[Surgical decompression of the superficial radial nerve: Wartenberg syndrome].
Open decompression of the superficial radial nerve is performed at the distal forearm in cases of circumscript entrapment. Broad-based entrapments can be treated by endoscopically assisted decompression. ⋯ Surgical decompression of the superficial radial nerve yields good to excellent results regarding pain reduction and sensory function.

Case ReportsTreatment of periprosthetic acetabular fractures after previous hemi- or total hip arthroplasty: Introduction of a new implant.
Treatment of displaced periprosthetic acetabular fractures in elderly patients. The goal is to stabilize an acetabular fracture independent of the fracture pattern, by inserting the custom-made roof-reinforcement plate and starting early postoperative full weight-bearing mobilization. ⋯ In case of largely destroyed supraacetabular bone or two-column fractures according to Letournel additional synthesis via an anterior approach might be necessary. In these cases partial weight bearing is recommended.

Clinical Trial[Ligament reconstruction in extensor tendon dislocation].
Stabile recentering the extensor tendon over the top of the head of the metacarpal to restore the exact tension and the direction. ⋯ In all 16 patients good or very good results were achieved. There were no recurrences of tendon dislocations, no MP joint contractures, and only a few minor extensor tendon adhesions.

Case Reports[Masquelet technique for the treatment of large dia- and metaphyseal bone defects].
Treatment of large dia- and metaphyseal bone defects (> 3 cm) with two surgical interventions with an interval of 4-8 weeks. ⋯ A total of 6 patients (4 men, 2 women) aged 15-66 years with average bone defects of 7 cm (range 4-10 cm) were treated using the Masquelet technique. There were 2 aseptic femoral nonunions and 4 tibial nonunions (2 septic and 2 aseptic nonunions). One case was a periprosthetic tibial bone defect. Bone stabilization after debridement was performed using ring fixators on the tibia and an intramedullary nail and a locking plate on the femur, respectively. The second surgical intervention was performed after 6-9 weeks. In 3 of the 4 tibial cases, internal fixation was performed during this intervention. The iliac crest and the RIA (reamer-irrigator-aspirator) technique were used for cancellous bone grafting. Amputation after breakage of the plate was necessary in the patient with the periprosthetic bone defect. Nonunion at the docking site required cancellous bone grafting in 1 patient. All 5 patients were able to perform full weight-bearing without pain after 6 months. The Ilizarov fixator was removed 5 months after the second surgical intervention in a 15-year-old patient. None of the other implants were removed.

[Treatment of posttraumatic cubitus varus in children and adolescents. Supracondylar humeral osteotomy using radial external fixation].
Precise adaptable fixation of a supracondylar humerus osteotomy with a radial/lateral external fixator to correct posttraumatic cubitus varus. ⋯ Adequate healing is usually expected within 6 weeks. At this time the external fixator can be removed in the fracture clinic. Because the whole operation is performed in an extraarticular manner and the mobility of the elbow is not affected, deterioration of function has never been observed. Also regarding the cosmetic/anatomical situation, good results are expected because they were already achieved intraoperatively.
