Ankle Joint

Ankle Joint

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

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...

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...

Bones of the Upper Limb: Ulna

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...

Bone Disorders

Bone Disorders

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...

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 group...

Area of Science:

Orthopaedics
Medical Genetics

Background:

Congenital talonavicular coalition is a rare tarsal coalition, accounting for approximately 1% of all cases.
While often autosomal-dominant, tarsal coalition can also be inherited as an autosomal-recessive trait.
Associated anomalies include symphalangism, clinodactyly, and other tarsal coalitions.

Observation:

A 24-year-old woman presented with symptomatic bilateral talonavicular coalitions.
She exhibited previously unreported associated anomalies: nail hypoplasia and metatarsus primus elevatus.
Patients with talonavicular coalitions are typically asymptomatic and rarely require surgical intervention.

Findings:

The patient underwent calcaneocuboid joint distraction arthrodesis and first metatarsal osteotomy.
At 1-year follow-up, she was pain-free with improved foot alignment and radiographic evidence of arthrodesis consolidation.
This case demonstrates that symptomatic talonavicular coalitions can necessitate surgical treatment.

Implications:

Symptomatic talonavicular coalition, though uncommon, can significantly impact quality of life.
Surgical intervention can provide effective pain relief and functional improvement.
Recognition of associated anomalies is crucial for comprehensive patient management.
