Occipitocervical fixation and spondylodesis is indicated in various cases of occipitocervical instability. The aim of this retrospective study was to evaluate the results of occipitocervical fixation at our institutions. Between 1997 and 2007, a total of 57 patients underwent occipitocervical fixation (OC) there were 25 men and 32 women, from 4 to 77 years of age. 2 groups, group one - tying wires or cables and group two - screw-rod or screw-plate systems. Indications included trauma in 15, rheumatoid arthritis (RA) in 28, destruction due to psoriasis in one, tumour in eight, and congenital anomalies in five patients. The patients were evaluated at a final follow-up ranging between 12 and 132 months after the primary surgery (average, 42.7 months). Indications for surgery and the method and extent of instrumentation were recorded. The evaluation included pain and neurological deficit assessment, radiographic evidence of the stability of fixation and bone union and intra-operative and early and late post-operative complications.PURPOSE OF THE STUDY
MATERIAL + METHODS
The anterior approach to the thoracic and lumbar spine is used with increasing frequency for various indications. With the advent of prosthetic intervertebral disc replacement, its use has become even more frequent and has often been associated with serious complications. The aim of this study was to evaluate vascular complications in patients who underwent anterior spinal surgery of the thoracic and lumbar spine. We performed a total of 531 operations of the thoracolumbar spine from the anterior approach. In 12 cases, after exposure of the body of the first or second thoracic vertebrae, we employed the Smith-Robinson technique to expose the cervical spine. We used sternotomy in six, posterolateral thoracotomy in 209, pararectal retroperitoneal approach in 239, anterolateral lumbotomy in 58 and the transperitoneal approach in seven patients. The aim of surgery was somatectomy in 190 patients and discectomy in 341 patients. Sternotomy and transperitoneal approaches were carried out by a thoracic or vascular surgeon and all the other procedures were done by the first author. The indications for spinal surgery included an accident in 171, tumour in 56, spondylodiscitis in 43 and a degenerative disease in 261 patients.PURPOSE OF THE STUDY
MATERIAL
At our Department, we prefer surgical treatment of all patients with Type II and III fractures of the dens, regardless of the age, with the exception of non-displaced fractures or perfectly reduced fractures in young patients. We treated surgically 28 patients 65 years old and older with dens fractures. The group consisted of 13 men and 15 women with a mean age of 77.4 years (range, 65–90 years). According to the type of treatment, anterior srew fixation or posterior C1–C2 fixation, the whole cohort was divided into 2 groups that were subdivided into two age groups of patients 65–74 years old and 75 years old and older. The age group of patients 65–74 years old included 8 patients with a mean age of 68.5 years and the mean age of the age group of patients 75 and more years old was 81 years. The injury was caused in 22 cases by a fall, in 5 by a car accident. Only in 1 case the injury was caused differently. Neurological deficits were found in three patients, all of them Frankel D type. All patients with injury to the dens underwent radiograph examination in the lateral and transoral projections and CT scan including the sagittal and frontal reconstructions of the atlantoaxial complex and in most cases also MRI examination to eliminate injury to the transverse ligament of the atlas. Based on these examinations, the type of injury was determined and method of treatment indicated. Final retrospective evaluation of the patients was carried out at the interval of 12 to 78 months after the primary surgery (mean 31.3 months) taking into account aetiology of the injury, type of injury, neurological finding, method of treatment, union of the dens fracture line or, where appropriate, C1–C2 fusion, stability of the spine and the final outcome. Statistical analysis was based on X2-test.Purpose of the Study
Material and Methods
Spinal injuries in children are rare and account for a low proportion of all childhood injuries. Because of higher mobility and elasticity of the spine and a lower body mass in children, spinal injuries are not frequent and represent only 2 to 5 % of all spinal injuries. All patients from birth to the completed 18th year of age treated in our departments between 1996 and 2005 were included in this study. The patients, evaluated in three age categories (0–9, 10–14, 15–18), were allocated to two groups according to the method of treatment used (conservative or surgical). The information on patients treated conservatively was drawn from medical records; the surgically treated patients were invited for a check-up.INTRODUCTION
MATERIAL
We describe the results of 287 intra-articular fractures of the calcaneum in 247 patients treated by minimally-invasive reduction and K-wire fixation between 1994 and 2003. There were 210 men (85%) and 37 women (15%). The most common cause of injury was a fall from a height in 237 patients (96%). Fracture classification was based on the method described by Sanders and Essex-Lopresti. All patients were operated on within 21 days of injury and 89% (220) within 48 hours. The reduction was graded as nearly anatomical (less than 2 mm residual articular displacement and satisfactory overall alignment) in 212 (73.9%) fractures. There were 20 cases (7%) of superficial pin-track infection and five (1.7%) of deep infection. All healed at a mean of 6 weeks (3 to 19). Loss of reduction was observed in 13 fractures (4.5%) and a musculocutaneous flap was needed in three (1%). The results were evaluated in 176 patients (205 fractures) with a mean age of 44.3 years (13 to 67), available for follow-up at a mean of 43.4 months (25 to 87) using the Creighton-Nebraska Health Foundation Assessment score. The mean score was 83.9 points (63 to 100). There were 29 (16.5%) excellent, 98 (55.7%) good, 26 (14.8%) fair and 23 (13%) poor results. A total of 130 patients (73.9%) were able to return to their original occupation at a mean of 5.6 months (3.2 to 12.5) after the injury. Semi-open reduction and percutaneous fixation is an effective treatment for displaced intra-articular fractures of the calcaneum.
