Summary
Hallux rigidus, a common MTPJ degeneration, causes pain and stiffness. This review covers its anatomy, biomechanics, and current understanding of the disease process.
Area of Science:
- Orthopedics
- Rheumatology
- Podiatry
Background:
- Hallux rigidus is a prevalent degenerative condition affecting the first metatarsophalangeal joint (MTPJ).
- It manifests as pain, swelling, stiffness, and restricted motion.
- Established risk factors include trauma, family history, hallux valgus interphalangeus, and inflammatory arthropathies.
Purpose of the Study:
- To review the normal and pathological anatomy of the hallux MTPJ.
- To examine the biomechanics of the hallux MTPJ.
- To provide an overview of the current understanding and ongoing debates regarding hallux rigidus.
Main Methods:
- Literature review of anatomical and biomechanical studies.
- Synthesis of clinical, physical examination, and radiographic findings.
- Analysis of etiological factors and disease progression.
Main Results:
- Detailed description of hallux MTPJ anatomy and biomechanics.
- Identification of key clinical and radiographic hallmarks of hallux rigidus.
- Summary of established and debated etiological factors.
Conclusions:
- Hallux rigidus is a complex degenerative joint disease with multifactorial etiology.
- Understanding MTPJ anatomy and biomechanics is crucial for diagnosis and management.
- Further research is needed to resolve ongoing debates regarding its pathogenesis.

01:15Bones of the Upper Limb: Ulna
2.1K
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...

01:09Bones of the Upper Limb: Radius
2.2K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

01:19Bones of the Upper Limb: Humerus
3.1K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:10Ankle Joint
1.5K
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...

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.

01:22Sutures of the Skull
6.5K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
