Outcome of Percutaneous Tibial Osteotomy in Children with Genu Varum Deformity

Outcome of Percutaneous Tibial Osteotomy in Children with Genu Varum Deformity

Non-Surgical Strategies for Managing Skeletal Deformities in a Child with X-Linked Hereditary Hypophosphatemic Ricket: Insights and Perspectives.

This case report sheds light on the management of skeletal deformity in a young child with X-linked hypophosphatemia (XLH), emphasizing the significance of a timely orthotic intervention alongside pharmacological treatment, which is a strategy not frequently highlighted in the XLH literature. The patient, a 2-year-and-7-month-old female, presented with classic XLH symptoms, including short stature, pronounced genu varum, and hypophosphatemia, with deformities observed in both the coronal and sagittal planes of the femur and tibia. Despite initial reliance on pharmacotherapy, which proved insufficient for skeletal realignment, the integration of orthotic treatment at age 3 marked a pivotal turn in the management strategy. By the age of 5 years and 9 months, this combined approach yielded significant improvements: the deformities in the femur and tibia were notably corrected, tibial torsion was addressed, and enhanced limb alignment was achieved, as corroborated by radiographic evidence. This case underscores the effectiveness of orthotic intervention as a critical and underemphasized adjunct to pharmacological therapy in managing XLH in early childhood. It advocates for the early inclusion of orthotic measures to optimize treatment outcomes and expand the range of management strategies for limb deformities.

A Rare Case of Osteogenesis Imperfecta Type V

Osteogenesis imperfecta (OI) is a hereditary bone condition characterised by fragile bones to be more susceptible to fracture. We reported a rare case of a 6-year-old girl with OI Type V and hyperplastic callus formation. She presented with recurrent fractures since birth with no family history of a similar condition. Clinically, her height and weight were lower than the 5th percentile for her age. She had deformities with limitation of movement of elbows, kyphoscoliosis, a more extensive right thigh, and anterior bowing of both legs. Radiographic examination revealed interosseous membrane of forearm ossification, dislocation of the right radial head and hyper-callosity of both femurs during fracture healing. She was treated with intravenous pamidronate and had posterior instrumentation and fusion for scoliosis and intramedullary rodding for her femur fracture. On a recent follow-up at the age of 16 years, she was ambulating well with no progression of the spinal deformity.

A Child with Severe Bilateral Tibia Vara: Treatment with Computer-Assisted Gradual Correction Utilizing Hexapod External Fixator

A 7-year-old obese boy presented to the Paediatric Orthopaedic clinic with a complaint of worsening bilateral knee bowing. He was initially seen for the same problem in another hospital at the age of 3. The bowing of the leg was associated with pain over the lateral aspect of both knees. He was able to walk but unable to run or participate in sports due to the deformity and knee pain. On examination, the child had a waddling gait and lateral thrust due to severe bilateral genu varus. The range of motion of bilateral knee joints was 0 to 110 degrees. The knee intercondylar distance was markedly increased and there was bilateral tibial torsion. No limb length discrepancy and neurovascular examination was normal. The radiograph revealed features of infantile tibia vara (Blount disease). Bilateral proximal tibia temporary hemiepiphysiodesis was attempted but no correction of the deformity was achieved due to implant failure. His parents were then counseled to let him undergo gradual deformity correction surgery using a ring external fixator (hexapod system). The bilateral varus deformity was corrected after 4 months, and the patient was able to walk normally.

Severe genu varus deformity does not affect enhanced recovery after surgery total knee arthroplasty outcomes.

