In addition drilling holes or fixation through coracoid can be fraught with complications due to adjacent anatomy of coracoid. Anteroposterior, lateral, and axial views are standard views taken for the shoulder; however, a Zanca view [ 12 ] is the most accurate view to look at the AC joint. Norrell H, Lyewellyn RC. Some lateral sleeping pain on same side is expected in the early days but full functional restoration is possible. Treatment with Dacron ligament.
An indirect suture shuttle usually Ethilon 1 is passed under the coracoid with the help of a Satinsky forceps from medial to lateral. After 6 weeks all restrictions are discarded. The anterior-posterior displacement of AC joint also tends to cause more symptoms, which may be unaddressed, by merely restoring the superior inferior stability with CC ligament reconstruction. Bipolar clavicular dislocation treated surgically. Tossy et al [ 5 ] and Allman [ 2 ] initially described the classification of acromioclavicular injuries as types I, II, and III in the s.
A prospective controlled randomized study. In addition drilling holes or fixation through coracoid can be fraught with complications due to adjacent anatomy of coracoid.
Acromioclavicular joint dislocations
Early fixation techniques described were using K-wires, Steinman pins and cerclage wires. A synthetic graft or screw is unlikely to sustain cyclic loading forever. The anterior-posterior displacement of AC joint also tends to cause more symptoms, which may be unaddressed, by merely restoring the superior inferior stability with CC ligament reconstruction.
Suture anchor in coracoid. This is preventable by ghesis an AC ligament reconstruction to the surgery.
Acromioclavicular joint dislocations
Even if native CC ligament were to heal, it would do so in a lengthened position. Eaton R, Serletti J. A major injury will lead to further transmission of force and disruption of the deltoid and trapezius muscles, as the lateral end of clavicle herniates through it [ 4 ]. Even among surgeons inclined to operate AC joint dislocations there is no unanimity on which surgical technique. A biomechanical evaluation of an anatomical coracoclavicular ligament reconstruction.
Abstract Acromioclavicular AC dislocation is a common injury especially among sportsmen. This procedure was initially described inutilized the Coraco-Acromial CA ligament to substitute the torn CC ligament; this procedure involved the release of the Coraco-Acromial ligament from the acromion, resection of the distal end of the clavicle, and transfer of the CA ligament to the lateral end of the clavicle, more closely replicating the CC jonit.
Coracoid fracture with recurrent AC joint separation after tightrope repair of AC joint acromioclavicukar.
The coracoclavicular CC ligaments prevent superior-inferior displacement of the clavicle. Stam L, Dawson I.
Bosworth screw Stabilization of AC joint with a screw between clavicle and coracoid. Lee et al [ 2324 ] compared tendon grafts with suture materials and Weaver Dunn grafts in acromioclaviculxr cadaveric model. Complications Across the board, each technique has its typical fault lines.
The most common complaint in the late setting is a nagging medial scapular pain. Repair of acromioclavicular separation using a Dacron prosthesis graft.
There was noticeable superior migration of the clavicle in 4 of the 43 patients but none of them were clinically symptomatic. Biomechanical studies in cadaveric models showed that the use of a Coraco-Clavicular screw, reduced joint motion, and significantly increased joint contact pressures, which could have implications for early joint degeneration when this technique is used [ 15 ].
Failure could present as Lateral end clavicle osteolysis, hardware failure, or even fracture of coracoid or clavicle [ 16 — 19 ]. Acromioclavicular AC joint injuries are not uncommon and occur across different age groups.
Under general anesthesia, with the patient in a beach chair position, the shoulder and arm is acrimioclavicular free.
Anatomy The AC joint is a diarthrodial joint formed by the distal clavicle and the medial facet of the acromion. The anatomic coracoclavicular ligament reconstruction: Procedures that involve blind drilling of coracoid without dissection may have a high chance of injury to the plexus.
Norrell H, Lyewellyn RC. A cadaveric study examining acromioclavicular joint congruity after different methods of coracoclavicular loop repair.
Acromioclavicular joint injuries in sport: Most common is type III.
The AC joint is a diarthrodial joint formed by the distal clavicle and the medial facet of the acromion. Treatment of acromioclavicular joint separation: This can be facilitated by the surgeon, using finger dissection, to burrow a tunnel underneath the deltoid flap.
