Abstract Purpose: Traumatic lumbosacral fracture-dislocation is a very rare pattern of injury. We report a patient who has been suffered from a traffic accident and resulted in concomitant severe injuries: complex lumbosacral fracture-dislocation with pelvic ring disruption and vertical shear sacral fracture; Pneumothorax. Methods: She was transferred to the emergency department at the local provincial hospital and treated with the pelvic external fixation and closed drainage of thoracic cavity. For the further therapy, she was transferred to our hospital. The neurological examination revealed incomplete S1 paraplegia in the right lower extremity, the left lower extremity was normal, and rectal tone was existed. Standard x-rays and computed tomography revealed L5-S1 fracture-dislocation and fractures of the L5 transverse processes. Results: She was treated with S1 laminectomy and L5-S1 interbody fusion using lumbo-iliac internal fixation. Conclusions: Available literatures on lumbosacral fracture-dislocation were also reviewed which illustrate the pathogenic, clinical, radiological and therapeutic aspects of lumbosacral fracture dislocation.

Background: Metformin is the most commonly used drug for type 2 diabetes. Research has shown that metformin also has a protective effect on endothelium by decreasing endothelial vascular reactivity. We hypothesize that metformin will decrease restenosis/reintervention rates in patients receiving lower extremity non–drug-eluting stents (nDESs) in the superficial femoral artery(SFA) and/or popliteal artery. Materials/Methods: Retrospective study was performed on 187 patients from October 2012 to December 2015 who received an nDES in the SFA and/or popliteal artery. Patients were divided into 3 groups (Table 1) and compared against for duplex based restenosis (>60%) rates, limb loss rates, and reintervention rates. Each patient’s Trans-Atlantic-Inter-Society-Consensus II (TASC-II) class was collected. Postoperative duplex was performed 1 week after the procedure, then every 3 months for the first year, then, every 6 months to check for patency. IBM-SPSS-22 was used for all analyses. Results: Average age of the patients was 64.65 ± 73.4 years. 101 patients had 101 procedures performed on the left lower extremity; 86 patients had 86 procedures performed on the right lower extremity; 123 patients were male and 64 were female. Average length of follow-up was 13.1±9.7 months. Most common indication for intervention was claudication, followed by critical limb threatening ischemia. Restenosis and reintervention by groups can be seen in Table 1. No patients experienced limb loss. There were no statistically significant differences between any of the 3 groups and their limb loss, restenosis, or reintervention rates. Conclusions: Despite having multiple proven effects in improving certain clinical outcomes and a proven protective effect on endothelium by decreasing endothelial vascular reactivity, metformin does not appear to reduce restenosis or reintervention rates in patients receiving lower extremity nDESs in the SFA and/or popliteal artery.

AbstractOrthopaedic procedures can affect patients' ability to perform activities of daily living, such as driving automobiles or other vehicles that require coordinated use of the upper and lower extremities. Many variables affect the time needed before a patient can drive competently after undergoing orthopaedic surgery to the extremities. These variables include whether the patient underwent upper or lower extremity surgery, the country in which the patient resides, whether the right or left lower extremity is involved, whether the dominant arm is involved, whether the extremity is in a cast or brace, whether the patient has adequate strength to control the steering wheel, and whether the patient is taking pain medication. The type and complexity of the procedure also influence the speed of return of driving ability. Few studies provide definitive data on driving ability after upper or lower extremity surgery. Patients should be counseled not to drive until they can control the steering wheel and the pedals competently and can drive well enough to prevent further harm to themselves or to others. This review discusses the limited recommendations in the literature regarding driving motorized vehicles after upper or lower extremity orthopaedic surgery.

Iliac vein compression syndrome (IVCS) or May–Thurner syndrome occurs predominantly in young to middle-aged women. Here we reported a case of IVCS in a 5-year-old boy. The child was admitted to our vasculocardiology department with left lower extremity that had been swollen for 1 month. Blood tests revealed coagulation routine and platelets in the normal ranges. Computer tomography angiography (CTA) and magnetic resonance imaging (MRI) showed the left common iliac vein had become narrow before it entered the right common iliac vein. To further clarify, we performed angiography, which clearly showed the stenosis and the blood return of the left common iliac vein. So IVCS was diagnosed. What is more, we found the aorta descended to the right of the spine, and this may be the reason for the apparent compression of the left common iliac vein. Given the young age and mild symptoms of the child, the treatment was conservative mainly including elevation of the affected limb, wearing medical elastic socks, and short-term oral aspirin for anticoagulation. Meanwhile, the boy is being followed up closely. If the swelling of the left lower extremity significantly increases, stent placement may need to be considered in the future.

The Impact

The mechanics of moving along a curved path suggest that runners must change their body positions and thus adjust their lower extremity function as they accomplish a track turn. The purpose of the present study was to investigate the changes in the kinetics and kinematics of the lower extremity as runners proceed around the turn of a 400-m track (radius 31.5 m). Five skilled runners served as subjects in the study and were required to perform 10 trials in three conditions, running at 6.31 m/s plus or minus 5% (4:15 min/mile pace). The right and left limbs on a track turn and the right limb on the straightaway were evaluated using ground reaction force data and kinematic data from high-speed film. Statistical analysis of the 18 ground reaction force variables and 4 kinematic variables suggested that the right and left limbs at the midpoint of the track turn were asymmetrical and that most of the differences occurred in the first portion of the footfall Significant differences were found in the touchdown angle, maximum pronation angle, all mediolateral variables, and in the vertical variables describing the collision phase of the footfall (p < .05). The data suggest that the etiologies of injuries to the right and left lower extremity differ, with right foot injuries being of the impact type and left leg injuries being of the overpronation type.