Enhanced recovery after surgery (ERAS) has been increasingly adopted in orthopaedic surgery. Although not an exclusion criterion, patients undergoing total knee arthroplasty (TKA) with preoperative severe varus deformity may be less likely to be enrolled for ERAS. This study aimed to compare the success of ERAS TKA between patients with severe preoperative varus deformities (≥ 15° varus) and the control group (< 15° varus to 14° valgus). Our secondary aim was to compare postoperative complications and functional outcomes between the two groups. 310 TKAs performed from August 2019 to February 2021 were analyzed with a follow-up of 6 months postoperatively. The primary outcome, ERAS TKA success, was defined as length of hospital stay of < 24h. Other parameters included 30-day postoperative complications and clinical outcomes such as the original Oxford Knee Score (OKS), the Knee Society Knee (KSKS) and Function Score (KSFS), Visual Analog Scale for Pain (VAS-P), 36-Item Short-Form Health Survey (SF-36) Physical Component Summary (PCS) and SF-36 Mental Component Summary (MCS). There were 119 patients in the severe deformity group and 191 patients in the control group. There were no significant differences in ERAS success between the severe deformity group and control group, with both groups achieving similarly high rates (> 90%) of ERAS success. There were also no differences in 30-day postoperative complications and 6-month postoperative clinical outcomes. Patients with severe preoperative varus deformity undergoing ERAS TKA achieved high ERAS success rates (> 90%). Genu varum is not a contraindication for ERAS TKA.

The Biomechanical and Functional Status of Patients with Knee Osteoarthritis - A Cross Sectional Study

Background and Objectives: Knee deformity associated with osteoarthritis (OA) is one of the most common complications reported to orthopaedic surgeons. Genu valgum and genu varum are the most commonly occurring deformities due to knee osteoarthritis. When there is progression in degeneration due to osteoarthritis, deformities tend to worsen and will eventually lead to reduction in cadence rate, hindfoot angle, range of motion in both hip and knee. Thus, this study is conducted to analyze these parameters like cadence, hindfoot angle, hip internal flexion, knee flexion, WOMAC scale and VAS pain rating scale between the groups of individuals with genu valgum and genu varum deformity. Methodology: A convenient division was made of a total of 80 knee osteoarthritis (OA) patients into two groups by measuring their medial tibiofemoral angle, namely genu valgum and genu varum. The patients were evaluated for various parameters including gait cadence, reduced knee flexion, hip internal rotation, hind foot angle, WOMAC scale, and VAS pain scale. The discrepancies in these parameters were analyzed between the genu valgum and genu varum groups. This study design represents a cross-sectional approach. Results: The Independent t-test was used to examine the results among the groups, with a significance level set at p ≤ 0.05. Considerable statistical changes were observed in cadence, hindfoot angle, knee flexion ROM, and hip internal rotation ROM, with corresponding p-values of 0.0006, 0.049, 0.002, and 0.01, respectively. However, no significant differences were found in the case of the WOMAC scale and VAS pain rating scale between the groups with genu valgum and genu varum deformities, as their p-values were considerably higher than the significance level (0.169, 0.948). Conclusion: The objective of the study was to gain insight into the biomechanical and functional condition of individuals suffering from knee osteoarthritis. Substantial differences were observed between the groups regarding cadence, hindfoot angle, knee flexion range of motion (ROM), and hip internal rotation ROM. However, when evaluating the WOMAC scale and VAS pain rating scale, both groups exhibited nearly identical values, indicating a lack of statistical significance in these outcome measures. Keywords: Knee osteoarthritis, genu valgum, genu varum, tibiofemoral angle, cadence, hindfoot angle, knee flexion ROM, hip internal rotation ROM, WOMAC scale, VAS scale.

Do Patient Sex and Age Affect Hemiepiphysiodesis Outcomes?

