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

et al. 2011

Les fractures des os sésamoïdes du pied sont rares. Le sésamoïde fibulaire est moins lésé que le tibial. Les traumatismes rencontrés peuvent être directs ou indirects. Nous rapportons le cas d'une fracture du sésamoïde fibulaire secondaire à un traumatisme indirect par hyperextension forcée de la métatarsophalangienne du gros orteil. À travers cette observation et une revue de la littérature, l'anatomie et la biomécanique des os sésamoïdes seront rappelées, le mécanisme et les modalités diagnostiques et thérapeutiques des fractures du sésamoïde seront discutés. Pour citer cette revue : Méd. Chir. Pied 27 (2011). Mots clés Sésamoïde fibulaire · FractureAbstract Fractures of the sesamoid bones of the foot are rare. Injuries to the fibular sesamoid are less compared to the tibial. The mechanism of trauma may be direct or indirect. We report the case of a fracture of fibular sesamoid secondary to indirect trauma by forced hyperextension of the metatarsophalangeal joint of the hallux. Through this observation and a review of the literature, anatomy and biomechanics of the sesamoid bones will be recalled as the mechanism and modalities of diagnosis and treatment of sesamoid fractures are discussed.

“…If a previously solitary ossicle appears multipartite at follow-up, or if a multipartite ossicle demonstrates diastasis between fragments, the diagnosis can be rendered with confidence. Irregularity of the margins of the fragments without sclerosis should raise the index of suspicion for an acute fracture [10]. Ultimately, MRI remains the best modality for further evaluating patients with persistent focal pain from a non-displaced fracture, although bone scintigraphy is also useful when MRI is not available.…”

“…There have been several mechanisms proposed to explain the occurrence of a fracture of an os peroneum. The two most commonly proposed mechanisms are either direct trauma to the midfoot or violent dorsiflexion of the ankle and foot [7,8,10]. A less common mechanism is eversion against a supinated foot and ankle [6].…”

“…It is important to use multiple radiographic projections, including oblique views, to adequately examine the ossicle. If a fracture of the os peroneum is a consideration, MR imaging or ultrasound can be useful to further evaluate the peroneus longus tendon [10]. A ruptured peroneus longus tendon that is associated with a fracture of the os peroneum may be treated conservatively or surgically [3,10].…”

“…Its prevalence on radiographs has been reported variably up to 30% [11]. The OP has occasionally been associated with acute traumatic or chronic attrition injuries of the PLT, especially in a cavovarus foot [12]. However, the mere presence of an OP does not predispose to degenerative tendon disease [11].…”

ABSTRACT. In spite of highly efficient diagnostic modalities at our disposal, pathological conditions of the peroneal tendons still tend to be underdiagnosed as a cause of lateral ankle pain. The purpose of this review is to summarise and illustrate common and less common MRI findings in repetitive or single mechanical lesions of the peroneal region as well as predisposing anatomical variants. Peroneal tendon (PT) pathology is not uncommon, but is infrequently reported in the literature. It is the main differential diagnosis of lateral ankle pain, next to capsular and ligamentous injuries. Given that normal tendons hardly ever get torn as a result of a single trauma, anatomical predisposition plays an important role in the pathogenesis of degenerative tendinosis and subsequent partial or complete tears of the PT. Rather infrequent causes for primary tenosynovitis are inflammatory conditions of the tendon sheath, e.g. rheumatic or infectious diseases [1]. Ruptured tendons typically exhibit pre-existing degenerative changes on biopsy studies [2]. In spite of some limitations, MRI is the current method of choice for imaging tendons and fibrocartilage. The MRI appearance of different types and grades of tendon injuries has been exhaustively described [3]. T 2 weighted images perpendicular to the tendon course are particularly appropriate for visualising tendinosis and partial or complete tendon rupture, as well as inflammatory changes of the tendon sheath (tenosynovitis). We used T 2 * gradient echo (GRE) sequences as well as T 2 fast spin echo (FSE) sequences; the higher sensitivity of the former allowed for detection of degenerative or traumatic lesions of fibrocartilage [4] and crystal or haemosiderin deposits in the tendon sheaths. However, when looking for tendinosis, the magic angle effect (MAE) must be considered as a source of bright signal in healthy tendons. With short echo time sequences, a signal increase in the absence of morphological change is a normal physical phenomenon in tendons oriented at approximately 55 u to the main magnetic field (Figure 1). Because PTs change direction along their course, the MAE cannot be avoided completely by positioning the foot [5]. The change in Bright signal of both the peroneus brevis tendon and the peroneus longus tendon below the lateral malleolus owing to the magic angle effect in a T 1 SE sequence. The foot is positioned at approximately 10 u plantar flexion with the patient supine in a closed MR scanner with cephalocaudad main field direction.Cite this article as: Schubert R.
