[Ultrasonic diagnosis of the locomotor system. A review].

The purpose of this overview is to discuss the numerous potential applications of diagnostic ultrasound in the evaluation of diseases affecting the musculoskeletal system. Traumatic and inflammatory conditions of tendons, intraarticular effusions and synovial thickening, derangement of articular cartilage, meniscal tears, rotator-cuff lesions and hip anomalies in neonates can be detected by sonography. In addition, hematomas, abscesses, cysts, soft tissue neoplasms and foreign bodies are readily identified using this technique. Sonography is noninvasive, readily accepted by the patients, relatively inexpensive and widely available. In future, further expansion of its role in the diagnostic work-up of musculoskeletal disorders is to be anticipated.

Bone Diseases

Complete sternal cleft.

Complete sternal clefts are rare congenital anomalies, which may be associated with other abnormalities of midline fusion. We here present a case with a complete cleft as the only anomaly of midline fusion.

Adult

Ultrasound guided puncture of pleural fluid collections and superficial thoracic masses.

Fluoroscopically guided percutaneous aspiration biopsy of pulmonary masses and conventional needle thoracocentesis for the diagnostic evaluation and treatment of pleural fluid collections, are well established procedures. In the abdomen, ultrasonographic guidance is a widely accepted method, but is usually considered to be of limited values in the chest because of overlying ribs and aerated lung tissue. Nevertheless, ultrasound is well suited as a guiding modality for both aspiration of pleural fluid collections and biopsy of pleural thoracic masses. We describe and discuss the method on the basis of 55 punctures in 46 patients, in most of whom previous attempts guided by radiography and clinical examination had failed. Diagnostic/therapeutic results were obtained in all cases but one. The only complication was minor pneumothorax in two patients.

Empyema

Patellectomy--a 20-year follow-up.

Twenty-seven patients with 28 patellectomies were re-examined after an average of 20 years. Twelve knees rated as excellent, ten as good and six as fair. Even though 12 patients had strenuous work, only three patients had changed occupation. Quadriceps power was on average two-thirds that of the opposite limb. Radiographs showed incipient femoro-tibial arthrosis in four patients only.

Ultrasonography of osteochondritis dissecans of the knee. A preliminary report.

Twenty-five radiographically proven cases of osteochondritis dissecans of the femoral condyles were examined by real-time sonography using a 5 MHz linear transducer. The medial condyle was involved in 19 cases and the lateral in 6. The size of the lesions varied from a few mm to more than 30 mm in diameter. The fragmentation of the subchondral bone was demonstrated in all cases, and furthermore the osteochondral fragment and the condition of the overlying articular cartilage could be assessed. The exact indications for the technique have not yet been defined, but awaits further clinical studies.
