The investigators retrospectively analyzed patients who underwent extraarticular corrective osteotomy of the distal radius via a palmar approach and without the use of a bone graft, even in the absence of cortical contact after corrective osteotomy.

The goal of this retrospective observational study is to determine whether secondary dislocation or nonunion occurs after corrective osteotomy without bone grafting.

Inclusion Criteria:

• malunited distal radius fracture
• extraarticular corrective osteotomy
• palmar approach
• no bone graft used
• no cortical contact after dorsal open wedge osteotomy
• signed informed consent

Exclusion Criteria:

• others reasons for malunion
• intraarticular corrective osteotomy
• use of a bone graft
• cortical contact after open wedge osteotomy
• lost to follow up

All patients with extraarticular corrective osteotomy of the distal radius without cortical contact and without the use of bone graft due to a malunited distal radius fracture
