Purpose The purpose of this study was to assess the clinical and radiological outcomes of an arthroscopically assisted fixation of type IIB fractures using a double button device. Methods Twenty‐one patients with a type IIB displaced fracture of the clavicle who received an arthroscopically assisted fixation using a double button device were enrolled from 2009 to 2011. Clinical assessment included the patient's demographics, cause of injury, delay before surgery, time for surgery, time before resuming work and sports, the Shoulder and Hand (QuickDASH) score, the Constant–Murley score and the visual pain analogue scale (VAS). Radiological examination consisted of anteroposterior and axillary radiographs. Results The median age of patients was 33 years (range 18–67). Mean follow‐up was 35 ± 8.9 months (range 24–51 months). The average delay before surgery was 3 days (range 1–7). At final follow‐up, the mean QuickDASH score, Constant score and VAS were respectively 3.2 ± 6 (range 0–25), 94.8 ± 9.9 (range 62–100) and 0.5 ± 1.2 (range 0–4). Seventeen (81 %) patients were able to resume work, including heavy manual labour, and to resume their sport activities as well. Postoperative complications included one transient adhesive capsulitis, a symptomatic acromioclavicular joint osteoarthritis and an implant failure with nonunion. Bony union was achieved in all other patients. Conclusion This study has demonstrated that the arthroscopic treatment using a double button device was effective at providing a satisfactory functional outcome, minimizing the risk of complications and presenting low implant failure and low nonunion rates in patients with Neer type IIB fractures of the distal clavicle. Such results lead us to consider this minimally invasive technique as a first‐choice treatment. Level of evidence IV.

Pharyngeal complications due to anterior cervical spine surgery (ACSS) are not rare. We describe the case of a traction diverticulum of the hypopharynx after ACSS, a complication that has not yet been reported. We discuss the possible mechanism. A review of the complications of ACSS that are of interest to the otolaryngologist is included.

Thoracolumbar vertebral fracture incidents usually occur secondary to a high velocity trauma in young patients and to minor trauma or spontaneously in older people.Osteoporotic vertebral fractures are the most common osteoporotic fractures and affect one-fifth of the osteoporotic population.Percutaneous fixation by ‘vertebroplasty’ is a tempting alternative for open surgical management of these fractures.Despite discouraging initial results of early trials for vertebroplasty, cement augmentation proved its superiority for the treatment of symptomatic osteoporotic vertebral fracture when compared with optimal medical treatment.Early intervention is also gaining ground recently.Kyphoplasty has the advantage over vertebroplasty of reducing kyphosis and cement leak.Stentoplasty, a new variant of cement augmentation, is also showing promising outcomes.In this review, we describe the additional techniques of cement augmentation, stressing the important aspects for success, and recommend a thorough evaluation of thoracolumbar fractures in osteoporotic patients to select eligible patients that will benefit the most from percutaneous augmentation. A detailed treatment algorithm is then proposed.Cite this article: EFORT Open Rev 2017;2:293–299. DOI: 10.1302/2058-5241.2.160057

Background:Avulsion fractures of the tibial intercondylar eminence are fairly common injuries requiring surgery for the optimal functional outcome. The purpose of this study was to assess the clinical and radiological outcomes of an arthroscopic treatment of displaced tibial intercondylar eminence fractures using a suspensory device.Material and Methods:Five patients with type 2 and 3 displaced tibial intercondylar eminence fractures who received an arthroscopically assisted fixation using a double button device were enrolled from 2011 to 2012. Clinical assessment included the patient demographics, cause of injury, the delay before surgery, time for surgery, time to return to work and sport, the International Knee Documentation Committee (IKDC) and Lysholm knee scores. Stability was measured with the KT-2000 arthrometer with a force of 134 N. A side to side difference on the KT-2000 examination superior to 3 mm was considered as a significant and abnormal increase in the anterior translation. Radiological examination consisted of anteroposterior and lateral radiographs, as well as computed tomography (CT) scan of the affected knee. Clinical and radiological followup was done at 1, 2, 3, 6, and 12 months postoperatively and at final followup. CT-scan was performed before surgery and at 3 months followup.Results:The median age of patients was 31 years. Mean followup was 27 ± 5.1 months. The average delay before surgery was 3 days. At final followup, the mean IKDC and Lysholm knee scores were, 93.9 and 94.5 respectively. All patients had a complete functional recovery and were able to return to work and to resume their sport activities. No secondary surgeries were required to remove hardware. No complication was noted. Bony union was achieved in all patients.Conclusion:The arthroscopic treatment of displaced tibial intercondylar eminence fractures using a suspensory system provided a satisfactory clinical and radiological outcome at a followup of 2 years.

