Chapter 194: Chapter 0183 Calm Professor Ye_3
“Alright! Reopen the femoral tunnel!” Professor Ye puts down the screwdriver, flexing his wrist.
“Still double-strand?” Director Guan asked.
Continuing with the double-strand would be very difficult, three problems lay in front of them.
One issue was that the four screws occupied the space within the distal femoral condyle tissue, they would likely obstruct the opening of the tunnel.
Another issue was that all three bone fragments had been repositioned, but there were several fracture lines, opening the tunnel to these lines wasn’t ideal.
A third issue was that the hanging metal plate required a particular cortical thickness to support it, and suitable areas for this were now scarce.
“Of course–” Professor Ye confirmed without hesitation.
If they changed to single-strand reconstruction, the surgery results would be compromised. This was a professional athlete. They were seeking high-quality surgery from him, he could not give in on the quality of the operation.
His professional ethos would not allow it, and for the sake of his reputation, he could not either.
Exposure! Another exposure with a C-arm X-Ray machine, to view the positioning of the screws, preparing to avoid them when opening the tunnel.
“Guide pin! Open the femoral tunnel!”
Professor Ye extended the guide pin from the lateral opening, estimating the positioning.
He tried several times, shaking his head, it wouldn’t do. The point was not within the safe zone. The commencement point had to be within the safe zone. Otherwise, there wouldn’t be enough cortical thickness to suspend the ligament, which will easily tear the cortex.
He tried other angles, from straight to extremely flexed, all to no avail.
Not from the lateral opening, he punctured the skin from other positions and tried to insert the pin. Professor Ye tried almost all the plausible spots, but it still didn’t work.
The optimal position for this tunnel presently only has one direction, no room for adjustment. This direction explicitly is a blind spot, excessively complex.
It seemed they could only penetrate from the outside to the inside using the wall sniping technique. Last time the sniping target was a circle. Now the goal was a point, the difficulty level escalated.
What a day it was today, witnessing one of the top professionals in the country performing surgery like a magic trick, wall sniping, moreover, sniping at a point. This was a divine operation.
All observers of the surgery were experts, nobody dared breathe as they awaited Professor Ye’s stellar performance, making the operating room profoundly quiet, even the patrolling nurses were treading lightly.
Professor Ye inserted a ruler in, and measured the distal femoral condyle several times under a magnifying glass, planning out several lines, and using the intersecting lines to find the anatomical center of the ligament footprints. He then uses an electric plasma knife to burn a dot at that point.
Song Zimo didn’t hurry anything. Yang Ping didn’t make a return call either. They watched as Professor Ye proceeded with his entire operation. It was a top-tier performance in the country.
Professor Ye steadily held an electric drill, without the slightest shaking. This was a drilling technique trained strictly. The guide pin leaning against the cortex of the femoral condyle, appropriately placed, with absolutely no shaking or movement in his hands, extremely stable.
After adjusting the guide pin’s position and direction many times and repeatedly observing, Professor Ye finally pulled the trigger.
“Swish!” The guide pin was driven in. The position where it came out was around 5 mm away from the point, meaning it deviated by about 5mm. If it were someone else, they would probably think they were already successful and could proceed with opening the tunnel.
But he was of national first-class level. How could he accept a score of 80 points? He was aiming for a full 100 points.
The guide pin was pulled out and tried again. This time it was closer, the error reduced to about 3mm.
Further away this time, approximately a 7mm deviation.
