Despite satisfactory mid-term and long-term outcomes of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) procedures for thumb carpometacarpal osteoarthritis, there is limited literature describing detailed chronological changes in early-phase postoperative outcomes. We investigated chronological changes of subjective, objective, and radiological outcomes within 1 year post-trapeziectomy with LRTI using a longitudinal evaluation and analyzed clinical factors associated with patient-...
Operative therapy using a headless cannulated variable pitch compression screw is the gold standard for the treatment of instable scaphoid fractures.
Ultrasonography (US)-guided corticosteroid injection (CI) has been attempted to improve injection accuracy in de Quervain's disease (dQD), but its role in improving clinical outcomes and decreasing skin hypopigmentation or atrophy was not established well.
The volar locking plate (VLP) system provides stable fixation and is widely used for distal radius fractures. Studies have shown that irritation of the implant prominence is a risk factor for flexor tendon rupture, especially of the flexor pollicis longus (FPL). Contact between VLPs and flexor tendons should be avoided. We aimed to investigate the ulnar facet locking screw locations of various VLPs placed without FPL tendon contact in cadaver wrists.
The definite treatment of pelvic C fractures presents a widely discussed issue and undergoes continuous evolution. While the stabilization of the posterior ring has been studied extensively, the fixation of the anterior pelvic ring continuous to be rarely investigated. The importance of the simultaneous stabilization however lays in the earlier mobilization and prevention of long-term damage to the pelvis. Therefore we investigated four combinations of minimally invasive fixation techniques for unstable typ...
Despite tremendous advantages in the development and application of megaprostheses in tumour and revision surgery, complications are still not infrequently observed. Only two studies investigating the outcome of the LPS™ system in the proximal femur and distal femur/proximal tibia have been published thus far. Herein, mid-term implant survival rates one of the largest cohort of patients treated with the LPS™-system are presented aiming tp answer: 1) How is the outcome of the LPS™ system in the proxima...
Massive irreparable posterosuperior rotator cuff tears may result in a loss of external rotation. Most of these patients lose their ability to perform activities of daily living (ADLs), especially where external rotation and abduction are needed. Latissimus dorsi tendon transfer (LDTT) is a method to restore abduction and external rotation in patients with posterosuperior rotator cuff tears. There are no objective data concerning whether LDTT can restore range of motion (ROM), especially in performing ADLs ...
The pathogenesis of degenerative subscapularis (SC) tear is not clear, several mechanisms are involved: intrinsic tendon degeneration or subcoracoid impingement. The aim of this study was to propose new radiographic markers, the coraco-lesser tuberosity angle (CLA), lesser tuberosity angle (LTA) and lesser tuberosity height (LTH). The hypothesis was that higher values of CLA, LTA, and LTH would be associated with a higher likelihood in detecting a SC tear.
The aim for the present study was to determine whether projection error of measuring Pauwels' angle in young femur neck fracture could be eliminated by CT plane manipulation.
Tibial fractures are devastating injuries and a cause of significant morbidity. There is limited information describing the length of time it takes for these injuries to heal. The aim of this study was to define the normal distribution of healing times of a consecutive series of tibial fractures treated with intramedullary (IM) nailing by applying the Radiographic Union Scale for Tibial fractures (RUST).
Pure traumatic spinal cord injury (without associated bone lesion) are encountered in pediatric accidentology, the most typical being spinal cord injury without radiological abnormality (SCIWORA). The present study reports a multicenter series of under-18-year-olds admitted for traumatic medullary lesion. The objectives were: (1) to describe the causes of pure spinal cord injuries in children in France and their clinical presentation; (2) to identify any prognostic factors; and (3) to describe their medical...
Spinal fractures are rare in children, in whom they contribute only 2% to 5% of all traumatic spinal injuries. The management of burst fractures is well standardised in adults but remains controversial in paediatric patients, due to specific growth-related considerations. The objective of this study was to assess the clinical and radiographic outcomes of surgical management in a multicentre cohort of paediatric patients with burst fractures, in order to devise an optimal therapeutic strategy.
Intraoperative three-dimensional (3D) imaging is now feasible because of recent technological advances such as 3D cone-beam CT (CBCT) and flat-panel X-ray detectors (FPDs). These technologies reduce the radiation dose to the patient and surgical team. The aim of this study is to review the advantages of 3D intraoperative imaging in orthopedic and trauma surgery by answering the following 5 questions: What are its technical principles? CBCT with a FPD produces non-distorted digital images and frees up the su...
