Is pre-operative block-test with lidocaine injection efficient in predicting the functional result of revision total hip arthroplasty?

Background: While performing a hip joint aspiration for culture, a lidocaine diagnostic injection called block test can be performed during the investigation of painful total hip arthroplasties (THA). This test was formerly applied to limited series in pre-operative and without assessing the predictive value on the results of THA revision. Therefore we investigated a consecutive series of THA revisions who underwent pre-operative aspiration-block test to determine if patients with pre-operative positive block test (disappearance of symptoms) have a better clinical improvement after revision.

Comparison of classical and minimally invasive superolateral approach for reconstruction of proximal humerus fractures with locking plates.

Context: Minimally invasive (MI) approaches are purported to present advantages for osteosynthesis when compared with conventional approaches. This study aimed to compare the medium-term clinical and radiological outcomes of patients with proximal humerus fractures treated by plate osteosynthesis with conventional and MI superolateral approaches.

Method: The study carried out was a retrospective monocentric comparative analysis.

Poor clinical outcomes and high rates of dislocation after modular reverse shoulder arthroplasty for proximal humeral oncologic resection.

Purpose: The shoulder is the most common site for upper extremity tumors. The aim of the study was to analyze the outcomes and the complications of modular reverse shoulder arthroplasty (RSA) after proximal humerus resection.

Methods: We retrospectively included 15 consecutive patients who underwent a modular MUTARS™ RSA reconstruction after proximal humerus tumour resection between 2017 and 2020.

Limb schwannoma: Factors for postoperative neurologic deficit and poor functional results.

Introduction: Neurologic complications after limb schwannoma resection are not unusual, but there is no consensus on risk factors for neurologic deficit or poor functional results. We therefore conducted a retrospective study, to screen for factors predicting, firstly, postoperative neurologic deficit and, secondly, poor functional results.

Hypothesis: Certain pre- and intraoperative features predict risk of failure, poor results or aggravation.

Accuracy of the GeneXpert® MRSA/SA SSTI test to diagnose methicillin-resistant Staphylococcus spp. infection in bone fixation and fusion and management of infected non-unions.

Introduction: The GeneXpert® MRSA/SA SSTI (Methicillin Resistant Staphylococcus aureus/S. aureus skin and soft tissue infection) PCR test allows early detection of methicillin resistance in staphylococci. This test was developed for skin infections and has been evaluated for prosthetic joint infections but, to our knowledge, has not been evaluated for hardware infections outside of arthroplasties.

Improved nationwide survival of sarcoma patients with a network of reference centers.

Background: We investigated the impact of the implementation of a network of reference centers for sarcomas (NETSARC) on the care and survival of sarcoma patients in France since 2010.

Patients And Methods: NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized multidisciplinary tumor boards (MDTBs), funded by the French National Cancer Institute (INCa) since 2010.

Return to sport after surgery for osteochondral lesions of the talar dome. Results of a multicenter prospective study on 58 patients.

Introduction: Osteochondral lesions of the talar dome (OLTD) are most often found in patients for whom the return to sports activities is the main issue. Two types of surgery have been distinguished at present, bone marrow stimulation techniques and mosaicplasty techniques. The size of the lesion indicating the need for bone marrow stimulation as the required surgical procedure has recently been decreased (<1cm).

Recovery of leg strength based on isokinetic testing after tumor resection and reconstruction with a modular rotating hinge knee system: Prospective cross-sectional study with a minimum follow-up of 24 months.

Background: While modular reconstruction implants can be used to replace the bone lost after bone tumor resection, tumor excision from the neighboring soft tissues can lead to loss of strength and joint range of motion (ROM), which results in worse knee function. Functional recovery after total knee arthroplasty for osteoarthritis has been extensively documented. But few studies have evaluated the recovery after total knee reconstruction following tumor excision despite the fact that most of these patients are young and have high functional demands.

Higher preoperative range of motion is predictive of good mid-term results in the surgical management of osteochondral lesions of the talus: a prospective multicentric study.

Introduction: Osteochondral lesions of the talus (OLT) are a frequent cause of pain in young patients and a new CT arthrographic classification system of OLT was recently proposed to help guide the choices of and standardize the indications for surgical treatment. The primary hypothesis was that this algorithm would result in a postoperative AOFAS score of ≥ 80/100. The secondary hypothesis was to identify the preoperative factors of successful surgery.

Safety of malleolar osteotomies in surgery for osteochondral lesions of the talus.

Unlabelled: The talus is a central bone in the hindfoot that is difficult to access surgically. Performing a medial or lateral malleolar osteotomy in the management of an osteochondral lesion of the talus (OLT) is a feared procedure amongst surgeons and their patients. The objective of this study was to assess the complications inherent to malleolar osteotomies in the treatment of OLTs.

Osteochondral lesion of the talus: What are we talking about?

