Implant-associated fracture of the tibial plateau in cementless medial unicondylar knee prosthesis : Locking plate osteosynthesis
Oper Orthop Traumatol. 2023 Oct 19. doi: 10.1007/s00064-023-00829-3. Online ahead of print.ABSTRACTTHE PROBLEM: Cementless medial unicondylar knee prostheses with mobile inlays have proved to be successful and are increasingly being used worldwide; however, there is a risk of fracture of the medial tibial plateau in the postoperative healing phase.THE SOLUTION: In most cases we observed split fractures starting from the keel of the implant. These can be treated with a small posteromedial locking plate, whereby the upper screws are inserted through the keel slot and then interlocked. This achieves an optimally strong bond b...

Treatment of symptomatic end-stage osteoarthritis of the ankle with anterolateral approach and an anatomical plate
Oper Orthop Traumatol. 2023 Oct 16. doi: 10.1007/s00064-023-00831-9. Online ahead of print.ABSTRACTOBJECTIVE: The aim of this paper is to describe the anterolateral approach using an anatomical plate for ankle arthrodesis and to present the first mid-term results with this technique in a high-risk population.INDICATIONS: The indication for arthrodesis of the ankle joint with this described technique is moderate to severe osteoarthritis of the ankle.CONTRAINDICATIONS: In addition to the general contraindications typical of any operation, there is a specific contraindication in cases of active infection of the soft tissues a...

Open lift-drill-fill-fix for medial osteochondral lesions of the talus: surgical technique
In this study we describe the open Lift, Drill, Fill, Fix (LDFF) technique for medial osteochondral lesions of the talus with an osteochondral fragment. As such, the lesion can be seen as an intra-articular non-union that requires debridement, bone-grafting, stabilization, and compression. The LDFF procedure combines these needs with access through a medial distal tibial osteotomy.INDICATIONS: Symptomatic osteochondral lesion of the talus with a fragment (≥ 10 mm diameter and ≥ 3 mm thick as per computed tomography [CT] scan) situated on the medial talar dome which failed 3-6 months conservative treatment.CONTRAINDICAT...

Surgical treatment of high-grade spondylolisthesis
Oper Orthop Traumatol. 2023 Oct 10. doi: 10.1007/s00064-023-00830-w. Online ahead of print.ABSTRACTOBJECTIVE: Establishment of a physiological profile of the spine via reduction of the kyphotic slipped vertebra in the transverse and sagittal planes. Achieving solid fusion. Improvement of preoperative pain symptoms and prevention or elimination of neurological deficits.INDICATIONS: High-grade spondylolisthesis (Meyerding grade 3 and 4) as well as spondyloptosis after conservative treatment and corresponding symptoms. Serious neurological deficits, hip-lumbar extensor stiffness, are emergency indications.CONTRAINDICATIONS (C...
