The indication for hip release is, of course, hip stiffness.

There are many causes of hip stiffness, such as lack of proper exercise after trauma, lack of proper exercise after hip replacement, hip stiffness due to osteophyte entrapment in the hip joint, and so on.

Hip release can be performed for each type of hip stiffness.

This surgery is a stiff joint caused by poor exercise after hip replacement.

Although he didn't care about this patient, Lu Cheng also knew that it must be after hip replacement, and the lack of correct exercise methods led to the adhesion of the muscles that had obvious boundaries in front of the femur, resulting in limited mobility of the hip joint.

This is the most likely cause, of course, it may also be a concomitant symptom, and it may also be that after hip arthroplasty, the pain management is not satisfactory, so the patient is reluctant to move, resulting in the adhesion of the muscular layers.

Of course, it may not be the adhesion of the muscle layer, or it may be the loss of the muscle space caused by scar hyperplasia, so the movement is limited.

Regardless of the cause, there is no accurate way to evaluate it before surgery, and it is necessary to explore it during the operation and then solve it accordingly.

This is a very basic operation, and it is very anatomical.

Lu Cheng was watching very seriously, his tongue kept licking his lips, and he wanted to have a feeling of going up to see it in person.

This operation is not big, although Professor Min did not walk out of the operating room, he did not go on stage.

"Xiao Zhu Zhu, you can do this operation, as long as the anatomy is done well, it is not difficult, it is difficult in postoperative analgesia management and the patient's recovery. If the recovery is not good, there is a possibility that it will stiffen again. Professor Min found a footstool, laid out a sterile sheet, and sat down against the wall and said to Zhu Queguang.

Suzaku said, "Okay, Professor Min." Then this operation, Brother Da You, and Brother Xiaocheng are three, and it is enough. ”

Hearing this, Lin You also hurriedly said: "That Brother Zhi, Brother Da Hui, you all have to rest first for this operation, you don't need so many people to go up, and you will have to rely on you to support the sorghum later." ”

When they heard this, they did not refuse.

Hip release surgery is just a minor operation, there are no special techniques to learn, they can be lazy, and they enjoy it.

But this kind of minor surgery is a particularly good practice for Lu Cheng.

Obviously, it can be seen that Professor Min, Lin You, and even Zhu Queguang are taking the initiative to find a chance for Lu Cheng, if they still don't agree, it will be too uninteresting.

Lu Cheng was immediately overjoyed, knowing that he had almost gotten started, he came again.

That's the benefit of going to the operating room.

Wash your hands and spread the towels, naturally belong to Lu Cheng, and raise your feet to Lin You.

After Zhu Queguang came to the stage and cut the skin along the scar of the last hip replacement operation, he suddenly raised his head and asked Lu Cheng: "Xiaocheng, tell me about it, what structures will be encountered in this release operation?"

Is this a test of me?

Lu Cheng glanced at the location of the incision and replied: "Brother Queguang, this is the lateral incision of the hip joint, from the outside to the inside, divided into vertical planes of the surgical field: skin, superficial fascia, gluteus maximus, gluteus medius, and gluteus minimus. piriformis muscle, which may also encounter the inferior diaphragm muscle. ”

"On both sides of the surgical field, tensor fascia lata, quadriceps may be encountered. ”

"When doing hip release, the main thing is to see if there is a large amount of scar hyperplasia in the original surgical approach and whether it needs to be released. ”

Then blunt release the quadriceps anterior muscle. ”

Suzaku listened, thought about it, and asked again: "Then what if you cut the nerve?"

Lin You suddenly looked at Lu Cheng, and Lu Cheng smiled and said, "The largest bone nerve and sciatic nerve are located anteriorly and posteriorly respectively, and they are cut in according to the lateral approach. ”

"At most, it will only cut to the lateral cutaneous branch of the iliohypogastric nerve and the anterior and posterior branches of the lateral femoral cutaneous nerve, and the damage to this nerve terminal will only cause local numbness at most, and it will be fine after a while. ”

"I don't think it's a big problem. ”

Suzaku thought about it, smiled, put down the round knife, and said to Professor Min: "Professor Min, I think this Xiaocheng can practice his hands, do you think?"

Professor Min asked in a whisper, "Xiaocheng, if you can name the innervation area of the iliohypogastric nerve and the lateral femoral cutaneous nerve, you can do this surgery." ”

Of course, Lu Cheng's heart fluttered and jumped, in fact, doing this operation has nothing to do with the distribution area of these two nerves, but Professor Min is studying his basic anatomical knowledge.

The iliohypogastric nerve is derived from the abdomen and does not originate from orthopedic anatomy.

But Lu Chengke remembers it clearly: "The iliohypogastric nerve is distributed in the skin above the pubic symphysis in the abdomen, sending out the lateral cutaneous branches, which are distributed in the upper skin of the lateral femor. ”

"The anterior and posterior branches of the lateral femoral cutaneous nerve, which innervate the anterior and posterior skin of the lateral femoral respectively, are probably out of shape, and the possibility of variation cannot be ruled out. ”

"Huh. ”

Professor Min smiled again, and suddenly he asked Zhu Queguang and Lin You, "Xiao Queque, Xiao You, Xiao Cheng said this distribution, do you two know?"

Lin You and Zhu Queguang, who asked this, blushed.

To be honest, if Lu Cheng hadn't deliberately mentioned it, who would have paid attention to the distribution and innervation of this epidermal nerve.

It's basically useless, and if it's broken, it's broken.

The epidermal nerves of the whole body are distributed everywhere, otherwise how can you feel pain, where does it come from, and is it meaningful?

Even some professors don't necessarily pay attention.

The ghost knows where this Lu Cheng remembered it from.

Of course, they also nodded honestly.

He replied with a smile in his mouth: "Professor Min, we reviewed, and we usually don't pay much attention to it." ”

Professor Min naturally took over the words: "Since you don't know, then give the position of the main knife to someone who knows." ”

Then he lay down and closed his eyes in peace.

It is also advantageous to be able to have such a deep foundation and do this kind of relaxation. Even if you remember this kind of edge and corner, then the deeper and larger anatomical structure inside is naturally very clear.

Lin You and Suzaku Light originally had this meaning, so they let it out.

It's just this scene that made those nurses and Deng Zhi and others who were resting a little confused.

What's going on?

Professor Min asked a question, is that a question?

What Lu Cheng answered, is he called a normal thing?

Iliohypogastric nerve?

Isn't this the anatomical knowledge of general surgery?

"Teacher, bring a bone peel, thank you. Just when the nurse who was washing her hands was still stunned, Lu Cheng had already begun to call the equipment.

The nurse who washed her hands immediately replied, "Oh, give it!"

Lu Cheng continued to instruct: "Take two small bends, Master, Brother Finch, please help me pull it, I want to ......"
