Low energy gunshot injuries: Does removal of retained bullet fragmentation at the time of internal fixation reduce the risk of fracture related infection?

OBJECTIVE: To examine the effects of RBF (Retained Bullet Fragment) removal at the time of long bone fixation on FRI (fracture related infection) rates in low energy GSI (Gunshot Injury) related fractures. DESIGN: Retrospective Cohort Study SETTING: Level 1 Academic Trauma Center INTERVENTION: Retrospective review of the impact of RBFs on the risk of FRI when employing internal fixation in low energy GSI (Gunshot Injury) related fractures. In situations where the injury pattern requires surgical fixation, the question arises as to whether or not the RBFs need to be removed to prevent FRI. MAIN OUTCOME MEASURES: Whether or not the RBFs removed in our patient population prevented short- and long-term fracture related infection after low-energy gunshot injury (FRI-LGI). RESULTS: Of the 2,136 GSI related fractures, 131 patients met inclusion criteria, 81 patients underwent removal (R) of RBFs at the time of internal fixation while 50 patients did not undergo any removal (NR) at time of internal fixation. Among the patients who underwent surgical intervention, (Open Reduction Internal Fixation) ORIF was performed in 55 cases (R: 39; NR: 16), and (Intramedullary Nail) IMN was performed in 76 cases (R: 42; NR: 34). The overall rate of deep FRI-LGI was 6.9 % of the 131-patient cohort. We found that removal of RBFs had a statistically significant impact on the rate of deep FRI-LGI when compared to the NR group (p = 0.031). In the RBF removal group, only two patients (2.4 %) developed deep FRI-LGIs, whereas in the NR group, seven patients (14.0 %) developed deep FRI-LGIs. The incidence of early FRI-LGI was higher in the NR group (median 0.6 months) compared to the R group, which was associated with late FRI-LGIs (median 10.1 months) when they occurred. DISCUSSION: In our study population, we found a statistically significantly increased incidence of deep and early FRI-LGI when RBFs are not removed at the time of extra-articular long bone internal fixation. The presence of retained bullet fragments following internal fixation may pose a risk factor for future development of deep FRI-LGI. We believe a surgeon should use their best judgment as to whether a RBF can safely be removed at the time of long bone fixation. Based on our findings, if safely permitted, RBF removal should be considered at the time of GSI long bone fixation resulting from low energy hand gun injuries.

Atraumatic Exertional Compartment Syndrome of the Medial Foot: Case Report.

Introduction: Acute compartment syndrome is a surgical emergency that is mainly diagnosed clinically. Acute exertional compartment syndrome of the medial compartment of the foot is a rare condition most often result from strenuous exercise. Early diagnosis is most often a clinical examination, however, laboratory and magnetic resonance imaging (MRI) can assist in the diagnosis if clinician uncertainty persists. We present a case report of acute exertional compartment syndrome of the medial compartment of the foot after physical activity. Case Report: A 28-year-old male presents to the emergency department the day after playing basketball, with severe atraumatic medial foot pain. Clinical examination demonstrated tenderness and swelling over the medial arch of the foot. Creatine phosphokinase (CPK) results at 9500 international units. MRI demonstrated fusiform edema of the abductor hallucis. Subsequent fasciotomy revealed protruding muscle during fascial incision and relieved the patient of their pain. Return to surgery 48 h after initial fasciotomy revealed gray discoloration and lack of contractility of the muscle tissue. The patient was recovering well at the first post-operative visit, however, was lost to follow-up thereafter. Conclusion: Acute exertional compartment syndrome of the medial compartment of the foot is a rarely reported diagnosis, likely due to a combination of missed diagnosis and underreporting. Laboratory tests for CPK may be elevated, and MRI may be helpful in the diagnosis of this condition. Fasciotomy of the medial compartment of the foot relieved the patient's symptoms, and to our knowledge had a good outcome.

Accuracy of Leg Length and Hip Offset Measurements Using a Fluoroscopic Grid During Anterior Approach Total Hip Arthroplasty.

