I have a current problem with my right hand be partly paralized ie very minimal movement of my fingers and wrist. The doctor said I must have slept on it and damaged the nerves. I should have told him I race a high-lateral-g race car. My physio chicky has other ideas after viewing my vids. So I thought maybe a hans devise will restrict my head movements as my necks is always sore after a full day going roundies and this is where the nerves travel from.

My currect Bell Vortex Helmet doesn't have hans posts and here I'm thinking I'm going to get reamed hard up the tucker shoot,,,getting some pro to install them or worse having to buy a new helmet,,,I e-mailed Revolution Racegear and here's what I received in reply.

Seems you can actually do it yourself!!!. Now I have no idea if this is legal,,,but I'll be doing it anyway.

Just thought I would share this info with you all.

As far as I am aware, if the helmet is compatible with the HANS system ie, the manufacturer makes the same model with the holes already in place, then for anything up to FIA level events it is legal to retrofit the posts by drilling as shown.

Hey Neily - I think a HANS is a great investment but as Benny said it's probably not going to help with your movement issue. They are pretty much designed to stop your head whipping forward in a crash and not restrict your movement otherwise. Though some people do complain about it being restrictive I've never found it to be.

I think you'd be better off trying a neck collar like this first http://www.soloracer.com/pyrocollar.html

Probably more suitable for support and restricting movement and about a tenth of the price of the HANS!

And btw NO chance we'll be letting you drill holes in your helmet for posts sunshine :rolleyes:

I use one of these. Seems to work well and saves my neck from whipping around. I actually got a faster lap time when I didnt have to concentrate on keeping head upright.

It fits reasonably tight between my helmet and my shoulders. So my head movement side to side is very well damped. Fairly comfortable actually. I can still look side to side, but can let a load off and allow the helmet to sit on it. A lighter helmet might have helped but I cant afford a carbon one.

They are only about $110

ive seen one installed with a cordless drill......it worked but just seemed wrong when they were doing it.

The Hans device should helps a little if you have mil to mod cervical spondylosis.

Having little motor function sounds a bit more serious than moderate cervical spondylosis.

Have you had any CT scan or MRI scan?

I would recommend a CT guided cortisone injection, Glucosamine and use as much neck protection as possible if you wish to continue motorsport;

-good helmet

-Leatte brace/hans device

-race seat with neck support

-window net

Its a bit of a grey area really, ive been told drilling into a helmet would void it. Yet as you say HANS say you can do it yourself.

Interestingly enough when I got mine from BSMSport I said can you fit it and they said clearly NO! but when i said my helmet already had the holes from the factory they said oh yeh easy.

If you did go this way I would strongly suggest a sliding tether and probably quick release posts. I think I am going to get quick release since I am in and out of the car often and its a pain in the ass trying to take it all off in the cabin.

You can get this sort of dysfunction with mild or non-existent spondylosis as functional changes account for the vast majority of symptoms. However, the likelihood of some spondylosis/degenerative change/osteoarthritic change/wear and tear is higher as we get older. Even with degenerative changes most symptoms start suddenly which tells you something else has changed more recently which triggers the symptoms.

Issues with the hand could be anything from elbow/wrist/hand issue right through to thoracic outlet syndrome to spinal nerve irritation.

Plain x-ray is the minimum.

Glucosamine has very little evidence for helping necks, although there is little harm in using it for helping articular cartilage generally (particularly knees).

I would be having a really good look at joint movement in the lower neck and improving this area (chiro, physio etc) and secondly the thoracic outlet, then the carpal tunnel, then wrist/elbow muscles. There is no chance anyone would be sticking cortisone in me until other conservative treatment was exhausted.

Geeezz I did not realise there is someone on here who takes free medical advice with more than a grain of salt.

Statistically 90% of the typical cases will resolves in 6-9 weeks anyway. Neil symptoms sound more serious than typical.

Lets discuss anyway....

True, however common things happen commonly.

From the very brief history and lack of any traumatic injury place spondylosis highest on the list of differential diagnoses.

Other causes are A-Z.

However, the likelihood of some spondylosis/degenerative change/osteoarthritic change/wear and tear is higher as we get older.

