Minimal-invasive placement of screws into the posterior column of the acetabulum (PC) is challenging. Due to the saddle-shaped curvature of the medial cortical border of the PC, the standard fluoroscopic views of the pelvis cannot provide the desired safety during screw insertion. The aim of this study was to define a view tangentially to the medial cortex of the PC and to evaluate its accuracy and inter-observer reproducibility. ⋯ The "Down the PC" view is a useful addendum in the orthopaedic trauma surgeon's tool box. Using simple landmarks, it is easily to reproduce and thereby shows excellent accuracy and inter-observer agreement in order to detect medial perforation or intra-articular implant position.

Supracondylar humerus fractures (SCHF) are the most common elbow fractures requiring surgical treatment in the pediatric age group. Most fractures are reduced and stabilised adequately. Yet, post-surgical malunion may occur. The purpose of this study is to evaluate our results of early revision surgery in 21 surgically treated pediatric SCHF with immediate postoperative loss of alignment and compare them with previous reports of late corrective osteotomies. ⋯ Malunion after reduction and Kirschner wires (KW) fixation of SCHF is an uncommonly reported phenomenon. When malunion is recognised after fracture healing, corrective osteotomies may carry a significant complications rate. We describe our favourable experience with early diagnosis and revision surgery of malaligned SCHF.

Case Reports
Cervical spondylodiscitis with epidural abscess after knife stab wounds to the neck: A case report.
Cervical spondylodiscitis is usually caused by pyogenic infections, associated with retropharyngeal abscesses, or due to the swallowing of foreign bodies. No cases of cervical spondylodiscitis caused by a penetrating neck injury have been published in the literature. We describe a case of cervical spondylodiscitis after multiple knife stab wounds to the lateral soft tissue of the neck. ⋯ Stab wound injuries to the neck not only bear the risk of injuries to the nerves, vessels and organs of the neck but also increase the risk of developing secondary spondylodiscitis. Specifically, cervical spondylodiscitis can result in distinct neurological symptoms, and surgical intervention should be performed in a timely manner.

Limitations in the current treatment strategies make cases with compromised bone healing challenging clinical problems. Osteogenic cell sheets (OCSs), fabricated from rat bone marrow stromal cells (BMSCs), contain enriched osteoblasts and extracellular matrix. Here, we evaluated whether the minimally invasive percutaneous injection of OCSs without a scaffold could be used as a treatment to increase bone regeneration in a critical fracture healing model. ⋯ Biomechanical testing revealed a significantly higher maximum bending load in the OCS group compared with that in the control group. The results of the present study demonstrate that the injection of entire OCSs can enhance bone regeneration and lead to bony union in a critical fracture healing model. Therefore, this procedure offers a minimally invasive technique to promote hard tissue reconstruction and, in particular, bone repair strategies for cases with compromised bone healing.

Locked minimally invasive plating and fourth generation nailing potentially could reduce the complication rate in the treatment of trochanteric femur fractures by its rotational stability and providing better lateral cortical support. The purpose of this study was (1) to compare the biomechanical properties of the Percutaneous compression plate (PCCP) and the Intertan nail (IT) with regards to implant failure and (2) to assess dynamic stability coefficients in an unstable AO/OTA 31A2.2 fracture model. ⋯ Biomechanical study.
