(LMC) total length of LMC-the distance between its origin at the anterior crest (AC) and the most distal point of LM, (F) length of the fibula-the distance between the apex of the fibular head and the most distal point of LM, MethodĮach fibula was assessed in terms of incidence of LMC and its influence on the shape of the lateral surface of the lateral malleolus (LM). Their mean age was, 51 years (range 22–81) in men, 54 years (23–86) in women and 52 years (range 23–86) in the whole group. The resulting study group comprised 352 fibulae (176 pairs), of these 192 male (96 pairs) and 160 female (80 pairs) samples. Įxcluded from the study were all specimens with pathological changes, signs of damage and unpaired specimens. This collection, created in 1934–1935, provides basic data on each skeleton, including the individual´s gender and age at the time of death. The present study is based on examination of adult fibulae, both male and female, from the Pachner´s osteological collection of the Institute of Anatomy, 1st Faculty of Medicine, Charles University, Prague. This crest, which we have termed crista malleoli lateralis (lateral malleolar crest-LMC), is in our view highly important in clinical terms, and therefore we have decided to focus in detail on its anatomy. Only two authors mentioned also its clinical importance. This structure was very briefly described only by a few authors. Some anatomical textbooks and atlases present its image, but without an official term. Even if this crest is well known from CT axial sections of the ankle, nobody has focused on it yet. An exception are only a few studies, which, however, did not deal with the anatomy of the fibular malleolus.ĭuring analysis of the pathoanatomy of posterior malleolus fractures, Maisonneuve fractures (MF) and assessment of the position of the distal fibula in the fibular notch, we have noticed on 3D CT reconstructions a prominent curved ridge on the lateral surface of the distal fibula, giving the characteristic shape to the lateral aspect of the fibular malleolus. Somewhat disregarded in this context has been, for a long time, the distal fibula, although it is a very important structure, essential for the function of the ankle. Progress in diagnosis and treatment of ankle fracture–dislocations has been considerably influenced by anatomical studies that have brought many new findings, particularly as concerns the tibiofibular syndesmosis, fibular ligaments and the deltoid ligament. The knowledge of its anatomy is essential for placement of syndesmotic screws or/and the fibular plate. LMC is an important structure on the lateral malleolus. Materials and methodsĪ total of 352 dry fibulae were analyzed and the following parameters recorded: (F) length of the fibula, (LMC) total length of LMC, (A) length of the part of the examined crest from the superior border of the articular facet of the lateral malleolus (AFLM) to its most proximal intersection with the midline of the fibula, (B) height of the medial triangular rough surface, and (A/F) A/F ratio. As, in their view, LMC is a clinically important structure which was only briefly mentioned by a few authors without an official term, they focused on the anatomy of this structure. During study of anatomy of a fractured posterior malleolus of the ankle on CT scans, the authors noticed a prominent crest on the lateral malleolus, which they termed the lateral malleolar crest (LMC).
