Benefits of Rib Fixation Utilizing Low-Cost Materials: A Randomized Pilot Trial.

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) using standard rib plating systems has become a norm in developed countries. However, the procedure has not garnered much interest in low-middle-income countries, primarily because of the cost. METHODS: This was a single-center pilot randomized trial. Patients with severe rib fractures were randomized into two groups: SSRF and nonoperative management. SSRF arm patients underwent surgical fixation in addition to the tenets of nonoperative management. Low-cost materials like stainless steel wires and braided polyester sutures were used for fracture fixation. The primary outcome was to assess the duration of hospital stay. RESULTS: Twenty-two patients were randomized, 11 in each arm. Per-protocol analysis showed that the SSRF arm had significantly reduced duration of hospital stay (22.6 ± 19.1 d versus 7.9 ± 5.7 d, P value 0.031), serial pain scores at 48 h and 5 d (median score 5, IQR (3-6) versus median score 7, IQR (6.5-8), P value 0.004 at 48 h and median score 2 IQR (2-3) versus median score 7 IQR (4.5-7) P value 0.0005 at 5 d), significantly reduced need for injectable opioids (9.9 ± 3.8 mg versus 4.4 ± 3.4 mg, P value 0.003) and significantly more ventilator-free days (19.9 ± 8.7 d versus 26.4 ± 3.2 d, P value 0.04). There were no statistically significant differences in the total duration of ICU stay (median number of days 2, IQR 1-4.5 versus median number of days 7, IQR 1-14, P value 0.958), need for tracheostomy (36.4% versus 0%, P value 0.155), and pulmonary and pleural complications. CONCLUSIONS: SSRF with low-cost materials may provide benefits similar to standard rib plating systems and can be used safely in resource-poor settings.

Cost Analysis of Volar Plate Fixation Versus Plaster Cast Immobilization for Intra-Articular Distal Radial Fractures.

BACKGROUND: The aim of this study was to compare the cost-effectiveness and cost-utility between plaster cast immobilization and volar plate fixation for acceptably reduced intra-articular distal radial fractures. METHODS: A cost-effectiveness analysis was conducted as part of a randomized controlled trial comparing operative (volar plate fixation) with nonoperative (plaster cast immobilization) treatment in patients between 18 and 75 years old with an acceptably reduced intra-articular distal radial fracture. Health-care utilization and use of resources per patient were documented prospectively and included direct medical costs, direct non-medical costs, and indirect costs. All analyses were performed according to the intention-to-treat principle. RESULTS: The mean total cost per patient was $291 (95% bias-corrected and accelerated confidence interval [bcaCI] = -$1,286 to $1,572) higher in the operative group compared with the nonoperative group. The mean total number of quality-adjusted life-years (QALYs) gained at 12 months was significantly higher in the operative group than in the nonoperative group (mean difference = 0.15; 95% bcaCI = 0.056 to 0.243). The difference in the cost per QALY (incremental cost-effectiveness ratio [ICER]) was $2,008 (95% bcaCI = -$9,608 to $18,222) for the operative group compared with the nonoperative group, which means that operative treatment is more effective but also more expensive. Subgroup analysis including only patients with a paid job showed that the ICER was -$3,500 per QALY for the operative group with a paid job compared with the nonoperative group with a paid job, meaning that operative treatment is more effective and less expensive for patients with a paid job. CONCLUSIONS: The difference in QALYs gained for the operatively treated group was equivalent to an additional 55 days of perfect health per year. In adult patients with an acceptably reduced intra-articular distal radial fracture, operative treatment is a cost-effective intervention, especially in patients with paid employment. Operative treatment is slightly more expensive than nonoperative treatment but provides better functional results and a better quality of life.

Cost-Effectiveness of Treatments after Closed Extraarticular Distal Radius Fractures in Older Adults from the WRIST Clinical Trial.

