==== AP article follows ================= Jury Awards $5.6M in Screwdriver Case

50 minutes ago

HILO, Hawaii - A Circuit Court jury on Monday awarded $5.6 million to the family of a man who had the shaft of a screwdriver implanted into his spine by an orthopedic surgeon, the family's attorney announced.

Dr. Robert Ricketson had contended he acted properly when he operated on Arturo Iturralde in 2001 because two titanium rods he planned to attach to Iturralde's spine were discovered missing during the operation at Hilo Medical Center.

The stainless steel screwdriver snapped days later, and the then-73-year-old Iturralde had to have three more back surgeries as a result. He died two years later.

The jury determined Ricketson, 48, was negligent, and that the hospital was negligent for credentialing him and allowing him in the operating room, family attorney Mark S. Davis said.

Miles Takaaze, a spokesman for the Hawaii Health Systems Corp. which runs the state's 12 public hospitals, did not immediately return an after-hours call seeking comment.

Davis said earlier that Ricketson's medical license had been suspended in Oklahoma and Texas before he came to the Big Island.

Judge Glenn Hara will determine how the payment ? $2.2 million to compensate the family for medical expenses and damages and $3.4 million for punitive damages ? will be split between Ricketson and the hospital.

The jury suggested the hospital be found 35 percent at fault for compensatory damages, Davis said.

Davis had said that upon discovering the rods missing from a surgical kit, Ricketson used a hacksaw to cut off the screwdriver's shaft and inserted it into Iturralde to brace the spine. Unka George (George McDuffee)

That story doesn't sound true. Screwdrivers bend unless they are very hard. If that one was very hard the hacksaw would not have cut it.

Oh my God, what a hack. I'm still having trouble understanding why the "screw driver" broke. First off, get the usual image of a screw driver out of your mind. These drivers usually have a hex or Torx end on one side and a special driver configuration on the other that fits into a power driving tool. Similar to an electric hand drill.

The driver bits are usually made out either 440C, 17-4Ph, or Custom 455 Stainless, hardened to around 36-38 Rc. The main problem is that these aren't implant grade stainless steels. Infection and rejection would be inevitable. But the Titanium rod that was supposed to be there would have sheared under less of a load than the stainless driver bit would have (assuming the same diameter). Something else bad happened to cause that stainless shaft to break. The strength of the Stainless is probably two to three times that of implant grade Titanium which is usually Ti-6Al-4V ELI. I wonder if the spinal screws were improperly installed or if he only tied two of them together with the screw driver shaft instead of all four.

Either way this guy shouldn't be allowed to touch another patient.

Titanium and bone have a special affinity, which is why it is used for this sort of thing. Bone grows onto and around titanium (only) making the joint stronger than bone alone.

Greetings Rex, Bone will attatch to titanium and grow around it. But it's not the only metal bone will grow around. X-rays show bone growth around stainless plates in each of my arms. Apparently it doesn't stick. but it does indeed grow around it. Eric

True, but the part he replaced with the screw driver shaft is not implanted into the bone. Also 316L stainless is used for implants as well as other grades of stainless, often in these very components. I found more pictures of the x-rays and it looks as though he only put in one set of implants and one rod. Usually there are four implants and two rods. I'm thinking that's why it broke, one set isn't enough to stabilize the patients vertabrae. He must have been in serious pain up until his spinal cord got pinched.
