Type 1 Complex Regional Pain Syndrome After Subacromial Shoulder Surgery: Incidence and Risk Factor Analysis

Successful therapy of complex regional pain syndrome after hip arthroscopy for femoroacetabular impingement syndrome: a case report

BACKGROUND

Complex regional pain syndrome is a neuropathic pain disorder associated with ongoing pain that persists beyond the usual expected tissue healing time and that is disproportionate to the degree of tissue injury present. Complex regional pain syndrome after hip arthroscopy has not been reported before. Hip arthroscopy is a fast-growing domain that could lead to an increasing number of complex regional pain syndrome cases, probably owing to the high traction forces that are necessary.

CASE PRESENTATION

We report the case of a 30-year-old German female semiprofessional tennis player who presented with complex regional pain syndrome type I in the lower leg 3 weeks after hip arthroscopy for femoroacetabular impingement syndrome with suture anchor labral repair and femoroplasty. After 2 months of immediate multimodal conservative therapy including administration of gabapentin, prompt full weight-bearing, and intensified physiotherapy, complete recovery was achieved.

CONCLUSION

Complex regional pain syndrome does occur after elective hip arthroscopy. Disproportionate postoperative pain or other symptoms raising suspicion of complex regional pain syndrome should be promptly evaluated and treated through a multimodal approach. Postless hip arthroscopy may be advantageous.

Perioperative anaesthetic considerations for rotator cuff repair surgeries: A current concept review

Surgeries for Rotator Cuff (RC) pathologies are required for either trauma or degenerative related aetiologies. Various surgical techniques from open to arthroscopic repair, are being undertaken by orthopaedic surgeons. Peri-operative anaesthetic management of the patients undergoing rotator cuff repair requires understanding the surgical procedure and patient status for optimal anaesthetic planning. Such management mandates a thorough pre-operative evaluation, including clinical history, examination, and relevant investigations. Patients with acute trauma associated Rotator Cuff (RC) tears should be assessed for visceral injuries using appropriate injury evaluation systems before such repairs. On the other hand, patients with degenerative tears tend to be older with associated comorbidities. Hence pre-operative optimisation is necessary according to risk stratification. Anaesthetic techniques for Rotator Cuff (RC) surgery include general anaesthesia or regional anaesthesia. These are individualised according to patient assessment and surgical procedure planned. Knowledge of relevant surgical anatomy is essential for intra-operative, and post-operative neural blockade techniques since optimal peri-operative analgesia improve overall patient recovery. The occurrence of a peri-operative complication should be recognised as timely management improves the patient-related surgical outcomes. We describe the relevance of surgical anatomy, the effect of patient positioning, irrigating fluids, various anaesthetic techniques and an overview of regional and medical interventions to manage pain in patients undergoing for Rotator Cuff (RC) surgery.
