Abstract
Scaphoid fracture accounts for 60% of carpal fractures. The mechanism of fracture occurs after a fall with the hand extended, in pronation and radial or ulnar deviation in addition to the importance, they gain for their frequency; clinically, their problem lies in the high possibility of non-consolidation, due to the type of vascularization that it has, fractures located mainly in the waist and in the proximal pole are a high-risk factor. Most of the up-to-date papers available confirm a positive outcome of the use of focused extracorporeal shock wave therapy (ESWT-F) in pseudarthrosis. According to the literature, the success rate is between 50% and 91%. Complications when ESWT-F are performed by qualified personnel and following the standards established by international scientific organizations, are limited to petechiae and local hematomas having as a requirement, to be performed by trained personnel. This manuscript will discuss a series of cases treated in a certified center for the application of Focal Shock Waves between 2018 and 2021 to patients with scaphoid fracture with a diagnosis of Fracture Consolidation Delay and pseudarthrosis of scaphoids, which subjected to treatment with high-intensity focal shock waves under ultrasound guidance. We analyzed six male patients with an average age of 31.3 years who were treated with ESWT-F. About 33.3% were taken to osteosynthesis as initial management without achieving satisfactory bone consolidation; hence, ESWT-F was performed. About 0% complications were reported, bone consolidation occurred in 100% of patients on average of 6 weeks from the last session of ESWT-F. The results were clinically evaluated, where 100% of patients manifested a decrease in pain by an average of 75% at 2 weeks of the last session of ESWT-F and 100% at 12 weeks. In the imaging evaluation, the six patients (100%) showed signs of bone consolidation in the complete radiological assessment at 12 weeks and the Disabilities of the Arm, Shoulder, and Hand scale applied revealed improvement in their functional capacity.
