Summary
Posterior full-endoscopic cervical discectomy (pFECD) effectively treats migrated cervical disc herniations (CDHs). Tailored bone resection, including partial pediculotomy, ensures safe and complete removal of disc fragments.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Posterior full-endoscopic cervical discectomy (pFECD) is a minimally invasive technique.
- Optimal working corridors and bone resection extent are crucial for treating highly migrated cervical disc herniations (CDHs).
- Individual tailoring is necessary based on disc migration direction and degree.
Purpose of the Study:
- To evaluate the safety and efficacy of pFECD with tailored bone resection for highly migrated CDHs.
- To demonstrate the technical modification of partial pediculotomy for cephalad and caudal disc migrations.
Main Methods:
- Two cases of highly migrated CDH were treated using pFECD.
- Case 1 involved caudal migration (C5/6) requiring partial pediculotomy.
- Case 2 involved cephalad migration (C6/7) treated with partial upper pediculectomy.
Main Results:
- Complete removal of migrated disc fragments was achieved in both cases.
- No neurological sequelae were observed post-operatively.
- Both cephalad and caudal migrated fragments were successfully addressed.
Conclusions:
- Partial cephalad and caudal pediculotomy is a safe and effective modification of pFECD.
- This tailored approach is suitable for managing significantly migrated CDHs.
- pFECD with individualized bone resection offers a viable treatment option.

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.

Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
