Does the use of topical vancomycin during primary hip or knee arthroplasty protect from infections?

Background: Infection is one of the main complications of hip and knee arthroplasties. Topical application vancomycin to prevent postoperative infections is efficient in spine surgery, and is spreading in prosthetic surgery. However, its clinical relevance and safety are still under debate.

Assessment of the impact of telehealth intervention in patients with bone and joint infection.

Objectives: Patients with bone and joint infections (BJI) are involved in a complex care pathway and require prolonged antimicrobial treatment. Some studies have suggested that a pharmacist-led telehealth intervention (TI) could help to ensure better follow-up of chronic diseases. To our knowledge, there are no data on the effects of pharmacist-led TI on patients with BJI.

Bone-anchored prostheses for lower limb amputation in a French cohort with 1-15 years of follow-up: implant survival rates, mechanical complications, and reported outcomes.

Purpose: To evaluate the implant survival rate, mechanical complications, and reported patient outcomes of bone-anchored prostheses for patients with lower limb amputation in France after 1-15 years of follow-up.

Methods: This retrospective cohort study included patients who underwent surgery at a single center in France between 2007 and 2021. The primary outcomes were the implant survival rate and functional scores assessed by the Questionnaire for Transfemoral Amputees (Q-TFA).

Arthroscopic treatment of diffuse pigmented villonodular synovitis of the elbow.

Introduction: Pigmented villonodular synovitis (PVNS) is a rare pathology of the elbow, but presents a risk of progression with cartilage destruction. Surgical treatment consists in synovectomy, as complete as possible. Arthroscopy is an excellent tool for the exploration and treatment of intra-articular lesions in the elbow, but the results in PVNS of the elbow have never been evaluated.

Tibial pilon fractures treated with a periarticular external fixator: Retrospective study of 47 cases.

Introduction: Tibial pilon fractures are a treatment challenge, since there is no true gold standard treatment, and because of potential skin complications. Periarticular external fixation (PAEF) appears to produce good results, but the outcomes with the TL-HEX Trauma™ (Orthofix®, Verona, Italy) have not yet been evaluated. We performed a study with the following objectives: 1) evaluate time to union and union rate; 2) determine clinical and radiological results; 3) detect complications.

Post-traumatic forearm bone defect reconstruction using the induced membrane technique.

Introduction: The induced membrane technique, first described by Masquelet, is now well standardized, but little studied in post-traumatic forearm bone defect. The main aim of the present study was to analyze consolidation rates in this indication. The study hypothesis was that the induced membrane technique provides good consolidation results.

Management of Chronic Osteomyelitis by an Orthoplastic Team: 7-Year Experience of a University Hospital.

Background: Treating chronic osteomyelitis of the lower extremities is challenging. The treatment of acute lower limb trauma by orthoplastic teams has shown good results over the past few decades. This study aimed to characterize surgical outcomes of leg and heel chronic osteomyelitis by an orthoplastic team.

Learning and optimizing arthroscopic knot-tying by surgery residents using procedural simulation.

Introduction: Procedural training of orthopedic surgery residents includes learning arthroscopic knot-tying. The models used comprise arthroscopy training modules of increasing complexity, although there is no procedural training guide for the acquisition of arthroscopic knot-tying skills. Few studies have focused on how residents learn arthroscopic knot-tying.

Combining load sensor and robotic technologies for ligament balance in total knee arthroplasty.

Good ligament balance in total knee arthroplasty (TKA) is thought to improve clinical results, but is highly surgeon-dependent when performed without technological assistance. We therefore describe a TKA technique using the Mako robotic arm (Stryker, Kalamazoo, Michigan, USA) as sole means of balancing ligament tension by bone recuts associated to control by the VERASENSE load sensor (Orthosensor, Inc, Dania Beach, Florida, USA). In this preliminary series of 29 patients, 27 (93%) showed a well-balanced knee in extension at end of procedure, and 23 (79%) showed a well-balanced knee in flexion and extension, without any periarticular soft-tissue release.

Medium-term evaluation of leg lengthening by ISKD® intramedullary nail in 28 patients: Should we still use this lengthening system?

Introduction: Lower-limb lengthening presently uses intramedullary nailing. There are motorized systems and mechanical systems, each with their specific complications. The aim of the present study was to assess the efficacy of ISKD® mechanical nails (Orthofix Inc.

Surgical management of proximal femoral metastasis: Fixation or hip replacement? A 309 case series.

Introduction: The proximal femur is the most frequent operative site for metastasis, but there is no consensus between internal fixation and hip replacement. The present multicenter retrospective observational study sought: (1) to compare early clinical results between internal fixation and hip replacement for proximal femoral metastasis (PFM), and (2) to assess events affecting survival.

Hypothesis: The study hypothesis was that internal fixation and hip replacement give comparable clinical results, operative site complications rates and survival.

Surgical treatment of peri-acetabular metastatic disease: Retrospective, multicentre study of 91 THA cases.

