Neonatal Limb Compartment Syndrome: A Comprehensive Review.

Purpose: Neonatal limb compartment syndrome (NLCS) is a rare and potentially limb-threatening condition defined as an increased pressure within a confined limb compartment. Clinicians may fail to distinguish NLCS from other mimicking conditions. Misdiagnosis is possible due to a low index of suspicion for this condition, which may delay appropriate and urgent treatment. A comprehensive review of the available literature was performed to explore common themes in NLCS and identify gaps in the evidence to guide future studies.

Methods: A literature search was conducted in PubMed, Scopus, and Google Scholar electronic databases to identify original articles and reviews in English or French. Studies were selected by two independent reviewers who extracted descriptive data including the delivery history and complications, the timing of diagnosis, the location of the lesion, and the management strategy.

Results: A total of 43 reports describing 86 cases of neonatal compartment syndrome were published between 1980 and 2021. The male-to-female ratio was 6:7. Compartment syndrome was mainly located in the upper extremity (95.3%). Clinical features including swelling (41%), sentinel skin lesion (94.2%), extremity cyanosis (89.5%), and necrotic fingers (7%) were observed. The treatment strategy was either surgical decompression (32.6%) or nonsurgical management (68.6%). Sequelae occurred at a rate of 16.6%, 81.3%, and 75.9% after early fasciotomy (< 24 hours), late fasciotomy, and nonsurgical management, respectively.

Conclusions: Sentinel skin lesions and flaccid paralysis are the most observed clinical features and represent key clues for diagnosis. Neither radiography, Doppler ultrasound, nor magnetic resonance imaging has demonstrated any advantage in guiding the appropriate management of NLCS and may delay appropriate treatment. Despite nonsurgical management and late fasciotomy (> 24 hours) being the most described treatments, the lowest rate of sequelae was observed when decompression was performed within the first 24 hours.
