Background: Plates and screws are frequently used for the fixation of displaced intra-articular calcaneus fracture (DIACF). In this study, we compared the outcomes of a modified screw fixation technique with plate fixation via a sinus tarsi approach (STA)., Methods: A series of 187 DIACF patients who were treated via an STA using a plate fixation (n = 81) or a screw fixation (n = 106) were included. Screw fixation was done with two 2.7 mm screws and two 6.5 mm cannulated screws. Outcomes were evaluated radiographically and clinically. Clinical evaluations included pain assessment by Visual Analogue Scale (VAS) and functional assessment by the American Orthopaedic Foot and Ankle Society (AOFAS) questionnaire and Foot Function Index (FFI)., Results: The mean final VAS was smaller in the screw group (P = 0.01). The mean AOFAS and FFI scores were not significantly different between the two groups (P = 0.17 and P = 0. 19, respectively). The mean improvement of Bohler's angle, but not the Gissane's angle, was significantly greater in the screw group (P = 0.014 and P = 0.09, respectively). The mean improvement of calcaneal length and height were not significantly different between the two groups (P = 0.78 and P = 0.22, respectively). The hardware removal rate was 14.8% in the plate group and 3.8% in the screw group (P = 0.007)., Conclusion: The modified screw fixation method provides lower pain, better radiographic outcome, and lower rate of hardware removal compared to plate fixation in the treatment of DIACF., (© 2024.

Background: Various fixation devices are available for bunion osteotomy. In this study, we evaluated the radiographic outcomes, postoperative complications, and recurrence rate in a series of hallux valgus deformities treated with various osteotomy procedures using a pin for the fixation of the osteotomy., Methods: Two-hundred forty-seven patients with hallux valgus deformity managed with a Simple, Effective, Rapid and Inexpensive (SERI) osteotomy, distal chevron osteotomy, or proximal crescentic osteotomy and K-wire fixation were included. The mean follow-up of the patients was 53.9 ± 8.9 months. Radiographic evaluations included the assessment of the Hallux valgus angle (HVA), intermetatarsal angle (IMA), and union. Clinical evaluations included the assessment of the range of motion, pain in the first metatarsophalangeal joint, and patient satisfaction., Results: In the last visit, the mean improvement of HVA was 23.9 ± 9.1º (P < 0.001). The mean IMA improvement was 6.1 ± 6º (P < 0.001). The mean metatarsophalangeal flexion and extension were 33 ± 10.7º and 34.6 ± 9.2º, respectively. Postoperative complications included pin tract infection in eight (3.2%) patients, deep infection in five (2%) patients, and early pin complication in four (1.6%) patients. Recurrence was observed in five (2%) patients. Twenty-three (9.3%) patients had slight pain in the last follow-up. The mean surgical time was smaller in the SERI osteotomy (P < 0.001). The mean hospitalization period was longer in the proximal osteotomy group (P = 0.039). The mean metatarsophalangeal flexion and extension were significantly smaller in the distal chevron osteotomy (P = 0.046 and P = 0.037, respectively). 90% of patients were satisfied or very satisfied with the surgical outcomes., Conclusion: K-wire fixation is a safe and effective device for the fixation of bunion osteotomy, and this effectiveness is even higher with SERI and proximal crescentic osteotomy., (© 2024.

Background: It is becoming increasingly important to study pathology at the knee and spine because of their role in causing pain and deformity in one another. Compression of the lumbar nerve root can disrupt innervation to the thigh muscles, cause an imbalance of muscle and result in varus deformity. In this study, we try to figure out the relation between lumbar spine disorders and genu varum and realize if lumbar spine disorders can cause varus deformity in a patient., Methods: In this cross-sectional study, the number of 53 patients with knee varus greater than 20 degrees who visited the orthopedic clinics of Rasoul Akram and Moheb Mehr hospitals affiliated to Iran University of Medical Sciences between 2020 and 2022 were investigated in terms of association with lumbar disorders. The demographic characteristics and clinical findings of the patients were recorded and collected using a checklist by referring to the patient's medical profiles. Radiographic findings were evaluated by referring to the imaging department and using the Pacs system. The diagnosis of the patients was based on the history and findings of the knee graph, which was measured with a goniometer to measure the knee angle. The frequency of lumbar disorders caused by pressure on the lumbar nerves in patients with genu varum deformity including canal stenosis, osteoarthritis, spondylolisthesis, and disc herniation was investigated. To investigate lumbar problems, patients' history and radiographic images as well as lumbosacral and knee MRI of patients were used., Results: The mean age was 66.3 ± 7.66 years. 40 (75.5%) cases were female and 13 (24.5%) cases were male. Lumbar canal stenosis with 28(52.8%) and disc herniation with 32(60.4%) were the most common lumbar disorders in patients with knee varus more than 20 degrees. The mean age of patients with varus of more than 20 degrees with lumbar disorders was significantly higher than that of patients without lumbar disorders. ( P : 0.001) There was no significant difference between gender distribution and lumbar disorders in patients with varus more than 20 degrees. Significant positive correlation between genu varum with lumbar canal stenosis (r: 0.53, P : 0.001), osteoarthritis (r: 0.38, P : 0.004), spondylolisthesis (r: 0.39, P : 0.002) and disc herniation (r: 0.46, P : 0.001) was reported2., Conclusion: An association between lumbar disorders and varus more than 20 degrees was found to be considerable., Competing Interests: The authors declare that they have no competing interests., (© 2024 Iran University of Medical Sciences.)

