PURPOSE: Sternoclavicular joint is an amphiarthrodial joint formed by the clavicle and sternal manubrium. This joint becomes chronically unstable in case of a medial clavicle dislocation or fracture, and improper treatment could cause malformation and pain. We aimed to determine the efficacy of a novel sternoclavicular hook plate for treatment of unstable sternoclavicular joint dislocation or fracture. METHODS: Between June 2011 and December 2013, the sternoclavicular hook plate was used to surgically treat 32 adult patients with unstable sternoclavicular joint dislocation or fracture...

PURPOSE: To investigate the biomechanical performance of four different methods used for coracoclavicular (CC) ligament reconstruction in a lateral clavicle fracture repair. METHODS: Native displacement, translation, and rotation at the acromioclavicular joint of 24 fresh-frozen cadaveric shoulders were tested. A reproducible fracture in the lateral third of the clavicle was created by dissecting both CC ligaments. Each specimen was then repaired with plate fixation of the fracture and the following CC repair technique: (1) Cortical button...

INTRODUCTION: We re-designed the outpatient management of trauma at our institution to eliminate appointments if there would be no change in management or information provision. All cases referred by the Emergency Department (ED) were reviewed at a Virtual Fracture Clinic (VFC) by an orthopaedic consultant and telephoned afterwards by a senior nurse. If face-to-face review was required, it was arranged at a specialist shoulder clinic. AIMS: The primary aim of this study was to evaluate the proportion of clavicle fractures that could be discharged without physical review...

A pseudo-bone thermo-gel was synthesized and evaluated for its physicochemical, mechanical and rheological properties, with its application to treat small bone fractures. The pseudo-bone thermo-gel was proven to have thermo-responsive properties, behaving as a solution in temperatures below 25°C, and forming a gelling technology when maintained at physiological conditions. Poly propylene fumerate (PPF), Pluronic F127 and PEG-PCL-PEG were strategically blended, obtaining a thermo-responsive delivery system, to mimic the mechanical properties of bone with sufficient matrix hardness and resilience...

Midshaft clavicle fractures are a very common occurrence. The current treatment of choice involves internal fixation with superior or anterior clavicle plating, however their clinical success and particularly patient satisfaction are decreasing. The implementation of intramedullary devices is on the rise, but data describing the intramedullary canal parameters are lacking. The aim of this study is to quantify the geometry of the clavicle and its intramedullary canal, and to evaluate the effect of gender and anatomical side...

This article describes an arthroscopic technique for the fixation of clavicle shaft fractures. A viewing portal is made 2 cm anterior to the fracture site, and a working portal is made 2 cm lateral to the fracture site. The guide wire for a 4.0-mm cannulated screw is inserted through the fracture site to the medial fracture fragment under arthroscopic guidance. Through the medial fragment, the guide wire is delivered through the skin anteriorly. The fracture is reduced, and then, the guide wire is drilled back across the fracture site to the lateral fracture fragment...

PURPOSE: A clavicle hook plate is a simple and effective method for treating acromioclavicular dislocation and distal clavicle fractures. However, subacromial osteolysis and peri-implant fractures are complicated for surgeons to manage. This study uses finite element analysis (FEA) to investigate the post-implantation biomechanics of clavicle hook plates with different hook angles. METHODS: This FEA study constructed a model with a clavicle, acromion, clavicle hook plate, and screws to simulate the implantation of clavicle hook plates at different hook angles (90°, 95°, 100°, 105°, and 110°) for treating acromioclavicular joint dislocations...

Return-to-play (RTP) is a multifactorial process of retuning an injured athlete back to competition when risk for re-injury is minimized. Traditionally, these decisions are made by medical practitioners based on experience or anecdotal evidence. RTP decisions continue to be a challenging task for the medical practitioner. In the interest of advancing sports medicine for the betterment of athletes, improving the RTP decision-making process with a new paradigm has been suggested.1 It stands to clarify the intricacies used by clinicians when making RTP decisions by providing insight into the multiple factors that must be considered; not only by the athlete and medical practitioner, but all relevant parties (i...
