Orthopedic surgeons commonly perform corticosteroid injections. These injections have systemic side effects, including suppression of the hypothalamic-pituitary adrenal axis. Due to this suppression, there is a theoretical risk of corticosteroid injections affecting the efficacy of the novel COVID-19 vaccines. This potential interaction led the American Academy of Orthopedic Surgeons to recommend, “avoiding musculoskeletal corticosteroid injections for two weeks before and one week after COVID vaccine administration.” This review examines the literature underlying this recommendation. An extensive literature review was performed through PubMed, MEDLINE, and Google Scholar from database inception to May 2022. Keywords searched were COVID, coronavirus, vaccine, vaccination, steroids, and corticosteroids. Search results included articles written in the English language and encompassed reviews, case series, empirical studies, and basic science articles. There is no definitive evidence that corticosteroid injections affect COVID-19 vaccine efficacy or increase the risk of contracting COVID. The authors recommend orthopedic surgeons follow the AAOS guidelines, which recommend avoiding injections two weeks before and one week following COVID vaccine administration. Additional research is needed to better define this theoretical risk, especially since there is good evidence that injections suppress the hypothalamic-pituitary-adrenal-axis. Level of evidence: IV

In Adolescent Idiopathic Scoliosis (AIS), correction surgery can correct the maximum movement and balance of the spine. Under certain conditions for two simultaneous curvatures, the procedure, in which correcting one of the curvatures can result in the automatic correction of another curvature, is called selective fusion, attracting spine surgeons’ interest because of more movement in the spine. However, the majority of surgeons have not used this technique due to the lack of sufficient information. The current study aimed to totally investigate selective thoracolumbar/lumbar fusion and to provide accurate information on outcomes and complications of surgery for spinal surgeons. This technique can also help spinal surgeons have a better selection of patients ’ surgical procedures. Level of evidence: IV

Obtaining a blood-free surgical field is critical during carpal tunnel decompression (CTD) to identify anatomic structures and avoid iatrogenic injury. A tourniquet is often used to minimize bleeding and improve visualization. However, it may be associated with discomfort and intolerance when sedation is not employed. WALANT ("Wide awake local anesthesia no tourniquet") technique surgeries have become very popular and enable the patient to be involved in the procedure; in addition, the adrenaline avoids the use of the tourniquet and the discomfort it produces. We hypothesized that there is no difference in postoperative pain after CTD between local anesthetic with a tourniquet (LA-T) and WALANT technique. The objective of this paper is to report the results of CTD, comparing those performed with local anesthesia and those performed with the WALANT. In this prospective study, 60 CTS were operated in two different institutions. Patients in group 1 (30 patients) were operated under LA-T, while patients in group 2 (30patients) were operated on using lidocaine with epinephrine (WALANT). Statistical analysis was performed. Postoperative pain immediately after surgery, at 4 and 24 hours, and 15, and 30 days after surgery; and degree of satisfaction did not show a significant difference between the two groups. Moreover, surgical time was slightly shorter in the LA-T group, but the difference was not significant. In our study, CTD performed with LA-T, and WALANT technique resulted in similar results. In cases of experienced surgeons, LA-T may be enough to perform the procedure, avoiding epinephrine's low but complex complications. In less experienced surgeons who require more surgical time, the use of WALANT may increase the intraoperative comfort of the patient.  Level of evidence: IV

Many surgeons avoid performing unicompartmental knee arthroplasty (UKA) due to various concerns. Cohort studies showing the satisfactory outcomes of UKA can convince surgeons to use this technique. In this study, we report the mid-term outcomes of UKA in a series of patients with medial compartment knee osteoarthritis. Seventeen patients with unicompartmental degenerative joint disease of the knee that underwent UKA and were available for final evaluation were included. The mean age of the patients was 63 ± 5.1 years. The mean follow-up of the patients was 37.2 ± 18.3 months. The outcome measures were the Oxford Knee Score (OKS), Knee Society Score (KSS) for knee score and knee function, Knee injury and Osteoarthritis Outcome Score (KOOS), knee range of motion (ROM), and satisfaction rate on a 5-point Likert scale. In the last follow-up visit, the mean of OKS and knee score section of the KSS were 44.6 ± 3.2 and 83.8 ± 2.1, respectively. The mean knee function section of the KSS was measured at 98.2 ± 7.2. The mean KOOS score and the mean knee ROM were 84 ± 9.4 and 134.4 ± 7º, respectively. The mean VAS for pain was 8.9 ± 1.1 (range 8-10) before the operation and 1.2 ± 0.8 (range 0-2) at the last follow-up. All the patients were very satisfied (n=14) or satisfied (n=3) with the results. No postoperative complication or reoperation was recorded during the follow-up. Unicompartmental knee arthroplasty provides satisfactory outcomes and a high survival rate, at least in mid-term follow-up. These findings suggest increased use of UKA in future workups. Level of evidence: IV