Background: In extra-articular distal femoral fractures (EDFFs), nonunion is a serious complication that occurs rarely. In this study, we examined how longer preservation of initial fracture hematoma by delaying the osteosynthesis (OS) affects the fracture union., Methods: In a retrospective cohort study, 98 EDFF patients were included. The OS was done within 2 days of injury in 50 patients (early OS group) and after 2 days of injury in 48 patients (late OS group). Time to callus formation and fracture union, bleeding amount, surgical duration, pain, knee range of motion, knee function, and postoperative complications, including the nonunion, knee deformity, infection, and revision, were compared between the 2 groups. Statistical analyses were done with SPSS. A comparison of the mean between the 2 groups was made with an independent t test or its nonparametric counterpart. A comparison of categorical variables between the 2 groups was made using a chi-square or the Fisher's exact test. P ˂ 0.05 was considered statistically significant., Results: The mean time to callus formation was 47.1 ± 17.3 days in the early OS group and 46.9 ± 19.7 in the late OS group ( P = 0.950). The mean time to fracture union was 114.9 ± 21 in the early OS group and 117.4 ± 28.8 days in the late OS group ( P = 0.630). The mean operation time and bleeding amount between the 2 groups did not differ significantly ( P = 0.230 and P = 0.340, respectively). The knee range of motion, pain, and function were not notably different ( P = 0.620, P = 0.790, and P = 0.770, respectively). Nonunion occurred in 3 patients of early OS and 2 patients of the late OS group. Other complications were also comparable in the 2 study groups., Conclusion: Delayed OA in EDFF patients has no significant effect on bone healing and fracture union. Future standard studies are required to confirm these results., Competing Interests: The authors declare that they have no competing interests., (© 2024 Iran University of Medical Sciences.)

Background: There is no clear consensus regarding the superiority of a combined anterior cruciate ligament reconstruction (ACLR) with anterolateral ligament reconstruction (ALLR) versus an isolated ACLR. In this study, we compared the postoperative stability profile, complications, and patient-reported outcomes of these procedures., Methods: Twenty-one patients with an anterior cruciate ligament (ACL) tear who were either treated by an isolated all-inside ACLR (n = 21) or a combined all-inside ACLR and ALLR (n = 20) were included. The outcomes were evaluated in the last follow-up and included the postoperative stability profile evaluated by the Lachman test, pivot shift test, and KT-1000 side-to-side difference, postoperative complications, and patient-reported outcomes evaluated by the International Knee Documentation Committee (IKDC) score and Lysholm knee scale., Results: The baseline characteristics of the two groups were not significantly different. The residual Lachman and pivot shift were not significantly different between the two groups (P = 0.41 and P = 0.18, respectively). The mean KT-1000 side-to-side difference was 1.93 ± 1.9 mm in the isolated and 1.635 ± 0.91 mm in the combined group (P = 0.01). The mean improvement of the IKDC score was not significantly different between the isolated and combined groups (24.7 vs. 25.2, P = 0.28). The mean improvement of the Lysholm scale was not significantly different between the isolated and combined groups (33.5 vs. 34.1, P = 0.19). ACL re-rupture occurred in three patients of the isolated group and no patient of the combined group., Conclusion: The outcomes of patients in the present study support performing a combined ALL and ACL reconstruction., (© 2023.

