1 Arthroscopically Assisted Acromioclavicular and Coracoclavicular Ligament Reconstruction for Chronic Acromioclavicular Joint Instability  Frank Martetschläger, M.D., Mark Tauber, M.D., Peter Habermeyer, M.D., Nael Hawi, M.D.  Arthroscopy Techniques  Volume 5, Issue 6, Pages e1239-e1246 (December 2016) DOI: /j.eats Copyright © 2016 Arthroscopy Association of North America Terms and Conditions

2 Fig 1 Beach chair position, right shoulder, arthroscopic view from the posterior portal. An anteroinferolateral working portal is established within the rotator interval, and a flexible passport cannula (PC) (Arthrex, 4 cm) is inserted to facilitate suture and graft management.

3 Fig 2 Beach chair position, right shoulder, arthroscopic view from the posterior portal. A high trans-supraspinatus portal is established directly behind the long head of the biceps. The arthroscope is then switched into this portal for better visualization of the subcoracoid space. Care must be taken not to damage the rotator cable. (HH, humeral head; KN, knife; SSP, supraspinatus tendon.) Arthroscopy Techniques 2016 5, e1239-e1246DOI: ( /j.eats ) Copyright © 2016 Arthroscopy Association of North America Terms and Conditions

4 Fig 3 Beach chair position, right shoulder, arthroscopic view from the trans-supraspinatus portal. Under direct visualization the undersurface of the coracoid is skeletonized (undersurface of coracoid base [CB]) using a radiofrequency device (RD) (OPES, Arthex) through the anteroinferolateral portal.

5 Fig 4 Beach chair position, right shoulder, arthroscopic view from the trans-supraspinatus portal. A drill guide is used to place a K-wire (KW) through the distal clavicle at the level between the conoid and trapezoid ligament insertion and through the central portion of the coracoid base (CB) using an aiming device (AD).

6 Fig 5 Shoulder model, right shoulder, after the confirmation of correct positioning through fluoroscopy. The K-wire is overdrilled using a cannulated 4-mm drill (CD) and the K-wire is removed.

7 Fig 6 Beach chair position, right shoulder, arthroscopic view from the trans-supraspinatus portal. A suture passing device (PD) is inserted through the cannulated drill (CD) and removed through the anteroinferolateral portal using a conventional grasper. (CB, coracoid base.)

8 Fig 7 Shoulder model, right shoulder; the strands of the suture tape (ST) (FiberTape, Arthrex) are inserted into a cortical fixation button (DogBone, Arthrex) outside the anteroinferolateral portal. The 2 strands of the suture tape and the Ethibond sutures of one graft end (GR) are threaded inside the passing device (PD).

9 Fig 8 Beach chair position, right shoulder, arthroscopic view from the trans-supraspinatus portal; using a passing suture, strands of a suture tape (ST) (FiberTape, Arthrex) along with the Ethibond sutures of one end of the graft are pulled through the bone tunnel from inferior to superior through the anteroinferolateral portal. (CB, coracoid base.) Arthroscopy Techniques 2016 5, e1239-e1246DOI: ( /j.eats ) Copyright © 2016 Arthroscopy Association of North America Terms and Conditions

10 Fig 9 Beach chair position, right shoulder, arthroscopic view from the trans-supraspinatus portal; the cortical fixation button (DogBone [DB], Arthrex) is positioned at the undersurface of the coracoid process (CB) and above the graft by pulling on the suture tapes.

11 Fig 10 Shoulder model, right shoulder, view from the anterosuperior portal; the free end of the graft (GR) is pulled superiorly in front of the clavicle using a grasper (e.g., FiberTape Retriever, Arthrex). (DB, DogBone; ST, suture tape.) Arthroscopy Techniques 2016 5, e1239-e1246DOI: ( /j.eats ) Copyright © 2016 Arthroscopy Association of North America Terms and Conditions

12 Fig 11 Shoulder model, right shoulder, view from above; the free end of the graft (GR) is pulled superiorly in front of the clavicle using a grasper (e.g., FiberTape Retriever, Arthrex). (ST, suture tape.) Arthroscopy Techniques 2016 5, e1239-e1246DOI: ( /j.eats ) Copyright © 2016 Arthroscopy Association of North America Terms and Conditions

13 Fig 12 Shoulder model, right shoulder, view from above; after the acromioclavicular joint is reduced, the 2 strands of the suture tape (ST) are knotted over a second cortical fixation button (DB) on the distal clavicle. After correct joint reduction is confirmed by fluoroscopy, the free ends of the graft (GR) are also knotted together over the clavicle leaving one long end.

14 Fig 13 Shoulder model, right shoulder, view from above; two 4-mm drill holes are placed through the acromion in the craniocaudal direction, approximately 1 cm lateral to the AC joint line. (AC, acromioclavicular; DB, DogBone; GR, graft; KW, K-wire; ST, suture tape.)

20 Fig 19 Shoulder model, right shoulder, view from above; the ends of the suture tapes (ST) and the end of the graft (GR) are knotted together, thus creating a trapezoidal acromioclavicular graft augmentation. The free ends are cut. Arthroscopy Techniques 2016 5, e1239-e1246DOI: ( /j.eats ) Copyright © 2016 Arthroscopy Association of North America Terms and Conditions

21 Fig 20 Shoulder model, right shoulder, view from the anterosuperior portal; the ends of the suture tapes (ST) and the end of the graft (GR) are knotted together, thus creating a trapezoidal acromioclavicular graft augmentation.

25 Fig 24 Shoulder model, right shoulder, view from inferior, showing looping one strand of the graft (GR) in front of the clavicle and the other end through the coracoid base and distal clavicle. After knotting both ends above the clavicle, the longer strand is used to create the AC augmentation. (AC, acromioclavicular; DB, DogBone.)
