RESUMO
BACKGROUND: Gunshots and bomb blasts are important causes of extremity injuries in conflict zones, yet little research exists on the characteristics and outcomes of these injuries in civilian populations. METHODS: We performed a prospective cohort analysis utilizing data from a randomized trial conducted at two civilian hospitals in Jordan and Iraq in 2015-2019. Adults who presented ≤72 h of sustaining an extremity injury were included. We used mechanism of injury (gunshot/bomb blast) as the exposure and wound closure by day 5 as the primary outcome measure. RESULTS: The population predominantly comprised young men (n = 163, 94% male, and median age 29 years) injured by gunshots (61%) or bomb blasts (39%). Compared with the gunshot group, more participants in the bomb blast group had concomitant injuries (32/63 [51%] vs. 11/100 [11%], p < 0.001) and vascular injuries (9/63 [14%] vs. 4/100 [4%], p = 0.02). The wounds were larger in the bomb blast group compared with the gunshot group (median area 86 cm2 [IQR 24-161] vs. 21 cm2 [IQR 7-57], p < 0.001). Compared with the bomb blast group, significantly more participants in the gunshot group achieved wound closure by day 5 (74/100 [74%] vs. 16/63 [25%], p < 0.001). This difference remained after controlling for confounding factors (odds ratio 4.7, 95% confidence interval 1.6-13.7). CONCLUSIONS: In civilians with conflict-related extremity injuries, bomb blast wounds had a lower likelihood of achieving closure within 5 days than gunshot wounds, independent of other factors, such as wound size and vascular injuries.

The study aimed to identify athlete-reported reasons for not returning to pre-injury sports level after anterior cruciate ligament reconstruction (ACLR) and to identify the factors associated with these reasons. Ninety-one athletes with 2 years post-ACLR indicated whether or not they had returned to their pre-injury sport level (same frequency, duration, and intensity). Athletes who did not return were asked to provide the reasons. Athletes' characteristics and injury-related factors were used to determine factors associated with the reasons for not returning. Only nine athletes (10%) returned to pre-injury sport level after ACLR. The most common reasons for not returning were lack of confidence or concerns about re-injury (48.8%), followed by continued post-surgical impairments in the reconstructed knee (39%). Having episodes of the knee giving way after ACLR was the only significant predictor of post-surgical impairments (48.8%; OR=8.3, 95%CI=2.48-27.42, p=0.001). Lack of confidence, concerns about re-injury, or post-surgical impairments in the reconstructed knee were the most frequently reported reasons for not returning to pre-injury sports level with 2 years post-ACLR. Reported dynamic knee instability was the only factor associated with ongoing post-surgical knee impairments after ACLR. Rehabilitation programs should address athletes' psychological responses and resolve knee impairments to optimize return to pre-injury sport level after ACLR.

The study aimed to determine differences in sagittal-plane joint biomechanics between athletes with and without knee osteoarthritis (OA) during drop vertical jump 2 years after anterior cruciate ligament reconstruction (ACLR). Forty-one athletes with ACLR completed motion analysis testing during drop vertical jump from 30 cm. Sagittal-plane peak joint angles and moments and joint contributions to total support moment (TSM) were calculated during first landing. Medial compartment knee OA of the reconstructed knee was evaluated using Kellgren-Lawrence scores (ACLR group: Kellgren-Lawrence <2; ACLR-OA group: Kellgren-Lawrence ≥2). The ACLR-OA group (n = 13) had higher hip and lower knee contributions in the surgical limb than the ACLR group and their nonsurgical limb. Further, the ACLR-OA group had higher peak hip extension moment than the ACLR group (P = .024). The ACLR-OA group had significantly lower peak knee extension and ankle plantar flexion moments and TSM (P ≤ .032) than ACLR group. The ACLR-OA group landed with increased hip extension moment, decreased knee extension and ankle plantar flexion moments and TSM, and decreased knee and increased hip contributions to TSM compared with ACLR group. The ACLR-OA group may have adopted movement patterns to decrease knee load and compensated by shifting the load to the hip. Clinicians may incorporate tailored rehabilitation programs that mitigate the decreased knee load to minimize the risk of knee OA after ACLR.
