[Precise sacroiliac joint screw insertion without computed tomography, digital volume tomography or navigation systems].

Objective: Improvement of sacroiliac positioning of screws by detailed preoperative planning with a DICOM (Digital Imaging and Communications in Medicine-the international standard to store and process medical imaging information) workstation in the absence of advanced technical facilities like intraoperative computer tomography (CT), digital volume tomography (DVT) or a navigation system.

[Acute exacerbation of chronic CLL with multiple pathological fractures : A rarity].

Chronic lymphatic leukaemia (CLL) is one of the most common leukaemic diseases in middle Europe. Pathological fractures are rare findings in patients with CLL. The diagnosis of CLL is in most cases an incidental finding as it often stays asymptomatic for years.

[Lumbopelvic stabilization for bilateral lumbosacral instabilities: indications and techniques].

Background: Bilateral lumbopelvic instabilities are rare; for the affected patients, however, they mean a severe reduction in quality of life. Optimal results can only be achieved with a well-adapted therapy algorithm that balances surgery and non-surgical procedures.

Objectives: The present article addresses the indications, strategy, and techniques of bilateral lumbopelvic fixation in the operative treatment of bilateral lumbopelvic injuries and review of the literature and personal experience.

[The pressure-sensitive swelling in the knee as a sign for a monoclonal gammopathy of undetermined specificity (MGUS)].

AL amyloidosis (AL-A) is seen in about 6-15 % of patients with multiple myeloma. In contrast, the sporadic occurrence of AL-A is a rarity. The presence of amyloid is often found in the respiratory tract followed by the lung, the eyelids, the skin and the lower urinary tract, while the presence in soft tissues or bone is rather uncommon.
