en A congenital fibular notch synostosis of the left distal leg: a case report عمومى General گزارش مورد case report Background & Aims: Tibiofibular synostosis is an infrequent, limb malformation that is non-syndromic and illustrated by the union of the proximal or distal tibia and union of the proximal or distal tibial and fibular metaphysis and/ or diaphysis. Congenital tibiofibular synostosis is a very rare anomaly and if there are no related syndromes or distortions, the cause may be unknown or acquired. The case presented here shows a fusion of the tibia and fibula at the fibular notch which is not secondary to a fracture, hematoma, or any procedure done to fix the distal tibiofibular joint, as shown by the x-ray radiograph. Among other factors, calcification of bleeding into the surrounding tissue may result in the fusion of the tibia and fibula. Case Presentation: After macerating the bone of a 56-year-old Nigerian male cadaver in the Anatomy Program, Bowen University, Nigeria, a dried adult left tibia and fibula with ossification at the distal end of both bones were observed. Anteriorly, a nutrient foramen was present where the anterior tibial vessels pass, while a number of grooves were observed posteriorly at the fused end. Thorough observation showed fusion of the distal tibiofibular syndesmosis joint with the absence of callus formation and /or a fracture. A bone specimen of distal tibiofibular synostosis and its medical importance are hereby highlighted. Conclusion: Cases of congenital distal tibiofibular synostosis are rare. When present in a living person, this should be suggestive to the physician who may be treating a patient who complains of ankle pain of unknown etiology. This is known to be a common reason for pain in the anterior leg compartment, usually associated with sports activities which may present with ankle pain as a result of abnormal ankle function.  Acquired, Case report, Congenital, Synostosis, Tibiofibular 202 206 http://ijrabms.umsu.ac.ir/browse.php?a_code=A-10-461-1&slc_lang=en&sid=1 Olubunmi Balogun olubunmi.balogun@bowen.edu.ng 10031947532846004171 0009-0008-2452-8148 Yes Department of Anatomy, Bowen University, Iwo, Nigeria Oladayo oyedun oyedundayo@yahoo.com 10031947532846004172 10031947532846004172 No Department of Anatomy, College of Medicine, University of Ibadan, Nigeria Olaniran Morakinyo olaniran.morakinyo@bowen.edu.ng 10031947532846004173 10031947532846004173 No Department of Anatomy, Ladoke Akintola University of Technology, Ogbomosho, Nigeria Olusegun Ajeleti segun.ajeleti@bowen.edu.ng 10031947532846004174 10031947532846004174 No Department of Anatomy, Bowen University, Iwo, Nigeria Olaleye Olabiyi olaleye.olabiyi@bowen.edu.ng 10031947532846004175 10031947532846004175 No Department of Anatomy, Bowen University, Iwo, Nigeria Gideon Ojo gideon.ojo@bowen.edu.ng 10031947532846004176 10031947532846004176 No Department of Anatomy, Bowen University, Iwo, Nigeria Abayomi Olubintan haybeywhy@gmail.com 10031947532846004177 10031947532846004177 No Funbell Diagnostics, Ibadan
