“…The current findings indicate that plating with a fixation stiffness in bending of (12). This is in accordance with other reports of the healing pattern after rigid plate fixation, which found a direct angiogenic bone formation, most of which was oriented along the line of the osteotomy gap; this occurs without the intervention of cartilage, whether or not compression has been applied (2,3,6,9). In areas with contact between the fragments, bone healing may take place by direct Haversian remodeling of cortex to cortex across the fracture (9,ll).…”

In order to throw some light on the controversial issue of the optimal stiffness in fracture fixation, the effects on bone healing of rabbit tibial osteotomies fixed by plates with four different degrees of stiffness were studied. The least stiff plate was made of glass fiber-reinforced epoxy; the other three were made of stainless steel. The median bending stiffness in vitro of tibial osteotomies fixed with the various plates were 13%, 17%, 61%, and 74%, related to the stiffness of intact tibiae. Transverse midshaft unilateral tibial osteotomies were fixed by the various plates, and the animals were killed after 6 weeks. The amount of periosteal callus was inversely related to the stiffness of the plates. A marked trend toward decreased strength and stiffness occurred in tibiae where the most rigid plate was used, compared with the values of those with the less rigid plates. This indicates that the stress-protecting effect of very stiff plates begins early in the healing period and is pronounced even at 6 weeks and that a steel plate of lower stiffness is more appropriate for bone healing. However, too flexible plates involve increased risk of redislocation and mechanical failure.

“…This evaluation was graded as: 1 (no pain response on manipulation of limb), 2 (mild-allows manipulation of limb through normal range of motion, but acknowledges pain by turning head or pulling away), 3 (moderate-will not allow manipulation through normal range of motion; acknowledges pain as score 2) and 4 (severe-will not allow manipulation of limb). The healing process was assessed radiologically using the following criteria; loss of sharp fracture edges 10 , loss of fracture line 18 , cortical continuity 10,19 , presence of callus 19,20 , presence or absence of primary and secondary reduction loss 1,5 , delayed union, lack of union 21 , and osteomyelitis 22 .…”

The aim of this study was to introduce the clinical and radiological results of long bone fractures in dogs each applied the new implant system called Locking Compression Plate (LCP). In the study 32 dogs with different breed age and sex treated using LCP system had diaphyseal zone long bone fractures. The study incorporated eight cases of each humeral, radial, femoral and tibial fractures. Analysis preoperative taking radiographs of fractures classified according to Unger system. Appropriate titanium plates and screws regarding to LCP system used for each cases surgery. ÖzetBu çalışmada amaç, yeni bir implant sistemi olan Kilitli Kompresyon Plak (LCP) uygulamalarının, köpek uzun kemik kırıklarındaki klinik ve radyolojik sonuçlarının ortaya konmasıdır. Çalışmada 32 adet değişik ırk, yaş ve cinsiyetteki köpekte diyafizer bölge uzun kemik kırıkları LCP sistem kullanılarak sağaltıldı. Çalışmaya 8'er adet humerus, radius-ulna, femur ve tibia kırığı dahil edildi. Preoperatif alınan radyografiler incelenerek kırıklar Unger sistemine göre sınıflandırıldı. Operasyonlarda her bir olguya uygun boyutlarda LCP sistem setlerine ait titanyum plak ve vidalar kullanıldı. Kullanılan plak boyutu, vida sayısı ve plak-vida dansitesi kaydedildi. Her olgu klinik ve radyolojik olarak 10. ve 25. günler ile 2. ve 3. aylarda değerlendirildi. Ayrıca postoperatif 10. ve 25. günlerde ilgili ekstremitedeki topallık ve ağrı duyumu skorlanarak kaydedildi. Literatür verilere göre sık karşılaşılan kırık komplikasyonları olan osteomyelitis, gecikmeli kaynama, hatalı kaynama, kaynama yokluğu bulgularına rastlanmadı. Çalışmadaki 32 olgudan 27'sinde primer kemik kaynamasıyla geri kalanlarda ise hafif kallus oluşumuyla iyileşmenin sağlandığı görüldü.

“…This process, which forms the cal lus of the medullary cavity and around the fragments of the fracture, may be considered as preparatory to the real aim of fracture repair, ossification of the fracture gap or bony union [8,9], The amount of peripheral callus varies considerably: it depends on the bone frac tured, the extent of initial displacement, the amount of investing soft tissues, their dam age at the time of injury, the extent of bone necrosis, and the degree of stability or rigid ity after reduction. Mechanical factors, espe cially the degree of movement or rigidity at the fracture site, are important [10].…”

Twenty sheep were placed under general anesthesia and five ribs (6–10) were transected at their lateral angle using a pair of rib shears. The fractures were stabilized by titanium wire mesh plates. After 4, 6, 8, 10 and 12 weeks groups of 4 animals were sacrificed and rib samples were prepared for histological examinations. The study showed that the osteosynthesis stabilized the fractures and that the healing is similar to untreated rib fractures. This osteosynthesis method is a good contribution to severe injured chest treatment.