RESUMO
CONTEXT: Hip muscle strength and hop performance limb symmetries after anterior cruciate ligament reconstruction (ACLR) are not well studied. This study aimed to determine the differences in hip abductors' (ABD) and external rotators' (ER) muscle strength measures between limbs, and the relationship between hip ABD and ER muscle strengths and hop performance limb symmetry indices (LSIs) 2 years after ACLR. DESIGN: Cross-sectional study. METHODS: Forty (level I/II) men athletes 2 years after unilateral ACLR completed 4 single-legged hop tests and involved hip ABD and ER strength testing (maximum voluntary isometric contraction [MVIC]; isokinetic peak torque [PKTQ] at 60°, 180°, and 300°/s; and isotonic peak velocity at 75% of their MVICs). Muscle strength measures were normalized to body mass, and hop performances were reported as LSIs. Paired t test was used to determine strength differences between limbs, and the Pearson correlation coefficient was used to assess the relationship between involved hip muscle strength measures and hop performance LSIs. RESULTS: Hip ER-MVIC (involved: 60.26 [12.01], uninvolved: 63.68 [13.17] N·m/kg) and ER eccentric PKTQ at 60°/s (involved: 32.59 [9.28]; uninvolved: 35.73 [10.50] N·m/kg) were significantly different between limbs (P ≤ .018). Single-hop LSI correlated with hip ER-PKTQ at 180°/s (r = .354) and 300°/s (r = .324, P ≤ .041), while triple-hop LSI correlated with hip ER-MVIC (r = .320), concentric ER-PKTQ at 180°/s (r = .355), eccentric ER-PKTQ at 60°/s (r = .314), and hip ABD-PKTQ at 60°/s (r = .364) and 300°/s (r = .336, P ≤ .049). CONCLUSIONS: Men athletes demonstrated symmetrical hop performance and hip muscle strengths, except for ER hip's MVIC and isokinetic eccentric peak torque at 60°/s 2 years after ACLR. Hop performance LSIs had a few, yet positive moderate relationships with involved hip ABDs and ER strength measures. This may indicate that hip ABD and ER muscle strength measures contribute to athletes' hop performances 2 years after ACLR. Post-ACLR rehabilitation programs might incorporate hip muscle strengthening training to improve athletes' functional performances.

INTRODUCTION: Closed femoral-shortening osteotomy over an intramedullary nail for the treatment of leg length discrepancy (LLD) is a demanding surgical technique, classically requiring specialized instrumentation (intramedullary saw and chisel). Herein, we describe our experience with shortening osteotomy over a nail, using a percutaneous multiple drill-hole osteotomy technique to perform the bone section with the osteotomized bone smashed and let on-site. METHOD: We operated on six patients with LLD due to: hemihypertrophy syndrome (three patients), congenital short femur, hemiplegic cerebral palsy, and growth plate injury. Mean femoral shortening was 4.2 cm. Osteotomy was performed via a multiple drill-hole technique, and femurs were stabilized using an intramedullary nail. Post-operative clinical and radiological data were recorded. Residual LLD was assessed through long-standing teleroentgenography. RESULTS: Shortening was achieved, with a final LLD of < 1 cm in all patients. All patients were satisfied and considered the lengths of the lower limbs to be equal. Our technique did not require special surgical skill or specialized instrumentation. Moreover, we did not record intraoperative and post-operative complications. DISCUSSION: Percutaneous femoral-shortening osteotomy over a nail using the on-site smashing osteotomy technique was effective and safe in treating LLD in this initial case series.

