One week after surgery

Surgery went well... should be back at things tomorrow (although typing is still slow and exhausting). Docs say I can run now; sweet!

Percutaneous Cannulated Screw Fixation

chilling effects, education
PCSF scaphoid radiographs

Yeah, so, I have surgery on Tuesday to insert a titanium screw into my broken wrist.

More geeky details below.

(I just remembered that Stephen Colbert broke his wrist --- chipped his triquetrum --- last year... remember, he started his "Wrist Watch" campaign and began wearing his WristSTRONG bracelets.)

The decision to do surgery was a hard one to make... it took a ton of research and benefited from two parents that are physicians (one who did surgery rotations in residency). To recap, I broke the scaphoid bone in my wrist earlier this week. The break is clean and not displaced (read: there's no gap between the two halves of the broken bone); this means it could heal on its own with only a cast. Unfortunately, due to the blood flow going to that bone (only one side of the bone is supplied with blood), the bone heals slowly and I'd have to wear the cast for 12 weeks. Even then, it could get worse and still require surgery. Part of the decision to go with surgery had to do with the invasiveness of the procedure...

The procedure that my hand surgeon recommends is called percutaneous cannulated screw fixation, PCSF (of the left scaphoid). Using this procedure, my bone should be fully healed by September 2 (95% of grip strength should be back by November). This involves a small incision in the wrist and a guide wire is inserted to the base of the bone. A drill is used to drill a cannulated screw through the scaphoid (See Fig. 1 of Toby et al. 1997). When screwed into place, the screw creates compression forces that keep the sides of the bone in contact. This contact allows the blood vessels to regrow across the fracture and the for the bone to fill the fracture.

This is vastly superior to the old-school technique of "open reduction"... where the flesh of the skin is flayed to get access to the bone. Yikes.

The screw will remain in me for life... and will probably set off metal detectors. The bone grows over the end of the screw.

(Michelle's flying out to be with me next week, yay!)

EFF Pub Quiz

EFF Pub Quiz This past Thursday, EFF hosted a Pub Quiz event where teams were asked 8 rounds of questions related to cyberlaw. Our team, from the Berkeley Clinic, was called Notice and TAKEDOWN.

We tied for third place with the Stanford CIS/Fair Use Project Team. Team Google, with Derek Slater, Tim Wu and Harlan Yu, scored second and Keker & Van Nest made first place -- with heavyweights Joe Gratz and Mark Lemley. More pictures here:

One-handed, indefinitely

wtf?, berkeley, education, exercise

Ouch! I'm lucky I can type this at all; if only one-handed.

(I decided to type this once here instead of numerous times. So, if all you get from me is a URL in an email, know that my one hand is probably tired.)

While biking to Cal today I got hit by a Dodge Ram 2500 Truck. I didn't see him until it was too late; he didn't see me either. It was a big fucking truck. Long story short, I broke the scaphoid bone in my left wrist (non-dom). I will probably have to have surgery to insert a Ti screw.

I'm very lucky... and happy to spend more time on planet Earth with quality earthlings.

Anyway, I'm still trying to process this all... an can currently type with just one hand. (Try putting on your clothes with one hand. It's fraking hard. Now try tying your shoes!)

(And yes, I was wearing a helmet. That's the most asked question after, "Are you ok?". And yes, I'm ok.)

And a few words about the structure of the eye . Everyone " retina ". Especially often we hear it buy clomid online in the phrase " retinal detachment ." So what is the retina ? This - the front edge of the brain, the most distant from the brain part of the visual analyzer. The retina receives light first , processes and transforms light energy into irritation - a signal that encodes all the information about what the eye sees . The retina is very complex and in their structure and function . Its structure resembles the structure of the cerebral cortex. The shell of the retina is very thin - about 0.14 mm.
