Shewanella species are gram-negative bacteria found in warm, temperate regions and are normal microflora of the marine environment1. Human infections are unusual and have a restricted geographic distribution. Presentation: A 45 years old lady was bitten by a crab while preparing to cook it. She developed fever and swelling of the right thumb with hemoserous discharge and blackish discolouration.Upon examination, the thumb was erythematous and swollen with a hematoma filled blister formation over the dorsal aspect. Deblistering was done and fluid samples were sent for culture and sensitivity which later returned as Shewanella Putrefaciens. Empirically she was started on IV Augmentin. Discussion: Most common clinical manifestation associated with Shewanella spp are superficial soft tissue infection1. Other reported clinical features are primary and secondary bacteremia, hepatobiliary, bone, joint and CNS infection, endocarditis, eye, ear and respiratory infection2. Antibiotics susceptibility includes aminoglycosides, 3rd and 4th generation cephalosporins, carbapenems and fluoroquinolones1. About 79% of patients have underlying conditions such as diabetes mellitus, venous congestion and heart failure; they are immunocompromised, as is our patient3. Conclusion: Proper handling of seafood during preparation should be encouraged as a simple bite may turn deadly. Initiation of antibiotics according to suspected organisms should be performed to prevent worsening of soft tissue infections.

Periplate fractures may occur after plate fixation, especially in osteoporotic and non-united bones. We present a case of locking plate fixation over an existing plate for such fractures. Case Presentation: 58 years old man slipped and fell in sitting position 8 months post left distal femur LCP. He sustained pain and swelling of the left hip. The left thigh was externally rotated and shorter than the normal side. X-rays revealed a periplate fracture extending to the subtrochanteric region. A reverse right distal femur LCP was planned. A minimally invasive approach was used. Proximal screws were removed from the original plate and new screws were inserted through both plates which were of similar material, Titanium. Discussion: Elderly population makes a large subgroup of the cases due to osteoporosis and rigidity of the LCP construct2. This fixation provides a simple method to reduce surgical time, bleeding, and preserving more blood supply to enhance fracture healing, as opposed to using nails supplemented with cerclage/cable wires. Care should be taken to use the pre-existing screw holes in the overlapping segment of the two plates, as well as similar plate materials to avoid stress risers and reduce corrosion1. Conclusion: Plate on plate osteosynthesis is a novel method that may prove valuable due to the increasing population age and unique types of fractures. Further research is needed to determine any complications related to this type of fixation.