Epidermoid cysts are asymptomatic, slowly enlarging, firm to fluctuant, dome-shaped lesions. Epidermoid cysts frequently appear on the trunk, neck, face, and scrotum, behind the ears and in the palmoplantar region. We review all the cases of epidermoid cyst of the knee and present a case of non-traumatic-induced epidermal cyst in the popliteal fossa of a 66-year-old male with 10-year history of right knee swelling, which appeared firstly as a small mass 2 × 2 cm in the popliteal aspect of the knee. The mass was increasing gradually in size until 2 years ago when it increased suddenly to gain the dimensions of 4 × 6 cm. MRI of the right knee revealed a well-defined cystic lesion in the subcutaneous tissue measuring about 7 × 5 × 5 cm containing internal debris and septations. He underwent complete surgical excision of the mass. The pathological results revealed an epidermal inclusion cyst. To the best of our knowledge, this is the second description for epidermal inclusion cyst involving the popliteal fossa. We were able to retrieve three cases of epidermal cyst of the knee from the literature since its first description in 2004. Including our case, we had a total of four cases of epidermal cyst of the knee. Three males and one female constituted the patients' sample. The mean age for the patients is 55. The epidermal cyst occurred equally in both knees. The popliteal fossa was the location for two epidermal cysts. Similarly, the prepatellar region was the location for another two cysts.

BACKGROUND: Knee osteoarthritis (OA) is a common and disabling disease among the elderly population. The optimal conservative treatment for knee OA is not well established. OBJECTIVE: This study aimed to assess the effectiveness of pulsed electromagnetic field (PEMF) combined with progressive resistance exercise (PRE) in improving physical function and pain in patients with knee OA. METHODS: Thirty-four patients with knee OA (17 in each group) participated in a single-blind randomized control study. Patients were randomly assigned to receive 24 sessions of either combined PEMF and PRE (treatment group) or PRE only (control group). Patients were evaluated at pre-treatment, post-treatment (2 months), and at 3-month and 6-month follow-ups using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Numeric Pain Rating Scale (NPRS); walking speed and 5-times chair stand test. Mixed ANOVA was used for statistical analysis with Bonferroni adjustments. RESULTS: There was no significant group-by-time interaction for any outcome (P> 0.05). However, both groups scored significantly higher on the NPRS and KOOS at post-treatment, 3-, and 6-month follow-up compared to their baseline. Further, both groups completed the 5-times chair stand test and walking speed test with significantly less time at all post-treatment time points than the pre-treatment. None of the study outcomes (NPRS, KOOS, walking speed, and 5 times chair stand) were significantly different between groups at any of the time points. CONCLUSION: Both treatment options, PRE only versus PRE with PEMF, were equally effective in decreasing pain and improving physical function in patients with knee OA. This would suggest that the optimal parameters for PEMF that may show beneficial effects for knee OA when added to PRE training need to be determined.

BACKGROUND: Patients with anterior cruciate ligament reconstruction (ACLR) demonstrate lower knee loading. This study aimed to determine whether sagittal plane TSM and joint contributions to total support moment (TSM) in the surgical limb are different between athletes who did and did not show radiological features of knee OA at 2 years after ACLR during triple hops (TH), single hop (TH), single-legged vertical jump (VJ), and walking. METHODS: Forty-one athletes with 2 years of unilateral ACLR surgery participated in this cross-sectional study. Athletes completed motion analysis testing of single-legged TH, SH, VJ, and walking tasks. Sagittal plane TSM and individual joint (ankle, knee, and hip) contributions to TSM were computed at peak knee flexion angle (TSM-PKF). Posterior-anterior radiographs were completed in standing and 30° knee flexion. Kellgren-Lawrence (KL) system was used to identify radiological features of knee OA in the medial compartment of the reconstructed knee (OA-group: KL ≥2; Non-OA group: KL<2). RESULTS: There was a significant group-by-joint-by-task interaction for joint contributions to TSM-PKF (p = 0.012), with the OA-group (n = 13) had lower knee and higher hip contributions compared to the non-OA group during TH, SH, and VJ (p ≤ 0.049). There was a significant joint-by-group interaction for the joint contributions to TSM-PKF (p = 0.004), with the OA-group having lower knee (p = 0.003) and higher hip (p = 0.001) contributions compared to the Non-OA group. SIGNIFICANCE: The OA-group exhibited lower knee and higher hip contributions to the sagittal plane TSM compared to the Non-OA group during the landing phase of single-limb high-demand activities. The OA-group exhibited decreased knee loading and compensated by shifting the mechanical load to the hip joint within the reconstructed knee. Decreased knee loading in the OA-group may have affected the required mechanical loading to maintain knee metabolism and integrity.

