MRI evaluation of ATFL and CFL ligamentization after anatomical surgical reconstruction with a hamstring graft.

Background: Chronic ankle instability is frequent complication following ankle sprains. Anatomical reconstruction of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) with a gracilis autograft is a validated reconstruction technique. The signal-to-noise quotient ankle (SNQA) score evaluates graft maturation with MRI and has been shown to be reproducible and reliable.

Adaptation of the Signal Noise Quotient MRI classification for graft ligamentization analysis following ATFL and CFL anatomical reconstruction: Validation of the SNQA.

Background: Chronic ankle instability is the most frequent clinical sign of an antero tibiofibular (ATFL) and/or calcaneo fibular ligament (CFL) tear. One common surgical technique is to use the distal tendon of the gracilis muscle to reconstruct both the ATFL and CFL. In the knee, the hamstring tendons used in anterior cruciate ligament (ACL) reconstruction may go through structural modifications called "ligamentization ".

Risk factors for passive anterior tibial subluxation on MRI in complete ACL tear.

Introduction: In anterior cruciate ligament (ACL) tear, passive spontaneous anterior tibial subluxation (ATS), with respect to the femur, is sometimes observed on MRI. In a case-control study, ATS>3.5mm showed 100% specificity (±3.

Autologous Conditioned Plasma for tendon healing following arthroscopic rotator cuff repair. Prospective comparative assessment with magnetic resonance arthrography at 6 months' follow-up.

Introduction: Despite improvements in technique and materials for rotator cuff repair, mean re-tear rates remain close to 30%. The aim of the present study was to assess injection of Autologous Conditioned Plasma (ACP™, Arthrex) for tendon healing after arthroscopic repair. The study hypothesis was that ACP™ improves the tendon-healing rate.

A threshold value of 3.5 mm of passive anterior tibial subluxation on MRI is highly specific for complete ACL tears.

Purpose: To identify and quantify passive anterior tibial subluxation on MRI using a standardized measurement protocol and determine the diagnostic threshold of subluxation for complete anterior cruciate ligament tears.

Methods: A retrospective case-control study was performed. Patients who underwent surgery for a complete isolated ACL tear between 2009 and 2015 were matched for age and gender to controls with an intact ligament on knee MRI.

Arthroscopic meniscal allograft transplantation with two tibia tunnels without bone plugs: evaluation of healing on MR arthrography and functional outcomes.

Introduction: Meniscal allograft transplantation seems to be a valid therapeutic option to restore the knee function and limit the development of osteoarthritis after menisectomy. No surgical technique has been shown to provide better results than others. The main objective of this study was to assess graft healing after arthroscopic meniscal allograft transplantation without bone plugs.

Reliability and validity assessment of a glenoid bone loss measurement using the Bernageau profile view in chronic anterior shoulder instability.

Background: One of the identified risk factors for anterior shoulder instability is bone loss on the anterior-inferior glenoid rim. The aim of our study was to assess intraobserver and interobserver reproducibility of the Bernageau view to estimate glenoid bone loss and validate this radiographic method with computed tomography (CT) scan. The second objective was to find correlation between Bernageau and arthroscopic bone loss measurements.

Residual inferior glenohumeral instability after arthroscopic Bankart repair: radiological evaluation and functional results.

Introduction: Treatment of anteroinferior shoulder instability by arthroscopy must restore stability while preserving joint motion. Inferior glenohumeral ligament (IGHL) laxity is an important parameter in the pathomechanism of this condition. The goals of this study is to use the Shoulder HyperAbduction Test (SHART) radiological test to quantify the tension in the IGHL following surgery and look for an eventual correlation between ligament tightening and joint motion.

[Hip degeneration].

Hip degeneration is typically easily diagnosed, based on the combination of clinical findings and plain films showing the four classifical findings: joint space narrowing, osteophytes, subchondral sclerosis and subchondral cysts. Some degenerated hips may have misleading features such as when joint space narrowing is mainly posterior or the main finding is a large subchondral cyst. Rapidly destructive coxopathy results in joint space narrowing and joint destruction over a few months.

Does arthroscopic rotator cuff repair actually heal? Anatomic evaluation with magnetic resonance arthrography at minimum 2 years follow-up.

Purpose: The goal of this series was to evaluate the clinical and anatomical outcomes of all-arthroscopic rotator cuff tears repair at a mid-term follow-up, using MR arthrography in order to assess tendon-to-bone healing.

Materials And Methods: This retrospective study included 29 patients (31 shoulders) presenting, according to Cofield classification, a small or moderate-sized supraspinatus full thickness tear with (7/31) or without (24/31) infraspinatus extension. The mean size of the tear was 2.

SHART: shoulder hyperabduction radiological test.

Purpose: To evaluate and quantify laxity of the inferior glenohumeral ligament (IGHL) in post-traumatic anterior instability of the shoulder with the shoulder hyperabduction radiological test (SHART) and correlate it with arthroscopic findings.

Methods: This prospective study included 21 patients undergoing arthroscopic stabilization for anteroinferior shoulder instability. The SHART test was performed as follows: a bilateral AP radiograph was performed in the supine position, and radiographs were compared.

CT and MRI of spine and sacroiliac involvement in spondyloarthropathy.

Objective: Spondyloarthropathies are rheumatoid diseases that predominantly affect the axial skeleton, causing pain, stiffness, and ankylosis. The aims of this article are to illustrate the different stages of the diseases from early inflammatory involvement to ankylosis using CT and MRI and to discuss the role of imaging in the management of affected patients.

Conclusion: CT and MRI are the most sensitive techniques in the detection of axial involvement, permitting earlier diagnosis and optimized treatment.

[Plain films of pelvis].

Plain films of the pelvis remain informative and allow most of the diagnoses. Assesment of the hip joint space, bone and subchondral structures, sacrum as well as sacroiliac joints is made on the AP view. Oblique views are useful.

[Double localization of an osteoid osteoma of the ankle: percutaneous treatment by CT-guided drilling].

A 26-year-old woman presented a rare double localization of an osteoid osteoma of the ankle. The first focus was situated in the tibial metaphysic, bordering the distal tibiofibular joint. The second focus was also superficial, located in the neck of the homolateral talus.

[Imaging of traumatic injuries of the elbow].

Traumatic injuries to the elbow may result in dislocations and/or fractures of the distal humerus or proximal radius or ulna. Multiple and associated lesions are common. Plain radiographs usually allow accurate diagnosis.

[Dynamic radiographic evaluation of the antero-inferior gleno-humeral ligament].

Purpose Of The Study: The purpose of this work was to propose an objective radiographic evaluation of the antero-inferior gleno-humeral ligament for comparison with the clinical assessment proposed by Gagey.

Material And Methods: A test radiogram was obtained from 32 healthy volunteers (15 men, 17 women, mean age, 29 years, age range 21-54 years) free of shoulder disease. The dynamic test image consisted in a strictly AP view of the shoulder in forced abduction in neutral rotation.