BACKGROUND: This study performs an economic analysis of volar locking plate, external fixation, percutaneous pinning, or casting in elderly patients with closed distal radius fractures. METHODS: This is a secondary analysis of the Wrist and Radius Injury Surgical Trial, a randomized, multicenter, international clinical trial with a parallel nonoperative casted group of patients older than 60 years with surgically indicated, extraarticular closed distal radius fractures. Thirty-Six-Item Short-Form Health Survey-converted utilities and total costs from Medicare were used to calculate quality-adjusted life-years and incremental cost-effectiveness ratio. RESULTS: Casted patients were self-selected and older (p < 0.001) than the randomized surgical cohorts, but otherwise similar in sociodemographic characteristics. Quality-adjusted life-years for percutaneous pinning were highest at 9.17 and external fixation lowest at 8.81. Total costs expended were $16,354 for volar locking plates, $16,012 for external fixation, $11,329 for percutaneous pinning, and $6837 for casting. The incremental cost-effectiveness ratios for volar locking plates and external fixation were dominated by percutaneous pinning and casting. The ratio for percutaneous pinning compared to casting was $28,717. Probabilistic sensitivity analysis revealed a 10, 5, 53, and 32 percent chance of volar locking plate, external fixation, percutaneous pinning, and casting, respectively, being cost-effective at the willingness-to-pay threshold of $100,000 per quality-adjusted life-year. CONCLUSIONS: Casting is the most cost-effective treatment modality in the elderly with closed extraarticular distal radius fractures and should be considered before surgery. In unstable closed fractures, percutaneous pinning, which is the most cost-effective surgical intervention, may be considered before volar locking plates or external fixation.

Clinical outcome and operative cost comparison: Locked compression plate versus reconstruction plate in midshaft clavicle fractures.

OBJECTIVE: The aim of this study was to compare the clinical outcomes and operative cost of a locked compression plate (LCP) and a nonlocked reconstruction plate in the treatment of displaced midshaft clavicle fracture. METHODS: From January 2013 till March 2018, a total of 55 patients with acute unilateral closed midshaft clavicle fracture were treated with either a 3.5-mm pre-contoured LCP [32 patients; 25 men and 7 women; mean age: 35 years (range: 19-63 years)] or a 3.5-mm nonlocked reconstruction plate [23 patients; 20 men and 3 women; mean age: 31.4 years (range: 17-61 years)]. The clinical outcomes in terms of fracture union, Quick Disability of Arm, Shoulder and Hand (DASH) score, implant irritation, failure rate, and reoperation rate were evaluated retrospectively. The patient billing records were reviewed to obtain primary operation, reoperation, and total operative cost for midshaft clavicle fracture. These values were analyzed and converted from Malaysia Ringgit (RM) to United States Dollar (USD) at the exchange rate of RM 1 to USD 0.24. All patients were followed up for at least one-year duration. RESULTS: The mean time to fracture union, implant irritation, implant failure, and reoperation rate showed no significant difference between the two groups of patients. The mean Quick DASH score was significantly better in the reconstruction plate group with 13 points compared with 28 points in the LCP group (p=0.003). In terms of total operative cost, the LCP group recorded a cost of USD 391 higher than the reconstruction plate group (p<0.001). CONCLUSION: The 3.5-mm reconstruction plate achieved not only satisfactory clinical outcomes but was also more cost-effective than the LCP in the treatment of displaced midshaft clavicle fractures.

Cost-Effectiveness of Volar Locking Plate Compared with Augmented External Fixation for Displaced Intra-Articular Wrist Fractures.

BACKGROUND: The purpose of the present study was to estimate the cost-effectiveness of treating displaced, intra-articular distal radial fractures with volar locking plate fixation compared with augmented external fixation. METHODS: A cost-utility analysis was conducted alongside a randomized, clinical trial comparing 2 surgical interventions for intra-articular distal radial fractures. One hundred and sixty-six patients were allocated to either volar locking plate fixation (84 patients) or external fixation (82 patients) and were followed for 2 years. Health-related quality of life was assessed with the EuroQol-5 Dimensions and was used to calculate patients' quality-adjusted life-years (QALYs). Resource use was identified prospectively at the patient level at all follow-up intervals. Costs were estimated with use of both a health-care perspective and a societal perspective. Results were expressed in incremental cost-effectiveness ratios, and uncertainty was assessed with use of bootstrapping methods. RESULTS: The average QALY value was equivalent between the groups (1.70463 for the volar locking plate group and 1.70726 for the external fixation group, yielding a nonsignificant difference of -0.00263 QALY). Health-care costs were equal between the groups, with a nonsignificant difference of &OV0556;52 (p = 0.8) in favor of external fixation. However, the external fixation group had a higher loss of productivity due to absence from work (5.5 weeks in the volar locking plate group compared with 9.2 weeks for the external fixation group; p = 0.02). Consequently, the societal costs were higher for the external fixation group compared with the volar locking plate group (&OV0556;18,037 compared with &OV0556;12,567, representing a difference of &OV0556;5,470; p = 0.04) in favor of the volar locking plate group. Uncertainty analyses showed that there is indifference regarding which method to recommend from a health-care perspective, with volar locking plate treatment and external fixation having a 47% and 53% likelihood of being cost-effective, respectively. From the societal perspective, volar locking plate treatment had a 90% likelihood of being cost-effective. CONCLUSIONS: External fixation was less cost-effective than volar locking plate treatment for distal radial fractures from a societal perspective, primarily because patients managed with external fixation had a longer absence from work.

