“…In our centre, we tend to treat the calcaneal fractures nonoperatively with a below knee cast. We do not routinely request for Computer Tomography Scan 6,7 . For this study, we used the Essex-Lopresti classification 2 , which is based on the plain radiographs of the calcaneum.…”

I In nt tr ro od du uc ct ti io on n: : Treatment of calcaneal fracture is still controversial and indication for surgery is not well established. We are reporting the mid term outcome of calcanel fractures treated conservatively. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Patients admitted with calcaneal fractures from 1st November 2002 till 31st December 2004 and were treated conservatively were included in this study. The fractures were grouped according to Essex-Lopresti classification and their outcomes were assessed with the Maryland foot score. We also looked at time to weight bearing and returning to occupational activity. R Re es su ul lt ts s: : Forty-four patients were included for evaluation. Patients with extraarticular calcaneal fractures had significantly higher rating scores compared to those with intraarticular fractures (98.2 and 88.8 respectively, with a p value = 0.0001). Generally, both group of patients had a good clinical outcome. 18 of the 44 patients (41%) started partial weight bearing before or at 6 weeks and 31 patients (72%) were able to start full weight bearing by 12 weeks. 31 patients (72%) were back to work 12 weeks after the injury. C Co on nc cl lu us si io on n: : Conservative management for calcaneal fractures is an acceptable mode of treatment with satisfactory functional outcome.

“…Computed tomography is essential for preoperative evaluation of intra-articular calcaneal tractures.l'' [7][8][9][10][12][13][14][15][16][17][18][19] Coronal CT images help evaluate superior posterior facet disruption, sustentaculum tali depression, peroneal or flexor hallucis tendon entrapment, and widening and loss of calcaneal height. Axial CT images show disruption of the inferior part of the posterior facet, calcaneocuboid joint involvement, and widening of the calcaneus."…”

A Pitfall of Coronal Computed Tomographic Imaging in Evaluation of Calcaneal Fractures

et al. 1996

Computed tomographic (CT) coronal images of the posterior talocalcaneal joint were compared with lateral radiographic views and intraoperative findings in 35 patients with 36 intra-articular calcaneal fractures. The severity of articular incongruity and rotational displacement of the posterior facet fragment were not well appreciated in coronal CT images of nine patients, although Bohler and Gissane angles were significantly decreased in lateral radiographs. This disparity between the radiographic and coronal CT scans can be explained by the intraoperative finding of rotation of the fractured central or lateral portion of the convex posterior calcaneal facet along a horizontal axis in the coronal plane.

“…The subtalar joint, because of its complexity, has historically been difficult to assess both clinically and radiographically. This is demonstrated by the numerous studies that have been dedicated to clinical evaluation, 5,6,8,20,21 kinetic evaluation, 24,25,28,29,31,32,37 and radiography 2,4,9,11,14,17,22,27,33 of the subtalar joint.…”

“…Many authors have indicated that computed tomography (CT) is superior in assessing both normal and pathologic conditions of the subtalar joint. 4,11,17,27,33,36 It is the authors' understanding that there has been little work with CT when looking at subtalar motion. CT has superior ability to diagnose subtle fractures 4,11 and arthritis, 27 and we believe that it may be useful to help in understanding subtalar motion as well.…”

The purpose of this study was to compare subtalar motion measured externally (representing clinical assessment) with subtalar motion measured by computed tomography (CT), in normal individuals. Ten recreationally active subjects (20 lower extremities), aged 20 to 35 years with no lower extremity pathologic condition, were involved in the study. External subtalar inversion and eversion was assessed using a goniometer. By overlaying CT images of the subtalar joint in inversion and eversion on neutral images, angular subtalar motion was measured directly. Subtalar motion measured by CT ranged from 5 degrees to 16 degrees (mean, 11 degrees). External subtalar motion ranged from 39 degrees to 54 degrees (mean, 46 degrees), overestimating CT measurement of subtalar motion by approximately three-fold. This discrepancy is probably secondary to soft tissue motion and talocrural motion that is not isolated from subtalar motion at clinical examination. This solidifies our belief that clinical assessment of subtalar motion should no longer be used to determine or document the measurement of subtalar motion.
