Lumbosacral radiculopathy, reflex sympathetic dystrophy and tarsal tunnel syndrome: an unusual presentation.
This case documents a patient with lumbosacral radiculopathy, reflex sympathetic dystrophy, and tarsal tunnel syndrome affecting one extremity. After lumbar laminectomy for L5-S1 radiculopathy, the patient developed foot pain diagnosed as secondary to reflex sympathetic dystrophy. Because of increasing foot pain despite long-term conservative therapy, the patient underwent further evaluation, including electrodiagnostic studies leading to the diagnosis of a superimposed tarsal tunnel syndrome. Following surgical decompression, pain decreased. Because of the unusual presentation, diagnosis and treatment of the tarsal tunnel syndrome was significantly delayed. To help understand the coexistence of these conditions, interrelating pathophysiologic mechanisms have been postulated, including the possibility that a "double-crush" phenomenon may have contributed to the development of tarsal tunnel syndrome. Earlier diagnosis and definitive treatment of the foot pain may have been possible had these mechanisms been better understood.
