Background. The domestic medical literature does not cover the issues of sacral dysmorphism fully enough. At the same time, the presence of this pathology is a factor of high risk of intraoperative complications in surgical treatment of fractures of the posterior parts of the pelvic ring.

OBJECTIVE

To establish the frequency of computed tomographic symptoms of sacral dysmorphism in patients with diseases and injuries of the lumbar spine and pelvis.

MATERIAL AND METHODS

The results of computed tomography of the lumbar spine and sacrum were analyzed in 118 patients aged 18—72 years who sought medical help for vertebrogenic and sacral pain syndrome and injuries to the lumbar spine and pelvis. Computed tomography was performed on a 128-slice «General Electric» device.

RESULTS

Of the 118 patients in the study cohort, 44 (37.3±4.4%) had radial symptoms of sacral dysmorphism. The frequency of pathology diagnostics was as follows: acute slope of the sacral wings — 31.8±6.9% of cases; mammillary processes S_I — 40.9±7.4%; residual disc S_I—S_II — 38.6±7.3%; deformed sacral openings S_I — 43.2±7.4%; “tongue in the groove” of the sacroiliac joint — 27.3±6.7%; “the sacrum is not recessed into the pelvis” — 25.0±6.5% of clinical observations.

CONCLUSION

The study achieved the set goal, namely, the frequency of computed tomographic symptoms of sacral dysmorphism in patients with diseases and injuries of the lumbar spine and pelvis was established. Timely diagnosis of sacral dysmorphism symptoms will allow trauma surgeons in a significant part of clinical observations to prevent possible severe intraoperative complications during surgical treatment of patients with unstable fractures of the posterior pelvic semiring.