The ideal implant for Mayo 2A olecranon fractures? An economic evaluation.

BACKGROUND: The ideal implant for stable, noncomminuted olecranon fractures is controversial. Tension band wiring (TBW) is associated with lower cost but higher implant removal rates.On the other hand, plate fixation (PF) is purported to be biomechanically superior, with lower failure and implant removal rates, although associated with higher cost. The primary aim of this study is to look at the clinical outcomes for all Mayo 2A olecranon between PF and TBW. The secondary aim is to perform an economic evaluation of PF vs. TBW. MATERIALS AND METHODS: This is a retrospective study of all surgically treated Mayo 2A olecranon fractures in a tertiary hospital from 2005-2016. Demographic data, medical history, range of motion, and complications were collected. All inpatient and outpatient costs in a 1-year period postsurgery including the index surgical procedure were collected via the hospital administrative cost database (normalized to 2014). RESULTS: A total of 147 cases were identified (94 TBW, 53 PF). PF was associated with higher mean age (P < .01), higher American Society of Anesthesiologists score (P < .01), and higher proportion of hypertensives (P = .04). There was no difference in the range of motion achieved at 1 year for both groups. In terms of complications, TBW was associated with more symptomatic hardware (21.6% vs. 13.7%, P = .24) and implant failures (16.5% vs. none, P < .01), whereas the plate group had a higher wound complication (5.9% vs. none, P = .02) and infection rate (9.8% vs. 3.1%, P = .09). TBW had a higher implant removal rate of 30.9% compared with 22.7% for PF (P = .36). PF had a higher cost at all time points, from the index surgery ($10,313.64 vs. $5896.36, P < .01), 1-year cost excluding index surgery ($5069.61 vs. $3850.46, P = .46), and outpatient cost ($1667.80 vs. $1613.49, P = .27). DISCUSSION AND CONCLUSION: Based on our study results, we have demonstrated that TBW is the ideal implant for Mayo 2A olecranon fractures from both a clinical and economic standpoint, with comparable clinical results, potentially similar implant removal rates as PF's, and a lower cost over a 1-year period. In choosing the ideal implant, the surgeon must take into account, first, the local TBW and PF removal rate, which can vary significantly because of the patient's profile and beliefs, and second, the PF implant cost.

Assessment of Anatomic Restoration of Distal Radius Fractures Among Older Adults: A Secondary Analysis of a Randomized Clinical Trial.

