Use of Bone-Graft Substitutes in Distal Radius Fractures

Treatment of distal radius fractures with a volar fixed angle plate achieves sufficient stabilisation and permits early physical exercise. However, secondary displacement after surgery sometimes occurs in elderly patients with a metaphyseal comminution and/or cases in which the subchondral support pegs were not placed immediately below the subchondral zone.We treated elderly patients suffering from distal radius fractures with metaphyseal comminution, using both volar fixed angle plate with or without augmentation with a hydroxyapatite bone graft substitute to investigate the benefit of augmentation for maintaining a fracture reduction. We evaluated the differences among radiographic parameters including palmar tilt, radial inclination, and ulnar variance on immediate postoperative and final follow-up radiographs to analyse the maintenance of the initial reduction.There were no significant differences between the two groups in terms of palmar tilt (P = 0.80) and radial inclination (P = 0.17); however, ulnar variance increased significantly in the group treated with a volar fixed angle plate without augmentation (P < 0.05).It might be useful to use a combination technique of a locking plate system and the hydroxyapatite bone graft substitute as augmentation to treat distal radius comminuted fractures in elderly patients.

Radius Fractures

(1) Background: Recently, surgical treatment of distal radius fractures has increased exponentially. Many locking plates’ fixation systems have been developed allowing a more stable reduction and early mobilization. Sometimes, open reduction and fixation of distal radius fractures may leave a residual bone loss requiring grafting. This retrospective study reports clinical and radiologic outcomes of distal radius fractures treated with xenohybrid bone grafting in order to assess (i) the safety of the investigated bone graft; (ii) its radiological integration and biomechanical performances, and (iii) clinical outcomes of the patients; (2) Methods: We performed a retrospective study on a cohort of 19 patients. Preoperative X-ray and CT scan were performed. The mean clinical and radiographical follow-up was two years. Safety of the xenohybrid bone graft was constantly evaluated. Clinical results were assessed through the DASH score and Mayo wrist score; (3) Results: No adverse reactions, infections, and local or general complication were related to the use of xenohybrid bone graft. The radiolucency of the xenografts suggested progressive osteointegration. No evidence of bone graft resorption was detected. All the patients reached consolidation with good to excellent clinical results; and (4) Conclusions: Clinical and radiological data demonstrated that xenohybrid bone grafting promotes new bone formation and healing in osteopenic areas caused by fracture reduction.
