BACKGROUND: The malignant potential of the musculoskeletal tumors of the foot and ankle has often been underestimated because of their rarity. The current study reviewed the clinical features of the tumors of the foot and ankle, and evaluated the tumor size via imaging-based analysis to distinguish between benign and malignant lesions. METHODS: A retrospective review was performed using the clinical records of all patients with histologically confirmed musculoskeletal tumors of the foot and ankle, treated between 1998 and 2020 at our institution. We examined the distribution of tumors, rate of unplanned excision for primary surgery, and subsequent outcomes. In addition, the tumor size was examined via magnetic resonance imaging, and the cut-off value was determined via receiver operating characteristic (ROC) curve. RESULTS: A total of 103 bone and soft tissue tumors of the foot and ankle were included, of which 78 were soft tissue tumors and 25 were bone tumors. Of the 14 cases of malignant bone and soft tissue tumors, 6 (42.9%) received unplanned excision in the primary surgery, followed by amputation in 3 cases. Tumor size of malignant soft tissue tumors was significantly larger than that of benign soft tissue tumors (47.6 mm vs. 31.0 mm, respectively, P < .001). However, the difference between benign and malignant bone tumors was not statistically significant with the numbers available. ROC curve determined that the optimum diagnostic cutoff value for soft tissue tumor size was 40 mm, with a high area under the ROC curve 0.816 (95% CI: 0.711-0.921, sensitivity 91.7%, specificity 70.5%) CONCLUSIONS: We highlighted that bone and soft tissue tumors of the foot and ankle were often misdiagnosed and initially inadequately treated. We suggest that a cutoff value of 40 mm may be a useful index for prediction of malignancy in soft tissue tumors of the foot and ankle. LEVEL OF EVIDENCE: Ⅲ.

BACKGROUND: Manual evaluation is an important method for assessing ankle instability, but it is not quantitative. Capacitance-type sensors can be used to measure the distance on the basis of the capacitance value. We applied the sensor to the noninvasive device for measuring ankle instability and showed its utility. METHODS: First, 5 ankles embalmed by Thiel's method were used in an experiment using a cadaver. The capacitance-type sensor was fixed alongside the anterior talofibular ligament (ATFL) of a specially made brace, and the anterior drawer test was performed. The test had been performed for the intact ankle, with the ATFL transected and with both the ATFL and calcaneofibular ligament (CFL) transected. The anterior drawer distance was calculated by the sensor. Intra- and interinvestigator reliability were also analyzed.Next, as a clinical study, a brace with a sensor was fitted to 22 ankles of 20 patients with a history of ankle sprain. An anterior drawer test at a load of 150 N was conducted using a Telos stress device. The anterior drawer distances measured by the sensor and based on radiographic images were then compared. RESULTS: The mean anterior drawer distances were 3.7 ± 1.0 mm for the intact cadavers, 6.1 ± 1.6 mm with the ATFL transected (P < .001), and 7.9 ± 1.8 mm with the ATFL and CFL transected (P < .001). The intrainvestigator intraclass correlation coefficients (ICCs) were 0.862 to 0.939, and the interinvestigator ICC was 0.815. In the experiments on patients, the mean anterior drawer distance measured by the sensor was 2.9 ± 0.9 mm, and it was 2.7 ± 0.9 mm for the radiographic images. The correlation coefficient between the sensor and the radiographic images was 0.843. CONCLUSION: We quantitatively evaluated anterior drawer laxity using a capacitance-type sensor and found it had high reproducibility and strongly correlated with stress radiography measurements in patients with ankle instability. Capacitance-type sensors can be used for the safe, simple, and accurate evaluation of ankle instability.
