Six-month functional and X-ray outcomes of distal radius fractures managed using multidirectional locking plates
Abstract
Distal radius fractures remain the commonest fractures in the human body. Developed countries have recorded increasing rates of these fracures.
Material and methods: The authors assess results of distal radius osteosynthesis procedures using the Aptus(R) Radius 2.5 mm (Medartis, Schweiz) system, consisting of 18 types of multidirectional, locking plates, designated for osteosyntheses and corrective osteotomies of the distal radius. The authors evaluate six- month results in 66 patients operated from January to September 2007.
All AO types of fractures were included in the study group.The mean age of the patients was 49.5 years. Results: According to X- ray, the mean healing time was 7 weeks. 6 moths following the procedure, the radius length was +0.4 mm (ranging from + 4 mm to - 4 mm), the radial inclination was 21° (ranging from 13°to 29°) and the palmar tilt of the articular surface was 7° (ranging from 0° to 10° of the palmar tilt).
The range of motion, compared to the other extremity, was as follows: palmar flexion 87.5%, dorsal flexion 91.5%, radial duction 90.5%, ulnar duction 88.2%, pronation 98.1% and supination 94.3%. The mean grip strength reached 85% of that of the contralateral extremity.
Discussion: Fragment-specific fixation using the Aptus radius system, provides enough stability to prevent secondary loss of correction. Functional and radiological outcomes were similar to those with other types of locking plates.
The results obtained from this study correspond to data presented in other recent studies assessing multidirectional locking plates. Conclusion: Central, targeted fixation of the fracture fragments and introduction of locking screws provide stability, which minimizes duration of additional fixation and facilitates early rehabilitation.
It can be used for osteosynthesis of all types of fractures according to AO classification
