Healing of fracture nonunions treated with low-intensity pulsed ultrasound (LIPUS): A systematic review and meta-analysis
Bone fractures fail to heal and form nonunions in roughly 5% of cases, with little expectation of spontaneous healing thereafter. We present a systematic review and meta-analysis of published papers that describe nonunions treated with low-intensity pulsed ultrasound (LIPUS). Articles in PubMed, Ovi...

| description | Bone fractures fail to heal and form nonunions in roughly 5% of cases, with little expectation of spontaneous healing thereafter. We present a systematic review and meta-analysis of published papers that describe nonunions treated with low-intensity pulsed ultrasound (LIPUS).
Articles in PubMed, Ovid MEDLINE, CINAHL, AMED, EMBASE, Cochrane Library, and Scopus databases were searched, using an approach recommended by the Methodological Index for Non-Randomized Studies (MINORS), with a Level of Evidence rating by two reviewers independently. Studies are included here if they reported fractures older than 3 months, presented new data with a sample N≥12, and reported fracture outcome (Heal/Fail).
Thirteen eligible papers reporting LIPUS treatment of 1441 nonunions were evaluated. The pooled estimate of effect size for heal rate was 82% (95% CI: 77–87%), for any anatomical site and fracture age of at least 3 months, with statistical heterogeneity detected across all primary studies (Q=41.2 (df=12), p |

Thirteen eligible papers reporting LIPUS treatment of 1441 nonunions were evaluated. The pooled estimate of effect size for heal rate was 82% (95% CI: 77–87%), for any anatomical site and fracture age of at least 3 months, with statistical heterogeneity detected across all primary studies (Q=41.2 (df=12), p<0.001, Tau2=0.006, I2=71). With a stricter definition of nonunion as fracture age of at least 8 months duration, the pooled estimate of effect size was 84% (95% CI: 77%–91.6%; heterogeneity present: Q=21 (df=8), p<0.001, Tau2=0.007, I2=62). Hypertrophic nonunions benefitted more than biologically inactive atrophic nonunions. An interval without surgery of <6months prior to LIPUS was associated with a more favorable result. Stratification of nonunions by anatomical site revealed no statistically significant differences between upper and lower extremity long bone nonunions.
LIPUS treatment can be an alternative to surgery for established nonunions. Given that no spontaneous healing of established nonunions is expected, and that it is challenging to test the efficacy of LIPUS for nonunion by randomized clinical trial, findings are compelling. LIPUS may be most useful in patients for whom surgery is high risk, including elderly patients at risk of delirium, or patients with dementia, extreme hypertension, extensive soft-tissue trauma, mechanical ventilation, metabolic acidosis, multiple organ failure, or coma. With an overall average success rate for LIPUS >80% this is comparable to the success of surgical treatment of non-infected nonunions.</description><identifier>ISSN: 0020-1383</identifier><identifier>EISSN: 1879-0267</identifier><identifier>DOI: 10.1016/j.injury.2017.05.016</identifier><identifier>PMID: 28532896</identifier><language>eng</language><publisher>Netherlands: Elsevier Ltd</publisher><subject>Femur ; Fracture Fixation, Internal - methods ; Fracture Healing - physiology ; Fractures, Bone - physiopathology ; Fractures, Bone - therapy ; Fractures, Ununited - physiopathology ; Fractures, Ununited - therapy ; Humans ; Humerus ; Radius ; Randomized clinical trial (RCT) ; Randomized Controlled Trials as Topic ; Scaphoid ; Tibia ; Time Factors ; Treatment Outcome ; Ulna ; Ultrasonic Therapy - methods</subject><ispartof>Injury, 2017-07, Vol.48 (7), p.1339-1347</ispartof><rights>2017 The Authors</rights><rights>Copyright © 2017 The Authors.
