RESUMO
The timing of definitive fixation of open ankle malleolar fractures is still controversial. This study intended to evaluate the outcome of patients who were managed by immediate definitive fixation in comparison to delayed definitive fixation following open ankle malleolar fractures. This was an IRB approved retrospective case control study of 32 patients who were treated with open reduction and internal fixation (ORIF) for open ankle malleolar fractures at our Level I trauma center 2011-2018. Patients were divided into 2 groups; immediate ORIF group (within 24 hours) and delayed ORIF group (first stage included debridement and external fixator or splinting followed by second stage of delayed ORIF). Outcomes assessed were postoperative complications (wound healing, infection, nonunion). Logistic regression models were used to access the unadjusted and adjusted associations between post- operative complications and selected co factors. The immediate definitive fixation group included 22 patients while the delayed staged fixation group included 10 patients. Gustilo type II and III open fractures were associated with higher complications rate (p-value = 0.012) in both groups. Comparing the 2 groups, There was no increase in complication in the immediate fixation group compared to the delayed group. Complications following open ankle malleolar fractures are usually associated with Gustilo type II and III open fractures. Immediate definitive fixation after adequate debridement was not found to increase complication rate compared to staged management.

Open reduction internal fixation is the gold standard for unstable ankle fracture fixation; however, complications in patients with multiple medical comorbidities are common. Intramedullary nail fixation of the fibula can help to mitigate these difficulties. A retrospective chart review was performed on all patients who underwent fixation for unstable ankle fracture between January 2015 and March 2016 at our level I trauma center. Comorbidities in the patient sample included were one or several of diabetes, renal disease, hypertension, advanced age with osteoporosis, hemorrhagic blisters, and alcoholism. The primary outcomes studied were wound complications, infections, and hardware failure or failure of fixation. Eighteen patients with a mean age of 61 years underwent fibular intramedullary nail fixation, all of whom were considered at high risk for postoperative complications. Patients presented with Weber B or C fracture patterns. All patients had syndesmotic fixation through the nail by one or two 3.5-mm tricortical screws. A medial malleolus was added if needed for stability. The average follow-up time was 291.1 (range 9 to 14 months) days. The prescribed range of time to weightbearing was 2 to 6 weeks. All patients maintained reduction of the fracture and had no wound complications. No syndesmotic screws broke postoperatively, although most patients to failed comply with the postoperative non-weightbearing restrictions. Intramedullary nailing of the fibula with syndesmotic intranail fixation is minimally invasive, quick, and provides adequate fixation strength. It offers a viable treatment option for patients at high risk for complications or who are suspected to have difficulty with follow-up or compliance.

BACKGROUND: Deltoid ligament injuries are typically caused by supination-external rotation or pronation injury. Numerous ligament reconstruction techniques have been proposed; however, clear indications for operative repair have not yet been well established in the literature. METHODS: We reviewed primary research articles comparing ORIF treatment for ankle fracture with versus without deltoid ligament repair. RESULTS: Five studies were identified with a total of 281 patients. 137 patients underwent ORIF with deltoid repair, while 144 patients underwent ORIF without deltoid ligament repair. Clinical, radiographic, and functional outcomes, as well as complications were considered. The average follow-up was 31 months (range, 5-120). CONCLUSIONS: Current literature does not provide clear indication for repair of the deltoid ligament at the time of ankle fracture repair. There may be some advantages of adding deltoid ligament repair for patients with high fibular fractures or in patients with concomitant syndesmotic fixation. LEVEL OF CLINICAL EVIDENCE: III.

