Case Reports
The diagnosis and management of a vertebral artery loop causing cervical radiculopathy.
Cervical radiculopathies are rarely caused by vertebral artery loop formation, which is estimated to be present in less than 3% of patients. It is uncertain what causes the loop formation: some propose an association with spondylotic changes or trauma, whilst others suggest hypertension and atherosclerosis may be responsible. CASE REPORT 1: A 35-year-old male patient presented with signs and symptoms of cervical radiculopathy that was not improved with anterior cervical discectomy and fusion surgery performed 2 years beforehand. Vertebral artery loop was discovered at the level C5/6 on the MRI. Vertebral artery transposition surgery via a lateral approach was performed at the level of the left C5/6 for symptoms of left C6 radiculopathy. Deroofing of the transverse process was performed with post-surgical complete improvement in weakness and pain. CASE REPORT 2: A 48-year-old female patient presented with a 10-year history of left shoulder pain with occasional radiation into her middle three fingers accompanied by intermittent paraesthesia and weakness. Numerous shoulder surgeries, Botox injections and suprascapular nerve blocks had not provided any significant benefit. A vertebral artery loop was identified at the level of C3/4 and C4/5 on the left with cervical MRI. Transposition surgery of these two levels provided some post-surgical improvement in pain. ⋯ Vertebral artery loop formations are a rare but potential cause for cervical radiculopathy. In two cases, the loop formations were not radiographically reported on MRI, thus clinicians should be aware of this as a differential diagnosis in the management of cervical radiculopathy. The presented surgical approach may be useful in managing future cases of vertebral artery loop formation causing cervical radiculopathy resistant to conservative measures.

To assess test-retest reliability, internal consistency, construct validity, and the presence of ceiling and floor effects in the Brazilian version of the Short-Form Neck Disability Index (SF-NDI) in patients with chronic neck pain. ⋯ SF-NDI with 5 items has adequate measurement properties in Brazilian chronic neck pain patients.

This study systematically analyzed and assessed the interrelationships among vertebral anomaly location, congenital scoliosis (CS) type and associated abnormality prevalence. ⋯ Cervical malformations had higher prevalence of mixed defects, musculoskeletal and intraspinal defects and multi-region involved. Thoracic malformations had higher prevalence of intraspinal and musculoskeletal defects and more involvement of only one vertebral region. Lumbar vertebral malformation patients had much lower prevalence of intraspinal and musculoskeletal defects and more involvement of only one vertebral region. Cervical malformation was a risk factor for more associated anomalies and more severe vertebral anomalies, which deserves more attention from surgeons in outpatient clinic.

This study evaluates the influence of patient frailty status on postoperative complications in those receiving single-level lumbar fusion surgery. ⋯ Patient frailty status may serve as an important predictor of postoperative outcomes in patients receiving single-level lumbar fusion surgery.

In conservative early onset scoliosis treatment, interest in bracing is growing because repeated general anaesthesia (required by casting) has been questioned for possible brain damages. We aimed to check the results in the medium term of bracing, comparing idiopathic (IIS) to secondary (SIS) infantile scoliosis. ⋯ Bracing shows promising results in the medium term for high-degree IIS, with very few hold-ups (19%) and failures (12%). Conversely, failures prevail for SIS (full 11%), even if the partial failure (39%) is still a time-buying strategy.
