Study Design:
A retrospective follow-up study.
Objectives:
To review and analyze the sexual function of patients who have sustained lumbar fractures with incomplete paraparesis.
Summary Of Background Data:
As a result of advances in surgical techniques, most patients with lumbar fractures have significant recovery of neurologic status. Because motor functions are important to patients, most of the studies have concentrated their analyses on motor recovery. Many patients who have almost completely recovered motor function, however, may have sexual dysfunction, especially men.
Methods:
Forty-three patients with lumbar fractures that resulted in incomplete paraparesis were analyzed. American Spinal Injury Association motor index points were determined for each patient before and after surgery and used for comparison between American Spinal Injury Association motor index and international index of erectile function score. Eleven male patients who reported sexual dysfunction were evaluated by using Rigiscan.
Results:
During the follow-up period, 42 patients showed neurologic recovery. Average improvement of American Spinal Injury Association motor score was 13. 1 and average international index of erectile function score was 45. Average improvement of American Spinal Injury Association motor score for patients who had not reported sexual dysfunction was 12.5, and average international index of erectile function score was 52. For 11 patients in the sexual dysfunction group, preoperative motor score was 28.0, and average improvement of score was 14.9. Nocturnal penile tumescence monitoring results were abnormal in four cases. Averaged international index of erectile function score was 15. There was a statistically significant difference between the sexually healthy and dysfunctional groups in international index of erectile function score (P < 0.05), whereas no difference was noted in American Spinal Injury Association motor score.
Conclusions:
Neurologic recovery after lumbar fractures was improved. Regardless of neurologic recovery, most patients reported some disability, usually caused by pain and occasionally sexual dysfunction. Impairment of sexual function was present in four patients (9.3%). Although these patients may preserve psychiatric erection potential, they usually experienced sexual problems.
