en Orthopedic Surgery Orthopedic Surgery Original Research Original Research <p> <strong> Abstract </strong></p><p> <strong> Background: </strong>The tibial diaphyseal fractures are the most common type of long </p><p>  bone fractures encountered by most orthopedic surgeons. In accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia </p><p>  fractures have the second incidence of all tibia fractures after the middle tibia fractures. </p><p>  The purpose of the study was to assess the complications and treatment outcome </p><p>  of closed extra-articular distal tibia fracture. </p><p> <strong> Methods: </strong>The results of the management for 76 patients with closed extra-articular </p><p>  distal tibia fracture by intramedullary nailing and plating were reviewed retrospectively. </p><p>  The variables included AO (Arbeitsgemeinschaft fur Osteosynthesefragen) </p><p>  classification of tibia fracture, the mean duration of :::union:::, mal:::union:::, and </p><p>  non:::union:::. </p><p> <strong> Results: </strong>Twenty seven and forty nine patients were treated by intramedullary </p><p>  (IM) nailing and plating respectively. The most common type of fractures was A1 </p><p>  which was observed in twenty five patients. Initial :::union::: and non:::union::: occurred in </p><p>  sixty three and thirteen patients respectively. Eight patients had non:::union::: in plating </p><p>  group and five of twenty seven patients in IM nailing group. Eleven of twenty seven </p><p>  patients in IM nailing group suffered from mal:::union::: while only four patients in the </p><p>  other group had this complication. </p><p> <strong> Conclusion: </strong>The plating Technique in comparison with IM nailing has a satisfactory </p><p>  functional outcome. The technique has a lower incidence of mal:::union::: and </p><p>  non:::union:::, and it should be recommended as a good treatment option for the management of extra-articular closed fracture of distal tibia. </p><p>  </p> Closed extra-articular fracture, management, distal tibia 127 131 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-73&slc_lang=en&sid=1 Seyed Abas Behgoo 20031947532846001830 20031947532846001830 No Iran University of Medical Sciences, Tehran, Iran.
