Bone Remodeling

Bone Remodeling

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.

Fractures: Bone Repair

Fractures: 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...

Bones of the Lower Limb: Tibia and Fibula

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Bone Remodeling and Repair

Bone Remodeling and Repair

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...

Summary

Osseointegration for limb amputation requires careful stump refashioning, especially for transfemoral cases. Effective soft tissue management is crucial for preventing complications and improving patient quality of life after osseointegration surgery.

Background:

Osseointegration is an advanced limb amputation technique facing challenges in managing the permanent stoma.
Limited literature and surgical options exist for effective stoma management in residual limbs.

Purpose of the Study:

To investigate soft tissue management strategies for improving surgical outcomes in osseointegration.
To describe surgical techniques for stump refashioning in transfemoral and transtibial osseointegration.

Main Methods:

Retrospective evaluation of 406 osseointegration patients (251 transfemoral, 155 transtibial) from December 2010 to December 2023.
Analysis of stump refashioning rates in transfemoral (32.9%) and transtibial (20.9%) osseointegration cases.

Main Results:

Stump refashioning was required in 87 of 264 transfemoral cases (32.9%).
Stump refashioning was performed in 37 of 177 transtibial cases (20.9%).

Conclusions:

Careful soft tissue management is vital for successful stump refashioning in osseointegration.
Addressing stoma pain, tissue overhang, and infections prevents complications.
Improved surgical techniques enhance patient quality of life after osseointegration.
