Ankle Joint01:10

Ankle Joint

3.7K
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

5.1K
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....

Microtubule Instability02:17

Microtubule Instability

6.5K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Summary

Subtalar instability, often missed in chronic ankle issues, requires clinical suspicion. Treatment involves nonoperative methods initially, with surgical reconstruction for persistent cases.

Area of Science:

  • Orthopedic surgery
  • Sports medicine
  • Biomechanics

Background:

  • Subtalar instability is a frequent clinical condition.
  • It often presents as persistent pain in the sinus tarsi despite management for chronic lateral ankle instability.
  • A high index of suspicion is crucial for diagnosis.

Purpose of the Study:

  • To highlight the diagnostic considerations for subtalar instability.
  • To outline current management strategies for subtalar instability.
  • To suggest future research directions.

Main Methods:

  • Review of clinical presentations and diagnostic challenges.
  • Discussion of nonoperative and operative treatment modalities.
  • Analysis of existing literature on subtalar joint stabilization.

Main Results:

  • Subtalar instability should be considered in patients with chronic lateral ankle instability who have failed conservative treatment.
  • Nonoperative management is the primary approach.
  • Operative management involves reconstruction of lateral stabilizers.

Conclusions:

  • Early recognition and diagnosis of subtalar instability are essential.
  • A stepwise treatment approach, starting with nonoperative care, is recommended.
  • Further research should focus on enhancing diagnostic accuracy and recognition of this condition.
