Objectives/Interrogation: On the past decade, volar locking plate has become the most popular technique in the treatment of distal radius fractures (DRFs). Rigid fixation using these plates allowed for early mobilization, restoring the wrist function. However, DRFs with cortical comminution at the palmar side makes it difficult to stabilize to anatomical alignment only volar locking plate and that treatment often require additional methods. The object of this study is to assess that surgical fixation using artificial bone block suppressed reduction loss after the surgery by investigating the change of postoperative anatomical alignment of the distus radius.
Methods: A total of 153 patients with the open reduction and internal fixation were seen in this series between March 2013 and June 2018. All patients underwent proximal-type volar locking plate (stellar 2, HOYA technosurgical). Patients were excluded if they underwent fixation using external fixator or distal-type volar locking plate. Of these, 15 patients were added to artificial bone blocks.
10 patients, who belong to the same AO/ASIF classification as artificial bone block used group, were treated without bone block and compared as control group.
Imaging data using preoperative and postoperative radiographs were examined for radial alignment including radial tilt (RT), volar tilt (VT) and ulnar variance (UV) from 0 to 3 months after surgery.
Statistical analysis was done using a student-T test or ANOVA.
Results and Conclusions: At the population of patients by AO/ASIF classification, A3 was one (3), C2 was four (2) and C3 was ten (5). In Postoperative alignment of the cases using artificial bone block, the mean of RT was 21.5° (21.5°), VT was 12.2° (11.1°) and UV was -0.7mm (0.1 mm). In Postoperative reduction loss, the group with artificial bone block, RT was 0.6° (2.4°), VT was 1.3° (2.8°) and UV was 0.6mm (2.1mm). () showed control group.
In comminuted DRFs, especially palmar side comminution, those treatment still be challenging. This analysis indicates surgical fixation using artificial bone block is effective for preventing reduction loss after the surgery.
