Rotator cuff tear patterns: MRI appearance and its surgical relevance.

A new perspective on rotator cuff anatomy has allowed a better understanding of the patterns of the different rotator cuff tears. It is essential for radiologists to be aware of these different patterns of tears and to understand how they might influence treatment and surgical approach. Our objective is to review the arthroscopy correlated magnetic resonance imaging appearance of the different types of rotator cuff tears based on current anatomical concepts.

Presurgical perspective and postsurgical evaluation of acromioclavicular joint instability.

Acromioclavicular joint (ACJ) dislocations are a common cause of pain in patients of any age. Athletes who participate in contact sports, such as hockey, football, rugby, and soccer, are particularly susceptible to such injuries. The ACJ has an important role in the function of the upper limb, and its complexity of movement makes it susceptible to acute injuries and chronic dysfunction with debilitating effects that must be treated appropriately and promptly to preserve function.

A pure extradural hemangioblastoma mimicking a dumbbell nerve sheath tumor in cervical spine: illustrative case.

Background: Spinal extradural hemangioblastomas (HBs) are quite uncommon, with most reported cases involving the thoracic and lumbar areas. Therefore, the presence of a dumbbell-shaped pure extradural cervical HB is exceptional, making preoperative diagnosis particularly challenging.

Observations: The authors report a case of a 27-year-old woman who presented to their outpatient clinic with progressive cervicobrachialgia and numbness in the left arm.

Can collagenase effectiveness in Dupuytren's contracture be improved by using ultrasound-guided Injection? A comparative study.

The objective of this study was to compare the effectiveness of ultrasound-guided injection of collagenase Clostridium histolyticum (CCH) in patients with Dupuytren's contracture (DC), with the standard injection. We hypothesised that the ultrasound-guided Injection of CCH is more effective than the standard injection. A prospective cohorts study in patients with DC was done.
