Modified Distalization Shoulder Angle and Lateralization Shoulder Angle show weakly correlation with clinical outcomes following reverse shoulder arthroplasty.

Introduction: The focus in reverse shoulder arthroplasty (RSA) has been on the lateralization and distalization of prosthesis positioning, influenced by implant design and surgical technique. There's no consensus on the optimal amount of lateralization and distalization or the best radiographic parameters for evaluating placement. This study examines the correlation and the predictive value between previously described modified distalization shoulder angle (DSA) and lateralization shoulder angle (LSA) with postoperative outcomes, which aim to differentiate the contributions of the humeral and glenoid components in the global distalization and lateralization of the RSA.

Anterior Cruciate Ligament Reconstruction in Patients Older Than 50 Years: A Descriptive Study With Minimum 10-Year Follow-up.

Background: Anterior cruciate ligament (ACL) reconstruction is increasingly being performed in patients >50 years old; however, the long-term outcomes are unclear.

Purpose: To analyze the functional results, osteoarthritic progression, reoperation rate, and failure rate at minimum 10-year follow-up in patients >50 years old who have undergone primary ACL reconstruction.

Study Design: Case series; Level of evidence, 4.

Revision shoulder arthroplasty and proximal humeral bone loss: a comprehensive review and proposal of a new algorithm of management.

With the rising prevalence of shoulder arthroplasty, the incidence of revision shoulder arthroplasty is also increasing. The complexity of these revision procedures poses significant challenges, with bone loss being a critical factor impacting treatment outcomes. Addressing substantial humeral bone defects is crucial for ensuring implant stability and functionality.

Bone Density Changes at the Origin of the Deltoid Muscle following Reverse Shoulder Arthroplasty.

Reverse total shoulder arthroplasty (RSA) significantly impacts deltoid length, tension, and structure. Studies have extensively investigated various modifications in deltoid characteristics, such as perfusion, elasticity, caliber, histological changes, and strength post-RSA. However, to date, there is a notable absence of research evaluating changes in bone mineral density (BMD) at the deltoid muscle origin after the RSA procedure.

Osteotomies for genu varum: Should we always correct at the tibia? A multicenter analysis of practices in France.

Introduction: Tibial correction is often performed during a valgus-producing osteotomy for genu varum. However, overcorrection and the creation of a joint line obliquity (JLO) have been associated with unfavorable functional outcomes after high tibial osteotomy (HTO). The aims of this study were to analyze: 1) the corrections obtained after HTO; 2) the rationale behind the indication per the European Society for Sports Traumatology Surgery and Arthroscopy (ESSKA) recommendations; and 3) the correlation between the postoperative corrections obtained and functional outcomes.

Minimally invasive sacroiliac joint fusion secondary to lumbosacral fusion: Clinical and functional results at 2years of follow-up.

Introduction: Degenerative sacroiliac (SI) joint syndrome is known to be more common after lumbosacral fusion. While this diagnosis is suspected based on various clinical criteria and diagnostic tests, it is confirmed with a diagnostic nerve block. If conservative treatment fails, SI joint fusion through a minimally invasive approach is a useful palliative approach for patients at a treatment crossroads.

Validation of the shoulder range of motion software for measurement of shoulder ranges of motion in consultation: coupling a red/green/blue-depth video camera to artificial intelligence.

Purpose: Clinical evaluation of the shoulder range of motion (RoM) may vary significantly depending on the surgeon. We aim to validate an automatic shoulder RoM measurement system associating image acquisition by an RGB-D (red/green/blue-depth) video camera to an artificial intelligence (AI) algorithm.

Methods: Thirty healthy volunteers were included.

Open palmar metacarpophalangeal joint dislocation: Case report, pathogenesis and literature review.

We report the case of a 58-year-old man who sustained an open palmar dislocation of the fifth metacarpophalangeal joint of the little finger secondary to a bicycle accident with an uncommon presentation. These open dislocations have only been reported once in the literature. A palmar and dorsal approach had to be used to completely free the joint from incarcerations and allow complete reduction and repair of the damaged anatomical structures.

Can surgeons optimize range of motion and reduce scapulohumeral impingements in reverse shoulder arthroplasty? A computational study.

Background: Early glenohumeral impingement leads to poor range of motion and notching in reverse shoulder arthroplasty. The aim was to find from planning software which implant configuration provides the best motions in reverse shoulder arthroplasty.

