Objectives:
This study aims to evaluate the mid-term functional and radiological outcomes of magnesium-based screws in the treatment of scaphoid fractures.
Patients And Methods:
Between February 2015 and February 2018, a total of 21 patients (18 males, 3 females; mean age: 28.5±5.8 years; range, 19 to 39 years) with acute scaphoid waist fractures who underwent fracture fixation with biologically degradable magnesium-based compression screws were retrospectively analyzed. Fractures were classified according to the Herbert and Fisher classification. The absence of pain on palpation and painless active range of motion were accepted as the signs of union.
Results:
The mean follow-up was 43.3±5.3 (range, 36 to 52) months. According to the Herbert and Fisher classification, nine patients had type B1 and 12 patients had type B2 scaphoid fractures. Union was achieved in all cases. The mean time to union was 11.2±1.5 (range, 9 to 14) weeks. The mean grip strength, flexion, and extension were 43.57°, 73.57°, and 76.43°, respectively. The grip strength, pinch strength, and range of motion of the operated side were evaluated at the final follow-up visit and compared with the contralateral side (control group). No complication occurred. Any screw was not removed.
Conclusion:
Magnesium-based compression screws can be safely used for acute scaphoid fractures considering their favorable functional and radiological results.
