Complications and survival rates of subtrochanteric fractures are similar between short and long intramedullary nail fixation and independent of weight-bearing.

PURPOSE: Intertrochanteric fractures are treated surgically, allowing rapid weight-bearing to improve ambulation and lower complications and mortality. Subtrochanteric fractures are mechanically less stable and are traditionally treated with a non-weight approach and longer intramedullary nails. This study compared immediate weight-bearing versus limited weight-bearing and different intramedullary nail lengths regarding patient outcomes. METHODS: We analyzed all consecutive cases of low-energy subtrochanteric fractures treated surgically at our institution between January 2016 and November 2020. One hundred and nine patients were found. We compared nail length and immediate versus delayed weight-bearing concerning the length of stay, time to painless ambulation, time to radiographic fracture union, and revision rates. Fracture severity was also examined using the Seinsheimer classification. RESULTS: Length of stay and time to painless ambulation were shorter in the immediate weight-bearing group. Time to radiographic union and rate of complications were lower; however, they were not statistically significant. Conversely, no significant difference in revision rates was found. Regarding nail length, the length of stay was shorter, and the time to painless ambulation was faster in the short-length group. The rate of complications and time to union were similar. No difference in revision rate was found. Seinsheimer classification of the fracture did not influence the decision to allow weight-bearing or nail selection (p = 0.65). CONCLUSIONS: This study demonstrates that immediate weight-bearing as tolerated and short intramedullary nails allow a quicker time for painless ambulation and hospitalization, with possibly fewer perioperative complications and faster radiographic union, without increasing complications.

Cost Analysis of a Fracture Liaison Service: A Randomized Controlled Trial for the Secondary Prevention After Fragility Fractures of the Hip.

OBJECTIVE: Fracture liaison services (FLSs) have proven to be effective for secondary fracture prevention. In this study, we evaluated the essential factors in determining whether the FLS saves or loses more than it costs. METHODS: A randomized controlled trial was performed in patients with hip fragility fractures using a hospital-based FLS program in parallel with a cost analysis. Data were generated from a cohort of patients using actual data for FLS effectiveness, individual costs of hip fracture treatment, and medication costs based on an accepted treatment algorithm. RESULTS: A total of 200 patients were randomized, and 180 were analyzed for costs. The FLS program had an overall cost despite the savings in reducing secondary fractures. Medication was 89% of the costs and was the main factor for the FLS costs exceeding the savings. Specifically, using the medication algorithm in this study, the overall cost per patient enrolled in the FLS was $1189 for a 2-year period. If intravenous zoledronic acid had been used, then the overall cost would have been $489. If only oral bisphosphonates had been used, then the FLS would have cost $159 per patient for a 2-year period. CONCLUSION: The present analysis shows that medication cost is the critical component in cost-effectiveness of an FLS program. The FLS program costs would be significantly lower if patients are prescribed less expensive drugs to treat osteoporosis. Additional work needs to be performed refining the medication algorithm considering medication costs but individualized to patient needs based on fracture risk.

Neck of femur fractures treated with the femoral neck system: outcomes of one hundred and two patients and literature review.

INTRODUCTION: The recently developed femoral neck system (FNS) for treatment of femoral neck fractures (FNF), comprises theoretical biomechanical advantages compared to other implants. The aim of this study was to validate the safety and to report outcomes of patients treated with the FNS. METHOD: A retrospective multicentric analysis of patients treated by FNS with a minimum of three months of follow-up. Details analysed from three medical centres were operative duration, estimated blood loss, initial hospitalisation duration, fixation quality as well as complications and reoperation rate. Patients who had revision surgery were compared to all other patients to identify risk factors for failure. In addition, a literature review was performed to analyse data on FNS clinical implementation and patient's outcomes. The two data sets were combined and analysed. RESULTS: One-hundred and two patients were included in this study cohort with an average follow-up of seven months (range 3-27). Ten papers were included in the literature review, reporting data on 278 patients. Overall, 380 patients were analysed. Average age was 62.6 years, 52% of the fractures were classified as Gardens 1-2. Overall, the revision rate was 9.2% (14 patients diagnosed with cut-out of implant, 10 with AVN, 8 with non-union and 8 with hardware removal). For the 102 patients in the cohort risk factors for reoperation included patients age, surgeon seniority and inadequate placement of the implant. CONCLUSION: This study shows that FNS is a safe treatment option for FNF. Intra-operative parameters and failure rates are comparable to previously reported rates for this implant and other frequently used implants.