Background Lower extremity peripheral arterial disease (PAD) is a common medical condition causing substantial morbidity. Limited data exist on whether discrepancies in PAD prevalence exist between the lower extremities using resting ankle-brachial indices (ABIs) and postexercise pressures. Objective We predicted the prevalence of PAD between the lower extremities. Methods and Results Consecutive patients who had undergone a noninvasive arterial lower extremity study at Mayo Clinic, Rochester, MN, between January 1996 and December 2012 with suspected PAD were retrospectively reviewed. We identified 12,312 consecutive patients who underwent an arterial lower extremity and an exercise treadmill study. Prevalence of PAD was assessed at rest and after exercise using two criteria: a resting ABI ≤ 0.90 and a postexercise pressure decrease of > 30 mm Hg. Mean age was 67 ± 12 years and there were 4,780 (39%) women studied. At rest, we found a higher prevalence of PAD on the left extremity (27.4%) compared with the right (24.6%) (p < 0.0001). After exercise, we found a higher prevalence of PAD on the right extremity (25.1%) compared with the left (19.0%) (p < 0.0001). These discrepancies between the prevalence of PAD at rest and after exercise were present in women and men. Conclusion Using validated criteria of a resting ABI of ≤ 0.90 and postexercise ankle pressure decrease > 30 mm Hg, our results suggest that there is a significantly higher prevalence of PAD in the left lower extremity at rest, in contrast to a greater prevalence of abnormal postexercise testing in the right lower extremity. The reason(s) of these discrepancies remain to be studied.

Introduction: In this study, the aim is to discuss the cases of lower extremity and perianal burns at the burn center in the southeast Anatolia of Turkey. Material and methods: A 4-year retrospective study was conducted on 775 patients who had been admitted to Gazi Yaşargil Training and Research Hospital Burn Centre with lower extremity and perianal burn injuries between January 2016 and January 2020. Results: Of the patients, 427 were male and 348 were female. Scald burns are most commonly affect the perianal and lower extremities. The right lower extremity was affected in 602 (77.7%) patients, the left lower extremity was affected in 574 (74.1%) patients and the perineum was affected in 70 (9.0%) patients. Most burn injuries occur in individuals between 0 to 4 years old, and the rate of burn injuries gradually decreases in individuals outside of this age range. No patient underwent colostomy for perianal burns. Conclusion: Early, aggressive and extensive debridement, in addition to adequate antimicrobial therapy, should be performed as the basis of treatment.

Background Step-up exercises often are suggested for strengthening the hip abductor muscles and improving balance in older adults. Little is known, however, about whether the forward or lateral version of these exercises is best for activating the hip abductor muscles. Objective The purpose of this study was to examine the electromyographic (EMG) amplitude of the gluteus medius (GM) muscles bilaterally during forward and lateral step-up exercises. Design The study design involved single-occasion repeated measures. Methods Twenty-seven community-dwelling adults (7 men and 20 women) with a mean (SD) age of 79.4 (8.0) years performed forward and lateral step-up exercises while the surface EMG activity of the GM muscles was recorded bilaterally. Pressure switches and dual forceplates were used to identify the ascent and descent phases. Subjects were instructed to lead with the right lower extremity during ascent and the left lower extremity during descent. Differences in normalized root-mean-square EMG amplitudes with exercise direction (forward versus lateral) and phase (ascent versus descent) were examined by use of separate repeated-measures analyses of variance for the right and left lower extremities. The alpha level was set at .05. Results Gluteus medius muscle EMG activity was significantly greater for lateral than for forward step-up exercises for the left lower extremity during the ascent phase and for both lower extremities during the descent phase. In addition, right GM muscle EMG activity was significantly greater during ascent than during descent for both exercise directions. Limitations Study limitations include use of a convenience sample and collection of limited information about participants. Conclusions Step-up exercises are effective in activating the GM muscle, with lateral step-up exercises requiring greater GM muscle activation than forward step-up exercises. Further study is needed to determine whether exercise programs for hip abductor muscle strengthening in older adults should preferentially include lateral over forward step-up exercises.

Immune-mediated necrotizing myopathy, a new subgroup of inflammatory myopathies, usually begins with subacute onset of symmetrical proximal muscle weakness. A 35-year-old male presented with severe asymmetric iliopsoas atrophy and low back pain with a previous history of left lower extremity weakness. Although his first left lower extremity weakness occurred 12 years ago, he did not receive a clear diagnosis. Magnetic resonance imaging of both thigh muscles showed muscle edema and contrast enhancement in patch patterns, and the left buttock and thigh muscles were more atrophied compared to the right side. Serum creatine kinase levels were elevated, and serologic testings were all negative. Genetic testing using a targeted gene-sequencing panel for neuromuscular disease including myopathy identified no pathogenic variants. Muscle biopsy on the right vastus lateralis showed scattered myofiber necrosis with phagocytosis and an absence of prominent inflammatory cells, consistent with seronegative necrotizing myopathy. Thus, unusual asymmetric muscle weakness and atrophy can be a manifestation of inflammatory myopathy.
