Management of a Delayed Union Sesamoid Fracture in a Dancer

Abstract

insert into the medial and lateral sesamoids, respectively. The intermetatarsal ligament also anchors the lateral sesamoid to the second MTP joint plantar plate.5 A fat-pad cushion and bursa separates the plantar dermis and the sesamoids. 57 In general, the medial sesamoid is larger and longer and the lateral sesamoid is smaller, rounder, and protected by the soft tissue of the first intermetatarsal space. 5,43The sesamoids protect the first metatarsal head by absorbing shock, increasing the FHB and FHL moment arms, and protecting and guiding the FHL passing between them. [3][4][5]53 The estimated resultant force acting across the first metatar-D ancers comprise a unique athletic population. They execute repetitive foot and ankle motions (alternating between extreme plantar flexion and dorsiflexion) with minimal to no supportive footwear, which predisposes them to overuse injuries of the foot and ankle. 10,11,39 Dancers apply a large amount of stress to the hallucal sesamoids when moving onto their toes to grand plié and demi-relevé (ankle plantar flexion and metatarsophalangeal [MTP] joint dorsiflexion), full relevé (ankle and MTP joint plantar flexion), and during eccentric deceleration occurring with jumps and hops. 14,53,58 STUDY DESIGN: Case report.

Management of Dancers With Symptomatic Accessory Navicular: 2 Case Reports

“…The progression of dance activities was similar to previously reported protocols for forefoot injuries in dancers. 6,8 The initial phase involved no dance activities and focused on pain management and restoring ROM. Activities were progressed from initially non-weight-bearing to double-leg to single-leg weight-bearing, flatfoot to relevé, and parallel to turned-out positions.…”

“…The Dance Functional Outcome System is the only dance-specific lower extremity questionnaire available at this time and has been used to describe outcomes in previous case reports. 6,8 Preliminary studies…”

Fracture de l’os sésamoïde fibulaire: à propos d’une observation et revue de la littérature

“…La tomodensitométrie présente une sensibilité élevée mais une spécificité relativement faible, ne permettant pas toujours de poser un diagnostic de certitude [2,6,7,12,[18][19][20][21].…”

“…S'y insèrent le chef oblique du muscle adducteur de l'hallux (adductor hallucis) et le ligament métatarsosésamoïdien latéral. Les os sésamoïdes sont reliés entre eux par un ligament intersésamoïdien isolant en superficie le tendon du muscle long fléchisseur de l'hallux (flexor hallucis longus), entouré de sa gaine synoviale, qui passe dans une gouttière formée par ces deux os [1,6,7].…”

Repair and Rehabilitation of Extensor Hallucis Longus and Brevis Tendon Lacerations in a Professional Dancer

“…3 The DFOS is a dance-specific lower extremity questionnaire. 7,9 This instrument was developed upon finding ceiling effects when using region-specific measures and problems with validity when using sport-specific measures. A preliminary study indicates high reliability, validity, and responsiveness of the DFOS when compared to the SF-36, but further study is necessary.…”
