A Novel Surgical Technique for Fixation of Recurrent Acromioclavicular Dislocations: AC Dog Bone Technique in Combination with Autogenous Semitendinosus Tendon Graft

Abstract

Various surgical techniques have been described for the fixation of acromioclavicular (AC) dislocations. However, recurrent dislocation is one of the main complications associated with the majority of these techniques. We report a case of postoperative AC joint redislocation. In order to overcome recurrent dislocation after revision surgery, a reconstruction of the conoid and trapezoid ligament with the use of a free tendon graft in combination with a FiberTape was provided within a novel surgical technique. After 12 months, the patient was very satisfied with the functional outcome. The patient achieved excellent results in the Constant (98 points), SPADI (0 points), and QuickDASH score (0 points). The described technique results in an anatomic reconstruction of the AC joint. The nonrigid nature of the intervention seems to restore the normal arthrokinematics by reconstructing the coracoclavicular ligaments with an autograft which is then protected by the AC Dog Bone artificial ligaments during the healing period. The arthroscopic approach to the AC joint with minimal exposure reduces the risks and complications of the intervention. This is the first case in literature that utilizes the artificial dog bone ligament securing the autograft in an anatomic AC reconstruction.

“…This one goes to work 2 weeks after operation. In contrast to the present study, reconstruction of the coracoclavicular ligament also includes an Endobutton system, adjustable-looplength suspensory fixation, suture anchors, an artificial tendon, absorbable sutures, and autogenous tendon transplantation [16,17]. Among them, the Endobutton system is the most widely used because it can provide a higher fixed strength.…”

“…The median CCD was 18 (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26) mm at the time of diagnosis, and it was 7.5 (6)(7)(8)(9)(10)(11)(12)(13)(14) mm after the operation 1 year later, representing a significant difference (t = −20.7 P< 0.001). The average VAS score preoperatively was 4.9 (3-7), and it improved to 0.55 (0-2), including the patient with subluxation, the difference was statistically significant (Wilcoxon test, median = −6, P < 0.001).…”

“…We propose that by separating the divergent clavicular limbs widely, the overall construct strength of the reconstruction will be increased, aiding stability in all planes, including the mediolateral plane. In addition, the smaller-than-usual drill holes 14,15 are likely to reduce risk of drill hole fracture.…”

“…Введение. По литературным данным вывихи акромиального конца ключицы (АКК) встречаются от 6,7% до 26,1% всех вывихов костей скелета, а переломы значительно реже [1,2,3]. Вывихи АКК наиболее часто встречаются у лиц молодого и трудоспособного возраста, от 20 до 50 лет [4,5], преимущественно у мужчин занимающихся физическим трудом и спортом [2].…”
