Ankle Joint01:10

Ankle Joint

3.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Bones of the Lower Limb: Tibia and Fibula

14.8K
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 Disorders01:29

Bone Disorders

7.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Compact Bone01:27

Compact Bone

20.6K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

4.5K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Knee Joint01:23

Knee Joint

3.7K
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...

Summary
This summary is machine-generated.

Talocalcaneal coalitions cause flatfeet and ankle pain. Resection surgery with fat-grafting offers better outcomes than fusion, improving foot function scores significantly.

Area of Science:

  • Orthopedics
  • Podiatry
  • Foot and Ankle Surgery

Background:

  • Talocalcaneal coalitions are abnormal bony or fibrous fusions between the talus and calcaneus.
  • They often manifest as pediatric flatfoot, hindfoot pain, or recurrent ankle instability.
  • Clinical signs include limited subtalar joint motion and a medial malleolar prominence.

Purpose of the Study:

  • To evaluate the efficacy of talocalcaneal coalition resection with fat-graft interposition.
  • To compare surgical outcomes with primary arthrodesis for treating talocalcaneal coalitions.
  • To assess functional improvement using the American Orthopaedic Foot & Ankle Society (AOFAS) score.

Main Methods:

  • Surgical resection of talocalcaneal coalitions.
  • Intraoperative computed tomography (CT) for confirmation of complete resection.
  • Interposition of autologous fat graft into the resected coalition site.
  • Preoperative and postoperative assessment using AOFAS foot scores.

Main Results:

  • Resection with fat-graft interposition demonstrated superior outcomes compared to primary arthrodesis.
  • Patients reported significant functional improvement post-surgery.
  • Average AOFAS foot scores improved to 90/100 after resection.

Conclusions:

  • Surgical resection of talocalcaneal coalitions, augmented with fat-graft interposition, is an effective treatment.
  • This technique yields better functional results than primary arthrodesis.
  • It provides a reliable solution for patients suffering from symptomatic talocalcaneal coalitions.