Introduction: The occurrence of peri-acetabular metastasis (PAM) is a turning point in the progression of cancer because the disabling pain prevents the patient from walking or makes it difficult. Recent progress in controlling cancers that spread to the bone and controlling local bone destruction justify this national study. Since the data in France is incomplete or based on small studies, we analysed a multicentre retrospective cohort of patients with PAM who underwent total hip arthroplasty (THA) to evaluate 1) the clinical and radiological outcomes and 2) the factors impacting patient survival.

ACL reconstruction with lateral extra-articular tenodesis using a continuous graft: 10-year outcomes of 50 cases.

Background: Persistence of pivot shift is the main problem after isolated intra-articular anterior cruciate ligament (ACL) reconstruction. Adding lateral extra-articular tenodesis (LET) to the ACL procedure increases the knee's stability by controlling rotational laxity. The aim of this study was to evaluate the long-term clinical and radiological outcomes of combined ACL reconstruction with LET using a continuous hamstring graft as a first-line procedure.

Surgical treatment of tibial metastases: Retrospective, multicenter, observational study of 25 patients.

Introduction: Long bone metastasis to the tibia is somewhat rare and has only been studied in a few publications with a limited number of cases. This led us to carry out a large multicenter, observational, retrospective study to 1) evaluate the clinical and radiological outcomes of surgical treatment at this location and 2) highlight the specific risks associated with this condition.

Hypothesis: We hypothesized that the clinical outcomes and survivorship were comparable to those reported in the literature.

Three-dimensional computed tomography analysis and functional results of calcaneal fractures treated by an intramedullary nail.

Background: Intramedullary calcaneal nailing is used to treat displaced intra-articular calcaneal fractures. The main goal of the study was to assess the reduction of tomography and secondary goals were patient functional scores and complication rates.

Methods: The functional outcome and restoration of the radiographic parameters were evaluated post-operatively, at three months, at one year, and at the last follow-up.

Beach tennis injuries: a cross-sectional survey of 206 elite and recreational players.

: Although a million people regularly play beach tennis (BT) through the world there is no published information on BT injuries. The aim of this study was to describe the epidemiology of BT injuries, and to identify differences between injured and non-injured players.: This was a retrospective cross-sectional epidemiology study of 206 BT players from Réunion Island describing the injuries occurring in BT.

Coexistence of schwannomatosis and glioblastoma in two families.

Schwannomatosis is a rare affection predisposing to multiple peripheral neurologic tumors development. Approximatively, one third of patients with schwannomatosis are carriers of a germline mutation in LZTR1 (Leucin Zipper Transcription Regulator 1). Tumorigenesis in schwannomatosis responds to a somatic 5-hit/3-step mechanism resulting in a loss of function (LOF) of LZTR1 and the contiguous genes of locus 22q11.

Chromium-Cobalt Intoxication with Intense Systemic Complications following Total Hip Revision after Per-Operative Ceramic Fracture.

Introduction: Heavy metal intoxication after arthroplasty is extremely rare but could be lethal. We report the case of a 69-year-old woman, who presented intense systemic symptoms of chromium-cobalt intoxication after revision of per-operative fractured ceramic components with metal-on-polyethylene. Systemic toxicity occurred a year after surgery and expressed brutally with mostly central neurological symptoms.

Leg length discrepancy after total hip arthroplasty: Can leg length be satisfactorily controlled via anterior approach without a traction table? Evaluation in 56 patients with EOS 3D.

Background: Leg length discrepancy (LLD) occurs in about 25% of cases after total hip arthroplasty (THA) and adversely affects function if greater than 10mm. When using the direct anterior approach (DAA), limb length control is considered easier with a standard operating table than with a traction table. However, this assumption has not been confirmed.

Contribution of a multiplex serological test for the preoperative diagnosis of prosthetic joint infection: a prospective study.

Background: Prosthetic joint infection (PJI) is a severe complication of orthopaedic surgery. Preoperative diagnosis, although sometimes difficult, is key to choose the relevant treatment.

Methods: We conducted a prospective study aimed at evaluating the diagnostic performance of a multiplex serological test for the pre-operative diagnosis of PJI.

Percutaneous low-pressure bone stenting to control cement deposition in extensive lytic lesions.

Objective: To evaluate low-pressure bone stenting combined with cementoplasty in extensive lytic lesions.

Methods: A single-centre study involving four consecutive patients (four women) with extensive lytic tumours was performed. The average age was 65 years.

[Reticular perineurioma of the tibial nerve].

Reticular (retiform) perineurioma is a rare variant of soft tissue perineurioma developed from the perineurium. This benign tumor is characterized by strands of spindle cells in a fibro-myxoid matrix surrounding pseudocystic mucoid spaces. We report a tibial nerve reticular perineurioma in a 35-year-old patient.

[Sciatic nerve intraneural perineurioma].

Intraneural perineurioma is a benign tumor developed from the perineurium and responsible for localized nerve hypertrophy. This uncommon tumor is characterized by a proliferation of perineural cells with a "pseudo-onion bulb" pattern. We report a sciatic nerve intraneural perineurioma in a 39-year-old patient.
