Prognosis [ 7, 9 ] Many patients improve with nonsurgical treatments (above). Results of reconstructive surgery have been shown to be variable, with fairly common recurrence. [patient.info]

Non-surgical treatment is considered sufficient, particularly in the setting of vasospasm with adequate collateral circulation. [radiopaedia.org]

Therefore, conservative treatment or bypass of the thrombosed vessels is possible in hypothenar hammer syndrome. [handsurgeryresource.com]

Prevention Improve work practices so as to avoid using the palm of the hand as a hammer. Occupational screening (where relevant) has been advocated, since some degree of ulnar arterial damage may occur preclinically. [ 2 ] [patient.info]

Conclusions As described above, hypothenar hammer syndrome may not be as rare as once thought. 27 It is a curable and preventable cause of upper extremity digital ischemia. [ncbi.nlm.nih.gov]
