Lumbar intervertebral disc degeneration, end-plates and paraspinal muscle changes in children and adolescents with low-back pain.

The prevalence of low-back pain (LBP) in adolescents ranges from 7 to 72%. We aimed to define the radiologic characteristics of the lumbar spine in children and adolescents with LBP with/without leg pain. Two hundred and fourteen children and adolescents, who were born between 2001 and 2009 and had lumbar spine MRI for LBP with/without leg pain, were evaluated in terms of intervertebral disc degeneration (IVDD), end-plates and paraspinal muscle changes on lumbar spine MRIs. Severe IVDD was detected at all lumbar levels except for L2-L3. Modic changes were present in 4.2% of the patients. Modic changes were more common in patients with severe IVDD than in those with mild-to-moderate IVDD. Severe IVDD was significantly associated with Modic changes at the corresponding L1-L2 and L3-L4 disc levels. Girls had significantly more fatty infiltration in the paraspinal muscles when compared to boys. The risk of having severe IVDD concomitant with Modic changes was high [odds ratio (OR), 8.6]. The OR was 20.7 for predicting the presence of severe IVDD at any level if Modic changes presented particularly at the L3-L4 level. The ORs of Modic changes presented at any lumbar level at the background of fat-infiltrated multifidus at L3-L4 and L4-L5 levels were 8.3 and 9.1, respectively. Fatty infiltration in the paraspinal muscles and IVDD were closely associated with Modic changes in children and adolescents with LBP. Lumbar IVDD in children and adolescents could be the result of a mechanical pathology.

Comprehensive non-surgical treatment decreased the need for spine surgery in patients with spondylolisthesis: Three-year results.

BACKGROUND: Non-surgical treatment is the primary approach to degenerative conditions of the lumbar spine and may involve multiple modalities. There is little literature to guide an evidence-based approach to care. OBJECTIVE: To determine the effectiveness of CNT (comprehensive non-surgical treatment) in patients with degenerative spondylolisthesis (DS) and spondylolytic spondylolisthesis (SS), and to identify predictor variables for success of CNT in avoiding surgery. METHODS: All patients who underwent CNT for spondylolisthesis (n: 203) were included. CNT consisted of patient education, pain control with transforaminal epidural steroid injections (TFEs) and/or medications, and exercise programs. RESULTS: Surgical and non-surgical patients were similar in age, smoking status, comorbidity scores, facet joint widening, and translation of spondylolisthesis. After CNT, only 21.6% of patients with DS and 31.3% of patients with SS chose to have surgery in 3-years follow-up. The non-surgical group reported significantly better pain relief (73.6% vs 55%) after TFEs for a longer period (152.8 vs 45.6 days) and lower opioid use than the surgical group (28.2% vs 55.3%). CONCLUSIONS: CNT is effective in spondylolisthesis and more successful in DS than SS. CNT may decrease the need for surgery, particularly in patients who report pain relief greater than 70% for average five months after TFEs.

The effect of transforaminal epidural steroid injections in patients with spondylolisthesis.

BACKGROUND: Transforaminal epidural steroid injection (TFE) is a widely accepted non-surgical treatment for pain in patients with spondylolisthesis. However, the effectiveness of TFE has not been compared in patients with degenerative (DS) and isthmic spondylolisthesis (IS). OBJECTIVE: To compare the effectiveness of bilateral TFEs in DS and IS. METHODS: Patients who underwent bilateral TFEs for spondylolisthesis at University of California San Francisco Orthopaedic Institute from 2009 to 2014 were evaluated retrospectively. RESULTS: DS patients (120 female, 51 male) were significantly older and had higher comorbidity than those with IS (18 female, 14 male). They had better pain relief after TFE than patients with IS (72.11 ± 27.46% vs 54.39 ± 34.31%; p = 0.009). The number of TFEs, the mean duration of pain relief after TFE, follow-up periods, translation and facet joint widening were similar in DS and IS groups (p > 0.05). DS group had higher successful treatment rate (66.1% vs 46.9%, p = 0.009) and longer duration of pain relief (181.29 ± 241.37 vs 140.07 ± 183.62 days, p = 0.065) compared to IS group. CONCLUSIONS: Bilateral TFEs at the level of spondylolisthesis effectively decreased pain in patients. TFEs provided better pain relief for longer duration in patients with DS than for those with IS.