Background: Minimizing leg length (LLD) and hip offset (OD) discrepancies is critical for tissue tension and implant longevity in total hip arthroplasty (THA). The direct anterior approach (DAA) helps surgeons recreate these values under fluoroscopy. Several methods to accomplish this have been described, with no consensus on which is superior. This study evaluated the ability to minimize LLD and OD using a surgeon-controlled, adjustable fluoroscopic grid. We hypothesized that this tool would recreate parameters to within 10 mm of the contralateral side. Methods: One hundred eleven primary THAs performed with an adjustable radiopaque grid to equalize leg length and hip offset were retrospectively reviewed. These values were measured on postoperative radiographs and compared to the contralateral hip. Patients were excluded if they had inadequate imaging, revision arthroplasty, preexisting deformities, or underwent approaches other than DAA. Results: Mean age was 59.1 ± 11.1 years, 63.1% of patients were female, and average body mass index was 27.8 ± 7.0. Mean LLD was 3.7 ± 3.0 mm, while mean OD was 4.6 ± 3.6 mm. 95.5% of hips showed LLD < 10 mm, while 93.7% of hips had OD < 10 mm. Furthermore, 76.6% of hips had LLD < 5 mm, while 62.2% of hips had OD < 5 mm. Conclusions: The described technique restored limb length and hip offset during DAA THA. This technique yields consistent results and offers an inexpensive alternative to costly digital software and more cumbersome fixed grid systems.

Impact of a Dedicated Orthopaedic Trauma Room on Elective Arthroplasty Case Volume.

OBJECTIVE: To examine the effects of implementing a dedicated orthopaedic trauma room (DOTR) on elective arthroplasty volume. DESIGN: Retrospective cohort study. SETTING: Level I academic trauma center. INTERVENTION: A retrospective analysis was performed for two 3-year intervals before and after DOTR introduction on January 20, 2013, at a Level I trauma center. Surgeons were included if they performed elective primary total hip arthroplasty (THA), total knee arthroplasty (TKA), total shoulder arthroplasty (TSA), or reverse total shoulder arthroplasty (RTSA) regularly from 2010 to 2015. MAIN OUTCOME MEASURES: Change in elective arthroplasty volume after the implementation of a DOTR. RESULTS: A total of 2339 cases were performed by surgeons A-E, with an average of 303.3 cases per year pre-DOTR and an average of 476.3 cases per year post-DOTR. On average, within our institution, there were 75.79 per 10,000 cases/year in Michigan pre-DOTR and 104.2 per 10,000 cases/year in Michigan post-DOTR. Surgeons A-E averaged 173.0 more cases per year and increased their average proportion of elective arthroplasty case volume in Michigan. There was a statistically significant market share increase of 9.8 per 10,000 cases/year in Michigan, at our hospital in the post-DOTR periods ( P = 0.039) (CI [0.5442, 19.21], SE = 4.523). This market share increase of 9.8 cases/10,000 cases was the yearly increase in market share that our average surgeons saw after the DOTR implementation, this took into account the observed annual increase in arthroplasty volume statewide during those years. CONCLUSION: Implementation of a DOTR was associated with increases in the total number, annual mean, and annual proportion of elective arthroplasty cases performed in Michigan for both elective surgeons and the institution as a whole. These findings reveal a benefit of DOTR implementation to elective arthroplasty surgeons and health systems on a larger scale, in the form of increased arthroplasty case volume.

Does Hip Fracture Admitting Service Affect Proper Deep Venous Thrombosis Prophylaxis? An Investigation at a Level 1 Trauma Center.

