Tibial component loosening is an important failure mode in unicompartmental knee arthroplasty (UKA) which may be due to the 6-8 mm of bone resection required. To address component loosening and fixation, a new early intervention (EI) design is proposed which reverses the traditional material scheme between femoral and tibial components. The EI design consists of a plastic inlay for the distal f...

BACKGROUND Incisional hernia is the most frequently seen long term complication after laparotomy causing much morbidity and even mortality. The overall incidence remains 11-20%, despite studies attempting to optimize closing techniques. Two patient groups, patients with abdominal aortic aneurysm and obese patients, have a risk for incisional hernia after laparotomy of more than 30%. These patie...

PURPOSE Full tissue integration without adhesion formation is still a challenge for intra-abdominal mesh materials. Purpose of this study was to investigate the adhesive potential and fibrocollagenous ingrowth of a polymer blend of polyvinylidene fluoride and hexafluorpropylene (co-PVDF), an established suture material in vascular surgery, when placed as a mesh in the intra-abdominal position. ...

BACKGROUND Although materials for secondary cranial reconstruction have evolved with time, the overall approach in terms of bone flap/implant reconstruction after necessary delay has remained constant. OBJECTIVE To present our cases series of 50 consecutive secondary cranial reconstruction patients and to describe a multidisciplinary cranioplasty approach developed to reduce morbidity, to min...

OBJECTIVE To compare the resorption characteristics of dorsal onlay cartilage autografts from the septum, auricle, and rib. METHODS Fourteen New Zealand white rabbits underwent harvesting of equal-sized septal, auricular, and costal cartilage grafts free of perichondrium. All autografts were implanted subcutaneously on the nasal dorsum and then removed after 3 months. Graft mass, chondrocyte ...

The presence of a Meckel's diverticulum in the hernial sac is called Littre's hernia. It rare complication diverticulum. We present 56-year-old male patient who complained swelling umbilical region. After clinical examination and imaging studies, we diagnosed with partially reducible underwent exploration was found to have omentum, diverticulum, part ileum within sac. segmental resection bowel,...

Deficiencies in the alveolar ridges cause multiple problems in achieving aesthetic and functional outcome of implant therapy and are commonly restored by using onlay graft from intraoral source. Careful assessment of the recipient as well as the donor site using cone beam computed tomography (CBCT) is a prerequisite to ideal treatment planning. This paper highlights the critical role of CBCT in...

Laparoscopic repair of incisional and ventral hernias has increased in popularity due to reduced pain, shorter length of stay and earlier return to work. Dynamesh Intraperitoneal onlay mesh (IPOM), a composite of polyvinylidene fluoride (PVDF) coated polypropylene (PP) was designed to utilize the properties of both materials. This retrospective study reports a single surgeon experience with la...

OBJECTIVE This report depicts the feasibility of the concomitant repair of a large direct inguinal hernia with mesh by using the intraperitoneal onlay approach after extraperitoneal laparoscopic radical prostatectomy. METHODS A 66-year-old man with localized adenocarcinoma of the prostate was referred for laparoscopic radical prostatectomy. The patient also had a 4-cm right, direct inguinal h...

PURPOSE This study evaluated an improved perfluoropolyether polymer formulation designed for use as a corneal onlay to correct refractive error. METHODS Collagen I coated perfluoropolyether lenticules were implanted in feline corneas exposing a 6-mm diameter area of lenticule surface for epithelial growth. A parallel series of sham-wounded corneas were also studied. All corneas were monitored...
