“…Within the canal, the ulnar nerve lies medially and the ulnar artery and vein laterally. Reports describe space occupying lesions such as ganglion cyst, 16 lipoma, 17 FCU calcific 3 of 4 birpublications.org/bjrcr tendonitis 18 and accessory abductor digiti minimi 19 causing ulna nerve symptoms, and our case suggests that hypothetically an accessory FCU insertion towards the distal radial aspect of pisiform could potentially cause reduction in canal volume and subsequent nerve compression.…”

Accessory flexor carpi ulnaris: case report and review of the literature

Most of the accessory muscles of the forearm described in the radiology literature are located either in the radial aspect of the forearm or towards the hypothenar eminence. We present an unusual case of an ulnar-sided distal forearm accessory flexor carpi ulnaris muscle presenting as a “pseudotumour“ demonstrated with both ultrasound and MRI, rarely reported in the current surgical and anatomical literature. Given the location and relation to the ulnar nerve towards Guyon’s canal, the accessory muscle may also predispose to distal ulnar nerve entrapment.

“…Typically, acute episodes of pain are single occurrences that resolve spontaneously, although patients can experience recurrence of pain months after the initial episode [22]. Occasionally, patients will present with symptoms of neuropathy [5, 6, 23]. These acute episodes of pain are what frequently lead to patients presenting for treatment and can be a diagnostic challenge for clinicians.…”

Calcium apatite deposition disease (CADD) is a common entity characterized by deposition of calcium apatite crystals within and around connective tissues, usually in a periarticular location. CADD most frequently involves the rotator cuff. However, it can theoretically occur in almost any location in the musculoskeletal system, and many different locations of CADD have been described. When CADD presents in an unexpected location it can pose a diagnostic challenge, particularly when associated with pain or swelling, and can be confused with other pathologic processes, such as infection or malignancy. However, CADD has typical imaging characteristics that usually allows for a correct diagnosis to be made without additional imaging or laboratory workup, even when presenting in unusual locations. This is a review of the common and uncommon presentations of CADD in the appendicular and axial skeleton as well as an updated review of pathophysiology of CADD and current treatments.

“…Periarticular calcium deposits have also been linked to acute compression of the ulnar nerve at the Guyon canal. 31 The patient's history and electrodiagnostic studies can help the clinician distinguish between these conditions and isolated distal ulnar dysfunction.…”

Presentation of ulnar nerve entrapment at the wrist varies based on differential anatomy and the site or sites of compression. Therefore, an understanding of the anatomy of the Guyon canal is essential for diagnosis in patients presenting with motor and/or sensory deficits in the hand. The etiologies of ulnar nerve compression include soft-tissue tumors; repetitive or acute trauma; the presence of anomalous muscles and fibrous bands; arthritic, synovial, endocrine, and metabolic conditions; and iatrogenic injury. In addition to a thorough history and physical examination, which includes motor, sensory, and vascular assessments, imaging and electrodiagnostic studies facilitate the diagnosis of ulnar nerve lesions at the wrist. Nonsurgical management is appropriate for a distal compression lesion caused by repetitive activity, but surgical decompression is indicated if symptoms persist or worsen over 2 to 4 months.