Wrist Ganglia in Children: Nonsurgical Versus Surgical Treatment.

PURPOSE: To compare the outcomes of nonsurgical and surgical treatment of children with wrist ganglia. METHODS: We performed a retrospective review of children with wrist ganglia treated at 2 separate institutions. In one, a clinic setting, children were treated with observation. In the other, a hospital referral center, children had surgical excision. Information obtained included persistent or recurrent cyst, and Quick-Disabilities of the Arm, Shoulder, and Hand measure. Patients aged 17 years or less at the time of cyst appearance with at least 1 year of follow-up were included. RESULTS: We successfully contacted 90 patients: 50 in the nonsurgical and 40 in the surgical group. Average follow-up was 4.6 years. The persistence rate in the nonsurgical group was 52%. The recurrence rate in the surgical group was 15%. In the nonsurgical group, if a ganglion resolved, it did so within 18 months in 94% of patients. Dorsal ganglions persisted more often than volar ones (63% vs 33%). Older children had a higher rate of persistence than did younger children (58% vs 31%). For children aged 10 or less, surgery was associated with a recurrence rate of 17%, compared with 31% persistence in the nonsurgical group. For children aged 11 and more, surgery was associated with a recurrence rate of 15%, compared with 58% persistence in the nonsurgical group. There was no significant difference between Quick-Disabilities of the Arm, Shoulder, and Hand scores in any group. CONCLUSIONS: In a child with a wrist ganglion, if the cyst ultimately resolved, it usually did so within 18 months. Dorsal ganglion cysts and ganglion cysts in older children have a higher chance of persisting. In children treated with surgical excision, we found a 15% recurrence rate.

Orthopedic Activity in Field Hospitals Following Earthquakes in Nepal and Haiti : Variability in Injuries Encountered and Collaboration with Local Available Resources Drive Optimal Response.

BACKGROUND: Field hospitals have been deployed by the Israel Defense Forces (IDF) Medical Corps in numerous disaster events. Two recent deployments were following earthquakes in Haiti in 2010 and in Nepal in 2015. Despite arrival in similar timetables, the mode of operation was different-independently in Haiti and in collaboration with a local hospital in Nepal. The pathology encountered in the two hospitals and the resultant treatment requirements were significantly different between the two events. The purpose of this study was to analyze these differences and their implications for preparation and planning of future deployments. METHODS: Data were obtained from IDF records and analyzed using SPSS™ software. RESULTS: 1686 patients were treated in Nepal versus 1111 in Haiti. The caseload in Nepal included significantly less earthquake-related injuries (26 vs. 66 %) with 28 % of them sustaining fractures versus 47 % in Haiti. Femoral fractures accounted for 7.9 % of fractures in Nepal versus 26.4 % in Haiti with foot fractures accounting for 23.8 and 6.4 %, respectively. The rate of open fracture was similar at 29.4 % in Nepal and 27.5 % in Haiti. 18.1 % of injured patients in Nepal underwent surgery, and 32.9 % of which was skeletal compared to 32 % surgical cases (58.8 % skeletal) in Haiti. 74.2 % of patients in Nepal and 34.3 % in Haiti were treated for pathology unrelated to the earthquake. CONCLUSIONS: The reasons for the variability in activities between the two hospitals include the magnitude of the disaster, the functionality of the local medical system which was relatively preserved in Nepal and destroyed in Haiti and the mode of operation which was independent in Haiti and collaborative with a functioning local hospital in Nepal. Emergency medical teams (EMTs) may encounter variable caseloads despite similar disaster scenarios. Advance knowledge of the magnitude of the disaster, the functionality of the local medical system, and the collaborative possibilities will help in planning and preparing EMTs to function optimally and appropriately. However, as this information will often be unavailable, EMTs should be capable to adapt to unexpected conditions.

[LESSONS FROM PREPAREDNESS OF HOSPITALS TO SNOWSTORMS].

Snowstorms are not a usual scene in Israel, which normally enjoys relatively warm weather, even in the winter. In the last two years we faced three severe snowstorms that had a major impact on the routine daily life in Israel. Roads were blocked, people experienced long electricity power failures, and secondary to slippery conditions, there was more than a threefold increase of orthopedic injuries. These storms confronted hospitals with unique challenges, both medical and logistic. Hospitals must be prepared to cope with the challenge of maintaining continuation of care. We propose four phases of preparedness strategy: at the beginning of the winter, once there is a weather forecast warning, during the storm itself, and returning to norm. This manuscript deals with the lessons learned by two hospitals in Safed and Jerusalem dealing with snowstorms.