BACKGROUND AND OBJECTIVES: Knee pain, specifically patellofemoral pain (PFP), may lead to limitations in physical activity and social participation. Identifying knee pain that is attributed to PFP is not an easy job for healthcare professionals. To overcome this issue, The Survey Instrument for Natural History, Aetiology and Prevalence of Patellofemoral Pain (SNAPPS), which is a self-reporting questionnaire instrument, was designed to identify PFP in many languages. However, the Arabic version of the SNAPPS is not validated yet. This study was performed to assess the validity and reliability of the Arabic version of the SNAPPS (A-SNAPPS). MATERIALS AND METHODS: A cross-sectional study was conducted to achieve the study goals. To assess reliability, 38 participants were asked to complete the A-SNAPPS two times on the same day with a 30 min break in between. Convergent validity of the A-SNAPPS was assessed by exploring the correlations of the SNAPPS total score with the visual analogue scale (VAS) scores, including VAS for usual pain, VAS for worst pain, and VAS for pain during activities such as jumping, running, ascending and descending stairs, and squatting. RESULTS: The validity test findings suggested that SNAPPS has a strong correlation with the VAS during ascending and descending stairs (r = 0.71) and moderate correlations during jumping (r = 0.54) and squatting (r = 0.57). The test-retest reliability ICC was 0.92, indicating a very strong test-retest reliability of the A-SNAPPS. CONCLUSIONS: The A-SNAPPS was cross-culturally adapted and validated, demonstrating very strong reliability.

BACKGROUND: Musculoskeletal (MSK) pain is a debilitating multi-perceptual condition afflicting many individuals, especially individuals in the medical profession. OBJECTIVE: To analyze and evaluate the prevalence of musculoskeletal pain among medical students at Jordanian universities during the complete virtual learning process. METHODS: A cross-sectional study of 593 medical students at two Jordanian universities was conducted. A modified Nordic questionnaire was used to assess musculoskeletal pain in three body regions. RESULTS: Five hundred ninety-three students at the two Jordanian universities participated in this study. The prevalence of having MSK pain during the past week in the neck, shoulder, and lower back was 34.6%, 27%, and 41%, respectively; during the past 12 months, it was 61.2%, 45.5%, and 63.1%, respectively. Overall prevalence of having MSK pain was 58.9% in the last week and 78.1% in the past 12 months. 66.8% of students who had psychosomatic symptoms and 62.3% of those with depressive symptoms in the past week had MSK pain. Students who studied 8 hours per day had higher percentages of MSK pain (68.4%) (OR 1.12, 95% CI 0.965-1.312). The average number of hours using a computer per day was significantly associated with MSK pain (p= 0.032). MSK pain during the last week was significantly associated with psychosomatic symptoms (OR 1.842, 95% CI 1.272-2.668, p= 0.001). Family history of MSK pain was significantly related to the presence of the problem in participants (OR 1.732, 95% CI 1.182-2.538, p= 0.005). Gender, depressive symptoms, average hours of computer use per day, and average hours of study at home per day did not show significant relationships with MSK pain over the year. CONCLUSIONS: High prevalence of MSK pain was observed among medical students. Measures to balance in-person and virtual learning should be considered in medical schools to minimize the risk of MSK pain.

