We conducted a randomized controlled trial to compare pain scores and patient satisfaction between topical anaesthetic cream (5% lidocaine-prilocaine cream) versus placebo cream, applied approximately 90 minutes before local anaesthetic injection for open trigger digit release. One hundred participants were enrolled and randomly allocated into the two groups between May 2019 and February 2020. The visual analogue pain scores and satisfaction scores were measured. Most participants were female with Quinnell Grade 2-3 trigger digits. The pain scores during needle injection, local anaesthetic infiltration, the overall pain and satisfaction scores had no statistically significant differences between groups. There was no correlation between duration of topical anaesthetic drug application and pain scores. Subgroup analysis did not show significant differences in pain scores between genders. No complications were found during the study period. The topical anaesthetic drug was ineffective to use on the palmar skin during open trigger digit release surgery. Level of evidence: II.

Purpose: To report the midterm outcome of a novel reconstructive technique using a contoured iliac crest bone graft for partial radial head replacement in the treatment of complex elbow dislocation., Material and Methods: Between January 2008 and December 2013, 10 patients (5 women, 5 men; mean age, 43.8 years; mean follow-up duration, 65.9 months) with complex elbow dislocation who underwent the partial radial head replacement with the contoured bone graft were included in the study. The irreparable radial head defects averaged 49% of the articular surface (range, 36-60%). The fracture involved the entire head in four patients and partial head in six patients., Results: At the final follow-up, the mean elbow extension was 8°, flexion 143°, supination 76.5°, and pronation 73°. The mean Mayo elbow performance index was 93.2 points and the Broberg-Morrey functional rating score was 94.1 points, with seven excellent cases, two good cases, and one fair case. Radiographic union was achieved in all but one, at an average time of 6.89 weeks (range, 6-10 weeks). The final radiographs demonstrated no evidence of degenerative change in eight patients, mild arthritis in one patient, and moderate arthritis in one patient., Conclusion: This technique is a viable option in the treatment of the large radial head defect in complex elbow dislocation when more than 40% of the original head is still available for incorporation.
