title: [Application of absorbable screw in treatment of scaphoid fracture by retrograde internal fixation].
abstract: OBJECTIVE
  To evaluate the surgical effects of treatment of scaphoid fracture with retrograde internal fixation using absorbable screw.
  
  
  METHODS
  From December 2001 to December 2007, 18 cases of scaphoid fracture were treated with absorbable screw by retrograde internal fixation. There were 12 males and 6 females with an average age of 26 years ranging from 17 to 40 years. Ten cases were medium fractures of scaphoid and 8 cases were proximal fraxtures.
  
  
  RESULTS
  All patients were followed-up for from 12 to 36 months (means 25 months). Among them, 17 cases were union and 1 case was nonunion. The mean time of union was 13 weeks. The mean range of motion of wrist was about 90% and mean scratch strength of wrist was about 95% to fine lateral. There were no pain in 14 cases, and slight pain in 3, medial pain in 1 casea of ununion. According to Cooney's clinical evaluation system, the score was increased from (68.2 +/- 1.5) before operation to (88.7 +/- 1.2) after operation, the postoperative score was higher than preoperative remarkable; 9 patients were fine, 8 were good and 1 was bad.
  
  
  CONCLUSIONS
  This technology had some advantage such as simple surgery, decreasing demonstrate rest blood circulation, stable fixation, reducing bone healing time and increasing healing time. It is an effective way to treat scaphoid fracture.
