Economic value of podiatry service in limb salvage alliance.

OBJECTIVE/BACKGROUND: Over the past decade, multidisciplinary "toe and flow" programs have gained great popularity, with proven benefits in limb salvage. Many vascular surgeons have incorporated podiatrists into their practices. The viability of this practice model requires close partnership, hospital support, and financial sustainability. We intend to examine the economic values of podiatrists in a busy safety-net hospital in the Southwest United States. METHODS: An administrative database that captured monthly operating room (OR) cases, clinic encounters, in-patient volume, and total work relative value units (wRVUs) in an established limb salvage program in a tertiary referral center were examined. The practice has a diverse patient population with >30% of minority patients. During a period of 3 years, there was a significant change in the number of podiatrists (from 1 to 4) within the program, whereas the clinical full-time employees for vascular surgeons remained relatively stable. RESULTS: The limb salvage program experienced >100% of growth in total OR volumes, clinic encounters, and total wRVUs over a period of 4 years. A total of 35,591 patients were evaluated in a multidisciplinary limb salvage clinic, and 5535 procedures were performed. The initial growth of clinic volume and operative volume (P < .01) were attributed by the addition of vascular surgeons in year one. However, recruitment of podiatrists to the program significantly increased clinic and OR volume by an additional 60% and >40%, respectively (P < .01) in the past 3 years. With equal number of surgeons, podiatry contributed 40% of total wRVUs generated by the entire program in 2019. Despite the fact that that most of the foot and ankle procedures that were regularly performed by vascular surgeons were shifted to the podiatrists, vascular surgeons continued to experience an incremental increase in operative volume and >10% of increase in wRVUs. CONCLUSIONS: This study shows that the value of close collaboration between podiatry and vascular in a limb salvage program extends beyond a patient's clinical outcome. A financial advantage of including podiatrists in a vascular surgery practice is clearly demonstrated.

Plantar Fat Grafting and Tendon Balancing for the Diabetic Foot Ulcer in Remission.

We report on the use of free fat grafting as a means of redistributing normal and shear stress after healing of plantar diabetic foot wounds. Although fat augmentation (lipofilling) has been described previously as an approach to supplement defects and prevent atrophy, including use as an adjunct to wound healing and to mitigate pain in the foot, we are unaware of any reports in the medical literature that have described its use in the high-risk diabetic foot in remission. An active 37-year-old man with type 2 diabetes and neuropathy presented with gangrene of his fifth ray, which was amputated. He subsequently developed a chronic styloid process ulceration that progressed despite treatment. We performed a tibialis anterior tendon transfer and total contact casting. He went on to heal but with residual fat pad atrophy and recalcitrant preulcerative lesions. We then used autologous fat grafting for the plantar atrophy. The patient was able to successfully transition to normal shoe gear after 4 weeks with successful engraftment without complication or recurrence of the wound at 6 weeks. This therapy may provide a promising adjunct to increase ulcer-free days to the patient in diabetic foot remission.

Split-thickness skin grafting the high-risk diabetic foot.

OBJECTIVE: The application of split-thickness skin grafts (STSGs) to chronic extremity wounds has often been considered undesirable because of the perceived high incidence of failure, especially in neuropathic patients with plantar diabetic foot wounds. The purpose of this study was to evaluate the outcomes of STSG placement in patients with chronic lower extremity wounds. METHODS: We abstracted data from consecutive patients at our institution from January 2007 through April 2013 who underwent STSG placement by vascular and podiatric surgeons for chronic wounds of the lower limb and foot. Patients were monitored for at least 24 weeks, unless the wounds healed sooner. RESULTS: There were 94 patients (72% male) in the study group, with a mean age of 61.0 ± 12.8 years. Of these, 66 patients had diabetes, including 13 who were dialysis-dependent; the remaining 28 had other chronic nondiabetic wounds. The average duration of follow-up was 12.0 ± 12.9 months. After STSG placement, 65 (69.1%) experienced complete graft incorporation and healing, and 18 (19.1%) required revision, five (5.3%) of whom ultimately required major limb amputation. There were no differences in healing when wounds in patients with and without diabetes or plantar vs nonplantar wound locations were compared (P > .05). Similar results were observed after adjusting the results for initial wound size. Although dialysis patients had a threefold higher rate of STSG revision (46.2% vs 14.8%; P = .01), the cumulative rate of wound healing as a function of time was independent of end-stage renal disease (P = .83). CONCLUSIONS: The results of this study suggest that STSG may be an effective method for promotion of wound healing in the management of chronic lower extremity wounds irrespective of wound location and presence of diabetes.

Utilization of advanced modalities in the management of diabetic Charcot neuroarthropathy.

Technological advances have allowed reconstructive foot and ankle surgeons greater opportunity to provide significant limb salvage options to those patients who present with significant lower extremity deformity due to diabetic Charcot neuroarthropathy. Paradigms that promote the utilization of these advanced modalities have demonstrated significant improved limb salvage outcomes in this challenging patient population and have consequently improved the quality of life for patients. The purpose of this review is to discuss current concepts in Charcot reconstruction.
