Intramedullary compression device for proximal ulna fracture.

Proximal ulna fractures account for 20% of all proximal forearm fractures. Many treatment options are available for such fractures, such as cast immobilisation, plate and screw fixation, tension band wiring and intramedullary screw fixation, depending on the fracture pattern. Due to the subcutaneous nature of the proximal forearm, it is vulnerable to open injuries over the dorsal aspect of the proximal ulna. This may in turn prove challenging, as it is critical to obtain adequate soft tissue coverage to reduce the risk of implant exposure and bony infections. We herein describe a patient with a Gustillo III-B open fracture of the proximal ulna, treated with minimally invasive intramedullary screw fixation using a 6.0-mm cannulated headless titanium compression screw (FusiFIX, Péronnas, France).

Asymptomatic cement embolism in the right atrium after vertebroplasty using high-viscosity cement: a case report.

A 52-year-old woman underwent vertebroplasty for fractures of the T10, T11, and L2 vertebrae secondary to multiple myeloma. She was discharged uneventfully within a week. Nine months later, she was readmitted for syncope. Echocardiography revealed a mass in the right atrium. Magnetic resonance imaging (MRI) revealed a low signal intensity irregular mass (8x7 mm) and a comma-shaped mass (12 mm) in the right atrium. She was prophylactically anticoagulated for the probable emboli. Repeat cardiac MRI performed 2 weeks later showed that the size of the masses remained unchanged. Surgical intervention was not suggested by the cardiothoracic surgeons. Three months later, the patient remained uneventful.

Does a positive neer impingement sign reflect rotator cuff contact with the acromion?

BACKGROUND: One possible cause of shoulder pain is rotator cuff contact with the superior glenoid (cuff-glenoid contact) with the arm in flexion, as occurs during a Neer impingement sign. It has been assumed that the pain with a Neer impingement sign on physical examination of the shoulder was secondary to the rotator cuff making contact with the anterior and lateral acromion. QUESTIONS/PURPOSES: We determined if the arm position where pain occurs with a Neer impingement sign would correlate with the position where the rotator cuff made contact with the superior glenoid, as determined by arthroscopic evaluation. PATIENTS AND METHODS: We prospectively studied 398 consecutive patients with a positive Neer impingement sign during office examination and used a handheld goniometer to measure (in degrees of flexion) the arm position in which impingement pain occurred. During subsequent arthroscopy, the arm was moved into a similar position, and we measured the arm's position in flexion at the point the rotator cuff made contact with the superior glenoid using a handheld goniometer. We compared the degrees of flexion at which pain occurred preoperatively and at which there was cuff-glenoid contact. RESULTS: Among the 398 patients, 302 (76%) had arthroscopically documented cuff-glenoid contact, whereas 96 did not. For the 302 patients with a positive Neer sign preoperatively and with arthroscopically documented cuff-glenoid contact, the average preoperative impingement pain position was 120.1°±26.7°, similar to that of the average intraoperative cuff-glenoid contact position of 120.6°±14.7°. CONCLUSIONS: Our data suggest pain associated with a positive Neer sign more often relates to contact of the rotator cuff with the superior glenoid than to contact between the rotator cuff and acromion.
