Background: Nerve reconstruction techniques for lumbosacral plexus (LSP) injuries vary. There are no clear treatment guidelines available, and summative evaluations of the literature discussing these surgeries are lacking. For these reasons, this investigation aimed to systematically review and consolidate all available literature discussing surgical interventions for LSP injuries and cohesively present patient-reported and objective postoperative outcomes. Methods: The authors conducted a systematic review using PubMed, Embase, Web of Science, ProQuest Dissertations and Theses Global (via Proquest.com), and ClinicalTrials.gov databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. After title and abstract screening, identified articles were read in full and selected for inclusion based on prespecified criteria. Results: Our literature search identified 8683 potential citations, and after duplicate removal, abstract screening, and full-text review, 62 studies remained meeting inclusion and exclusion criteria. Outcomes were extracted according to the location of injury and type of surgical repair. Injuries were classified into isolated femoral nerve injuries, isolated obturator nerve injuries, isolated sciatic nerve injuries, and multilevel LSP injuries. Surgical treatment was further classified into exploration with neurolysis, direct repair, nerve grafting, and nerve transfer surgery. Conclusions: Although results vary based on the location of the injury and the surgical technique used, nerve grafts and transfers demonstrated reasonable success in improving functional and pain outcomes. Overall, isolated femoral and obturator nerve injuries had the best outcomes reported with surgical treatment. Furthermore, incomplete sciatic nerve and multilevel LSP injuries had more reported surgical options and better outcomes than complete sciatic nerve injuries.

BACKGROUND: Sole sensation is essential for standing and walking. Moreover, lack of protective sensation of sole increases the risk of fall-related injuries. In the light of recent developments in nerve transfer, reconstruction of sole sensation can be achieved even in sciatic nerve injuries. Few researchers have addressed the problem of lack of potential donor nerve in proximal sciatic nerve injuries. The saphenous nerve has sufficient sensory fibers and is anatomically feasible to be used as a donor nerve to reconstruct sensation. OBJECTIVE: To outline a new approach to restore the sensation of the sole using terminal branches of the saphenous nerve. METHODS: In an attempt to restore sole sensation, 4 patients underwent saphenous nerve transfer to medial plantar and calcaneal branches. Highet-Zachary system scoring was used to evaluate sensory recovery in target regions (heel, metatarsal heads, and big toe). RESULTS: Of the study population, heel sensation recovered up to S3 in 1 case, S2 in 2 cases, and S1 in 1 case. Partial recovery of the metatarsal heads and the big toe was achieved in 2 cases. CONCLUSION: The findings of this study indicate that the saphenous nerve is a suitable and available donor to restore sole sensation in sciatic or posterior tibial nerve injuries.