Importance: The value of precise anatomic restoration for distal radius fractures (DRFs) in older adults has been debated for many decades, with conflicting results in the literature. In light of the growing population of adults aged 60 years and older, both fracture incidence and associated treatment costs are expected to increase. Objective: To determine the association between radiographic measures of reduction and patient outcomes after DRF in older patients. Design, Setting, and Participants: Data were collected from the Wrist and Radius Injury Surgical Trial (WRIST), a multicenter randomized clinical trial of DRF treatments for adults aged 60 years and older (enrollment from April 10, 2012, to December 31, 2016, with a 2-year follow-up). Data analysis was performed from January 3, 2019, to August 19, 2019. WRIST participants who completed 12-month assessments were included in the study. According to the biomechanical principle of alignment, 2-phase multivariable regression models were adopted to assess the association between radiographic measures of reduction and functional and patient-reported outcomes 12 months following treatment. Interventions: Participants were randomized to receive volar locking plate, percutaneous pinning, or external fixation. Those who opted for nonoperative treatment received casts. Main Outcomes and Measures: Hand grip strength, wrist arc of motion, radial deviation, ulnar deviation, the Michigan Hand Outcomes Questionnaire (MHQ) total score, MHQ function score, and MHQ activities of daily living score were measured at 12 months following treatment. Results: Data from 166 WRIST participants (144 [86.7%] women; mean [SD] age, 70.9 [8.9] years) found that only 2 of the 84 correlation coefficients calculated were statistically significant. For patients aged 70 years or older, every degree increase in radial inclination away from normal (22°) grip strength in the injured hand was 1.1 kg weaker than the uninjured hand (95% CI, 0.38-1.76; P = .004) and each millimeter increase toward normal (0 mm) in ulnar variance was associated with a 10.4-point improvement in MHQ ADL score (95% CI, -16.84 to -3.86; P = .003). However, neither of these radiographic parameters appeared to be associated with MHQ total or function scores. Conclusions and Relevance: The study results suggest that precise restoration of wrist anatomy is not associated with better patient outcomes for older adults with DRF 12 months following treatment. Surgeons can consider this evidence to improve quality of care by prioritizing patient preferences and efficient use of resources over achieving exact realignment.

Variation in Implant Selection for Ankle Fractures: Identifying Cost Drivers.

BACKGROUND: Implant selection is the first opportunity for surgeons to control costs of fracture fixation. The current literature has demonstrated surgeons' poor understanding of implant costs. Our study evaluated implant cost variability for surgically treated ankle fractures and distal tibia fractures. Our hypothesis was that significant cost variation exists among providers. The goal was to identify cost drivers and determine whether specialty training is linked to implant selection. METHODS: A retrospective 2010-2017 chart review was performed for 1281 patients at a Level I trauma center. Patients were excluded for skeletal immaturity, open fractures, polytrauma, and concurrent surgeries. Variables were assessed included age, sex, body mass index, OTA/AO classification, Weber classification, 1-year reoperation status, surgeon specialty, and use of syndesmotic screws, locking plates, and cannulated screws. Construct cost was determined by using electronic medical record implant model numbers cross-referenced with the chargemaster database. Statistical analysis involved intergroup comparative tests, regression analysis, and goodness-of-fit analyses. RESULTS: Implant cost was different among OTA patterns (P < 0.01), highest among 43C ($3771) and lowest with 44A ($819). Construct costs of OTA 43 fractures varied from $2568 to 3771, whereas OTA 44 ranged from $819 to $1474. Costs were comparable across Weber patterns (P = 0.15), with Weber B having the highest ($1494). Costs were highest among reconstructive, podiatry, and spine surgeons, with mean costs of $1804, $1404, and $1396, respectively. Traumatologist constructs had the lowest overall price ($987). A total of 433 (33.8%) procedures used locking plates with 512 (40.0%) using at least one cannulated screw. Locking plates averaged a larger total implant cost ($1947) than nonlocking plates ($1313) but had a comparable reoperation rate (18.5% vs. 17.7%, P = 0.81). Use of a cannulated screw presented a higher total cost ($2008 vs. $1435) with comparable reoperation rates (17.4% vs. 18.8%, P = 0.72). A total of 401 (31.5%) patients received syndesmotic fixation and a significantly higher reoperation rate (17.0% vs. 11.0%, P < 0.01). Overall, 199 patients underwent elective hardware removal, 23 were infected, 7 required revision, and 3 were identified with a nonunion. CONCLUSIONS: Our study demonstrated significant variability in implant costs for ankle fracture fixation and identified the key cost drivers as locking plates and cannulated screws. Surgical management of ankle fractures could be an ideal setting to pilot economic alignment between physicians and hospitals to drive value. LEVEL OF EVIDENCE: Level III. Retrospective Cohort.

Does an Implant Usage Report Card Impact Orthopaedic Trauma Implant Stewardship?