The International Knee Documentation Committee Subjective Knee Form (IKDC2000) and the Knee Injury and Osteoarthritis Outcome Score (KOOS) are knee-specific measures. However, their association with a return to sports after anterior cruciate ligament reconstruction (ACLR) is unknown. This study aimed to investigate the association between the IKDC2000 and the KOOS subscales and the return to the same pre-injury level of sport two years after ACLR. Forty athletes that were two years post-ACLR participated in this study. Athletes provided demographic information, filled out the IKDC2000 and KOOS subscales, and indicated whether they returned to any sport and whether they returned to the same pre-injury level (same duration, intensity, and frequency). In this study, 29 (72.5%) athletes returned to play any sport and eight (20%) returned to the same pre-injury level. The IKDC2000 (r: 0.306, p = 0.041) and KOOS quality of life (KOOS-QOL) (r: 0.294, p = 0.046) significantly correlated with the return to any sport, but it was age (r: -0.364, p = 0.021), BMI (r: -0.342, p = 0.031), IKDC2000 (r: 0.447, p = 0.002), KOOS-pain (r: 0.317, p = 0.046), KOOS sport and recreation function (KOOS-sport/rec)(r: 0.371, p = 0.018), and KOOS QOL (r: 0.580, p > 0.001) that significantly correlated with a return to the same pre-injury level. High KOOS-QOL and IKDC2000 scores were associated with returning to any sport, and high KOOS-pain, KOOS-sport/rec, KOOS-QOL, and IKDC2000 scores were all associated with returning to the same pre-injury level of sport.
RESUMO
BACKGROUND: Patients demonstrate decreased knee loading and energy absorption after anterior cruciate ligament reconstruction (ACLR). This study aimed to determine the differences in the contribution of joints to the absorbed energy between athletes with and without radiological signs of knee OA 2 years after ACLR during drop jump (DJ) landing from 20, 30, and 40 cm. METHODS: Forty-one (level I/II) athletes 2 years after ACLR participated in this cross-sectional study and completed motion analysis testing of DJ. Proportional contribution of the joints (foot, ankle, knee, and hip) to the absorbed energy were computed. Posterior-anterior bent-knee radiographs were completed and graded in the medial compartment of the reconstructed knee using the Kellgren-Lawrence (KL) system (OA group: KL ≥2; Non-OA group: KL<2) RESULTS: Thirteen (31.7%) athletes showed radiological signs of knee OA in the medial compartment. There was a significant joint-by-group-by-limb interaction for the contribution of joints to absorbed energy during DJ 40 cm (p ≤ 0.019) and a joint-by-group interaction for the contribution of joints during DJ 20 cm (p = 0.018). The OA group had a lower involved knee (p = 0.043) and higher involved hip contributions (p = 0.014) compared to the Non-OA group, and the non-involved knee (p = 0.007). While the Non-OA group had a lower involved ankle contribution (p = 0.045) compared to their non-involved ankle during DJ 40 cm. The OA group also had higher involved hip contribution than the Non-OA group (p = 0.010), lower involved knee (p = 0.002), and higher involved hip contribution than the non-involved limb during DJ 20 cm. SIGNIFICANCE: The OA group may have adopted a compensatory pattern characterized by a decreased involved knee and increased involved hip to attenuate absorbed energy compared to the Non-OA group and their non-involved limb. The contribution of joints to the absorbed energy during DJ landing might be used as an assessment tool to identify patients with radiological signs of knee OA after ACLR.

Background: The factors contributing to soccer injuries and their influence on the occurrence of injury are controversial and inconclusive. This study aimed to determine the association between player characteristics and playing factors with injuries in professional soccer players. Methods: One hundred and fifty-two professional soccer players completed a self-administered questionnaire that asked about demographic information and injury profile, the type of playing surface on which they sustained their injury, medical treatment, and the time lost due to soccer injury at the end of the soccer season. Results: The injury rate was 44.74% (n = 68; males: 61.50% (n = 56), females: 19.70% (n = 12)). Players' age (OR: 1.15, 95%CI: 1.05−1.25, p < 0.002) and BMI (OR: 1.21, 95%CI: 1.06−1.38, p < 0.003) were significantly associated with soccer injuries. After adjusting for age and BMI, players' sex (OR: 5.39, 95%CI: 2.11−13.75, p < 0.001), previous soccer injury (OR: 3.308, 95%CI: 2.307−29.920, p < 0.001), and playing surfaces (OR: 11.07, 95%CI: 4.53−27.03, p < 0.001) were the significant predictors of soccer injuries. Conclusion: Players' age, BMI, sex, previous soccer injury, and playing surface were associated with injuries among professional soccer players. Old male athletes with high BMI, previous soccer injuries, and playing on natural grass were more likely to sustain soccer injuries than young female players with low BMI who had no previous injuries and played on synthetic surfaces.
