Background Reported early complication rates in reverse total shoulder arthroplasty have widely varied from 0% to 75% in part due to a lack of standard inclusion criteria. In addition, it is unclear whether revision arthroplasty is associated with a higher rate of complications than primary arthroplasty. Questions/purpose We therefore (1) determined the types and rates of early complications in reverse total shoulder arthroplasty using defined criteria, (2) characterized an early complication-based learning curve for reverse total shoulder arthroplasty, and (3) determined whether revision arthroplasties result in a higher incidence of complications. . We determined local and systemic complications and distinguished major from minor complications. Results Nineteen shoulders involved local complications (9.9%), including seven major and 12 minor complications. Nine involved perioperative systemic complications (4.7%), including eight major complications and one minor complication. The local complication rate was higher in the first 40 shoulders (23.1%) versus the last 160 shoulders (6.5%). Seven of 40 (17.5%) revision arthroplasties involved local complications, including two major and five minor complications compared to 12 of 152 (7.9%) primary arthroplasties, including five major and seven minor complications. Nerve palsies occurred less frequently in primary arthroplasties (0.6%) compared to revisions (9.8%). Conclusions The early complication-based learning curve for reverse total shoulder arthroplasty is approximately 40 cases. There was a trend toward more complications in revision versus primary reverse total shoulder arthroplasty and more neuropathies in revisions. Level of Evidence Level IV, therapeutic study.

Objectives: To evaluate unilateral sacral fractures and compare those treated operatively versus nonoperatively to determine indications for surgery. Design: Prospective, multicenter, observational study. Setting: Sixteen trauma centers. Patients/Participants: Skeletally mature patients with pelvic ring injury and unilateral zone 1 or 2 sacral fractures and without anteroposterior compression injuries. Main Outcome Measurements: Injury plain anteroposterior, inlet, and outlet radiographs and computed tomography scans of the pelvis were evaluated for fracture displacement. Results: Three hundred thirty-three patients with unilateral sacral fractures and a mean age of 41 years with a mean Injury Severity Score of 15 were included. Ninety-two percent sustained lateral compression injuries, and 63% of all fractures were in zone 1. Thirty-three percent of patients were treated operatively, including all without lateral compression patterns. Operative patients were more likely to have zone 2 fractures (54%) and to have posterior cortical displacement (29% vs. 6.2%), both with P < 0.001. Over 60% of all patients had no posterior displacement. Mean rotational displacements comparing the injured side versus the intact side were no different for patients treated operatively compared with those treated nonoperatively. Conclusions: Most unilateral sacral fractures are minimally or nondisplaced. Many patients with radiographically similar fractures were treated operatively and nonoperatively by different surgeons. This suggests an opportunity to develop consistent indications for treatment. Level of Evidence: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.
Objectives: To compare pain after operative versus nonoperative pelvic ring injuries with unilateral sacral fractures. Design: Prospective, multicenter, observational. Setting: Sixteen trauma centers. Patients/Participants: Skeletally mature patients with pelvic ring injury and minimally displaced unilateral zone 1 or 2 sacral fractures and without anteroposterior compression injuries. Main Outcome Measurements: Pelvic displacement was documented on injury plain radiographs and computed tomography scans; a 10 point Visual Analog Scale (VAS) was used to evaluate pain was obtained in the anterior and posterior pelvic ring during the time of union (12 weeks). Results: One hundred ninety-four patients with unilateral sacral fractures displaced less than 5 mm, mean age of 38.7, and mean Injury Severity Score of 14.5 were included. Ninety-nine percent had lateral compression injuries, and 62% were in zone 1. Seventy-four percent were treated nonoperatively. Nonoperative patients had more zone 1 fractures (71%, P = 0.004). Nonoperative patients reported mean VAS 2.7 points higher in the posterior pelvis (P = 0.01) and 1.9 points higher anteriorly (P = 0.11) 24 hours after injury compared with patients treated operatively. After 3 months, nonoperative patients reported higher VAS scores than operative patients: 4.0 versus 2.9 posteriorly (P = 0.019) and 3.2 versus 2.3 anteriorly (P = 0.035). Conclusions: For sacrum fractures with minimal or no displacement, slight differences in the VAS were noted within 24 hours after injury or surgery, but limited differences were seen at 3 months for either operatively treated minimally or undisplaced sacrum fractures. It is unknown whether this represents clinical relevance. These differences were below the minimally important clinical difference for VAS scores for other orthopaedic conditions. Level of Evidence: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.
Objectives: To compare early complications in elderly patients with extra-articular distal femur fractures (DFFs) allowed to weight-bear as tolerated (WBAT) immediately versus patients prescribed initial touchdown weight-bearing (TDWB). Design: Retrospective cohort study. Setting: Level 1 academic trauma center. Patients: One hundred thirty-five patients 60 years or older who underwent surgical fixation of an extra-articular DFF, including the OTA/AO fracture classification of 33-A1-3, and periprosthetic fractures with a stable knee prosthesis (Lewis and Rorabeck type I or II) with at least 6 months follow-up. Intervention: Immediate WBAT or TDWB after surgical fixation of an extra-articular DFF with either an intramedullary nail or locked plate. Main Outcome Measurements: The primary outcome was a major adverse event within the first 6 months, defined as (1) early fixation failure or change in alignment leading to reoperation, (2) nonunion, or (3) deep infection. Secondary outcomes included postoperative inpatient length of stay, discharge disposition (secondary facility vs. home), malunion, mortality, and patient-reported outcomes. Results: The rate of early adverse events requiring reoperation was similar between the WBAT group (6, 10.7%) and the TDWB group (15, 19.0%; P = 0.23). There was no difference between groups with respect to length of stay, discharge disposition, malunion, and patient-reported outcomes. Conclusions: This study supports allowing carefully selected elderly patients, based on surgeon preference, to immediately weight-bear after operative fixation of an extra-articular DFF regardless of implant choice. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
IMPORTANCE Numerous studies have demonstrated that long-term outcomes after orthopedic trauma are associated with psychosocial and behavioral health factors evident early in the patient's recovery. Little is known about how to identify clinically actionable subgroups within this population.OBJECTIVES To examine whether risk and protective factors measured at 6 weeks after injury could classify individuals into risk clusters and evaluate whether these clusters explain variations in 12-month outcomes.
This study demonstrated variation in intraoperative material cost between 6 traumatologists resulting from practice variations despite similar specialty training. The cost differences resulting from practice variation reveal potential savings through increased standardization of surgical care for similar injuries. We identified high-cost items, which could lead to cost savings if used only when they will have clinical benefit.
