Can Screw-only fixations of ACPHT acetabular fractures enhance stability as the standard buttress plate fixation provides?
Abstract: Background: Of acetabular fractures, anterior column posterior hemi-transverse(ACPHT) fractures commonly occur after a fall onto the hip in elderly population. When displaced in these fractures, open reduction and internal fixation using plate and screws is usually required to achieve good functional outcomes. The open procedures, however, involve high complication rates due to surgical invasion; therefore, percutaneous techniques by screw-only constructs have been advocated to minimize these complications.
