Restoration of neutral mechanical alignment of the lower limb is an important factor in the treatment of unicompartmental arthrosis. Traditionally, medial opening wedge high tibial osteotomy has been widely performed to correct varus malalignment with unicompartmental arthrosis. However, an ideal indication for the high tibial osteotomy is the knee with metaphyseal tibial varus malalignment. The basic principle of corrective osteotomy is performing an osteotomy at the center of the deformity to prevent abnormal joint line obliquity. If pathologic distal femoral varus deformity is the cause of genu varum, the osteotomy should be performed in the distal femur. Reports of medial opening wedge distal femoral osteotomy (DFO) to correct varus malalignment are rare. We present a case of this very rare and challenging condition in a 47-year-old male, which was successfully treated by medial opening wedge DFO.

Globally, the elderly population is increasing rapidly, which means that the number of deformity correction operations for elderly spine deformity patient has increased. On the other hand, for aged patients with deformity correction operation, preoperative considerations to reduce the complications and predict a good clinical outcome are not completely understood. First, medical comorbidity needs to be evaluated preoperatively with the Cumulative Illness Rating Scale for Geriatrics or the Charlson Comorbidity Index scores. Medical comorbidities are associated with the postoperative complication rate. Managing these comorbidities preoperatively decreases the complications after a spine deformity correction operation. Second, bone densitometry need to be checked for osteoporosis. Many surgical techniques have been introduced to prevent the complications associated with posterior instrumentation for osteoporosis patients. The preoperative use of an osteogenesis inducing agent

PURPOSE: The objective was to evaluate the relationship between side-to-side differences of lateral femoral bowing and varus knee deformity based on two-dimensional (2D) assessment in unilateral total knee arthroplasty (TKA). MATERIALS AND METHODS: A total of 143 patients with varus knee osteoarthritis who underwent unilateral TKA were enrolled. We evaluated the side-to-side differences of the frontal lower limb alignment by assessing lateral femoral bowing, anatomical medial distal femoral angle, and anatomical medial proximal tibial angle (aMPTA). RESULTS: The average values of all anatomical indices were significantly different between the operated side and the non-operated side (p < 0.05). The side-to-side difference in hip knee ankle (HKA) angle had a statistically significant correlation with that in lateral femoral bowing (intraclass correlation coefficient, 0.259; p=0.002) and that in aMPTA. Linear regression analysis showed 0.199° of side-to-side difference in lateral femoral bowing was associated with 1° of side-to-side difference in bilateral HKA angle. CONCLUSIONS: The side-to-side difference in lateral femoral bowing showed a tendency to increase in proportion to varus knee deformity based on 2D assessment in unilateral TKA patients.

OBJECTIVE: To find factors affecting hip and femoral deformities in children with spastic cerebral palsy (CP) by comparing various clinical findings with imaging studies including plain radiography and computed tomography (CT) imaging. METHODS: Medical records of 709 children with spastic CP who underwent thorough baseline physical examination and functional assessment between 2 to 6 years old were retrospectively reviewed. Fifty-seven children (31 boys and 26 girls) who had both plain radiography of the hip and three-dimensional CT of the lower extremities at least 5 years after baseline examination were included in this study. RESULTS: The mean age at physical examination was 3.6 years (SD=1.6; range, 2–5.2 years) and the duration of follow-up imaging after baseline examination was 68.4 months (SD=22.0; range, 60–124 months). The migration percentage correlated with motor impairment and the severity of hip adductor spasticity (R1 angle of hip abduction with knee flexion). The femoral neck and shaft angle correlated with the ambulation ability and severity of hip adductor spasticity (R1 and R2 angles of hip abduction with both knee flexion and extension). CONCLUSION: Hip subluxation and coxa valga deformity correlated with both dynamic spasticity and shortening of hip adductor muscles. However, we found no correlation between femoral deformities such as femoral anteversion, coxa valga, and hip subluxation.

Polyacrylamide hydrogel is a widely used filler material in cosmetic procedures performed on the face and breasts. Recently, however, complications including inflammation, deformity, and pain have been reported. The present article addresses unregulated materials/products injected as dermal fillers. The authors report a case involving a 29-year-old woman who developed severe facial pain after undergoing a cosmetic procedure with injectable triamcinolone and hyaluronidase. Two months later, the pain spread to her upper and lower limbs, and abdomen, which eventually led to the the development and diagnosis of complex regional pain syndrome (CRPS) in the upper limbs. The authors hypothesize that CRPS in the upper limbs was responsible for the facial pain through sensitization of third-order neurons and the trigeminal nucleus caudalis extending to the upper cervical segments.