The aim of the study is to evaluate the impact of cirrhosis on inpatient hospital complications and healthcare costs in elective Total Hip Arthroplasty (THA). A 4-year retrospective analysis of the Nation Inpatient Sample (NIS) database, who underwent elective THA stratified by the presence or absence of cirrhosis was performed (2016-19). The records of specific postoperative complications, the cost of care (COC), and the length of stay (LOS) were evaluated by statistical analysis.  The NIS database identified 367,894 patients who underwent THA, of which 1,134 (0.3%) were cirrhotic. In the unmatched analysis, patients with cirrhosis showed significantly elevated rates (P< 0.05) of in-hospital complications compared to non-cirrhotic controls, including mortality (0.7% vs. 0.1%), acute renal failure (9.2% vs. 2.5%), blood loss anemia (30.4% vs. 19.5%), pneumonia (1.1% vs. 0.3%), periprosthetic fracture (3% vs. 1.2%), dislocations (2.5% vs. 1.4%), infection (4.2% vs. 1%), wound dehiscence (0.8% vs. 0.1%) and blood transfusion (11.3% vs. 3.5%). After propensity matching, significantly higher rates of blood loss anemia (30.4% vs. 26.7%; P=0.05), periprosthetic dislocations (2.4% vs. 1%; P=0.008), and infections (4.2% vs. 2.7%, P=0.05) were seen in the cirrhotic cohort, while the rate of pulmonary embolism was significantly lower (0% vs. 0.8%, P=0.002), as was myocardial infarction (0.08% vs. 0.7%, P=0.017). Concerning LOS in the hospital, patients with cirrhosis stayed significantly longer in both the unmatched (4.2 vs. 2.3 days; P <0.001) and matched (4.2 vs. 3.68; P=0.016) controls. The average COC was greater in the cirrhotic group, with a mean value of $90,264 vs. $66,806.31 (P<0.001) in the unmatched and $90,624 vs. $80,676.87 (P=0.001) in the matched cohort. Cirrhosis is associated with longer lengths of stay, higher hospital costs, and a greater risk of perioperative in-hospital complications such as blood loss anemia, dislocation, and infection after THA. This data could assist during preoperative patient counseling and improve the strategies for effectively utilizing the finite healthcare resources without compromising patient care and financial compensation from payers.  Level of evidence: IV

The aim of this retrospective study is to evaluate if Rush nail fixation still has a role in distal fibular fractures surgery compared with locking plate in terms of fixation quality, complications, functional results and patient satisfaction level. This study included 109 patients (average age 56.05), who had undergone operative treatment for bi- or trimalleolar fractures between 2009 and 2014. The patients were evaluated retrospectively, divided in group A (57 patients treated with Rush nail) and group B (52 patients treated with locking plate). The patients were evaluated at an average 4.9 years of follow-up (SD: 1.01) with Olerud-Molander Ankle Score (OMAS), American Orthopaedic Foot and Ankle Society - Ankle-Hindfoot Scale (AOFAS) and Visual Analogue Scale (VAS) for clinical outcomes. Xrays were conducted to assess ankle osteoarthritis using the classification system by Takakura and joint space symmetry using measurements in comparison with contralateral ankles. The groups were homogeneous regarding age and gender. Patients treated with Rush Nail fixation (Group A) showed statistically significant worse clinical results at functional scores (78.1 Group A versus 88.7 Group B at the OMAS (P<0.05); 83.1 Group A versus 90.1 Group B at the AOFAS (P<0.05); higher pain levels in the VAS (3.9 Group A versus 2.4 Group B) and lower satisfaction rates (52.6% Group A versus 73.1% Group B (P<0.05)) in comparison with patients treated with locking plate fixation (Group B). However, infections rate was significantly lower in Group A (1.8%) than in Group B (9.6%) (P<0.05). Radiographic evaluation showed more cases of posttraumatic osteoarthritis in Group A (35.1% Group A versus 15.4% Group B (P<0.05)) and worse results in regards to restoration of joint space symmetry (45.6% Group A versus 73.1% Group B (P<0.05)). Results of current study indicates that even though plating of lateral malleolus in bimalleolar and trimalleolar fractures is superior in fracture reduction quality, early functional recovery, reduced incidence of posttraumatic osteoarthritis and greater patient satisfaction, Rush nail fixation still provides acceptable clinical results with a lower infection rate. Therefore Rush nails could be considered as a valid choice in selected patients with high risk of soft tissue complications or low functional demand. Level of evidence: III