A unique presentation of the rare Nora's lesion, symptomatic bizarre parosteal osteochondromatous proliferation: A case report.

Bizarre parosteal osteochondromatous proliferations, also known as Nora's lesions, are rare benign tumors with a high recurrence rate. They are often difficult to identify because of their similar appearance to other tumors. We describe a 25-year-old healthy female patient with bizarre parosteal osteochondromatous proliferations in an uncommon location on the pelvic ilium, presenting with unique clinical findings of abdominal pain and femoral paresthesia and showing atypical radiographic findings. To the best of our knowledge, this is one of the very few cases ever reported in the literature of Nora's lesion in this particular location and possibly the first case ever with this specific presentation. The lesions' radiographic images, combined orthopedic and general surgery procedures, and histological analysis are detailed. The patient's continued 4-year follow-up has demonstrated no symptoms or evidence of recurrence.

A Multivariate Meta-Analysis for Optimizing Cell Counts When Using the Mechanical Processing of Lipoaspirate for Regenerative Applications.

Lipoaspirate has become the preferred source for regenerative cells. The mechanical processing of lipoaspirate has advantages over enzymatic processing but has a lower yield of regenerative cells. A review of the literature shows different techniques of extraction, but the ideal method or combination has not been determined. METHODS: A comprehensive literature search was focused on the mechanical processing of lipoaspirate, without the use of enzymes. Data from the articles were integrated by utilizing a multivariate meta-analysis approach and used to create a statistical-based predictive model for a combination of multiple variables. RESULTS: Starting with 10,000 titles, 159 articles were reviewed, and 6 met the criteria for inclusion and exclusion. The six studies included data on 117 patients. Sixteen factors were analyzed and six were identified as significant. The predictive profilers indicated that the optimal combination to maximize the cell yield was: a centrifuge force of 2000× g, a centrifuge time of 10 min, a cannula diameter of 2 mm, and an intra-syringe number of passes of 30. The optimal patient factors were a higher BMI and younger age. CONCLUSIONS: The novelty of the method used here was in combining data across different studies to understand the effect of the individual factors and in the optimization of their combination for mechanical lipoaspirate processing.

Early benefits of a secondary fracture prevention programme.

INTRODUCTION: The most successful programme for secondary fracture prevention is the FLS (fracture liaison service) model. Our orthopaedic department carried out a prospective randomised study to measure the effectiveness of a 4-step intervention programme. The findings in this study reveal important additional clinical benefits to having an orthopaedic-based FLS programme and evaluates the usefulness of fracture risk tools. METHODS: We carried out a prospective study to evaluate patients with a fragility fracture of the hip. There were 2 groups, intervention and control (each 100 patients). Of these, 20 were either removed from the study or dropped out, leaving 180 for analysis. In addition to routine preoperative blood tests, albumin and thyroid function levels were obtained and PTH (parathyroid hormone) levels when indicated.The intervention group (83 patients) had a dual-energy x-ray absorptiometry (DEXA) scan performed and fracture risk (FRAX) was calculated. RESULTS: 12 patients (6.7%) had blood results which showed a potentially treatable cause for osteoporosis and 36 (20%) had blood results that changed their medical care.FRAX scores (180 patients) showed that the major osteoporotic fracture score correctly predicted the hip fracture in only 49%. The hip fracture score correctly predicted the hip fracture in 83%.DEXA scores (65 patients) showed osteoporosis in only 46% of hips and in only 26% of spines.An abnormal FRAX score or DEXA scan would have predicted a fragility fracture 93% of the time. CONCLUSIONS: In addition to reducing secondary fractures, FLS programmes can provide fundamental benefits to the health of the patient. The intervention programme in this study identified patients with underlying treatable causes, correctable clinical conditions and patients with an unusually low bone density. When used together, FRAX and DEXA are more sensitive predictors for hip fracture risk than either are individually. TRIAL REGISTRY: 201497CTIL (https://clinicaltrials.gov/ct2/show/NCT02239523).

Achilles tenotomy as an office procedure: safety and efficacy as part of the Ponseti serial casting protocol for clubfoot.