Objectives: Supracondylar humerus fracture (SHF) is the most common fracture observed in children. The present study aimed to assess the characteristic parameters in one of the most extensive available pediatric SHF series referred to a tertiary hospital in Iran., Methods: The medical profiles of the SHF patients who were referred to our tertiary hospital between January 2017 and January 2022 were retrospectively reviewed. The inclusion criteria entailed age < 14 years and a radiographically confirmed diagnosis of SHF. The collected data included age, gender, side of injury, mechanism of injury, season of the injury, concurrent complications, type of fracture, and treatment., Results: A total of 1,309 patients with a mean age of 7.7±2.7 years were included in this study. The incidence of SHF was 1.8-fold higher in males, while the mean age of incidence was significantly lower in female patients (7.2 vs. 8 years; P<0.001). Falling was the most frequent mechanism of injury (97%). Gartland type I was the most prevalent type of injury (n=482; 36.8%). Moreover, the majority of fractures were extension-type (n=1,249; 95.4%). Most patients were managed conservatively (n=785; 60%). Concurrent fractures as well as neuralgic, vascular, and muscular complications were present in 3%, 1.45%, 1.22%, and 0.5% of patients, respectively., Conclusion: As evidenced by the results of this study, SHF is prevalent among the Iranian pediatric population. Therefore, greater awareness is required regarding the high incidence of this fracture in this population and its adequate management with respect to concurrent complications, particularly neurovascular compromise., Competing Interests: None, (2024 © BY THE ARCHIVES OF BONE AND JOINT SURGERY.)

Background: Deferoxamine (DFO) angiogenesis induction potential has been demonstrated in earlier studies, but not in the osteonecrosis of the femoral head (ONFH). In this study, we evaluated the outcome of ONFH treated with combined core decompression and local DFO administration loaded on Polylactic Glycolic Acid (PLGA)., Patients and Methods: In a pilot experimental study, six patients (10 hips) with early-stage non-traumatic ONFH were treated by core decompression, and concurrent injection of local DFO loaded on PLGA scaffold into the subchondral femoral head. Outcome measures were evaluated before the surgery and 12 and 24 months after the surgery and included visual analog scale (VAS) for pain, modified Merle d'Aubigné-Postel (MAP) score for hip function by MRI, and rate of osteonecrosis assessed by the modified., Results: The mean MPA score was 14.7 ± 1.16 before the surgery and 16.7 ± 1.41 one year after the surgery (P = 0.004). The mean VAS for pain was 4.7 ± 1.25 before the surgery and 1.8 ± 1.03 one year after the surgery (P = 0.005). The mean Kerboul angle was 219 ± 58.64 before the operation and 164.6 ± 41.82 one year after the operation (P < 0.001). Osteonecrosis progression or collapse was not seen in any of the patients at the final follow-up. No postoperative side effect attributed to the DFO was noticed, as well., Conclusion: In short-term follow-up, combined core decompression and local DFO administration not only prevent the progression of ONFH but also reduces the rate of osteonecrosis significantly. However, future controlled studies are required to confirm the present results., Trial Registration: IRCT20161121031003N3, 16/04/2019., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Coronavirus disease 2019 (COVID-19) patients who undergo hip fracture surgery are expected to have worse outcomes because they are vulnerable to developing COVID-19-associated complications. The present review attempted to assess the in-hospital and 30-day mortality rates as well as the length of hospital stay in patients with COVID-19 infection who had hip fracture surgery., Methods: Two authors independently searched Google Scholar, PubMed, Web of Knowledge, SCOPUS, and Embase, based on the MeSH-matched scientific keywords. The nine-star Newcastle-Ottawa Scale (NOS) scoring system was employed to assess the methodological quality of all eligible studies., Results: Eleven cohort studies that included 336 patients comprised the study. Three studies reported in-hospital mortality. Eight studies reported 30-day postoperative mortality. The pooled in-hospital mortality rate was 29.8% (95% CI: 26.6%-35.6%). The pooled 30-day postoperative mortality rate was 35.0% (95% CI: 29.9%-40.5%). The mean hospital stay was 11.29 days (95% CI: 10.65 days-11.94 days)., Conclusions: The rates of in-hospital and 30-day mortality in COVID-19 patients who undergo hip fracture surgery is high. These data suggest delaying hip fracture surgery until COVID-19 infection of the patients is controlled., Level of Evidence: Level II., (Copyright © 2022 Wolters Kluwer Health, Inc.
