Acromioclavicular joint cyst is a extremely rare condition, usually occuring in the presence of a wide communication between glenohumeral and acromioclavicular joint in patients with a full thickness rotator cuff tear. Removal of cyst only is reported with high recurrence rate. There was no case previously reported in Korea. We report a case of recurred acromioclavicular joint cyst with a massive rotator cuff tear after simple excision, which was treated by excision of cyst, acromioplasty and resection of the lateral end of the clavicle.

Fracture of the clavicle and dislocation of the acromioclavicular joint occur commonly as separate injuries. However, complete acromioclavicular dislocation with an ipsilateral clavicle fracture is quite rare. We experienced a case of acromioclavicular joint dislocation associated with fracture of clavicle and brachial plexus injury treated by open reduction and internal fixation.

We experienced acromial erosion and subsequent fracture after the treatment of Rockwood type V acromioclavicular dislocation with hook plate and coracoclavicular ligament augmentation. It was treated by using a surgical technique to address an acromial fracture and subsequent losses of reduction in acromioclavicular joint with two trans-acromial cortical screws (crossbar technique). The reduction state of acromioclavicular joint could be maintained by these two screws. Our crossbar technique could be considered as a good salvage procedure for the reduction loss caused by cutout or significant erosion of acromion after insertion of clavicular hook plate.

While non-operative treatment with structured rehabilitation tends to be the strategy of choice in the management of Rockwood type III acromioclavicular joint injury, some advocate surgical treatment to prevent persistent pain, disability, and prominence of the distal clavicle. There is no clear consensus regarding when the surgical treatment should be indicated, and successful clinical outcomes have been reported for non-operative treatment in more than 80% of type III acromioclavicular joint injuries. Furthermore, there is no gold standard procedure for operative treatment of type III acromioclavicular joint injury, and more than 60 different procedures have been used for this purpose in clinical practice. Among these surgical techniques, recently introduced arthroscopic-assisted procedures involving a coracoclavicular suspension device are minimally invasive and have been shown to achieve successful coracoclavicular reconstruction in 80% of patients with failed conservative treatment. Taken together, currently available data indicate that successful treatment can be expected with initial conservative treatment in more than 96% of type III acromioclavicular injuries, whereas minimally invasive surgical treatments can be considered for unstable type IIIB injuries, especially in young and active patients. Further studies are needed to clarify the optimal treatment approach in patients with higher functional needs, especially in high-level athletes.

We report two cases of migration of K-wires from the acromioclavicular joint to the neck. A 73-year-old man complained of right shoulder pain for one month and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 27 years earlier. Another 56-year-old man complained of left shoulder pain and neck pain for 5 years and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 25 years earlier. In both cases, we took X-rays to look for the cause of shoulder pain and discovered broken and migrated K-wires in the neck. We removed the K-wires from the trapezius muscle and the paraspinal muscle respectively. K-wire fixation technique is simple and effective but should be followed up with X-rays periodically. In addition, we should warn patients of the possibility of migration of K-wire. And it is desirable for us to avoid using K-wire near major neurovascular structures like the sternoclavicular joint and the clavicle.

견봉쇄골관절 손상은 내전 상태에서 견관절 외측에 직접 타격으로 발생하며 주로 활동력 있는 비교적 젊은 세대에서 흔하다. 손상력에 따라 주로 견봉쇄골인대 단독 손상 또는 오구쇄골인대와 함께 파열된다. 대부분의 경우 수술적 치료 없이 보존적 요법으로 해결되지만 수술적인 가료가 필요할 경우 표준으로 삼을 수술법을 선택하기 어렵다. 이에 의거해서 이 장에서는 견봉쇄골관절은 해부학적 특성을 살펴보고 특성에 따른 치료법을 소개하기로 하겠다.

Distal clavicle tunnel widening was observed in coracoclavicular ligament reconstruction with semitendinous tendon autografts in a patient with acromioclavicular joint injury. Acromioclavicular joint separation, in a 44 years-old man was treated by coracoclavicular ligament reconstruction. We have performed x-ray evaluation on 2years 10months after surgery. The immediate postoperative tunnel size was measured 4.5mm in diameter. At postoperative 2years 10month the tunnel diameter was from 9.3 to 11.4mm. But the weightbearing clavicle view showed no significant acromioclavicular joint separation. Moreover the patient complained only minor intermittent shoulder discomfort.

Clavicular hook plate is known to be an effective treatment on acromioclavicular (AC) joint injury, but there have been some reports of complications, like osteolysis and bony erosion of the undersurface of acromion. Fifty-five year old male underwent open reduction and hook plate insertion on Rockwood type 5 acromioclavicular joint dislocation. He complained of protrusion of posterior acromion at 1 month after the surgery, and acromial fracture was noted in simple radiographs. The hook plate was removed and any other treatment for osteosynthesis was refused by the patient. At the 18 months after the surgery, the patient had no pain and a full range of motion with no tenderness around the shoulder joint. After two years, plain radiographs revealed complete bony union of the acromion fracture.
