Locked Plating versus Nailing for Proximal Tibia Fractures: A Multicenter RCT.

OBJECTIVES: The main 2 forms of treatment for extraarticular proximal tibial fractures are intramedullary nailing (IMN) and locked lateral plating (LLP). The goal of this multicenter, randomized controlled trial was to determine whether there are significant differences in outcomes between these forms of treatment. DESIGN: Multicenter, randomized controlled trial. SETTING: 16 academic trauma centers. PATIENTS/PARTICIPANTS: 108 patients were enrolled. 99 patients were followed for 12 months. 52 patients were randomized to IMN, and 47 patients were randomized to LLP. INTERVENTION: IMN or lateral locked plating. MAIN OUTCOME MEASUREMENTS: Functional scoring including Short Musculoskeletal Functional Assessment, Bother Index, EQ-5Dindex and EQ-5DVAS. Secondary measures included alignment, operative time, range of motion, union rate, pain, walking ability, ability to manage stairs, need for ambulatory aid and number, and complications. RESULTS: Functional testing demonstrated no difference between the groups, but both groups were still significantly affected 12 months postinjury. Similarly, there was no difference in time of surgery, alignment, nonunion, pain, walking ability, ability to manage stairs, need for ambulatory support, or complications. CONCLUSIONS: Both IMN and LLP provide for similar outcomes after these fractures. Patients continue to improve over the course of the year after injury but remain impaired even 1 year later.

In-Hospital Morbidity and Mortality of Traumatic Lower-Extremity Amputations.

Traumatic lower-extremity amputations often result in complications and surgical revisions. The authors report the in-hospital morbidity and mortality of traumatic lower-extremity amputations at a metropolitan level I trauma center for a large rural region and compare below-knee (BK) vs higher-level amputation complications. They retrospectively reviewed 168 adult patients during a 10-year period (2005 to 2015) who had a traumatic injury to the lower extremity that required an amputation. Main outcome measurements included amputation level, complication rates, intensive care unit (ICU) admission rates, length of stay, total trips to the operating room (OR), and Injury Severity Score (ISS). A total of 95 patients had through-knee/above-knee (TK/AK) amputations, and 73 patients had BK amputations. The majority of injuries occurred in the non-urban setting. The TK/AK group had higher ICU admission rates (76% vs 35%, P<.0001), longer overall hospital length of stay (22.0 vs 15.5 days, P=.01), more total OR trips (6.5 vs 5.0, P=.04), and higher ISS (17.0 vs 11.5, P<.0001). A complication was experienced by 64% of all patients during the initial hospitalization. The TK/AK group had higher complication rates than the BK group, including wound infection, pulmonary embolus, rhabdomyolysis, compartment syndrome, and death. Patients with TK/AK traumatic amputations have a greater burden of injury with higher complication rates, increased ICU admissions, increased length of stay, and increased ISS and require more return trips to the OR compared with patients with BK amputations.

Open Reduction Is Associated With Greater Hazard of Early Reoperation After Internal Fixation of Displaced Femoral Neck Fractures in Adults 18-65 Years.

