Osteocutaneous Radial Forearm Flap: Harvest Technique and Prophylactic Volar Locked Plating.

Background: The osteocutaneous radial forearm (OCRF) flap is a variation of the traditional radial forearm flap with incorporation of an anterolateral segment of corticocancellous bone of the radius, periosteum, and overlying skin. The OCRF flap is indicated in traumatic injuries or extirpation defects with segmental bone loss and is well suited to foot and ankle reconstruction due to its thin pliable skin. Methods: In this single-center case series, a retrospective review was conducted to identify patients who underwent OCRF free flap for foot and ankle reconstruction that required harvest of more than 50% of the cross-sectional area of the radius with prophylactic volar locked plating of the donor site. Outcome measures included flap failure rates, postoperative fracture, thrombotic events, time to follow-up, and time to full weightbearing. Flap harvest technique is extensively discussed. Results: Six cases were included in this series. There were no flap failures or thrombotic events. Recipient site healing was confirmed in all patients, with partial distal skin paddle loss in one patient requiring operative debridement. No patients sustained donor site complications or functional impairment. Full lower extremity weightbearing was achieved at 12.4 ± 3.3 weeks after surgery. Conclusions: The OCRF free flap transfer provides a reliable means of obtaining thin, supple soft tissue coverage with a large, vascularized segment of bone for reconstruction in the foot and ankle. Here, we describe use of more than 50% of the cross-sectional area of the radius with volar locked prophylactic plating. These updates expand use of this reconstructive technique.

Predictors of Mortality and Revision Following Digital Amputation for Infection and Necrosis.

PURPOSE: Digital amputation is a commonly performed procedure for infection and necrosis in patients with diabetes, peripheral vascular disease (PVD), and on dialysis. There is a lack of data regarding prognosis for revision amputation and mortality following digital amputation in these patients. METHODS: All digital amputations over 10-year period (2008-2018) at a single center were reviewed. There were 484 amputations in 360 patients, among which 358 were performed for trauma (reference sample) and 126 for infection or necrosis (sample of interest). Patient death and revision were determined from National Vital Statistics System and medical records. Propensity score matching was performed to compare groups. Data were then compared to the Social Security Administration Actuarial Life Table for 2015 to determine age-matched expected mortality. RESULTS: The 2-year revision rate was 34% for amputations performed for infection or necrosis, compared to 15% for amputations due to trauma. For amputations performed for infection or necrosis, the revision rate was 47.7% when diabetes, PVD, and dialysis were present. Among all patients with infection or necrosis (n = 104) undergoing a digital amputation, overall survival at 2, 5, and 10 years was 79.4%, 57.3%, and 17.5%, respectively, which represented a 3.2-fold increased risk of death compared to controls. (hazard ratio, 3.19; 95% confidence interval, 1.47-6.93). For amputations due to trauma, mortality was no different from that in the age-matched general population. CONCLUSIONS: Mortality and revision risk are high for patients requiring a digital amputation for infection or necrosis and are further increased with medical comorbidities. Hand surgeons should consider the prognostic implications of these data when counseling patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Long-term effects of a diabetes boot cAMP on measures of diabetic care.

BACKGROUND: Diabetic patients should receive self-management education to improve self-care and quality of life but are frequently unable to attend such programs because of the time commitment. We instituted an intensive 2-hour Diabetes Boot Camp to provide this education in a condensed time frame. The objective was to determine the long-term effect of the boot camp on mean hemoglobin A1c (HgA1c) levels in patients with diabetes compared to diabetic patients receiving the standard of care. METHODS: The Diabetes Boot Camp population was defined as all diabetic patients referred to the boot camp from the 10 highest utilizing physicians between August 2009 and August 2010. A control population was randomly selected from these same physicians' diabetic patients during the same period. Baseline and postintervention HgA1c measurements on the same patients in both groups were extracted from the electronic medical record. Subpopulations studied included those with HgA1c ≥9% and <9% at baseline. To evaluate long-term effects, we compared HgA1c levels 3 years later (between July 1, 2012 and December 31, 2012) for all groups. RESULTS: Using comparison-over-time analysis, the overall boot camp group (n=69) showed a mean decrease in HgA1c from 8.57% (SD ± 2.32%) to 7.76% (SD ± 1.85%) vs an increase from 7.92% (SD ± 1.58%) to 8.22% (SD ± 1.82%) in the control group (n=107, P<0.001). Mean length of follow-up was 3.2 (SD ± 0.54) years. CONCLUSION: An intensive 2-hour multidisciplinary diabetes clinic was associated with significant long-term improvements in glycemic control in diabetic participants of the clinic.
