Agricultural injuries are under reported. This work was aimed to define causes that led to the lower limb loss in paddy thresher injuries. The design of the study was a follow- up of the recipients of artificial limb from our facility a tertiary care centre. From a questionnaire given to 18 lower limb amputees who lost their limbs due to thresher injuries (of the total 35 cases presented to us) it was found that most victims were less educated males who had below knee amputations; injured late in afternoon tired; being tired they sat on the top loading machine and pushed the paddy stalks with their legs into a thresher drum which was run by power from a diesel engine. None of them had any formal training There is a need to change farm practices to significantly reduce paddy thresher injuries. Source

Criterion for patient selection and demographic comparison between the two groups, the numbers in individual groups (normal union or defective union) how the observers were blinded for the samples and control group measurements in the graphs were not mentioned. No data on actual measurement levels is given. No where it is mentioned like it is an average of all normal union or defective union in tables or diagrams. The treatment methodology maybe still focused including either conservative or surgical treatment since a displaced fracture cannot be compared with an osteotomy. The cases shall be followed up for a longer period. Some suggestions on how to blind the observers is given. In the one year period there was neither mention of the failure of treatment or complications of any of neither these 36 cases nor any drop out for follow-ups. There was also no mention of any case which initially put on conservation was changed to surgical management. The authors could have one group of patients taking this food stuff and another group who refused this food stuff. The statistical test used to compare the levels of factor is not mentioned. Mere statement that 'p' values were significant will not benefit the reader. Failure to produce X-rays even for a single case weakens the study. X-rays are needed to confirm the diagnosis of a fracture and confirm the position of implants and fracture fragments. The remaining period after confirming the fracture/implant position the case shall be followed only with marker estimation. Once the desired levels of increase or tapering of marker level achieved then X-rays can be taken to correlate with clinical findings and radiology. Union as one group and the second group shall be called as non-union or delayed union. The second group (the poor callus group) is mentioned as malunion possibly by over-sight. Probably they were meaning the non union or delayed union group or defective union as malunion. This should be preferably be written non union or delayed union. Malunion means the fracture actually unites and union process is completed. In a group of fractures (hypertrophic non unions) the callus formation is excessive, still the fracture is ununited. Thus the enzyme or markers alone cannot disclose the details of the completion of union they can herald bone formation. © 2012 Association of Clinical Biochemists of India. Source

Neurofibroma is genetic disorder characterized by tumorous growth from the neural crest cells. They not only involve various systems of interest to departments like neurological, dermatological, orthopaedic, pediatric but their manifestations also slowly evolve with different manifestations presenting at different ages. Thus they present difficulty in diagnosis and management. Here, we report a case of neurofibroma that had no specific orthopaedic symptom except a swelling. Source

Background: Electrical stimulation of fractures has been reported to enhance fracture healing. X-rays are normally used to assess union of fractures. Electrical conduction is not tried as a tool to study fracture healing. The current study focuses on electrical conduction as a diagnostic tool to assess fracture healing and new bone formation. The aim was to find if electrical resistance across the fracture can be used as a tool to study fracture healing which can be verified with simultaneous radiographs. Materials and Methods: A prospective study was conducted where 12 open fractures of tibia, including two with bone defects were evaluated. They were debrided and four-carbon ring Ilizarov external fixators were applied. Their healing was followed with clinical assessment and periodical X-rays till the endpoint of fracture union and then the rings were removed. In addition, all these cases also had application of electrical voltage in the range of 0.1-1.0 V DC in 0.1 V increments, across the two wires on either side of fracture. The output current was recorded by an ammeter connected in series. Resistance calculated for various voltages was plotted as a graph for the period of fracture treatment and the characteristics were studied. This graph was compared with the appearance of new bone in the X-rays. Results: In all cases, when the above graph stabilized, in the consecutive recordings, the X-rays showed healing (bridging callus) matching the curve and the patient was able to load the limb. The time of stabilization of this graph for a specific voltage was different in individual cases. However, for a given case, the resistance characteristics were the same for the entire voltage range of 0.1-1.0 V. Conclusion: If the resistance versus day curve stabilizes on the consecutive recordings, we can predict that the fracture is in the process of healing. This stabilization period also matched the patients' ability to comfortably load the limb and also the radiographs which showed bridging callus (healing). If this is used as a positive criterion for fracture healing in future, the radiation exposure by X-rays shall be less. Source
