Charcot arthropathy of elbow due to syringomyelia: a case series and systematic review of literature

Syringomyelia is an important etiology of Charcot arthropathy of the elbow. We present five interesting patients, along with a systematic literature review summarizing the clinical profile and management of syringomyelia-induced Charcot arthropathy of the elbow. PUBMED, SCOPUS, EMBASE, and Science Direct databases were screened for English articles published between 1980 and 2022 using the search query: "Syringomyelia" AND "elbow" AND ("arthropathy" OR "neuropathic" OR "Charcot"). Articles without full text and/or lack of conclusive evidence of elbow arthropathy due to syringomyelia were excluded. The reference lists of the selected articles were reviewed to identify additional articles describing syringomyelia-induced Charcot arthropathy of the elbow. All five patients in the current series had elbow arthritis with variable motor weakness and dissociated sensory loss. The literature review included 31 reports (45 patients) and five patients from our center (n = 50). The median age at presentation was 45 (13-77) years. The median duration of arthropathy was 24 (0.5-180) months. Thirty-three patients had isolated elbow arthropathies. The other joints affected included the shoulder (n = 13), wrist (n = 7), metacarpophalangeal joints (n = 3), and interphalangeal joints (n = 1). Chiari malformations were present in 33 (66%) patients. Sensory deficits, motor deficits, and ulnar neuropathies were described in 36 (72%), 31 (62%), and 14 (28%) patients, respectively. Surgical decompression for syringomyelia was performed in 13 (26%) patients. The presence of dissociated sensory loss, with or without motor weakness, is key to the suspicion of syringomyelia-induced Charcot arthropathy of elbow. Chiari malformation and ulnar neuropathy are frequently associated with this condition. Key Points • Charcot arthropathy of elbow is not so uncommon as believed • Syringomyelia is an important etiology of Charcot arthropathy of elbow • Therefore, all patients with elbow arthropathy of unknown etiology must be evaluated for dissociative sensory loss • Chiari malformation and ulnar neuropathy are commonly associated with syringomyelia-induced Charcot arthropathy of elbow joint.

Syringobulbia in a Setting of Charcot Arthropathy of the Elbow Secondary to Syringomyelia: A Case Report

CASE

The authors present a case of syringobulbia in a setting of elbow arthropathy due to syringomyelia. The patient had painless elbow instability with subtle neurological findings such as ulnar neuropathy, palatal palsy, and dysphonia. As she denied surgery, she was managed with physiotherapy and orthosis. At 24 months of follow-up, she had good clinical outcome without neurological or functional worsening.

CONCLUSION

Many patients with neuropathic joints due to syringomyelia present to an orthopaedician before a neurologist. A high index of suspicion and thorough neurological examination is essential. Conservative management of such a joint provided good results in this patient.

Charcot arthropathy of the shoulder joint as a presenting feature of basilar impression with syringomyelia: A case report and literature review

RATIONALE

Charcot arthropathy, also known as Neuropathic arthropathy (NA), is an unusual chronic degenerative disease. To date, there exists a paucity of research on NA caused by syringomyelia.

PATIENTS CONCERNS

A 52-year-old non-diabetic female presented with progressive swelling, pain and limited movement in her left shoulder joint combined with asthenia of her left upper extremity for three months.

DIAGNOSES

Neuropathic arthropathy of the shoulder associated with the cervicothoracic syrinx and basilar impressions was diagnosed.

INTERVENTIONS

The treatment is directed to its potential cause to cease its progression. A posterior fossa decompression (PFD) was conducted for this patient.

OUTCOMES

Postoperatively, the patient's symptoms were relieved and the size of syrinx was reduced at the 6-month follow-up.

LESSONS

Taken together with 34 previous reports identified from a PubMed search, an analysis of 35 cases of Charcot arthropathy was conducted. Surgical decompression is an effective treatment, but the optimal treatment remains controversial. Thus, the aim of this literature review was to remind us to diagnose the potential cause as early as possible and we should spare no efforts on the exploration of etiology and adjuvant therapy for this disease.
