Introduction:Alveolar bone resorption is a significant clinical problem. Bone loss in third molar region following extraction or surgical removal not only leads to periodontal problems in second molar region but also it may lead to some serious problems like increased incidence of angle fractures. In order to reduce the risks following third molar surgery, the socket should be augmented with bone grafts. In recent days guided tissue regeneration is the most accepted and successful technique followed many authors and its efficacy has been proved.Materials and Methods:Based upon our clinical experience, the use of bio absorbable collagen wound dressing such as CollaPlugTN has achieved quick healing and more primary wound coverage. Amongst the graft materials collagen is preferable due to its high biocompatibility and hemostatic ability. This study was done to assess the regeneration of bone in the extracted third molar sockets using xenograft (CollaPlugTN-Zimmer) which was compared with the normal healing on the contra lateral side. The assessment was done to analyze post-operative healing complications and to compare the bone density formed between control site and implant site radiologically.Conclusion:On this basis of this study, the use of collaplugTN appears to be beneficial to the patient in postoperative wound healing and also for better bone formation. The use of this material was advantageous because of its simplicity of application cost effectiveness and availability. There is enhanced wound healing and early bone formation.

Closed traumatic dislocation of multiple metatarsophalangeal joints is a rare injury. Until now only one case of simultaneous dislocation of all five metatarsophalangeal joints has been reported in peer-reviewed studies. The complex anatomy of the metatarsophalangeal joints prevents the relocation of the joints in a closed manner in maximum cases. We are reporting a case of dorsal dislocation of the second to fifth metatarsophalangeal joints in the left foot after road traffic accident. Bony prominence over the plantar aspect and increased web space between toes on presentation, then incongruity of metatarsophalangeal joints has to be thoroughly checked on radiograph. Since closed reduction attempts failed open reduction was done through dorsal approach using two incisions. Button holing of the capsule with interposition of capsule and plantar plate was noted. Dorsal approach avoids damage to the plantar plate and surrounding soft tissues.

Subtalar or peritalar dislocation is the loss of contact between the articular surface of the talus distally and the calcaneum and navicular. In this paper, a case of open medial type of subtalar dislocation associated with fractured posterior facet of the talus in a 27-year-old man with a history of road traffic accident was reported. Immediate wound irrigation and open reduction under general anesthesia at the emergency room operation theater was successful followed by cast immobilization. At one-year follow-up, the patient was walking and carrying out his daily activities with mild restriction of inversion and eversion movements. Extensive wound debridement followed by immediate reduction and, when required, stabilization are the principal features of management. Open subtalar dislocation is an extremely rare injury and often poses a treatment dilemma. Early debridement and open reduction of the dislocation like in our case can give good functional outcome for an open medial subtalar dislocation at one-year follow-up. Temporary stabilization of dislocation in the form of Kirschner wires maybe needed in some cases only.
