Arthroscopically assisted use of injectable bone graft substitutes for management of scaphoid nonunions
1Department of Orthopaedic Surgery, Taoyuan Armed Forces General Hospital, Taoyuan County, Taiwan.
Purpose:
The purpose of this study was to analyze the clinical follow-up results (minimum, 2 years) in patients with nonunions of the scaphoid with minimal sclerosis treated with arthroscopically assisted percutaneous internal fixation augmented by injection of a bone graft substitute.
Methods:
From January 2006 through November 2007, a consecutive series of 15 patients with fibrous union or nonunion of a carpal scaphoid fracture with minimal sclerosis or resorption at the nonunion site were treated with arthroscopically assisted percutaneous internal fixation combined with the use of injectable bone graft substitute. Preoperative and postoperative evaluations included measurement of clinical (grip strength and range of motion), radiographic, and functional (Mayo Modified Wrist Score) parameters, as well as satisfaction. The sample included 13 men and 2 women with a mean age of 31 years (range, 20 to 45 years). We recorded union and return to activity and analyzed data with regular clinical follow-up at a mean of 33 months (range, 24 to 46 months).
Results:
We confirmed union in 14 of 15 patients (93%) at a mean of 15.4 weeks according to clinical examinations and standard radiography. For the Mayo Modified Wrist Score, there were 10 excellent and 4 good results. A total of 14 of 15 patients (93%) returned to work or sports activities at their preinjury level.
Conclusions:
Arthroscopically assisted treatment with percutaneous internal fixation with injectable bone graft substitute is a reliable and minimally invasive method to achieve union and scaphoid healing.
Level Of Evidence:
Level IV, therapeutic case series.
