infection. Complete wound healing was achieved after 4 to 8 weeks,depending on the “take” of the skin grafts. Secondary skin graftingwas necessary in two patients, while revision of the donor site wasnecessary in two patients. From an aesthetic point of view, fourpatients complained about the appearance of the retroauricular skinisland. After removal of the skin island 6 months after the initialoperation, all patients judged the result as good or acceptable.Besides the free omentum flap, the free latissimus dorsi transfer is theonly option for cover of subtotal or total scalp defects. Compared tothe omentum flap, the latissimus dorsi offers more tissue, has lessdonor site morbidity, and secondary surgery such as cranial bonereconstruction is possible. Contrary to most authors, our preferreddonor vessels are maxillary artery and the external jugular vein. Toavoid any vascular compression, we use a myocutaneous flap. Theskin island must be removed secondarily. In patients where no bonereconstruction is possible or planned, the de-epithelialized skin paddlecan be used for correction of a contour defect.HIERNER R. WILHELM K.: Callotaxis lengthening of the capitate afterresection of the lunate for the treatment of stage III lunate necrosis – a10 year follow-up. J. Hand Surg., <strong>2006</strong>; 31B: 35.Background: In order to reduce the risk of iatrogenic devascularizationof the capitate in the conventional GRANER-II technique, thecallotaxis lengthening techique of ILIZAROV has been used aftercapitate osteotomy between the middle and distal third of the capitate.Patients and methods: Since november 1993 the callotaxislengthening technique has been used to gradually lengthen thecapitate after resection of the lunate in stage IIIa NECROSIS in 23patients.Results: Results of 10 patients with a follow-up of more than five yearsshowed rapid and sufficient callus formation in every patientregardless of age.Conclusion: The callotaxis lengthening modification of the Graner-IIoperation provides all advantages, and avoids the major inconvenientof the traditional Graner-II-operation. There was no increased rate ofdisturbed fracture healing. Results of the DTPA-Gadullinium MRIstudydid not show any significant impairment of vascularization withinthe region of the capitate bone. With the "intrinsic bone formation",contrary to every other intercarpal arthrodesis at the wrist, there is noneed of an additional bone graft.86
