Volar approach percutaneous minimally invasive treatment for fresh scaphoid waist fracture with headless hollow compression screw

Objective To explore the operation skills and clinical efficacy of volar approach percutaneous minimally invasive treatment for fresh scaphoid waist fracture with headless hollow compression screw. Methods From May 2015 to May 2018, 14 cases of fresh scaphoid waist fractures were treated with percutaneous headless hollow compression screws through the volar approach. There were 3 cases of Herbert A2 type, 2 cases of B1 type and 9 cases of B2 type. They were undisplaced or slightly displaced (≤1 mm) fractures. The patients were followed up after operation to evaluate the clinical efficacy. Results All the 14 cases were successfully completed with intraoperative bleeding of 5 to 20 ml with an average of 12 ml. The operation time ranged from 40 to 75 min with an average of 55 min. The fracture reduction and screw position were correct. 13 patients were followed up and 1 patient was lost. The follow-up time ranged from 6 to 18 months, with an average of 12 months. All the fractures healed well without loosening of internal fixator. According to the Mayo wrist function score, the results were rated as excellent in 10 cases, good in 2 cases and fair in 1 case. Conclusion The volar approach percutaneous minimally invasive treatment for fresh scaphoid waist fracture with headless hollow compression screw has the advantages of small injury, high rate of fracture healing and definite curative effect.