(1) Background: The purpose of this study was to assess the effects of sex and age on the outcomes of hemiepiphysiodesis performed for genu valgum and varum deformity correction. (2) Methods: We analyzed patients who had undergone O-Plate hemiepiphysiodesis due to genu valgum or varum in the period of 2020-2023. The study group comprised 22 females and 20 males aged between 3 and 14 years at the time of surgery. Age-stratification yielded a subgroup of 3-10-year-olds (16 patients, 20 treated limbs) and a subgroup of 11-14-year-olds (26 patients, 28 treated limbs). We assessed the following parameters: hospital stay duration, deformity correction time, MAD correction, amount of angular correction, correction velocity, correction rate, complete deformity correction, deformity recurrence, surgery duration, and complications. (3) Results: The mean follow-up was 19 months. The mean surgery time in the subgroup of 3-10-year-olds (25.62 min) was significantly longer than that in the subgroup of 11-14-year-olds (22.81 min, p = 0.018). The mean deformity correction time in the male subgroup (11.33 months) was significantly shorter than that in the female subgroup (15.87 months, p = 0.013). A comparison of the subgroups stratified by age yielded a mean amount of angular correction of 10.5° in the younger children, which was significantly higher than that of 7.2° achieved in the older children; p = 0.027. The difference in mean correction velocity between 3-10-year-old children (4.03 mm/month) and that in 11-14-year-old children (1.39 mm/month) was statistically significant; p = 0.031. The mean rate of correction was 0.49°/month in females and 0.89°/month in males, with the latter rate significantly greater; p = 0.023. The difference in the mean rate of correction between the younger (1.08°/month) and the older subgroup (0.59°/month) was also significant; p = 0.018. A significant difference in terms of deformity recurrence rates was observed between the younger subgroup (66.67%) and older subgroup (only 10.53%); p = 0.005. (4) Conclusions: Patient sex had no significant effect on hemiepiphysiodesis outcomes; patient age has a considerable effect on hemiepiphysiodesis outcomes.

Comparison of the Effect between Traband and Brace on People with Genu Varum and Genu Valgum Deformities: A Systematic Review

Lower limb coronal malalignment correction by percutaneous osteotomy and schanz screws fixation.

Pediatric knee deformities are common, and the classic treatment is corrective osteotomy. The aim of this study to assess the safety and efficacy of percutaneous low-energy osteotomy and casting with shanz screws fixation in treatment of Genu varum in children equal or younger than 7 years. This is a prospective nonrandomized case series study was conducted. A total of 38 patients (total of 60 limbs: 36 varus and 24 valgus) were treated by percutaneous low-energy osteotomy and casting with shanz screws fixation and observed over 2-5 years. Clinical and radiological outcomes were evaluated at the end of follow-up period by standing scanogram which enabled tibiofemoral angles and the mechanical axis to be measured and the rate of complications. There was a statistically significant improvement of the radiographic parameters in the form of tibiofemoral angle and MAD. Clinically, all the cases were completely corrected just one patient (two limbs) complicated by over-correction but statically non-significant and. pin tract infection in shanz screws fixation was noticed in one Patient. Percutaneous low-energy osteotomy and casting with shanz screws fixation is a simple, safe, and effective method in dealing with 7 years and younger children with pathological knee deformities. Level of evidence: Therapeutic level IV.

Multi-segment osteotomy with interlocking intramedullary nail fixation in the treatment of lower limb deformity in older children with hypophosphatemic rickets.

Malformations of the lower limbs caused by hypophosphatemic rickets in older children are mostly complex, occurring on multiple planes without a single apex and showing arcuate bending of the diaphysis combined with torsion deformity, and are difficult to correct. This study retrospectively investigated the effect of and indicators for multi-segment osteotomy with interlocking intramedullary nail fixation in the treatment of bony deformity caused by hypophosphatemic rickets. The clinical data of 21 hypophosphatemic rickets patients seen between August 2007 and March 2022 were collected. The age range of the patients at the first surgery was 11 years and 1 month old to 15 years and 3 months old, with an average age of 12 years and 8 months. There were 6 males and 15 females. All patients had abnormal alignment of their lower limbs, with 32 limbs having varus deformity and 10 limbs having valgus deformity. A total of 67 surgeries were performed across the 21 patients, including 24 cases of femoral osteotomy with antegrade intramedullary nail fixation, 6 cases of femoral osteotomy with retrograde intramedullary nail fixation, and 20 cases of tibial osteotomy with interlocking intramedullary nail fixation. A total of 34 limbs eventually underwent interlocking intramedullary nail fixation, 9 with genu valgum and 25 with genu varus. All 21 patients were followed up for a period of 14∼96 months, with an average of 42.6 months. The ends of the osteotomies achieved bony union in 4-9 months (average 6.8 months), after which normal weight-bearing walking could be resumed. No infection, vascular or neurological complications, or nonunion occurred. During postoperative follow-up, the alignment the lower limbs passed through zone 1 in 13 limbs, zone 2 in 12 limbs, and zone 3 in 5 limbs. The overall rate of an excellent effect was 83.3%. For lower limb deformity caused by hypophosphatemic rickets in older children, multi-segment osteotomy and strong fixation with interlocking intramedullary nails can achieve good correction outcomes.

