Bone Structure01:55

Bone Structure

51.9K
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Bone Remodeling01:40

Bone Remodeling

40.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Compact Bone01:27

Compact Bone

16.8K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Bone Disorders01:29

Bone Disorders

5.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

The Hyoid Bone01:12

The Hyoid Bone

5.3K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Spongy Bone01:09

Spongy Bone

8.1K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Summary

Ultrasonic bone scalpel (UBS) offers a safer, faster, and more effective approach to anterior cervical corpectomy and fusion (ACCF). This technique minimizes blood loss and reduces the risk of dural tears compared to traditional surgical methods.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Surgical Technology

Background:

  • Anterior cervical corpectomy and fusion (ACCF) is a complex spinal procedure.
  • Conventional instruments (high-speed burr, kerrison rongeurs) are linked to significant complication risks, including hemorrhage and incidental durotomy.
  • Minimizing adverse events in ACCF is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate the efficacy and safety of using an ultrasonic bone scalpel (UBS) in cervical corpectomy.
  • To compare the complication rates of UBS with conventional surgical instruments in ACCF procedures.

Main Methods:

  • A retrospective study analyzed data from 101 patients undergoing cervical corpectomy with UBS.
  • Data collected included total surgical duration, corpectomy time, estimated blood loss, and incidence of dural tears.
  • Patient data spanned from December 2014 to December 2016.

Main Results:

  • Single-level ACCF averaged 59.36 ± 13.21 minutes; double-level averaged 92.74 ± 21.04 minutes.
  • Estimated blood loss was 52.07 ± 29.86 ml for single-level and 73.22 ± 41.64 ml for double-level procedures.
  • A low rate of incidental durotomy (3.96%) was observed, with 4 cases noted across all procedures.

Conclusions:

  • Ultrasonic bone scalpel (UBS) facilitates a safe, rapid, and effective cervical corpectomy.
  • UBS demonstrated reduced blood loss and fewer intraoperative dural tears compared to traditional methods.
  • The findings support UBS as a beneficial tool for anterior cervical corpectomy and fusion.
