Abstract
Background: Calcaneus is a spongy cancellous bone with rich blood supply , its fracture heals more rapidly providing no occurrence of infection and soft tissue injury around ,no gross malposition of fragments. The associated pain leads to a major impairment in life quality. The aim of treatment for calcaneal fractures is the decrease of pain and rebuilding of walking ability for patients with normal foot shape and the ability to wear normal foot wear. To reduce complications, a minimally invasive technique for the treatment of displaced intra-articular fractures of the calcaneus was preferred to use.
 The purpose of this study was to determine whether the closed reduction and percutaneous K. wire fixation of displaced intra-articular calcaneal fractures results in better functional outcome at a minimum one year follow up after the injury compared with those after non-operative management.
 Methods: One hundred and eleven displaced closed intra-articular calcaneal fracture in 105 patients (six were bilateral) were seen at the orthopedic department of Al-Kindy teaching hospital and Shaih Zaid hospital , only 45 cases included in this study and prospectively evaluated with an average follow-up time of minimum of one year (1–3years follow-up). For radiographic evaluation, plain radiographs and CT scans were obtained. The Maryland Foot Score was used for clinical estimate. Sanders type II, III and IV fractures were diagnosed.
 Results: The incidence of subtalar arthritis was correlated with the severity of fracture. Böhler’s angle was restored in 70.1% (47 of 67) of the cases. The majority (77.7%) of patients were content with their treatment result. The rate of significant complications was 6.5%.
 Discussion: Percutaneous K. wire fixation of displaced intra-articular calcaneal fractures presented minimally invasive technique which showed comparable results with a low rate of serious complications and is a viable alternative for the treatment of intra-articular, dislocated calcaneal fractures.
 Conclusions: the functional results after K. wires fixation of displaced intra-articular calcaneal fractures were better than those after non-operative care.
Highlights
A fracture of the calcaneus permitted healing in an unsuitable anatomical location leads to static and dynamic faults of the whole foot with resulting partial load bearing capacity and walking ability [1, 2]
We treated 45 patients with closed displaced intra-articular calcaneal fracture at Al-kindy teaching hospital and we found that; The left side was more involved (28 cases 62.2%), than right foot (17 cases 37.8%) .tab

Summary
A fracture of the calcaneus permitted healing in an unsuitable anatomical location leads to static and dynamic faults of the whole foot with resulting partial load bearing capacity and walking ability [1, 2]. The related pain leads to a important impairment in the life quality. Controversy remains with respect to whether displaced intra-articular calcaneal fractures should be treated operatively or conservatively[11,12,13,14,15]. Displaced intra-articular calcaneal fractures were treated conservatively, as predictable operative reduction and fixation were not possible [12, 13, 16]. Operative reduction became more standard as fracture care improved [17,18,19,20] Reviews on this subject, have failed to demonstrate unquestionable superior results of a single approach to the treatment of displaced intra-articular calcaneal fractures .
