Persistent femoral neck non-union despite valgus intertrochanteric osteotomy: Relevance for secondary cam-type impingement

Blog Article

Valgus intertrochanteric osteotomy is a well-established treatment in delayed union of femoral neck fractures as it converts shear forces into compression forces.Non-union of the femoral neck fracture may persist following valgus intertrochanteric osteotomy, and secondary femoroacetabular impingement (FAI) may Joint / Bone Support be a contributing factor.Case: We report one case of persistent femoral neck non-union after treatment by valgus intertrochanteric osteotomy with concomitant secondary Urinals cam-type impingement from fracture callus as a possible cause for ongoing insufficient healing.Healing was achieved following surgical hip dislocation with corrective osteochondroplasty of the femoral head-neck junction.Two-year follow-up shows good clinical and radiological outcomes.

Conclusion: In ongoing non-healing of femoral neck fractures following valgus intertrochanteric osteotomy, secondary cam impingement from fracture callus must be excluded.
