Abstract

[Indexed for MEDLINE] 4. Acta Orthop Scand. 1997 Dec;68(6):524-6. doi: 10.3109/17453679708999019. Seinsheimer's classification of subtrochanteric fractures. Poor reproducibility of 4 observers' evaluation of 50 cases. Gehrchen PM(1), Nielsen JO, Olesen B, Andresen BK. Author information: (1)Department of Orthopedics, Aalborg Hospital, Denmark. Gehrchen@rh.dk We examined the reliability of the Seinsheimer classification of subtrochanteric fractures of the femur. 50 consecutive anteroposterior and lateral radiographs were assessed independently by 4 observers twice with a 6-week interval. The interobserver variation was large; only 13 of the 50 fractures were classified identically by all 4 observers. The intraobserver variation showed identical classification in 26-37 of 50 radiographs. When assessing only whether the fracture was subtype 3A or not, the 4 observers agreed in 31 of 50 radiographs. We conclude that the Seinsheimer classification has no value in clinical practice. DOI: 10.3109/17453679708999019