PURPOSE: Supracondylar fractures in the pediatric population are common. For years, K-wires have been the preferred method of surgical fixation. However, fixation with K-wires alone may lead to multiple complications. This study reports the results of surgical care of supracondylar humerus fractures using screw fixation with K-wires or screw fixation alone. METHODS: This study retrospectively reviewed all patients with supracondylar humerus fractures treated with screw fixation between 2007 and 2013. Patients treated only with smooth wires, or having a displaced medial epicondyle, or presenting with lateral condyle fractures were excluded from the study. Flynn's criteria were used to determine the outcome. RESULTS: Seventeen patients who met inclusion criteria formed the study group. All patients were followed until union, resolution of complications, and return to preinjury activity level. Satisfactory outcome was reported in 70.6% of patients with less than 15° loss of either flexion or extension. Mean time to union was 6.5 weeks (range 3.3-12.1 weeks). Screw fixation alone had a shorter mean time to union (5.5 weeks) than compared screw fixation with K-wires group (6.9 weeks). Full range of motion following surgical invention was associated with Flynn's criteria (p value = 0.044). CONCLUSION: Screw fixation for pediatric supracondylar fractures is a viable option to achieve healing and early motion in highly unstable fractures as well as fractures which require (1) increased stability, (2) maintenance of stability during wound checks in the immediate postoperative period and after discontinuation of the cast, or (3) if further exploration like associated vascular injury is warranted.

BACKGROUND: Acute compartment syndrome (ACS) is often associated with tibial plateau fractures and is a limb-threatening injury. Staged management through fasciotomy with delayed definitive fixation can prevent muscle necrosis and increase limb salvage rates. This procedure opens a large area for potential contamination and infection in the lower extremity. Recent studies have shown an increased risk of infection following fasciotomy and staged management for tibial plateau fractures. This study reports the rate of infection, delayed union, and nonunion in patients with this injury pattern. METHODS: This study was a retrospective chart review, which received institutional review board approval. It surveyed patient radiographs, clinical notes, and operating room reports from a level I trauma center between 2010 through 2016. RESULTS: The results demonstrated that 23 out of 221 consecutive patients with ACS of the lower extremity presented with tibial plateau fracture over a 65-month period. Of these 23 patients, four were lost to follow-up or died. Nineteen patient charts were surveyed, 63% were male (12/19) and 37% were female (7/19). One patient developed deep infection (5.3%). Three patients experienced delayed union (15.8%), and their fractures eventually achieved union without intervention. The mean time to union was 14 weeks. Schatzker type V/VI fractures were the most prevalent type of fractures seen among patients. CONCLUSION: The infection rate found is lower than in other recently published studies. The incidence of delayed union or nonunion of the fracture was also lower than in other publications in the literature. Early decompression through double- or single-incision fasciotomy does not increase the risk of infection or nonunion of the fracture. The delayed union rates found in this study are lower than those in previous studies. LEVEL OF EVIDENCE: Level IV prognostic.

BACKGROUND: Lower extremity angular deformities are common in children with skeletal dysplasia and can be treated with various surgical options. Both acute correction by osteotomy with internal fixation and gradual correction by external fixation have been used with acceptable results. Recently, the Guided Growth concept using temporary hemiepiphysiodesis for correction of angular deformities in the growing child has been proposed. This study presents the results of temporary hemiepiphysiodesis using eight-Plates and medial malleolus transphyseal screws in children with skeletal dysplasia with lower extremity angular deformities. METHODS: Twenty-nine patients (50 lower extremities) with skeletal dysplasia of different types were treated for varus or valgus deformities at 2 centers. The mean age at the time of hemiepiphysiodesis was 10±2.9 years. A total of 66 eight-Plates and 12 medial malleolus screws were used. The average follow-up time between the index surgery and the latest follow-up with the eight-Plate in was 25±13.4 