BACKGROUND: Ponseti demonstrated the correction of clubfoot in infants using manipulation followed by the application of well-molded long-leg plaster casts. Percutaneous Achilles tenotomy was recommended to correct residual equinus contracture in approximately 80% of cases. In the current study, we evaluated the safety of this practice for the treatment of clubfoot when performed as an "office procedure" without sedation or general anesthesia during the final stage of the serial casting protocol. PATIENTS AND METHODS: We retrospectively collected data regarding babies who underwent serial manipulation and casting according to the Ponseti protocol for the treatment of clubfoot. All babies managed in the outpatient clinic between 2006 and 2010 were included. Tenotomy was indicated when the forefoot was completely corrected and if the hind-foot showed rigid equinus. Tenotomy was performed by a single scalpel stab in the outpatient clinic, using topical and local anesthesia (without general anesthesia or sedation). The cast was then applied and kept on for 3 weeks. Babies were discharged home after 1 hour of supervision. Surgical reports regarding Achilles tenotomy were reviewed, and data were collected from postoperative notes. We specifically looked for perioperative complications, recovery unit notes, and hospital readmission. RESULTS: Fifty-six babies (83 feet) were included in the current study. There were 40 males and 16 females, and 27 of them had bilateral clubfoot. Three babies (0.5%) had complex (syndrome-related) clubfoot; familial risk was known in 6 (11%) babies. Forty-one (73%) babies were indicated for Achilles tenotomy. Tenotomy was performed after an average of 5 casts (range, 3 to 9). No adverse events were related to local anesthesia and/or the procedure itself, and there was no delay in discharge in any of the operated babies. One baby was evaluated in the emergency room 3 days after the procedure because of (unfounded) parental concern of swelling inside the cast. All other babies had an uneventful course. Retenotomy was performed in 7 babies (12 feet); 2 of them (4 feet) had complex clubfoot. All of these babies (ie, their parents), except 1, had moderate to poor compliance with the treatment protocol. CONCLUSIONS: Tenotomy as an office procedure using topical and local anesthesia is a safe procedure. It does not incur a substantial rate of readmission to the emergency room, either because of parental concern or because of actual complications. The need for retenotomy is related to a low compliance with the treatment protocol. LEVEL OF EVIDENCE: Level II.

Hyaluronic acid injections for chronic tennis elbow.

BACKGROUND: For most patients, tennis elbow (TE) resolves within 6 months of onset. For those with persistent and painful TE, nonsurgical treatment options are limited. Thousands of studies have tried to find effective treatments for TE but have usually failed. In this study, we tested the hypothesis that injections with hyaluronic acid (HA) would be effective at reducing pain from chronic TE. METHODS: Patients with a minimum of six months of pain from TE and with a pain level of 50 or greater (out of 100) were included in the study. They were randomized equally into one of two treatment groups: injection with HA or injection with saline control. Follow-up was conducted at 3, 6 and 12 months from the initial injection. Both the patient and the examiner at the follow-up visits were blinded to the treatment arm. The primary outcome measure was the visual analog scale (VAS pain) score at one year. Additional outcome measures included the shortened Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) and Patient Rated Tennis Elbow Evaluation (PRTEE) scores. RESULTS: Eighteen patients were randomized into the HA injection treatment arm, and 17 (94%) completed the study. The average age was 51.9 years, and 10 of the subjects were male. Patients had an average of 28.1 months of pain before entering the study. The VAS score in the HA group decreased from a baseline of 76.4-14.3 at 12 months. All 17 patients in the HA group showed VAS score reductions above the minimal clinically important difference (MCID) of at least 18. The PRTEE score improved from 67 to 28.1. The QuickDASH score improved from 53.7 to 22.5. Follow-up in the saline group was less than 50% and was therefore not used as a comparator. CONCLUSIONS: HA injections yielded significant success in pain relief by three months. Patients continued to improve for the 12-month duration of the study. This study indicates that patients with chronic lateral epicondylitis may benefit from receiving injections of hyaluronic acid rather than having to undergo surgery.

Osteoid osteoma and osteoblastoma.

Osteoid osteoma and osteoblastoma are commonly seen benign osteogenic bone neoplasms. Both tumors are typically seen in the second decade of life, with a notable predilection in males. Histologically, these tumors resemble each other, with characteristically increased osteoid tissue formation surrounded by vascular fibrous stroma and perilesional sclerosis. However, osteoblastomas are larger than osteoid osteomas, and they exhibit greater osteoid production and vascularity. Clinically, osteoid osteoma most commonly occurs in the long bones (eg, femur, tibia). The lesions cause night pain that is relieved with nonsteroidal anti-inflammatory drugs (NSAIDs). Osteoblastoma is most frequently located in the axial skeleton, and the pain is usually not worse at night and is less likely to be relieved with NSAIDs. Osteoblastoma can be locally aggressive; osteoid osteoma lacks growth potential. Osteoid osteoma may be managed nonsurgically with NSAIDs. When surgery is required, minimally invasive methods (eg, CT-guided excision, radiofrequency ablation) are preferred. Osteoblastoma has a higher rate of recurrence than does osteoid osteoma, and patients must be treated surgically with intralesional curettage or en bloc resection.

