Two common complications that occur in cervical surgery are malalignment, particularly after multilevel laminectomies, and nonunions. In both clinical situations, prevention and early recognition are critical in its respective clinical management. In postlaminectomy kyphosis, the prevailing cause is an alteration in the normal spinal biomechanics. The exact incidence is unknown; however, when t...

Osteoarthritis is a syndrome affecting a variety of patient profiles. A European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis and the European Union Geriatric Medicine Society working meeting explored the possibility of identifying different patient profiles in osteoarthritis. The risk factors for the development of osteoarthritis include systemic factors (e.g., ...

I appreciate the insight provided by this letter to the authors regarding the issue of sagittal malalignment in this case report. Although the case report was directed at the postoperative seroma and potential relationship with the use of vancomycin, andwas not related to the sagittal alignment per se, the input provided in this case ismuch appreciated. In fact, I went back and remeasured the p...

diagnosis of knee osteoarthritis can be confirmed based on clinical and/or radiological features. the potential of a progressive disease can be prevented or decreased by earlier recognition and correction of associated factors. obesity and alignment especially varus malalignment are recognized factors of a progressive disease. both nonpharmalogical as well as pharmacological modalities of treat...

abstract   background: the purpose of this study was to evaluate the significance of the q angle with respect to the patella position. we assess the correlation between the q angles (calculated by clinical exam) in different positions and ct indices (with more impression on tttg).   method: atotal number of 68 knee joints of 50 cases entered the study. clinical examination was used to measure q...

Abstract Introduction Although arthroscopic acromioclavicular (AC) joint resection is a frequently performed procedure, the pathophysiology of non-traumatic AC degeneration still unclear. The purpose this study was to investigate whether shows typical pattern and it starts at posterior part with malalignment articular surfaces. Materials methods In retrospective monocentric diagnostic study, he...

Varus malalignment after total knee replacement is associated with a poor outcome. Our aim was to determine whether the same was true for medial unicompartmental knee replacement (UKR). The anatomical leg alignment was measured prospectively using a long-arm goniometer in 160 knees with an Oxford UKR. Patients were then grouped according to their mechanical leg alignment as neutral (5 degrees t...

BACKGROUND Quadriceps-sparing (QS) approach is considered to be the most minimally invasive surgery for total knee arthroplasty (TKA). We perform this meta-analysis to evaluate whether malalignment and malposition are more biased towards the QS approach compared to the traditional medial parapatellar (MP) approach, which is still controversial. METHODS According to the PRISMA guidelines, a co...

BACKGROUND Failure rates of knee ligament surgery may be high, and the impact of osseous alignment on surgical outcome remains controversial. Basic science studies have demonstrated that osseous malalignment can negatively affect ligament strain and that realignment procedures may improve knee joint stability. HYPOTHESIS/PURPOSE The purpose of this review was to summarize the clinical evidenc...
