Stabilization of the Dislocated Acromioclavicular Joint with Ligament Suture and Balser Hook Plate

Biomechanical Evaluation of 3 Stabilization Methods on Acromioclavicular Joint Dislocations

“…The HP is still one of the most commonly used implants for acute AC dislocations with good clinical and biomechanical results. 4,9,12,14,30 McConnell et al, 20 Both clavicles fractured around the medial screw of the HP. In our opinion, the fractures were caused by potentially associated osteoporosis.…”

“…The HP is still one of the most commonly used implants for acute AC dislocations with good clinical and biomechanical results. 4,9,12,14,30 McConnell et al, 20 The 2 postoperative failures in the HP group might have been related to inferior bone density and the small diameter of the clavicles. The BMD values of the lateral clavicles of these 2 joints were among the lowest of all specimens (197.0 and 212.6 mg/cm 3 ; the mean value of all specimens was 242.4 6 37.6 mg/cm 3 ).…”

“…An advantage of the HP is the relatively easy implantation procedure and early postoperative mobilization. However, known disadvantages of the HP are recurrent dislocations 12 and skin/wound complications, 30 and Folwaczny et al 9 noted only a 63.2% patient satisfaction rate postoperatively. The main disadvantage is the necessity of implant removal.…”

“…16 The hook plate is a commonly used stabilization device for functional AC joint restoration and reduction maintenance. 4,8,9,12,14,30 Recently, less invasive implant systems such as the Flipptack (Karl Storz, Tuttlingen, Germany) and TightRope (Arthrex GmbH, Munich, Germany) have been introduced, aspiring toward a first-choice implant. 32,33 The use of 2 bone anchors also offers an attractive alternative in minimally invasive AC joint stabilization.…”
