“…3 Calcaneal trabecular bone architecture. According to Diard et al [7] the calcaneal trabecular bone architecture is described by six trabecular bone groups. In terms of functionality, the thalamic group (area 1) is the most important one, characterised by a trabeculation arising from the subchondral bone of the subtalar joint spreading on the cortex of the posterior tuberosity with a concave anteroinferior curve.…”

Purpose Tumours of the calcaneus are exceedingly rare and the correct diagnosis is often missed. X-rays are the standard clinical examination tool and therefore we wanted to discover whether X-rays alone were a sufficient diagnostic tool for these tumours. Diard's classification was applied to define whether different types of lesions were characteristically distributed in the bone and in addition we analysed whether type and/or duration of symptoms were possible indicators of malignancy. Methods Ninety-two patients' files (59 men and 33 women) were retrospectively reviewed. Seventy-five patients with a mean age at surgery of 28 years (range five to 78) were surgically treated. Parameters analysed were sex, age at surgery, side, type and duration of symptoms, tentative diagnosis, biopsy prior to surgery, operative procedure, recurrence rate, revision and localisation of the lesion according to Diard. For each lesion the first documented radiological diagnosis andin cases of malignancy-Enneking's classification was applied.Results Discrepancies between the radiological and definitive histological diagnosis occurred in 38 (41 %) of 92 cases. In eight (osteosarcoma n =5, Ewing's sarcoma n =2, metastases n =1) of 17 malignant cases radiological examination initially gave no evidence of malignancy, resulting in an unplanned excision ("whoops procedure") in three cases of osteosarcoma. Applying Diard's system trabecular area 6 (radiolucent area) was highly affected in 64 (80 %) of 80 investigated plain Xrays, whereas areas 1 and 5 were affected in nine (11 %) and 16 (20 %) cases only. Conclusions In each case of an osteolytic lesion of the calcaneus a malignant tumour must be ruled out, and thus preoperative plain X-rays in two planes alone are not sufficient and should therefore be followed by magnetic resonance imaging. Applying the Diard system different types of lesions are not characteristically distributed in the bone. Increasing pain for more than ten days without previous trauma should always justify further examinations.

This article focuses on nonspinal fragility or insufficiency fractures. Fragility fractures occur when normal levels of energy are applied to weakened bone, and they normally represent spontaneous fractures or traumatic fractures from minimal energy trauma that would not normally result in fracture in healthy people. This is the case in osteoporosis, where there is reduction of bone mass as well as loss of normal trabecular architecture leading to changes in structural characteristics that compromise biomechanics.The prevalence and most common locations, as well as clinical and diagnostic aspects, of nonspinal fragility fractures are presented. Osteoporosis is highly prevalent and can have different causes. The most common ones are primary, such as postmenopausal and senile osteoporosis, and secondary to several causes.Clinically, patients with insufficiency fractures present with pain, in many cases severe, and usually no history of trauma or eventually a history of minor trauma, such as a fall from standing height. If some cases, when these fractures are not displaced, detection is a challenge. In other cases, due to their location and equivocal features, differential diagnosis with malignancy has to be made. Radiographs, magnetic resonance imaging, multidetector computed tomography, positron emission tomography-computed tomography, and radionuclide scans have diverse roles in the diagnosis of insufficiency fractures.
