Which factor is more reliable considering prophylactic pinning of contralateral hip of unilateral SCFE patients?

BACKGROUND: This study evaluates the radiological parameters of developing subsequent contralateral slips in unilateral slipped capital femoral epiphysis (SCFE) patients at the time of initial presentation. METHODS: The study group included the review of unilateral SCFE patients treated between June 2007 and August 2018. Age, gen-der, side, stability, posterior slope angle, grade of slip, modified Oxford bone age score (mOBAS), the Risser classification, and the ap-pearance of the triradiate cartilage were evaluated retrospectively. Data were analyzed between two groups: subsequent contralateral SCFE (SCFESC) patients that developed contralateral slip during follow-up and unilateral SCFE (SCFEU) patients that did not develop contralateral slip up to skeletal maturity. Descriptive statistics were used to compare risk factors between groups. RESULTS: This study included 48 patients and 6 patients (12.5%) developed a SCFESC. Only mOBAS was significantly different be-tween groups. The mOBAS scores in SCFESC were 18 in 2 patients (33.3%), 19 in 4 patients (66.7%). The mOBAS scores in SCFEU were 18 in 1 patient (2.4%), 19 in 24 patients (57.1%), and >20 in 17 patients (40.5%). In the SCFESC group, all patients had a Risser score of 0 and all had open triradiate cartilage. CONCLUSION: Patients with unilateral SCFE are at risk for SCFESC, and the mOBAS is the best predictor of risk assessment. We agree that mOBAS score of 16,17 or 18 patients' contralateral hips can be prophylactically pinned. We also suggest pinning or close screening of mOBAS 19 patients that some carry relatively high risk of subsequent contralateral slip.

Risk factors related reduction loss in nonoperatively treated Type II supracondylar humerus fractures.

BACKGROUND: Controversies continue about the optimal treatment method for extension Type II supracondylar humerus fractures (SCHFs). Although most patients are successfully treated with closed reduction and plaster casting, in some patients, the reduction initially obtained is lost during the time in the plaster cast. The aim of this study was to determine the risk factors causing reduction loss. METHODS: A retrospective examination was made of the data of 103 patients with Type II extension SCHF treated with closed reduction and plaster cast fixation between 2012 and 2018. Reduction loss was evaluated in respect of patient variables, fracture characteristics as obliquity and metaphyseal fragmentation, fixation method, and plaster cast parameters. RESULTS: The 103 patients evaluated comprised 62 males and 41 females with a mean age of 5.4±2.5 years (2-11.6 years). Successful treatment was achieved with closed reduction and plaster cast fixation in 81 (79%) patients and reduction loss was observed in 22 (21%) patients. The reduction loss of fractures showing high oblique in the sagittal plane was 3.17-fold higher than low sagittal oblique fractures (95% CI: 0.99-10.03, p<0.05). The risk of reduction loss in fractures with metaphyseal fragmentation was found to be 6.5-fold higher (95% CI: 1.6-26.5, p<0.01). No statistically significant relationship was determined between reduction loss and Gartland subtype, age, gender, the presence of rotation initially, plaster cast angle, and the soft-tissue/inner cast width ratio. CONCLUSION: According to our study group, 79% of extension Type II fractures can be successfully treated with closed reduction and plaster casting. Sagittal plane obliquity and metaphyseal fragmentation are risk factors for reduction loss independent of Gartland subtype.

Impact of the COVID-19 pandemic on orthopedic fracture characteristics in three hospitals in Turkey: A multi-center epidemiological study.

OBJECTIVES: The aim of this study was to evaluate the impact of novel coronavirus-2019 (COVID-19) on the epidemiological characteristics of orthopedic fractures. PATIENTS AND METHODS: A total of 2,960 patients (1,755 males, 1,205 females; mean age: 39.6 years; range, 1 to 98 years) with orthopedic fractures were included in the study: 552 patients during the pandemic period (March 10th and July 1st, 2020) and 1,158 control patients in the same period 2019 and 1,250 control patients in 2018. Epidemiological characteristics, injury mechanisms, fracture locations and treatment details of the patients were analyzed and compared between 2018, 2019 and 2020 for adult and pediatric populations. RESULTS: Of a total of 552 patients, 485 were adults and 67 were pediatric patients. In the control groups, of 1,158 patients (2019), 770 were adults and 378 were pediatric patients and, of 1,250 patients (2018), 857 were adults and 393 were pediatric patients. The proportion of proximal femur and hand fractures significantly increased during the pandemic period (p=0.025 and p=0.038, respectively). The most frequent surgical indication in the pandemic period was proximal femoral fracture. The proportion of home accidents as an injury mechanism significantly increased in the pandemic period compared to 2018 and 2019 (48.5% vs. 18.6% and 20.6%, respectively; p=0.000). The proportion of female pediatric patients significantly increased during the pandemic period compared to 2018 and 2019 (44.8% vs. 25.4% and 27.2%, respectively, p=0.004). The proportion of forearm fractures (p=0.001) also increased, and the proportion of tibia-fibula fractures (p=0.03) decreased. The most frequent surgical indication in pediatric patients was distal humeral fracture in both groups. CONCLUSION: During the pandemic period, proximal femoral fractures in the elderly remained a concern. In-home preventative strategies may be beneficial to reduce the incidence of hip fractures in the elderly.