Osteotomy around the knee is a widely considered surgical procedure for osteoarthritis with lower extremity malalignment. High tibial osteotomy (HTO) is performed for varus deformity, while distal femur osteotomy (DFO) is performed for valgus deformity. However, if the correction is insufficient, double osteotomy can also be considered. This report included the basic principles and current concepts of patient selection and preoperative planning in osteotomy around the knee.

PURPOSE: This study examined the effects of the lower limb alignment on the pelvis, hip, and knee kinematics in people with genu varum during stair walking. METHODS: Forty subjects were enrolled in this study. People who had intercondylar distance ≥4cm were classified in the genu varum group, and people who had intercondylar distance < 4cm and intermalleolar distance < 4cm were placed in the control group. 3D motion analysis was used to collect the pelvis, hip, and knee kinematic data while subjects were walking stairs with three steps. RESULTS: During stair ascent, the genu varum group had decreased pelvic lateral tilt and hip adduction at the early stance phase and decreased pelvic lateral tilt at the swing phase compared to the control group. At the same time, they had decreased minimal hip adduction ROM at the early stance and decreased maximum pelvic lateral tilt ROM and minimum hip rotation ROM at the swing phase. During stair descent, the genu varum group had decreased pelvic lateral tilt at the early stance and decreased pelvic lateral tilt and pelvic rotation at the swing phase. In addition, they had decreased pelvic frontal ROM during single limb support and increased knee sagittal ROM during the whole gait cycle. CONCLUSION: This study suggests that a genu varum deformity could affect the pelvis, hip and knee kinematics. In addition, the biomechanical risk factors that could result in the articular impairments by the excessive loads from lower limb malalignment were identified.

STUDY DESIGN: Literature review. OBJECTIVE: The aim of this article is to introduce the EOS imaging device, with a focus on spinal and pelvic alignment. SUMMARY OF LITERATURE REVIEW: The EOS imaging device can obtain images of spinal and pelvic alignment with almost no distortion, using a low radiation dose. MATERIALS AND METHODS: We searched for studies related to the use of EOS imaging device for spinal and pelvic alignment. RESULTS: The EOS is not only capable of simultaneously obtaining paired anteroposterior and lateral X-ray images with a low radiation dose, but also can reconstruct the image as if it was acquired in the patient's reference plane, limiting the distortion to the patient's thickness instead of the whole distance between the source and detector. The EOS device also has the advantage of accurately measuring the sagittal alignment of the spine and pelvis and the torsional deformity of the lower limbs, as the subject can be imaged while standing upright in a weight-bearing posture. CONCLUSIONS: EOS is a new diagnostic technique that can detect spinal and pelvic alignment and deformities of the lower limbs under weight-bearing conditions with a low radiation dose.

Klinefelter's syndrome is the most common congenital abnormality that causes primary hypogonadism. It is associated with diseases that predominantly affect women, such as systemic lupus erythematosus (SLE), and it can sometimes cause veno-occlusive disease. We experienced a case of Budd-Chiari syndrome (BCS) in a 33-year-old man with Klinefelter's syndrome presented with hematemesis and edema in both lower extremities. The clinical and laboratory findings were compatible with SLE, antiphospholipid syndrome, and BCS. To the best of our knowledge, this is the first case report to describe a simultaneous presentation of these four clinical syndromes in a single patient.

BACKGROUND: Paget's disease of bone leads to change in the shape and size of the bone and results in reduced bone strength, leading to the complications of deformity, arthritis, and fracture. Due to unknown reasons, Paget's disease is rare in Asian descendants. We report the cases of Paget's disease who visited our institute for 15 years and reviewed the literatures. METHODS: We retrospectively reviewed the medical records and radiograms of 8 patients (6 female and 2 male) who were diagnosed as Paget's disease of bone. Diagnosis was confirmed by typical radiological feature in the involved skeletons and/or pathologic findings. RESULTS: Pelvis, skull and spine were three most frequently involved bones. All involved bones in our cases showed changes in shape and trabecular pattern which resulted in bowing of lower extremity, secondary osteoarthritis, compression fracture of spine and enlargement of skull. Mean follow time was 4.71 years and all patient were treated bisphosphonate (BP). Use of BP controlled the level of serum alkaline phosphatase level effectively. CONCLUSIONS: We have reviewed eight patients who were previously diagnosed as Paget's disease of bone in our institute. We could identify typical radiologic and clinical findings such as bowing deformity of long bone, secondary osteoarthritis, compression fracture and osteomyelitis of mandible that deteriorated the quality of their living.