RESUMO
BACKGROUND: There is inconsistency in the relationship between sleeping measures and the occurrence of soccer injuries. Further, most studies investigated sleeping quantity and quality during soccer season but not during off-season. The purpose of this study was to determine the influence of sleeping off-season and during soccer season on the occurrence of injuries in professional soccer players. It was hypothesized that lower sleeping hours and players' thought of inadequate sleeping quantity and quality during off-season and soccer season would associate with the occurrence of soccer injuries. METHODS: One-hundred and fifty-two professional soccer players (premier league and division I teams, age: 21.82±4.44, BMI: 22.21±2.74, sex: men [N.=91], women [N.=61]) answered questions related to their sleeping duration and whether that amount of sleep was enough prior to (off-season) and during soccer season. The sleep questions related to sleep quantity were derived from the Arabic Pittsburgh Sleep Quality Index. Players indicated also. Players indicated their injury profile, medical treatment, and time loss due to soccer injury. Sleeping measures were evaluated using univariate and multivariate logistic regression models to determine predictors of soccer injuries. RESULTS: Sixty-eight players (44.73%) were injured. Lower total sleeping time during off-season (OR:0.66, 95% CI:0.51-0.85, P=0.002), answering no on "did you regularly get enough sleep during off-season" (OR: 5.64, 95% CI: 2.58-12.27, P<0.001), and answering no on "do you think that your sleeping hours during off-season were enough" (OR:4.76, 95% CI: 1.98-11.46, P=0.001) associated significantly with soccer injuries (R2:38). CONCLUSIONS: Lower total sleeping time and not getting regularly enough sleeping time during off-season associated with more soccer injuries. This highlights the influence of sleeping quantity and quality off-season on the occurrence of soccer injuries among professional players.

BACKGROUND: Clinical outcomes after negative-pressure wound therapy (NPWT) and standard treatment of conflict-related extremity wounds are similar. In resource-limited settings, cost affects the choice of treatment. We aimed to estimate treatment-related costs of NPWT in comparison with standard treatment for conflict-related extremity wounds. METHODS: We derived outcome data from a randomized, controlled superiority trial that enrolled adult (≥ 18 years) patients with acute (≤ 72 h) conflict-related extremity wounds at two civilian hospitals in Jordan and Iraq. Primary endpoint was mean treatment-related healthcare costs (adjusted to 2019 US dollars). RESULTS: Patients were enrolled from June 9, 2015, to October 24, 2018. A total of 165 patients (155 men [93.9%]; 10 women [6.1%]; and median [IQR] age, 28 [21-34] years) were included in the analysis. The cost per patient treated with NPWT was $142 above that of standard treatment. Overall, results were robust in a sensitivity analysis. CONCLUSIONS: With similar clinical outcomes compared to standard care, our results do not support the use of NPWT in routine treatment of conflict-related extremity wounds at civilian hospitals in resource scarce settings. Trial registration NCT02444598.

