BACKGROUND: Little is known about how bone cement and American Society of Anesthesiologists (ASA) classification influence the cardiovascular system in elderly patients with femoral-neck fractures treated with cemented hemiarthroplasty. Therefore, we performed a case-control study to investigate these questions and compared the following: 1) ≥ASA III with ≤ASA II patients who underwent cemented hemiarthroplasty; 2) cemented with cementless hemiarthroplasty in ≥ASA III patients. HYPOTHESIS: ASA classification influences the cardiovascular system during cemented hemiarthroplasty and bone cement influences intraoperative blood pressure [IBP] in patients rated ≥ASA III...

CONTEXT: Humeral plating osteosynthesis is controversial, particularly regarding the choice between anterior and lateral approach, data for which in the context of a low-income country are lacking. HYPOTHESIS: The anterior approach is an easy surgical technique, allowing good anatomic reconstruction. We hypothesize that the anterior approach is associated with fewer neurovascular lesions and functional sequelae than the lateral approach. MATERIALS AND METHODS: A retrospective study with assessment update was carried out over a period of 6 years 4 months from January 2010 to June 2016, with consecutive recruitment in the city of Yaoundé, Cameroon...

BACKGROUND: The functional and clinical benefit of minimally invasive total hip arthroplasty (THA) is well-known, but the literature reports impaired gait and posture parameters as compared to the general population, especially following use of the anterior minimally invasive approach, which has more severe impact on posture than the posterior approach. The reasons for this impairment, however, remain unexplained. We therefore conducted a surface electromyography (sEMG) study of the hip muscles liable to be affected by arthroplasty surgery: gluteus maximus (GMax), gluteus medius (GMed, tensor fasciae latae (TFL), and sartorius (S)...

BACKGROUND: The benefits and risks of a single-stage medial UKA remains a subject of debate because of the theoretically higher risk of complications and specifically blood loss. The aim of this study was to evaluate the perioperative blood loss, risks and the functional results of single-stage bilateral medial Oxford Unicompartmental Knee Arthroplasty (OUKA) compared to a standard unilateral medial OUKA procedure (control group). HYPOTHESIS: the blood loss observed during bilateral single-stage medial Oxford UKA is not different from that of the control group...

Idiopathic pes planus is common and usually physiologic. Decompensation, when it occurs, may be obvious or on the contrary difficult to identify, raising challenges in patient selection for surgical treatment. The physical examination of a child with pes planus must include an evaluation in the supine position, which helps to adjust the amount of correction during surgery. The many reported surgical procedures include repositioning (talus-reseating, subtalar implants, and calcaneo-stop screw), osteotomies, and joint fusions...

BACKGROUND: We investigated preoperative factors among demographic and clinical characteristics, as well as psychological factors that influence postoperative patient satisfaction, with the goal of assisting preoperative patient consultation for CTR. MATERIALS AND METHODS: We included 92 hands from 60 patients diagnosed with idiopathic carpal tunnel syndrome. We selected the following factors as possible preoperative predictors for patient satisfaction: age, sex, duration of symptoms, static two-point discrimination, the Semmes-Weinstein monofilament test, grip strength, electrophysiological category, and scores for the Boston Carpal Tunnel Questionnaire, the Pain Anxiety Symptoms scale, and the Center for the Epidemiological Study of Depression scale...

INTRODUCTION: The prevalence of shoulder pathology in wheelchair dependent patients is high. The shoulder joint is critical for maintaining independence but traditionally there has been reluctance to offer surgical intervention in view of perceived poor outcomes. The aim of this study was to provide patients and surgeons with a realistic overview of outcomes following surgical intervention for shoulder pathology in wheelchair dependent patients. METHODS: A systematic review of the online databases Medline and EMBASE was performed in September 2017...

BACKGROUND: Although asymptomatic mild limb length discrepancy (LLD) in children is generally treated non-operatively, there is limited high quality follow up data to support this recommendation. HYPOTHESIS: We hypothesized that there would be no association between LLD and arthritic changes with mild limb length discrepancy. MATERIALS AND METHODS: We studied 576 well-preserved cadaveric skeletons ranging from 40 to 79 years of age. Limb length discrepancy was based on combined femoral and tibial lengths measured using digital calipers...

