Patients were operated on within 48 hours of admission. Anteroposterior and lateral radiographs were examined for the tip-apex distance and femoral shortening. Potential complications were looked for, including implant migration, cut-out, loosening, or breakage. Functional outcome was based on the Parker mobility score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>The 30-day and one-year mortality rates were 5% and 20%, respectively. At the one-year followup, 81 patients were available, and all fractures had healed without varus deformity. The mean tip-apex distance was 14.1 (range, 5.7\u201331.1; SD, 4.3) mm. The mean femoral shortening was 4.9 (range, 0\u201320.2; SD, 4.8) mm. The mean Parker score decreased to 3.8 at one-year follow-up from 5.9 before injury (p&lt;0.001). There was one loss of fixation secondary to a nontraumatic subcapital fracture at 3 months, for which a bipolar hemiarthroplasty was performed.<\/jats:p>\n                  <\/jats:sec>\n