months. Erect long-standing anteroposterior and lateral view radiographs were obtained for deformity planning before the procedure. Angular deformities on radiograph were evaluated by mechanical axis deviation, mechanical lateral distal femoral angle, medial proximal tibial angle, and lateral distal tibial angle. Mechanical axis deviation was also expressed as a percentage to one half of the width of the tibial plateau, and the magnitude of the deformity was classified by determining the zones through which the mechanical axis of the lower extremity passed. Four zones were determined on both the medial and lateral side of the knee and the zones were labeled 1, 2, 3, and 4, corresponding to the severity of the deformity. A positive value was assigned for valgus alignment and a negative for varus alignment. RESULTS: Patients were analyzed in valgus and varus groups. There was correction in 34 of 38 valgus legs and 7 of 12 varus legs. In the valgus group, the mean preoperative and postoperative mechanical lateral distal femoral angles were 82.1±3.7 and 91.1±4.9 degrees, respectively (P<0.001). The mean preoperative and postoperative medial proximal tibial angles were 98.5±8 and 87.8±7.1 degrees, respectively (P<0.001). Six patients with bilateral ankle valgus deformities (12 ankles) underwent single-screw medial malleolus hemiepiphysiodesis. The mean preoperative and postoperative lateral distal tibial angles were 73.9±8.7 and 86.1±6.8 degrees, respectively (P<0.001). The numbers of plates in each anatomic location were not enough to make statistical conclusions in varus legs. Four patients in the valgus group and 3 patients in the varus group did not benefit from the procedure. Mechanical axes were in zone 2 or over in 94% of the legs preoperatively, whereas postoperatively, only 23% of the legs had mechanical axes in zone 2 or over in varus and valgus groups. CONCLUSIONS: Growth modulation with an eight-Plate is a relatively simple surgery and has low risk of mechanical failure or physeal damage. It can be performed in very young patients, which is an important advantage in skeletal dysplasia. Screw purchase is reliable even in the abnormal epiphysis and metaphysis. Our results show that Guided Growth using eight-Plates in skeletal dysplasia is safe and effective. LEVEL OF EVIDENCE: Level IV.

Open midfoot wedge osteotomy correction can cause neurovascular compromise, requires extensive exposure, sacrifices normal joints, and shortens the foot. We used a minimally invasive technique to treat complex foot deformities by combining percutaneous Gigli saw midfoot osteotomy, circular external fixation, and acute, gradual, or gradual with acute manipulation correction. The medical records of 23 patients (26 feet) with complex foot deformities (congenital, 18 feet; neuromuscular, 4 feet; post-traumatic, 3 feet; malunion, 1 foot) who had undergone treatment within an 18-year period (1990 through 2007) were retrospectively reviewed. We also performed the procedure on 10 cadaveric limbs to determine whether anatomic structures were at risk. Correction was achieved in all feet. The mean duration of external fixation treatment was 4.2 (range 3 to 7) months. The mean follow-up duration was 4.7 (range 2 to 18) years. A significant difference was observed in the pre- and postoperative, lateral view, talar-first metatarsal angle (p = .001). Minor complications (4 feet) consisted of bony exostoses. Major complications included recurrent deformity in 3 feet and sural nerve entrapment in 1 foot. Two patients had mild and one moderate foot pain. Three patients had impaired gait function; the remaining patients had functional gait. The mean interval until wearing regular shoes after external fixation removal was 2.3 (range 1 to 4) months. All but 1 of the patients were satisfied with the final results. We observed no cadaveric neurovascular injury. Our results have shown that percutaneous Gigli saw midfoot osteotomy can be performed without neurovascular injury and is capable of successfully correcting complex foot deformities.

A 14-year-old male patient was successfully treated with the reamer irrigator aspirator for femur intramedullary rod preparation after sustaining right and left closed femur fractures because of an all-terrain vehicle accident. In patients already categorized as high risk for fat embolism syndrome, such as those with bilateral femur fractures, reaming both femora greatly increases the likelihood of this complication. The reamer irrigator aspirator provides an effective tool that potentially mitigates the risk of fat embolism syndrome in pediatric patients with this type of orthopedic trauma.
