[Post-traumatic growth impairment following pediatric distal radius fractures resulting in an ulnar variance : A case...

Fractures of the distal forearm are common in children. While we treat adults by trying to anatomically reconstruct the wrist joint, in children, fracture treatment is predominantly conservative due to the high correction potential of the distal growth plate. However, the presentation of young adults with post-traumatic wrist pain is not unusual.

Do pediatric distal forearm fractures really heal without consequences despite a large tolerance of axial deviation?

Review of the literature, discussion of results and case report.

Positive ulnar variance is the most common sequelae of pediatric distal forearm fractures. A positive variance of as little as >2 mm frequently causes ulnar-sided wrist pain and loss of motion, as is also shown in our case.

Careful follow-up is advisable beyond fracture union following pediatric distal forearm fractures, especially after transphyseal osteosynthesis or growth plate involvement. Reconstructively corrective osteotomy of the ulna should be considered in patients with corresponding clinical symptoms, radiological findings and a positive ulnar variance of >2 mm.
