Volar locking and angular stability plate for treatment of comminuted scaphoid fractures: a case series of 44 cases.

BACKGROUND

The primary method employed worldwide for the treatment of scaphoid fractures is screw fixation. However, in unstable and comminuted fractures, percutaneous fixation could produce complications due to technical challenges, such as improper axis positioning, inaccurate screw length measurement, intra-articular screw penetration, and impingement. Alternative open approaches for the surgical management of scaphoid fractures have been proposed, and in recent years, a new specific volar locking plate for the treatment of scaphoid fractures has been developed. This study aims to present the outcomes of this technique applied to 44 patients with unstable and comminuted fractures of the scaphoid.

AIMS

The purpose of the study is to verify the effectiveness of the volar plate in the treatment of comminuted scaphoid fractures and the necessity for plate removal when consolidation has occurred.

METHODS

Between January 2021 and March 2023, a specific volar locking plate for the treatment of scaphoid fractures was used in 44 patients. A retrospective study was conducted involving all patients, consisting of continuous clinical and radiographic assessments, functional evaluations (using QuickDASH and MHQ), and patient satisfaction surveys.

RESULTS

All patients achieved clinical and radiographic recovery. However, the plate can impinge with nearby structures and should be removed once the fracture is consolidated. After plate removal, further improvement in range of motion was observed.

CONCLUSION

The plate and screws system is a viable and appropriate method of osteosynthesis in the treatment of unstable and comminuted recent fractures occurring in the middle third of the carpal scaphoid.
