%0 Journal Article %T A case of patellar fractures in monozygotic twin gymnasts %A Andrew J Beamish %A Gareth L Roberts %A Peter Cnudde %J Sports Medicine, Arthroscopy, Rehabilitation, Therapy & Technology %D 2012 %I BioMed Central %R 10.1186/1758-2555-4-20 %X This is the first published case of identical injury to the patella in monozygotic twins. A significant genetic influence on bone mineral density (BMD) has been reported and low BMD is associated with increased susceptibility to fracture. These injuries corroborate a genetic influence on susceptibility to fracture. There is a requirement for further work to investigate genetic factors influencing susceptibility to fracture. %K Patellar fracture %K Twins %K Gymnast %K Bone mineral density %K Genetic %U http://www.smarttjournal.com/content/4/1/20/abstract
