Three-dimensional morphometric analysis of the lateral clavicle and acromion: Implications for surgical treatment using subacromial support.

SAGE Open Med 2022 21;10:20503121221091395. Epub 2022 Apr 21.

Department of Orthopedics and Trauma Surgery, Medical Center, Albert-Ludwigs-University of Freiburg, Freiburg, Germany.

Objectives: Dislocations and periarticular fractures of the acromioclavicular joint are common injuries of the shoulder girdle. When surgical intervention is indicated, subacromial support is one option to restore the alignment between scapula and the distal/lateral clavicle. Devices used for subacromial support rely on a form of subacromial 'hook'. Read More

Orthopedics 2020 Sep 7;43(5):e359-e363. Epub 2020 Jul 7.

Clavicle hook plate is a common implant for treating distal clavicle fracture. Although high bone union rate and good functional outcome have been reported, so have several complications, such as osteolysis and fracture of the acromion, loss reduction, hook impingement, and rotator cuff tear. Peri-implant fracture over the medial side of the hook plate is a rare complication. Read More

Comparison of a novel hybrid hook locking plate fixation method with the conventional AO hook plate fixation method for Neer type V distal clavicle fractures.

Orthop Traumatol Surg Res 2020 02 9;106(1):67-75. Epub 2019 Dec 9.

Department of Orthopaedic Surgery, Dankook University College of Medicine, Cheonan, Korea. Electronic address:

Background: The conventional AO hook locking compression plate (LCP) (Synthes, Solothurn, Switzerland) has only three holes for lateral fragments; therefore it is not suitable for use during the fixation of small-comminuted fragments in some cases. Recently, a novel hybrid hook LCP (TDM, Seoul, Korea) was developed to overcome this limitation. Here, we evaluated the clinical and radiologic outcomes of a novel hybrid hook LCP for Neer type V distal clavicle fractures compared to the outcomes of a conventional AO hook plate. Read More

J Long Term Eff Med Implants 2019 ;29(3):221-224

Trauma and Orthopaedic Department, Red Cross Hospital, Athens, Greece.

Osteolysis of the distal clavicle is a rare radiological manifestation. It can be of traumatic or nontraumatic origin and is usually seen in weight-lifting trainers as a result of stress-induced osteolysis of the distal clavicle, a phenomenon known as stress failure syndrome. We present a rare case of nontraumatic osteolysis of the distal clavicle in a 65-year-old, male, non-weight lifter who was referred to our outpatient clinic. Read More

Is the Clavicula Pro Humero Technique of Value for Reconstruction After Resection of the Proximal Humerus in Children?

Clin Orthop Relat Res 2017 Oct 11;475(10):2550-2561. Epub 2017 Jul 11.

Pediatric Orthopedics Department, Children's Hospital, CHU Nancy, Rue du Morvan, 54000, Nancy, France.

Background: There are several options for reconstruction of proximal humerus resections after wide resection for malignant tumors in children. The clavicula pro humero technique is a biologic option that has been used in the past, but there are only scant case reports and small series that comment on the results of the procedure. Because the longevity of children mandates a reconstruction with potential longevity not likely to be achieved by other techniques, the clavicula pro humero technique may be a potential option in selected patients.

Diagnosis and Management of Distal Clavicle Osteolysis.

Orthopedics 2017 Mar 7;40(2):119-124. Epub 2016 Dec 7.

Distal clavicle osteolysis is an uncommon condition that most commonly affects weight lifters and other athletes who perform repetitive overhead activity. Although this condition most commonly presents in young active men, it is becoming increasing more common in women with the rise in popularity of body building and extreme athletics. Distal clavicle osteolysis can be debilitating, especially in those with rigorous training regimens, preventing exercise because of pain with activities such as bench presses and chest flies.
