Clay-shoveler's fractures are isolated, avulsion-type spinous process fractures of the lower cervical and upper thoracic vertebrae. Multi-level fractures of the spinous processes are extremely rare. We report the case of a 60-year-old female patient with a six-level isolated spinous process fracture of the thoracic spine. Our case is the fourth reported case in literature, of an isolated spinous process fracture involving five or more levels in the thoracic vertebrae.

| » Introduction|| |
Clay-shoveler's fractures are isolated, avulsion-type, spinous process fractures of the lower cervical and upper thoracic vertebrae, originally described in clay shovelers from Australia.  Hyperflexion and rotation of the spine as well as direct and/or indirect trauma may cause these fractures. X-rays and computed tomographic scans are the gold standards of investigation for the diagnosis of clay shoveler's fractures. The major complaint of patients having an isolated spinous process fracture is local pain that is usually resolved with a conservative approach. ,,, Multi-level spinous process fractures are extremely rare in literature. ,,,,,, We report a six-level isolated spinous process fracture of the thoracic spine. To the best of our knowledge, this is the fourth case of isolated spinous process fracture involving five or more thoracic vertebral levels.
| » Case Report|| |
A 60-year-old female patient was admitted to our hospital with a complaint of pain in the thoracic region that developed after an automobile accident. Her physical examination revealed tenderness in the thoracic spine. She had no neurological deficits. Radiographs of the thoracic spine and computed tomographic scans demonstrated isolated spinous process fractures of T4-T9 vertebrae without evidence of additional vertebral body lesions [Figure 1]a-c. The patient was treated conservatively with analgesics and oral muscle relaxant medication. Immobilization was maintained by a thoracolumbar hyperextension (Jewett type) brace for 6 weeks. Relief in pain was achieved gradually. The 3-month follow-up of the patient showed a good clinical outcome without neurological deficits. The computed tomographic scan revealed partial fusion of the spinous process fractures at a follow-up of 3 months [Figure 2].

| » Discussion|| |
Clay-shoveler's fractures are stable, isolated spinous process fractures of the lower cervical and upper thoracic vertebrae classically seen at the C6 or C7 level. ,,,,,,, They occur secondary to stress forces exerted by muscles and ligaments that are transmitted through the supraspinous ligaments. ,,,, Isolated spinous process fractures are mostly described at one level. Multi-level isolated spinous process fractures are extremely rare. A review of literature is given in [Table 1]. Our case is the fourth case reported in literature, of an isolated spinous process fracture involving five or more levels in the thoracic vertebrae.
The clinical presentation consists mainly of tenderness and pain in the lower cervical and upper thoracic spine. This is usually without any neurological deficit. ,,,,, If the fracture extends into the vertebral body, pedicle or lamina, concomitant spinal cord compression or instability may be detected. The fracture may characteristically be indicative of thorax, kidney or liver trauma ıf the mode of injury is severe such as sustained in an automobile or a climbing accident. Patients with multi-level thoracic clay-shoveler's fractures must be evaluated with a high index of suspicion for a coexisting pneumothorax or hemothorax. The treatment of isolated spinous process fractures is conservative aided by analgesics and spinal immobilizing braces. ,,,,,,,, Thoracolumbar braces that maintain hyperextension of the spine are recommended for multi-level clay-shoveler's fractures of the thoracic spine. Only a longstanding persistence of pain may be a relative indication for surgery carried out for isolated clay-shoveler's fractures. If the fracture extends into the vertebral body, pedicle or laminar regions, spinal instability, or nerve root or spinal cord compression must be looked for. The total duration of treatment of these patients with analgesics, muscle relaxant medication and a thoracolumbar brace is approximately for 6 weeks. In the available literature, the majority of patients treated conservatively show a good clinical outcome, as was seen in our patient.
