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.     

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。     

Acromioclavicular joint reconstruction using the Nottingham Surgilig: a preliminary report

Eleven patients with a chronic acromio-clavicular joint disruption underwent acromio-clavicular joint stabilisation using the Nottingham Surgilig and were followed up clinically and radiologically for an average of 24 months post operation. The mean post-operative Constant score was 83.1, the Imatani score was 81.2 and the Walsh score was 14.1. Eighty-two per cent of patients were satisfied with the operation. There was one case of rupture through the central portion of the Surgilig, and following laboratory analysis, the ligament has been modified since. In 4 patients there was evidence of loosening of the screw but only one complained of this being a problem. This short-term outcome analysis of the Nottingham Surgilig is the first such report outside the Nottingham unit where the prosthesis was originally developed. Our results are encouraging and justify further use and evaluation of this relatively new technique.     

带袢钢板重建喙锁韧带与锁骨钩钢板治疗 锁骨远端骨折的病例对照研究

目的：探讨带袢钢板加爱惜帮缝线双束重建喙锁韧带和锁骨钩钢板治疗NeerⅡ型锁骨远端骨折的疗效差异。方法：2008年11月至2009年12月,采用带袢钢板加爱惜帮缝线双束重建喙锁韧带（A组8例）和锁骨钩钢板（B组10例）治疗18例锁骨远端骨折患者,其中男10例,女8例,年龄28～65岁,平均38岁。所有损伤均为新鲜损伤,X线表现为NeerⅡ型锁骨远端骨折,损伤至手术时间为2～5d,平均2.8d。所有患者受伤前肩关节活动均正常。术后第1、2、3个月对患肩功能用Constant Murley评分系统进行评分。结果：两组患者切口均Ⅰ期愈合,无感染发生,无臂丛神经损伤。X线提示,所有骨折在术后3个月时有连续骨小梁通过,证实骨折愈合。所有患者均获得随访,时间3～8个月,平均5.7个月。术后第1、2、3个月,A组Constant Murley评分分值分别为：（91.4±6.7）、（97.5±2.6）、（98.3±2.0）分;B组分别为：（70.1±5.1）、（89.0±7.6）、（94.2±4.6）分。在术后1、2、3个月,A组的肩关节评分均高于B组,差异具有统计学意义（P〈0.05）。结论：带袢钢板加爱惜帮缝线双束重建喙锁韧带治疗NeerⅡ型锁骨远端骨折,由于不影响肩锁关节,患者可以获得更好的肩关节功能,虽然这一固定方式是非坚强固定,但是所有骨折均愈合。这一技术的应用有赖于完整和坚强的喙突,在小喙突和骨质疏松的患者中可能不适用。

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.     

Acute acromioclavicular dislocations treated by fixation of the joint and ligament repair or reconstruction

We reviewed 55 patients, median age 34 years, who had had acute complete acromioclavicular dislocation treated by transient acromioclavicular fixation with a Knowles pin and ligament repair by suturing or reconstruction of the superior acromioclavicular ligament with transfer of the coracoid end of the coracoacromial ligament onto the clavicle. At followup examination 50 patients showed at least a satisfactory result. Five cases, two of which had had subsequent resection of the distal end of the clavicle, were classified as poor, mainly because of pain, even though the functional result was good in three. Reconstruction of the superior acromioclavicular ligament, although it improved the anatomic result, was shown to be of no advantage and may even have caused discomfort. The numerous radiological findings of residual subluxation or dislocation, deformity of the distal end of the clavicle, soft tissue calcification and osteoarthritis or pathological physical findings did not correlate significantly with the clinical outcomes. In general this operation gave results comparable with those achieved by other operative methods. It is useful if surgery is preferred to conservative treatment.     

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.     

Minimally Invasive Coracoclavicular Ligament Augmentation With a Flip Button/Polydioxanone Repair for Treatment of Total Acromioclavicular Joint Dislocation

Treatment of complete acromioclavicular joint disruption remains controversial and ranges from rehabilitation to extensive surgical reconstruction. However, high-grade injuries (type IV, V, and VI) are typically treated surgically. Most reconstruction techniques addressing these injuries selectively focus on coracoclavicular ligament augmentation because it has been shown to be the primary stabilizer of the acromioclavicular joint. The conventional coracoclavicular polydioxanone (PDS) loop, which is widely performed, has been detected to have some pivotal disadvantages, including anterior subluxation of the clavicle, extensive preparation of the coracoid, and bony avulsion of the clavicle as a result of rotational clavicle movement. Therefore we present an augmentation technique that reduces these complications by replicating the orientation of the native coracoclavicular ligament complex and providing a minimally invasive subcoracoid and clavicular fixation of a double PDS loop by use of 2 flip buttons, typically used for extracortical anterior cruciate ligament graft fixation. The key step of the procedure includes the anatomic, secure, and stable placement of the double PDS cerclage under the coracoid base transferring a flip button through a coracoid bone tunnel. Our clinical experience shows that the presented technique is easy to perform and has a comparable invasiveness to recently presented arthroscopic techniques.

