Video-assisted thoracoscopic surgery (VATS) aided full-length phrenic nerve transfer for restoration of elbow flexion.

BACKGROUND: In complete brachial plexus injury, phrenic nerve (PN) is frequently used in neurotization for elbow flexion restoration. The advancement in video-assisted thoracoscopic surgery (VATS) allows full-length PN dissection intrathoracically for direct coaptation to recipient without nerve graft. PURPOSE: We report our experience in improving the surgical technique and its outcome. METHODS: Seven patients underwent PN dissection via VATS and full-length transfer to musculocutaneous nerve (MCN) or motor branch of biceps (MBB) from June 2015 to June 2018. Comparisons were made with similar group of patients who underwent conventional PN transfer. RESULTS: Mean age of patients was 21.9 years. All were males involved in motorcycle accidents who sustained complete brachial plexus injury. We found the elbow flexion recovery were earlier in full-length PN transfer. However, there was no statistically significant difference in elbow flexion strength at 3 years post-surgery. CONCLUSION: We propose full-length PN transfer for restoration of elbow flexion in patients with delayed presentation.

Reliability of WhatsApp images of plain radiographs to diagnose fractures of the hand and wrist.

We assessed the reliability of plain radiographs interpreted through WhatsApp messaging system in orthopaedic hand trauma consultation in a large teaching hospital. Plain radiographs of 25 hand fractures and five normal radiographs were captured from a picture archiving and communication system using iPhone XS smartphone, anonymized and sent to 53 orthopaedic residents' and consultants' personal smartphones. The participants independently assessed the images and answered questions on fracture identification and characteristics, diagnostic confidence, further imaging and surgical inclination. The study was repeated after a 1-month washout period using the picture archiving and communication system on the hospital desktop. The results showed good (0.60 < ƙ < 0.80) intraobserver agreement on fracture identification and characteristics. The overall diagnostic accuracy for hand fractures was 95% on WhatsApp and 99% on the desktop. In conclusion, images of plain radiographs transmitted via WhatsApp were reliable for interpretation in orthopaedic hand trauma consultation.Level of evidence: IV.
