A 29-year-old man, who was a medical intern presented with history of recurrent shoulder dislocation. Radiographs and computed tomography imaging revealed a bony bankart lesion with glenoid bone loss of 25% with moderate Hill- Sachs lesion. Latarjet surgery was performed. At post-operative 8 months, the patient experienced pain and clicking in the left shoulder while performing cardiopulmonary resuscitation. At post-operative 1 year, magnetic resonance arthrography showed a united coracoid graft and intact posterior labrum. Left shoulder diagnostic arthroscopy and removal of Latarjet screws through a limited anterior deltopectoral approach were performed. The symptoms pain, clicking and instability sense was caused by either the prominent distal screw or the remnant suture material from the anchor which resulted in impingement of the infraspinatus muscle. We recommend the use of image intensifier to check on the position and length of the screw at the end of the surgery to avoid this complication.

Acromioclavicular joint (ACJ) injury is a common shoulder injury. There are various techniques of ACJ reconstruction. Superficial infection after ACJ reconstruction is not an uncommon complication. However, osteomyelitis post ACJ reconstruction has never been highlighted as a possible complication. Our patient is a 31-year-old male who sustained a Rockwood 5 ACJ dislocation and had anatomical ACJ reconstruction with autogenous gracilis and semitendinosus graft. Our technique involved the anatomical reconstruction of the ACJ and the coracoclavicular ligament with the usage of two bioscrews and the temporary stabilisation of the ACJ with two k-wires. As in any orthopaedic surgery, infection is often disastrous especially when the surgery involves implants. It can be disastrous with high morbidity to the patient as well as a costly complication to treat. Therefore, we wish to highlight this case as despite its rarity, osteomyelitis can be devastating to the patient and should be prevented if possible.
