The posterior lumbar interbody fusion (PLIF) originally described in the 1940s has had varying degrees of acceptance. With the advent of newer PLIF constructs and the use of posterolateral fixation in combination with PLIF a renewed interest in PLIF has developed. The current indications for PLIF include spondylolysis, spondylolisthesis, transitional syndrome, recurrent disc disease, postlaminectomy instability, and traumatic/postinfectious instability. These indications are shared with other interbody fusion techniques, including transforaminal posterior lumbar interbody fusion, anterior lumbar interbody fusion, and posterior lateral fusion. Therefore, the selection of which radiographic and diagnostic studies as well as which constructs to utilize has become increasingly more complicated. This article identifies the most accepted indications for PLIF and a discussion of the accepted evaluations to be performed before PLIF is made. Finally, a brief description of one possible PLIF construct is presented

Far lateral disc herniation is defined as a herniated disc located at or lateral to the pedicle. The incidence of these lesions has been reported to range between 2.6 and 11.7% of all lumbar disc herniations. 1 Far lateral disc herniations result in compression of the exiting nerve root rather than the traversing nerve root (i.e., a far lateral L3-4 disc herniation results in compression of the L3 nerve root) and there is a higher incidence of involvement of the upper lumbar segments. In a review of several series, L1-2 was the affected level in 0.3%, L2-3 in 5.4%, L3-4 in 25%, L4-5 in 52%, and L5-S1 in 17% of patients (Table 1). 1 In contradistinction, medially herniated disc fragments above the L4-5 level have an incidence of only 2.5%. 1 In one series of 170 patients with far lateral disc herniations, the average age of presentation was 55, and there were 112 men and 58 women in the study. 2

A variety of modalities are available for the treatment of lumbar spinal stenosis. The nonoperative treatment techniques include anti-inflammatories, physical therapy and steroid injections. Controlled, randomized trials of these various treatment modalities have not been undertaken. The available data suggest that nonoperative treatment modalities have a sustained benefit in a minority of patients. The majority of patients who present with symptoms and signs of stenosis do not improve with nonoperative treatment, but typically do not progress over the short term. The indication to operate is based upon the severity of symptoms and the degree of associated disability. Decompressive operative techniques available for stenosis include a laminectomy, laminectomy and mesial facetectomy and laminotomies. The techniques vary in their degree of technical difficulty and the likelihood of incurring complications. The principle of decompressive surgery is to effect adequate decompression of the neural elements without inducing instability. Indications to proceed with segmental fusion are not clear. Overall, results of incorporating a fusion along with a decompression are better than with a decompression alone in selected patients, although there is an associated increase in complication potential.

Attitudes regarding surgical reconstruction of the brachial plexus have advanced with the evolution of microsurgical techniques not only in adults but also in infants with obstetrical plexus palsy. Recommendations regarding intervention range from the very conservative and nihilistic to the aggressive and unrealistic. Unfortunately, variations in the methodology and outcomes in reported clinical series have made results difficult to interpret. This article reviews the current attitudes regarding both the conservative and aggressive approaches to the management of obstetrical brachial plexus palsy and offers an algorithm for the appropriate management of these injured infants.
