    ABSTRACT: Modifier 22 in the American Medical Association's Current Procedural Terminology (CPT(®)) book is a billing code for professional fees used to reflect an increased amount of skill, time, and work required to complete a procedure. There is little disagreement that using this code in the setting of surgery for acetabulum fractures in the obese patient is appropriate; however, to our knowledge, the degree to which payers value this additional level of complexity has not been determined. We asked whether (1) the use of Modifier 22 increased reimbursements in morbidly obese patients and (2) there was any difference between private insurance and governmental payer sources in treatment of Modifier 22. Over a 4-year period, we requested immediate adjudication with payers when using Modifier 22 for morbidly obese patients with acetabular fractures. We provided payers with evidence of the increased time and effort required in treating this population. Reimbursements were calculated for morbidly obese and nonmorbidly obese patients. Of the 346 patients we reviewed, 57 had additional CPT(®) codes or modifiers appended to their charges and were excluded, leaving 289 patients. Thirty (10%) were morbidly obese and were billed with Modifier 22. Fifty-three (18%) were insured by our largest private insurer and 69 (24%) by governmental programs (Medicare/Medicaid). Eight privately insured patients (15%) and seven governmentally insured patients (10%) were morbidly obese and were billed with Modifier 22. For our primary question, we compared reimbursement rates between patients with and without Modifier 22 for obesity within the 289 patients. We then performed the same comparison for the 53 privately insured patients and the 69 governmentally insured patients. Overall, there was no change in mean reimbursement when using Modifier 22 in morbidly obese patients, compared to nonmorbidly obese patients (USD 2126 versus USD 2149, p < 0.94). There was also no difference in mean reimbursements with Modifier 22 in either the privately insured patients (USD 3445 versus USD 2929, p = 0.16) or the governmentally insured patients (USD 1367 versus USD 1224, p = 0.83). Despite educating payers on the increased complexity and time needed to deal with morbidly obese patients with acetabular fractures, we have not seen an increased reimbursement in this challenging patient population. This could be a disincentive for many centers to treat these challenging injuries. Further efforts are needed to convince government payer sources to increase compensation in these situations.

    ABSTRACT: To report the impact of computerized tomography (CT) based radiotherapy (RT) on heterotopic ossification (HO) outcomes. This is a single institution, retrospective study of 532 patients who were treated for traumatic acetabular fractures (TAF). All patients underwent open-reduction internal-fixation (ORIF) of the TAF followed by RT for HO prophylaxis. Postoperative RT was delivered within 72hours, in a single fraction of 7Gy. The patients were divided into 2 groups based on RT planning: CT (A) vs. clinical setup (B). At a median follow up of 8years the incidence of HO was 21.6%. Multivariate regression analysis revealed that group (A) vs. (B) had HO incidence of 6.6% vs. 24.6% (p<0.001), respectively. Furthermore, HO Brooker grade ≥3 was observed in 2.2% vs. 10.8% (P=0.007) in group (A) vs. (B), respectively. Thus, the odds of developing HO and Brooker grades ≥3 were are 4.7 and 4.5 times higher, respectively, in patients who underwent clinical setup. Our data suggest that using CT based RT allowed more accurate delineation of the tissues and better clinical outcomes. Although CT-based RT is associated with additional cost the efficacy of CT-based RT reduces the risk of HO, thereby decreasing the need for additional surgical interventions.

    ABSTRACT: We describe the preliminary findings of seatbelt compliance among severely injured blunt trauma patients involved in motor vehicle crashes in Mississippi. Stratification of the sample size of 1,405 patients included obese versus the non-obese patients with sub-stratification of weight classes to include normal weight, overweight, obese and morbidly obese. An overview of the design of the study is included. The results demonstrate no significant difference between the numbers of restrained and unrestrained obese patients compared to their normal weight counterparts. Our findings suggest unrestrained patients regardless of weight class had higher ISS than restrained individuals. The data for Mississippi is similar to those reported nationally. Interestingly, we observed the injury severity scores in the restrained obese and morbidly obese patients were higher than the unrestrained motorists within the same weight cohort. This may reflect less movement within the vehicle resulting in less trauma.

