Current concepts in the diagnosis and management of acromioclavicular dislocations

Not all complete dislocations of the acromioclavicular joint should be treated by one method alone. A classification of acromioclavicular dislocation is presented and is based upon the pathology of the injury. Grade I sprain results from a mild force that causes tearing of only a few fibers of the acromioclavicular joint. Grade II sprains are caused by a moderate force with a rupture of the capsule and acromioclavicular ligament. Grade III sprains result from a severe force that ruptures both the acromioclavicular and coracoclavicular ligaments and causes a dislocation of the joint. Grade IV dislocation may be associated with an avulsion fracture of the coracoclavicular ligament from the inferior lateral clavicle, severe tearing or other injury to the soft-tissue envelope about the lateral clavicle, or a buttonhole injury of the lateral clavicle. Grade V dislocation refers to a posterior displacement of the lateral clavicle from any cause, while Grade VI relates to an inferior lateral clavicle displacement. Grades I, II, and most Grade III injuries can be treated conservatively. The indications for open treatment of Grade III injuries are reviewed. It is recommended that Grade IV and most Grade V and VI dislocations be managed with open methods.

Arthroscopic Stabilization of Neer Type 2 Fracture of the Distal Part of the Clavicle

With regard to the anatomic basis of Neer type 2 fractures of the distal part of the clavicle, a clavicle fracture is associated with a coracoclavicular conoid ligament disruption. We describe an arthroscopic-assisted surgical procedure to stabilize the fracture and reconstruct the ligament. Surgery is performed with the patient in the beach-chair position. Through a 2-cm incision perpendicular to the direction of the fracture, we perform suturing around the fracture. During the arthroscopic procedure, the coracoid process is exposed by opening the rotator interval and the medial part of the capsule. The knee of the coracoid process should be exposed via an anterolateral portal for the arthroscope. Then, by use of an acromioclavicular joint stabilization device from Arthrex (Naples, FL), a hole is placed through the knee of the coracoid process. FiberTape suture (Arthrex) is passed around the clavicle and through the knee of the coracoid process. The intra-articular sutures are pulled out through the upper incision on top of the clavicle. Tightening of the 2 knots is performed at the same time. This arthroscopic-assisted surgery allows for total recovery of shoulder function, without the inconvenience of device migration or acromioclavicular joint lesions reported with other procedures.

Arthroscopic Coracoclavicular Ligament Reconstruction Using Biologic and Suture Fixation

Presented in this report is a modified arthroscopic approach to acromioclavicular joint reconstruction via suture and allograft fixation. An arthroscopic approach is used to expose the base of the coracoid by use of electrocautery. After an open distal clavicle excision is performed, clavicular and coracoid tunnels are created under arthroscopic visualization as previously described by Wolf and Pennington. The myotendinous end of a semitendinosus allograft is sutured to a Spider plate (Kinetikos Medical, San Diego, CA). The tendinous end of the graft is prepared with a running baseball stitch. A Nitinol wire with a loop end (Arthrex, Naples, FL) is used to pass 2 free FiberTape sutures (Arthrex) and the leading sutures from the tendinous end of the graft through the clavicular and coracoid tunnels, exiting out the anterior portal. One of the FiberTape sutures is retrieved with a grasper and passed over the anterior aspect of the distal clavicle. The second FiberTape suture and the allograft are passed over the distal end of the resected clavicle. While the acromioclavicular joint is held reduced, the FiberTape sutures are tied to the plate and the allograft is tensioned medially until the plate is embedded against the superior surface of the clavicle. The tendinous end of the graft is secured to the superior surface of the clavicle with a Bio-tenodesis screw (Arthrex) medial to the clavicular tunnel.     

Acromioclavicular Joint Reconstruction Using Peroneus Brevis Tendon Allograft

We describe the use of a double-strand peroneus brevis allograft to reconstruct the coracoclavicular and acromioclavicular (AC) joint ligaments. Through sharp dissection, the distal clavicle, the AC joint, and the torn superior AC and coracoacromial ligaments are identified. The coracoid process and injured coracoclavicular ligaments are identified with blunt dissection. A 1-cm segment of the lateral clavicle is resected. Vertical and connecting horizontal tunnels are created (4.5 mm) in the lateral clavicle and in the medial acromion process. The 5.5- to 6.0-mm-diameter allograft is looped around the coracoid process, and both strands are passed through the vertical clavicle tunnel with a nitinol wire loop. One strand passes through the vertical clavicle tunnel, and the other strand passes through the horizontal tunnel, exiting through the lateral end. The allograft strand passed through the vertical clavicle tunnel is then passed inferiorly through the superior vertical acromion tunnel, and the strand passed completely through the horizontal clavicle tunnel is passed laterally through the medial horizontal acromion tunnel. After both strands exit inferiorly through the vertical acromion tunnel, they are tensioned and sutured with AC joint reduction. Soft tissue closure uses No. 0 and No. 2-0 absorbable sutures with No. 3-0 nylon sutures at the skin.     

