[Osteogenesis imperfecta: Treatment and results of a case series]

To describe our experience in the management of patients with osteogenesis imperfect (OI).

We conducted a retrospective study of a series of cases affected with OI treated in the Clínica Univesidad de Navarra from 1980 to 2007, with a mean follow up of 17.3 years (7-27 years). We collected descriptive data of the sample, the fractures and the deformities, and the treatments given. The complications presented and the functional outcomes at the end of follow-up were also reviewed.

The sample included ten patients. Approximately two-thirds (65%) of fractures were sustained in the lower limbs. One patient received medical treatment only. Three patients had combined medical and surgical treatment. Some type of surgical treatment was performed on 6 patients. The most common surgery was the Sofield-Millar performed on 37 occasions, with a third of them requiring revision surgery due to migration of the nails. There were 17 episodes of re-fracture. Complications such as non-union, iatrogenic fractures, and infections, were also observed. The functional outcome, according to the Hoffer-Bullock scale, at the end of follow-up was grade I/II in 7 patients.

Despite the need for multiple interventions and complications presented during follow up, the appropriate treatment of patients with OI can provide acceptable functional outcomes.
