Periprosthetic shoulder joint infections are encountered by orthopedic surgeons mainly as complex situations which are highlighted by difficult treatment modalities. In a confirmed infection the general therapeutic principle is a surgical procedure. Several strategies orientate on the cause of an infection, the time course of postoperative symptoms, the pathogenicity of the isolated species and the specific comorbidities of the patient. ⋯ Early recognition is of paramount importance in order to prevent further spread, sepsis or even fatal outcome. Low grade infections are challenging conditions in terms of diagnosis and treatment. This article summarizes the principles of current classification, detection and treatment strategies for periprosthetic shoulder joint infections.

Case Reports
[Two-point discrimination for phantom pain: effect of a 4-week therapy in an upper arm amputee with phantom pain].
There is evidence that phantom pain is associated with a disrupted organization of the sensory cortex and that this organization can be normalized by training with two-point discrimination (TPD). In this case study a reduction in all three phantom modalities (i.e. phantom pain, phantom feeling and painful phantom sensation) and a reduction in pain level from m= 4.13/10 visual analogue scale (VAS) to m= 0.67/10 (VAS) could be observed in a patient with an upper limb amputation during a test period of 28 days with TPD. The quality of life and performance increased significantly. This can be a promising indication for a better social and work reintegration.

Spinal injections are an important treatment option in the conservative management of many spinal disorders. A large number of imaging techniques are available to achieve a precise and safe needle placement in interventional procedures. Fluoroscopy-guided injections are safe, cost effective and available in most institutions. The following article presents an overview of common fluoroscopy-guided spinal injection therapy of the lumbar spine.

Clinical Trial
[Instability pattern of acromioclavicular joint dislocations type Rockwood III: relevance of horizontal instability].
There is no evidence-based treatment algorithm established for acromioclavicular joint (AC joint) dislocation classified as type Rockwood III injury. Recent meta-analyses revealed no advantage of surgical treatment compared to the non-operative approach. Both surgical and non-surgical approaches have been reported with inconsistent results. Therefore, the hypothesis of the current study was that patients classified as having Rockwood grade III injury may have different degrees of horizontal AC joint instability. ⋯ For further treatment studies Rockwood III injuries should be distinguished in patients presenting with or without a substantial horizontal AC joint instability.

Controlled Clinical Trial
[Evaluation of the sagittal profile in patients with thoracic adolescent idiopathic scoliosis Lenke type 1 following posterior correction].
The principle philosophy of posterior spinal instrumentation and fusion (PSIF) for the treatment of adolescent idiopathic scoliosis (AIS) has changed during recent decades. In the past the treatment of AIS mainly focused on correction of the major curve in the frontal plane while the sagittal profile and balancing were only of inferior interest in treatment planning. Various long-term outcome studies have demonstrated that many AIS patients developed a flatback syndrome (decrease of thoracic kyphosis and lumbar lordosis) associated with pain. It was concluded that treatment of AIS should consider the sagittal profile and balance; however, there are only few studies addressing additional procedures, which include the correction of the sagittal profile. ⋯ The results of this study underline that the PSIF technique alone using pedicle screws leads to a satisfactory correction in the frontal plane but is associated with adverse effects on the sagittal profile (flat back syndrome), corroborating previous studies. It was further shown that significant improvements of sagittal parameters were achieved by adding techniques for the lengthening of the dorsal thoracic column. This approach can therefore be recommended for the treatment of AIS Lenke type 1.