OBJECTIVE: To examine if rates of appropriate thromboprophylaxis prescribing at the time of discharge would be higher in patients admitted to the orthopaedic service. Second, to see if improvements could be made in the rates of these missed events after a structured intervention. DESIGN: Retrospective Cohort Study, Prospective Interventional. SETTING: Level 1 Academic Hospital. PATIENTS: Two hundred forty-six patients undergoing a hip hemiarthroplasty for femoral neck fracture discharged to an extended care facility. INTERVENTION: A letter was sent to the internal quality control committee detailing our preintervention study. MAIN OUTCOME MEASURE: We looked at the differences among admitting services for missed thromboembolic prophylaxis (TPx) at the time of hospital discharge and rates of appropriate TPx after a structured intervention. RESULTS: No statistically significant differences existed in relation to patient age, gender, body mass index, or postoperative discharge day in the preintervention group. Orthopaedic surgery prescribed adequate TPx at discharge for 76 of 77 patients (98.7%), general trauma surgery for 26 of 30 patients (86.7%), and internal medicine for 85 of 96 patients (86.7%) in the preintervention group. There was a statistically significant difference when comparing adequate TPx between orthopaedic surgery and other services (P < 0.013 and <0.021, respectively). Our postintervention data found a significant decrease in the rates of missed TPx on discharge. In our preintervention sample group compared with our postintervention sample group, we saw a decrease in missed TPx of 5/39 versus 0/43 events (P = 0.021). CONCLUSIONS: We found that a letter sent to all members of a hospital internal quality committee decreased incidences of missed TPx. Specifically, this letter explained the details of our study that kept track of rates of missed TPx among different admitting services. We found that after our intervention, which consisted of a letter and a multidisciplinary discussion, the rate of missed thromboembolic prophylaxis events improved from 5/39 (12%) to 0/43 (0%) (P = 0.021). LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Implementation of a Dedicated Orthopaedic Trauma Room in Hip and Femur Fracture Care: A 17-Year Analysis.

OBJECTIVE: To examine the effects of implementing a dedicated orthopaedic trauma room (DOTR) on hip and femur fracture care. DESIGN: A retrospective cohort study. Setting: Level 1 trauma center. Patients: 2928 patients with femoral neck, pertrochanteric, and femoral shaft and distal femur (FSDF) fractures. INTERVENTION: Implementation of a DOTR. MAIN OUTCOME MEASURES: Hospital length of stay (LOS), emergency department (ED) LOS, intensive care unit (ICU) LOS, and time to operating room (TTOR). RESULTS: Implementation of a DOTR resulted in significant improvement in TTOR for all patient groups ( P < 0.05). We found shorter TTOR for pertrochanteric ( P < 0.001), femoral neck ( P = 0.039), and FSDF groups ( P = 0.046). Total hospital LOS was shorter for patients with pertrochanteric ( P < 0.001) and femoral neck fractures ( P = 0.044). Patients with pertrochanteric hip fractures demonstrated shorter ICU LOS ( P < 0.001). No LOS improvements were observed among patients in the FSDF group. ED LOS was significantly longer in all patient groups ( P < 0.001). CONCLUSIONS: Implementation of a DOTR was associated with shorter TTOR, shorter hospital and ICU LOS, and longer ED LOS. There was a greater number of patients transferred into the investigating institution and fewer patients transferred out. These data support the utility of a DOTR as it relates to an improvement in hospital stay-related outcomes in patients with fractures of the hip and femur. Our results suggest that a DOTR in a Level I trauma hospital is associated with improvement in patient care. LEVEL OF EVIDENCE: Therapeutic Level III.

Does seasonal variation in orthopaedic trauma volume correlate with adverse hospital events and burnout?

INTRODUCTION: Assessing workload and mitigating burnout risk should be a constant goal within training programs. By using work relative value unit (wRVU) data in a non-elective orthopaedic trauma practice, we investigated seasonal variation in workload on an orthopaedic trauma service at a level I trauma centre. We also investigated whether there was a correlation in seasonal preventable adverse patient safety events (PSEs) and resident Epworth Sleepiness Scale (ESS) scores. MATERIALS AND METHODS: Data on wRVUs were collected over an 8-year period for a single orthopaedic trauma surgeon with a non-elective practice. Monthly wRVU totals were tabulated over this 8-year period and compared with total hospital orthopaedic surgical trauma volume. The total number of wRVUs and surgical cases analysed were 80,955 and 9,928 respectively. A total of 1,560 PSEs and four years of resident ESS scores were analysed. Data on seasonal variations was evaluated for significance utilizing the Kruskal-Wallis test. WRVUs were then compared to total case volume, PSEs, and resident ESS scores using Spearman's correlation coefficients. RESULTS: We found that wRVUs significantly differed by month (P-value < 0.001) and season (P-value < 0.001) with the highest volume occurring in the summer months. Seasonal variation in wRVUs demonstrated a positive linear correlation with total surgical volume (P-value <0.001) and resident reported ESS scores (P-value = 0.001). PSEs were highest in the summer (P = 0.026), but were not correlated with our findings of seasonal variations in orthopaedic volume (P-value = 0.741). CONCLUSION: WRVUs of our single surgeon's orthopaedic trauma practice had a seasonal variation with significantly higher volume during the summer. These findings were representative of seasonal variations in total hospital orthopaedic trauma volume and also demonstrated correlation with objective resident sleepiness scores. PSEs were more frequent in the summer but not correlated with seasonal variation in volume. Burnout poses a risk to patient safety and has been shown to be correlated with increased work volume. These topics are important and applicable to various specialties involved in the care of patients with orthopaedic trauma injuries.

