The Size of Calcaneus in Koreans / 대한족부족관절학회지

PURPOSE: Open reduction and internal fixation of calcaneal fracture using plate has been used. While numerous plates have been manufactured, most of the conventional plates are designed for westerners, realistically the size is larger for Korean. The domestic products, on the other hand, often have the undesirable screw holes and path. Therefore, we measured the radiologic parameter of Korean calcaneus for providing the plate and screw hole placements. MATERIALS AND METHODS: We measured the outer lines and angles with over the 20 years old 291 females and 322 males. A: Length of inferior plane of calcaneus, B: Length of anterior plane of calcaneus, C: Length from line A to sinus tarsi, D: Length from line A to posterior point of posterior facet, E: Length from line A to calcaneal tuberosity, F: Length of posterior facet, G: Length from anterior point of line A to C, H: Length from line C to line D, a: Angle between A and B, b: Gissane angle, c: Bohler angle, d: Calcaneal pitch angle using Marosis m-view(R). RESULTS: Mean A, B, C, D, E, F, G, H were 63.6, 26.4, 23.2, 43.7, 40.5, 26.9, 12.8, 18.1 mm. Mean a, b, c, d angle were 105.8, 122.4, 32.4, 20.5degrees. Male's calcaneus is significantly bigger than female's (p<0.001). CONCLUSION: AP calcaneus length 63.6 mm, maximal height 43.7 mm is considered to be helpful in making the Korean calcaneal plate.

Breakage of Reamer during Tibia Intramedullary Nailing: A Case Report

The reamer crack, followed by breakage at its distal part occurred during intramedullary nailing of tibial shaft fracture. The broken reamer was trapped in the intramedullary canal, making it very difficult to pull out. We successfully extracted the broken reamer by retrograde impaction through the fracture site and completed intramedullary nailing procedure. Thus, we present this case with a review of the literature.
