Abstract
Introduction
Diabetes is increasing on a global scale. By 2030, 10% of the global population, ½ billon people, are predicted to have diabetes. Potentially there will be a corresponding increase in number of patients referred for surgery.
Traditional surgical management of these patients is challenging.
Presented is a case series utilizing Minimally Invasive Surgical Techniques of percutaneous metatarsal neck osteotomies, metatarsal head debridement, mid-foot closing-wedge osteotomies and hind-foot arthrodesis, for the surgical management of diabetic foot pathology.
The potential socio-economic benefits analysis with regards to reduction in out-patient and theatre time, patient length of stay and time to healing are also postulated.
Methods
Minimally Invasive Surgical Techniques of metatarsal neck osteotomy, metatarsal head debridement, closing wedge osteotomy, mid-fusion and hind-foot arthrodesis nailing are described.
Procedures are preformed as day cases with fluoroscopic guidance. Low speed, high torque burrs and wedges, create the osteotomies, which can be held with percutaneous fixation.
Comparative cost analysis of conservative treatment, including clinic visits, out-patient debridement, dressings, intravenous and oral antibiotics, versus Minimally Invasive Surgical Techniques is presented.
Results
Six patients had metatarsal osteotomies for mechanical ulceration. Five reported good outcome. One patient required revision to forefoot arthroplasty due to mal-union. Five patients had debridement of metatarsal heads, which healed on average at six to eight weeks. Eight patients had mid-foot arthrodesis. Two infected cases required removal of metalwork. Three patients had hind-foot arthrodesis for arthritis following ankle fracture with degeneration and deformity.
Patients had good short and early medium term outcomes, with no reports of below-knee amputation. This technique is reproducible once the initial learning curve is mastered.
Comparative cost analysis, suggests significant financial savings by reducing inpatient admissions, clinic visits and theatre time.
Conclusion
Minimally Invasive Surgical Techniques may provide an alternative surgical management for diabetic patient with foot and ankle pathology.
