Development of the Limb Synovial Joints

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Knee Joint

Knee 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...

Area of Science:

Orthopedic Surgery
Biomedical Engineering

Background:

Revision total hip arthroplasty (THA) is complex, often complicated by femoral bone defects from prior surgeries or aseptic loosening.
A modular fluted tapered system, established in 2003 and used in over 180,000 procedures, aids surgeons in managing these challenging cases.

Purpose of the Study:

To evaluate the efficacy and advantages of a newly introduced short-stem modification (115mm) of a modular fluted tapered hip revision system.
To demonstrate the versatility of the short-stem components in addressing diverse femoral bone defect scenarios during revision THA.

Main Methods:

A case series of six distinct patients undergoing revision total hip arthroplasty.
Utilized a modified modular fluted tapered system with newly available shorter stem components (115mm).
Documented the application of the short-stem system across various complex revision scenarios.

Main Results:

The case series successfully demonstrated the application of the new 115mm short-stem components in revision THA.
The modified system proved effective in managing unique patient challenges and diverse femoral bone defects.
The shorter stem components provided a viable option for complex hip revision procedures.

Conclusions:

The modified modular fluted tapered system, with its new short-stem option, is a valuable tool for addressing complex revision total hip arthroplasty cases.
This modification expands the applicability of the system, offering solutions for a wider range of femoral bone defect presentations.
The presented cases highlight the reliability and effectiveness of the short-stem components in challenging revision scenarios.