Although the diffuse type of tenosynovial giant cell tumor (D-TGCT) is rare, bone involvement is common in such lesions. However, the optimal management of bone lesions in D -TGCT is not well-described. In this study, we reported the outcomes of total synovectomy, curettage, and bone grafting/cementation in the treatment of D-TGCT with subchondral bone involvement. We also described the prevalence, demographic, and characteristic features of the lesions. In a retrospective study, we included 13 patients with D-TGCT of large joints and associated subchondral cyst/cyst-like bone lesions of ≥ 5 mm that were managed with total synovectomy and curettage. Cavities with a bone defect of ≤ 30 mm (n=12) were filled with bone grafts. Cavities of > 30 mm (n=1) were augmented with bone cement. The limb function was evaluated by the Musculoskeletal Tumor Society (MSTS) score. The study population consisted of 6 (46.1%) males and 7 (53.9%) females with a mean age of 30 ± 7.9 years. The most frequent sites of involvement were the knees and ankle joints (n=5 each, 38.5%). The mean followup of the patients was 69.2 ± 32.9 months. The mean MSTS score of the patients was obtained at 98.2 ± 3.2 (range 90-100). The D-TGCT recurred in two patients, both of which were in the synovium. Postoperative complications were three cases of transient pain and one case of knee joint stiffness. While no patient had an osteoarthritic change in preoperative radiographs, two patients had osteoarthritic change (grade II) in the last follow-up, one in the knee and one in the hip. Curettage and filling the defect with bone graft or cement are adequate treatments for managing bone lesions in D-TGCT. Level of evidence: IV

The reconstruction of large bony defect caused by tumor resection can be managed by different technique like bone graft, Masquelet technique, mega-prosthesis etc. Literature lacks studies discussing Masquelet technique in tumor cases especially pertaining to infected tumor in adults. We aimed to determine 1) How often and how fast is the bone healing achieved after resection greater than 10 cm bone in tumour patient’s using Masquelet technique?, 2) Whether Masquelet technique can achieve optimum outcomes in adult infected cases too? We reviewed 154 patients of benign & malignant tumour managed by us between 2013 and 2019. Patients belonging to all the age group with infected tumor/diaphysial tumor/periarticular tumor, where single stage surgery or mega-prosthesis is not a viable option and were treated with Masquelet technique for reconstructing a bone defect of at least 10 cm were included in our study. We evaluated outcomes of eight patients for four parameters i.e. bony union, healing index, number of re-do surgeries required and limb length discrepancy. Mean age of our study group was 20.25 years and patients followed for mean duration of 3.36 years. Mean bone loss after tumor resection was 13.1 cm (range = 11.5 cm to 15 cm). There was no sign of recurrence of tumor in any patient at the time of last follow up. Average time required to achieve bony union was 23.25 months (mean healing index of 1.67 months/cm). All but one patient achieved bony union. Mean limb length discrepancy seen was 1.44cm. Infected cases showed low healing index with higher percentage of re-do surgeries. Induced membrane technique is quick, safe and reliable alternative method of reconstruction to megaprosthesis in cases with all age group where risk of failure of mega-prosthesis is high, either due to infection or shorter expected lifespan of prosthesis. However, obtaining union can be a difficult preposition in infected tumor cases and multiple surgeries may be required to get the desired result even after two stages. However, a comparative study with large sample size is required to further validate our results. Level of evidence: IV

