Managing the open calcaneal fracture: A systematic review

Introduction: Open fractures of the calcaneus are rare. They are mostly caused by high-energy trauma. There are several treatment options for calcaneal fractures. However, treatment of open calcaneal fractures might need a different approach, as open calcaneal fractures are associated with high rates of complications. The purpose of this study was to provide a literature overview on the management of open calcaneal fractures, and deduct a more standardized treatment algorithm. Material and methods: A literature review was conducted in the databases of PubMed, EMBASE and the Cochrane Library for articles describing the management of open calcaneal fractures. Excluded were studies with less than 10 patients, studies describing combat injuries and reviews. Only articles published from 1998 to 2017 were included and there were no language restrictions. Results: A total of 18 articles were included with 616 open calcaneal fractures in 598 patients. Most wounds were Gustilo grade III and most fractures were Sanders type III. Definitive surgery was performed after a mean of 9.8 days and in most cases in the form of ORIF via ELA. The complication rate was 21% and the mean AOFAS score was 73.7 points. Conclusion: The complication rates of open calcaneal fractures are high and increase with the severity of the wound. A treatment algorithm is suggested. However, to produce a more evidence-based protocol and achieve consensus for treatment, additional research should be done, preferably in the form of a prospective multicenter database

Assessment of disability in idiopathic inflammatory myopathy: a call for linearity

OBJECTIVES: To evaluate the clinimetric properties of the Academic Medical Centre Disability Score (ALDS) in patients with idiopathic inflammatory myopathy (IIM). METHODS: We used prospectively collected data of IIM patients who completed a phase-2 study with first-line IVIG monotherapy. The ALDS is a patient-reported questionnaire which contains 25 items relevant for disability in myositis. ALDS and all core set measures (CSMs) for myositis [including HAQ-Disability Index (HAQ-DI)] were evaluated at baseline and 9 weeks follow-up. In addition, the 2016 ACR/EULAR myositis response criteria outcome called Total Improvement Score (TIS) was evaluated at 9 weeks. We examined floor/ceiling effects, reliability and construct validity of the ALDS. To examine known-group validity, ALDS change scores over time were compared with TIS and physician impression of clinical response. RESULTS: Nineteen patients with IIM [median age 59 years, 12 (63%) female] were enrolled. At baseline, ALDS showed a median score of 65.4 (IQR 58.2-73.5), good Cronbach's alpha (α = 0.84) and a small ceiling effect (11%). Construct validity was confirmed by moderate to strong correlations between ALDS and HAQ-DI [rs = -0.57 (baseline); -0.86 (follow-up)]. ALDS change score correlated with TIS (rs = 0.70), discriminated between responders and non-responders (TIS ≥ 40; P = 0.001), between groups based on physician impression of clinical response (P = 0.03), and detected deterioration. CONCLUSION: The ALDS showed promising clinimetric properties and detected relevant changes in disability in patients with myositis. These results warrant further investigations
