Clinical Trial Controlled Clinical Trial
Physician referral to physical therapy in a cohort of workers compensated for low back pain.
This study described the physical therapy referral of workers compensated for back injury; characterized physical therapy by duration and choice of therapeutic techniques; and compared workers who were and were not referred for physical therapy in terms of age, gender, diagnosis, and absence from work. ⋯ This study demonstrated that physicians request physical therapy services based on certain patient characteristics. Patients who were referred earlier tended to return to work sooner than those who were referred later, which indicates that timing of physical therapy is an important factor in the rehabilitation of workers with low back pain.

In this 3-yr longitudinal study we investigated the occurrence of low-back pain and anatomic changes in the low back in relation to loading and injuries among 98 adolescents: 33 nonathletes (16 boys, 17 girls), 34 boy athletes (17 ice hockey, 17 soccer players), and 31 girl athletes (17 figure skaters, 14 gymnasts). During the 3-yr follow-up, low-back pain lasting longer than 1 wk was reported by 29 (45%; 95% CI, 32%-57%) athletes and by 6 (18%; 95% CI, 7%-35%) nonathletes (P = 0.0099). ⋯ Among 43 girls participating in baseline and follow-up MRI examinations of the lumbar spine, new MRI abnormalities were found in 6 of 8 reporting acute back injury (75%; 95% CI, 35%-97%) and in 8 of the remaining 35 girls (23%; 95% CI 10% to 40%) (P = 0.018). In conclusion, excessive loading that involves a risk for acute low-back injuries during the growth spurt is harmful to the lower back.

Eighty adult patients, 33 men and 47 women, mean age 46 years (SD 11.8, range 19-74 years), were evaluated 5 years after low-back surgery. The mean duration of symptoms before operation was 8.7 (SD 7.1) years. The purpose was to evaluate the 5-year outcome of low-back surgery, to find the best predictors for the outcome, and to find out if a correlation exists between the patient's sense of coherence and the outcome of low-back surgery. ⋯ In all patients, the Oswestry total index before the index operation is suggested to be a predictor of the final outcome. In multiple regression analysis, the number of previous operations and the preoperatively recorded Oswestry total index appeared to be the best predictors for outcome of low-back surgery. We also found that the SOC scale correlated significantly with the Oswestry total index and seems to provide a possible explanation of ability to cope with the disability and pain associated with low-back disorders.

Chronic low back pain patients chosen for lumbar fusion surgery were entered into a prospective study with the aim of evaluating whether pre-operative pharmacological pain classification correlated with the outcome of surgical treatment. Twenty consecutive patients (mean age 39 years, range 29-50 years) with a mean pain duration of 4.6 years (range 1-8 years) participated. The patients' pain, disability and work situation were evaluated pre- and post-operatively. ⋯ In the group with non-responding pain surgical outcome was significantly poorer (P < 0.01), and was ranked as excellent/good in only one out of seven patients. There was a significant improvement (P < 0.05) concerning both pain and disability in the nociceptive group, but not in the non-responding group. Pre-operative pharmacological pain testing may be useful as a predictor of surgical outcome and we suggest that it can be employed as a means to identify patients with non-responding pain and poor surgical prognosis.

Review Case Reports
Urinary bladder dysfunction following anterior lumbosacral spine fusion: case report and review of the literature.
A 34-year-old woman suffering from chronic degenerative low back pain involving L5-S1 disc space, refractory to conservative treatment, underwent spinal fusion. A combined instrumented posterolateral, followed by anterior, interbody allograft fusion through a left retroperitoneal approach was performed. Postoperatively, the patient was unable to evacuate her bladder and control her micturition. ⋯ A self-catheterisation regime was instituted with a diagnosis of parasympathetic nerve injury during the anterior spinal fusion. After a period of 3 months, the patient regained control of urination. We report this case to highlight the importance of protecting the parasympathetic presacral nerve during L5-S1 anterior interbody fusion, as injury to this nerve affects urinary evacuation.