BACKGROUND: Procedure volume is an important determinant of total knee arthroplasty (TKA) outcomes. We aimed to determine whether computer navigation or patient-specific instrumentation (PSI) would improve postoperative alignment in a low-volume setting. HYPOTHESIS: PSI for TKA achieves better leg and implant alignment compared to conventional TKA and to computer navigated TKA. MATERIALS AND METHODS: This is a retrospective cohort study of 385 primary TKAs (Women = 59%...

INTRODUCTION: Implanting a knee prosthesis in patients aged over 85 years is not without risk. Unicompartmental knee arthroplasty (UKA) is reputed to show lower morbidity and mortality than total knee arthroplasty (TKA). Elderly patients with isolated unicompartmental osteoarthritis without specific contraindications are thus good candidates for this procedure. The present retrospective case-control study compared complications rates in elderly patients receiving UKA versus TKA. The study hypothesis was that UKA incurs fewer complications, with equivalent functional results...

INTRODUCTION: The rotational position of the femoral component is a primary driver of success in total knee arthroplasty. However, distal femoral torsion (DFT) varies greatly between individuals. Measuring DFT preoperatively by CT in combination with computer-assisted surgery can significantly improve the rotational positioning of the femoral component. However, a preoperative CT scan is costly and exposes the patient to radiation. These are doubled when the patient is undergoing bilateral arthroplasty...

INTRODUCTION: The humerus is the second most common long bone site of metastatic disease from renal cell carcinomas (RCC) after femur. Surgery has an important role in the treatment of these lesions due to renal cell tumor's resistance to chemotherapy and radiotherapy. HYPOTHESIS: Prosthetic replacement is an effective and safe solution in treatment of renal humeral metastasis. MATERIAL AND METHODS: 56 patients affected by RCC bone metastases of the humerus that underwent a surgical reconstruction were rewised...

BACKGROUND: No-go designates a decision not to perform surgery when it becomes apparent that safety and/or feasibility requirements are not met. No-go decisions can occur at any time between patient admission to a hospital department and immediately before the first incision. The primary objective of this study was to assess the causes of no-go decisions reported as healthcare-associated adverse events (HAAEs). HYPOTHESIS: Most no-go decisions in orthopaedic surgery are related to problems with medical devices...

INTRODUCTION: The glenoid track concept was used to confirm the engaging Hill-Sachs lesion (HSL) as a risk factor for recurrent instability following arthroscopic Bankart repair (ABR). However, the post-operative condition of soft tissue in vivo was not comparable to that designed in the intact condition in vitro in the original study of the glenoid track concept. Herein, the possibility of engagement may be underestimated. HYPOTHESIS: A threshold of the Hill-Sachs interval to glenoid track width ratio (H/G ratio) that is related to recurrent instability after ABR could be found, in order to adjust the original glenoid track concept...

INTRODUCTION: Fixed flexion and external rotation contractures are common in patients with hip osteoarthritis and in particular before total hip replacement (THR). We aimed to answer the following question: how does combined flexion and external rotation of the femur influence the radiographic assessment of 1) femoral offset (FO) 2) neck-shaft angle (NSA) and 3) distance (parallel to the femoral axis) from greater trochanter to femoral head centre (GT-FHC)? HYPOTHESIS: Combined flexion and external rotation impact the accuracy of two-dimensional (2D) proximal femur measurements...

In complex fractures of the proximal tibial metaphysis and epiphysis, possible adverse outcomes after internal fixation include not only joint surface incongruity, but also lower limb malalignment requiring revision surgery. Navigation has been proven effective for the intra-operative control of lower limb alignment during osteotomy and knee arthroplasty. In complex traumatic fractures, temporary fixation by a locking screw plate allows sensor positioning followed by navigation manoeuvres to adjust lower limb alignment...

BACKGROUND: A medial meniscus posterior root tear (MMPRT) is defined as an injury to the posterior meniscal insertion on the tibia. In MMPRT, the medial meniscus (MM) hoop function is damaged, and the MM undergoes a medial extrusion into the interior from the superior articular surface of the tibia. However, the details of MM position and movement during knee joint movement are unclear in MMPRT cases. The present study aims to evaluate MM position and movement via magnetic resonance imaging (MRI) examination of the MM posterior extrusion (MMPE) at knee flexion angles of 10° and 90°...
