Christine A Ho
Although cubitus varus has been regarded as a purely cosmetic problem in the pediatric population, symptomatic elbow instability, and ulnar neuropathy from the mechanical axis malalignment have been reported in adults. This overview discusses the biomechanical axis disruption that leads to soft tissue and morphologic bony alterations in the elbow and offers a compelling argument for corrective osteotomy to treat pediatric cubitus varus.

PURPOSE: Osteo-chondrodysplasias are a rare cause of limb malalignment, deformity and degenerative joint disease. Earlier in life, deformities may be managed with bony realignment and soft tissue releases; however, as degenerative changes progress, arthroplasty may be considered. There are limited reports examining shoulder arthroplasty in this population. This study aims to assess pain relief, function, and re-operation rate of shoulder arthroplasty in patients with osteo-chondrodysplasias...

We assessed which combinations of risk factors can classify adults who develop accelerated knee osteoarthritis (KOA) or not and which factors are most important. We conducted a case-control study using data from baseline and the first 4 annual visits of the Osteoarthritis Initiative. Participants had no radiographic KOA at baseline (Kellgren-Lawrence [KL] < 2). We classified 3 groups (matched on sex): 1) accelerated KOA: >1 knee developed advance-stage KOA (KL = 3 or 4) within 48 months, 2) typical KOA: >1 knee increased in radiographic scoring (excluding those with accelerated KOA), and 3) No KOA: no change in KL grade by 48 months...

It is controversial whether the surgical restoration of sagittal balance and spinopelvic angulation in a single level lumbar degenerative spondylolisthesis results in clinical improvements. The purpose of this study to systematically review the available literature to determine whether the surgical correction of malalignment in lumbar degenerative spondylolisthesis correlates with improvements in patient-reported clinical outcomes. Literature searches were performed via Ovid Medline, Embase, CENTRAL and Web of Science using search terms "lumbar," "degenerative/spondylolisthesis" and "surgery/surgical/surgeries/fusion"...

Optimal function of left ventricular assist devices (LVADs) depends on proper alignment of the inflow cannula (IC). Quantitative guidelines for IC angulation are lacking because of variation in cardiac geometry and difficulty in analyzing three-dimensional (3D) cannula orientation relative to the left ventricle (LV). Based on contrast-enhanced computed tomography images from five normal and five clinically malpositioned IC cases in patients with HeartMate II LVADs, we developed a method for 3D quantification of IC malpositioning...

OBJECTIVES: We hypothesize that the anatomic center of the distal tibia is just lateral and anterior to the center of the distal tibia articular surface in the coronal and sagittal planes respectively, and that placement of the nail along this axis results in improved rates of malalignment when treating distal tibia fractures. DESIGN: Retrospective study SETTING:: One level I and one level II trauma center PATIENTS/PARTICIPANTS:: 203 distal tibia fractures treated with IMN (primary cohort) whose main fracture line extended within 5 cm of the plafond to evaluate the rate of malalignment with distal nail placement...

BACKGROUND: Minimally invasive surgical operation of intramedullary (IM) nailing is a standard technique for treating diaphyseal fractures. However, in addition to its advantages, there are some drawbacks such as the frequent occurrence of malalignment, physical fatigue and high radiation exposure to medical staff. The use of robotic and navigation techniques is promising treatments for femoral fractures. MATERIALS AND METHODS: This paper presents a novel robot-assisted manipulator for femoral shaft fracture reduction with indirect contact with the femur...

BACKGROUND: The goal of patellofemoral arthroplasty (PFA) is to replace damaged cartilage and correct underlying deformities to reduce pain and prevent maltracking. We aimed to determine how PFA modifies patellar height, tilt, and tibial tuberosity-trochlear groove (TT-TG) distance. The hypothesis was that PFA would correct trochlear dysplasia or extensor mechanism malalignment. METHODS: The authors prospectively studied a series of 16 patients (13 women and 3 men) aged 64...

RATIONALE: High tibial osteotomy (HTO) has been used widely for medial compartment knee osteoarthritis to correct the deformity and relieve symptoms, especially in young patients who are willing to maintain the high activity level. However, the change of bone morphology, ligament imbalance, limb malalignment, and other complications may influence the short-term outcomes of HTO. Some cases may even require conversion to TKA shortly after HTO because of the loss of correction or pain due to accelerated osteoarthritis...

Lower limb length discrepancy and malalignment in paediatric orthopaedics constitute a set of acquired or malformative structural pathologies. These anomalies, which may alter statics of lower limbs, are susceptible to engender an asymmetry of mechanical constraints' distribution across joints, and thus to promote the onset of arthritic phenomenons. The purpose of this review's article is to define the limits of tolerance of the various malformations and describe the innovative techniques available in order to correct them...

The proximal humeral locking plate (PHLP) is a recently developed fixed-angle implant that is an option for open reduction-internal fixation of an unstable displaced proximal humeral fracture. Various articles have reported successful outcomes using the PHLP when compared with other implant designs. However, many complications still occur with use of the PHLP, such as avascular necrosis of the humeral articular fragment, malreduction (particularly varus malalignment), and screw penetration. These complications are related to the difficulty in fixation of this particular type of fracture, as well as ineffective surgical technique...

PURPOSE: Patient-specific instruments (PSIs) are already in relatively common use, and their post-operative radiographic results are equal to those for total knee arthroplasty (TKA) with conventional instrumentation. PSI use requires a preoperative MRI scan, CT scan, or a combination of MRI and a long-leg standing radiograph. However, there is no consensus as to which of these modalities, MRI or CT, is the preferred imaging modality when performing TKA with PSIs. METHODS: This systematic literature review and meta-analysis studied the differences in alignment outliers between CT- and MRI-based PSI for TKA...

BACKGROUND: There is a renewed interest in joint preservation surgery, and lateral opening wedge distal femoral osteotomy (DFO), a joint-preserving procedure, has been used to treat symptomatic genu valgum when the deformity originates in the distal femur. QUESTIONS/PURPOSES: This study aimed to measure the accuracy of lateral opening wedge DFO in achieving deformity correction using radiographic parameters. In addition, the ability of lateral opening wedge DFO to improve patient outcomes as measured by Short Form Health Survey (SF-36) scores and American Academy of Orthopedic Surgeons (AAOS) lower limb module (LLM) scores leading to successful joint preservation was assessed...

OBJECTIVE: An oblique single cut rotation osteotomy enables correcting angular bone alignment in the coronal, sagittal and transverse planes, with just a single oblique osteotomy, and by rotating one bone segment in the osteotomy plane. However, translational malalignment is likely to exist if the bone is curved or deformed and the location of the oblique osteotomy is not obvious. METHODS: In this paper we investigate how translational malalignment depends on the osteotomy location...