    ABSTRACT: Pregnancy is associated with maternal bone mineral density loss and modulation of calcium metabolism. We hypothesized that pregnancy may decrease the risk of heterotopic ossification (HO) after trauma. This is a single-institution, University of Mississippi Medical Center, retrospective study investigating the effect of pregnancy on the incidence HO after surgical repair (SR) of displaced acetabular fractures. Between January 1998 and 2010, 257 non-pregnant women (Group A) and 16 pregnant women (Group B) were identified. All the non-pregnant women received radiation therapy (RT) ± indomethacin. None of the pregnant women in group B received any prophylaxis. After a median follow-up of 6.6 years the incidence of HO in all patients was 27% (75/273). In Group A, non-pregnant, women who received RT ± indomethacin, 29% developed HO; HO risk was 0.4. In Group B, 16 pregnant patients, only one developed HO (6%); HO risk was 0.06. Thus, the risk of HO appears to be nearly six-fold higher in non-pregnant women despite prophylactic RT ± indomethacin. Our data suggest that pregnancy may be associated with a reduced risk of HO after SR of displaced acetabular fractures. Further analysis with a larger pregnant patient sample is necessary to confirm this finding. © 2013 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res.

    ABSTRACT: Increasing attention is being paid to the influences that the body habitus and weight of the pediatric patient impose upon the fixation methods for femur fractures. Of the widely accepted treatment options, little biomechanical or clinical data exist comparing flexible intramedullary nailing and locked plating. The aim of this study was to compare the mechanical stability of unstable pediatric diaphyseal femur fractures fixed with titanium flexible intramedullary nails or a titanium locking plate using a synthetic femur model. Fracture stabilization was carried out with either 4.0-mm titanium elastic nails or 16-hole 4.5-mm narrow titanium locking compression plates. Axial and rotational testing of each specimen was performed. The axial loading rate was 0.20 mm/s. The torsional loading rate was 0.1 degrees rotation per second. The axial compressive modulus was defined as the compressive stress divided by the compressive strain. The rotational stiffness was defined as the torque moment applied to the femoral head divided by the resulting rotational displacement (in radians). The yield point or load to failure of the simulated fracture constructs was recorded for each specimen. The modulus for comminuted fractures measured during the application of axial compression was 0.657 GPa for plate constructs and 0.326 GPa for elastic nail constructs (P=0.021). The modulus for oblique fractures during axial loading treated with plate fixation or titanium elastic nails was 1.63 and 0.466 GPa, respectively (P<0.0001). The yield point for comminuted fractures occurred at an axial load of 2304.7 N (SD ± 315.77) for plate constructs and 383.6 N (SD ± 139.2) for elastic nail constructs (P<0.001). For oblique fractures, the yield load occurred at 3111.9 N (SD ± 821.9) for plate constructs and at 1367.0 N (SD ± 98.9) for elastic nail constructs (P<0.0001). Locked plating provides a biomechanically more stable construct than elastic intramedullary nailing. Its use as part of the technique of indirect reduction and submuscular plating remain a viable alternative in the treatment of length-unstable pediatric femur fracture patterns. : Provide biomechanical evidence supporting the use of plating techniques in the pediatric femur fracture population.

