Unusual Forearm Deformity Solved by 3D Custom Made Guides.

We report a case of a symptomatic forearm deformity due to a premature distal ulnar fracture solved by 3D custom made cutting guides. Our patient is a sixteen years old girl referred to us due to a forearm deformity and a dysplasic ulnar head associated to pain at the dorsum of the distal ulna and at the radial head at the elbow. Using custom-made cutting guides on a 3D model, a both bone forearm osteotomy was performed. At 18 months of follow up, the range of motion did not improve significantly but our patient referred no pain and she was satisfied with the procedure. The accuracy of single cut osteotomies, utilizing three-dimensional planning and custom patient guides has been previously established. This technique helped with the pain in our case.
