Functional outcome of burst fractures of the thoracolumbar spine managed non-operatively, with early ambulation, evaluated using the load sharing classification.

The purpose of this prospective study was to assess the functional outcome of conservative treatment with early ambulation of thoracolumbar burst fractures, using the Load Sharing classification. From 1997 to 2001, 60 consecutive patients with single-level thoracolumbar spinal injury, with no neurological impairment, were classified according to the Load Sharing scoring and were managed non-operatively. A custom-made thoracolumbosacral orthosis was worn by all patients for six months, and early ambulation was recommended. Several radiological parameters were evaluated; the Denis Pain and Work Scale was used to assess the clinical outcome. The average follow-up period was 42 months (range, 24 to 55 months). During this period the spinal canal occupation was significantly reduced. Other radiological parameters, such as Cobb's angle and anterior vertebral body compression, showed loss of fracture reduction, which was not statistically significant. However, the functional outcome was satisfactory in 55 of 60 patients with no complications recorded on completion of treatment. Load Sharing scoring is a reliable and easy-to-use classification for the conservative treatment and prognosis of thoracolumbar spinal fractures. Because of the three characteristics of the fracture site this classification can also predict the structural results of spinal injury, such as posttraumatic kyphosis, as well as the functional outcome in conservatively treated patients.

Neonatal screening for developmental dysplasia of the hip on the maternity wards in Crete, Greece. correlation to risk factors.

OBJECTIVE: To evaluate the effects of ultrasound examination of newborns in early detection and management of developmental dysplasia of the hip (DDH), and its correlation to known risk factors. The incidence of DDH in newborns throughout the general population of Crete has also been investigated. METHODS: From 1996 to 2000, 6,140 full-term newborns were examined in the Maternity Department of the University Hospital. All received standard assessments, with their medical history recorded, and a physical examination performed on the first and the fifth postpartum days. Ultrasonography of both hips using the Graf technique was performed on the 15th day after birth on both high-risk newborns and those with any clinical suspicion of DDH. Treatment was initiated according to the Graf classification. RESULTS: Ultrasound examination was performed on 220 newborns (3.58%). Ultrasound findings were positive in 65 neonates (10.83 per 1,000). Twenty-one neonates whose clinical examination was normal, but who underwent ultrasound because of the presence of risk factors had pathological findings on the hip sonography (32.30%) CONCLUSION: The incidence of DDH in Crete is estimated to be 10.83 per 1,000; higher than in the rest of Greece. Medical and family histories and clinical examination play an important role in the diagnosis of hip instability. Selective ultrasonography for all infants with risk factors, and those with clinical abnormality of the hip, is an adjunctive tool which aids early diagnosis and offers higher control in the results of treatment.

Posterior compact Cotrel-Dubousset instrumentation for occipitocervical, cervical and cervicothoracic fusion.

The authors report on 32 consecutive patients with instability at the craniocervical, cervical and cervicothoracic regions suffering from various pathologies, who were treated with posterior instrumentation and fusion using the posterior hooks-rods-plate cervical compact Cotrel-Dubousset (CCD) instrumentation alone or, in three patients, in combination with anterior operation. The patients were observed postoperatively for an average of 31 months (range 25-44 months) and evaluated both clinically and radiographically using the following parameters: spine anatomy and reconstruction, sagittal profile, neurologic status, functional level, complications and status of arthrodesis. All patients but one (who died) achieved a solid arthrodesis based on plain and flexion/extension roentgenograms. Cervical lordosis (skull-C7) and cervicothoracic kyphosis (C7-T2) was improved by instrumentation towards a physiological lateral curve by an average of 33% (P<0.05) and 28% (P<0.05) respectively. Anterior vertebral olisthesis was reduced in the craniocervical and cervicothoracic region, by 73% and 90% respectively. At final follow-up there was an improvement of the neurologic Frankel status by an average of 1.2 grades and of myelopathy in 75% of the operated patients. Good to excellent functional results were seen in 77% of the operated patients, while acute and chronic pain was reduced by an average of 2.4 grades, on a scale of 0-3, in operated patients. No neurovascular or pulmonary complications arose from surgery. There was no significant change in lateral spine profile and olisthesis at the latest follow-up evaluation. There were no instrument-related failures. One patient requested hardware removal in the hope of reducing postoperative pain in the cervicothoracic region. The poor and fair results were related to the lack of improvement of neurologic impairment and myelopathy. The results of this study demonstrate that cervical CCD instrumentation applied in the region of the skull to the upper thoracic region for various disorders is a simple and safe instrumentation that restores lateral spine alignment, improves the potential for a solid fusion and offers sufficient functional results in the vast majority of the operated patients. However, the use of hooks in spinal stenosis is contraindicated.

Simultaneous double interphalangeal dislocation in a finger.

A rare case of simultaneous dorsal dislocation of both interphalangeal joints in a finger is presented. Review of reported cases revealed that this injury usually occurs on the ulnar side of the hand of young male athletes and has a good outcome with conservative treatment.