    ABSTRACT: To ascertain whether the time from injury to prophylactic radiation therapy (RT) influences the rate of heterotopic ossification (HO) after operative treatment of displaced acetabular fractures. This is a single-institution, retrospective analysis of patients referred for RT for the prevention of HO. Between January 2000 and January 2009, 585 patients with displaced acetabular fractures were treated surgically followed by RT for HO prevention. We analyzed the effect of time from injury on prevention of HO by RT. In all patients, 700 cGy was prescribed in a single fraction and delivered within 72 hours postsurgery. The patients were stratified into five groups according to time interval (in days) from the date of their accident to the date of RT: Groups A ≤3, B ≤7, C ≤14, D ≤21, and E >21 days. Of the 585 patients with displaced acetabular fractures treated with RT, (18%) 106 patients developed HO within the irradiated field. The risk of HO after RT increased from 10% for RT delivered ≤3 days to 92% for treatment delivered >21 days after the initial injury. Wilcoxon test showed a significant correlation between the risk of HO and the length of time from injury to RT (p < 0.0001). Chi-square test and multiple logistic regression analysis showed no significant association between all other factors and the risk of HO (race, gender, cause and type of fracture, surgical approach, or the use of indomethacin). Our data suggest that there is higher incidence and risk of HO if prophylactic RT is significantly delayed after a displaced acetabular fracture. Thus, RT should be administered as early as clinically possible after the trauma. Patients undergoing RT >3 weeks from their displaced acetabular fracture should be informed of the higher risk (>90%) of developing HO despite prophylaxis.

    ABSTRACT: To analyze the impact of different body mass index (BMI) as a surrogate marker for heterotopic ossification (HO) in patients who underwent surgical repair (SR) for displaced acetabular fractures (DAF) followed by radiation therapy (RT). This is a single-institution retrospective study of 395 patients. All patients underwent SR for DAF followed by RT ± indomethacin. All patients received postoperative RT, 7 Gy, within 72 h. The patients were separated into four groups based on their BMI: <18.5, 18.5-24.9, 25-29.9, and >30. The end point of this study was to evaluate the efficacy of RT ± indomethacin in preventing HO in patients with different BMI. Analysis of BMI showed an increasing incidence of HO with increasing BMI: <18.5, (0%) 0/6 patients; 18.5-24.9 (6%), 6 of 105 patients developed HO; 25-29.9 (19%), 22 of 117; >30 (31%), 51 of 167. Chi-square and multivariate logistic regression analysis showed that the correlation between odds of HO and BMI is significant, p < 0.0001. As the BMI increased, the risk of HO and Brooker Classes 3, 4 HO increased. The risk of developing HO is 1.0× (10%) more likely among those with higher BMI compared with those with lower BMI. For a one-unit increase in BMI the log odds of HO increases by 1.0, 95% CI (1.06-1.14). Chi-square test shows no significant difference among all other factors and HO (e.g., indomethacin, race, gender). Despite similar surgical treatment and prophylactic measures (RT ± indomethacin), the risk of HO appears to significantly increase in patients with higher BMI after DAF. Higher single-fraction doses or multiple fractions and/or combination therapy with nonsteroidal inflammatory drugs may be of greater benefit to these patients.

    ABSTRACT: We have shown that obese Zucker rats with orthopedic trauma (OZT) exhibit a loss of arteriolar tone in skeletal muscle. We hypothesize that the loss of arteriolar tone in OZT blunts vasoconstrictor responses to hemorrhage, resulting in an impaired blood pressure recovery. Orthopedic trauma was induced with soft tissue injury and local injection of bone components in both hindlimbs in lean (LZT) and OZT (11-13 wk). One day after the orthopedic trauma, blood pressure responses following hemorrhage were measured in conscious control lean, control obese, LZT, and OZT. In another set of experiments, the spinotrapezius muscle of control and trauma animals was prepared for microcirculatory observation. Arteriolar responses to phenylephrine (PE) or hemorrhage were determined. Hemorrhage resulted in similar blood pressure responses in control animals and LZT, but the blood pressure recovery following hemorrhage was blunted in the OZT. In the spinotrapezius, OZT exhibited decreased arteriolar tone and blunted vasoconstrictor responses to PE and hemorrhage. Treatment with glibenclamide improved the blood pressure recovery in the conscious OZT and improved the arteriolar tone, and PE induced vasoconstriction in the spinotrapezius of the OZT. Thus, ATP-dependent K(+) channel-mediated loss of arteriolar tone in OZT blunts the arteriolar constriction to hemorrhage, resulting in impaired blood pressure recovery.