OBJECTIVES: To determine predictors for return to previous level of sports after anterior cruciate ligament reconstruction (ACLR). DESIGN: Cross-sectional; SETTING: Athletic teams. PARTICIPANTS: Ninety-one athletes who had ACLR with hamstring-tendon autograft within 1-5 years participated in this study. Athletes indicated their sport participation levels, injury profile, rehabilitation duration, and time to start sport-related activities (running, cutting-pivoting) after ACLR. Athletes answered whether they returned to the same previous level of frequency, duration, and intensity of sports. MAIN OUTCOME MEASURES: Athletes' characteristics, injury and surgical factors, duration of post-operative rehabilitation program, and time to start sport-related activities after ACLR were evaluated by univariate logistic regression to determine predictors for return to previous level of sports. RESULTS: Nine athletes (10%) returned to their self-described previous level of sports. Predictors for returning to previous level of sports were rehabilitation duration >4 months (OR:6.78; p = .011), time to start running ≤4 months (OR:8.62; p = .047) and cutting-pivoting <6 months after surgery (OR:5.02; p = .030). CONCLUSION: Longer post-operative rehabilitation duration and time to start sport-related activities after ACLR predicted return to previous level of sports. Spending adequate time in post-operative rehabilitation program and time-based resumption of sports-related activities after ACLR might be key factors for returning to previous sports level.

OBJECTIVE: Primary tumors of bone are relatively uncommon. Little information is available about the etiology, pathophysiology, risk factors and epidemiologic features of bone tumors. In this article, we present the epidemiological data about the primary (benign and malignant) bone tumors in Jordan. METHODS: Retrospectively, we identified and assessed those patients who were diagnosed with primary bone tumor between January 2004 and December 2018 at King Abdullah University Hospital. The following information was obtained: demographics (age, sex), clinical presentation, and location of the tumor. Also, the histopathological results and finding and recurrence of the tumors were retrieved. The included primary bone tumors were those tumors fulfill the World Health Organization classification of soft tissue and bone tumors. RESULTS: During the study period, four-hundred and thirty-seven cases of the primary bone tumor were diagnosed in our institution. More than half of the cases were males (52.5% males and 47.5% females). In most cases, young adults are affected. The mean age for the diagnosis of giant cell tumor of bone (GCTB) is 34.1 years. The appendicular skeleton was involved in 269 (81.5%) patients while the axial skeleton in 60 patients. The most common encountered pathology is the multiple myeloma with 120 patients. After that, osteochondroma was diagnosed in 110 patients. Females were mostly affected by giant cell tumor while the osteochondroma and chondrosarcoma were seen mostly in males. Multiple myeloma tends to develop in elderly while juvenile ossifying fibroma occurred in young pediatrics and Ewing sarcoma in school-age children and adolescents. Giant cell tumor and osteoid osteoma have the tendency to recur. CONCLUSION: The diagnosis of primary bone tumors is of particular important. The reporting of epidemiological studies is essential in order to expand our knowledge regarding this uncommon type of tumors.

BACKGROUND: Morbid obesity is a challenge in cases that require total knee arthroplasty, and several studies considered it a contraindication for the procedure due to associated risk of complications, including plummeting hemoglobin levels and subsequent need for a blood transfusion. This study investigated risk factors for blood transfusion in this patient group and considered their relationship to obesity. MATERIALS AND METHODS: Patients' data were extracted from medical records, including estimated blood loss and perioperative hemoglobin levels. Patients were weighed and measured, and their body mass index (BMI) was calculated and stratified according to international criteria. RESULTS: A total of 188 patients were included in this study; among them, 136 patients had obesity (72%), with a mean BMI of 33.54. The mean volume of blood lost was 1055.4 ml, with the mean postoperative hemoglobin decrease of 1.42 g/dl and 2.88 g/dl at 6 and 24 h after surgery, respectively. The pre-operative Hb level was the only significant risk factor for blood transfusion. BMI did not affect the risk of blood transfusion or amount of blood lost. CONCLUSION: Obesity (BMI > 30 kg/m2) did not increase the risk of needing a blood transfusion after total knee arthroplasty. A judicious transfusion strategy involving the pre-operative Hb optimization should be adopted in TKA to decrease transfusion rate, benefit patient outcomes, and increase healthcare system efficiency. This study shows that high BMI is not a risk factor for postoperative blood transfusion.