Patients And Methods: Reverse shoulder arthroplasty planning (Glenosys) was made in 31 patients (12 men, 19 women, 76 ± 6 yo) and impingements were analyzed.

Comparative study of bilateral total hip arthroplasty in one or two stages.

Introduction: Bilateral total hip arthroplasty (Bi THA) for disabling bilateral hip osteoarthritis can be performed in one or two operative sessions. The objective of this study was to compare the complication rates of a group of patients who had bilateral THA in one operating session (Bi-1S THA) to a matched group of patients who had bilateral THA in two separate operating sessions (Bi-2S THA).

Materials And Methods: This retrospective case-control study compared 84 Bi-1S THA matched to 84 Bi-2S THA by age, gender, diagnosis, ASA score (1-2) and surgical approach.

Patient-specific guides in orthopedic surgery.

The interest of patient-specific guides (PSGs) lies in reliable intraoperative achievement of preoperative planning goals. They are a form of instrumentation optimizing intraoperative precision and thus improving the safety and reproducibility of surgical procedures. Clinical superiority, however, has not been demonstrated.

The impact of confinement on orthopaedic and trauma surgical activity.

Introduction: On the 16th of March 2020, in the face of a health emergency declared in France, the government imposed containment measures whose impact on orthopaedic and trauma surgery remains to be demonstrated. The hypothesis of this study was that confinement reduced orthopaedic and trauma surgical activity. The main objective was to assess orthopaedic and trauma surgical activity during confinement and to compare it to the activity outside confinement.

High tibial flexion osteotomy for symptomatic ligamentous genu recurvatum.

Introduction: Symptomatic Ligamentous Genu Recurvatum (SLGR) is characterized by an asymmetrical hyperextension of the knee associated with pain and a feeling of instability occurring even during walking. The ligamentous origin of the recurvatum is linked to a sprain in hyperextension responsible for a rupture of the posterior structures that may be associated or not with a rupture of the cruciate ligaments.

Hypothesis: Tibial Flexion Osteotomy (TFO) allows control of a SLGR without rupture of the cruciate ligaments secondary to a sprain in hyperextension.

Short-term outcomes and survival of pyrocarbon hemiarthroplasty in the young arthritic shoulder.

Hypothesis: The purpose was to report the short-term outcomes and survival of hemiarthroplasty with a pyrocarbon head (HA-PYC) for the treatment of shoulder osteoarthritis in patients aged ≤ 60 years. We hypothesized that HA-PYC could be an alternative to hemi-metal (avoiding the risk of rapid glenoid erosion) and total shoulder arthroplasty (TSA) (avoiding the risk of rapid glenoid loosening) in an active patient population.

Methods: Sixty-four consecutive patients (mean age, 53 years) who underwent HA-PYC for glenohumeral osteoarthritis were included.

Outpatient shoulder prostheses: Feasibility, acceptance and safety.

Introduction: Outpatient surgery in France is defined by the national authority for health (HAS) as a scheduled surgery enabling same-day discharge without any increased risk to the patient. With the advent of enhanced recovery after surgery, outpatient lower limb arthroplasty has become a common procedure. However, only 1.

Arterial grafts for proper palmar digital artery reconstruction: An anatomical study.

Digital ischemia due to arterial defects need urgent surgical management. The traditional treatment consists of vascular reconstruction using a reversed autologous venous graft as a bypass. Very few studies have described the use of arterial grafts for digital artery reconstruction.

Volar fracture dislocation of the 2nd metacarpal base associated with acute carpal tunnel syndrome: A case report.

Posttraumatic acute carpal tunnel syndrome is a not a usual complication in traumatic hand injuries but requires more urgent and aggressive management. Compression of the median nerve should be systematically sought when there is a major and painful swelling of the hand, associated with one or several hand and wrist fractures. In rare case, a single metacarpal fracture or dislocation can be the only cause of median nerve compression and requires urgent diagnosis.

One-stage bilateral total hip arthroplasty versus unilateral total hip arthroplasty: A retrospective case-matched study.

Background: One-stage bilateral hip replacement has the advantage of involving a single anesthesia, single hospital admission and single rehabilitation program. The theoretic drawback is increased surgical risk. Few French series have been reported, and none with comparison versus unilateral arthroplasty.
