Syndrome du tunnel cubital et paraostéoarthropathie neurogène. À propos de huit cas

Posttraumatic Compressive Neuropathy of the Deep Motor Branch of the Ulnar Nerve Caused by Heterotopic Ossification

“…Heterotopic ossification has been described as a cause of peripheral neuropathy including compression of the ulnar nerve proper. Fikry et al 6 published a case series of eight patients who sustained head injuries and developed elbow ankylosis and associated cubital tunnel syndrome due to ulnar nerve entrapment in heterotopic bone. Ulnar neuropathy has also been reported due to heterotopic ossification at the elbow after stroke and burns that caused encircling of the ulnar nerve within a bony tunnel.…”

Surgical treatment of tardy ulnar nerve palsy due to non-neurogenic heterotopic ossification in the elbow

“…Compressive ulnar neuropathy caused by HO of the elbow joint is rare. [8][9][10][11][12] Regarding anatomical features of the elbow joints, the ulnar nerve passes through a narrow cubital tunnel wrapped around the supra-epitrochlear and surrounding tissues. If HO occurs medially or posteromedially at the elbow joints, ulnar nerve compression is possible.…”

“…However, HO at the elbow rarely causes neurological symptoms through ulnar nerve compression. [7][8][9][10][11][12] We performed surgical treatment for patients with rare tardy ulnar nerve palsy caused by HO of the elbow joint and evaluated their clinical outcomes. The results are presented here, along with a literature review.…”

Heterotopic Ossification Complicating Traumatic Ulnar Nerve Palsy in a Child

“…All cases underwent early surgical release and transposition of ulnar nerve with good to excellent outcomes in seven of eight patients. 14 Brooke et al 15 reported a case of ulnar nerve compression due to HO in a major burn patient which appeared 3 months after his burn. He was treated by early surgical release of HO and anterior transposition of ulnar nerve with good nerve recovery.…”