喙锁韧带重建的解剖放射学研究

目的测量不同透视体位下喙锁韧带骨道走行的放射学参数，为临床喙锁韧带重建提供解剖学依据。 方法取22具防腐处理的成人肩关节标本，解剖测量喙锁韧带两部分（斜方韧带，锥状韧带）的走行方向、止点宽度及透视体位下成角。 结果斜方韧带锁骨侧足印宽度（26.2±1.2） mm，喙突侧（22.7±1.6）mm。锥状韧带锁骨侧足印宽度（24.6±1.4）mm，喙突侧（19.2±1.6）mm。影像学测量韧带的插入角度：肩胛骨正位与锥状韧带与锁骨长轴成角（81±4）°，斜方韧带成角（67±7）°。侧位成角：斜方韧带（83±3）°，锥状韧带（70±6）°。与外科标志的毗邻关系：斜方韧带与锥状韧带足印区长轴中心点在锁骨间距（21.9±4.8）mm，在喙突侧间距（15.7±1.6）mm。 结论锥状韧带及斜方韧带止点足印宽度较为恒定，斜方韧带插入角度有变异度较大，锥状韧带较为恒定。两韧带在锁骨及喙突上间距较小。在进行肩锁关节解剖重建时，可参照其解剖学特点。     

Coracoclavicular Ligament Reconstruction Using a Semitendinosus Graft for Failed Acromioclavicular Separation Surgery

Although acromioclavicular joint separations are fairly common, the occurrence of high-grade acromioclavicular separations that require surgery is low. Various modifications of the Weaver-Dunn procedure have been popular and fairly successful methods to treat severe acromioclavicular separations, despite the fact that reconstructions have been done a number of ways. We report on the results of a technique for salvaging failed modified Weaver-Dunn reconstructions using a semitendinosus graft through bone tunnels in the distal clavicle and coracoid to reconstruct the coracoclavicular ligament.     

Biomechanical comparison of reconstruction techniques for disruption of the acromioclavicular and coracoclavicular ligaments

Injuries to the acromioclavicular joint are common. For selected injuries, operative reconstruction is recommended. The purpose of the current study was to compare three reconstruction procedures: (1) nine strands of woven polydioxanonsulphate (PDS II) suture passed through the clavicle and around the coracoid; (2) procedure No. 1 with 50% of the coracoacromioclavicular ligament placed through 2 clavicular drill holes; (3) No. 5 Merselene tape passed through 2 drill holes in the clavicle and acromion, with 50% of the coracoacromial ligament transferred to the clavicle. Fourteen fresh frozen human shoulders were tested using a 6 degree-of-freedom testing device. The intact shoulder showed significantly less displacement than any of the reconstructions. Merselene tape plus ligament showed the largest displacement, and PDS II braid plus ligament showed the least displacement. None of the procedures reconstituted acromioclavicular joint stiffness to intact state levels, though improved acromioclavicular joint stiffness was noted with a PDS braid plus ligament.     

锁骨中段骨折合并同侧肩锁关节脱位：诊断要点分析研究

目的探讨锁骨中段骨折合并同侧肩锁关节脱位的诊断要点,为临床早期诊断该类损伤提供参考。 方法通过分析国内外文献报道的病例,并回顾性分析本科室随访病例,从年龄、性别、受伤原因、锁骨中段骨折及肩锁关节脱位分型等方面进行分析。 结果共检索到19篇锁骨中段骨折伴同侧肩锁关节脱位的英文病例报道、7篇中文文献病例报道,其中有清晰术前X线片的病例共22例。同时,回顾性分析了本院临床随访的2例该类病例,因此,最终有24例病例纳入分析研究。其中,男16例、女8例;最小年龄为19岁,最大年龄为65岁,平均年龄为37岁。大部分由高能量损伤所致（21/24, 87.5%）。锁骨骨折类型分型：19例（19/24,79.2%）属于A型骨折,5例（5/24,20.8%）属于B型骨折;肩锁关节脱位分型：IV型12例（50.0%）、III型6例（25.0%）,VI型4例（16.7%）,V型2例（8.3%）;9例（9/24,37.5%）患者有合并损伤。 结论对于高能量损伤导致的相对简单类型的锁骨中段骨折,需高度怀疑有无同侧肩锁关节脱位,诊断要点如下：（1）详细询问受伤原因,了解受伤机制;（2）对所有锁骨中段骨折病例,需观察肩锁关节处有无肿胀、皮下青紫,并对肩锁关节及喙突处进行压痛体格检查,如有压痛,则高度怀疑肩锁关节损伤;（3）需仔细观察术前X线肩锁间隙及喙锁间隙变化,如锁骨中段骨折为相对简单类型,且为高能量损伤者,需高度怀疑,建议加拍对照位片及患侧肩关节CT检查;（4）术中锁骨中段骨折固定后,常规透视同侧肩锁关节。     

The operative treatment of fresh ruptures of the acromioclavicular joint (Tossy III)

We give a preliminary report of ten patients with fresh dislocations of the acromioclavicular joint (Tossy III). All ten were operated with suture of the torn ligaments and indirect fixation of the acromioclavicular joint with a monocerclage wire passed around the coracoid process and the clavicle. Removal of metal was done 8 weeks later. None of the wires broke, and there were no problems with wound healing. Control X-rays under stress revealed stable acromioclavicular joints in all cases.