RESUMO
Background: Supracondylar humerus (SCH) fractures are some of the most common fractures in pediatric patients with surgery typically consisting of either open or closed reduction with internal fixation. The aim of this meta-analysis was to identify patient, injury, and administrative factors that are associated with treating pediatric SCH fractures with open techniques. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, PubMed and CINAHL database searches were conducted for studies from 2010 to 2023 that made direct comparisons between open reduction and internal fixation (ORIF) and closed reduction and percutaneous pinning (CRPP) for treating SCH fractures in the pediatric population. The search terms used were "pediatric" AND "SCH fracture" OR "distal humerus fracture." Screening, quality assessment, and data extraction were performed by 4 reviewers. After testing for heterogeneity between studies, data were aggregated using random-effects model analysis. Results: Forty-nine clinical studies were included in the meta-analysis. Summated, there were 94,415 patients: 11,329 treated with ORIF and 83,086 treated with CRPP. Factors that were significantly associated with greater rates of ORIF included obesity (p = 0.001), Gartland type IV fractures (p < 0.001), general neurological deficits (p = 0.019), and ulnar nerve deficits (p = 0.003). Gartland type II (p = 0.033) and medially displaced fractures (p = 0.011) were significantly associated with lower rates of ORIF. Secondary analysis showed cross-pinning constructs (p = 0.033) and longer hospital stays (p = 0.005) are more likely to be observed in patients undergoing ORIF compared with CRPP. Conclusion: This meta-analysis demonstrates that factors such as obesity, fracture displacement, and concomitant nerve deficits are more likely to require ORIF as opposed to CRPP. Level of Evidence: Therapeutic Level III.
RESUMO
The purpose of this study was to determine if short-term outcomes differed for pediatric patients with suspected musculoskeletal infection with or without a preoperative MRI. This was a multicenter, retrospective review of patients aged 0-16 years who presented with atraumatic extremity pain, underwent irrigation and debridement (I&D), and received at least one preoperative or postoperative MRI over a 10-year period. Primary outcomes were time to OR, total I&Ds, readmission rate, time from OR to discharge, and total number of MRIs. Secondary outcomes entailed the rate at which concurrent osteomyelitis was identified in patients with septic arthritis and the extent of the resulting surgical debridement. Of the 104 patients, 72.1% had a preoperative MRI. Patients with a preoperative MRI were significantly less likely to have surgery on the day of admission. No difference was found between groups regarding total I&Ds, readmission rate, time from OR to discharge, and total number of MRIs. Of the 57 patients diagnosed with septic arthritis, those with a preoperative MRI were significantly more likely to have concurrent osteomyelitis identified and to undergo bony debridement in addition to arthrotomy of the joint. In conclusion, patient outcomes are not adversely affected by obtaining a preoperative MRI despite the delay in time to OR. Although preoperative MRI can be beneficial in ruling out other pathologies and identifying the extent of concurrent osteomyelitis, the decision to obtain a preoperative MRI and timing of surgery should be left to the discretion of the treating surgeon.
RESUMO
BACKGROUND: Obstetrical brachial plexus palsy (OBPP) is a relatively common stretch injury of the brachial plexus sustained during delivery. Tendon transfers are commonly performed to improve shoulder function among patients with OBPP. Although several techniques for the surgical management of OBPP exist, it is unclear whether tendon transfers to the rotator cuff vs. posterior humerus yield different outcomes. METHODS: A systematic search in PubMed, Web of Science, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and Google Scholar up to January 1, 2021, was performed. Relevant publications were classified by surgical technique of tendon transfers to the rotator cuff or posterior humerus. The standard mean difference (SMD) and 95% confidence intervals were calculated to compare preoperative and postoperative aggregate Mallet scores as well as abduction and external rotation scores using the Mallet scale. A p value of <0.01 was considered significant. RESULTS: Data from 26 studies and 951 patients (46.2% male patients) with a mean age of 68.9 ± 29.3 months were included. Eight hundred three patients underwent tendon transfer to the rotator cuff and 148 to the posterior humerus. The average postoperative follow-up period was 45.2 ± 21.7 months. The pooled cohort had an overall improvement in postoperative aggregate Mallet scores (SMD = 5.53, p < 0.001), abduction scores (SMD = 1.79, p < 0.001), and external rotation scores (SMD = 1.99, p < 0.001). Tendon transfer to the rotator cuff had a greater postoperative improvement in abduction (SMD = 1.90, p < 0.001) than transfer to the posterior humerus (SMD = 1.32, p < 0.001) while both techniques yielded similar improvements in external rotation (rotator cuff SMD = 2.01, p < 0.001, posterior humerus SMD = 1.98, p < 0.001). CONCLUSION: This is the first systematic review comparing outcomes for tendon transfers to the rotator cuff vs. the posterior humerus for improving shoulder function in patients with OBPP. Overall, tendon transfers are an effective treatment for improving shoulder function. Transfer of the latissimus dorsi and teres major to the rotator cuff compared with transfer to the posterior humerus results in greater improvement in abduction while both techniques have similar results in improving external rotation. LEVEL OF EVIDENCE: Level I Systematic review of Level I and Level II studies.

