Case Report: Surgical Management of Painful Manubriosternal Pseudoarthrosis

A 31-year-old male amateur bodybuilder presented with a 2-year history of chronic pain over the sternum and a clicking sensation in the chest wall on movement. Ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) showed no cause for his symptoms. Dynamic ultrasound scan performed at a specialist sports center revealed pseudoarthrosis of the manubriosternal joint (MSJ). After a period of conservative management (rest and analgesia), he failed to improve and underwent debridement and fusion of the MSJ with plates and screws. At follow-up 23 months later, he remains pain-free and has returned to weight lifting and bodybuilding.

Comparison of relapsing polychondritis patients with and without central nervous system involvement: A retrospective study of 181 patients

The relapsing polychondritis (RP) patients with central nervous system (CNS) involvement were rare. We aimed to determine the clinical characteristics of RP patients with CNS involvement. The clinical data of 181 RP patients, hospitalized at Peking Union Medical College Hospital between December 2005 and February 2019, were collected. The patients were categorized into two subgroups: 25 RP patients with CNS involvement, and 156 RP patients without CNS involvement. The involvement of the ear was more frequent in RP patients with CNS involvement, compared with those of RP patients without CNS involvement ( P < 0.01). After controlling sex and the admission age, logistic regression analysis revealed hypertension (odds ratio = 4.308, P = 0.006) and involvement of eye (odds ratio = 5.158, P = 0.001) and heart (odds ratio = 3.216, P = 0.025) were correlated with RP patients with CNS involvement, respectively. In addition, pulmonary infection (odds ratio = 0.170, P = 0.020), tracheal involvement (odds ratio = 0.073, P < 0.01), and involvement of laryngeal (odds ratio = 0.034, P = 0.001), costochondral joint (odds ratio = 0.311, P = 0.013), sternoclavicular joint (odds ratio = 0.163, P = 0.017) and manubriosternal joint (odds ratio = 0.171, P = 0.021) were associated with RP patients without CNS involvement, respectively. In contrast to RP patients without CNS involvement, the incidence of ear involvement was higher in RP patients with CNS involvement. After controlling the potential confounding factor sex and the admission age, hypertension and involvement of eye and heart were related with RP patients with CNS involvement, respectively.

Septic arthritis of the manubriosternal joint presenting as a chest-wall swelling in an immunocompetent patient

Septic arthritis of the manubriosternal joint is a rare pathology, often mistaken for other disease processes given its location and chest pain symptoms. We present a case of a 58-year-old man presenting with a dull ache in his chest after returning from a holiday. Initially under the care of the physicians locally, he was investigated for respiratory and cardiac causes of chest pain with no findings. Eventually, a lump was noted on examination of the chest prompting further imaging, which confirmed a diagnosis of manubriosternal septic arthritis. He was discussed and referred to tertiary cardiothoracics, who recommended conservative treatment with 6 weeks of antibiotics. To date, there has been a good recovery. We present this case alongside a discussion of the limited literature, in particular highlighting how difficult a diagnosis it is to make but one that surgeons and medics alike should be aware of.