    ABSTRACT: To evaluate the radiographic and computed tomographic reduction qualities after acetabular fracture repair in obese and nonobese patients. Retrospective review. University medical center. Two hundred forty-two patients were treated with open reduction internal fixation for displaced acetabular fractures. The nonobese group (Group 1) consisted of 149 patients and the obese group (Group 2) had 93 patients. A nonmorbidly obese group (Group 3 = 221 patients) and a morbidly obese group (Group 4 = 21 patients) were also created from the same patient population. Operative repair of acetabular fractures. Reductions on postoperative radiographs were classified as anatomic with less than 1 mm, imperfect with 2 to 3 mm, and poor with greater than 3 mm of residual displacement. On postoperative computed tomographic scans, reductions were considered nonanatomic with persistent gap or step displacements greater than or equal to 2 mm. Anatomic radiographic reductions were achieved in 72% of the nonobese patients, 70% of the obese patients, 72% of the nonmorbidly obese patients, and 61% of the morbidly obese patients. (P = 0.379) On postoperative computed tomographic scans, an acceptable reduction was obtained in 47% of the nonobese patients, 44% of the obese patients, 47% of the nonmorbidly obese patients, and 31% of the morbidly obese patients. (P = 0.232). Anatomic or satisfactory reductions can be similarly achieved in all classes of nonmorbidly obese patients who have sustained displaced acetabular fractures. In the morbidly obese, anatomic reductions may be more difficult to obtain.

    ABSTRACT: To evaluate the validity of using lateral intraoperative fluoroscopic imaging to assess the reduction of the tibial plafond articular surface, two hypotheses were tested: 1) the distal tibial subchondral shadow on the lateral ankle radiograph is created equally by the medial, central, and lateral portions of the distal tibia; and (2) displacement of a 5-mm width osteochondral fragment is consistently recognizable on lateral fluoroscopic imaging. Six human fresh-frozen tibial plafond cadaveric specimens were sagitally sectioned in 5-mm increments after removal of the anterior soft tissue and stabilization of the position of the ankle through external fixation. To test the first hypothesis, a perfect lateral radiograph was taken after sectioning the specimens. The sagittal sections were then removed sequentially from medial to lateral. A perfect lateral radiograph was taken after each change. The sagittal sections were then removed beginning laterally and moving medially. A perfect lateral radiograph was taken after each change. The images were then compared with specific evaluation of the change in the subchondral shadow density. To test the second hypothesis, three malreductions were created by displacing a 5-mm osteochondral segment. After each malreduction, a perfect lateral radiograph was saved. These saved fluoroscopic images were placed in random order with lateral images of normal specimens. Four experienced ankle surgeons were then asked to determine whether the radiographs revealed displacement. Inter- and intraobserver reliability was then evaluated. First, the subchondral shadow of the distal tibia appears to be created by an equal confluence of the subchondral bone of the medial, central, and lateral aspects of the tibial plafond. Second, fellowship-trained observers experienced in pilon fracture treatment correctly identified malreduction only 45% of the time. Intraclass correlation coefficient revealed very poor interobserver reliability with an alpha reliability statistic of 0.183. Intraobserver reliability across all four observers yielded an alpha statistic of 0.474, indicating inconsistencies in observers' evaluation of identical images at separate viewings. It is difficult to discern rotational or translational displacement of a 5-mm osteochondral fragment on a perfect lateral fluoroscopic view of the ankle. Even with what appears to be a perfect lateral fluoroscopic view intraoperatively, displacement may still be present. When small osteochondral fragments are present, direct visualization of the articular surface is necessary to confidently establish that an anatomic reduction has been achieved.