Use of a modified retrograde femoral rod as a custom length tibiotalocalcaneal nail.

There has been increasing interest in the use of hindfoot tibiotalocalcaneal (TTC) nails to treat ankle and distal tibia fractures in select patient populations who are at increased risk for soft tissue complications after open reduction and internal fixation with traditional plate and screw constructs. We describe a technique which uses a retrograde femoral nail as a custom length TTC nail. By using a simple modification of the insertion jig, we are able to achieve safe screw trajectories that allow for robust distal interlocking fixation. Review of implantation in multiple cadaveric specimens demonstrates safe placement of distal screw fixation in the calcaneus without risking injury to important neurovascular structures. Because of the 2-cm incremental length options of this particular device, we are able to achieve supraisthmal fixation in the tibia which may lessen the risk for fracture that may be more likely to occur at the tip of a short TTC nail option. Furthermore, a custom length TTC nail is more costly and also requires advanced notice to acquire for the case; retrograde femoral nails are readily stocked and accessible at our level 1 trauma center. This TTC technique offers anatomic restoration while also offering convenience, instrument familiarity, cost savings, and increased patient safety.

Categorization of Adverse Events Reported to the FDA Pertaining to Tibia Intramedullary Nailing.

OpenFDA is an open access database maintained by the United States Food and Drug Administration (FDA) that we queried for adverse events (AEs) related to product devices used during tibia intramedullary nailing (IMN) procedures. There was a total of 1,799 reports pertaining to tibial intramedullary nailing from 1996 to 2020. Causes included infection (451), nonunion (380), intraoperative issue (343), painful hardware (234), implant fracture (195), other (68), loosening (35), surgeon error (24), packing problem (24), patient injury (12), expiration (12), contamination (11) and allergic reaction (10). The total number of events increased in 2016 and 2018, which was attributed to 510k approval for Stryker. Of the Aes, 1,400 resulted in an injury to the patient. In total, 78% occurred in the post-operative period, and 68% required additional surgery. Most incidents related to tibia IMNs result in injury and require additional surgery. When new products are released, AEs occur quickly and in bulk. (Journal of Surgical Orthopaedic Advances 31(4):237-241, 2022).

Can the implementation of the Opioid Start Talking form impact the amount of opioid use in patients after ankle fracture repair?

OBJECTIVE: As part of 2018 legislation aimed at fighting the opioid epidemic, the Michigan Department of Health and Human Services (MDHHS) published the "Opioid Start Talking" (OST) Form on June 1, 2018. We examined if the implementation of the OST form led to an identifiable decrease in patient opioid use. Specifically, we examined the opioid prescription quantities in patients who sustained ankle fractures that required open reduction internal fixation (ORIF). DESIGN: Retrospective. Hospital medical records and Michigan Automated Prescription Database (MAPS) were analyzed for similar ankle fracture patients operated on by two surgeons prior to and after the initiation of the OST form. Records allowed us to track opioid filling through MAPS for 120 days after surgery in two groups: preimplementation (PRE) and post-implementation (POST) OST groups. The gathered data were analyzed by the investigators along with a staff statistician. SETTING: Single-institution orthopedic practice. PATIENTS, PARTICIPANTS: Seventy eight patients Main outcome measure: Average morphine milligram equivalent (MME) per patient encounter. RESULTS: Seventy eight patients were included in the final analysis after applying the exclusion criteria. There were 38 patients in the pre-OST form period and 40 in the post-OST form period groups. The pre-OST and post-OST groups were well matched between the two surgeons. There was no evidence of a statistically significant difference found in the median MME between patients from the pre-period group to the post-period group (median 59 vs 50, P = 0.61). In regard to the injury pattern, the bimalleolar MME median was 50 (38 = 25th percentile, 67 = 75th percentile; min-max 0-175) and the trimalleolar median MME was 63 (39 =25% percentile, 81 = 75th percentile; min-max 0-249) with a P value of 0.20. CONCLUSIONS: Overall, the administration of the OST form to patients with ankle fractures did not result in a decrease in MMEs prescribed within 120 days of surgery. Although it is a start in the battle against the opioid epidemic, further evaluation of the effectiveness of the OST form is necessary.

