Many procedures described for operative management of acromioclavicular joint separations entail transfer of the coracoacromial ligament. We sought to describe the anatomy and morphology of the pectoralis minor tendon better, to assess its anatomic potential as a substitute for sacrificing the coracoacromial ligament, and to compare the ultimate tensile strength of the pectoralis minor with that of the coracoacromial ligament and detached coracoclavicular ligament. The morphology of the pectoralis minor tendon was carefully delineated and compared with that of the coracoacromial ligament, and 10 paired fresh-frozen cadaveric shoulders were tested to failure by applying a single uniaxial tensile load. Anatomic study of the pectoralis minor tendon confirmed its adequacy as a source of local autograft tissue in acromioclavicular joint reconstruction. We hypothesize that, in cases of acromioclavicular joint separation necessitating operative intervention, the use of the pectoralis minor tendon as a potential source of autograft tissue is anatomically feasible and it is slightly stronger than the coracoacromial ligament. 相似文献

Evaluation and management of acromioclavicular joint injuries 总被引:5,自引:0,他引:5
Dumonski M Mazzocca AD Rios C Romeo AA Arciero RA 《American journal of orthopedics (Belle Mead, N.J.)》2004,33(10):526-532
The acromioclavicular joint is stabilized by the coracoclavicular and acromioclavicular ligaments and by the trapezius and deltoid muscles. Joint dislocation commonly results from a direct blow to the acromion. Injury types I through III are generally treated nonoperatively, whereas types IV through VI are treated operatively. Nonoperative protocols should always begin with ice and immobilization. Operative techniques include acromioclavicular ligament repair, dynamic transfer of the conjoined tendon, coracoclavicular ligament reconstruction, and coracoacromial ligament transfer. The goal with any injury type should always be full return to the patient's preinjury condition. 相似文献

The purpose of this article is to describe the indications, operative technique, and postoperative rehabilitation protocol for treatment of complete acromioclavicular separations. A modified Weaver and Dunn technique is described, with a detailed harvesting procedure of the coracoacromial ligament, along with a wafer of bone for anatomical reconstruction of the coracoclavicular ligaments. A suture anchor is used to provide temporary stability to the acromioclavicular joint while the transferred coracoacromial ligament heals in the new position. 相似文献

The coracoid process is the origin of the trapezoid ligament, the deltoid ligament, and the coracoacromial ligament (CAL). Detailed knowledge about their anatomy is crucial for surgical procedures such as the reconstruction of the coracoclavicular ligaments or coracoid transfer. Although the coracoclavicular ligaments are considered important stabilizers of the acromioclavicular joint and are therefore highly protected, the CAL seems less important, which is why it is generally cut during coracoid transfer procedures. However, there is evidence that the CAL contributes to muscular balance and stabilization of the shoulder girdle. Therefore, an individual approach should be considered during coracoid transfer to save at least parts of the CAL. 相似文献

Chronic instability of the acromioclavicular joint (AC joint) results if the initial acromioclavicular joint luxation has been missed or if the rehabilitative or surgical treatment was not successful. Late repairs after a traumatic luxation are difficult to deal with because the biological healing response for reconstitution of the ligaments seems to be compromised. A meticulous diagnostic examination should be performed paying special attention to the character and direction of instability (static versus dynamic and vertical versus horizontal). For this purpose a specified classification system should be used (Hedtmann and Heers). A new surgical technique for stabilization of chronic AC joint instability has been established and biomechanically evaluated. The technique includes an augmented modified coracoacromial ligament (only the medial half of the ligament) transfer supplemented by coracoclavicular polyester augmentation. In an in vitro model the technique was shown to restore anterior and superior translation of the intact AC joint. An increase of translation compared to the level of the intact joint was statistically significant only for the posterior direction (127%, 3.8 mm intact versus 4.6 mm following reconstruction; p<0.05). Therefore, for further improvement of the technique some form of acromioclavicular ligament reconstruction (posterosuperior) could be profitable. In conclusion the presented surgical technique (augmented CA ligament transfer) reveals promising biomechanical results in an in vitro model and may serve as an alternative to current coracoclavicular ligament reconstruction techniques using autologous tendon grafts. 相似文献

