Circumferential lumbar fusion restored lordosis, provided a higher union rate with significantly fewer repeat operations, showed a tendency toward better functional outcome, and resulted in less peak back pain and leg pain than instrumented posterolateral fusion. The clinical perspective of the current study implies a recommendation to favor circumferential fusion as a definitive surgical procedure in complex lumbar pathology involving major instability, flatback, and previous disc surgery in younger patients, as compared with posterolateral fusion with pedicle screws alone.
Background and purpose Spondylodiscitis may be a serious disease due to diagnostic delay and inadequate treatment. There is no consensus on when and how to operate. We therefore retrospectively analyzed the outcome of a large series of patients treated either nonoperatively or surgically.Patients and methods Between 1992 and 2000, 163 patients (101 males) were hospitalized due to spondylodiscitis. The mean age was 56 (1-83) years. The infection was located in the cervical spine in 13 patients (8%), in the thoracic spine in 62 patients (38%), at the thoracolumbar junction in 10 patients (6%), and in the lumbo-sacral spine in 78 patients (48%). In 67 patients (41%), no microorganisms were detected. Most of the other patients had Staphylococcus aureus infection (53 patients) and/or Mycobacterium tuberculosis (22 patients). The patients were divided into 3 groups: (A) 70 patients who had nonoperative treatment, (B) 56 patients who underwent posterior decompression alone, and (C) 37 patients who underwent decompression and stabilization.Results At 12-month follow-up, nonoperative treatment (A) had failed in 8/70 patients, who had subsequently been operated. 24/56 and 6/37 had been reoperated in groups B and C, respectively. Group A patients had no neurological symptoms. In group B, 11 had neurological deficits and surgery was beneficial for 5 of them; 4 remained unchanged and 2 deteriorated (1 due to cerebral abscess). 11 patients in group C had altered neurogical deficits, which improved in 9 of them. 20 patients had died during the 1-year follow-up, 3 in hospital, directly related with infection.
Smoking was shown to have a negative effect on fusion and overall patient satisfaction, but no measurable influence on the functional outcome as assessed by the Dallas Pain Questionnaire.
Purpose and methods We reviewed the management, failure modes, and outcomes of 196 patients treated for infectious spondylodiscitis between January 1, 2000 and December 31, 2010, at the Spinal Unit, Aarhus University Hospital, Aarhus, Denmark. Patients with infectious spondylodiscitis at the site of previous spinal instrumentation, spinal metastases, and tuberculous and fungal spondylodiscitis were excluded. Results Mean age at the time of treatment was 59 (range 1-89) years. The most frequently isolated microorganism was Staphylococcus aureus. The lumbosacral spine was affected in 64 % of patients and the thoracic in 21 %. In 24 % of patients, there were neurologic compromise, four had the cauda equina syndrome and ten patients were paraplegic. Ninety-one patients were managed conservatively. Treatment failed in 12 cases, 7 patients required re-admission, 3 in-hospital deaths occurred, and 5 patients died during follow-up. Posterior debridement with pedicle screw instrumentation was performed in 75, without instrumentation in 19 cases. Seven patients underwent anterior debridement alone, and in 16 cases, anterior debridement was combined with pedicle screw instrumentation, one of which was a two-stage procedure. Re-operation took place in 12 patients during the same hospitalization and in a further 12 during follow-up. Two in-hospital deaths occurred, and five patients died during follow-up. Patients were followed for 1 year after treatment. Eight (9 %) patients treated conservatively had a mild degree of back pain, and one (1 %) patient presented with mild muscular weakness. Among surgically treated patients, 12 (10 %) had only mild neurological impairment, one foot drop, one cauda equine dysfunction, but 4 were paraplegic. Twenty-seven (23 %) complained of varying degrees of back pain. Conclusions Conservative measures are safe and effective for carefully selected patients without spondylodiscitic complications. Failure of conservative therapy requires surgery that can guarantee thorough debridement, decompression, restoration of spinal alignment, and correction of instability. Surgeons should master various techniques to achieve adequate debridement, and pedicle screw instrumentation may safely be used if needed.
Circumferential lumbar fusion demands more extensive operative resources compared with posterolateral lumbar fusion. However, 5 to 9 years after surgery, the circumferentially fused patients had a significantly improved outcome compared with those treated by means of posterolateral fusion. These new results not only emphasize the superiority of circumferential fusion in the complex pathology of the lumbar spine but are also strongly supported in all of the validated questionnaires used in the study.
During a 1-year period 100 badminton players were registered and treated in the casualty ward of Randers City Hospital, Denmark. The injuries to the badminton players constituted 5% of all sports injuries registered during the same period in the casualty wardl'2. At follow-up questionnaires were sent to all participants. Replies were received from 89 patients. Over the same period all sports participants in the hospital catchment area (30 254) were registered according to their sport affiliation (2620 badminton players -1650 men and 970 women). Of those injured 58% were men (mean age 31 years) and 42% were women (mean age 25 years). Of the injuries 55% occurred in club players, the remainder occurring during company and school sports activities. The active players were classified into three groups according to age: Group 1 under 18 years (31%); Group 218-25 years (16%); Group 3 more than 25 years (53%). According to the Abbreviated Injury Scale (AIS) 17% of the injuries were classified as minor, 56% as moderate, and 27% as severe, respectively. Of the severe injuries (AIS = 3) 56% were found in the oldest age group. AIS correlated with time absent from sport (P <0.001). Nine players (9%) reported that earlier injuries had influenced the actual accident. Most players (96%) trained one to three times a week. Sprains were the injury most commonly diagnosed (56%), fractures accounted for 5%, tom ankle ligaments were found in 10%, and 13% had ruptures to the Achilles tendon. Overall, 21% were admitted to hospital. None of the patients treated as inpatients was kept in hospital for more than 7 days. The injury caused 56% of players to be absent from work of whom 23% were absent for more than 3 weeks. After the injury 12% of the players gave up their sport, and only 4% restarted their training/sport within 1 week. As many as 28% had to avoid training and playing in matches for 8 weeks or more.Keywords: Badminton injuries, prospective study, epidemiology, traumatology, Abbreviated Injury Scale, socioeconomic consequences Participation in all kinds of sports activities has increased considerably during the past decade. In Denmark there is a long tradition of badminton. More than 170 000 players are organized into 650 clubs.Badmintoon is an indiviidual, non-contact sport requiring jumps, lunges, quick changes of direction and rapid arm movements. Most severe injuries are related to the lower limbs3. The aim of the present study was to describe the frequency, severity and pattern of badminton injuries in a population based study and to estimate the sports and socioeconomic consequences to the players. Materials and methodsThe study consisted of 100 badminton injuries registered during 1 year in the casualty ward, Department of Orthopedic Surgery, Randers city hospital, Denmark -the only hospital in a well defined geographical area representative of the country as a whole. Of the total sports injuries' 1, 5% were due to badminton. During the same period the total number of injuries registered was 17700 among a population of...
C1LMS of 95.5% and C2PS of 92.8% were confirmed to be in good position. None of the screws including the malpositioned caused VA injury, clinically or radiographically. The technique for C1LMS and C2PS fixation appears to be safe and effective.
