Introduction: Managing Diabetic Foot Injuries

A 55-year-old man presented at Leading Edge Podiatry with a wound on his right foot. The patient had a history of type 2 diabetes. He has not seen a podiatrist before. He reported he noticed his skin peel off as he removed his sock the night before. He wonders if he accidentally burnt his right foot against a radiator heater at home, unaware of the injury.

Patient’s Medical History: Diabetes and Neuropathy

The patient had been diagnosed with type 2 diabetes ten years ago, and after his diagnosis, he developed peripheral neuropathy. His diabetes management included oral hypoglycemic medications and routine monitoring of blood glucose levels. The patient had a history of mild hypertension but no other significant medical conditions. He was a non-smoker and occasionally consumed alcohol in moderation.

Foot Wound Description: Diabetic Complications

The patient described the initial incident as accidental contact with a heater, resulting in a burn on the sole of his right foot. However, due to the diminished sensation caused by neuropathy, he was unaware of the severity of the injury. The wound, located over the metatarsal region, appeared as an open ulcer with surrounding erythema and mild swelling. The patient denied any systemic symptoms such as fever or malaise.

Examination and Assessment of the Diabetic Foot Wound

The podiatrist conducted a thorough examination, considering the patient’s diabetic status and neuropathic condition. Sensory testing using a monofilament confirmed no sensation in both feet, consistent with diabetic neuropathy. The wound was probed to assess its depth and the potential involvement of underlying structures. It appears superficial with no clear signs of infection.

Imaging Studies

Imaging studies, including X-rays and Doppler ultrasound, were ordered to evaluate for any underlying osteomyelitis or compromised vascular supply. Results indicated no bone involvement but did highlight diminished blood flow to the affected foot.

Diagnosis and Treatment Plan for Diabetic Foot Ulcers

The patient was diagnosed with a diabetic foot wound resulting from a thermal injury, compounded by neuropathy. The treatment plan focused on wound care, infection management, and offloading to facilitate healing. Daily wound dressings with antimicrobial agents were initiated, and the patient was instructed on proper foot hygiene.

Referral and Multidisciplinary Approach

Due to the risk of infection and compromised blood flow, he was referred to a local public hospital for a multidisciplinary approach involving a vascular specialist and endocrinologist. The patient’s diabetes management was optimised, and he was provided with education on foot self-examinations and protective measures.

Offloading Measures

Offloading measures, including the use of a removable cast walker, were recommended to reduce pressure on the affected foot and promote optimal healing conditions. The patient was advised to refrain from bearing weight on the affected foot whenever possible.

Follow-Up Care for Diabetic Foot Health

The patient was scheduled for regular follow-up appointments to monitor wound progress, assess glycaemic control, and address any concerns. The podiatrist emphasised the importance of ongoing foot care and the need for prompt medical attention in case of any changes in the wound, signs of infection, or new symptoms.

Conclusion: Importance of Early Detection and Collaborative Care in Diabetic Foot Health

This case underscores the challenges faced by middle-aged individuals with diabetes, neuropathy, and the potential for foot injuries. The podiatrist’s role in early detection, wound management, and collaborative care with other specialists is vital in preventing complications and promoting optimal foot health in diabetic patients.
