BACKGROUND: Pelvic incidence (PI) is an anatomical parameter that is considered invariable in a given individual. Although changes in posture influence the mobile lumbar spine, lumbar lordosis (LL) and the pelvis are typically evaluated only in the standing position. Thus, whether other positions commonly used during daily activities influence the relationship between LL and PI is unknown. The objective of this study was to determine whether LL and sacral slope (SS) correlated with PI, using two standardised positions, seated and supine), different from the standing position that is generally used...

Patellar complications are a source of poor total knee arthroplasty (TKA) outcomes that can require re-operation or prosthetic revision. Complications can occur with or without patellar resurfacing. The objective of this work is to answer six questions. (1) Have risk factors been identified, and can they help to prevent patellar complications? Patellar complications are associated with valgus, obesity, lateral retinacular release, and a thin patella. Selecting a prosthetic trochlea that will ensure proper patellar tracking is important...

The recent development of high-frequency ultrasonography transducers has provided better accuracy and improved the ability to image more superficial body structures. Ultrasonography is a widely available, inexpensive, comparative, and dynamic imaging technique that involves no radiation exposure and has no other adverse effects. Ultrasonography must always be combined with a medical history, physical examination, and radiographic assessment. What is ultrasound-assisted orthopaedic surgery? This approach consists in the use of ultrasonography by orthopaedic surgeons during patient visits and/or in the operating room...

INTRODUCTION: The indications for surgical treatment of displaced proximal humerus fractures in older patients have gradually changed in the past 10 years: fewer hemiarthroplasty (HA) procedures but more reverse shoulder arthroplasty (RSA) procedures are being done. The aim of this study was to determine the clinical and radiological outcomes, the complications, reoperations and revisions of RSA and to compare them with those of HA. MATERIAL AND METHODS: A systematic review of the literature published between January 2006 and February 2016 was carried out to identify studies reporting or comparing results of HA and RSA for proximal humerus fractures in patients above 65 years of age...

HYPOTHESIS: Percutaneous pedicle screw fixations (PPSF) are increasingly used in spine surgery, minimizing morbidity through less muscle breakdown but at the cost of intraoperative fluoroscopic guidance that generates high radiation exposure. Few studies have been conducted to measure them accurately. MATERIAL AND METHODS: The objective of our study is to quantify, during a PPSF carried out in different experimented centers respecting current radiation protection recommendations, this irradiation at the level of the surgeon and the patient...

BACKGROUND: Fractures of the distal radius only rarely give rise to complications in the immediate post-operative period. Combined median and ulnar nerve palsy is a complication that can be missed by the surgeon. MATERIALS AND METHODS: Three cases diagnosed early after surgery are reported here. The patients were 15, 16, and 30 years of age, respectively. None had pre-operative neurological deficits. The youngest patient was injured during sports and the other 2 patients during traffic accidents...

INTRODUCTION: Arthroscopic remplissage of a Hill-Sachs lesion (HSL) associated with a Bankart repair (BR) has been recently introduced as a surgical option to treat chronic anterior shoulder instability. The purpose of this study was to analyze the current literature comparing results of isolated BR versus BR+remplissage in the treatment of anterior shoulder instability with engaging HSL. HYPOTHESIS: BR+remplissage are superior to isolated BR in the management of anterior shoulder instability with engaging HSL...

INTRODUCTION: Preserving constitutional patellofemoral anatomy, and thus producing physiological patellofemoral kinematics, could prevent patellofemoral complications and improve clinical outcomes after kinematically aligned TKA (KA TKA). Our study aims 1) to compare the native and prosthetic trochleae (planned or implanted), and 2) to estimate the safety of implanting a larger Persona® femoral component size matching the proximal lateral trochlea facet height (flange area) in order to reduce the native articular surfaces understuffing generated by the prosthetic KA trochlea...

Reconstruction of the proximal humerus after tumour resection is a surgical challenge. The goal consists not only in reconstructing the resected bone segment, but also in restoring a stable and mobile shoulder. The choice of the technique depends on the status of the soft tissues at the end of the resection. The pre-operative work-up must determine the oncological goals of the resection and identify the structures that can be spared. When deltoid muscle function is preserved, a reverse prosthesis offers the best stability and mobility outcomes...

