Abstract Background:Bone tendon or graft exposure such as steel plate is common after severe trauma of lower extremity.The traditional repair method is to use a variety of skin flaps to cover the exposure, but the wound can not heal after operation, or the wound dehiscence, ulcer, sinus, etc. occur again after short healing, and the bone plate is exposed again.The reason for this result is that the space around the bone plate is not well closed when the flap is covered,dead space is formed, blood and exudate accumulate, hematoma forms or infection occurs, and finally the wound breaks.Also due to swelling and contracture after flap operation,the tension of the suture between the flap and the receiving area is too large and becomes thin and cracked, forming an exposed state.In order to solve the above problems, we have carried out the research on "Application of artificial gradient combined with fascia sleep flap in the treatment of chronic bone and steel plate exposed woods of lower extremes".Methods:In this paper, 11 cases of chronic wounds with bone exposure and skin necrosis after steel plate implantation were selected. First stage is the wound bed preparation including primary wound expansion,removal of necrotic tissue and incision of sinus wall, removal of deep necrotic bone and fibrotic scarred skin on the outer wall of steel plate to normal tissue on the outer edge of the wound, removal of precipitated peptone and purulent fur in the hole, periphery and bone space of the steel plate, and removal of tendon tissue with basal necrosis and disintegration of the wound. After vacuum sealing drainage (VSD) 1~2 weeks, the peritraumatic basal granulation tissue grew well and there was no necrotic tissue in the wound. In the second stage, the exposed bone was covered with artificial dermis, the steel plate hole or the periphery and the basal space were filled, and the exposed steel plate was completely embedded, and then the fascia sleeve flap was transplanted to cover the wound. The sural neurovascular flap was performed in 6 cases and the lateral superior malleolar artery perforator flap in 1 case. Results:The flap survived well in all 11 cases. During the follow-up of 6 months to the removal of the plate, there was no case of rupture, exposure and sinus formation.Conclusions:Artificial dermal covering combined with fascial sleeve flap transplantation can effectively avoid wound dehiscence or sinus formation caused by foreign body retention, infection and flap contracture,It has good effect in repairing chronic wounds with bone plate exposure after severe trauma of lower limbs,.

Inexpensive models of the radius with and without an internal fixation system for a mid-shaft fracture are developed and analyzed using the Finite Element Method (FEM). FE models are based on geometry obtained from simple yet effective manufacturing methods. Median trabecular and cortical bone mechanical properties for a healthy adult male are used in the FEM model. These models are used to quantify the changes in bone stresses that occur when internal fixation devices are retained after the fracture has healed. The linear static responses to tensile and torsional loads with and without bone plates are examined. The static response trends obtained agree reasonably well with current literature where more expensive modeling techniques were used. A fatigue analysis is also performed based on the FE static results coupled with S-N curves for the plate and bone material in order to predict the combined mechanical response of the bone plate system over time. Recommendations are suggested which may be used as additional guidelines to consider for bone plate system selection and determination of hardware removal.

the exploration of fracture internal fixation materials has been one of the research hotspots in the field of biomedical materials. The traditional internal fixation material for fracture is metal fixation. Although its mechanical strength is very large, it can not be degraded and absorbed in human body after implantation of human body or canine joint, which requires secondary operation to remove, which not only brings pain to patients, but also causes economic pay. [1] Therefore, the development of a biodegradable fracture internal fixation material has become the goal of many researchers. Polylactic acid (PLA) is nontoxic and harmless, has good biocompatibility and strong mechanical properties. It can be degraded in vivo after implantation. The degradation products are CO2 and H2O.[2]For the study of the feasibility of polylactic acid as a substitute for common fracture fixation materials ,18 northern Chinese pastoral dogs were randomly divided into blank group, PLA group and plate group. The data were recorded according to the Wakitani score from the first week to the fifteenth week after operation. First, all the indexes were divided into two categories by principal component analysis [3], then the blank group, steel plate group and PLA group were fitted and compared. Finally, it is concluded that PLA is more beneficial to joint repair than steel plate.

Abstract Background: After severe trauma of lower limbs, bone、tendon or plate graft exposure is common.The traditional repair method is to use a variety of skin flap transplantation to cover the exposed part, but the wound often can not heal after operation, or the wound is cracked, ulcer, sinus, bone and steel plate are exposed again after wound healing.The reason for this result is that when the flap is covered, the space around the bone plate is not well closed, forming a dead cavity, blood and exudate accumulation, hematoma formation or infection, and finally the wound ruptures again. In addition, due to the swelling and contracture of the flap after operation, the suture tension between the flap and the receiving area becomes larger, the skin becomes thinner and broken, and then the wound is formed. In order to solve the above problems, we carried out the study of artificial true skin embedding combined with fascial sleeve flap transplantation in the treatment of chronic bone plate exposed wounds of lower limbs.Methods: In this paper, 11 cases of chronic wounds with bone exposure and skin necrosis after steel plate implantation were selected. First stage is the wound bed preparation including primary wound expansion,removal of necrotic tissue and incision of sinus wall, removal of deep necrotic bone and fibrotic scarred skin on the outer wall of steel plate to normal tissue on the outer edge of the wound, removal of precipitated peptone and purulent fur in the hole, periphery and bone space of the steel plate, and removal of tendon tissue with basal necrosis and disintegration of the wound. After vacuum sealing drainage (VSD) 1~2 weeks, the peritraumatic basal granulation tissue grew well and there was no necrotic tissue in the wound. In the second stage, the exposed bone was covered with artificial dermis, the steel plate hole or the periphery and the basal space were filled, and the exposed steel plate was completely embedded, and then the fascia sleeve flap was transplanted to cover the wound. The sural neurovascular flap was performed in 9 cases and the lateral superior malleolar artery perforator flap in 2 case. Results: The flap survived well in all 11 cases. During the follow-up of 6 months to the removal of the plate, there was no case of rupture, exposure and sinus formation.Conclusions: Artificial dermal covering combined with fascial sleeve flap transplantation can effectively avoid wound dehiscence or sinus formation caused by foreign body retention, infection and flap contracture,It has good effect in repairing chronic wounds with bone plate exposure after severe trauma of lower limbs.

The study was conducted to determine the occurrence of fractures in calves and goats at Veterinary Teaching Hospital (VTH), Bangladesh Agricultural University (BAU) and to compare the efficacy of fracture treatment with external and internal fixation using splints and bone plate/wire suture respectively. Patients brought to VTH with the history of automobile accident, trauma and clinical signs suggestive of fractures were subjected to detailed physical, orthopaedic and radiographic examinations to confirm fractures. A total of 6 calves and 4 Black Bengal goats were presented to VTH with limb fractures. Fractures were treated with close reduction and external fixation with splints and bandage, and open reduction and internal fixation with wire suture and bone plate. 50% and 75% fracture cases healed properly in calves and goats respectively. Among the affected animals, 60% were females irrespective of species. Metacarpal bone was the most susceptible for limb fracture. Three were open fractures and 7 cases were closed fracture with the occurrence of 70%. The healing percentage of open fracture treated with external fixation was very poor and amputation was needed in the fractured limb. Overall treatment success rate was 60 %. Biochemical analysis revealed very significant (p<0.01) difference in serum calcium level before and after healing due to hard callus formation. This study shows that bone plating fixation give a satisfactory results to calves with fracture. Moreover, the study could help veterinarians to set up proper treatment method depending on location of fracture.
