Clinical results of the brand new compression hip screw: Oblique locking hip screw

Introduction: Proximal femoral fractures are a common clinical concern. This study delves into the efficacy of a novel implant, the Oblique Locking Hip Screw (OLHS), in the treatment of these fractures.

Material & Methods: Our research covers trochanteric femoral fractures managed at our institution from April 2020 to September 2022. Key variables studied include fracture fixation, patient demographics, fracture classification, reduction techniques, surgical duration, postoperative surveillance, and clinical outcomes.

Results: Our dataset includes 119 trochanteric femoral fractures, with 67 treated using intramedullary nails and 52 with OLHS. A detailed comparative analysis of 51 OLHS cases, excluding one non-fragility fracture, was conducted. The patient cohort had an average age of 86.2 years, with 14 males and 37 females. Fractures were classified using the AO/OTA Classification, with 29 as 31A1 and 22 as 31A2. According to the Tang classification, 37 cases were type 1, while types 2, 3, 4, and 5 had 0, 7, 4, and 3 cases, respectively. Using the Baumgaertner criteria, 43 cases were 'good,' 6 'acceptable,' and 2 'poor.' By Chang criteria, 41 were 'excellent,' 9 'acceptable,' and 1 'poor.' Mean surgical time was 75.4 minutes, and mean follow-up was 12.3 months. Sadly, 3 deaths occurred within a month, and 2 more within 3 months post-surgery. Impressively, no implant failures or loosening were observed during follow-up.

Conclusion: Our comprehensive analysis reveals the potential of the Oblique Locking Hip Screw (OLHS) in addressing unstable trochanteric femoral fractures, potentially enhancing patient care and outcomes.
