Abstract: | Sixteen consecutive patients with cutout of a lag screw of a dynamic hip screw fixation in an intertrochanteric fracture
were treated with reinsertion of a lag screw, bone cement supplementation in the neck-trochanter, and subtrochanteric valgus
osteotomy. Postoperatively, patients were permitted to ambulate with protected weight-bearing. Fourteen patients were followed-up
for at least 1 year (median 2 years; range 1–3 years), and all had a solid union. The union period took a median of 5 months,
with a range of 3–7 months. Usually, union of an intertrochanteric fracture was faster than that of subtrochanteric osteotomy
(P < 0.01). There were no complications of wound infection, loss of reduction, cutout of a lag screw, or osteonecrosis of the
femoral head. From clinical and theoretical considerations, we conclude that despite cutout of a lag screw of a dynamic hip
screw fixation being difficult to treat, out technique still can provide an excellent outcome. Therefore, we strongly recommend
its wide use.
