Arthroscopyassisted Reduction and Fixation of ValgusImpacted Femoral Neck Fractures with Joystick Te...

Valgus-impacted femoral neck fractures remain a challenging clinical entity. Associated deformities such as posterior tilt of femoral head, coxa valgus, and femoral neck shortening may produce femoroacetabular impingement, which adversely impacts on long-term joint function. Current reduction techniques face limitations: closed methods often fail to achieve satisfied reduction, open reductions require extensive soft-tissue dissection, and percutaneous joystick techniques are frequently fluoroscopy-dependent and imprecise. To address these problems, we describe a hip arthroscopy-assisted joystick reduction technique to achieve anatomical realignment. Under direct arthroscopic visualization, a Kirschner wire is precisely inserted into the femoral head to serve as joystick, allowing simultaneous correction of posterior tilt and valgus deformity. Real-time confirmation of reduction is followed by internal fixation using multiple cannulated screws. This technique provides direct visualization of both joystick placement and reduction maneuvers, minimizes fluoroscopy use, and allows for simultaneous joint decompression