Restoring shoulder mobility, stability, and strength is a key goal in patients with brachial plexus injuries. Shoulder arthrodesis is chiefly used as an adjunct to, or after failure of, initial direct nerve surgery. The objective of this study was to compare clinical and functional shoulder outcomes after direct nerve transfer vs. shoulder arthrodesis in adults with supra-clavicular brachial plexus injuries.
Proximal femur fractures have significant functional repercussions in both older adults (sometimes life-threatening) and younger adults (socioeconomic). This study will review the early mechanical complications (EMC) associated with the fixation of femoral neck (FNF) and trochanteric (TF) fractures. What is the nature of these complications? They consist of incorrect fracture fixation, secondary displacement and/or fixation failure (FNF: 3-10%; TF: 5-7%), and more rarely, secondary fractures distal to the i...
Reverse shoulder arthroplasty (RSA) was introduced in 1985 by Grammont for patients with gleno-humeral osteoarthritis and severe rotator cuff damage. Internal rotation (IR) is limited in some patients after RSA. The objective of this study was to identify pre- and intra-operative factors associated with good IR outcomes 6 months after RSA.
The purpose of this study is to evaluate which factors will affect range of motion (ROM) and function in partial radial head fractures. The hypothesis is that conservative treatment yields better outcomes.
Hip replacement was declared "operation of the century" in tribute to the functional improvement it provides. Frequency is increasing, but it is difficult to estimate the actual number of procedures performed and the expected progression, because of changes in indications and lengthening life-expectancy, and also, in France, because there is no registry. As data are lacking in France, we conducted an investigation 1) to update the number of hip surgeries in France, and 2) to forecast progression over the co...
Previous research suggests that patient-reported outcomes plateau by one year after total knee replacement (TKR). Analysis of trajectories to date has predominately been based on changes in median/mean scores over the first post-operative year, rather than variability in trajectory patterns over the longer-term. The aim was to evaluate variability in long-term pain and function trajectories after TKR.
Internal impingement of the shoulder (IIS) is the leading cause of chronic shoulder pain in overhead throwing athletes. No consensus exists about which techniques are optimal when surgery is in order. The available studies are limited by small sample sizes and short follow-ups. The primary objective of this study was to assess return-to-sports (RtS) outcomes after surgical treatment for IIS. A favourable RtS outcome (RtS+) was defined as returning to the previous sport at the same or a higher level.
The tibiofibular syndesmosis is a fibrous joint essential for ankle stability, whence the classical comparison with a mortise. Syndesmosis lesions are quite frequent in ankle trauma. This is a key element in ankle stability and lesions may cause pain or instability and, in the longer term, osteoarthritis. The lesions are often overlooked due to diagnostic difficulties, but collision sport with strong contact is the main culprit. Diagnosis, whether in the acute or the chronic phase, is founded on an associat...
The primary symptoms of elbow osteoarthritis are the progressive development of stiffness along with pain at the end range of motion due to osteophyte impingement. Surgical treatment involves resecting these "bone stops". In the literature, these osteophytic lesions are more common than cartilage lesions, which suggests they may occur beforehand. The aim of our study was to confirm osteophytes are more common than cartilage lesions, and also to establish a link between these lesions and the functional outco...
Two-dimensional (2D) and three-dimensional (3D) computed tomography (CT) have been increasingly used in various intra-articular fractures including pilon fracture. However, no study has investigated intraobserver and interobserver reliabilities of pilon fracture classification using 3D CT images.
Musculoskeletal dysplasias (MSD) are inherited conditions of abnormal cartilage and bone development and remodeling which include, amongst others, multiple epiphyseal dysplasia (MED), spondyloepiphyseal dysplasia (SED), achondroplasia, and hypochondroplasia. The aim of this study was to compare patient characteristics and in-hospital complications between MSD and non-MSD patients undergoing total joint arthroplasty (TJA).
Posterosuperior (or internal) impingement at the shoulder is defined as contact between the underside of the supraspinatus or infraspinatus tendons with the posterosuperior labrum during extreme external rotation and abduction. In many cases, this contact damages the tendon and causes mirror posterosuperior labrum deterioration. The primary aim of this study was to define whether this contact occurs normally in patients who do not have a rotator cuff tear.