    ABSTRACT: The open operative management of pelvic and acetabular fractures in the obese is technically demanding, with a significantly higher rate of complications compared with patients who are nonobese. The decision to perform surgery should involve a thorough understanding of risks, and patients should be counseled. Careful attention should be paid to patient factors; coexisting systemic conditions and patient positioning to reduce complications. Wound complications are most commonly seen, and techniques to reduce risk should be incorporated. When complications occur, aggressive management can result in successful salvage. Future areas of study should include methods to reduce risk of surgical site infections and improving our understanding of the physiologic alterations that occur with obesity. This article summarizes the current literature on open treatment of pelvic and acetabular fractures in the obese patient, reviews the physiologic adaptations of obesity as they relate to pelvic surgery, highlights risk factors for complications, and provides recommendations to reduce the incidence of complications.

    ABSTRACT: The obesity epidemic continues to grow. As the number of obese people increases, it is logical to expect an increasing number of obese patients and increasing costs to care for these patients. Orthopedic surgeons will see many of these patients who need treatment for injuries and chronic conditions. Care of obese patients requires more work and time in providing nonoperative and operative care. No system has been proposed to handle reimbursement disparities, particularly for providers. The model for health care will change and, along with it, should be all parties coming together to address inequalities and inequities in care for obese and morbidly obese patients.

    ABSTRACT: Obese subjects with orthopedic trauma exhibit increased inflammation and an increased risk of pulmonary edema. Prostaglandin E(2) (PGE(2) ) production is elevated during inflammation and associated with increased vascular permeability. We hypothesize that pulmonary edema in obesity following orthopedic trauma is due to elevated PGE(2) and resultant increases in pulmonary permeability. Orthopedic trauma was induced in both hindlimbs in lean (LZ) and obese Zucker rats (OZ). On the following day, plasma interleukin-6 (IL-6) and PGE(2) levels, pulmonary edema, and pulmonary gas exchange capability were compared between groups: LZ, OZ, LZ with trauma (LZT), and OZ with trauma (OZT). Vascular permeability in isolated lungs was measured in LZ and OZ before and after application of PGE(2) . As compared with the other groups, the OZT exhibited elevated plasma IL-6 and PGE(2) levels, increased lung wet/dry weight ratio and bronchoalveolar protein concentration, and an impaired pulmonary gas exchange. Indomethacin treatment normalized plasma PGE(2) levels and pulmonary edema. Basal pulmonary permeability in isolated lungs was higher in OZ than LZ, with a further increase in permeability following treatment with PGE(2) . These results suggest that pulmonary edema in OZ following orthopedic trauma is due to an elevated PGE(2) and resultant increases in pulmonary permeability.

    ABSTRACT: The treatment of complex diaphyseal malunions is challenging, requiring extensive preoperative planning and precise operative technique. We have developed a simpler method to treat some of these deformities. Ten patients with complex diaphyseal malunions (including four femoral and six tibial malunions) underwent a clamshell osteotomy. The indications for surgery included pain at adjacent joints and deformity. After surgical exposure, the malunited segment was transected perpendicular to the normal diaphysis proximally and distally. The transected segment was again osteotomized along its long axis and was wedged open, similar to opening a clamshell. The proximal and distal segments of the diaphysis were then aligned with use of an intramedullary rod as an anatomic axis template and with use of the contralateral extremity as a length and rotation template. The patients were assessed clinically and radiographically at a mean of thirty-one months (range, six to fifty-two months) after the osteotomy. Complete angular correction was achieved in each case; the amount of correction ranged from 2° to 20° in the coronal plane, from 0° to 32° in the sagittal plane, and from 0° to 25° in the axial plane (rotation). Correction of length ranged from 0 to 5 cm, and limb length was restored to within 2 cm in all patients. All osteotomy sites were healed clinically by six months. While no deep infections occurred, superficial wound dehiscence occurred in two patients along the approach for the longitudinal portion of the osteotomy, emphasizing the importance of careful soft-tissue handling and patient selection. The clamshell osteotomy provides a useful way to correct many forms of diaphyseal malunion by realigning the anatomic axis of the long bone with use of a reamed intramedullary rod as a template. This technique provides an alternative that could decrease preoperative planning time and complexity as well as decrease the need for intraoperative osteotomy precision in a correctly chosen subset of patients with diaphyseal deformities.

