Diagnosis - Heterotopic Ossification

Follow up from my last post for my hip challenged triker buds.

It's taking a little longer then planned to get back to pushing pedals. The anti-inflamitories have eased matters up a bit and taking it easy has almost gotten me back to normal...at least my version of normal. I'm starting physical therapy in a couple of days with my #1 PT, Custom Physical Therapy. I'll follow the PT up with some easy trik'n.

Final diagnosis...heterotopic ossification in the soft tissue of my right hip. Sorted details for heterotopic ossification here. Now that I'm returning to my former glory the right hip feels the same as it as for the last year. In the end it seems that I'm no worse off than before I stressed out my hip about 4 weeks ago. Again, it was not cycling related, whew.



The x-ray shows my right hip and the offending bits of calcium buildup just above the femur most likely due to inadequate irrigation of the area following hip replacement surgery. Thanks Dr. Yun for the souvenir.

  1. Hope your recovery is going better. I've been enjoying reading your posts the last couple years. I suspect like you one of the funniest parts of cycling is tuning and improving the hardware so it interfaces better with the rider providing a more comfortable ride or more efficient energy transmission. If changed components, replaced chain tubes with pulleys moved to higher pressure tires, I took a hacksaw to the control bars to lower the profile and make them more ergonomic and aerodynamic.

    That was all to my Expedition in the first year before i put it up on a trainer and bought my Road, I put all that learned into the initial purchase on the Road which I set up to contend with the rougher post winter conditions in New England, salt and debris on the streets and back roads, the suspension 1.75" tiers and seat pad deal with the potholes fallen branches and dirt rather nicely and I even added a 42T Wolftooth to the Read for climbing the more daunting roads and trails in my area. (Named the thing Tigger because its orange and black and has a very bouncy tail)

    And now I have three Catrikes , my fav being the last, a partially built 700 I've been customizing since last summer. S60 Carbon Rear, SL-k Carbon Cranks with Q-RingsT-Cycle Pulleys and KMC-SL Chain. I have a standard set of Catrike Velocity front wheels on the 700 but would like something racier. I have spoken with Dana at Bent up Cycles a few times (Maybe a few too manyas i have not pulled the trigger yet) about a custom Carbon wheel set they assemble at his shop, they recently changed the rims from 50mm to 38mm so I put the order on hold again... I am curious about your thoughts.

    1. I'm surprised Dana went with a 38mm rim. It limits your tire selection. The largest tire would probably be a 23/622. I'm very happy with the speed and comfort of a 28/622 Schwalbe One. I agree with you, experimenting with different components and setups is fun...but pricey. I'm currently thinking of popping on a ICE Suspended Sprint. I could use a little suspension for some of the rougher roads (Hwy 1). I would try and keep it reasonably fast and light by setting it up with a hard shell seat and similar tires and components as are on my 700. It's going to cost a few bucks but staying active and in shape while having fun is worth the investment.

    2. Sorry Mark, I believe its a 406 carbon fiber rim with a 38mm side profile depth vs the 50mm Depth. Hope that makes more sense. the advantage being stiffer rim with shorter spokes also a steeper angle on the spokes making it laterally stiffer.

      Can you tell me a Bit more about the advantages of the "One" over the Ultremo? or the Durano's?

      Ad for the suspension stuff... I have a few sneaky thoughts, I am going to see if Its going to be possible to adapt a set of cortices new front suspension from wheel mounts from the Dummont to my Road. Might take a few months to confirm if it will work and then getting them might be tricky. they are a tad taller which works well because I'd prefer a little more recline in my seating position.

      Aside from that you might try some more bulbous tires like the Marathon 1.75 or even 2" tires. Bring them to peak pressure you will be slower but the ride will soften up. Much cheeper then a whole new trike... not to mention I don't think I could go back to steel frames.

    3. Yeah...I don't know what I was thinking. I got numbers reversed in my head regarding tire width vs rim width and thought that's what you were talking about. As for the going with a deeper profile on the rim I agree with you. I would be more comfortable with a 50 vs a 38. 50mm looks cooler as well.
      Over the years I've tried big tires and little tires as well flatless tires at various pressures. In the end I like speed and have found a 28/622 rear tire pared with 23/406 front tires kept at the low end of the psi rating works good for me. It also goes in line with new studies that super skinny high pressure tires are actually a bit slower. I did a post back on August 8th, 2015 regarding tire size and pressure. http://bentupcyclingjournal.blogspot.com/2015/08/tire-pressure-revolution.html
      It is my understanding that the Ultremos are being phased out in favor of the Ones. They seem to hold up well and are fast tires. I get my tires from XXCycle in France (hard to beat their prices here in the States) so when they no longer stocked the Ultremos I went with the Ones and have not been disappointed.

    4. Cool I will modify my Amazon shopping cart then... I'll looking into your dealer too.

    5. Mark, Having Hub issues, what did you have to do to the chris king hubs to fit them to the catrike?

      Delete
    6. Dana at Bent up Cycles installed them for me. Dana shortened the inward facing part of the CK axle by cutting a small section off. By doing so the CK is the same width as the Catrike hub. He did it on a jig so the cut was precise.

    7. Dana never got back to me about the 50mm rims, so I think I am going to try and work with a local wheel builder out of Belmont Wheel Works. Getting the Hubs is still the tricky part.

      Delete
    8. Sorry to hear Dana didn't get back to you. And yes, the hubs can be bit tricky. But the CKs sure look good. Unless there's a CK hub out that works without tinkering with then the axle will have to be machined for a perfect fit.

    9. Could you post some close up photos of the mods made to the CK Hubs? On and off the trike, from the one photo I found It looks like about 1 CM is trimmed from the outer collar of the axle shaft trimming it down to the outside clamp. Did it require any trimming of the inside (Bike side) Portion of the shaft?

  2. I finally finished the Wheel build except for the Rotors there are some photos posted here....

    2. Thanks Just picked out the Rotors I want for it.. Three ore tasks then Ill have this trike done... Wind skirt for the Front end of the mesh seat, Replace the Steel Bolt and Nut on the Power Pulley with a Recessed Hollow Titanium shaft, and making a lighter headrest based on the Krispy Steve design. I might change the Badging on the trike too so something more color matching. With that I'll have the upgrading bug on the 700 out of my system.