Efficacy of orthopaedic-inspired osteoporosis management: a secondary fracture prevention program after a fracture of the hip in a prospective randomized study.

AIMS: Patients who present with fragility fractures are consistently under-evaluated and under-treated for underlying osteoporosis. This point-of-care represents a lost opportunity to prevent future fractures. This 2-arm study evaluated the success by an orthopaedic department in osteoporosis evaluation and initiating treatment. METHODS: Patients over the age of 50 years with a fragility fracture of the hip were candidates for inclusion. Exclusion criteria included end-of-life care and moderate or severe dementia. Patients were prospectively randomized into 1 of 2 groups. The Letter group received a letter at the time of discharge encouraging their primary care physician to start medication for osteoporosis (Letter group). The intervention group had 4 interventions including printed information, a DEXA scan, a specific treatment recommendation, and monthly phone calls for 4 months (Intervention group). The primary outcome measure was whether the patient was on recommended treatment at 4 months from the fracture. RESULTS: There were 200 patients in the study, 100 in the Letter, and 100 in the Intervention group. Sixteen patients were removed from the study since they either died (9) within 4 months of their fracture, were transferred for end-of-life care (7), and 4 dropped out. This left 180 patients for analysis. The Letter group had only 6 patients (6.2%) on recommended treatment compared with the Intervention group with 64 patients (77.1%). This was statistically significant (P < 0.0001). CONCLUSION: Osteoporosis is a worldwide epidemic. Internationally, only about 20% of patients after a hip fracture are treated for their underlying weak bone. The most effective systems use a fracture liaison service (FLS) model. We present a 4-part intervention program that uses an FLS coordinator within the orthopaedic department. We encourage orthopaedic programs to adopt this or other models with the goal of taking the first step toward responsibility for bone health.An FLS program within an orthopaedic department can successfully initiate treatment for underlying osteoporosis.

CT-guided radiofrequency ablation of pediatric osteoid osteoma utilizing a water-cooled tip.

BACKGROUND: Radiofrequency ablation (RFA) has a success rate of 70% to 90% in the treatment of osteoid osteoma (OO). Failures are due to malpositioning of probes or incomplete ablation, possibly related to conventional probes' small heating diameter (range, .5-.8 cm). Cooled-tip probes have a larger heating distance, ablating up to 3 cm, affecting a larger volume, and improving success rate in adults. Concerns regarding damage to surrounding structures and unknown effects on bony growth potential have delayed the widespread use of cooled tips in children. Our goal was to examine whether this technique, when added to conventional RFA, improves the clinical results and whether it carries any additional risks to children. METHODS: A total of 22 patients with OO, 15 boys and 7 girls aged 3.5 to 18 years, were treated with the Cool-tip Tyco probe (Valleylab, Boulder, CO). Fifteen lesions were located in the femur, two in the tibia, and the remainder in the humerus, talus, calcaneus, second metatarsus, and sacrum. The OO was intra-articular in five patients: three in the femur, and one each in the calcaneus and talus. Average postoperative follow-up was 38.5 (range, 16-66) months. RESULTS: The symptoms of all but one patient resolved immediately after a single RFA treatment. One patient experienced partial relief and underwent a second successful ablation. One patient experienced recurrence of disease after 18 months, and one superficial infection occurred. No fractures, neurovascular complications, or growth disturbances were found. CONCLUSIONS: The cooled-tip probe is highly effective and safe for the treatment of pediatric osteoid osteoma, with no adverse events in this age group.

Posttraumatic painful hip: sonography as a screening test for occult hip fractures.

