Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

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...
Overview of the Axial Skeleton01:09

Overview of the Axial Skeleton

The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.
The axial skeleton of the adult...
General Structure of a Vertebra01:30

General Structure of a Vertebra

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 column.
Introduction to Joints00:58

Introduction to Joints

The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no movement.
Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

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 or...
Introduction to the Skeletal System01:20

Introduction to the Skeletal System

The skeletal system is the central framework of the body, consisting of different connective tissues: bones, cartilage, tendons, and ligaments.
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...

Summary

This study examines how coexisting lumbar spine disorders affect total hip arthroplasty outcomes and costs. Findings suggest these spinal conditions may influence patient recovery and healthcare expenses following hip replacement surgery.

Area of Science:

  • Orthopedic surgery
  • Spine disorders
  • Hip arthroplasty outcomes

Background:

  • Total hip arthroplasty (THA) is a common procedure for hip arthritis.
  • Coexisting lumbar spine disorders are frequently observed in patients undergoing THA.
  • The impact of these spinal conditions on THA outcomes is not fully understood.

Purpose of the Study:

  • To investigate the association between lumbar spine disorders and clinical outcomes after THA.
  • To evaluate the effect of coexisting lumbar spine disorders on physician charges related to THA.
  • To provide insights into managing patients with combined hip and spine pathology.

Main Methods:

  • Retrospective review of patients undergoing THA.
  • Analysis of clinical outcomes, including pain, function, and complication rates.
  • Assessment of physician charges and resource utilization.
  • Comparison between patients with and without coexistent lumbar spine disorders.

Main Results:

  • Patients with lumbar spine disorders demonstrated altered clinical outcomes post-THA.
  • Significant differences were observed in physician charges between the two groups.
  • Lumbar spine pathology may be an independent predictor of THA outcomes and costs.

Conclusions:

  • Coexistent lumbar spine disorders significantly impact clinical outcomes and physician charges following total hip arthroplasty.
  • Consideration of spinal health is crucial for optimizing THA patient management.
  • Further research is warranted to elucidate the mechanisms and guide treatment strategies.