Leaving the stable ramp lesion unrepaired does not negatively affect clinical and functional outcomes as well as return to sports rates after ACL reconstruction.

PURPOSE: To evaluate the effects of untreated stable ramp lesions on clinical and functional outcomes, return to sports rates, and complications of patients who underwent anterior cruciate ligament reconstruction. METHODS: A total of 879 patients with anterior cruciate ligament rupture were evaluated. Of these, 66 patients [33 patients with anterior cruciate ligament rupture and stable medial meniscal ramp lesion (ramp + group) and 33 patients with isolated anterior cruciate ligament rupture (ramp - group)] with a minimum 3-year of follow-up were included. Stable ramp lesions were not repaired in the ramp + group. Preoperative and postoperative Lachman and pivot-shift grades, Lysholm knee scores, International Knee Documentation Committee score and 12-Item Short Form Health Survey score were compared between groups. The return to sports rates, level of return to sports, time to return to sports and complications were compared. RESULTS: The mean patient age was 27.8 ± 7.2 years. The mean follow-up period was 47.3 ± 9.4 months. There were no significant differences between groups regarding preoperative and postoperative Lachman and pivot-shift grades, 12-Item Short Form Health Survey mental and physical component summary scores, Lysholm and International Knee Documentation Committee scores, and complication rates (n.s.). Although the return to sports rates (84.8% vs 90.1%) and the level of the return to sports (return to preinjury level: 75% vs 78%) were similar between groups (n.s.), the time to return to sports was significantly longer for patients with ramp lesions (11.1 ± 4.0 vs. 8.7 ± 2.5 months, p = 0.007). CONCLUSION: Leaving the stable ramp lesion unrepaired does not negatively affect clinical and functional outcomes as well as return to sports rates after ACL reconstruction. However, the time to return to sports is prolonged in patients with ramp lesions In clinical practice, surgeons should be aware that repairing stable ramp lesions is not an absolute necessity and will not affect return to sport rates. LEVEL OF EVIDENCE: Level III.

Increased femoral anteversion related to infratrochanteric femoral torsion is associated with ACL rupture.

PURPOSE: To determine the association between femoral torsion and anterior cruciate ligament (ACL) rupture and determine the level of torsion using magnetic resonance imaging (MRI). METHODS: The medical records of patients who were diagnosed with ACL injury were reviewed retrospectively. This descriptive epidemiological study included 2344 patients. MRI scans were examined and patients with femur and knee MRI scans obtained at the same time were identified (ACL-deficient group). Twenty-eight of them had femur and knee MRI scans because of an incidental benign lesion in the distal femur. Patients who were diagnosed with enchondroma were followed up by MRI evaluation of the femur and were randomly selected as controls. Supratrochanteric torsion (STT), infratrochanteric torsion (ITT), and femoral anteversion (FA) were measured by orthopedic surgeons with at least 5 years of experience. RESULTS: Age, sex, and side properties were similar in both groups. The mean FA values were 19.4 ± 3.0 degrees and 11.9 ± 2.0 degrees in the ACL-deficient and control groups, respectively (p < 0.001). STT was similar in the ACL-deficient and control groups [mean: 38.2 ± 4.3 and 37.7 ± 3.3, respectively, (n.s.)]. ITT was increased in the ACL-deficient group compared with the control group (mean - 18.8 ± 4.3 and - 25.8 ± 3.8, respectively; p < 0.001). CONCLUSIONS: According to our results, increased FA was associated with ACL rupture. Further, the torsional abnormality was developed from the ITT. We concluded that each ACL-deficient patient should be assessed by a clinician for torsional abnormality using physical examination. LEVEL OF EVIDENCE: III.
