Arthroskopisch-assistierte Rekonstruktion des skapholunären Bandes mit Knochen-Band-Knochen-Transplantat
Die Autoren ziehen den Schluss, dass die beschriebene Technik der Rekonstruktion des skapholunären Bandes nach ihren klinischen Ergebnissen eine verlässliche Alternative bei Läsionen vom Typ 3 und 4 nach Geissler ist. Einschränkend seien allerdings geringe Patientenzahl, 2 Patienten mit einer Verletzung vom Typ 4 und das relativ kurze Follow-up. Außerdem sei ihre Technik für sehr schmale Handgelenke nicht geeignet.

An arthroscopic-assisted minimal invasive method for the reconstruction of the scapho-lunate ligament using a bone–ligament–bone graft
We report the outcomes of an arthroscopic-assisted minimally invasive technique to reconstruct the scapho-lunate ligament using a bone–ligament–bone graft in 11 patients (11 wrists). The mean follow-up time was 29 months (range 20 to 38). The preoperative mean wrist flexion, extension, grip strength and patient-rated wrist evaluation score values were 61°, 54°, 115 N and 54, respectively. The postoperative mean values were 64°, 58°, 142 N and 15, respectively. There were no statistical differences between the pre- and postoperative wrist flexion and extension, whereas changes in grip strength and patient-rated wrist evaluation score were significant. Scapho-lunate angles decreased significantly from 69° to 60°. Based on our clinical outcomes, this method provides a reliable alterative for the reconstruction of the scapho-lunate ligament in patients with persistent Geissler type 3 and 4 lesions in the short-term. Level of evidence: IV

The use of a pyrocarbon capitate resurfacing implant in chronic wrist disorders
The present study describes the technique and results of proximal row carpectomy with resection of the head of the capitate and replacement with a pyrocarbon capitate resurfacing implant. The major indication for surgical treatment was arthritic changes on the head of the capitate. Patients were assessed by range of motion, grip strength, pain and functional scoring, and radiographic studies. In most patients, wrist function was improved and pain relief was obtained. This surgical procedure may represent a good alternative to total and partial wrist arthrodesis.

Cisplatin loaded PMMA: mechanical properties surface analysis and effects on Saos2 cell culture
Objective: Despite wide resection and systemic chemotherapy, bone tumors may present with local recurrences, metastases and pathological fractures. Application of bone cement containing antineoplastic drug to fill the defect after resection of metastatic lesions and to support implants has been suggested to prevent local tumor growth and implant failures. In this study, we aimed to demonstrate the effects of the addition of cisplatin which is a widely used antineoplastic drug for osteosarcoma, on the mechanical properties of bone cement, and to evaluate the cytotoxic effects of eluted cisplatin on Saos-2 cell culture. \r\nMethods: Two cement samples were prepared by mixing 100 mg and 300 mg of cisplatin powder with 40 g cement powder. The bone cement of the control group did not contain cisplatin. Mechanical analyses included 4-point bending, compression and shear testing. For cytotoxicity analysis, samples were incubated in Dulbecco’s Modified Eagle’s medium for 15 days. Mediums were applied to Saos-2 cell culture and cell viability was measured. Surface analyses were performed by scanning electron microscope (SEM).\r\nResults: The addition of cisplatin did not alter the mechanical properties of bone cement. It was observed that the eluted cisplatin had cytotoxic effects on Saos-2 cells. SEM analyses demonstrated cisplatin granules on the surface of cement samples.\r\nConclusion: Cisplatin maintains its cytotoxic property when released from bone cement without compromising the mechanical stability. Application of cisplatin loaded bone cement may help local control of tumor growth. We believe that our study will shed light on to these new practices for the treatment of bone cancers and will encourage future studies. Özet Amaç: Geniş rezeksiyon ve sistemik kemoterapiye rağmen, kemik tümörlerinin seyrinde lokal nüks, metastaz ve patolojik kırıklar ortaya çıkabilir. Metastatik lezyonların rezeksiyonu sonrası oluşan eksikliği doldurmak ve implantları desteklemek için antineoplastik ilaç içeren kemik çimentosu uygulanmasının, lokal tümör büyümesi ve implant gevşemelerini önlemede faydalı olabileceği öne sürülmüştür. Bu çalışmanın amacı, osteosarkom için yaygın olarak kullanılan bir antineoplastik ilaç olan sisplatinin çimentoya eklenmesinin kemik çimentosunun mekanik özelliklerine etkisinin olup olmadığını göstermek ve salınan sisplatinin Saos-2 hücre kültürü üzerine sitotoksik etkilerini araştırmaktır.\r\nÇalışma planı: Yüz mg ve 300 mg sisplatin tozu, 40 g çimento tozu ile karıştırılarak 2 grup kemik çimentosu numunesi hazırlandı. Kontrol grubundaki kemik çimentosu numuneleri sisplatin içermemekteydi. Mekanik analizler için 4 nokta bükme, sıkıştırma ve kayma testleri yapıldı. Sitotoksisite analizi için, numuneler 15 gün boyunca Dulbecco’nun modifiye Eagle sıvısında inkübe edildi. Toplanan sıvılar, Saos-2 hücre kültürüne uygulandı ve hücre canlılığı ölçüldü. Yüzey analizleri, scanning elektron mikroskobu (SEM) ile yapıldı.\r\nBulgular: Sisplatin eklenmesi, kemik çimentosunun mekanik özelliklerini değiştirmedi. Salınan sisplatinin Saos-2 hücreleri üzerine sitotoksik etkileri olduğu saptandı. SEM analizleri çimento örneklerinin yüzeyinde sisplatin granüllerinin varlığını ortaya koydu.\r\nÇıkarımlar: Kemik çimentosundan salınan sisplatin, konulduğu kemik çimentosunun mekanik dayanıklılığını etkilemeksizin sitotoksik özelliğini korumaktadır. Sisplatin yüklü kemik çimentosu uygulaması, tümör büyümesinin lokal kontrolünde yardımcı olabilir. Çalışmamızın, kemik kanserlerinin tedavisindeki yeni uygulamalara ışık tutacağına ve gelecekteki çalışmaları teşvik edeceğine inanıyoruz.
