Long-term functional outcome of secondary shoulder surgery in brachial plexus birth palsy patients a systematic review

Abstract

Aims Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BpBp) patients. the long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options. Methods a systematic literature search in healthcare databases (pubMed, embase, the Cochrane library, Cinahl, and Web of science) was performed from January 2000 to July 2020, according to the preferred reporting items for systematic reviews and Meta-analysis guidelines. the quality of the included studies was assessed with the Cochrane rOBins-i risk of bias tool. Relevant trials studying BPBP with at least five years of follow-up and describing functional outcome were included. results Of 5,941 studies, 19 were included after full-text screening. a total of 15 surgical techniques were described. all studies described an improvement in active external rotation (range 12° to 128°). A decrease in range of motion and Mallet score after long-term (five to 30 years) follow-up compared to short-term follow-up was seen in most studies. Conclusion the literature reveals that functional outcome increases after different secondary procedures, even in the long term. due to the poor methodological quality of the included studies and the variations in indication for surgery and surgical techniques described, a consensus on the long-term functional outcome after secondary surgical procedures in BpBp patients cannot be made.
