Transpedicle body augmenter for vertebral augmentation in symptomatic multiple osteoporotic compression fractures

Pain location is associated with fracture type in acute osteoporotic thoracolumbar vertebral fracture: a prospective observation study

OBJECTIVE

This study investigated the relationship between pain location and fracture type in the patients with acute osteoporotic vertebral fracture (OVF).

DESIGN

A prospective observation study.

SUBJECT

A total of 306 patients with acute OVF were included.

METHODS

The site of pain of each patient was recorded, and the patients were divided into pain at fracture site group (group 1) and pain at non-fracture site group (group 2). The fracture type was classified into four types: type I, upper endplate type; type II, central type; type III, lower endplate type; type IV, burst type.

RESULTS

There were 146 patients in the group 1, of which 20.55% (30/146) were type I, 33.56% (49/146) were type II, 15.75% (23/146) were type III, and 30.14% (44/146) were type IV. There were 227 patients in the group 2, of which 57.27% (130/227) were type I, 5.29% (12/227) were type II, 35.24% (80/227) were type III, and 2.20% (5/227) were type IV. There was a statistical difference in the fracture type distribution between the two groups (P < 0.05). The VAS in the group 1 was higher than that in the group 2 at the initial diagnosis (P < 0.05).

CONCLUSIONS

For patients with acute OVF, the site of pain is related to the type of fracture. The pain at the fracture site is more often observed in the central type and burst type of fractures, while pain at the non-fracture site is more often observed in the upper and lower endplate type of fractures. Additionally, when OVF are suspected, radiological assessment of thoracic and lumbar spine is recommended to better detect fractures that could cause pain distal to the site of the fracture.
