RESUMO
Involvement of posterior elements of the spine in spinal tuberculosis is rare. We report a case of a 56-year-old woman who presented with asymptomatic tuberculosis of the tenth and eleventh costotransverse joints. The latter was discovered with a CT scan made to look for a pulmonary embolism. Magnetic Resonance Imaging (MRI) showed liquid in the costotransverse joints with a paravertebral abscess. The patient was managed conservatively. Although rare, posterior tuberculosis of the spine should be known by spine surgeons. MRI is the key to the diagnosis. Conservative treatment is the standard treatment, and surgery is reserved for patients with neurological deficit.
RESUMO
PURPOSE: To compare the outcomes of the Kocher-Langenbeck reduction and fixation of the posterior structures of the acetabulum between 3D printing technique and conventional technique. METHODS: Forty-three patients who sustained fractures of the posterior part of the acetabulum were randomly assigned to two groups: 3D printing (G1; n = 20) and conventional technique (G2; n = 23). The surgical time, intra-operative blood loss, differences between pre-and post-operative haemoglobin, universal functional and radiographic scores, and complications were compared between the groups. The minimum follow-up was 18 months. RESULTS: The average operating time (120.75 min) and intra-operative blood loss (244 ml) were lower in G1 than in G2 (125.87 min and 268.7 ml, respectively; p = 0.42, p = 0.1, respectively). The difference between the pre- and post-operative haemoglobin was 1.71 g/dl in G1 and 1.93 g/dl in G2 (p = 0.113). Post-operative complications occurred more frequently in patients in G2 (34.7%) than in patients in G1 (15%), though these differences were also not significant (p = 0.6). The radiographic result was satisfactory in 16 patients (80%) in G1 and 18 patients (78.26%) in G2 (p = 0.5). The clinical result was satisfactory in 15 patients (75%) in G1 and in 17 patients (73.9%) in G2 (p = 0.6). CONCLUSIONS: No significant differences were found in terms of surgical time, overall complications, and radiographic or functional outcomes between 3D printing and the conventional technique.
