Background <p>Bariatric surgery may offer hope for long-term weight control in individuals with special needs. Arthrogryposis Multiplex Congenita can complicate anaesthesia management in obesity due to difficult airway, decreased lung function, positioning limitations, vascular access difficulties, and differences in postoperative pain management. We present our anaesthesia management for an obese patient with Arthrogryposis Multiplex Congenita undergoing bariatric surgery.</p> Case presentation <p>A 25-year-old male patient diagnosed with Arthrogryposis Multiplex Congenita (AMC) presented for bariatric surgery. During the preoperative anaesthesia assessment, the risk of Obstructive Sleep Apnoea Syndrome (OSAS) was evaluated as high risk using the STOP BANG questionnaire. Perioperative management was meticulously provided to address the risks of hypoventilation and malignant hyperthermia.</p> Conclusions <p>AMC complications can further complicate anaesthesia management in bariatric surgery.</p>