Comparing Postoperative Leg Length Discrepancy and Femoral Offset Using Two Different Surgical Approaches for Hemiarthroplasty of the Hip.

INTRODUCTION: The direct anterior approach (DAA) and anterolateral approach (ALA) may be used for hip hemiarthroplasty (HHA) as a treatment for femoral neck fractures. The DAA often utilizes intraoperative fluoroscopy to determine leg length and offset, while the ALA traditionally utilizes an intraoperative clinical exam to determine offset and leg length. This study will evaluate two techniques: the "grid fluoroscopy [GF] technique" and the "intraoperative exam [IE] technique," each performed by one of two separate surgeons, and compare each technique's accuracy to restore leg length and femoral offset in a patient population that underwent HHA. METHODS: Two investigators retrospectively reviewed charts of 208 randomly selected patients who had an HHA from either a DAA or ALA performed by two different surgeons for the treatment of femoral neck fractures. Postoperative AP pelvis radiographs were measured to determine offset and leg length compared with the non-operative extremity. Non-normal continuous variables were provided by median and interquartile range. Data were analyzed with the Mann-Whitney U test and Student's t-test. RESULTS: After inclusion and exclusion criteria, data were reviewed on 173 hemiarthroplasties. The mean age was 80.3 years (± 11.2 years). Of the surgical patients, 65.9% were female, and 70.9% identified their ethnicity as white. The DAA was used in 93 patients and ALA in 80 patients. Analysis comparing the two techniques demonstrated no statistically significant differences in median leg length between GF technique (1.02 IQR -0.1, 2.0 mm) and IE technique (1.25 IQR -2.4, 1.3 mm,) (p=0.67). There was also no statistically significant difference in offset between GF technique (1.3 IQR 0.2, 2.1 mm) and IE technique (0.6 IQR -2.7 mm, 3.2 mm) (p=0.13). However, a difference was found in mean length of surgery that was statistically significant. We found that the mean length of surgery for the IE technique was 74.8 ± 24.7 minutes versus the GF technique, which was 95.1 ± 23.0 minutes, (p<0.0001). DISCUSSION: There was no significant difference between leg length and offset with the use of intraoperative fluoroscopy with DAA compared to no intraoperative imaging with ALA. Our study suggests that DAA and ALA are equally effective approaches for re-establishing symmetric leg length and offset in HHA for femoral neck fractures. In this study, the ALA had a shorter surgical time compared to DAA, potentially due to the utilization of intraoperative fluoroscopy for this particular technique during the DAA.

A Fixed, Unreducible, Unstable Medial Swivel Dislocation of the Talonavicular Joint with Associated Navicular Fracture.

A 32-year-old white male was on a second-story balcony when he fell off and landed on the cement below. With initial X-rays being read as negative on the radiology report due to the subtle nature of the injury, the patient was promptly diagnosed with a medial swivel dislocation by the orthopaedic team, which ended up being fixed, unstable, and irreducible. The patient also had acute skin compromise and needed to be taken to the operating room prior to progression of skin breakdown. This dislocation pattern is a rare variant, especially when paired with the fixed nature of the dislocation and the soft tissue compromise. In the end, open treatment was necessary in order to reduce the talonavicular joint. Because of early recognition and prompt treatment, skin breakdown was avoided. Internal screw fixation of the fractured navicular bone was needed along with K-wire insertion to hold the normal anatomy of the talonavicular joint reduced. All hardware was ultimately removed after healing, and anatomy was restored with excellent patient function. This case report highlights the orthopaedic knowledge needed to not only recognize this rare fracture-dislocation pattern but to also treat it promptly when encountered.