OBJECTIVES: To determine (1) which factors are associated with the choice to perform an open reduction and (2) by adjusting for these factors, if the choice of reduction method is associated with reoperation. DESIGN: Retrospective cohort study with radiograph and chart review. SETTING: Twelve Level 1 North American trauma centers. PATIENTS: Two hundred thirty-four adults 18-65 years of age with an isolated, displaced, OTA/AO type 31-B2 or type 31-B3 femoral neck fracture treated with internal fixation with minimum of 6-month follow-up or reoperation. Exclusion criteria were pathologic fractures, associated femoral head or shaft fractures, and primary arthroplasty. INTERVENTION: Open or closed reduction technique during internal fixation. MAIN OUTCOME: Cox proportional hazard of reoperation adjusting for propensity score for open reduction based on injury, demographic, and medical factors. Reduction quality was assessed by 3 senior orthopaedic traumatologists as "acceptable" or "unacceptable" on AP and lateral postoperative radiographs. RESULTS: Median follow-up was 1.5 years. One hundred six (45%) patients underwent open reduction. Reduction quality was not significantly affected by open versus closed approach (71% vs. 69% acceptable, P = 0.378). The propensity to receive an open reduction was associated with study center; younger age; male sex; no history of injection drug use, osteoporosis, or cerebrovascular disease; transcervical fracture location; posterior fracture comminution; and surgery within 12 hours. A total of 35 (33%) versus 28 (22%) reoperations occurred after open versus closed reduction (P = 0.056). Open reduction was associated with a 2.4-fold greater propensity-adjusted hazard of reoperation (95% confidence interval 1.3-4.4, P = 0.004). A total of 35 (15%) patients underwent subsequent total hip arthroplasty or hemiarthroplasty. CONCLUSIONS: Open reduction of displaced femoral neck fractures in nonelderly adults is associated with a greater hazard of reoperation without significantly improving reduction. Prospective randomized trials are indicated to confirm a causative effect of open versus closed reduction on outcomes after femoral neck fracture. LEVEL OF EVIDENCE: Therapeutic Level III.

Incidence of pseudotumor and acute lymphocytic vasculitis associated lesion (ALVAL) reactions in metal-on-metal hip articulations: a meta-analysis.

We systematically reviewed the peer-reviewed literature to determine a pooled estimate of the incidence of pseudotumor and acute lymphocytic vasculitis associated lesions (ALVAL) in adult patients with primary metal-on-metal (MoM) total hip arthroplasty or resurfacing. Fourteen eligible articles were identified, with a total of 13,898 MoM hips. The incidence of pseudotumor/ALVAL ranged from 0% to 6.5% of hips with a mean follow-up ranging from 1.7 to 12.3 years across the studies. The pooled estimated incidence of pseudotumor/ALVAL is 0.6% (95% CI: 0.3% to 1.2%). The rate of revision for any reason ranged from 0% to 14.3% of hips, with a pooled estimate of 3.9% (95% CI: 2.7% to 5.3%).

The impact of the accreditation council for graduate medical education work-hour regulations on the surgical experience of orthopaedic surgery residents.

BACKGROUND: The advent of the eighty-hour workweek regulations generated a great deal of controversy over the potential loss of operative experience for general surgery and surgical specialty residents. We believed an investigation to review the operative experience of orthopaedic surgery residents before and after the adoption of the Accreditation Council for Graduate Medical Education duty-hour guidelines would provide important information in this debate. METHODS: The total number of surgical Current Procedural Terminology codes logged in the case-log database of the Accreditation Council for Graduate Medical Education by each second through fifth year orthopaedic resident at a single university-based program was collected from July 1, 2001, to June 30, 2005. Two groups were created from the data obtained. Group I (thirty-nine residents) included surgical codes logged for the two years prior to the implementation of the eighty-hour workweek (July 1, 2003), while Group II (forty residents) included the codes for the following two years. The average number of codes was determined for Group I and Group II. The two groups were then subdivided by postgraduate year of training. The average number of surgical codes per training year was calculated. Then the second and third year (junior) resident and fourth and fifth year (senior) resident groups were combined to create two subgroups. The mean number of surgical codes was determined for each group, and the groups were compared. RESULTS: The surgical case logs of thirty-five orthopaedic residents were reviewed during the study period. One resident left the program during the first year of the study and was excluded because of incomplete data. A total of 36,464 surgical codes were logged. The average yearly number of surgical codes per resident was 461.4. The average total number of coded procedures per resident before and after the start of the eighty-hour workweek were 455.4 and 467.3, respectively. The average yearly number of surgical codes was 432.5 for the junior residents and 491.1 for the senior residents. The average number of codes logged before and after the start of the eighty-hour workweek were 407.3 and 455.3, respectively, for the junior residents compared with 501.2 and 480.6 for the senior residents. No significant differences between the groups in any category were identified. CONCLUSION: Although many aspects of surgical training may be affected by the new work-hour restrictions, our review of the operative experience of orthopaedic surgery residents at a single institution demonstrated no significant differences before and after the implementation of the eighty-hour workweek.
