The Value of an Orthoplastic Approach to Management of Lower Extremity Trauma: Systematic Review and Meta-analysis.

[BACKGROUND] Management of traumatic lower extremity injuries requires a skill set of orthopedic surgery and plastic surgery to optimize the return of form and function. A systematic review and meta-analysis was performed comparing demographics, injuries, and surgical outcomes of patients sustaining lower extremity traumatic injuries receiving either orthoplastic management or nonorthoplastic management.

[METHODS] Preferred Reporting Items for Systematic Reviews and Meta-Analysis, Cochrane, and GRADE certainty evidence guidelines were implemented for the structure and synthesis of the review. PubMed, Embase, Cochrane Library, Web of Science, Scopus, and CINAHL databases were systematically and independently searched. Nine studies published from 2013 through 2019 compared 1663 orthoplastic managed patients to 692 nonorthoplastic managed patients with traumatic lower extremity injuries.

[RESULTS] Orthoplastic management, compared to nonorthoplastic management likely decreases time to bone fixation [standard mean differences: -0.35, 95% confidence interval (CI): -0.46 to -0.25, < 0.0001; participants = 1777; studies = 3; I = 0%; moderate certainty evidence], use of negative pressure wound therapy [risk ratios (RR): 0.03, 95% CI: 0.00-0.24, = 0.0007; participants = 189; studies = 2; I = 0%; moderate certainty evidence] with reliance on healing by secondary intention (RR: 0.02, 95% CI: 0.00-0.10, < 0.0001; participants = 189; studies = 2; I = 0%; moderate certainty evidence), and risk of wound/osteomyelitis infections (RR: 0.37, 95% CI: 0.23-0.61, < 0.0001; participants = 224; studies = 3; I = 0%; moderate certainty evidence). Orthoplastic management likely results in more free flaps compared to nonorthoplastic management (RR: 3.46, 95% CI: 1.28-9.33, = 0.01; participants = 592; studies = 5; I = 75%; moderate certainty evidence).

[CONCLUSION] Orthoplastic management of traumatic lower extremity injuries provides a synergistic model to optimize and expedite definitive skeletal fixation and free flap-based soft-tissue coverage for return of extremity form and function.
