Summary
A rare posterior cervical hemivertebra caused instability in a child. Surgical correction using an anterior approach with corpectomy and plating achieved effective cervical stabilization.
Area of Science:
- Orthopedic Surgery
- Pediatric Neurosurgery
- Spinal Deformity
Background:
- Hemivertebrae typically cause thoracic or lumbar scoliosis due to vertebral formation defects.
- Cervical hemivertebrae are uncommon, and their association with cervical instability is exceptionally rare.
Observation:
- A 7-year-old female presented with a posterior C4 hemivertebra and C5-C7 left hemiblock, causing cervical instability.
- The patient underwent a C4 corpectomy with anterior fixation, intersomatic grafting, and plating.
Findings:
- The surgical intervention resulted in adequate cervical stabilization.
- Postoperative complications included self-limiting left C6 brachialgia and ipsilateral Horner syndrome.
Implications:
- This case highlights the rarity of posterior cervical hemivertebrae causing instability.
- Anterior corpectomy and plating provide a viable surgical solution for this condition.

01:27Muscles of the Vertebral Column
3.9K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

01:28Articulations of the Vertebral Column
3.7K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:30General Structure of a Vertebra
8.3K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

01:16Vertebral Column: Regions and Curvature
11.6K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

01:17Structural Joints: Cartilaginous Joints
4.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
