[Malunion of the distal radius: 3D planning and performance of intra- and extra-articular corrective osteotomy].

Objective: Restoration of the original anatomy with reduction of both current symptoms and risk of posttraumatic osteoarthritis.

Indications: Symptomatic intra- or extra-articular malunion due to limitation of movement and/or painful function, intra-articular step of > 1 mm, instability of the distal radioulnar joint.

Contraindications: Minimal deformity.

[Differential therapeutic Approaches in the prosthetic Arthroplasty of Finger Joints].

Degenerative changes of the finger joints often lead to various surgical treatments such as arthrodesis or artificial joint replacement. There are a lot of surgical approaches for surgeons to choose from. The different approaches with their characteristic advantages and disadvantages during surgery and for the postoperative treatment should be selected and applied based on patient-, implant- and aftercare-specific indications.

Surgical fixation techniques in four-corner fusion of the wrist: a systematic review of 1103 cases.

Background: Four-corner fusion (4CF) is a known treatment option for degenerative wrist conditions. Different techniques may be used and there is no general consensus on best implant. As such, it was the purpose of the current systematic review to compare fusion rates and outcomes depending on the fixation technique.

Bioabsorbable poly-L/D-lactide (96/4) scaffold arthroplasty as a salvage procedure in the metacarpophalangeal joint.

We report the case of a 69-year-old female patient, who developed an impressive foreign body reaction around broken metacarpophalangeal silicone implants, including serious axillary lymphadenopathy 3 years after surgery. Possible revision arthroplasties were evaluated but, due to poor bone stock, no regular implants could be used. Instead, a double RegJoint™ (Scaffdex Oy, Finland), a bioabsorbable poly-L/D-lactide implant, was used for each of the 4 metacarpophalangeal joints.

[The use of intraoperative fascicle-topographic electromyography in peripheral nerve surgery: review of the literature and clinical experience].

The intraoperative assessment of a pathological nerve segment is crucial in peripheral nerve surgery. Based on different techniques the function of a peripheral nerve is analyzed and either a neurolysis alone or a resection with subsequent nerve reconstruction is performed. Beside the morphological and histological assessment or the use of a nerve stimulator, intraoperative electrophysiology is highly useful.

Intramedullary screw fixation for metacarpal shaft fractures: a biomechanical human cadaver study.

Intramedullary cannulated compression screws have been introduced for the fixation of unstable metacarpal fractures. In the present study, this technique was compared with dorsal compression plating to evaluate its biomechanical performance in stabilizing metacarpal shaft fractures. In a first set of experiments, the biomechanical characteristics of the screws were analysed in an artificial bone model.

Survival, Neurologic Injury, and Kidney Function after Surgery for Acute Type A Aortic Dissection.

Background: To analyze survival, neurologic injury, and kidney function after acute type A aortic dissection.

Methods: A total of 445 patients undergoing surgery for acute type A aortic dissection were analyzed. Evaluation according to risk factors for mortality, neurologic injury, and kidney function was performed.
