Nonspondylolytic etiologies of lumbar pain in the young athlete.

Approximately 50% of adolescent athletes with persistent lumbar pain can be diagnosed with spondylolysis or spondylolisthesis. The remaining 50% will have suffered injury of the vertebral body, intervertebral disc, ring apophysis, pelvis, articular processes, spinous processes, interspinous ligament, or other soft tissues of the lumbar spine. The adolescent spine is prone to these injuries as a consequence of the growth spurt and skeletal immaturity. Accurate diagnosis is mandatory in order to achieve successful treatment. History, physical examination, imaging modalities, and precision spinal injections can be employed to accurately diagnose the source of the symptoms. Appropriate treatment measures can then be prescribed to optimally treat the adolescent spine injury.

Incidence of vocal cord dysfunction after fluoroscopically guided steroid injections in the axial skeleton.

OBJECTIVE: To report on the incidence of dysphonia and/or associated throat symptoms after steroid injections in the axial skeleton. DESIGN: A prospective cohort study. SETTING: Academic spine center. PARTICIPANTS: Patients (N = 100) undergoing a diagnostic injection followed by a therapeutic injection in the axial skeleton. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Presence or absence of dysphonia and/or associated throat symptoms, as determined by completion of a predetermined 10-item questionnaire. This questionnaire was administered before participation in the study and at specific intervals after a diagnostic injection and, again, after a therapeutic spinal injection. RESULTS: There was a 12% incidence of transient dysphonia and/or associated throat symptoms in this study population after a therapeutic injection. CONCLUSIONS: Throat symptoms are a potential, albeit transient side effect, after an epidural space corticosteroid injection. The mechanism through which dysphonia or other throat symptoms develop is unknown but appears to be mediated by a systemic steroid effect.

A critical appraisal of the evidence for selective nerve root injection in the treatment of lumbosacral radiculopathy.

OBJECTIVE: To critically review the best available trials of the utility of transforaminal epidural steroid injections (TFESIs) or selective nerve root blocks (SNRBs) to treat lumbosacral radiculopathy. DATA SOURCES: MEDLINE (PubMed, Ovid, MDConsult), EMBASE, and the Cochrane database. Databases were searched from inception through 2003. STUDY SELECTION: A database search was conducted by using the following key words: prospective , transforaminal and foraminal epidural steroid injections , selective nerve root block and injection , and periradicular and nerve root injection . We included English-language, prospective, randomized studies of patients with lower-limb radicular symptoms treated with fluoroscopically guided nerve root or transforaminal epidural injections. DATA EXTRACTION: Data were compiled for each of the following categories: inclusion criteria, randomization protocol, total number of subjects enrolled initially and at final analysis, statistical analysis utilized, documentation of technique, outcome measures, follow-up intervals and results (positive or negative), and reported complications. These data were abstracted by 1 reviewer and reviewed by a second. Study quality was assessed with the system developed by the Agency for Health Care and Policy Research. DATA SYNTHESIS: We selected 6 articles for review. Our analysis identified a single article as the highest quality study addressing the appropriate use of TFESIs or therapeutic SNRBs. Coupled with the evidence provided by 4 other articles (1 article was excluded because its patients were not truly randomized), our review of the evidence for TFESIs found level III (moderate) evidence in support of these minimally invasive and safe procedures in treating painful radicular symptoms. However, conclusive evidence (level I) is lacking. CONCLUSIONS: The evidence for TFESIs reveals level III (moderate) evidence in support of these minimally invasive and safe procedures in treating painful lumbar radicular symptoms. Current studies support use of TFESIs as a safe and minimally invasive adjunct treatment for lumbar radicular symptoms. However, more prospective, randomized, placebo-controlled studies using sham procedures are needed to provide conclusive evidence for the efficacy of TFESIs in treating lumbar radicular symptoms.

Transforaminal cervical blood patch for the treatment of post-dural puncture headache.

A 40-yr-old woman received a series of three interlaminar epidural steroid injections for the treatment of axial neck pain secondary to degenerative disc disease. Immediately after her third injection, she experienced symptoms of a dural puncture-induced headache. This headache persisted on a daily basis for 3 mos, despite two epidural blood patches using an interlaminar approach, which was finally completely abated with a transforaminal blood patch. The headache was immediately relieved and remained alleviated through the follow-up interval of 1 yr. In this patient, a fluoroscopically guided transforaminal epidural blood patch proved to be more effective than the classic blind interlaminar approach in the treatment of post-dural puncture headache.

An instance of an atypical intraspinal cyst presenting as S1 radiculopathy: a case report and brief review of pathophysiology.

Intraspinal cysts are rare, but typically they originate from a degenerate zygapophyseal joint. These cysts have been commonly referred to as juxtafacet cysts and occur concomitantly with lumbar and occasionally lower-limb radicular pain. Documented cases have shown pseudoarthroses developing from nonhealing pars defects. Histologic analyses have found synovial tissue within these fibrocartilaginous accumulations. We present a case of S1 radiculopathy indicated by an intraspinal pseudocyst arising as a complication of a chronic spondylolytic defect. A brief review of the related pathophysiology is also included.

Therapeutic selective nerve root block in the nonsurgical treatment of traumatically induced cervical spondylotic radicular pain.

OBJECTIVE: To investigate the outcomes resulting from the use of fluoroscopically guided therapeutic selective nerve root block in the nonsurgical treatment of traumatically induced cervical spondylotic radicular pain. DESIGN: Retrospective study with independent clinical review. A total of 15 patients who met specific physical examination or electrodiagnostic criteria and failed to improve clinically after at least 4 wks of physical therapy were included. Each patient demonstrated a positive response to a fluoroscopically guided cervical selective nerve root block. Therapeutic selective nerve root blocks were administered in conjunction with physical therapy. Outcome measures included visual analog scale pain scores, employment status, medication usage, and patient satisfaction. RESULTS: Patients' symptom duration before diagnostic injection averaged 13.0 mos. An average of 3.7 therapeutic injections were administered. Follow-up data collection transpired at an average of 20.7 mos after discharge from treatment. An overall good or excellent outcome was observed in three patients (20.0%). Among those treated without surgery, a significant reduction (P = 0.0313) in pain score was observed at the time of follow-up. Six patients (40.0%) proceeded to surgery. CONCLUSIONS: These initial and preliminary findings do not support the use of therapeutic selective nerve root block in the treatment of this challenging patient population with traumatically induced spondylotic radicular pain.
