Introduction Nonunions about the hip occur as a result of femoral neck, intertrochanteric, and certain subtrochanteric fractures. Treatment of a hip fracture nonunion allows for the choice between hip preservation or arthroplasty. The goal of this study was to examine outcomes of hip-preservation nonunion surgery Methods Patients who underwent hip preservation for a fracture nonunion of the femoral neck, intertrochanteric and subtrochanteric region to 1 cm below the lesser trochanter over a 10-year period were identified in our nonunion registry. Patients were followed for a minimum of 1 year. Functional outcomes were recorded at follow-up visits. For comparison regarding surgical and hospital outcomes, a group of 23 patients who underwent conversion total hip arthroplasties (cTHA) at the same academic medical center was reviewed. Quality measures such as length of stay, reoperation, and complications were collected. All statistics analysis utilized IBM SPSS 25 (Armonk, NY) Results Thirty patients who underwent 30 hip-preserving nonunion surgeries were analyzed and compared with 23 cTHA patients. Twenty-nine nonunions went on to heal (average time to union 6.3 months). There was improvement in functional outcome scores for the hip preservation group between baseline and latest follow-up ( p
