            [0] => Introduction: The rate of converting hemiarthroplasties to total hip arthroplasties for femoral neck fractures is notably higher compared to other conditions. This study aims to explore the principal reasons for conversion, the surgical methods utilized, and their outcomes both short-term and long-term.

Materials and Methods: In a retrospective review spanning ten years, this study looks into 20 cases where hemiarthroplasties, initially placed for femoral neck fractures, were later converted to total hip arthroplasties. With an average monitoring period of 28 months, the study evaluated the conversion's indications, the surgical techniques adopted, and the subsequent results.

Results: Including 40 participants with an average age of 75 years, pain was the primary symptom necessitating revision. The leading causes for conversion were identified as aseptic loosening (35%), acetabular erosion (25%), and instability (20%), alongside six instances of periprosthetic fractures. Preoperatively, the average Postel-Merle d'Aubigné score significantly improved from 96 to 15 postoperatively, notably in mobility, even though 60% were non-ambulatory prior to surgery. Cemented implants were used in all cases, with 35% requiring bone grafts. The complication spectrum was limited, including an iatrogenic femur fracture, a greater trochanter fracture, a posterior acetabular wall fracture, and one late total hip dislocation.

Discussion: Hemiarthroplasty, often preferred for older femoral neck fracture patients, reduces acetabular shear stress and allows easier conversion to total hip replacement absent femoral stem loosening. Conversion indicators include instability, loosening, erosion, periprosthetic fracture, acetabular protrusion, and infection. Comparative studies have indicated higher failure rates for hemiarthroplasty conversions than for primary total hip replacements.

Conclusion: The prevalence of converting hemiarthroplasties to total hip replacements is on the rise, predominantly due to aseptic loosening and instability. Revision surgery poses more significant challenges than primary arthroplasty, emphasizing the importance of meticulous operative planning.