70+ % on XR for over 40 year old

Even with degenerative changes most symptoms start suddenly which tells you something else has changed more recently which triggers the symptoms.

Yes, common cause is that he slept wrong (or slept with it as giant suggested) but doesn't quite exclude A-Z.

Issues with the hand could be anything from elbow/wrist/hand issue right through to thoracic outlet syndrome to spinal nerve irritation.

The chance of a lesion involving all 3 (radial, median and ulnar) nerves somewhere in the forarm or the nerves around the arm (without any effect on the bicep or triceps) causing partial paralysis of the hand are remote. Brachial plexus lesion is possible but often gradual and almost all of my TOS diagnosese revolved with appropriate cervical management.

Most likely diagnosis is multilevel cervical spondylosis with osteophytes especially around C6/7 to T1 with impingement of C7, C8 and possibly T1 nerve roots.

This still doesnt change the proability of A-Z lol

Plain x-ray is the minimum.

70+% of people over 40 wil have cervical spondylosis

Cervical Xray has poor sensitivity/specificity.

It's a waste of time and money in my trade and in this case.

I would advise the patient to save money, wait for a few more week and if he/she doesnt get better then get an MRI scan...if there isn't any red flag on further history or examination

Glucosamine has very little evidence for helping necks, although there is little harm in using it for helping articular cartilage generally (particularly knees).

That's because of poor study techniques not because the medication doesn't work for those synovial joints.

I would be having a really good look at joint movement in the lower neck and improving this area (chiro, physio etc) and secondly the thoracic outlet, then the carpal tunnel, then wrist/elbow muscles. There is no chance anyone would be sticking cortisone in me until other conservative treatment was exhausted.

That is true but not everyone race a cool car like Neil and still like to race even with this amount of problem.

In all seriousness, I agree with you invasive treatment is the last resort for some diagnosis but is the first line for some diagnosis according to the current literature (and my experience).

My advices for long term prevention still stand.

Remember this diagnosis is only from an incomplete history. Obviously the working diagnoses will change as one get more information from examination and investigations....it's like playing Texas Holem lol...just one is more fun than the other :D

Bloody hell boy's I didn't expect all the medical stuff. Thank you very very much indeed.

I'm off to see my doctor again on Wednesday and to the hospital as they are going to make me a splint and as usual physio everyday.One of my problems is I'm over working every other muscle in my body to compensate which has made me sore as shit,,,tired,,,irratable,,,oh and grumpy.

I think I'll print this out and take it with me.

Oh I didn't mention I'm racing again in 4 weeks,,,someone better fix me fast!!!. Oran Park GP,,,will be the last time I run on it in anger.

Thanks again for the info,,,I didn't expect it.

Neil.

I wasn't trying to take start anything but I do work on these daily and I am certainly advocating conservative care prior to more invasive care.

You are going to find we have 10x more common ground than differences of opinion but what I say stands most of it is factual in science and a little of it is hard won opinion just like yours :P

I like glucosamine just fine just in case you think I am naysayer.

I hope Neil gets some benefit out of this as a diversity of opinion (and lets face it you are saying potato and I am saying potaato) should help him get the best outcome and a speedy recovery.

Bloody hell boy's I didn't expect all the medical stuff. Thank you very very much indeed.

Sorry Neil, it was meant to be short and simple but some how it became a medical blurb :)

Your GP won't be able to send you for an MRI unless he has some good connection, only specialist can refer for MRI scan.

The guideline will dictate that XR is the first line of investigation in your case and then if xr shows cervical spondylosis then MRI scan.

That is because these guideline predate the abundance of MRI machines. Nowaday, MRI machines are everywhere and often with empty lists. So you can get them if your GP has the right connection.

The evidence in the literature is that 70+% of people over 40 will have cervical spondylosis in XR, so 70% of people will waste their time and money with the XR. XR is around $100 and MRI scan can be done for $170-800+ (if you know where to go).

You can not and should not get a cortisone infiltration (neck) until you have a MRI scan.

The infiltration is "CAT machine assisted"...ie performed by a radiologist with the help of a CAT machine.

You will get more benefit from an experienced radiologist.

It's all good mate. I know where you are coming from.

I can't say I treat this daily but I see this 5 days per week :)

I never treat any of them, I only assist them in making the right decision for their medical issue.