Factors influencing correction rate following hemiepiphysiodesis using tension band plates for deformities around the knee: a multivariate analysis study.

The aim of this study was to appraise various factors influencing the correction rate in temporary hemiepiphysiodesis (THE) around the knee joint. Specifically, the study analysed the relationship of correction rate with age, gender, aetiology, type and location of deformity. The retrospective study included children who underwent THE for a coronal plane deformity (genu valgus or varum) around the knee joint (distal femur or proximal tibia) over a tenyear period (2010-2020). The primary outcome of interest was the correction rate of the deformity. Thirty-three children (27 females and 6 males) with a mean age of 8.1years involving 86 plates were included in the study. The mean correction achieved was 12.2° over a treatment period of 13.3months. Subgroup analysis showed significant differences between the type (varus (0.8° per month), valgus (1.1° per month)) and the location of deformity femur (1.2° per month) and tibia (0.7° per month)]. On multivariate analysis, the location and the duration of treatment showed significant associations with the correction rate. The correction of coronal deformities following temporary hemiepiphysiodesis is influenced by several factors. Valgus, femoral and deformities in younger children correct at a faster rate. Location of deformity and duration of treatment emerged as potential factors affecting the correction rate.

Frequency of Genu Valgum and Genu Varum among the University Students and their Association with Gender and BMI

Background: Knee angular deformities such as genu varum and genu valgum are common conditions that can lead to further complications and affect an individual's quality of life. Factors like gender, body mass index (BMI), lifestyle, and nutritional status are thought to influence the development of these conditions. Objective: The primary aim of the study was to investigate the relationship between gender and BMI with the prevalence of genu varum and genu valgum among university students. Methods: A cross-sectional survey was conducted over six months, from February to July 2021, involving 140 university students aged between 18 and 25 years, who were independent in activities of daily living (ADLs). Subjects with neurological, psychological, congenital disorders, or systemic pathologies were excluded. BMI was calculated using a height-weight machine. Knee alignment was assessed using a goniometer to measure the Q-angle at both the left and right knees. Data analysis was performed using IBM SPSS Statistics version 25. Results: The prevalence of genu varum was higher in males (23 cases) compared to females (7 cases), while genu valgum was more common in females (24 cases) than in males (5 cases). No significant difference in the incidence of genu varum and genu valgum was noted with BMI for the left knee (p=0.422), but a significant association was found for the right knee (p=0.049). Gender was significantly associated with knee angular deformities, with p-values of less than 0.0001 for both knees. Conclusion: The study underscores a significant association of knee angular deformities with gender, and a lateral-specific correlation of BMI with the Q-angle of the right knee. These insights are crucial for developing gender-specific and BMI-inclusive strategies for the prevention and management of genu varum and genu valgum.

The Diagnostic Odyssey in Children and Adolescents With X-linked Hypophosphatemia: Population-Based, Case-Control Study.

X-linked hypophosphatemia (XLH) is a rare genetic disorder causing renal phosphate wasting, which predicates musculoskeletal manifestations such as rickets. Diagnosis is often delayed. To explore the recording of clinical features, and the diagnostic odyssey of children and adolescents with XLH in primary care electronic healthcare records (EHRs) in the United Kingdom. Using the Optimum Patient Care Research Database, individuals aged 20 years or younger after January 1, 2000, at date of recorded XLH diagnosis were identified using Systematized Nomenclature of Medicine Clinical Terms (SNOMED)/Read codes and age-matched to 100 controls. Recording of XLH-related clinical features was summarized then compared between cases and controls using chi-squared or Fisher's exact test. In total, 261 XLH cases were identified; 99 met the inclusion criteria. Of these, 84/99 had at least 1 XLH-related clinical feature recorded in their primary care EHR. Clinical codes for rickets, genu varum, and low phosphate were recorded prior to XLH diagnosis in under 20% of cases (median of 1, 1, and 3 years prior, respectively). Rickets, genu varum, low phosphate, nephrocalcinosis, and growth delay were significantly more likely to be recorded in cases. This characterization of the EHR phenotypes of children and adolescents with XLH may inform future case-finding approaches to expedite diagnosis in primary care.

