【正文】 f the biceps tendon to the FCR at the level of the wrist. This can then be used as a template for the incision line. 第四十二頁，共一百四十頁。 第四十三頁，共一百四十頁。 The incision is taken down through the skin, identifying the fascial layer with care taken not to damage any superficial veins that may be intact. The FCR tendon is clearly visible throughout the wound, as is the radial artery in the distal extent of the wound. FCR RADIAL ARTERY 第四十四頁，共一百四十頁。 A closeup of the distal aspect of the wound demonstrating The radial artery and its venous mtantes. RADIAL ARTERY AND VENOUS COMMTANTES 第四十五頁，共一百四十頁。 FCR RADIAL ARTERY The fascia on the radial side of the flexor carpi radialis is released, exposing the deep tissue. The radial artery can be followed now throughout the entire incision. 第四十六頁，共一百四十頁。 The radial artery may be taken in either direction, however, typically it is easier to take the artery to the radial side. FCR RADIAL ARTERY 第四十七頁，共一百四十頁。 The deep dissection is now performed between the flexorpronator mass on the ulnar side and the artery and the mobile wad on the radial side. 第四十八頁，共一百四十頁。 PRONATOR For the proximal dissection, the forearm is brought into supination and the pronator, FDS and FDP are released from the volar aspect of the radius 第四十九頁，共一百四十頁。 FDS The pronator is being released from the radial aspect of the radius in a subperiosteal manner. This subperiosteal dissection continues distally to release the origin of the mon flexor. 第五十頁，共一百四十頁。 After exposure of the volar aspect of the radius proximally and distally, two clamps can be placed on the ends of the bone in order to deliver them for cleaning. 第五十一頁，共一百四十頁。 FCR RADIAL ARTERY Each side of the fracture is be delivered in order to expose and clean the cortical edges. 第五十二頁，共一百四十頁。 These figures demonstrate delivery of the distal fragment and a curved curette being used to clean the cortical edge. No cleaning should be performed within the intramedullary canal,as this is healthy tissue and can be useful for the healing process. 第五十三頁，共一百四十頁。 Once the fractures are pletely cleaned along their cortical edges such that the fracture reduction can be visualized, the two clamps are used to reduce the fracture. If a butterfly fragment exists, it is necessary to fix this with a lag screw back to one of the fracture ends in order to realign the fracture. 第五十四頁，共一百四十頁。 In the current case, the fracture is a simple pattern and is reduced by delivering the bones jointly, ac
