Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

5.0K
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....

Deformation in a Circular Shaft01:10

Deformation in a Circular Shaft

1.0K
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...

Ankle Joint01:10

Ankle Joint

3.4K
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...

Deformation of Member under Multiple Loadings01:11

Deformation of Member under Multiple Loadings

677
When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

Plastic Deformation in Circular Shafts01:20

Plastic Deformation in Circular Shafts

623
When materials are subjected to forces that surpass their yield strength, they undergo a process known as plastic deformation. This results in a permanent alteration or strain in their structure. This concept can be specifically applied to circular shafts, where the deformation leads to a change in its shape. The precise evaluation of this plastic deformation requires understanding the stress distribution within the circular shaft, which is achieved by calculating the maximum shearing stress in...

Functional Classification of Joints01:09

Functional Classification of Joints

8.0K
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.
Synarthrosis

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Traumatology

Background:

  • Closed tibiofibular shaft fractures can lead to complex foot deformities.
  • Tendon tethering, affecting both flexor and extensor tendons of the hallux, is an uncommon complication.
  • Dynamic positional deformities of the hallux require specific diagnostic and therapeutic approaches.

Observation:

  • A case of concomitant flexor hallucis longus and extensor hallucis longus tendon tethering is presented.
  • The deformity occurred subsequent to closed tibiofibular shaft fractures.
  • This resulted in a dynamic positional deformity of the hallux.

Findings:

  • Surgical management involved tenotomy of the flexor hallucis longus tendon.
  • Z-plasty lengthening of the extensor hallucis longus tendon was performed.
  • Good clinical results were achieved with this combined operative approach.

Implications:

  • This case highlights a rare but treatable complication of tibiofibular fractures.
  • The described surgical techniques offer a viable solution for combined hallux tendon tethering.
  • Further research into operative methods for such combined deformities is warranted.
