Comparative Study
Modified plate-only open-door laminoplasty versus laminectomy and fusion for the treatment of cervical stenotic myelopathy.
The purpose of this study was to compare modified plate-only laminoplasty and laminectomy and fusion to confirm which of the 2 surgical modalities could achieve a better decompression outcome and whether a significant difference was found in postoperative complications. Clinical data were retrospectively reviewed for 141 patients with cervical stenotic myelopathy who underwent plate-only laminoplasty and laminectomy and fusion between November 2007 and June 2010. The extent of decompression was assessed by measuring the cross-sectional area of the dural sac and the distance of spinal cord drift at the 3 most narrowed levels on T2-weighted magnetic resonance imaging. ⋯ Patients who underwent plate-only laminoplasty showed a better improvement in Neck Dysfunction Index and visual analog scale scores. In addition, limited decompression, rigid reconstruction of the spinal canal, and preservation of cervical mobility combined with preservation of the posterior structure resulted in a lower rate of postoperative C5 palsy and axial pain in the modified laminoplasty group. For this reason, modified laminoplasty may be a more viable option for patients with cervical stenotic myelopathy.

Hip arthroscopy is being used with increasing frequency as the understanding of arthroscopic management of groin pain improves. To access the hip joint arthroscopically, traction must be placed on the leg. In most cases, countertraction is provided with a padded post in the groin. ⋯ No significant complications related to traction occurred during follow-up. The described technique has been used in more than 2000 hip arthroscopies without a documented groin or perineal complication. It allows easy positioning and access to the central compartment.

Subscapularis tendon tears are a well-established cause of shoulder pain. The objective of the current study was to evaluate the associated shoulder pathology in patients with full-thickness subscapularis tendon tears using magnetic resonance imaging. Forty-seven magnetic resonance imaging studies taken between 2008 and 2009 with a diagnosis of full-thickness subscapularis tendon tears were reviewed. ⋯ Average coracaohumeral distance was 14.8 vs 8.1 mm in patients with a Goutallier grade of 0 vs 3 or 4, resepectively, and 13.6 vs 8.5 mm in patients with no rotator cuff tear vs those with a supra- and infraspinatus tear, respectively. Increased age, dislocated biceps tendons, and concomitant rotator cuff tears in patients with full-thickness subscapularis tendon tears are associated with larger subscapularis tendon tear size, higher Goutallier grades, and increased subscapularis muscle volume loss. Decreased coracohumeral distance is associated with a higher Goutallier grade and rotator cuff tears.