OBJECTIVES: As hospitals seek to control variable expenses, orthopaedic surgeons have come under scrutiny because of relatively high implant costs. We aimed to determine whether feedback to surgeons regarding implant costs results in changes in implant selection. METHODS: This study was undertaken at a statewide trauma referral center and included 6 fellowship-trained orthopaedic trauma surgeons. A previously implemented implant stewardship program at our institution using a "red-yellow-green" (RYG) implant selection tool classifies 7 commonly used trauma implant constructs based on cost and categorizes each implant as red (used for patient-specific requirements, most expensive), yellow (midrange), and green (preferred vendor, least expensive). The constructs included were femoral intramedullary nail, tibial intramedullary nail, long and short cephalomedullary nails, distal femoral plate, proximal tibial plate, and lower-limb external fixator. Baseline implant usage from the previous year was obtained and provided to each surgeon. Each surgeon received a monthly feedback report containing individual implant utilization and overall ranking. RESULTS: The overall RYG score increased from 68.7 to 79.1 of 100 (P < 0.001). Three of the 7 implants (tibial and femoral nails and lower-limb external fixation) had significant increases in their RYG scores; implant selections for the other 4 implants were not significantly altered. A decrease of 1.8% (95% confidence interval, 0.4-3.2, P = 0.01) was noted in overall implant costs over the study period. CONCLUSION: Our intervention resulted in changes in surgeons' implant selections and cost savings. However, surgeons were unwilling to change certain implants despite their being more expensive.

The importance of costing perspective: an example evaluating the cost-effectiveness of a locking versus nonlocking plate in medial opening wedge high tibial osteotomy

Summary: High tibial osteotomy (HTO) fixation can be achieved using various plate designs. Compared with nonlocking plates, the stability of locking plates allows patients to return to weight-bearing and work sooner and may also decrease postoperative complications, introducing the potential for overall cost savings. However, material costs for locking plates are higher, and the plate bulkiness may lead to additional surgery to remove the plate. We conducted a retrospective study to evaluate the cost-effectiveness of a locking versus a nonlocking plate in HTO from both the health care payer and societal perspectives up to 12 months postoperative. We observed that from a health care payer perspective, the locking plate was not cost-effective. However, the locking plate was cost-effective from the societal perspective (addition of indirect costs, such as time off work). These findings highlight the importance of considering costing perspective in economic evaluations for chronic conditions, particularly in publicly funded health care systems.

Tension band wiring versus locking plate fixation for simple, two-part Mayo 2A olecranon fractures: a comparison of post-operative outcomes, complications, reoperations and economics.

PURPOSE: Simple displaced transverse olecranon fractures are traditionally managed operatively with a tension band wire device (TBW). We compared clinical outcomes, morbidity and the cost of treatment of TBW versus pre-countered low-profile locking plates for the treatment of Mayo 2A fractures. PATIENT AND METHODS: All olecranon fractures admitted to our unit between 2008 and 2014 were identified (n = 129). Patient notes and radiographs were studied from presentation to final follow-up. Patient outcomes were recorded using the QuickDASH (Disabilities of Arm, Shoulder and Hand) score. Patient demographics and nature of complications were recorded as were the rate and nature of any repeat operation. RESULTS: Eighty-nine patients had Mayo 2A fractures (69%). Sixty-four underwent TBW (n = 48) or locking plate fixation (n = 16). The mean ages of both groups were similar at 57 (15-93) and 60 (22-80), respectively. In the TBW group, the mean post-injury QuickDASH was 12.9, compared with 15.0 for the locking plate group. There was no statistically significant difference between the outcomes for either group. Nineteen of the 48 TBW patients had complications (39.6%). Sixteen of the 48 TBW patients had reoperations (33.3%). In particular, we would highlight that 13 (27.1%) of patients treated with TBW underwent subsequent removal of metalwork for hardware irritation. There were no complications and or reoperations in the 16 patients who received locking plate fixation. Both complication and reoperation rates were statistically significantly different. Despite being initially more expensive, when the cost of reoperation for TBW group was included, locking plates were found to be on average £236.33 less per patient than for TBW. CONCLUSIONS: We suggest that locking plates are superior to TBW concerning post-operative morbidity, reoperation rate and cost for Mayo 2A fractures in contrast to previous articles. LEVEL OF EVIDENCE: Therapeutic study, III.

Evaluation of Factors Driving Cost Variation for Distal Radius Fracture Open Reduction Internal Fixation.

