managed to accomplish so far, including starting a family with his wife, Emily, and hoping to work in microbiology research.
âI have always tried to live in spite of my disease and show that even though I have faced more health challenges in my 26 years of life than most people will in their entire life, I can still pursue my dreams and accomplish a lot,â said Aaron.

âI want to be honest and open by telling people that itâs not easy. I have to put in so much extra work to work around my disease and to know my limits.
âSo many people are shocked when they learn that I have had hip replacements so young. I have had some people not even believe me until I showed them proof.

âI think the hardest part, outside of the surgery, is the physical limitations I face because of it. My rare disease impacts my energy levels, causes pain and limitations, but having four hip replacements means you can never go back to ânormalâ.
âI canât run, canât squat, and I have muscle problems in my legs from surgery, so itâs been tough. I still have a normal life and I can do a lot of stuff, but I do have limitations which will always be present.

âI am proud of what I have accomplished with my schooling and also of the advocacy work I do as a patient.â
