There is a relative paucity of high-level evidence that guides the treatment of displaced midshaft clavicle fractures in adolescents. Some use overhead sports or significant shortening as relative indications for surgical treatment, while others rarely consider operative intervention for these patients. The purpose of this study is to determine the effect of overhead sports participation and fracture shortening on subjective and objective outcomes after nonoperative treatment of displaced midshaft clavicle fractures in those aged 10-17 years. ⋯ Fracture shortening and sports participation do not have a significant impact in adolescents on outcomes after displaced midshaft clavicle fracture.

Comparative Study
Comparison of fusion rates between rod-based laminar claw hook and posterior cervical screw constructs in Type II odontoid fractures.
This study was aimed (i) to compare the fusion rates of rod-based laminar claw hook constructs to that of posterior C1/C2 screw constructs in odontoid fractures, and (ii) to evaluate any complications associated with claw hook/rod constructs. To our knowledge, no study in contemporary literature has presented the effects of using modern rod-based laminar claw hooks for treating odontoid fractures. Unlike laminar clamps from the 1980s, contemporary laminar hook-rod instrumentation systems provide better immobilisation of the cervical spine and allows for building reliable frame-like constructs similar to cervical screw-rod systems. ⋯ Preliminary results of this study suggest that laminar claw hook-rod systems are useful alternatives to posterior screw techniques. Moreover, the fusion rate in non-geriatric patients is comparable to that of posterior screws. Importantly, they are devoid of the disadvantages and complications posed by screw constructs. Further studies are necessary to confirm these promising results.

The interscalene block (ISB) of the brachial plexus is a common technique for anaesthesia and the treatment of postoperative pain in shoulder surgery. Despite the well-known advantages of this technique, it is not without risks that need to be identified and taken into account. The most frequent complications associated with it are of a neurological nature and most are transient. ⋯ Ultrasound guidance now makes it possible to visualise potentially dangerous structures, thus allowing us to reduce the risk of associated complications. We present the case of a patient with transient dysphonia secondary to recurrent laryngeal nerve palsy. We also discuss briefly the most common complications associated with the technique.

Rotational malalignment during femoral nailing is common despite having various intraoperative assessment methods. The cortical step sign and diameter difference sign (CSSDDS) is commonly used because of convenience, yet it lack proper scientific scrutiny and is thought to be error prone. Using a software algorithm, cross-sectional dimensions were obtained from CT scans of 22 intact adult femurs at the proximal, mid and distal diaphysis. ⋯ With the linea aspera masked behind the femur and out of view, the sensitivities significantly deteriorated to 96.4%, 77.1% and 44.1% respectively. CSSDDS is sufficiently sensitive only when strict rules are followed. It is imperative that the operator position the image intensifier in lateral view under proper magnification so that steps of less than 0.6mm around the linea aspera may be appreciated.

The main aim of this retrospective study was to present our experience on scaphoid nonunion treated with vascularised bone graft. ⋯ Vascularised bone graft is a good solution for scaphoid nonunion to enhance the healing rate especially in the presence of avascular necrosis. Proximal pole nonunions, humpback deformity and smoking are important negative factors for scaphoid nonunion despite the use of a vascularised bone graft. A trapezoidal wedge graft is necessary for the volar type nonunions with humpback deformity. 1,2 ICSRA offer an advantage with its proximity to scaphoid in all nonunion locations. Nonetheless, 4+5 ECA graft is also a good solution for proximal nonunions.
