[The atypical C-malleolar fracture]

Area of Science:

• Orthopedic Surgery
• Traumatology

Background:

• Ankle fractures are common injuries requiring precise reduction and stable fixation for optimal outcomes.
• The Weber classification system categorizes ankle fractures based on the fibular fracture's location relative to the syndesmosis.
• Open reduction and internal fixation are often necessary for intra-articular ankle fractures.

Purpose of the Study:

• To define, diagnose, and present treatment outcomes for atypical Weber type C ankle fractures.
• To differentiate atypical type C fractures from typical Weber classifications.
• To analyze a specific subset of ankle fractures characterized by medial malleolus involvement and syndesmotic disruption without fibular fracture.

Main Methods:

• Review of over 1000 ankle fractures treated between 1978 and 1992.
• Identification and analysis of 9 cases presenting with atypical Weber type C fracture patterns.
• Evaluation of diagnostic methods, surgical interventions, and patient results for these specific fractures.

Main Results:

• Atypical type C fractures were identified in 9 patients within a cohort of 72 Weber type C fractures.
• These atypical fractures feature a medial malleolus fracture combined with tibiofibular ligament injury, but lack a fibular fracture.
• The study presents the definition, diagnostic criteria, treatment strategies, and outcomes for these specific ankle injuries.

Conclusions:

• Atypical Weber type C ankle fractures represent a distinct injury pattern requiring specific diagnostic and therapeutic considerations.
• Accurate identification and management are crucial for achieving favorable results in these complex ankle fractures.
• This study contributes to understanding and managing a less common but significant variant of ankle fractures.
