Entrapment and compartment syndromes of the upper limb in haemophilia.

17 patients with haemophilia have been treated for a neurological deficit of the upper limb. Four of the five entrapment neuropathies have been operated upon, and only two patients recovered completely. Only two of the 12 patients with a compartment syndrome have been operated upon, and only two had sequelae. Clotting factor replacement is always indicated as primary treatment. Surgical release is indicated if the condition fails to improve. Late treatment was responsible for incomplete recovery, whatever the cause of the nerve compression.
