Recent attention has been focused on the operative treatment of mid-shaft fractures of the clavicle. This study compares the in-vitro biomechanical properties of a pre-formed titanium clavicle plate (Acumed) to a Synthes 3.5 mm limited-contact dynamic-compression (LCDC) plate using a cadaveric osteotomy model. An osteotomy was performed on 7 pairs of human clavicles and were randomly plated with either a Synthes 3.5 mm LCDC stainless steel plate or an Acumed titanium pre-contoured clavicle plate. After plating, specimens were tested on an EnduraTEC material testing apparatus for axial compression and tension strength, as well as torsional strength in compression and tension. Biomechanical test results for plated specimens are reported for the LCDC plate and the Acumed plate, and the 2 plates are compared. This exploratory study supports investigations with larger sample sizes to determine if the Acumed pre-contoured plate differs from the LCDC plate in biomechanical properties and the clinical implications of such differences.

Introduction: The optimal management strategy for unstable distal clavicular fractures remains controversial. Recent studies on plate techniques have reported good-to-excellent outcomes with no serious complications. The questions are that: (1) Does the use of wire augmentation with locking plate in distal part (distal wire augmentation) reduce radiographic loss of reduction (RLOR) and get earlier bony union in distal clavicular fractures? (2) Which fixation methods are associated with a higher incidence of acromioclavicular (AC) joints arthritis or subluxation? We collected and analyzed clinical studies on different plate fixation methods for unstable fractures to identify the best surgical modality.

Fractures of the clavicle (Latin clavicula, little key), which mainly occur in young men, account for 2.6-4% of all fractures in adults [1]. Above the age of 65 years more clavicular fractures occur in women [1].

While the flat bones of the face, most of the cranial bones, and the clavicles are formed directly from sheets of undifferentiated mesenchymal cells, most bones in the human body are first formed as cartilage templates. Cartilage is subsequently replaced by bone via a very tightly regulated process termed endochondral ossification, which is led by chondrocytes of the growth plate (GP). This process requires continuous communication between chondrocytes and invading cell populations, including osteoblasts, osteoclasts, and vascular cells.

Background: The incidence rate of subsequent refracture after removal of the implant in mid-shaft clavicle fracture patients is relatively high. This can lead to additional medical costs and cause doctor-patient dispute. This study tries to introduce a new method to predict the refracture risk of the clavicle after hardware removal.

Article Synopsis
- Clavicle fractures are common in emergency departments, while acromioclavicular (AC) joint injuries are rare and even more so when combined with clavicle fractures.
- A 29-year-old male patient experienced both an AC joint dislocation and a midshaft clavicle fracture, leading to surgical treatment that resulted in excellent recovery and range of motion after one year.
- The case highlights the rarity of this combination of injuries and stresses the importance of timely diagnosis and investigation to achieve favorable functional outcomes, although there's still no agreement on the best treatment approach.