The Effect of Different Irrigation Solutions on the Cytotoxicity and Recovery Potential of Human Osteoblast Cells In Vitro.

BACKGROUND: Surgeons use various irrigation solutions to minimize the risk of prosthetic joint infection after total joint arthroplasty. The toxicity of these solutions is an important consideration in their use. This study investigates the effect of irrigation solutions Bacitracin, Clorpactin (sodium oxychlorosene), and Irrisept (chlorhexidine) on osteoblast cytotoxicity and proliferation. METHODS: Four replicates of 6 conditions at 3 time points (1, 2, and 4 min) were tested: control (normal saline), Bacitracin (33 IU/ml), Clorpactin (0.05%, 0.1%, 0.2%), and Irrisept (0.05% chlorhexidine gluconate). Human osteoblasts were cultured at 37°C and 5% CO2 until confluent monolayers were obtained. The treatment solution was applied, and cells were washed 3x with warm phosphate-buffered saline and then supplemented with a fresh medium. Phase-contrast images were taken before and after treatment. The cytotoxicity and proliferation of the treated cells was measured for all conditions on day 3 and day 5 after treatment using the alamarBlue assay. RESULTS: All test conditions showed morphological changes to cells after treatment; controls did not. Cells demonstrated curling and detachment. This effect was the worst and permanent with Irrisept, whereas other treatments showed a return to normal morphology after 1 week. All treatments showed increased %alamarBlue reduction after 5 days except Irrisept, which showed decreased reduction. There was no statistically significant time or dose dependence with Clorpactin treatment. CONCLUSIONS: Clorpactin and Bacitracin are damaging to human osteoblast cells in vitro as compared with normal saline. This damage is at least partially reversible as shown by morphology and cell viability assay. Irrisept caused more damage than either Clorpactin or Bacitracin, and the damage was not reversible.

Aberrant radial-ulnar nerve communication in the upper arm presenting as an unusual radial nerve palsy: a case report.

An unusual communication between the radial and ulnar nerves was observed during repair of a fracture of the humerus in an adult patient who presented with unusual physical exam findings. The patient had loss of radial and ulnar nerve motor function, as well as decreased sensation in both nerve distributions. Radial nerve injury following fracture of the humerus is a common condition, and anatomic variations are therefore of importance to clinicians. Communications between branches of the brachial plexus are also not uncommon findings; however there is very little mention of communication between the radial and ulnar nerves in the literature. An appreciation of unusual nerve anatomy is important in explaining unusual finding in patients.

Clamp-assisted reduction of high subtrochanteric fractures of the femur: surgical technique.

BACKGROUND: Subtrochanteric fractures can be a treatment challenge. The substantial forces that this region experiences and the fact that the proximal fragment is frequently displaced make accurate reduction and internal fixation difficult. The purpose of this study was to evaluate a series of patients who had undergone clamp-assisted reduction and intramedullary nail fixation to determine the impact of this technique on fracture union rates and reduction quality. METHODS: Between December 2003 and January 2007, fifty-five consecutive patients with a displaced high subtrochanteric femoral fracture were treated with clamp-assisted reduction and intramedullary nail fixation at two level-I trauma centers. Two patients died, and nine were lost to follow-up. The remaining forty-four patients were followed until union or a minimum of six months. There were twenty-seven male and seventeen female patients with a mean age of fifty-five years. All were treated with an antegrade statically locked nail implanted with a reaming technique as well as the assistance of a reduction clamp placed through a small lateral incision. Nine patients were treated with a single supplemental cerclage cable. Radiographs were evaluated for the quality of the reduction and fracture union. RESULTS: Forty-three of the forty-four fractures united. All reductions were within 5° of the anatomic position in both the frontal and the sagittal plane. Thirty-eight (86%) of the forty-four reductions were anatomic. Six fractures had a minor varus deformity of the proximal fragment (between 2° and 5°). There were no complications. DISCUSSION: Surgical treatment of subtrochanteric femoral fractures with clamp-assisted reduction and intramedullary nail fixation techniques with judicious use of a cerclage cable can result in excellent reductions and a high union rate. Careful attention to detail is important to perform these maneuvers with minimal additional soft-tissue disruption.

The anterior intra-pelvic (modified rives-stoppa) approach for fixation of acetabular fractures.

