Gastrocnemius fascia release under local anaesthesia as a treatment for neuropathic foot ulcers in diabetic patients: a short series.

BACKGROUND: Diabetic foot ulceration is the leading cause of major amputation in the developed world. Plantar neuropathic ulcers at the forefoot can be managed conservatively with off-loading, but treatment is not invariably successful. Achilles tendon lengthening procedures aim at increasing dorsiflexion and decreasing forefoot pressure but can be associated with complications and require prolonged postoperative immobilization to prevent tendon rupture. We assessed the feasibility and clinical outcome of a comparative minimal invasive procedure: the gastrocnemius fascia release. This technique targets the same goals but is performed under local anaesthesia and allows immediate postoperative weight bearing and ambulation. METHODS: Diabetic patients with plantar neuropathic ulcers Wagner grade 2 or 3 were recruited from our diabetic foot clinic. Patients with infected wounds or untreatable peripheral arterial disease were excluded from the study. Conservative treatment with off-loading and local wound care was attempted for six weeks and surgical procedure only contemplated upon failure. Primary end-points were improved range of dorsiflexion and time to healing. Secondary end-points were local ulcer recurrences, new plantar ulcers, and minor or major amputation. Post-operative follow-up was 12 months. RESULTS: Seven patients were included in the study. An improvement in dorsiflexion of 10.4° (mean) was recorded post-operatively (p < 0.01). After 30 days, complete healing was accomplished in six of the seven patients. Long-term results were excellent as no ulcer recurrence or amputation was noted. CONCLUSIONS: Gastrocnemius fascia release under local anaesthesia can be performed safely in diabetic patients with plantar neuropathic ulcers under the metatarsal heads. Clinical outcome is excellent and long-term results promising.

Clostridium myonecrosis - a rare and underdiagnosed condition in the elderly: a case with severe skipping lesions and an overview of treatment guidelines.

We present an unusual and severe case of spontaneous clostridial myonecrosis (SCM) in an elderly patient, with severe skipping lesions spread throughout the body. CT imaging, combined with postmortem available blood cultures, confirmed the diagnosis. We noted an underrepresentation of SCM in the cohort of elderly patients (≥ 85 years), upon a review of case reports in the literature over the last decade. Given the worldwide demographic change resulting in an increase in the number of visits to emergency departments for this age group, it is likely that SCM is underdiagnosed in these elderly patients. This case report aims to increase awareness among emergency physicians to recognize the disease as well as to provide a treatment guideline, in order to provide better care and outcome.
