Femoral neck fractures secondary to renal osteodystrophy. Literature review and treatment algorithm.

Pathological fractures after minor trauma in osteopenic patients are not uncommon, but fractures due to hypocalcemic convulsions in patients with renal insufficiency are relatively rare. Though similar cases have been reported in the literature, this type of fracture is still an unusual condition. The complex underlying pathophysiological mechanisms and the poor bone mineral density signify the employment of specific hardware and a different treatment approach, especially in young adults, where the salvage of the femoral head is of utmost importance. The aim of this review is to examine the specific features of the femoral neck fractures in young individuals who suffer from renal osteodystrophy and the treatment algorithm should be followed. The patient's age, the uremic condition, the skeletal maturity and the bone properties in renal osteodystrophy are examined in relation to the priorities in osteosynthesis methods. A conclusive treatment algorithm is proposed where all the relevant parameters are incorporated.
