Pain after ortho-plastic reconstruction of lower limb injuries: A snapshot study.

Introduction: The incidence of pain after flap reconstruction of complex lower limb injury is poorly reported in the literature, and yet represents a significant source of morbidity in these patients. In our centre (Southmead Hospital, Bristol, England) patients who have had flap reconstruction for complex lower limb injury are followed up at a joint ortho-plastics lower limb clinic run weekly. The aim of this study was to report the incidence of pain in such patients at follow-up in the specialist clinic. The impact of the experience of pain upon the quality of life, and the efficacy of analgesia was assessed these cases.

Patients And Methods: This was a cross sectional snapshot study of a cohort of complex lower limb patients attending our lower limb ortho-plastics outpatient clinic between the dates of: 17/5/16 and 28/6/16. Any patient attending clinic with previous flap reconstruction for lower limb injury was asked to complete the BPI (Brief Pain Index) questionnaire, and details regarding their injury and surgery were collected.

Results: There was a 100% response rate, with 33 patients completing the questionnaire. 28 out of the 33 patients (85%) reported ongoing pain. There was no significant relationship between time post operatively and average pain scores (Spearman's Rank R = 0.077), nor was there significant difference by age or gender. Over 25% of the patients with pain were not taking analgesia, however those using simple analgesia (paracetamol, NSAIDS) derived on average over 70% pain relief.

Conclusions: Pain in a common complication following flap reconstruction for complex lower limb injury reported in 85% of our cohort. This pain does not seem to be correlated with time, gender or age, and responds well to simple analgesia in most cases. This emphasises the importance of asking about pain at follow up, and taking simple measures to improve pain outcomes.