Objectives: To evaluate the accuracy of reduction of the acetabular articular surface using an intraoperative computed tomography scanner (O-Arm) and screw navigation compared with a classical open technique. Design: Prospective matched cohort study. Setting: Tertiary referral center. Patients/Participants: Adult patients with acute acetabular fractures were included in the study. All patients were treated by 2 senior surgeons using intraoperative imaging and screw navigation. Main Outcome Measurements: The primary outcome measure was articular reduction. Secondary outcomes were radiation dosage, operative variables [operative time, time for image acquisition, intraoperative bleeding (cell saver), number of surgical plates, and number of screws], and postoperative variables (first postoperative day pain on the visual analog scale, postoperative transfusion, and hemoglobin change). P < 0.05 was considered statistically significant. Results: Thirty-five patients were treated in the inclusion period (2016–2017) and were matched to 35 cases in our database (2013–2016). Mean age was 43 years, and the most common fracture type was a both-column fracture (OTA/AO type C). Postoperative image analysis showed that reduction was achieved in 87.1% of the cases in the O-Arm group versus 64.7% in the control group (P < 0.05). Mean gap of the articular fragments was 3.6 mm in the O-Arm group compared with 5.6 mm (P = 0.01) in the control group. There was no significant difference between the 2 groups in regards to all other studied variables except a decrease in intraoperative blood loss and transfusions and an increase in surgical time with the O-Arm group. Finally, the total radiation dose was decreased using the intraoperative O-Arm compared with a routine postoperative computed tomography scan (dose length product in O-Arm: 498 mGy.cm; dose length product in historical group: 715 mGy.cm). Conclusions: Using intraoperative imaging and screw navigation for displaced acetabular fractures allow screw navigation with increasing articular surface reduction accuracy. Operative and anesthesia times were not increased, whereas radiation exposure to the patient was significantly decreased. We recommend the use of intraoperative imaging for the treatment of displaced acetabular fractures. Level of Evidence: Therapeutic Level III.

Surgical treatment of patients with thoracolumbar vertebral fracture without neurological deficit is still controversial.Management of vertebral fracture with percutaneous fixation was first reported in 2004.Advantages of percutaneous fixation are: less tissue dissection; decreased post-operative pain; decreased bleeding and operative time (depending on the steep learning curve); better screw positioning with fluoroscopy compared with an open freehand technique; and a decreased infection rate.The limitations of percutaneous fixation of vertebral fractures include increased radiation exposure to the patient and the surgeon, together with the steep learning curve for this technique.Adding a screw at the level of the fractured vertebra has the advantages of incorporating fewer motion segments with less operative time and bleeding. This also increases the axial, sagittal and torsional stiffness of the construct.Percutaneous fixation alone without grafting is sufficient for treating type A and B1 (AO classification) thoracolumbar fractures with satisfactory results concerning kyphosis reduction when compared with open instrumentation and fusion and with open fixation.Type C and B2 fractures (ligamentous injuries) should undergo fusion since the ligamentous healing is mechanically weak, increasing the risk of instability.This review offers a detailed description of percutaneous screw insertion and discusses the advantages and disadvantages.Cite this article: EFORT Open Rev 2018;3:604-613.