PURPOSE: Distal radius fracture open reduction and internal fixation (ORIF) represents a considerable cost burden to the health care system. We aimed to elucidate demographic-, injury-, and treatment-specific factors influencing surgical encounter costs for distal radius ORIF. METHODS: We retrospectively reviewed adult patients treated with isolated distal radius ORIF between November 2014 and October 2016 at a single tertiary academic medical center. Using our institution's information technology value tools-which allow for comprehensive payment and cost data collection and analysis on an item-level basis-we determined relative costs (RC) for each factor potentially influencing total direct costs (TDC) for distal radius ORIF using univariate and multivariable gamma regression analyses. RESULTS: Of the included 108 patients, implants and facility utilization costs were responsible for 48.3% and 37.9% of TDC, respectively. Factors associated with increased TDC include plate manufacturer (RC 1.52 for the most vs least expensive manufacturer), number of screws (RC 1.03 per screw) and distal radius plates used (RC 1.67 per additional plate), surgery setting (RC 1.32 for main hospital vs ambulatory surgery center), treating service (RC 1.40 for trauma vs hand surgeons), and surgical time (RC 1.04 for every 10 min of additional surgical time). Open fracture was associated with increased costs (RC 1.55 vs closed fracture), whereas other estimates of fracture severity were nonsignificant. In the multivariable model controlling for injury-specific factors, variables including implant manufacturer, and number of distal radius plates and screws used, remained as significant drivers of TDC. CONCLUSIONS: Substantial variations in surgical direct costs for distal radius ORIF exist, and implant choice is the predominant driver. Cost reductions may be expected through judicious use of additional plates and screws, if hospital systems use bargaining power to reduce implant costs, and by efficiently completing surgeries. CLINICAL RELEVANCE: This study identifies modifiable factors that may lead to cost reduction for distal radius ORIF.

On-Site 3-Dimensional Printing and Preoperative Adaptation Decrease Operative Time for Mandibular Fracture Repair.

PURPOSE: The purpose of this study was to compare the intraoperative time and operating room costs between patients with mandibular fractures treated with traditional adaptation and fixation and patients treated with preadapted plates created with on-site 3-dimensionally printed models. PATIENTS AND METHODS: We designed a prospective comparative cohort study for patients with mandibular fractures. The control group received traditional open reduction and internal fixation of their mandibular fractures. For the patients in the experimental group, a 3-dimensional (3D) model of the fractured mandible was made using an on-site 3D printer. The model then underwent osteotomy, if needed, and the plate was adapted to the model, submitted to sterilization, and implanted in the patient. The primary outcome variable was intraoperative plating time, and the secondary outcome variable was operating room cost. The groups were compared by the Wilcoxon signed rank test. RESULTS: The 38 patients included in the study had a mean age of 39.6 years, and male patients comprised 81.6%. The mean time for intraoperative plate adaptation was 22.8 ± 2.1 minutes in the control group and 6.9 ± 0.3 minutes in the experimental, 3D printed group (P < .0001). In the experimental group, 4 patients (21%) required a single intraoperative corrective bend. The calculated average cost per patient based on the average operating costs at our institution was $2,306.45 in the control group and $698.00 in the experimental group. CONCLUSIONS: This study shows that the use of 3D printers for fabrication of models to prebend maxillofacial reconstruction plates is associated with decreased operating room time and costs. Using an on-site 3D printer requires minor start-up and use costs and results in a significant reduction in operating room time, which remains one of the most expensive aspects of facial trauma care.

Reconstruction Plate-Based Antibiotic Cement Spacers: Clinical Outcomes and Description of Technique.

The standard of care for chronic deep peri-prosthetic hip infection is a two-stage exchange with placement of a temporary antibiotic cement spacer and treatment with intravenous antibiotics. Several commercially available cement spacer options exist. We report on a novel antibiotic spacer that may be an efficient, cost-effective alternative. Medical records of all patients treated for deep peri-prosthetic hip infection after total hip arthroplasty between 2004 and 2012 were reviewed. Each antibiotic spacer was constructed from a 12- to 16-hole recon plate bent to provide adequate soft tissue tension and a cement ball that matched the acetabulum. Premature failure of the plate and duration of implantation were measured. Failure was defined as fracture of the plate or dissociation of the cement head from the plate. Costs were compared with commercially available cement spacers. A total of 24 spacers were identified in 21 patients (mean age 68.9 years, mean body-mass index 26.4). The mean time between spacer placement and re-implantation was 6.4 months (range: 1.8-18 months). One patient had an indolent infection that was unresponsive to antibiotic therapy and required a hip disarticulation. At the time of reimplantation, 17 of 17 handmade spacers had no failures. Of the premade spacers, six of the seven had no failures. One premade spacer fractured at the femoral component trunion. The cost of the plate and antibiotic cement was $909-1000, approximately $5000 less than premade spacers. Antibiotic spacers can be readily constructed intraoperatively and offer good clinical outcomes with a low incidence of failure. This type of spacer saved $5000 per patient.

