Corin Group Introduces Vertical machining centre to reduce lead times

Medical implants and instrumentation manufacturer has introduced 'lean' cell-structured machining systems - including high speed machining - to reduce overall manufacturing lead times

Medical implants and instrumentation manufacturer, the Corin Group, has introduced lean, cellular production techniques, which have transformed individual component machining times, as well as overall lead times. Newly-established routines have also streamlined production through reduced work handling and separate set-ups.

In addition, investment in another area has eliminated costly outsourced machining operations and allowed the company to take full control over its processes.

By establishing cell machining incorporating a Fanuc Alpha T21E high speed, 24,000 rev/min vertical machining centre (VMC), has, for example, been able to demolish lead times on hip replacement 'cups' from three days down to just one day.

Also, Corin invesed in two Fanuc Alpha wire EDM machines, to bring back in-house previously sub-contracted wire edm work.

Production manager, Trevor Buggins, at Corin explained that the Group's global reputation had been built around a policy of continual improvement.

It impacts every department of the 200 plus-employee company, which in more recent times, has attracted increased business from countries such as Japan, North America, Turkey and Venezuela.

Corin produces a wide range of products for the medical sector, hip, knee, ligament and spinal replacement items, as well as 'instrumentation packs' that provide surgeons with a complete set of tools for the appropriate task.

The company processes stainless steel, titanium and cobalt chrome alloys, for example, in various quantities to meet its growing forward order book and stock demands.

A 'flagship' product, the Cormet Hip Resurfacing system, combines the principles of conservative arthroplasty with metal-on-metal bearing technology to provide a solution for patients with osteoarthritis or rheumatoid arthritis.

It is in producing the components for Cormet that the Fanuc Alpha T21E VMC has been used to impressive effect.

Groin Pain seems to be a post-op problem for many people with hip resurfacing. Listed below are a selection of posts by people about their groin pain and what they have done to solve the problem.

But, if it's any help, my right hip took 18 months to settle down and 2 years before it stopped giving me trouble after a prolonged and/or intense workout. The trouble was a painful groin/front thigh which my surgeon diagnosed as bursitis. The workouts which caused trouble were anything involving lifting the thigh forward such as running or walking. It's fine now and causes me no trouble at all.

One thing that helps me to avoid a groin pain upon knee lifts, knee adduction & leg lifts is to first tighten my core, stretch out (lengthen the space between' the femur and the hip joint by pulling the femur out and lifting up at the hip' to the top of your head, thus creating plenty of room for making the movement.

I am now at the end of 8 weeks post surgery and I still have a' significant amount of pain in'  my thigh, groin, back of thigh and knee. This is at rest as well' as walking - even more at rest'  and during and after sitting.

Sandi, This is a topic that we revisit from time to time.' Inflammation of the tendons, tendonitis, is one manifestation of' faulty prostaglandin bioactivity associated with inflammatory' precursors such as tobacco, alcohol, analgesics, and omega-6 fatty' acids. Not to mention deficiency of omega-3 fatty acids, vitamins,' minerals and circulation thereof. Get the circulation going with' calf contraction, quad contraction, glut contraction, in that order' while lying supine, 10x for about 4 seconds each, to recharge the' blood flow from the ground up, about 6x per day. And don't worry.' Worry adds to inflammation by its own variety of toxic' neurochemicals. You'll be fine, give it time.

As of late, I've been having lots of ache at top of my quad muscle and inner groin pain.  My PT says my glutes are very weak , but I at present can't tolerate to do the exercises needed to strengthen.

I started with a new pain two days ago that is in my groin but towards  the back of my leg. It is worse when I have to extend that leg or stretch that leg. Feels sort of like a tingle but worse, stops me in my tracks. Sometimes I think it feels muscular but other times I feel like it is in the bone. I've been great up to this point so I'm concerned. Anyone else know what I'm describing? Any advice?

I'm six months post-op and still occasionally experience what I call "growing pains." Not only are your muscles recovering from the surgery, but also from years of not working fully (atrophy due to loss of mobility), regrowing those muscles (hypertrophy), and unlearning those bad habits we developed to compensate for our hips (e.g. one-legged squats to pick stuff up, limping, etc.). There's a lot of growing and retraining going on. So, it's like when we were kids - we have growing pains again! :)
