"Laurin-Sandrow Syndrome - a review of the literature and classification system".

INTRODUCTION

Laurin-Sandrow syndrome also known as tetramelic mirror-image polydactyly is a rare congenital disorder characterized classically by polysyndactyly of the hands, mirror feet and nose anomalies (hypoplasia of the nasal alae and short columella) often associated with ulnar and/or fibular duplication. As a pathologic entity, it is heterogeneous, the patients displaying a variety of symptoms. This review aims to analyze the different aspects of the condition, such as clinical findings and methods of treatment to summarize the principal features of Laurin-Sandrow syndrome.

MATERIALS AND METHODS

The review is based on searches on PubMed, Web of Science and Researchgate of the following terms: "Laurin-Sandrow syndrome", "mirror hands", "mirror feet", "tetramelic mirror-image polydactyly", "fibular dimelia" and "ulnar dimelia". Clinical cases, reviews and original articles were included.

RESULTS

As a consequence of our findings, we suggest a modification of the Al-Qattan classification system for Mirror Hand-Multiple Hand Spectrum.

CONCLUSION

Even though it has an extremely low incidence, a thorough understanding of the syndrome enables the surgeon to choose the appropriate treatment with the ultimate goal to improve the patient's life quality.