Subcoracoid acromioclavicular dislocations are rarely seen injuries of the shoulder. We present a patient with multiple injuries and a subcoracoid acromioclavicular dislocation resulting from a falling injury. Physical examination revealed painful mechanical block at 90 degrees of abduction and swelling in the acromioclavicular region. Diagnosis was made with direct radiographs and computerized tomography. Treatment consisted of distal clavicular resection and coracoclavicular reconstruction with the transfer of the coracoacromial ligament over the clavicle. The patient had a pain-free shoulder after two years and was capable of performing daily activities despite the presence of coracoclavicular ossification. 相似文献

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. 相似文献

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. 相似文献

Coracoclavicular ligament reconstruction using the lateral half of the conjoined tendon 总被引:6,自引:0,他引:6
Sloan SM Budoff JE Hipp JA Nguyen L 《Journal of shoulder and elbow surgery / American Shoulder and Elbow Surgeons ... [et al.]》2004,13(2):186-190
To preserve the coracoacromial (CA) ligament, we have used the lateral half of the conjoined tendon as an autograft source to replace the coracoclavicular (CC) ligament. The purpose of this study is to compare the ultimate tensile strength of the lateral 12 mm of the conjoined tendon with that of the CA ligament and the CC ligament. Eight paired cadaveric male shoulders were tested to tensile failure with a custom pneumatic testing apparatus. Although the lateral 12 mm of the conjoined tendon was stronger than the CA ligament, this difference was not statistically significant (P =.37). However, the intact CC ligament (621 +/- 209 N) was approximately 250% stronger than either the lateral 12 mm of the conjoined tendon (265 +/- 79 N, P <.001) or the CA ligament (246 +/- 69 N, P <.001). We believe that the lateral half of the conjoined tendon is a viable alternative autograft source for reconstruction of the CC ligament in cases of symptomatic acromioclavicular joint dislocation. Though not as strong as the native CC ligaments, the conjoined tendon is slightly stronger than the commonly used CA ligament. 相似文献

Acromioclavicular joint injury is common in young individuals who suffer direct trauma to the shoulder. Treatment of acromioclavicular dislocation is controversial with regards to the indication of operative management, timing of surgery, whether to perform open or arthroscopic surgery, method of stabilisation (rigid or non-rigid) and type of graft used for repair or reconstruction. Current evidence supports conservative management for Rockwood types I and II, while types IV, V and VI benefit from surgery. The optimal management of type III injuries in high demand patients remains contentious. Surgical options include acromioclavicular fixation, coracoclavicular fixation and coracoclavicular ligament reconstruction. Few studies with a low level of evidence suggest arthroscopic techniques and anatomical ligament reconstruction have better outcomes when compared to older techniques of rigid coracoclavicular fixation. The aim of this article is to look at the current evidence and address these controversial issues. 相似文献

Sixty-three complete acromioclavicular separations were treated by 2 operative methods. Acromioclavicular wiring gave 73% acceptable results while wire or Dacron coracoclavicular loop gave 94% acceptable results. Complications, especially broken, bent, or backed-out wires were common with acromioclavicular wiring. Of 44 patients treated by acromioclavicular wiring, 5 required late distal clavicle resection and 4 of these had retained menisci. Loop fixation is mechanically superior since the loop is in the direction of the tensile forces. In acromioclavicular wiring, however, the fixation Kirschner wires are subjected to high bending moments. Loop fixation avoids violation of the acromioclavicular joint but does not restrict rotation of the clavicle. The operation is simple to perform and postoperative immobilization is minimal. Woven Dacron may be superior to surgical wire for loop fixation in that unlike wire it does not require removal by a second operation. Woven Dacron may also stimulate coracoclavicular ligament reconstitution. 相似文献
