Distal Femur AO type 33 B – Surgical options, Results and Complications (including Hoffa’s fracture)

Abstract

Background: Distal femur AO type 33 B fractures are partial articular fractures. It also includes Hoffa’s fracture which is a relatively rare injury and requires always operative management even with no displacement. Approach to these fracture depend on the condyle involved also various quadriceps sparing approach like swashbuckler approach has been described in the literature. Surgical treatment of these fractures involves anatomical reduction, compression, stable fixation and early mobilization. Treatment modalities such as cancellous screws, pre-contoured anatomical locked plate, posterior condylar buttress plating, distal retrograde interlocking nailing, angled blade plate fixation, dynamic condylar screw may be considered. Each implant is associated with advantages and disadvantages which is discussed here.
