Compression neuropathy: a late finding in the postburn population: a four-year institutional review

Abstract

Nerve compression syndromes may cause postburn morbidity that can often be difficult to recognize and manage. This study reviewed patients in the authors' institution who needed nerve decompression secondary to thermal or electrical burns. The objective was to evaluate the timing of nerve decompression in the burn population. A 4-year review of the authors' institution's database found 22 patients who underwent peripheral neuroplasty. This patient population included both thermal and electrical burn patients. Two patients were excluded from the study because they underwent rapid forearm amputation, and a third patient who had his initial burn care done in Europe was also excluded. The authors reviewed the mechanism of burn: percentage of body surface area burned, which nerves underwent decompression, and time from burn to decompression. Nerve compression syndromes were diagnosed and treated in this group of patients from day 46 to 1530 post-burn. Carpal tunnel was the most common site of compression accounting for 46% of the nerve decompressions. Sixteen of the 19 (84%) patients required that synchronous nerves be decompressed. The average body surface area burn in the thermal group was 43 and 5% in the electrical burn group. Nerve compression syndromes secondary to burns can be a challenging problem to diagnose and treat. Multiple studies have shown the importance of treating nerve compressions in the acute setting; however, this study shows the importance of long-term surveillance, secondary to the late presentation of nerve compression syndromes. Late nerve compression neuropathies were present in both the electrical and thermal burn patients. The authors also found that presentation of a single nerve compression should raise the suspicion of a synchronous nerve compression. Patients with thermal burns greater than 20% body surface area and electrical burns should be routinely questioned and examined for the peripheral nerve compression syndromes during long-term follow-up.