I am in QLD so I can't offer any help with your issue Neil.

I do hope that I am wrong and you are in the 90% of typical cases that do get better though.

If you have any query, please feel free to shoot me a pm.

Good luck Neil

Might be an image somewhere of Peter Saunderson's Radical, a handy steerer.....probably Sports 1300 Qld newsletter, he has a support structure off the ROPS he's been using for 5 odd years to assist with lateral G which might give some ideas.....not sure I'd want to have a bingle with it though.

Best practice I've seen was the Audi LMP (I think), with a removeable composite support up the cockpit center line a la open wheel norms from a few years ago - Mulsannes corner might be fruitful in that pursuit.

Hope it's not spondylosis, do find the affliction helpful for spotting dropped money though!

Well I got really lucky today and got this brace made and thanks to Australia's great health care system I didn't have to pay for it.

I have an appointment tomorrow with a neurosurgeon,,,one days notice and got someones's cancelled booking. Lucky for me my doctor owns a BMW. Somehow I think I'll get pay back.

    • I'm seeing torque specs all over the place for the OUTER tie rod, but none for the INNER tie rod, where it connects to the steering rack. Even in videos, people are just tightening em up as much as they can with a wrench and that's it. Anything tightened down without torque makes me nervous. Anyone know what the spec is for it?
    • Hope you had a great time here in our tiny country.   The JDM scene we have here is quite small, it's mostly BMW, Volkswagen with burble tunes haha. But the few JDM cars we do have in the scene are pretty nice. Some of my friends drive cool s14's too. Both built engines, red one makes abt 500, blue one abt 400 i think?
    • Ye good idea , would have never thought of something like that. Might aswell do it to every pulley and the balancer while I’m there 
    • Use an LS1 or similar, via kit like Frenchy's. But.... It's probably not the alternator. It sounds like belt squeal, which would be because the pulleys are glazed. Rub every groove on the pulleys with 120 grit paper. Report back. Oh, and new belts afterwards too. The old new ones will be shitted up already.
    • Hello all I have 2 r34 sedans , one turbo one na, only recently aquired the na 34.  Man what is with these things.... My turbo 34 started sounding like a super charger, it was screaming at anything above 4000rpm , I took the alternator apart and replaced the front bearing which is the only one I think you can access and it did not fix the issue so presumably the bearing in the rear of the alternator is gone. ( diagnosed it was the alternator by taking off the aux belts one by one to figure out which pulley or bearing it was )  My friend gave me one he had lying around, Installed it , it did not squeal for maybe 500kms and now its started to squeal again briefly on startup  Recently got an na r34 and I replaced the timing belt, water pump + all the auxillirary belts. Runs amazing but it suddenly developed the same squeaking problem but significantly worse, Ive had my neighbour come down screaming at me because it was waking her up everytime I moved the car. It takes a good 2 minutes before it quietens down.  Im yet to diagnose where its coming from but im fairly sure its coming from the alternator aswell. My question isnt about how to fix it but rather where can you get a new alternator for an rb25 neo??? Ive searched everywhere but I havent been able to find a direct fit oem type replacement thats not genuine. All the automotive stores sell an oex one - BXA035 - which I picked up for cheap through a friend with staff discount , got it home only to find the connector is completelty different.... As far as im aware bxa035 is for rb20/30's and after a bit of figuring out the bxa035 has an ev14 type connector, which is tiny compared to the rb25 connector. I actually had an ev14 connector lying around which I was considering just replacing the bigger plug with to get the alternator working but the bxa035 is rated for 70amp vs the rb25 alternators are 90amp ( or so ive been told ? ) That paired along with the fact im about to install an amp + sub in the back and I have the stock sized small battery Im not sure itll do the job unless anyone has another opinion?  I know and have seen all the websites selling the ls1 alternator conversion kit but I am not going down that route, nor do I have the money to. Hopefully I can figure out how to get 2 brand new alternators for both cars. I would buy second hand which there seems to be many of but considering how common this seems to be im sure If I installed a second hand one it would start squealing in no time  Or even better if anyone knows how to fix the issue directly with the alternator itself... Any input appreciated Thank you     Link for bxa035 connector picture
