[ 3 , 4 , 8 , 9 , 25 , 28 ] However, arthroscopic resection of dorsal ganglions has become increasingly popular. The cause of intramuscular cysts is not entirely clear but may be similar to that of paralabral cysts in the shoulder and hip and parameniscal cysts in the knee. These are also known as ganglia (or a ganglion). David Tallman, DC, NMD Articular cysts are commonly encountered in the orthopedic practice. From their common origin at a joint or tendon, ganglion cysts may form in a wide range of locations. At the shoulder, they typically occur at the acromioclavicular joint or along the biceps tendon. (5-9) There is only one other case in the literature describing an IOG cyst of the humerus, while most papers describe cystic lesions of the carpal and tarsal bones. Intraosseous ganglion (IOG) cysts of the humerus is a rare and often painful condition. Paralabral Cysts. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. J Foot Ankle Surg 33:633-5,1994. Intraosseous ganglion cysts are rare and occur most frequently in the long bones of the lower limb and carpals. Lennard Funk, 2011. A ganglion cyst is a common, benign (noncancerous), fluid-filled lump found on joints or tendons.. Rarely, intraosseous ganglion cysts occur, sometimes in combination with a cyst in the overlying soft tissue. The most accepted surgical treatment for ganglion cysts involves removal of the masses by means of an open surgical technique. They are pockets of joint fluid that develop outside of the joint under tears of the labrum. These may … The treatment options include rotator cuff repair, excisional AC joint arthroplasty and resection of the cyst base, aspiration, hemi‐arthroplasty, and reverse total shoulder arthroplasty 1. Paralabral cysts are swellings that arise around the socket of the shoulder joint (glenoid). , Histologically intraosseous ganglion cyst has to be differentiated from subchondral cyst secondary to degenerative joint disease. We present the first reported case of complete, spontaneous resolution of a massive AC joint cyst without the need for surgical intervention. Intraosseous ganglia are benign cystic and often multiloculated lesions composed of fibrous tissue with extensive mucoid changes located in the subchondral bone adjacent to a joint. They can be sequelae to chronic sprains and strains, and can be a source of juxta-articular aberrancies. Rotator cuff tears were present in 36 patients, and 79% of all tears occurred in supraspinatus tendon. Treatment is surgery including curettage and bone graft. Ganglion cysts typically occur in soft tissue near limb joints. 1, 2 We report an intraosseous ganglion cyst of the sternoclavicular joint. INTRODUCTION. Most cysts (94%) demonstrated communication with the joint post-arthrogram. Ganglion cyst. A total of 11 cases of intraosseous ganglion of the proximal humerus have been reported in the literature so far. This article will describe the most common types of non-inflammatory degenerative articular intraosseous cysts found in the author’s orthopedic practice, which are subchondral cysts and […] Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion.
