Summary
The medial flexor hallucis brevis (FHB) insertion is longer than the lateral. To preserve FHB function, resections should not exceed 4mm or 13% of phalangeal length from the defined reference plane.
Area of Science:
- Anatomy
- Orthopedic Surgery
Context:
- The flexor hallucis brevis (FHB) muscle is crucial for great toe function.
- Understanding its insertion anatomy is vital for first metatarsophalangeal (MTP) joint surgeries.
Purpose:
- To detail the morphology of FHB insertion sites.
- To establish safe resection margins at the proximal phalangeal base.
Summary:
- This study measured FHB insertion lengths in 36 cadaver specimens.
- The medial insertion site was longer than the lateral, making the lateral site critical for function.
- A reference plane was identified for optimal surgical resection.
Impact:
- Provides anatomical data to guide surgeons in MTP joint procedures.
- Aims to minimize complications by defining safe resection limits.
- Contributes to preserving FHB function and great toe stability post-surgery.

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

01:16Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

01:10Bones 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...
01:10Ankle 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...
