Abstract
Background: The most frequently broken tarsal bone is the calcaneum. Even if the rehabilitation process can take a while and the treatment is challenging, the results are still very unexpected. As a result, calcaneal fractures place a significant socioeconomic strain on society. As a result, we looked for a factor, such as Bohler's angle, that we might link to the functional result of patients with intra-articular calcaneal fractures.
Method: A calcaneum intra-articular fracture was present in 40 individuals. X-rays and CT scans were used to assess each patient before to surgery. With the use of a goniometer, Bohler's angle was manually determined on the lateral radiograph, and a record was created for future use. All patients were treated using open reductions and intermaxillary fixation with a plate, accompanied by or without bone transplant, according to a randomization process. Following surgery, Bohler's angle was assessed at follow-up visits at 2, 4, and 6 weeks as well as 2, 4, and 6 months. The American Orthopedic Foot and Ankle Score (AOFAS) was used to evaluate the patient's functional recovery at least 5 months following the injury.
Results: Our analysis of 40 calcaneal fractures demonstrates that there was a statistically significant distinction in the functional outcomes of patients according to the surgically corrected Bohler's angle. Less comorbidities and statistically significant better outcomes were seen in surgical calcaneus fractures when Bohler's angle was restored within normal bounds. The benefit of autologous bone transplant in restoring calcaneal elevation and anatomic minimization was also proven by our research.
Conclusion: We recommend using Bohler's angle as a key to achieving outstanding results in displaced calcaneal fractures as well as the use of autologous bone graft in attaining and maintaining normal Bohler's angle in light of the great results gained with Bohler's angle rehabilitation.