Introduction: The analysis of osteochondral lesions of talus (OLT) is currently mostly descriptive, not permitting an understanding of the different nosological frameworks of these lesions. Better knowledge of the characteristics of patients with OLT should make it possible to optimize the surgical indications and anticipate the associated lesions, which should not be overlooked. The main objective of this study was, therefore, to assess the characteristics of patients with OLT, and to analyze the lesions encountered.

Management of symptomatic postoperative epidural hematoma in spine surgery: Medicolegal implications.

Introduction: Spine surgery is one of the specialties with the highest medicolegal risk, with a legal action initiated every 17 months per practitioner. One of the most dreaded complications is an epidural hematoma with postoperative deficit. The treatment of this complication is still being debated.

Perilunate fracture-dislocations: Clinical and functional outcomes at a mean follow-up of 3.3 years.

Introduction: Perilunate lesions in the carpus are severe injuries whose functional consequences can limit patients' ability to regain their pre-injury activity levels. The aim of this study was to evaluate the outcomes of a series of patients who suffered a perilunate fracture-dislocation and to assess their ability to resume their social and professional activities.

Hypothesis: After surgical management of this injury, the medium-term functional outcomes will allow patients to return to their pre-injury social and professional activities.

A low teres minor index of trophicity negatively impacts the functional outcomes of reverse shoulder arthroplasty.

Introduction: The teres minor (TM) participates in active external rotation (ER) after reverse shoulder arthroplasty (RSA). The TM index of trophicity (T2/G) measured on CT scan is a predictor of poor results in patients who have irreparable rotator cuff tears. The aim of this study was to evaluate how T2/G impacts the functional outcomes of RSA in the context of massive rotator cuff tears.

Proposal of a new CT arthrographic classification system of osteochondral lesions of the talus.

Background: Surgical treatment of osteochondral lesions of the talus (OLT) is warranted if medical treatments fail, achieving good results in around 85% of cases. Numerous classification systems, based on all possible imaging modalities (radiography, MRI, CT scan, scintigraphy, and CT arthrography), have been proposed to guide surgical treatments, but none has proven to be superior. A recent study demonstrated the prognostic value of CT arthrography by accurately describing the subchondral bone plate.

Four-corner fusion: Clinical and radiological outcome after fixation by headless compression screws or dorsal locking plate at minimum 5 years' follow-up.

Introduction: Among the various procedures for degenerative carpal lesions, four-corner fusion relieves pain while conserving motion and strength. There are various fixation options, not presently standardised.

Hypothesis: Internal fixation by screws or dorsal locking plate provides good 5-year clinical results in four-corner fusion.

Arthroscopic Bankart Repair Versus Immobilization for First Episode of Anterior Shoulder Dislocation Before the Age of 25: A Randomized Controlled Trial.

Background: The risk of recurrence after the first episode of anterior shoulder dislocation is high with nonoperative treatment in younger patients.

Purpose/hypothesis: The aim of this study was to compare the results of arthroscopic Bankart repair and nonoperative treatment for shoulder dislocation in patients younger than 25 years, with a minimum of 2 years of follow-up. The hypothesis was that surgery would decrease the risk of recurrence.

Objective: This article describes the percutaneous technique of a minimally invasive basal closing wedge osteotomy for correction of hallux valgus.

Indications: This procedure allows correction of severe deformity with a minimally invasive approach.

Contraindications: No specific contraindication; a fusion would be preferred for an arthritic tarsometatarsal or metatarsophalangeal joint.

Long-term radiological changes and functional outcomes after proximal row carpectomy: Retrospective study with 3 years' minimum follow-up.

Introduction: The aim of this study was to analyze the radiological changes and determine the clinical and functional outcomes of proximal row carpectomy (PRC) over the long term.

Hypothesis: Radiological changes after PRC occur in every patient while the clinical and functional outcomes remain stable over time.

Methods: This was a retrospective single-center study of patients who underwent PRC between January 2004 and December 2014.

Clinical, functional and prognostic results after repair of peripheral lesions of the triangular fibrocartilage complex: a retrospective study of 21 patients.

Objectives: The main objective of this study was to assess the clinical and functional outcomes of arthroscopic TFCC repair in patients with an isolated Atzei type 1, 2 or 3 lesion or after a distal radius fracture. The secondary objective was to identify which factors could contribute to poor functional outcome.

Methods: A retrospective study was conducted from November 2017 to May 2019.

Total trapeziectomy for osteoarthritis of the trapeziometacarpal joint: Clinical and radiological outcomes in 21 cases with minimum 10-year follow-up.

Introduction: Trapeziectomy is a technique of choice for osteoarthritis of the trapeziometacarpal joint, but few studies have assessed long-term radiological and clinical outcome in total trapeziectomy, mean follow-up being rather between 2 and 6 years in most cases. The main aim of the present study was to assess loss of trapezial space height at a minimum 10 years' follow-up. Secondary endpoints comprised functional outcome at the same follow-up.
