Abstract |
Objective Conservative treatment is a method for vertebral compression fracture management. Many patients suffer progressive vertebral collapse and an increase of local kyphosis during conservative treatment. The purpose of this study was to evaluate risk factors for progressive vertebral deformity in vertebral compression fractures treated conser- vatively.
Methods From January 2014 to June 2017, we retrospectively analyzed 31 patients with traumatic compression fracture at a single-level vertebrae that were treated conservatively(minimum 6-month follow-up). We measured initial and final vertebral height loss and local kyphotic angles. We assessed multiple variables; such as; age, sex, body mass index, presence of previous vertebral compression fracture history and osteoporosis; site, and presence of air cleft within a fractured vertebral body and middle column involvement; and shape of bone marrow edema.
Results Presence of air cleft within a fractured vertebral body was a risk factor for progressive vertebral body collapse (p=0.001). Presence of air cleft and middle column involvement were predisposing factors to increase of kyphotic angle (p=0.012, and 0.029, respectively).
Conclusion Close follow-up and active treatment may be needed when the presence of air clefts and middle column involvement in fractured vertebrae are noted upon initial examination. |
