Abstract:
PURPOSE:The management of irreducible, sagittally unstable peritrochanteric fractures presents a significant challenge due to the inability to achieve closed reduction using conventional techniques. This study introduces a novel minimally invasive technique leveraging the mechanical advantage principle with long, angled hemostatic clamps.
METHODS:A retrospective review was performed on 16 patients who sustained sagittally unstable peritrochanteric fractures and underwent a percutaneous hemostatic clamp leverage reduction procedure.
INCLUSION CRITERIA:(1) Preoperative confirmation of fracture type as peritrochanteric fracture; (2) Intraoperative imaging confirms the presence of sagittal plane displacement at the fracture site; (3) Age > 18 years.
EXCLUSION CRITERIA:(1) Open fractures, pathological fractures, and diabetes; (2) Long-term use of corticosteroids; (3) Patients with local skin or systemic conditions not suitable for surgery. Regular follow-ups at intervals of 6 - 8 weeks continued until evidence of bone consolidation was apparent in radiographic assessments. Evaluation of the alignment quality considered factors such as the re-establishment of the neck-shaft angle, the integrity of all cortical bone edges, and the rectification of any translational displacement, while the assessment of hip functionality was performed using the Harris scoring system. Statistical analysis of the relevant data was performed using SPSS 25.0 software.
RESULTS:The average age of these 16 patients was 56.8 years (ranging from 25 to 81 years), consisting of 8 males and 8 females. According to the AO/OTA fracture classification, the cohort included 13 cases of type 31A, 2 cases of type 32A, and 1 case of type 32C. The time from hospital admission to the day of surgery ranged from 3 to 11 days, with an average of 5.1 days. Closed reduction was successfully implemented in all 10 instances, negating the necessity for transition to open reduction procedures. The mean operative duration was 105.8 min (range 80 - 180 min). Satisfactory results of the quality of reduction were determined by comparison with the normal side. The average Harris hip score was 94.1 (range 87 - 99), and the fracture healing time was 4.2 months (3 - 6 months). Implant failure and malunion were not observed.
CONCLUSIONS:This study provides an alternative, minimally invasive technique for reducing sagittally unstable, irreducible peritrochanteric fractures. This technique holds the potential to manage complex fractures with the same efficacy as is typically reserved for simple and easily reducible fractures.
