Femoral head fractures result from high-energy trauma and may be associated with posterior dislocation of the hip joint. An appropriate surgical approach is essential for improving clinical outcomes and preventing complications. This study aims to compare the clinical efficacy of the modified Smith-Peterson (mS-P) approach and Ganz surgical dislocation (GSD) approach in the treatment of Pipkin I fractures. We conducted a retrospective analysis of patients diagnosed with Pipkin I fractures at Pidu District People's Hospital from June 2010 to May 2020. Of these, 11 cases were treated with the mS-P approach and 12 cases were treated with the GSD approach. All patients were followed for 12-55 months, with a mean duration of 37.7 months. Basic demographic information, perioperative-related records, postoperative complications, and outcomes at the final follow-up were compared. Functional evaluations included the Thompson-Epstein Score, the Modified Harris Hip Score (MHHS), and the Vail Hip Score (VHS). Overall, 21 patients were included in the study. We found that the mS-P approach was associated with a smaller incision, shorter operative time, and reduced intraoperative blood loss compared to the GSD approach (P
