Abstract
Objective: The purpose of the present study was to report on the author’s experience using injectable cement as a bony substitute in distal radius corrective osteotomies. The interest of such a bone substitute is the real capacity to adapt itself to the bone defect. Harvesting a trapezoidal cortico spongious graft which can fill very precisely the void and not more remains a challenging objective in treating extra articular mal union.
Material and Methods: 5 patients with an average age of 57 yo (42–74) had a corrective osteotomy for a malunited distal radius fracture using Injectable bone substitute (Eurobone, Jectos, Kasios Inc) as an alternative to an autogenous bone graft. Internal fixation of the osteotomy was achieved by using one plate without post operative immobilisation. Two patients were stiff at preoperative time.
Results: At an average follow-up evaluation of 26 months (14–37 mo) all the osteotomies united. Wrist flexion-extension motion improved from 56° to 110°, forearm rotation increased from 112° to 142°, and grip strength had an average increase of 120% at the time of the final follow-up evaluation. All patients were satisfied but there one report of persistent pain. Radiographic evaluation showed an average volar tilt improvement from a preoperative dorsal angulation shifting into a neutral position in the sagittal plane; Radiographically the injectable cement showed evidence of progressive re-absorption over time but with no complete disappearance.
Conclusions: On the basis of this preliminary experience it is reasonable to consider injectable cement as a viable alternative to bone grafting in conjunction with surgical correction and internal fixation of extra articular distal radius malunion.
