The bone trauma and soft-tissue injury classification system in total hip arthroplasty (BOSTI Hip).

Aims: The primary objective of this study was to develop a validated classification system for assessing iatrogenic bone trauma and soft-tissue injury during total hip arthroplasty (THA). The secondary objective was to compare macroscopic bone trauma and soft-tissues injury in conventional THA (CO THA) versus robotic arm-assisted THA (RO THA) using this classification system.

Methods: This study included 30 CO THAs versus 30 RO THAs performed by a single surgeon.
