Summary
Acetabular fractures with hip dislocation often leave intra-articular fragments. Early surgical removal of these fragments is crucial to prevent hip arthritis and ensure proper reduction of acetabular fractures.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
- Radiology
Background:
- Acetabular fractures frequently occur with femoral head dislocations.
- Intra-articular fragments can persist after dislocation reduction, particularly in posterior dislocations.
- These fragments may impede complete reduction and risk joint damage.
Purpose of the Study:
- To analyze the incidence and management of intra-articular fragments following acetabular fracture-dislocations.
- To emphasize the importance of early surgical intervention and imaging for optimal outcomes.
Main Methods:
- Retrospective review of 373 acetabular fracture cases from 1997-2007.
- Analysis of 127 cases with associated hip dislocations (anterior, central, posterior).
- Evaluation of fragment detection using computed tomography (CT) scans.
Main Results:
- 109 posterior dislocations were observed, with 43 cases presenting intra-articular fragments post-reduction.
- Fragments were found in 45 of 127 dislocation cases.
- Computed tomography scans are essential for pre- and post-operative assessment of fragments.
Conclusions:
- Intra-articular fragments in acetabular fracture-dislocations necessitate removal to prevent cartilage damage and early arthritis.
- Surgical approach and strategy for fragment removal vary based on dislocation type.
- Early intervention and comprehensive imaging are vital for managing these complex injuries.

01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:16Structural Joints: Synovial Joints
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
01:09Functional Classification of Joints
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:26Joints
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
