Background: Surgical-site infection is a major concern in prosthetic-based breast reconstruction. Thirty-day postoperative readmission rates are a common quality metric, but little is known about readmission rates for later infections. Methods: Using the 2013 to 2014 Nationwide Readmissions Database, the authors identified breast cancer patients undergoing breast reconstruction with implants and tissue expanders who had an infectious readmission. The authors used univariate and multivariate logistic regression models to identify predictors of infectious readmission and explantation within the early (0 to 30 days) and late (31 to 90 days) postoperative periods. Results: In the weighted sample, the authors identified 18,338 patients undergoing prosthetic-based breast reconstruction. The overall infectious readmission rate was 4.1 percent (n = 759): 49.3 percent occurred early and 50.7 percent occurred late. Of the infectious readmissions, 39.5 percent required explantation, 55.1 percent of which occurred during a late infectious readmission. Seventy-five percent of these infectious readmissions and explantations occurred within 49 days of initial surgery. Median annual household income less than $40,000 (p = 0.035), diabetes (p = 0.038), and obesity (p = 0.004) were independent predictors of infectious readmission. Diabetes (p = 0.049) and hypertension (p = 0.011) were independent predictors of early readmission. Median annual household income less than $40,000 (p = 0.049), obesity (p = 0.006), and increasing length of stay during the index procedure (p = 0.028) were independent predictors of late readmission. No statistically significant independent predictors for explantation were identified. Conclusions: Traditional 30-day readmission rates are not an adequate quality metric for breast reconstruction given the number of late postoperative readmissions, many of which lead to explantation. Early and late infectious readmissions have different predictors. Interventions targeting these predictors may decrease the number of readmissions, thus reducing cost and improving quality. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Background Lower extremity trauma with soft tissue loss presents a challenge to the reconstructive surgeon. Cross-leg flaps, first described by Hamilton in 1854, are still used to salvage traumatized lower extremities in patients not suitable for free tissue transfer, or those who are receiving care in locations with limited resources. Methods A scoping review methodology was used to examine the evidence supporting the use of cross-leg flaps in modern healthcare. Results There have been 409 cases of cross-leg flaps reported in the modern literature, with the majority of flap cases occurring outside the United States in Turkey, India, and Japan. The most common indication was trauma, mentioned in 93.2% of patients (n = 353 of 379), and anatomic limitation, including inadequate vasculature, was the main reason for not performing free tissue transfer (52.8% of patients; n = 170 of 322). The majority are cross-leg fasciocutaneous flaps (85.8%, n = 273 of 318), based off the posterior tibial artery (27.5%, n = 50 of 182) and peroneal artery (26.9%, n =  49 of 182) and, covering defects of the distal third of the leg (55.5%, n = 151 of 272), or the foot (27.9%, n = 76 of 272). The pedicles are typically divided at 3 weeks (mean 20.9 days) after external fixation is used as the immobilization method (57.7%, n = 184 of 319). Flap survival was 100% across all publications except one (n = 349 of 350 patients), making cross-leg flaps a robust and reliable reconstructive option. Conclusion In resource-limited environments or in patients who are unsuitable for microvascular free tissue transfer, the cross-leg flap remains an impactful and reliable option for limb salvage.

Pelvic sarcoma resections present large and complex defects, which are a challenge to reconstruct. At times, these cancers are treated with external hemipelvectomy, and both the soft tissue and bony framework of the pelvic ring must be addressed. The purpose of this case report is to describe the use of a free tibia and fibula‐fillet‐of‐leg flap for pelvic ring reconstruction, performed to enhance the quality of life of a patient following hemipelvectomy. A 50‐year‐old female with advanced stage undifferentiated pleomorphic sarcoma of the left thigh and pelvis underwent free vascularized tibia and fibula‐fillet‐of‐leg flap, including 21 cm of bone length and 21 cm long and full circumferential soft tissues of the leg, accompanying the bone, for the reconstruction of the bony pelvis and soft tissue. Postoperatively, the patient had no surgical complications, was followed for 6 months and went on to have bony healing, and was able to sit prior to disease progression and eventual death from metastatic disease. In the reported case, we have shown that composite tibia–fibula free flap with lower leg soft tissues may be a viable option for the reconstruction of massive external hemipelvectomy defects.
