Abstract
Background: Calcaneal fractures account for 60% of tarsal fractures, with displaced intra-articular fractures requiring surgical intervention. The optimal surgical approach remains debated between the Sinus Tarsi Approach (STA) and Extensile Lateral Approach (ELA). This study compared clinical, radiological, and functional outcomes of both techniques to guide surgical decision-making.
Methods: A prospective comparative study was conducted at Shri Guru Ram Rai Institute of Medical and Health Sciences, Dehradun, over 18 months. Sixty patients with Sanders Type II and III calcaneal fractures were randomized into two groups (n=30 each) receiving either STA or ELA. Preoperative assessments included radiological evaluation and CT scans. Follow-ups at 6, 12, and 24 weeks assessed pain (VAS score), functional recovery (AOFAS and Maryland Foot Scores), radiological alignment (Böhler and Gissane angles), wound healing, and complications. Statistical analysis used SPSS with p<0.05 considered significant.
Results: The STA group demonstrated significantly shorter operative time (65.5±10.2 vs 85.3±12.4 minutes, p=0.001), reduced hospital stay (4.2±1.1 vs 6.5±1.3 days, p=0.001), and better pain control at 24 weeks (VAS 0.5±0.6 vs 1.2±1.1, p=0.001). Wound complications were lower in STA (0% dehiscence vs 8.3% in ELA). Both approaches achieved significant radiological improvements, with ELA showing marginally better Böhler (28.5±3.2° vs 27.8±3.1°) and Gissane angles (130.2±3.8° vs. 128.5±3.6°). Functional outcomes favored STA, with superior AOFAS (91±4.9 vs 90±5.5) and Maryland Foot Scores (90±4.3 vs 89±5.2) at 24 weeks (p=0.001). Earlier weight-bearing (8.2±1.5 vs 10.5±1.8 weeks) and faster return to work (12.5±2.1 vs 15.2±2.5 weeks) were observed with STA (p=0.001).
Conclusion: While both approaches effectively manage calcaneal fractures, STA offers superior outcomes in operative efficiency, pain management, wound healing, and functional recovery. ELA remains preferable for complex fractures requiring extensive exposure.
