Introduction: Intracomparemental   pressure  were  measured  by  the  wick  catheter  technique  in  32  compartments  of  32  post  traumatic  patients  who  were  clinically  suspected  of  having  acute  compartment  syndromes.  A  pressure  of  zero  millimeters  of  mercury  was  used  as  an  indication  for  normal  compartment  enough  for  being  excluded  in  any  subject.
Material  and  Method:  Signs  and  symptoms  were  examined  in  subjects  based  on  clinical  definitions  before  measuring  intracompartmental  pressures.  Paresthesia, tensness, pain  in  passive  extension, pain  in  active  extension, paralysis, pulselessness, capillary  filling  and  pallor  of  each  subject  were  marked  to  be  used  for  comparison  with  the  value  of  intraucompartmental  pressure.
Results:  Pain  were  present  in  all  subjects  as  the  most  earliest  sign  while  the  skin  pallor  appeared  to  be  the  latest  one.The  lowest  values  of  pressure  were  seen  together  with  pain  and  paresthesia  even  below  the  10  mmHg  among  the  subjects.
In  our  cases  when  ever  the  pressure  values  of  the  affected  compartment  increased.  The  number  of  present  signs  and  symptoms  also  increased.
‍‍Conclusion:  Positive  regression  of  the  mentioned  correlation (r=0.69)  implies  that  the  value  of  intracompartmental  pressure  could  be  indicative  of  the  more  complications  associated  with  more  sign  and  symptoms.
Since  different  signs  and  symptoms  were  present  in  our  subjects  even  with  the  same  value  of  pressure. The  diagnosis  and  apporching  to  compartment  syndromes  may  looks  confusing  so  measuring  intraucompartmental  pressure  by  a  wick  cartheter  seems  to  be  the  cheep.  Available  technique  in  diagnosis  and  management  of  the  cases.

Introduction: At present, bone graft is unavoidable. In fact although among the all probable bone grafts, the autograft is the best choice, but because of some situations like two coincidence surgery upon one individual, size limitation of autografts (its impossible to get a big piece of graft from patient) increasing the bloodshed contingency, infection etc, made specialist to think about the possible substitution the allograft.
Materials and Methods: Seventeen Newzealandian rabbits were divided into four groups. The graft generator group consisted of one rabbit which was genetically different from other groups. The sham group composed of three rabbits which round autografts about 4 mm in diameter from their tibia were exchanged between rights and left tibias. These grafts were not deantigenized and a 4 mm vacant hole was created to see if it will repair spontaneously within three months. The control group consisted of three rabbits received a round 4 mm tibial autografts which double deantigenization process were done over them. The test group composed of 10 rabbits, received corticocancellous (intramembranous) allografts in left tibia and corticocancellous (endocondral). Allograft in right tibia all grafts were bearing the double deantigenization process.
Results: The rate of prosperity for CCl grafts was 80% and for CCE grafts was 60%.In sham group, healing process was extremely fast (in eight weeks).
In control group, healing process was done slower until six weeks but after 12 weeks it was compensated. The vacant holes were not repaired even after three months. Statistically, there was a meaningless difference between the rates of prosperity in both groups of grafts.
Conclusion: According to statistical assays, although the prosperous numbers of CCl were more than CCE grafts but this difference was meaningless. In the basis of histological assessments if the velocity of healing process is important, the CCI grafts are recommended