Locking Plate Fixation in a Series of Bicondylar Tibial Plateau Fractures Raises Treatment Costs Without Clinical Benefit.

OBJECTIVES: To compare outcomes and costs between locking and nonlocking (NL) constructs in the treatment of bicondylar tibial plateau (BTP) fractures. DESIGN: Retrospective cohort study. SETTING: Level 1 academic trauma center. PATIENTS: All patients who presented with complete articular, BTP fractures OTA/AO 41-C and Schatzker VI between 2013 and 2015 were screened (n = 112). Patients treated with a mode of fixation other than plate-and-screw were excluded. Fifty-six patients with a minimum follow-up of 12 months were included in the analysis. INTERVENTION: Operative fixation of BTP fractures with locking (n = 29) or NL (n = 27) implants. MAIN OUTCOME MEASUREMENTS: Implant cost, patient-reported outcomes (PROMIS physical function and pain interference), clinical, and radiographic outcomes. RESULTS: There were no differences between the 2 groups with respect to demographics, injury characteristics, radiographic outcomes (change in alignment), or clinical outcomes (PROMIS, reoperation, nonunion, and infection). Implant costs were significantly greater in the locking group compared with the NL group (mean L, $4453; mean NL, $2569; P < 0.01). CONCLUSIONS: This study demonstrated improved value of treatment (less cost with no difference in clinical outcome) with NL implants for BTP fractures when dual-plate fixation strategies are performed. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Comparison of Locking Versus Nonlocking Plates for Distal Fibula Fractures.

Locking plates might offer a biomechanical fixation advantage for distal fibula fractures with comminution or osteoporotic bone. In January 2011, our unit introduced a bone-specific locking plate for the distal fibula. The aim of the present study was to compare it against more conventional plating system implants for lateral malleolar fixation in terms of outcomes, crude costs, and complications. We retrospectively reviewed a consecutive cohort of patients with closed ankle fractures who presented within a 24-month period. The clinical and radiographic outcomes were compared among conventional plating using a one-third semitubular plate, a 3.5-mm limited-contact dynamic compression plate, and a 2.7-mm/3.5-mm locking compression distal fibula plate. A total of 145 patients with ankle fractures underwent surgical fixation: 87 (60.0%) with the semitubular plate, 22 (15.2%) with the limited-contact dynamic compression plate, and 36 (24.8%) with the locking compression distal fibula plate. A greater proportion of patients with established osteoporosis or osteoporosis risk factors were in the locking compression distal fibula plate group (27.8% versus 2.3% and 0%). Four patients (2.8%) required washout for infection. No significant differences were found between the sex distribution within the 3 groups (p = .432). No significant difference was found in the complication rate (p = .914) or the reoperation rate (p = .291) among the 3 groups. Although costing >6 times more than a standard fibula fixation construct (implant cost), bone-specific locking compression distal fibula plates add to the portfolio of implants available, especially for unstable fractures with poor bone quality.

Economic Analysis of Anatomic Plating Versus Tubular Plating for the Treatment of Fibula Fractures.

Ankle fractures are among the most common injuries requiring operative management. Implant choices include one-third tubular plates and anatomically precontoured plates. Although cadaveric studies have not revealed biomechanical differences between various plate constructs, there are substantial cost differences. This study sought to characterize the economic implications of implant choice. A retrospective review was undertaken of 201 consecutive patients with operatively treated OTA type 44B and 44C ankles. A Nationwide Inpatient Sample query was performed to estimate the incidence of ankle fractures requiring fibular plating, and a Monte Carlo simulation was conducted with the estimated at-risk US population for associated plate-specific costs. The authors estimated an annual incidence of operatively treated ankle fractures in the United States of 59,029. The average cost was $90.86 (95% confidence interval, $90.84-$90.87) for a one-third tubular plate vs $746.97 (95% confidence interval, $746.55-$747.39) for an anatomic plate. Across the United States, use of only one-third tubular plating over anatomic plating would result in statistically significant savings of $38,729,517 (95% confidence interval, $38,704,773-$38,754,261; P<.0001). General use of one-third tubular plating instead of anatomic plating whenever possible for fibula fractures could result in cost savings of up to nearly $40 million annually in the United States. Unless clinically justifiable on a per-case basis, or until the advent of studies showing substantial clinical benefit, there currently is no reason for the increased expense from widespread use of anatomic plating for fractures amenable to one-third tubular plating.

