“…1c). Previously, the articular disc of the human SCJ was classified into two types, complete and incomplete (DePalma 1959;Brossmann et al 1996;Takeshige et al 1998;Barbaix et al 2000). The complete type of disc is round in shape and therefore corresponds to the discoid type in the present study.…”

“…Furthermore, the degree of the movement of the human SCJ between the articular disc and the clavicle is still controversial. Johnson and Ellis (2005a) reported that the movement between the articular disc and the clavicle is extensive, while Barbaix et al (2000) claimed that the movement between them is limited. In accordance with Barbaix et al (2000), the present study has demonstrated that the falciform rough zone on the clavicular surface of the articular disc was directly attached to the medial region of the sternal end of the clavicle (Fig.…”

“…The sternoclavicular joint (SCJ) consists of the sternal end of the clavicle, the clavicular notch of the sternum, and the adjacent superior surface of the first costal cartilage (Brossmann et al 1996; Barbaix et al 2000;Johnson and Ellis 2005a). The SCJ is the only joint connecting the body trunk with the pectoral girdle (Johnson and Ellis 2005b), which hence enables the SCJ to participate deeply in the movement of the upper limb.…”

Macroscopic and histological observations on the human sternoclavicular joint disc

To know the detailed morphology of the human sternoclavicular joint and its articular disc is essential to understanding the movement of this joint and the functional role of the disc. In the present study, 51 articular discs of the sternoclavicular joint of 29 Japanese cadavers were macroscopically examined and then embedded in paraffin to make a complete series of coronal sections for light microscopic observation. We classified the articular discs into three types, discoid, ring, and meniscoid. The discoid-type disc was flattened and round in shape, whereas the other two types had partial defects in the centers (ring type) or in the periphery (meniscoid type). We found the bony process that protruded from the sternal end of the clavicle and fitted into the defect part of the ring- or meniscoid-type discs. The mean values of this bony process of the clavicle adjacent to the articular disc were 2.1, 4.7, and 6.0 mm, respectively, in the three types of articular disc. The movement between the articular disc and the clavicle may be limited, because the articular disc was directly attached to the clavicle on its medial region. The present histological observation demonstrated that the sternal side of the disc was composed of fibrocartilage and dense connective tissue. The clavicular side of the disc was composed of only fibrocartilage. The clavicular side of the articular disc of the sternoclavicular joint has the function of resisting the compressive load to the clavicular surface.

“…12 The disk is more closely associated with the clavicle than the sternum, and most of the motion across the SC joint occurs between the articular cartilage of the manubrium and the medial surface of the disk. 13 The primary function of the intra-articular disk has been debated in the past; however, researchers have suggested that the disk functions to decrease perceived bony incongruity between the articular surfaces 10 and to diminish the force transmission between the medial clavicle and the manubrium. 14 The costoclavicular ligament, also known as the rhomboid ligament, is a stout ligament found between the costochondral junction of the first rib and the costoclavicular tubercle on the inferior aspect of the medial clavicle.…”

Arthroscopy Techniques

Open resection arthroplasty of the sternoclavicular (SC) joint has historically provided good long-term results in patients with symptomatic osteoarthritis of the SC joint. However, the procedure is rarely performed because of the risk of injury to vital mediastinal structures and concern regarding postoperative joint instability. Arthroscopic decompression of the SC joint has therefore emerged as a potential treatment option because of many recognized advantages including minimal tissue dissection, maintenance of joint stability, avoidance of posterior SC joint dissection, expeditious recovery, and improved cosmesis. There are, however, safety concerns given the proximity of neurovascular structures. In this article we demonstrate a technique for arthroscopic SC joint resection arthroplasty in a 26-year-old active man with bilateral, painful, idiopathic degenerative SC joint osteoarthritis. This case also highlights the pearls and pitfalls of arthroscopic resection arthroplasty for the SC joint. There were no perioperative complications. Four months postoperatively, the patient had returned to full activities, including weightlifting, without pain or evidence of SC joint instability. One year postoperatively, the patient showed substantial improvements in the American Shoulder and Elbow Surgeons score; Single Assessment Numeric Evaluation score; Quick Disabilities of the Arm, Shoulder and Hand score; and Short Form 12 Physical Component Summary score over preoperative baseline values.

“…[13][14][15] Histologically, the intra-articular disk is formed from fibrocartilage and has a similar structure to the menisci in the knee and the acromioclavicular joint. 16 There is a relatively small area of bony congruence at the inferior part of the joint between the sternum and medial end of the clavicle. Whereas the angle of inclination of the medial end clavicle in the axial plane is variable, the angle of inclination of the sternum has been found to be consistently 30 to the vertical.…”

Arthroscopic Intra-articular Disk Excision of the Sternoclavicular Joint

2012

View full text Add to dashboard Cite

The sternoclavicular joint (SCJ) has a complete intra-articular disk that can be damaged either as a result of trauma or as part of ongoing degenerative joint disease. Although often asymptomatic, SCJ disk tears may lead to mechanical symptoms and pain. Previously, isolated symptomatic SCJ disk tears have only occasionally been mentioned in the literature with a few associated case reports of diskectomy by open arthrotomy. With improved imaging and availability of magnetic resonance imaging scans and the advent of SCJ arthroscopy it is now possible to treat symptomatic SCJ disk tears by arthroscopic excision. In this Technical Note, we describe the diagnosis of a torn SCJ disk and the technique of arthroscopic excision of a torn SCJ disk.