Novel subtype of coxitis knee associated with acetabular dysplasia of the hip: a case series

BackgroundMultiple joint arthritis patterns require a comprehensive understanding to optimize patient management. This study aimed to present a patient cohort that deviated from known definitions of coxitis knee (CK), identifying and characterizing this atypical group.MethodsPatients undergoing both total hip arthroplasty and total knee arthroplasty between January 2008 and December 2018 were retrospectively reviewed. The patients were classified into a typical coxitis knee group (classic, long leg arthropathy, and windswept deformity) and an atypical coxitis knee group. Leg-length discrepancy, body mass index (BMI), and radiographic parameters of the groups were compared and analyzed.ResultsA total of 31 patients were allocated to the typical coxitis knee group (n = 10), and atypical coxitis knee group (n = 21). In the atypical group, 27 hips were involved, of which 21 had acetabular dysplasia, 5 exhibited subchondral insufficiency fracture-like changes, and only 1 had classic osteoarthritis. Among the 27 knees undergoing total knee arthroplasty, 26 showed varus alignment, 1 was within the normal range, and none was valgus. Acetabular dysplasia involved ipsilateral (n = 1), contralateral (n = 14), and bilateral (n = 6) hips, showing atypical coxitis knee. Patients with acetabular dysplasia were more likely to exhibit atypical CK.ConclusionMost patients in the cohort displayed acetabular dysplasia and contralateral varus knees, constituting a pattern referred to as acetabular dysplasia-associated gonarthritis. Identifying this novel subtype may have important clinical implications for regions with high risk factors, where acetabular dysplasia and constitutional genu varum are prevalent.Graphical

Novel co-occurrence of hypophosphatemic rickets with 46XY DSD (disorder of sex development) due to a CYP17A1 variant

17-α-hydroxylase deficiency causes a rare type of congenital adrenal hyperplasia (CAH). X-linked hypophosphatemic rickets (XLH) is a rare disorder caused by inactivating mutations in the PHEX gene. We report a novel co-occurrence of XLH with 46XY disorder of sex development due to 17-α-hydroxylase deficiency. A young child reared as a girl, presented as a toddler with genu varus, low phosphorus, normal calcium, and parathormone, and was treated as hypophosphatemic rickets. In early childhood, due to short stature and hypertension, the child was investigated for Turner syndrome. Ultrasound revealed intra-abdominal gonads and an absent uterus. The karyotype was 46XY. Investigations revealed low serum cortisol, renin, normal 17-hydroxyprogesterone, and aldosterone. A year later, a bilateral orchidectomy was performed. Two years later, she was referred to us for further management. Adrenocorticotrophic hormone (ACTH), cortisol, renin, deoxycorticosterone, and clinical exome were advised. She was lost to follow-up for 3 years. On follow-up in early adolescence, she was pre-pubertal; biochemical findings of hypophosphatemic rickets, elevated ACTH, low cortisol, and low normal aldosterone were noted. Clinical exome revealed variants in the CYP17A1 gene (homozygous) causing CAH (17-α-hydroxylase) and PHEX (hemizygous) gene causing XLH. Treatment with hydrocortisone, phosphate, cholecalciferol, and calcitriol was commenced. Hypertension is now well-controlled, but genu varus persists and may require surgical correction.

The Use of Dome Shaped Osteotomy and Plating in Correction of Genu Varum

The Use of Dome Shaped Osteotomy and Plating in Correction of Genu Varum

Intraoperative radiographic analysis and adjustment of the optimal position of plate in high tibial osteotomy.

