fa Nuclear medicine Research (Original) Calcaneal fracture accounts for 2% of all fractures and is the most common tarsal fracture. Regarding this, the present study was conducted to determine and compare the surgical and non-surgical treatments in adult patients with calcaneal fractures in terms of outcomes, patients&rsquo; satisfaction level, and complications. This clinical trial was conducted on 63 patients with intraarticular fractures of calcaneus referring to the educational centers of Mazandaran University of Medical Sciences, Mazandaran, Iran, to assess the surgical and non-surgical methods. The patients&rsquo; satisfaction level with the treatment was estimated based on the visual analog scale. In addition, pain, function, and organ alignment were evaluated by using the American Orthopedic Foot and Ankle Society Hind Foot Score (AOFAS). Out of the 63 patients, 26 (41.3%) and 37 (58.7%) cases were in the surgical and non-surgical groups, respectively. The mean score of AOFAS was obtained as76.35&plusmn; 17.19 (out of 0-100) with the minimum and maximum values of 22 and 100, respectively. The results revealed no significant difference between two treatment groups in terms of mean AOFAS. As the findings of the present study indicated, the surgical and non-surgical methods in patients with Essex grades III and IV calcaneal fractures did not affect their satisfaction after treatment and improvement. Therefore, given the higher number of the surgical treatment complications, it is recommended to adopt the non-surgical treatments.<br> &nbsp; Surgical treatment, therapeutic complications, Intra-articular calcaneal fractures 36 40 http://tbsrj.mazums.ac.ir/browse.php?a_code=A-10-3412-2&slc_lang=fa&sid=1 Mohammad Hossein Kariminasab 100319475328460028683 100319475328460028683 No Orthopedic Research Center, Mazandaran University of Medical Sciences, Sari, Iran Mokhtar Esmailnejad Ganji 100319475328460028684 100319475328460028684 No Orthopedic Research Center, Mazandaran University of Medical Sciences, Babol, Iran Masoud Shayesteh Azar mshayestehazar@yahoo.com 100319475328460028685 100319475328460028685 Yes Orthopedic Research Center, Mazandaran University of Medical Sciences, Sari, Iran Mehran Razavi Pour 100319475328460028686 100319475328460028686 No Orthopedic Research Center, Mazandaran University of Medical Sciences, Sari, Iran Salman Ghafari 100319475328460028687 100319475328460028687 No Orthopedic Research Center, Mazandaran University of Medical Sciences, Sari, Iran Mirdavod Mirhosseini 100319475328460028688 100319475328460028688 No Orthopedic Research Center, Mazandaran University of Medical Sciences, Sari, Iran Iman Sadeghian 100319475328460028689 100319475328460028689 No Orthopedic Research Center, Mazandaran University of Medical Sciences, Sari, Iran
