RESUMEN
The current concept procedures in the acute acromioclavicular joint dislocation should be divided into 2 types of structure restoration: those that provide coracoclavicular stabilization, which affects the primary healing of the coracoclavicular ligaments by vertically stabilizing the clavicle and coracoid in their anatomical positions, and those that attempt to repair the superior acromioclavicular ligament complex, which controls both horizontal and rotational stabilization. The acute acromioclavicular joint dislocation clinical outcome will be achieved if you perform both procedures. It's difficult to stabilize the acromioclavicular joint in both vertical and horizontal planes, and most current techniques aren't always effective. In this Technical Note, we discuss an arthroscopic-assisted technique that reconstructs the coracoclavicular and acromioclavicular ligaments under image intensifier guidance to achieve bidirectional (vertical and horizontal) and rotational stability.
RESUMEN
Background: Intradural herniation (IDH) or transdural disc herniation is a rare presentation of lumbar disc disease. Preoperative imaging findings should be carefully and thoroughly interpreted. Although imaging modalities such as computed tomography (CT) or magnetic resonance imaging (MRI) are readily available, a definitive diagnosis cannot be made based solely on these modalities. Operative procedures must be planned to prevent unexpected complications. Case description: A 67-year-old man presented with right lower extremity weakness and numbness with bowel and bladder involvement for 2 weeks, after falling from a standing position. MRI revealed a large herniated disc at L2-L3, which was suspected to be IDH. Posterior discectomy and interbody fusion were also performed. Intraoperative findings revealed no disc material in the epidural space or dural sac tenting. Dorsal midline durotomy was performed, and a mass-like lesion was found and resected. Subsequently, pathological analysis revealed disc tissue with evidence of moderate chronic inflammation and a focal increase in fibrosis. The patient was discharged without complications. Results Outcome: Lower extremity strength improved to grades IV-V, accompanied by a return to normal bowel and bladder function within 1 month, without any wound complications. Lower extremity strength recovered fully to grade V, and the patient started walking independently within 6 months. Conclusions: A large disc herniation, suspected to be an IDH, should be thoroughly investigated by carefully reviewing MRI scans before proceeding with any surgical procedure to prevent unexpected situations. Nonetheless, preoperative imaging alone does not ensure a definitive diagnosis, and the differential diagnosis must include other mass-like lesions. Intraoperative findings and pathological reports are essential for definitive diagnosis of IDH.
RESUMEN
The purpose of this study was to compare clinical outcomes after preganglionic versus ganglionic epidural steroid injection (ESI) using a systematic review and network meta-analysis. A systematic review and meta-regression was performed to compare postoperative outcomes between the two difference injection techniques. Relevant randomized controlled trials were identified from Medline and Scopus up to September 24, 2016. Sixteen out of 598 studies were eligible; 3, 2, and 3 studies were included in the pooling of outcomes including effectiveness, visual analog score (VAS), and complications (nerve root, injury, dural puncture, and intraneural injection). Preganglionic ESI has a 2.38 (95% CI 1.12, 5.04) times statistically significantly higher chance of effectiveness when compared to ganglionic ESI. There were differences in pain VAS and complications in lumbar radiculopathy, but these displayed no statistical significance. This meta-analysis indicated that preganglionic ESI has a statistically significantly higher chance of effectiveness when compared to ganglionic ESI. In terms of pain score and complications, there were no statistically significant differences between the two groups. These results were generally homogeneous and with little publication bias, thus should be generalizable.
