AI Article Synopsis

  • * The first plantar interossei originated from the lateral side of the first metatarsal and connected to the great toe, while the second and third interossei were attached to the second and third metatarsals, respectively, inserting into their corresponding toe phalanges.
  • * Notably, the absence of the third and fourth intermetatarsal spaces suggests these muscles were missing, raising important clinical considerations regarding their functional impact.

Article Abstract

The variations in the attachment of plantar interossei might affect the gait of the individual and also raise questions about the function of this muscle at the tarsometatarsal joints. During routine dissection of the right lower limb, we encountered a unique variation in the attachment of plantar interossei. The first plantar interossei took origin from the lateral side of the base of the first metatarsal and inserted into the lateral side of the base of the proximal phalanx of the great toe. The second and third plantar interossei took origin from the medial surface of the base of the second and third metatarsals, respectively, and inserted into the medial side of the base of the proximal phalanges of the corresponding digits. The third and fourth intermetatarsal spaces were void, indicating the absence of these muscles from those spaces. The clinical significance of this variation has been discussed.

Introduction: In classic ballet, choreography often involves tiptoe standing. Tiptoe standing requires a high and stable foot arch structure, which is achieved by contraction of the plantar intrinsic foot muscles (PIFMs). Long-term repetitive loading with a specific movement can induce hypertrophic adaptation of the associated muscles.

Background The aim of the present biomechanical study on cadavers was to determine both the center of rotation of the metatarsophalangeal joints and the position of the tendons of the interosseous muscles after the Weil and triple Weil osteotomies, and to compare these parameters in order to clarify the pathogenesis of dorsal stiffness and floating toe. Materials and methods Seven fresh-frozen cadaveric feet were utilized. After completing the preparation of both the plantar and the dorsal surface, we performed the dissection of the entire second, third and fourth rays, and each ray was fixed to a wooden wall mounted on a movable frame.

Wallabies are small- to medium-sized hopping marsupials and have large and flexible tendons in their hind limbs that act like springs. This study aimed to show the morphological pattern of the pes tendons in Bennett's wallaby. Two Bennett's Wallabies (Macropus rufogriseus) that died of natural causes have been used for this study.
