Ankle Joint01:10

Ankle Joint

1.4K
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...

Muscles of the Leg that Move the Foot and Toes

1.2K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Summary
This summary is machine-generated.

Anterior ankle impingement, characterized by pain during dorsiflexion, has varied causes. An etiological and topographic classification guides treatment, often involving arthroscopic removal of bone spurs and soft tissues for improved pain and function.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Anatomy

Background:

  • Anterior ankle impingement understanding has evolved significantly over 70 years.
  • Diagnosis and treatment strategies have undergone substantial changes.
  • This study updates current knowledge on anterior ankle impingement.

Purpose of the Study:

  • To provide an updated overview of anterior ankle impingement.
  • To discuss diagnostic criteria, including palpation, dorsiflexion, squatting, and Molloy's sign.
  • To review diverse etiologies and propose an improved classification system for treatment guidance.

Main Methods:

  • Review of current literature and clinical understanding of anterior ankle impingement.
  • Discussion of diagnostic methods, emphasizing clinical signs and the role of MRI.
  • Proposal of an etiological and topographic classification system.

Main Results:

  • Anterior ankle impingement presents with pain exacerbated by dorsiflexion and specific clinical signs.
  • Etiologies include tumors, trauma, instability, osteoarthritis, and microtrauma.
  • An etiological and topographic classification is more effective than previous models for guiding treatment.

Conclusions:

  • Anterior ankle impingement requires accurate diagnosis through clinical evaluation and advanced imaging like MRI.
  • An etiological and topographic classification system aids in tailoring treatment strategies.
  • Arthroscopic intervention is often effective for microtrauma, instability, or osteoarthritis-related impingement, leading to good outcomes.