When high tibial osteotomy is performed for genu varus deformity, it is not easy to determine the accurate placement of the plate. To determine a simple way to assess the position of the plate, to provide more effective mechanical support and to reduce the risk of implant rupture and vascular injury. Two human anatomical marks, the patellar ligament and semimembranosus, were connected and divided into four parts to identify points Ⅰ, Ⅱ, and Ⅲ. These points determined the areas for Tomofix placement: anterior, anterolateral, and lateral. Simulated internal fixation placed hole B of Tomofix at points Ⅰ (anterior), Ⅱ (anterolateral), and Ⅲ (lateral). We analyzed the pointing direction of the locking screws in Tomofix holes on MRI to assess potential injury risk to the popliteal neurovascular bundle. In the X-ray: holes B and C appeared as the plate in the anterior, only hole C appeared as the plate in the anterolateral, and none of the holes appeared as the plate in the lateral. In the general view of the sawbones, the screw pointed towards the popliteal neurovascular bundle when the plate was in the anterior. If a small number of holes on the plate is visible under fluoroscopy, then several lateral positions of the plate can be obtained; the direction of the screw tunnel tends to deviate from the popliteal neurovascular bundle with the posterior position of the plate.

Correction of angular deformities of knee in children using guided growth technique 8-plates

Background: Angular deformities of the knee, a common problem in the early years of life are frequently encountered in paediatric orthopaedics not only because of very high incidence of these deformities but also because of major parental concern in the present highly demanding sports oriented society. The purpose of this study was to discuss the role of 8-plate hemi-epiphysiodesis to correct angular deformities of the knee joint. Materials and methods: The study had total of 25 children with total 45 knees having varus or valgus angular deformities, of which 20 were bilateral and 5 were unilateral. All patients were symptomatic and were followed for regular intervals of 6 months to observe the change of the deformity. Results: The mean preoperative genu valgum deformity was 19.79 degrees (ranging from 13-35 degrees) and genu varum deformity was 17.29 degrees (9-25 degrees). 91.1% of the deformed knees were corrected fully at the mean final follow up period of 27 months, neutralizing the mechanical axis and correction of the deformity. Conclusions: 8-plate is technically simple and potent tool to correct genu valgum and varus deformities around knee in children without need for osteotomies in many children. Based on the low complication rate, patient acceptance, and the rapidity of improvement, this technique should be used as treatment of choice.

The Biomechanical and Functional Status of Patients with Knee Osteoarthritis - A Cross Sectional Study

Background and Objectives: Knee deformity associated with osteoarthritis (OA) is one of the most common complications reported to orthopaedic surgeons. Genu valgum and genu varum are the most commonly occurring deformities due to knee osteoarthritis. When there is progression in degeneration due to osteoarthritis, deformities tend to worsen and will eventually lead to reduction in cadence rate, hindfoot angle, range of motion in both hip and knee. Thus, this study is conducted to analyze these parameters like cadence, hindfoot angle, hip internal flexion, knee flexion, WOMAC scale and VAS pain rating scale between the groups of individuals with Genu valgum and genu varum deformity. Methodology: A convenient division was made of a total of 80 knee osteoarthritis (OA) patients into two groups by measuring their medial tibiofemoral angle, namely Genu valgum and genu varum. The patients were evaluated for various parameters including gait cadence, reduced knee flexion, hip internal rotation, hind foot angle, WOMAC scale, and VAS pain scale. The discrepancies in these parameters were analyzed between the Genu valgum and genu varum groups. This study design represents a cross-sectional approach. Results: The Independent t-test was used to examine the results among the groups, with a significance level set at p ≤ 0.05. Considerable statistical changes were observed in cadence, hindfoot angle, knee flexion ROM, and hip internal rotation ROM, with corresponding p-values of 0.0006, 0.049, 0.002, and 0.01, respectively. However, no significant differences were found in the case of the WOMAC scale and VAS pain rating scale between the groups with Genu valgum and genu varum deformities, as their p-values were considerably higher than the significance level (0.169, 0.948). Conclusion: The objective of the study was to gain insight into the biomechanical and functional condition of individuals suffering from knee osteoarthritis. Substantial differences were observed between the groups regarding cadence, hindfoot angle, knee flexion range of motion (ROM), and hip internal rotation ROM. However, when evaluating the WOMAC scale and VAS pain rating scale, both groups exhibited nearly identical values, indicating a lack of statistical significance in these outcome measures.

Association Between Lumbar Spine Disorder and Genovarum: A Population-Based Cross-Sectional Study.

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. 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. 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. An association between lumbar disorders and varus more than 20 degrees was found to be considerable.
