Septic arthritis of the sternoclavicular joint due to gram-positive microorganisms.

Infectious arthritis of the sternoclavicular (SC) joint is a known complication of intravenous drug abuse. Most reported cases have been caused by gram-negative microorganisms. Patients with this form of septic arthritis usually have protracted illnesses and require both medical and surgical, therapy. During 18 months we saw four cases of SC septic arthritis cause by gram-positive microorganisms. Three cases were related to heroin use and Staphylococcus aureus was the causative organisms. Streptococcus pneumoniae was isolated in the remaining patient. All patients had the abrupt onset of SC joint swelling and tenderness as the initial complaint and all responded favorably to appropriate intravenous drug therapy.

MR imaging of the sternoclavicular joint following trauma.

The purpose of this study is to describe the magnetic resonance imaging (MRI) findings of the sternoclavicular (SC) joint seen in patients who presented to our department with joint pain related to trauma. Clinical history and MRI findings on 41 patients were reviewed retrospectively to establish types and frequencies of soft tissue injuries and subluxations. Because both SC joints were imaged, the asymptomatic joints were used as a control group. Articular disk injuries were seen in 80% of patients. Injuries of the anterior, posterior, interclavicular and costoclavicular ligaments were seen in 73%, 39%, 29% and 14% of patients, respectively. Most clavicular subluxations were in the superior and posterior directions. Posterior impingement of mediastinal structures was seen in cases of posterior clavicular subluxation as well as in cases of retrosternal inflammatory or fibrotic tissue without clavicular subluxation. Biomechanical models of the SC joint are discussed to explain how different ligamentous injuries typically result in different types of subluxations.

Computed tomography manifestations of brucellosis of the sternoclavicular joint.

Computed tomography (CT) in three patients with sternoclavicular brucellosis revealed the following features: soft-tissue mass centred around the joint, sclerosis with or without lysis of the periarticular bone, and destruction and irregularity of the cortex of the sternal and clavicular articular surfaces. The CT features, in the appropriate clinical setting, should help in making the correct diagnosis and managing this serious but rare manifestation of brucellosis.
