The aim of this study was to compare the accuracy and reliability of percutaneous fixation of minimally displaced scaphoid fractures using a customized three-dimensional (3-D)-printed guide with a conventional freehand method. A prospective cohort of ten patients underwent scaphoid fixation with the aid of a customized 3-D-printed guide. The final screw position, total surgery time (minutes) and fluoroscopy time (seconds) was compared with a retrospective cohort of ten patients who underwent fixation with a conventional technique. There were no differences in final screw position between both methods. The patients in which the 3-D guide was used had a surgery time reduction of 43% and a fluoroscopy time reduction of 52% compared with the control freehand group. The use of a customized 3-D-printed guide permits a fixation that is as accurate as the standard freehand technique, with reduction in surgical time and intraoperative radiation exposure. Level of evidence: III

Partial trapeziectomy is performed to decrease the risk for first ray collapse. However, the incidence of scaphotrapezoidal (ST) joint osteoarthritis (OA) in the presence of advanced trapeziometacarpal joint OA is around 40%. The purposes of this study were to analyze the progression of the ST joint after partial trapeziectomy and to establish the potential link between radiographic findings and patient outcomes. Methods: We reviewed a series of 22 patients (26 thumbs) with base of the thumb OA who underwent partial trapeziectomy and interposition arthroplasty. Standardized radiographs of the ST joint were classified by 2 independent observers. Measured outcomes were pain, mobility (degrees of abduction, Kapandji score, and anteversion [in centimeters]), force (in kilograms]) and the short version of the Disabilities of the Arm, Shoulder, and Hand questionnaire score. Results: Median follow-up was 8 years. The modified EatoneGlickel scale was used to rate the degree of ST joint arthritis: 2 thumbs were classified as grade 1, 11 as grade 2, 12 as grade 3, and 1 as grade 4. No parameters analyzed demonstrated a statistically significant correlation between patients' outcomes and joint radiographic arthritis. Conclusions: Our study cannot demonstrate that the radiographic presence of ST arthritis correlates with the patient's main symptoms after partial trapeziectomy. Type of study/level of evidence: Therapeutic IV.