Prostate adenocarcinoma metastasizes to bone and forms fragile blastic lesions, which can present as dense obstacles intraoperatively. There are limited reports on the challenges surgeons face when operating through these lesions. A 60-year-old male with a pathologic subtrochanteric femur fracture in the presence of blastic lesions was successfully treated with intramedullary (IM) fixation. Pathologic fractures from blastic bone lesions are expected to increase in prevalence as survivability improves for metastatic prostate cancer. Orthopedic surgeons, when performing IM fixation for these fractures, should be prepared to utilize accessory equipment and should adopt creative techniques for reduction and fixation.
RESUMO
Fractures involving the distal radius metaphyseal-diaphyseal junction (MDJ) present a unique challenge for pediatric orthopedic surgeons. These fractures are too proximal for percutaneous K -wire fixation and too distal for retrograde flexible nailing. The purpose of this study was to: (1) determine the safety of a described antegrade approach from the posterior interosseous nerve (PIN); (2) assess the efficacy of antegrade nailing in cases of distal MDJ fractures; and (3) describe a standardized lateral approach to the proximal radius. A cadaveric study was performed using 10 adult forearms. Anterograde flexinail was introduced at the proximal radius based on the described "safe zone". Distal MDJ fractures were created using osteotomes. We evaluated the distance between the entry point to the PIN in addition to the quality of the reduction for the fracture. The average distance between the entry point and piercing instrument to the PIN was 5.4 cm (range: 4.7 to 6.0 cm). When grouped based on sex, the average distance was significantly further for males (5.8 cm, range: 5.2 to 6.0 cm) versus females (4.9 cm, range: 4.7 to 5.2 cm), P =0.004. Fracture reduction was not maintained after the introduction of the antegrade flexible nail across the fracture site. For all specimens, >25% displacement was seen on the anterior-posterior imaging. Our modified lateral approach to the starting point in the proximal radius is safe as long as the entry point for antegrade flexible nailing stays proximal to the radial tuberosity during the lateral approach to the proximal radius while the elbow is flexed and the forearm pronated.

CASE: Three male patients, 8-, 13-, and 18-year-old, all developed posttraumatic cubitus varus elbow deformity after distal humerus supracondylar fractures. Each underwent a distal humerus osteotomy with application of a hexapod external fixator to gradually correct the deformity. CONCLUSION: In patients with cubitus varus malunion, the stability of the hexapod external fixation, percutaneous nature of the osteotomy, and availability of running a residual computer-assisted program provides a consistent technique for deformity correction.
RESUMO
INTRODUCTION: Inclusion-body hepatitis (IBH) and hydropericardium syndrome (HPS) are highly infectious diseases caused by fowl adenoviruses (FAdVs). IBH and HPS cause major economic losses in poultry production. IBH is caused by multiple FAdV serotypes such as FAdV-11, FAdV8a, and FAdV8b; while HPS is mainly caused by the FAdV-4 serotype. In 2018, we detected FAdVs in West Bank - Palestine for the first time. This study aims to monitor the emergence of new FAdVs in broiler farms in Gaza Strip-Palestine in 2022. METHODOLOGY: The clinical signs, necropsy, and histopathological findings associated with IBH in the suspected birds were recorded. Polymerase chain reaction (PCR) was performed using primers matching the virus-encoded L1 loop of the hexon gene. The sequences of the L1 loop were analyzed and a phylogenetic tree was constructed and compared with the related FAdV field isolates and reference strains from different regions of the world available in GenBank. RESULTS: The infected broiler displayed FAdVs-induced clinical symptoms and pathological lesions with mortality rates ranging from 20-46%. The L1 loop sequences from the infected flocks were submitted to GenBank with accession numbers ON638995, ON872150, and ON872151. The identified L1 loop gene has high nucleotide homology (96.7-97.9%) to the highly pathogenic FAdV E serotype 8b strain FAdV_isolate_04-53357-122_Canada_2007 (GenBank: EF685489) and 94.5-94.6% to FAdV_10_Belgium_2010 isolate 11-15941 (GenBank: AF339924.1). Furthermore, the phylogenetic analysis indicated that they belong to FAdV-E serotype 8b. CONCLUSIONS: Our study reports the emergence of FAdV-E causing IBH disease in broiler chickens for the first time in Gaza in Palestine.

