Acutrak screw fixation versus cast immobilisation for undisplaced scaphoid waist fractures

Fifty-three patients with less than 14 day-old, undisplaced fractures of the waist of the scaphoid were randomized to two groups. Twenty-eight patients were treated by immobilisation in a below elbow plaster cast for 10 weeks while 25 were treated by percutaneous insertion of an Acutrak standard screw. There were no statistically significant differences between the two treatment groups with regard to either the rate of union or the time to union. Patients who underwent surgery had a significantly better range of motion at 16 weeks but there were no significant differences for grip strength. Acute percutaneous internal fixation of undisplaced scaphoid waist fractures using the Acutrak screw allows early mobilisation without adverse effects on fracture healing.

Early CT for suspected occult scaphoid fractures

In this study, the use of computed tomography (CT) early in the management of suspected occult scaphoid fractures was evaluated. We retrospectively reviewed the notes and radiology of patients who had scaphoid CT scans over the preceding 3 years. Eighty-four patients that had CT scans within 14 days from injury were identified. Of the CT scans, 64% (n = 54) excluded a fracture and these patients were promptly mobilized. No patients returned with any complications from this management. Overall, 36% of CT scans were abnormal (n = 30), 7% revealed occult scaphoid fractures, 18% revealed occult carpal fractures of the triquetrum, capitate, and lunate, respectively, and 5% revealed distal radius fractures. All patients diagnosed with fractures were successfully managed with plaster immobilization and there was one case of complex regional pain syndrome. Early CT alters therapeutic decision making in suspected occult fractures preventing unnecessary immobilization in a working population without increase in cost.     

Interfragmentary compression across a simulated scaphoid fracture--analysis of 3 screws

PURPOSE: To measure the interfragmentary compression generated across a simulated fracture in cadaveric scaphoids by 3 different headless compression screws. METHODS: A transverse osteotomy was made through the waist of each scaphoid and a load cell to measure compression was interposed between the fragments, which were then fixed internally retrograde with either an Acutrak Standard (n = 10), Acutrak Mini (n = 12), or Bold (n = 10) screw. The surgeon was blinded to the measured compression, which was recorded during screw insertion and for the following 5 minutes. As a measure of scaphoid bone quality the modulus of elasticity of the trabecular bone of each specimen was then calculated from uniaxial compression tests. RESULTS: The mean interfragmentary compression generated by the Acutrak Standard screw was significantly greater and more consistent than the Bold screw or the Acutrak Mini screw. The compression achieved by the Acutrak Standard screw was also more consistent than that obtained by either the Bold or the Acutrak Mini screws as reflected by the lower standard deviation. The mean modulus of elasticity of the scaphoid trabecular bone was similar for each screw group. CONCLUSIONS: The interfragmentary compression generated by the Acutrak Standard screw was significantly greater and more consistent than that generated by either the Bold or Acutrak Mini screws. The compression generated by the Acutrak Standard and Mini screws was significantly better sustained over time than that generated by the Bold screw; however, these differences were small and may not be clinically important. The optimal compression required to promote scaphoid fracture union remains unknown and clinical trials are needed to further evaluate the outcome from using these devices.

Medium-term results of trapezio-lunate external fixation for scaphoid fractures

We treated 36 scaphoid fractures in 34 patients with trapezio-lunate external fixation. According to the Herbert and Fisher classification, there were 16 type B1, 14 type B2, four type B3 and two type B4 fractures. Trapezial and lunate pins broke in three patients and these were rated as failures. The remaining 33 fractures were followed-up for 3 years and all had excellent outcomes, without signs of arthritis, avascularity or instability.
