The main questions it aims to answer are:\n\nAre surgeons willing to allow inclusion of their patients into such a trial? Are patients willing to participate in such a trial? Will patients be compliant with assigned weight bearing status in such a trial? Can good patient follow-up be obtained in such a trial? Is participation in such a trial safe?\n\nPatients from 7 medical centers will be enrolled, and randomized to immediate weight bearing as tolerated (WBAT) versus delayed WBAT (for 6-12 weeks). Feasibility metrics revolving around enrollment, follow-up, and documentation will be monitored, as well as medical and surgical complications. This pilot study will help inform feasibility and design of a larger definitive multicenter randomized controlled trial (RCT) on this topic.","Early weight bearing is frequently allowed and encouraged following fixation of hip and femoral and tibial shaft fractures, while periarticular and pelvis and acetabulum fractures are often prescribed 6-12 weeks of restricted weight bearing. Early weight bearing has been shown to be associated with a number of benefits following fixation of various lower extremity fractures, and delayed weight bearing is associated with an increased risk of medical complications and delayed improvement in functional outcomes. The risks associated with delayed weight bearing have encouraged clinicians to consider the safety of early weight bearing after fixation of various lower extremity fractures.\n\nRetrospective studies have shown low rates of hardware failure with early weight bearing following fixation of fractures for which early WBAT has not traditionally been allowed, including fractures of the pelvis, acetabulum, distal femur, proximal tibia, and distal tibia. Randomized controlled trials with ankle and distal femur fractures have shown no difference in rates of early hardware failure between early and delayed weight bearing. However, high-quality studies in pelvis and acetabulum are lacking.\n\nA definitive RCT on early versus delayed WBAT after fixation of pelvis and acetabulum fractures is necessary, and this would focus on important outcomes such as surgical and medical complications, patient-reported functional status, and timing of return to work or activities of daily living. However, a pilot trial of adequate size is needed to highlight 1) if participant enrollment is feasible (from a surgeon and patient perspective), and 2) if appropriate follow-up and compliance with documentation can be achieved. A pilot trial would also help establish the safety of such a trial, as perioperative complications would be monitored.\n\nThe completion of this pilot trial will assist with the design and implementation of a definitive RCT that will compare patient-relevant outcomes of immediate versus delayed WBAT following fixation of pelvis and acetabulum fractures.\n\nRESEARCH QUESTION Is a randomized controlled trial (RCT) of immediate versus delayed weight bearing following fixation of fractures of the pelvis and acetabulum feasible?\n\nSCIENTIFIC AIMS The proposed feasibility trial will address the paucity of high-quality data regarding the safety and feasibility of early weight bearing following fixation of pelvis and acetabulum fractures. A high amount of variability exists with these fractures with regard to the severity of bony, soft tissue, and non-orthopaedic injuries, so our feasibility criteria include: 1) 25% overall patient enrollment (with surgeon and patient agreement to participate in 50% of eligible cases each), 2) \\>90% follow-up at 3 months), 3) 100% correct documentation of weight bearing status, and 4) 100% correct documentation of primary outcome of reoperation.\n\nHYPOTHESIS The investigators hypothesize that the feasibility criteria will be met, and that this pilot study will inform the design and implementation of a definitive RCT on this topic.",[19,20],"Pelvis Fractures","Acetabulum Fractures",[22,19,20,23,24],"Weight Bearing","Immediate Weight Bearing","Early Weight Bearing","INTERVENTIONAL","TREATMENT",[28],"NA",{"count":30,"type":31},200,"ESTIMATED",[33,38,42,47],{"type":14,"name":34,"description":35,"armGroupLabels":36},"Immediate Weight Bearing Pelvis","Patient with a pelvis fracture may be randomized to be immediately weight bearing as tolerated after surgery.",[37],"Patient who has a pelvis fracture treated operatively",{"type":14,"name":39,"description":40,"armGroupLabels":41},"Delayed Weight Bearing Pelvis","Patient with a pelvis fracture may be randomized to be delayed weight bearing as tolerated (either non-weight bearing, foot flat, or toe touch weight bearing per surgeon discretion) for 6-12 weeks after surgery.",[37],{"type":14,"name":43,"description":44,"armGroupLabels":45},"Immediate Weight Bearing Acetabulum","Patient with an acetabulum fracture may be randomized to be immediately weight bearing as tolerated after surgery.",[46],"Patient who has an acetabulum fracture treated operatively",{"type":14,"name":48,"description":49,"armGroupLabels":50},"Delayed Weight Bearing Acetabulum","Patient with an acetabulum fracture may be randomized to be delayed weight bearing as tolerated (either non-weight bearing, foot flat, or toe touch weight bearing per surgeon discretion) for 6-12 weeks after surgery.",[46],[52,56,60,64],{"measure":53,"description":54,"timeFrame":55},"Study enrollment rates of eligible patients","Target enrollment of 50% of patients (surgeon agreement to enroll patient) and 50% of patients eligible for inclusion to agree to participate in study","Within 72 hours after surgery",{"measure":57,"description":58,"timeFrame":59},"Clinic follow-up rates for patients enrolled in study","\\>90% target follow-up of patients at 3-month postoperative visit","3 months",{"measure":61,"description":62,"timeFrame":63},"Correct documentation of randomized weight bearing status in medical charts of patients","Target 100% correct documentation of assigned weight bearing status in postoperative medical documentation (both in-hospital documentation and during follow-up visits)","12 months",{"measure":65,"description":66,"timeFrame":63},"Correct documentation of secondary outcome of reoperation in medical documentation","Target 100% correct documentation of secondary outcome of reoperation in medical documentation during follow-up visits",[68],{"measure":69,"description":70,"timeFrame":63},"Patient reoperation for any reason in the postoperative period","Track number of all-cause reoperations in all patients in medical documentation postoperatively","ALL","18 Years",null,false,{"inclusion":76,"exclusion":77,"raw_text":78},[],[],"Inclusion Criteria:\n\n1.