Purpose: A subcostal flank incision is required for open radical nephrectomy, which is a surgical procedure used to remove tumors of the kidney that are malignant. The erector spinae plane block (ESPB) and continuous catheter use in children are receiving more and more support by paediatric regional anaesthesiologists. Our objective was to compare systemic analgesic to continuous ESPB for pain relief in paediatric patients undergoing open radical nephrectomy. Methods: Sixty children with cancer ASA I or II and undergoing open radical nephrectomy between the ages of two and seven participated in this prospective, randomized, controlled, and open label study. The cases were divided into two equal groups (E and T groups); Group E received ipsilateral continuous ultrasound-guided ESPB at T9 (thoracic vertebrae), with a bolus of 0.4 mL/kg bupivacaine 0.25%. Immediately postoperatively, Group E (ESPB group) received continuous ESPB with a PCA (patient controlled analgesia) pump at a rate of 0.2 mL/kg/hour bupivacaine 0.125%. Group T (Tramadol group), Tramadol hydrochloride was administered intravenously at a dose of 2 mg/kg/8hour, which could be increased to 2 mg/kg/6hours. Then, we followed up on patients' total analgesic consumption for 48 hours following surgery, as well as the time it took for them to request rescue analgesic, their FLACC and sedation scores, and their hemodynamics and side effects immediately following surgery as well as at 2, 4, 6, 8, 12, 18, 24, 36, and 48 hours. Results: A highly significant difference in total tramadol consumed in group T 11.97 ± 1.13 mg/kg while group E was 2.07± 1.54 mg/kg (p < 0.001). 100% patients in group T requested analgesia compared to 46.7% patients in group E (p < 0.001). From 2 to 48 hour, FLACC significantly decreased in E compared to T group (p≤ 0.006) at all-time points. Conclusion: Ultrasound-guided continuous ESPB significantly provided better postoperative pain relief, reduced postoperative tramadol consumption and reduced pain scores compared with the use of tramadol alone, in paediatric cancer patients undergoing nephrectomy.
RESUMO
Background and Aim: Colistin is used to treat avian pathogenic Escherichia coli (APEC), a microorganism that affects turkey meat production in the Gaza Strip and worldwide. However, the recent emergence of plasmid-borne mobile colistin resistance (mcr) genes in pathogenic E. coli strains is a serious antimicrobial resistance (AMR) challenge for both human and animal health. In December 2018, colistin was banned as a veterinary antimicrobial in the Gaza Strip. This study aimed to detect and track the prevalence of colistin-resistant APEC isolated from turkey flocks in the Gaza Strip. Materials and Methods: This study investigated 239 APEC isolates from turkey flocks in the Gaza Strip between October 2018 and December 2021 (at 6-month intervals). The colistin-resistant APEC strains were detected using the broth microdilution method. The mcr-1 gene was identified using a polymerase chain reaction. Results: The overall colistin resistance among the isolated APECs was 32.2% during the study period. The average resistance in the first interval was 37.5%, which significantly decreased to 9.3% in the last interval. Among the 77 phenotypically resistant isolates, 32.4% were positive for mcr-1. The average abundance of mcr-1 in the first interval was 66.6%, which decreased to 25% in the last interval. Conclusion: To the best of our knowledge, this is the first study reporting the presence of the mcr-1 gene among the APEC isolates from turkeys in the Gaza Strip. Banned veterinary use of colistin significantly decreased the percentage of resistant APEC isolates from turkeys in Gaza Strip. Further studies are needed to investigate other colistin resistance genes and track the emergence of AMR.
