Spontaneous remodeling of the spinal canal after conservative management of thoracolumbar burst fractures.

Study Design: Forty-two conservatively treated patients with a burst fracture of the thoracic, thoracolumbar, or lumbar spine with more than 25% stenosis of the spinal canal were reviewed more than 1 year after injury to investigate spontaneous remodeling of the spinal canal.

Objectives: To investigate the natural development of the changes in the spinal canal after thoracolumbar burst fractures.

Summary Of The Background Data: Surgical removal of bony fragments from the spinal canal may restore the shape of the spinal canal after burst fractures.

Lay attitudes to dental appearance and need for orthodontic treatment.

In provision of advice about aesthetic treatment need, visual stimuli as a tool in communication may have some advantages compared with verbal descriptions, in particular when children are addressed. The Aesthetic Component (AC) of the Index of Orthodontic Treatment Need is an illustrated scale for rating of dental attractiveness developed in the UK and based on lay adults' ratings of dental photographs. This scale has also been recommended for use in patient education.

Peroneus longus and tibialis anterior muscle activity in the stance phase. A quantified electromyographic study of 10 controls and 25 patients with chronic ankle instability.

The electromyographic activity of the peroneus longus and anterior tibial muscles of 25 patients with chronic ankle instability (18 patients with bilateral symptoms and 7 patients with unilateral complaints) and 10 controls was registered during the stance phase under different walking conditions. With balance secured by external support, there was a variable amount of peroneal activity, most of which was found in the third quarter of stance. A high increase in peroneus longus activity starting after foot-flat was found when subjects had to maintain balance in a natural way.

Potential for recurrence of hallux valgus after a modified Hohmann osteotomy: a biomechanical analysis.

On the basis of a biomechanical model the present study investigates whether a foot-widening effect, which may result in recurrence of bunions, can be demonstrated in operated patients. Therefore, the medial deviation of the first metatarsal head as a result of flexion forces on the hallux was measured in eight patients with clinical idiopathic hallux valgus, who underwent a modified Hohmann osteotomy, and in eight "normal" persons. We found that (1) before osteotomy, all forefeet broadened while pressing the big toe downward, and (2) after surgery, widening of the forefeet on average had significantly diminished, but still existed, which might explain the development of recurrences.
