Aim: The aim of the study was to investigate the efficacy of the multidetector CT scan in the diagnosis and classification of pelvic and acetabular fractures.

Material and Method: 41 patients, 13 women and 28 men suspect for acetabular or pelvic fracture were examined. Patient’s ranged from 15 to 72 years. Fracture classification was based in that of Letournel and Judet. Examination was performed with a Multidetector CT scanner (Phillips-Brilliance), withnmultiple detectors and thin slices of 2 mm Multilevel and three dimensional reconstructions were performed.

Results: in 15 patients suspects for pelvic or acetabular fracture in plain xray, the CT scan was negative for revealing a fracture. In the rest 26 patients, there were 19 fractures of the anterior column, 4 fractures of the posterior column, 11 acetabular fractures and 7 sacral fractures. All the fractures were detected at the horizontal plane. MPR views were offered additional information for the sacral and acetabular fractures. In 7 patients the fractures diagnosed only after the CT scan was performed. In these patient plain x-rays were negative for fracture. In 6 patients the treatment algorithm was modified, based on CT scans findings

Conclusion: We believe that MDCT is an appropriate as well as an essential method in patients suspects for pelvic or acetabular injuries. MPR and three dimensional reconstructions are very helpful in revealing the personality of the fracture element very important for classification purposes as well as for planning treatment.

Aim: The aim of the study is to evaluate the usefulness of the MDCT scan in the diagnosis of calcaneal fractures and its use in the surgical treatment

Material. 112 calcaneal fractures were examined with a MDCT scan (slices one to two mm, pitch 1.5) with multilevel reconstruction as well as three dimensional reconstruction. The fractures were classified according to Munich classification system. Findings that were evaluated were the involvement of the subtalar joint, the number of fragments of the posterior facet and the extent of displacement.

Results: There were 85 intraartiular fractures and 27 extraarticular. 32 fractures were of type I according to Munich classification system (extraarticular without displacement). 15 fractures were of type II (extraarticular with some displacement). 2 fractures were of type III (intraarticular without displacement). 27 were of type IV (two fragments). 19 were of type V (with free fragments in the joint and 17 were type VI (more than four fragments).

Conclusion: The above mentioned radiological method of evaluating calcaneal fractures offers a quick diagnosis since it can depict the fragments and its displacement very accurately. Furthermore this method permits a very precise preoperative planning for the surgical treatment of these injuries

Aim: The aim of this study is to evaluate the efficacy of the multidetector CT scan in shoulder fractures and to correlate these findings with those of plain x-rays.

Material and Method: A 105 patients with shoulder fracture were examined with a multidetector CT scanner after the acute injury. There were 64 male and 41 female with an average age of 52 yrs (range 16–95 yrs). The examination was performed with a CT PHILIPS BRILLIANCE, and six groups of detectors were used, with thin slices (1.6–2 mm). MPR and three dimensional reconstructions were performed.

Results: The mechanism of injury was fall during walk in 66 patients, fall from a height in 11 patients, and road traffic accident in 28 patients. They were detected 210 fractures at the shoulder region. A 135 fractures were located at the proxd imal end of the humerus, 75 at the scapula, in 95 out of 105 patients. In 10 patients with a comminuted fracture of the upper end of the humerus, the exact number of fragments as well as the precise location of them was not accurately assessed with plain xrays. MDCT control with multilevel anasynthesis and three dimensional reconstruction improved the understanding of the anatomic orientation in complex fractures and fractures–dislocations and in detection of subluxation of the fragments of the shoulder headin four part fractures in two patients.

Conclusion: Our results would orient us for using the MDCT scan in patients with acute shoulder injury, especially in cases with comminuted fractures, because it is better assessed the place, the orientation and the displacement of fragments, which are not easily identified in plain xrays. Furthermore, these reconstructions improve the preoperative planning in those patients