Coracoid fracture combined with distal clavicle fracture without coracoclavicular ligament rupture: A case report

Distal clavicle fracture accompanied by coracoid process one is a rare injury. Surgical and/or conservative treatments are proposed. We report the case of a 49-year-old woman presenting a distal clavicle fracture associated with a coracoid process one due to a fall on the left shoulder. Both injuries are treated surgically. Per operatively, and through an anterior “strap” approach, the coracoclavicular ligament was seen intact. The distal clavicle fracture was fixed with K-wires and cerclage and the coracoid process was secured by a screw. Active-assisted rehabilitation of the shoulder was initiated 3 weeks after surgery. At the last follow-up of twelve months, the patient had painless full shoulder functions and X-rays show bony union. Early recovery to normal life is possible with surgical treatment in patients with distal clavicle fracture combined with coracoid fracture.     

Radiological study of the Asian coracoid process and clavicle: Implications for coracoclavicular ligament reconstruction

Purpose:Iatrogenic coracoid and clavicle fracture is a known complication of drilling bone tunnels during anatomic coracoclavicular ligament reconstruction(ACCR).This study aims to measure the dimensions of coracoid process and clavicle in an Asian population to evaluate the suitability of drilling coracoid and clavicle tunnels for ACCR in Asians.Methods:Width measurements of 196 coracoids and 189 clavicles were obtained after reviewing all computed tomography(CT)scans of the shoulder performed over a 6 years period.Coracoid measurements were made on the CT slice which showed the maximum cross sectional width of the coracoid base.Medial to lateral measurements of the coracoid width were taken on an axial view,4 mm above the identified junction of the coracoid base and glenoid base.Antero-posterior clavicle width was measured through a point directly above the midpoint of the coracoid and perpendicular to the long axis of the clavicle.Results:The overall mean coracoid width was 14.8 mm±2.54 mm(range 9.2e23.3 mm)and clavicle width was 17.1 mm±2.72 mm(range 11.1e25.3 mm).Conclusion:The Asian coracoid process is smaller than its Western equivalent.More research is required to validate this conclusion as no cadaveric studies with equivalent measurement techniques have been performed on Asians.Given the potentially narrower dimensions of the Asian coracoid process,extra precautions are required to minimize the risk of iatrogenic coracoid and clavicle fractures.

Bone block transfer of coracoacromial ligament in acromioclavicular injury

A bone block transfer of coracoacromial ligament into the medullary canal of the clavicle for Grade III acromioclavicular injury was developed in an attempt to prevent occasional pullout of the ligament in the procedure described by Weaver and Dunn. Fifteen consecutive cases (12 acute, three chronic) with Grade III acromioclavicular injury were treated by this method. All but one patient regained painless full range of shoulder motion. All patients returned to previous activity. Failure of coracoclavicular reconstruction occurred in one case. Asymptomatic focal myositis ossificans developed in four cases with no functional deficit.     

Editorial Commentary: Acute Repair of the Acromioclavicular Joint Capsule and Ligaments and Deltotrapezial Fascia Could Allow Biological Healing of High-Grade Acromioclavicular Separation—Coracoclavicular Ligament Graft Augmentation Could Be Indicated if Time to Surgery Is Greater Than 3 Weeks

Surgical management of chronic acromioclavicular joint (ACJ) dislocations is a matter of controversy. In the acute setting of high-grade acromioclavicular separation, if a surgical repair of the ACJ capsule and ligaments and deltotrapezial fascia could allow biological healing of the ligaments themselves, this could be enough to restore the functional biomechanics of the joint; unfortunately, this is not true for chronic cases. In the latter situation, a surgical technique using biological augmentation such as autograft or allograft should be preferred. Time is very important for this injury, and a chronic lesion should be considered when treatment is being performed 3 weeks after trauma. The graft should be passed around the base of the coracoid or through a tunnel at the base of the coracoid itself and then at the level of the clavicle as anatomically possible to reproduce the function of the native ligaments. However, some studies have shown that passing the graft at the base of the coracoid and wrapping it around the clavicle could also achieve satisfactory outcomes. An arthroscopic technique, when used in combination, could be great to treat the associated lesions, which have a reported percentage between 30% and 49%. Finally, to restore the biomechanics of the ACJ, however, reconstruction of the acromioclavicular superior and posterior capsules together with the deltotrapezial fascia seems to be very important.