RESUMO
INTRODUCTION: The US Department of Homeland Security has reported increases in encounters and apprehensions at the US Southwest border for the past several years. The purposes of this study were to assess the demographics, patterns of injuries, and surgical interventions, associated with falls from height along the US-Mexico border. METHODS: A prospective cohort study was conducted at a Level I trauma center from January 2016 through December 2021 of all patients who fell from height crossing the US-Mexico border and presented with injuries requiring admission. RESULTS: A total of 448 patients were admitted with a median age of 30 years (interquartile range [IQR] 16, range 6 to 65). Monthly frequency of admissions increased markedly with a median of 18.5 (IQR 5.3) in 2021. Patients presented with limited health data, and comorbidities were identified in 111 patients (24.7%). Median height fallen was 5.5 m (18 ft). Patients sustaining a fall from ≥ 5.5 m were markedly more likely to have an Injury Severity Score (ISS) of > 15. Median length of stay was 9 days (IQR 11). There were a total of 1,066 injuries with 723 extremity and pelvic; 236 spine; and 107 head or neck, face, thorax, or abdominal injuries. Median ISS was 9.0 (IQR 7, range 1 to 75, 33% > 15). Tibial plafond fracture and spine injury were markedly associated with longer lengths of stay and ISS > 15. All injuries resulted in 635 separate surgical events and 930 procedures. Clinical follow-up occurred in 55 patients (12.2%), with median duration of 28 days (range 6 days to 8 months). DISCUSSION: Injuries associated with border crossings and falls from height were serious and increased in frequency. As the US policy on border security evolves, surgeons in these regions should be prepared to handle the associated injuries and sequelae. Prevention of these serious and debilitating injuries should be undertaken to decrease the burden of disease.

INTRODUCTION: Hand masses are fairly common. While most of these masses are either ganglion cysts or benign tumors, masses in the first web space are not rare, and they may in fact represent a variety of lesions. These include both benign and malignant tumors, metastases, or congenital and anomalous structures, and may involve nerves, vascular structures, connective tissue, and joints. METHODS: In this retrospective case series, data on 12 cases of first dorsal web space hand mass treated at our center over a period of five years were collected and analyzed. RESULTS: Twelve consecutive patients presenting with a first dorsal web space hand mass over a period of five years were reviewed. This represented a group of nine females and three males, with a mean age of 53 years (range = 16-70 years). Seven patients had a mass on the right side and five on the left side. The surgical approach to resect the mass in all 12 patients was dorsal. The most common diagnosis was ganglion cyst (50%), followed by lipoma (25%) and aneurysm (16.6%). There was one case of eccrine spiradenoma. CONCLUSION: First dorsal web space hand masses can encompass multiple different pathologies, and the first web space has an intricate anatomy. Both of these factors mandate a careful approach that includes meticulous preoperative planning with appropriate advanced imaging studies, which helps to make the surgical procedure more efficient and accurate.
RESUMO
PURPOSE: This retrospective review follows 31 tibial nonunions to compare union at the docking site using closed versus open strategies. In this cohort of patients, all but five were infected nonunions. METHODS: Thirteen patients initially treated with single compression were compared with 18 patients treated by open revision of the docking site. In the single compression group, an average of 6.5 cm of bone was resected and index lengthening was 2.04. In the open revision group, a mean of 9.4 cm was resected and the index lengthening was 1.73. RESULTS: Consolidation at the docking site occurred in all subjects in both groups. There was no statistical difference between the two groups. Conclusive evidence of superiority of one modality of treatment over the other cannot be drawn from our data. CONCLUSIONS: The simple compression procedure requires less invasive surgery and is probably less demanding and more cost-effective in short transports.
