ImportanceUnstable chest wall injuries have high rates of mortality and morbidity. In the last decade, multiple studies have reported improved outcomes with operative compared with nonoperative treatment. However, to date, an adequately powered, randomized clinical trial to support operative treatment has been lacking.ObjectiveTo compare outcomes of surgical treatment of acute unstable chest wall injuries with nonsurgical management.Design, Setting, and ParticipantsThis was a multicenter, prospective, randomized clinical trial conducted from October 10, 2011, to October 2, 2019, across 15 sites in Canada and the US. Inclusion criteria were patients between the ages of 16 to 85 years with displaced rib fractures with a flail chest or non–flail chest injuries with severe chest wall deformity. Exclusion criteria included patients with significant other injuries that would otherwise require prolonged mechanical ventilation, those medically unfit for surgery, or those who were randomly assigned to study groups after 72 hours of injury. Data were analyzed from March 20, 2019, to March 5, 2021.InterventionsPatients were randomized 1:1 to receive operative treatment with plate and screws or nonoperative treatment.Main Outcomes and MeasuresThe primary outcome was ventilator-free days (VFDs) in the first 28 days after injury. Secondary outcomes included mortality, length of hospital stay, intensive care unit stay, and rates of complications (pneumonia, ventilator-associated pneumonia, sepsis, tracheostomy).ResultsA total of 207 patients were included in the analysis (operative group: 108 patients [52.2%]; mean [SD] age, 52.9 [13.5] years; 81 male [75%]; nonoperative group: 99 patients [47.8%]; mean [SD] age, 53.2 [14.3] years; 75 male [76%]). Mean (SD) VFDs were 22.7 (7.5) days for the operative group and 20.6 (9.7) days for the nonoperative group (mean difference, 2.1 days; 95% CI, −0.3 to 4.5 days; P = .09). Mortality was significantly higher in the nonoperative group (6 [6%]) than in the operative group (0%; P = .01). Rates of complications and length of stay were similar between groups. Subgroup analysis of patients who were mechanically ventilated at the time of randomization demonstrated a mean difference of 2.8 (95% CI, 0.1-5.5) VFDs in favor of operative treatment.Conclusions and RelevanceThe findings of this randomized clinical trial suggest that operative treatment of patients with unstable chest wall injuries has modest benefit compared with nonoperative treatment. However, the potential advantage was primarily noted in the subgroup of patients who were ventilated at the time of randomization. No benefit to operative treatment was found in patients who were not ventilated.Trial RegistrationClinicalTrials.gov Identifier: NCT01367951

Hip arthroscopy has been shown to offer minimally invasive access to the hip joint compared with standard open arthrotomy. The use of arthroscopy for diagnosing and treating disorders about the hip continues to evolve. This study describes a case that involves arthroscopic removal of a bullet from a low-velocity gunshot wound. The patient sustained a gunshot wound that entered the abdomen and traversed the small bowel, sigmoid colon then penetrated the urinary bladder before ending up in the medial wall of the acetabulum. After surgical repair of the viscus, the bullet was retrieved from the hip joint using standard arthroscopic portals and a fracture table. A number of issues led to the decision to use arthroscopy. Most importantly was the need to minimize soft tissue dissection, which was required to access the bullet, without interfering with previous wound at the suprapubic area. The risks of potential bullet fragmentation and migration, as well as a possible abdominal compartment syndrome were considered before proceeding. Arthroscopy allowed adequate inspection of the articular surface, irrigation of the joint, and removal of the foreign body while avoiding an invasive arthrotomy with its associated morbidity and soft tissue disruption. This surgical technique afforded a very satisfactory outcome for this patient and serves as a model for others when encountering a similar injury pattern in a trauma patient. It is a procedure that can be performed safely, quickly, and with minimal complications for surgeons with experience in arthroscopy of the hip joint.

Tibial tubercle avulsion fracture with simultaneous patellar tendon avulsion is a rare injury that has only ever been reported in adolescents; the diagnosis and management of this combined lesion has not been described in the adult population. A healthy 62-year-old male presented with acute knee pain and an inability to walk after a fall on ice. Radiographs demonstrated a displaced fracture of the tibial tubercle; patellar tendon integrity could not be verified by ultrasonography. Intraoperatively, the patient was found to have a distal avulsion of the patellar tendon in addition to tubercle fracture. First, the tendon was secured to the tubercle fragment with transosseous sutures. A novel slotted-plate construct was used to fix the tubercle fragment prior to tightening the sutures. Postoperatively, the patient was permitted to bear weight as tolerated with the operative knee immobilized in extension. After six weeks, knee range of motion was gradually increased using a hinged brace. At one year, the patient had achieved excellent range of motion (full extension to 135 degrees of flexion) and strength (5/5 knee flexion and extension) without residual pain or complications. This case represents the first description of diagnosis, management, and rehabilitation of a combined tibial tubercle fracture with distal patellar tendon avulsion in an adult. The unique construct, a slotted-plate over transosseous sutures, provided excellent results and likely has further applications.
