Summary
First metatarsal axial rotation is a key factor in hallux valgus (HV) deformity. Understanding this rotation is crucial for accurate diagnosis and effective surgical treatment of hallux valgus.
Area of Science:
- Orthopedics
- Podiatry
- Biomechanics
Background:
- First metatarsal (M1) rotation has long been recognized as a potential cause of hallux valgus (HV).
- Traditional 2D imaging limited the understanding and treatment of M1's axial rotation in HV.
- Advances in imaging technology have renewed focus on M1 axial rotation in HV pathoanatomy.
Purpose of the Study:
- To review the historical perspective of M1 rotation in hallux valgus.
- To present current understanding of M1 rotation's role in HV etiology and pathogenesis.
- To summarize imaging and operative considerations related to M1 rotation in HV.
Main Methods:
- Systematic review of existing literature.
- Analysis of historical and current understanding of M1 rotation in hallux valgus.
- Evaluation of imaging and surgical techniques relevant to M1 rotation.
Main Results:
- M1 axial rotation is increasingly recognized as significant in hallux valgus development.
- Advanced imaging aids in understanding the 3D nature of M1 rotation.
- Specific measurement and surgical techniques are evolving to address M1 rotation.
Conclusions:
- M1 axial rotation is a critical component of hallux valgus pathoanatomy.
- Accurate assessment and management of M1 rotation are essential for successful hallux valgus treatment.
- Further research into the biomechanical implications of M1 rotation is warranted.

01:10Ankle Joint
2.2K
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...

01:28Muscles of the Leg that Move the Foot and Toes
3.2K
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....