BACKGROUND: Osteo-chondral defects due to advanced osteochondritis of the knee eventually cause osteoarthritis. Autologous matrix-induced chondrogenesis (AMIC) may hold potential for overcoming the treatment challenges raised by defects larger than 2 cm2 . The primary objective of this study was to assess medium-term functional outcomes of AMIC. The secondary objective was to confirm the absence of adverse events. HYPOTHESIS: AMIC significantly improves knee function in patients with osteochondritis responsible for osteo-chondral defects grade III or IV in the International Cartilage Repair Society (ICRS) classification...

BACKGROUND: This study aimed to evaluate the relationship between upper instrumented vertebra (UIV) level and cervical sagittal alignment (CSA) in Lenke 1 adolescent idiopathic scoliosis (AIS) patients, treated with posterior instrumentation. The hypothesis was that higher level of UIV would cause decreased cervical lordosis. METHODS: 63 Lenke 1 AIS patients that underwent posterior fusion with pedicle screw instrumentation were retrospectively evaluated. Patients were divided into three groups according to UIV level (T2, T3, T4)...

INTRODUCTION: Arthroscopic meniscectomy and medial meniscal repair are frequent procedures, liable to be complicated by iatrogenic cartilage lesions, especially in tight knee. Medial collateral ligament pie-crusting was developed to counter this, but, although the technique is employed, its impact on medial laxity has not been precisely determined. We therefore conducted a prospective observational study to compare radiographic laxity preoperatively versus 6 weeks following pie-crusting...

INTRODUCTION: The Scarf osteotomy is a commonly used surgical procedure for treating hallux valgus in Europe. Screw fixation is standard practice, although some surgeons now go without internal fixation. Plate fixation is still being studied. The aim of this study was to compare the radiological outcomes of these fixation methods, which has not been performed up to now. HYPOTHESIS: Relative to screw fixation, plate fixation of a Scarf osteotomy of the first metatarsal (M1) prevents secondary impaction, without increasing the complication rate or recurrence rate...

BACKGROUND: Infection is a common complication of major lower limb-sparing surgery with massive total knee prosthesis (MTKP) reconstruction after extensive tumour resection. When free tissue transfer is required to cover the prosthesis, musculo-cutaneous flaps are usually preferred based on proven efficacy when used in both one-stage and two-stage procedures. The use of a free fascio-cutaneous antero-lateral thigh (FC-ALT) flap in 3 patients with infected knee reconstructions is reported here...

STUDY HYPOTHESIS: We hypothesized that altered coronal balance in adolescent scoliosis leads to asymmetric stress on the lower limbs, with subsequent effects on bone maturation and later morphology. We aimed to assess the correlation between the biomechanical parameters of the lower limbs and coronal balance in idiopathic scoliosis. MATERIALS AND METHODS: In this study, EOS images of 280 patients and 56 controls were randomly selected from our clinics' database...

BACKGROUND: It is often difficult to achieve stable fixation in Tile type C1 pelvic fractures and there is no standard fixation technique for these types of injuries. HYPOTHESIS: Iliac screw fixation can be used for treating Type C1 pelvic fractures. PATIENTS AND METHODS: A retrospective review was performed on 47 patients who underwent iliac screw fixation in posterior column of ilium (PCI) for Tile type C1 pelvic fractures from July 2007 to December 2014...

INTRODUCTION: Surgery is indicated in De Quervain's tenosynovitis only after failure of medical treatment, often due to individual anatomical variants. We use Le Viet's technique, to avoid tendon instability. The aim of the present study was to evaluate long-term results, with the hypothesis that this surgical technique is reliable, providing lasting results. PATIENTS AND METHODS: All patients operated on between 1993 and 2015 were included, and results were assessed by telephone questionnaire at a minimum 1 year's follow-up...

INTRODUCTION: The TLS® technique for anterior cruciate ligament (ACL) reconstruction has the advantages of using only one hamstring tendon (semitendinosus) by preparing a short graft secured with screws and braided strips. The theoretical pitfall of this technique is that the graft length is determined arbitrarily. Thus, if the blind tunnels are not long enough, it will be impossible to tension the graft properly upon fixation. The primary objective of this study was to determine the postoperative side-to-side difference in knee laxity...

BACKGROUND: Adolescent idiopathic scoliosis (AIS) can require surgical procedures that have major consequences. Coronal imbalance as assessed clinically using a plumb line is a key criterion for selecting patients to surgery. Nevertheless, the reference standard for assessing postural balance of the trunk is gravity line localisation within a validated frame of reference. Recent studies have established that the gravity line can be localised after body contour reconstruction from biplanar radiographs...