OBJECTIVE: Nondisplaced hip fractures may be radiographically occult and require magnetic resonance imaging (MRI) or bone scintigraphy for diagnosis. Both examinations are expensive and are not readily available in many hospitals. Our objective was to evaluate sonography as a screening tool for occult hip fractures in posttraumatic painful hips in elderly patients. METHODS: We prospectively evaluated 30 patients (mean age, 73 years), who were admitted for painful hips after having low-energy trauma with nondiagnostic hip radiographs. After inclusion, patients underwent sonography of both hips for signs of injury. After completion of the sonographic examination and analysis of the results, patients underwent MRI of both hips. The sonographic findings were compared with the MRI findings, which served as the reference standard for accurate detection of a hip fracture. RESULTS: Ten hip fractures were diagnosed by MRI. Sonography showed trauma-related changes in all of those patients and in 7 additional patients, 3 of whom had pubic fractures. Sonography correctly identified 13 patients without hip fractures. The sensitivity of sonography was found to be 100%, whereas the specificity for hip fractures was 65%. CONCLUSIONS: Sonography for posttraumatic hip pain with negative radiographic findings did not result in a single missed hip fracture. Therefore, sonography may serve as an effective screening tool, mandating MRI only for cases with positive findings, whereas patients with negative sonographic findings need no further investigation. Sonography may therefore be very useful in hospitals around the world, where MRI may not be readily affordable or available.

Chondromyxoid fibroma of the distal fibula treated by percutaneous radiofrequency ablation.

BACKGROUND: Percutaneous radiofrequency ablation (RFA) has been shown to be an effective treatment for soft tissue lesions and also benign bone tumors, especially osteoid osteoma. There are limited data regarding this technique in other bone tumors, specifically larger and more aggressive ones. PURPOSES: To describe the use of RFA as a definitive treatment and an alternative to traditional open surgery for the treatment of chondromyxoid fibroma (CMF), a benign but locally aggressive bone tumor. CASE PRESENTATION: An 11.5-year-old girl was diagnosed with a 4-cm lytic bone lesion of the distal fibula. Evaluation, including biopsy, revealed CMF. It was managed by fluoroscopy-guided RFA only. Six-year follow-up demonstrated complete healing without damage to the adjacent distal fibular growth plate. DISCUSSION AND CONCLUSIONS: RFA induces local heat in the ablation field and causes tissue necrosis. The depth of heat penetration and the size of heated sphere are accurately controlled by modern types of ablation probes and accurate positioning. The current report demonstrates the ability to use this percutaneous technique for larger and more aggressive bone tumors than has been indicated previously.

Computerized navigation for the internal fixation of femoral neck fractures.

BACKGROUND: Accurate placement of cannulated screws is essential to ensure secure fixation of femoral neck fractures. We compared computerized navigation and conventional fluoroscopy with regard to the accuracy of screw placement for the fixation of femoral neck fractures. METHODS: We retrospectively compared two groups of twenty consecutive patients with a femoral neck fracture who underwent internal fixation with three cannulated screws. Computer-based navigation was used to guide screw placement in one group, and conventional fluoroscopy was used in the other group. Radiographic evaluation included the measurement of screw parallelism and spread, the calibrated distance from the lesser trochanter, and joint penetration. The follow-up period was two years. The rates of complications in both groups were evaluated. RESULTS: The navigation-assisted group had better screw parallelism and greater spread of the screws. There was a tendency for fewer reoperations and significantly fewer overall complications in the patients in whom computerized navigation was used (p < 0.018). CONCLUSIONS: Computerized navigation improves the accuracy of cannulated screw placement in the internal fixation of femoral neck fractures. It may provide better mechanical stability and improved fracture outcome.

Shrapnel management.

With the increased incidence of terrorism worldwide, it is important for surgeons to understand the role of shrapnel injury in mass casualty events. Several diagnostic modalities are available, including plain radiography, computed tomography, ultrasound, angiography, and computerized surgical navigation based on real-time acquisition of fluoroscopic data. Shrapnel management techniques are selected based on the following chronologic phases: acute, subacute, and late.

Talc sclerodhesis of persistent Morel-Lavallée lesions (posttraumatic pseudocysts): case report of 4 patients.

Large posttraumatic pseudocysts are infamous for their tendency to recur despite repeated aspiration. The standard practice has been repeated extensive surgical debridement. To avoid the need for such treatment, talc was used to sclerose the lesion in 4 patients treated between 2000 and 2003. The patients were between the ages of 20 and 73 and had thigh and buttock pseudocysts that persisted for an average of 3 months. Talc was administered under fluoroscopic guidance and suction drainage (wall suction followed by a bulb vacuum drainage system) was applied for an average of 12 days. The patients were followed for an average period of 27 months after talc sclerodhesis. All persistent pseudocysts showed an immediate cessation of fluid accumulation in the treated space without reccurence. One case which was complicated by infection, had to be treated twice with talc to cease the accumulation. In this case, the infection recurred, although fluid accumulation did not recur. Talc sclerodhesis proved to be a simple and rapid method of treatment in posttraumatic cases classically treated by repeated and aggressive surgical methods.