A prospective cohort study to evaluate and compare the responsiveness of the Persian version of the neck disability index (NDI), neck pain & disability scale (NPDS), neck outcome score (NOOS), and to determine the minimal clinically important difference (MCID) and minimal detectable change (MDC). To date, no studies have made a direct comparison between the responsiveness of the Persian version of NPDS, NDI, and NOOS questionnaires. At the end of the study, 55 patients with chronic non-specific neck pain completed the NPDS, NDI, and NOOS questionnaires at the beginning and end of three weeks of physiotherapy treatment. Additionally, patients completed the global rating of change scale to differentiate between improved and unimproved patients. Comparison of responsiveness was performed using anchor-based methods (receiver operating characteristic (ROC) curve and correlation analysis). MCID and MDC were assessed to investigate relevant changes for each questionnaire. ROC curves analysis showed areas under the curves of 0.70, 0.64, and 0.43 to 0.63 for the NPDS, NDI, and NOOS subscales, respectively. The correlation coefficients between the global rating of the change scale and the change scores of the NPDS and NDI were 0.38 (P<0.01) and 0.30 (P<0.05), respectively. There were no significant correlations between NOOS subscales and global rating of change score (r=0.001- 0.21, P>0.05). The MCID for the NPDS, NDI, and NOOS subscales were 28.09 (score 0-100), 7.5 (score 0-50), and 13.75 to 28.64 (score 0-100), respectively. The MDCs were found to be in the following order: 47.1 points for NPDS, 36.1 for NDI, and 23.5 to 39.7 for NOOS subscales. The Persian NPDS seems more responsive than the NDI and NOOS questionnaires. The level of clinically meaningful change in NDI, NPDS, and NOOS questionnaires is in the range of measurement error.  Level of evidence: IV

Ponseti method of CTEV treatment includes use of a foot orthosis, compliance with this can be a challenge. A new brace- Abduction Dorsiflexion Mechanism brace (ADM, C-Prodirect) was introduced to address this. The aim of the study was to assess whether the new AD M brace improves compliance and prevents relapse in children with corrected clubfoot. Eight children with unilateral CTEV who did not tolerate the standard brace were included in the study. All children had been previously treated with Ponseti casting, Achilles tenotomy and Ponseti AFO Abduction Brace (C-Prodirect®). The mean age of children included was 27 months. Parents’ satisfaction with the brace was assessed using Client Satisfaction with Device (CSD) questionnaire. Parents reported better tolerance o f the brace by the child in six out of eight cases. ADM brace is viable alternative in maintaining correction of unilateral idiopathic CTEV when compliance to standard AFO abduction brace is poorly tolerated. Level of evidence: IV

Bilateral divergent fracture dislocations of the shoulder are very rare. Caution with regards to seizure development in COVID-19 patients must be taken to avoid such injuries. This is the case of a male COVID-19 patient who sustained hyponatremia-induced seizure that resulted in bilateral divergent shoulder fracture dislocations. The patient suffered a lesser tuberosity fracture on his left shoulder which was posteriorly dislocated, and a greater tuberosity fracture on his right, which was anteriorly dislocated. The patient underwent bilateral open reduction and internal fixation, with suture anchor fixation for the lesser tuberosity fracture on the left side, and a proximal humerus locking plate for the greater tuberosity fracture on the right side. Education on postoperative complications and expectations were provided to the patient. Level of evidence: IV

The aim of the present study is to investigate a possible relation between Moon cycle and Trauma deaths registered in Tehran cemetery organization (Behesht Zahra), for a 10 years period (March 1992 to March 2002). From 28,208 traumatic deaths were registered in Tehran cemetery, 22828 (80.9%) meet our conclusion criteria. There were 17,056 (74.7%) males and 5,772 (25.3%) females. There was not an increase in trauma deaths in the full moon and new moon days. A similar pattern was observed for the sex of death cases and intentional deaths. The mean age of deceased cases showed a significant increase in full moon days. Different factors could affect the frequency of trauma deaths. Hence, if there is any role for Full Moon on the occurrence of trauma and its deaths, it is not so strong that can be identified.Keywords: Trauma, Death, Full Moon, New Moon, Tehran.Level of evidence: VI
