“…Osseointegration is the essential and pivotal requirement for the long‐term success of the implant to maintaining the mechanical stability with the surrounding bone tissue. Previous researches 26,27 have demonstrated that pure Ti implant may sometimes lead to the direct bonding to the bone tissue through its native oxide surface under press‐fit condition. However, in our study, the implant surface of Ti alloy was in poor contact with bone tissue, and a typical layer of fibrous tissue was always emerging at the interface.…”

In this study, we present a novel coating with Zn-releasing ability that promotes osseointegration of Ti6Al4V implants. The coatings were prepared by a sol-gel technique, and nanosized Zn-containing b-tricalcium phosphate particles were added to the Ca(NO 3 ) 2 -P 2 O 5 -HPF 6 sol system to incorporate Zn ions into fluoridated hydroxyapatite (FHA) coatings. The derived Zn-releasing fluoridated hydroxyapatite (ZTFHA) coatings demonstrated a slow and sustained Zn release behavior. The ZTFHA coatings were able to support cell growth of osteoblastlike cell cultures and promoted an obvious increase in cell viability compared with FHA coating alone. The histological analysis of the ZTFHA coating showed direct bonding to bony tissue and significantly higher bone contact than with FHA coating alone. The ZTFHA coating with its slow and sustained Zn release shows promise as a medium for significantly enhancing osseointegration and allowing cementless stable fixation of orthopedic implants.

“…Montes considered that living and functional bone tissue formation around the implants results in osseointegration [25,28]. Success of osseointegration depends on certain factors [33], such as implant biomaterial and superficial properties (topography and surface roughness) [4,10,11,18,19,22], appropriate bone quantity and quality [15], systemic factors and no surgical complications, such as bone overheating and contamination [4,24], and peri-implantitis [32,36]. In our study, osseointegration of all cases was attained from the clinical aspect.…”

Purpose The aim of this study was to evaluate the early clinical outcome of reconstruction with modular hemipelvic prostheses after pelvic sarcoma resection. Methods We retrospectively reviewed eight patients between 2004 and 2007 who had periacetabular resections and reconstruction with a modular hemipelvic prosthetic system for pelvic sarcoma with a mean follow-up of 27 (range,10~54) months. Oncology outcome was assessed with survival rate, local recurrence rate, International Society of Limb Salvage (ISOLS) score and complications. Two patients had types I and II (periacetabular and ilium) pelvic resections, three had types II and III (periacetabular and pubis) pelvic resections and three had type I , II and III (ilium, periacetabular and pubis) pelvic resections. Nobody received chemotherapy or radiotherapy. Results Five patients were free of disease; three patients died of disease. The overall survival rate was 62.5%. None had local recurrence, and 37.5% had metastasis. The mean ISOLS score was 19.5. No one had deep infection or dislocation. Conclusions Reconstruction with a modular hemipelvic prosthetic system after periacetabular resection is a promising method because of the acceptable complication rate and satisfactory functional outcome.

“…Early work from the late 1970s to early 1990s proved HD formation was dependent on implant bulk material, smooth surfaces promoted HD formation compared to rough surfaces, and adsorbed protein content controlled HD formation (a detailed history of these early studies may be found elsewhere.) [ [387] , [388] , [389] , [390] , [391] , [392] , [393] , [394] , [395] ] Parallel observations were being made from groups investigating implant osseointegration; osseointegration was dependent on implant material, rougher surfaces promoted osseointegration, and adsorbed protein content controlled osseointegration [ [396] , [397] , [398] , [399] , [400] , [401] , [402] ]. Since then, only a handful of studies have confirmed that physicochemistry and topography control HD in vitro [ 403 ] and in rat models [ 384 , [404] , [405] , [406] ], and specifically that HD formation (in rats at least) is generally higher on zirconia than titanium [ [407] , [408] , [409] ].…”
