ObjectiveTo review the research progress in the treatment of proximal humeral fractures with fibular allograft and locking plate.MethodsThe literature about the treatment of proximal humeral fractures with fibular allograft and locking plate was reviewed and analyzed from the aspects such as the biomechanics, imaging prognosis, and clinical prognosis.ResultsFibular allograft and locking plate can provide effective medial support for proximal humeral fracture and increase the strength of internal fixation system. Compared with locking plate, fibular allograft combined with locking plate can maintain better humeral neck-shaft angle and the humeral head height after operation in the treatment of proximal humeral fractures, and has better shoulder mobility and shoulder joint function, and does not increase the risk of complications.ConclusionFibular allograft combined with locking plate may be a new and effective treatment for proximal humeral fractures. However, the long-term follow-up results are insufficient, the final outcome of fibula is uncertain, and the long-term potential adverse reactions caused by this treatment are still indefinite.
