Background: The goal of the ongoing research aimed mainly to assess clinical and radiological outcomes ‎of the mini-open sinus tarsi surgical technique in reduction and fixation management of intra-articular ‎displaced calcaneal bone fractures, which are frequently caused by high-energy trauma. Methods: 23 ‎participants with intra-articular displaced calcaneal bone fractures were managed surgically using mini-‎open sinus tarsi technique. Plain X-ray films included lateral, anteroposterior, and axial heel views for all ‎patients. CT scan was done to the studied participants preoperatively. The classification of fractures ‎according to Sanders was II and III. Results: Acording to AOFAS score 6 cases were having excellent ‎results, 15 cases were good, one case was fair and one case with poor result. Nine patients responded no ‎pain, 12 patients complained mild pain, one patient presented with daily moderate degree of pain while ‎only one patient complained from severe pain. Conclusion: the mini-open sinus tarsi surgical approach is ‎valuable for reduction and fixation of intra-articular calcaneal bone fractures. It is highly efficient with in ‎Sander's II & III calcaneal fractures.‎