OBJECTIVES: Report the technical aspects, radiographic results, and complications after minimum 1-year follow up of the anterior intra-pelvic (AIP or modified Rives-Stoppa) approach as an alternative to the ilioinguinal approach for the treatment of acetabular fractures. DESIGN: Retrospective review. SETTING: Level I trauma center. MATERIALS AND METHODS: All skeletally mature patients requiring an anterior approach for fixation of an acetabular fracture with minimum 1-year clinical and radiographic follow up were included. Charts and radiographs were reviewed for fracture pattern, time to surgery, operative time, blood loss, quality of reduction, and perioperative complications. A consecutive group of 57 patients treated by a single surgeon using the AIP approach was identified as a subset of a larger series 536 acetabular fractures treated by the same surgeon between February 2004 and February 2008. RESULTS: Of the 57 patients, average time to operation was 5 days and a supplemental lateral window was required in 34 patients (60%). Average blood loss was 750 mL, and average operative time was 263 minutes. One patient (1.8%) had a vascular injury requiring embolization. One patient (1.8%) had a wound infection in the lateral window, two patients (3.5%) developed a direct inguinal hernia requiring surgical repair, and one patient (1.8%) had atrophy of the ipsilateral rectus abdominus without hernia. Of the 50 patients with minimum 1-year follow up, there were 22 associated both column, 12 anterior column, seven anterior column posterior hemitransverse, six transverse, and three T-type fractures. Seventy percent of the reductions were graded excellent, 22% were graded good, and 8% poor. Clinical outcomes (Merle D'Aubigne) at 1 year were 36% excellent, 55% good, and 10% poor. Thirteen patients (26%) were noted to have significant weakness of the hip adductors (obturator nerve palsy) postoperatively; all but one resolved and improved within 6 months. CONCLUSION: Use of the AIP (modified Rives-Stoppa) approach for the treatment of acetabular fractures permits good to excellent reduction in the majority of cases while giving excellent visualization and access to the quadrilateral plate and posterior column. The AIP approach has a complication rate that is comparable to the ilioinguinal approach. We recommend the use of this technique as a potential alternative (but not replacement) to the classic ilioinguinal approach when anterior exposure of the acetabulum is required.

Outcome analysis of pancreaticoduodenectomy at a community hospital.

There is an ongoing debate about the proposed regionalization of pancreaticoduodenectomies. The purpose of our study is to demonstrate that good outcomes can be achieved in a well-managed low-volume community hospital. We retrospectively analyzed pathologic findings, morbidity, mortality, and one-year survival in 32 patients who underwent pancreaticoduodenectomy at Providence Hospital over a 10-year period and compared these results with data collected at Johns Hopkins, and the Mayo Clinic. The patients had a mean age of 68.5 +/- 2.96 years; 56.3 per cent were female and 71.9 per cent were white. Overall in our series 90.6 per cent of specimens were found to be malignant, which is statistically higher than the 68 per cent at Johns Hopkins (P = 0.013) and not significantly different from Mayo Clinic (76%). The 30-day mortality rate at Providence Hospital was 3.1 per cent, which is not statistically different from Johns Hopkins (1.3%) and Mayo Clinic (3.6%). One-year survival rate at Providence Hospital was 59.4 per cent, which is significantly different from 79 per cent at Johns Hopkins (P = 0.016). The one-year survival rate at Providence Hospital is higher than an approximately 50 per cent average reported nationally. The postoperative complication rate was 62.5 per cent; the most common complication was delayed early gastric emptying (28.1%). A statistical difference in morbidity exists between Providence Hospital and Johns Hopkins (P = 0.027) but not between Providence Hospital and Mayo Clinic (46%). The higher rate of malignant disease treated in the population at Providence Hospital may contribute to a higher complication rate and lower one-year survival rate than the reported rates at Johns Hopkins because of the poorer health of cancer patients. However, statistical analysis of mortality rates for pancreaticoduodenectomy at Providence Hospital show no difference from mortality rates at Johns Hopkins and Mayo Clinic. Therefore in low-volume community hospitals pancreaticoduodenectomy can be performed safely as evidenced by a comparable low mortality rate and a high one-year survival rate.