RESUMO
OBJECTIVE: In this article, we aim to revisit the synthetic graft and review the advantages and disadvantages between different types of grafts for patients who underwent anterior cruciate ligament (ACL) reconstruction in a tertiary medical institute for the new generations of surgeons. PATIENTS AND METHODS: Retrospectively, we identified 115 patients who underwent arthroscopic ACL reconstruction between 2006 and 2009. We were able to retrieve 74 patients from them. The 74 patients were divided into 32 patients who underwent primary arthroscopic ACL reconstruction with hamstring and patellar tendon autograft and 42 cases with an active biosynthetic composite (ABC) ligament. The mean the follow-up period for both groups was 7 years. The following information was obtained: standard demographic information (age, sex), clinical presentation, presence of trauma, associated injuries, types of grafts (autograft versus synthetic graft) and postoperative complications. Moreover, functional and clinical outcomes in addition to the satisfaction of patients using the international knee documentation committee (IKDC) score and knee injury and osteoarthritis outcome score (KOOS) were measured. RESULTS: We found that the natural (autograft) was better in terms of clinical and functional outcome than the synthetic one (the scores of KOOS and IKDC were better in natural grafts). Furthermore, the immediate postoperative results for the pivot and Lachman tests were better in natural grafts. On the other hand, the rate of re-rupture was similar for both groups. However, the long-term inflammatory changes and stiffness that is attributed to the immunological reactions were more in the synthetic grafts. CONCLUSION: This study revisited the synthetic graft and provided evidence that the natural grafts are more beneficial with less complications, as they had better immediate and long-term postoperative clinical and functional outcomes. We recommend the utilization of autograft as first choice and the synthetic not to be used given the current criteria.
RESUMO
BACKGROUND: In armed conflict, injuries among civilians are usually complex and commonly affect the extremities. Negative pressure wound therapy (NPWT) is an alternative to standard treatment of acute conflict-related extremity wounds. We aimed to compare the safety and effectiveness of NPWT with that of standard treatment. METHODS: In this pragmatic, randomised, controlled superiority trial done at two civilian hospitals in Jordan and Iraq, we recruited patients aged 18 years or older, presenting with a conflict-related extremity wound within 72 h after injury. Participants were assigned (1:1) to receive either NPWT or standard treatment. We used a predefined, computer-generated randomisation list with three block sizes. Participants and their treating physicians were not masked to treatment allocation. The primary endpoint was wound closure by day 5. The coprimary endpoint was net clinical benefit, defined as a composite of wound closure by day 5 and freedom from any bleeding, wound infection, sepsis, or amputation of the index limb. Analysis was by intention to treat. The trial is registered with ClinicalTrials.gov, number NCT02444598, and is closed to accrual. FINDINGS: Between June 9, 2015, and Oct 24, 2018, 174 patients were randomly assigned to either the NPWT group (n=88) or the standard treatment group (n=86). Five patients in the NPWT group and four in the standard treatment group were excluded from the intention-to-treat analysis. By day 5, 41 (49%) of 83 participants in the NPWT group and 49 (60%) of 82 participants in the standard treatment group had closed wounds, with an absolute difference of 10 percentage points (95% CI -5 to 25, p=0·212; risk ratio [RR] 0·83, 95% CI 0·62 to 1·09). Net clinical benefit was seen in 33 (41%) of 81 participants in the NPWT group and 34 (44%) of 78 participants in the standard treatment group, with an absolute difference of 3 percentage points (95% CI -12 to 18, p=0·750; RR 0·93, 95% CI 0·65 to 1·35). There was one in-hospital death in the standard treatment group and none in the NPWT group. The proportion of participants with sepsis, bleeding leading to blood transfusion, and limb amputation did not differ between groups. INTERPRETATION: NPWT did not yield superior clinical outcomes compared with standard treatment for acute conflict-related extremity wounds. The results of this study not only question the use of NPWT, but also question the tendency for new and costly treatments to be introduced into resource-limited conflict settings without supporting evidence for their effectiveness. This study shows that high-quality, randomised trials in challenging settings are possible, and our findings support the call for further research that will generate context-specific evidence.