    ABSTRACT: Open treatment of pilon fractures is associated with wound healing complications. A traumatized, limited soft tissue envelope contributes to wound healing complications. Obese patients have larger soft tissue envelopes around the ankle, theoretically providing a greater area for energy distribution and more accommodation to implants. This led us to test 2 hypotheses: (1) ankle dimensions in obese patients are larger than in lean patients, and (2) the increased soft tissue envelope volume translates into fewer wound complications. A consecutive series of 176 pilon fractures treated from March 2002 to December 2007 were retrospectively reviewed. Inclusion criteria were adults who received a preoperative computed tomography (CT) scan and were treated with a staged protocol including plating. Patients with body mass index (BMI) >30 were compared to those with BMI <30 for CT-derived ankle dimensions and wound complications. Comorbidities were evaluated for their role as potential confounders. Thirty-one fractures in obese patients were compared to 83 in lean patients. The average ratio of bone area to soft tissue area at the tibial plafond was 0.35 for the obese group and 0.38 for the lean group (P=.012). There were 8 major wound-healing complications. Four occurred in the obese group (incidence 13%), and 4 in the lean group (incidence 5%) (P=.252). Ankle dimensions in clinically obese patients are larger than in lean patients. Obesity does not appear to be protective of wound-healing complications, but rather there is a trend toward the opposite.

    ABSTRACT: The femoral region of rats is commonly used in biomedical research and surgical training throughout the world. This study reports on an easier and more efficient surgical approach, the Fanua–Wilgis (FW) technique, for dissecting and exposing the femoral artery in the rat model that differs from the traditional longitudinal technique. The traditional longitudinal techniques call for an incision perpendicular to the length of the inguinal field. The epigastric fat pad then is dissected and retracted laterally to avoid damage to the superficial epigastric vessels (Figure 1). The femoral neurovascular bundle is then exposed. The neurovascular bundle should be located between the vastus medialis muscle and adductor longus muscles on the surface of the pectineus. The FW technique involves marking the skin in the groin region in the shape of a “C” (Figure 2). The incision follows the mark, exposing the epigastric fat pad and the pyramidalis muscle (Figure 3). Dissection proceeds by retracting the skin and epigastric fat pad (Figure 4), thereby, exposing the femoral neuromuscular bundle (Figure 5). Wound closure for both techniques is done by individual simple sutures in the skin (Figure 6). Time to arterial exposure, bleeding, and complications for the two techniques were compared. The study was approved by the IACUC of MedStar Research Institute, and all animal care procedures followed the NRC guidelines. All operations were carried out with the animals under anesthesia with sodium pentobarbital (50 mg/kg body weight) given intraperitoneally. Forty rats were used. The FW technique was used in 20 rats (n = 20) with an average of 3 min from the time of incision to femoral exposure. There were no complications noted. The amount of bleeding was measured on a scale of 1 to 3. Light bleeding (1) was noted in 30% of the rats, but stopped completely after 1 min of applied pressure. Moreover, the average amount of bleeding using the FW technique was 0.33 mL per animal. By comparison, on the 20 rats (n = 20) where the longitudinal technique was used, it took an average of 9 min (n = 20) from the time of incision to femoral exposure. Heavy bleeding (3) was noted in 25% of the animals, medium bleeding (2) in 20%, light bleeding (1) in 20%, and only 30% had no bleeding. Bleeding was controlled by the application of pressure. There was one complication—an animal expired, presumably due to blood loss. The average amount of bleeding using the longitudinal technique was 1.55 mL per animal. All animals were euthanized right after the surgery, so no postoperative analgeisa or observations were required.
