What hand surgery loupes need to do
The hand is small. Every structure of clinical interest — flexor tendons, digital nerves, neurovascular pedicles, articular surfaces — is measured in millimeters. The suture sizes match: 4-0 for tendon core, 6-0 to 7-0 for epitendinous repair, 8-0 to 10-0 for microvascular work. Loupe magnification for hand surgery is not about extracting marginal precision — it is about being able to see the work at all.