Comparison of Surgical Outcomes, Narcotics Utilization, and Costs After an Anterior Cervical Discectomy and Fusion: Stand-alone Cage Versus Anterior Plating.

STUDY DESIGN: Retrospective cohort analysis of a prospectively maintained registry. OBJECTIVE: To compare the surgical outcomes, narcotic utilization, and costs between a stand-alone (SA) cage and anterior plating (AP) with an interbody device for 1-level anterior cervical discectomy and fusion (ACDF). BACKGROUND DATA: ACDF with a SA cage has gained popularity as a potential alternative to anterior cervical plating. Few studies have compared the surgical outcomes, narcotic utilization, and costs of ACDF utilizing a SA cage versus AP with an interbody device. METHODS: Patients who underwent a primary 1-level ACDF for degenerative spinal pathology between 2010 and 2013 were analyzed. Patients were stratified on the basis of the type of implant system (SA cage vs. AP) and assessed with regard to demographics, comorbidities, smoking, visual analogue scale (VAS) scores (preoperative/postoperative), procedural time, estimated blood loss (EBL), length of hospitalization, complications, reoperations, narcotic consumption, and total costs. Statistical analysis was performed with independent sample T tests for continuous variables and χ analysis for categorical data. An α level of <0.05 denoted statistical significance. RESULTS: Of the 93 patients included, 52 (55.9%) underwent an ACDF with a SA cage system. Patient demographics, comorbidity burden, body mass index, smoking status, and preoperative VAS score were similar between cohorts. The SA cohort incurred a significantly lower EBL (P<0.001) than the AP cohort. However, none required a transfusion and the procedural time, length of hospitalization, postoperative VAS score, complication rates, 1-year arthrodesis rate, and reoperation rates were similar between cohorts. Postoperative narcotics consumption and total costs were also similar between groups. CONCLUSIONS: Our findings suggest that the SA cage may be associated with a significantly lower EBL, which may not be clinically relevant. Perioperative outcomes, complications, reoperation rates, narcotics consumption in the immediate postoperative period, and total costs may be similar regardless of the instrumentation utilized in a 1-level ACDF.

Implant Failure Rates and Cost Analysis of Contoured Locking Versus Conventional Plate Fixation of Distal Fibula Fractures.

The authors analyzed 330 consecutive Weber B distal fibula fractures that occurred during a 3-year period and were treated with either a contoured locking plate or a conventional one-third tubular plate to compare the cost and failure rates of the 2 constructs. The primary outcomes were failure of the distal fibular implant and loss of reduction. Secondary outcomes were surgical wound infection requiring surgical debridement and/or removal of the fibular implant, and removal of the fibular plate for persistent implant-related symptoms. No failure of the fibular plates or distal fibular fixation occurred in either group. A total of 5 patients required surgical revision of syndesmotic fixation within 4 weeks of the index surgery. Of these patients, 1 was in the contoured locking plate group and 4 were in the one-third tubular plate group (P=.610). The rate of deep infection requiring surgical debridement and/or implant removal was 6.2% in the contoured locking plate group and 1.4% in the one-third tubular plate group (P=.017). The rate of lateral implant removal for either infection or symptomatic implant was 9.3% in the contoured locking plate group and 2.3% in the one-third tubular plate group (P=.005). A typical contoured locking plate construct costs $800 more than a comparable one-third tubular plate construct. Based on a calculated estimate of 60,000 locking plates used annually in the United States, this difference translates to a potential avoided annual cost of $50 million nationally. This study demonstrates that it is possible to treat Weber B distal fibula fractures with one-third tubular plates at a substantially lower cost than that of contoured locking plates without increasing complications.
