Heterotopic Ossifications after Fractures of the Anterior Pelvic Segment: Overview of Morphology and Clinical Correlations

PURPOSE OF THE STUDY In certain patients after treated pelvic fractures, heterotopic ossifications can be observed in the area of pubic bone, which protrude ventrally, and often also laterally distally into surrounding soft tissues groin or even medially proximal thigh. These are shaped like sharp spikes various lengths, is why authors refer to them as spicules. some patients, these associated with pain. The aim this study was provide an overview morphology anterior segment pelvis discuss etiology their origin, further determine incidence, risk factors clinical significance spike-like ossifications. MATERIAL AND METHODS X-ray images for injuries between 2009 2018, whom radiological documentation available at least 12 months injury surgery were evaluated. Patients acetabular fractures combined not included study. Possible studied gender, severity injury, type fracture according AO / ASIF classification, concomitant bladder method treatment osteosynthesis pelvis. categorial data concerning spicule statistically evaluated using chi-square test 5% level significance. RESULTS group consisted 218 (121 women, 97 men) aged 13 92 years age (mean 54 years, median 55 years). Heterotopic occurred 21 (4 females, 17 males) 18 76 39 41 Significant ossification male sex (p = 0.0004), trauma (predominance spicules seen multiple 0.0024), unstable classification B C over A 0.0013), 0.0009) undergoing surgical < 0.0001), where all osteosynthesis. significant difference evident when comparing osteosynthetic material used (a increased incidence plate fixation compared screws used, p 0.0050). DISCUSSION described relatively common consequences but considered a major problem because they usually do produce any correlations. causes post-traumatic postoperative include effects high energy traumas, extensive procedures, prolonged artificial lung ventilation, post-infectious states complications treatment. CONCLUSIONS identified sex, fracture, treatment, use massive implants. Only effect partially influenced by performing less invasive techniques during injuries. Key words: complications, ossifications, trauma, urinary injury.
