The criteria for inclusion in this review were cases of COVID-19 infection subsequently developing heterotopic ossification.

Effects of Manual Therapy on Parkinson's Gait: A Systematic Review.

Manual therapy (MT) is commonly used in rehabilitation to deal with motor impairments in Parkinson's disease (PD). However, is MT an efficient method to improve gait in PD? To answer the question, a systematic review of clinical controlled trials was conducted. Estimates of effect sizes (reported as standard mean difference (SMD)) with their respective 95% confidence interval (95% CI) were reported for each outcome when sufficient data were available.

Qualitative and quantitative analysis of post-operative drainage: pilot study.

Surgical drains can be placed after an operation to collect postoperative blood loss. However, these could be overestimated. Indeed, the fluid elapsed after the first postoperative day would no longer be pure blood.

Methods: We conducted an observational retrospective monocentric study in a French physiotherapy school named "X.

[Ballistic concepts and management of gunshot wounds at members].

Ballistic trauma is not the prerogative of battlefields and currently extends to civil environments. Any surgeon or emergency room can be faced with such trauma whose management requires an understanding of wound ballistics. The aim of this retrospective is reviewing the management of ballistic trauma within the C.

Restoring lumbar spine stiffness using an interspinous implant in an ovine model of instability.

Background: The objective of this study was to determine the effect of an interspinous implant on lumbar spine stability and stiffness during dorsoventral loading.

Methods: Twelve Merino lambs were mechanically tested in vivo. Oscillatory (2 Hz) loads were applied to L2 under load control while displacements were monitored.

[Evolution of low back pain after bariatric surgery].

Although frequently called to mind by physicians, the relationship between overweight and low back pain is poorly understood and remains controversial. The present study aims to evaluate the evolution of low back pain in 65 patients planned for a bariatric surgery. The patients were enrolled prospectively.

[Treatment of osteoporotic fractures. A new approach by vertebroplasty and kyphoplasty].

Osteoporosis is a systemic disease and results in progressive bone mineral loss and concurrent change in bone architecture that leave bone vulnerable to fracture. In one third of patients with acute vertebral fracture, severe pain and limited mobility persist despite appropriate nonoperative management. Vertebroplasty is a minimally invasive method that involved the percutaneous injection of cement into a collapsed vertebral body to stabilize the fractured vertebra.

Bone morphogenetic protein 7 in the treatment of congenital pseudarthrosis of the tibia.

We describe a 13-year-old boy with atrophic tibial pseudarthrosis associated with neurofibromatosis who had undergone nine unsuccessful operations. Eventually, union was obtained by the use of bone morphogenetic protein 7 in conjunction with intramedullary stabilisation and autologous bone graft.

Analysis of the capital femoral line orientation. A CT scan study.

An accurate knowledge of the relationship between the neck and the epiphyseal plate at the end of growth is important for biomechanical investigations of femoral neck remodelling during childhood. Statistical data about the position of the epiphyseal femoral cartilage in relation to the neck axis at the end of the growth, are rare in the literature. As the trace of the epiphysis can be observed on a CT scan view of an adult hip, cadaver femurs were investigated to study this relationship and to avoid irradiation of children.

Anatomical and radiological correlation of Lequesne's "false profile".

Lequesne introduced a radiological projection, which is an oblique view of the edge of the acetabulum, to diagnose arthrosis affecting the anterior part of the joint and to measure the anterior coverage of the femoral head. In this study, we attempted to determine the anatomical correlation of his technique. Fifteen in vitro hemipelvises underwent radiography according to Lequesne's description, using metallic markers and wires to mark physical landmarks.

Theoretical study of the decrease in the femoral neck anteversion during growth.

This theoretical analysis tries to explain the decrease of the femoral neck anteversion during growth according to well-established concepts. In the frontal plane, it was demonstrated that the capital epiphyseal plate inclination allows the plate to remain perpendicular to the resultant force applied to the hip during gait. In the transversal plane, the projection of this force varies from -24 degrees, outwards and forwards (heel strike), to 20 degrees, outwards and backwards (toe off).

Traumatic hallux valgus following rupture of the medial collateral ligament of the first metatarsophalangeal joint: a case report.

Metatarsophalangealjoint injuries of the great toe are receiving increasing attention in athletes. Significant disability and long-term morbidity can result from these focal injuries. The entity known as turf-toe is widely recognized.

Localized pigmented villonodular synovitis of the knee with bone involvement mimicking a benign bone tumor: CT and MR findings.

The localized form of pigmented villonodular synovitis is characterized by a limited involvement of synovium. Although the knee is the joint that is commonly affected, bone changes in this location are not usual. We report the case of a histologically proven localized form of this entity in the knee, which mimicked a benign bone tumor on the basis of an MR pattern, CT findings, and scintigraphic results.

Computed tomography measurement of humeral head retroversion: influence of patient positioning.

For accurate humeral head arthroplasty, the surgeon needs to know some geometric data, such as, for example, the retroversion angle of the humeral head. Only a few reports have described and evaluated the use of computed tomography (CT) to measure humeral head retroversion. The humerus position relative to the roentgen beam is variable from one subject to another depending on the patients' morphology.

Computed tomography evaluation of shoulder prosthesis retroversion.

Computed tomography (CT) allows calculation of anatomic and prosthetic humeral head retroversion. The purpose of this study was to demonstrate how the retroversion angle measured by CT scan varied with changes in arm position in the CT scan reference system. A trigonometric analysis shows that the measured retroversion angle decreases when the arm is in extension and increases when it is in flexion, compared with the true retroversion angle determined perioperatively.

Biomechanical evaluation of Hackethal's intramedullary bundle pin fixation of humeral neck fractures.

Humeral neck fractures can be stabilized using a bundle of intramedullary pins as described by Hackethal. In order to decrease the risk of pin migration, packing of the medullary cavity with as many pins as possible is sometimes recommended, but others believe that stability can be decreased by destruction of cancellous bone in the humeral head by a large bundle of pins. A surgical neck fracture was created with a saw in 30 frozen cadaveric humeri.

[Shock absorption by intermediate hip prostheses].

Purpose Of The Study: The bipolar prosthesis was developed in an attempt to alleviate acetabular wear of conventional metallic endoprostheses. The prosthesis was designed to achieve low-friction metal-on-polyethylene inner bearing motion while decreasing shear stress across the acetabular cartilage. Although good clinical results were obtained, the principle of a persistent inner mobility was contested and some authors have assigned the delay of cartilage erosion to the shock absorption capacity of the polyethylene.

Geometrical analysis of the femoral neck torsion.

By the geometrical analysis of three cross sections the surface along the femoral neck, the second moments of area and the major axes of symmetry are obtained. The surface passing through these axes determined in each section, from the lateral to the medial third of the neck, is one of the two anatomical surfaces of symmetry of the neck. The geometric structure defined by this surface is a helicoid.

A method to measure acetabular cup anteversion after total hip replacement.

The authors propose a simple and practical method to measure radiologically the angle of ante- or retroversion of the acetabular cup using a goniometer. It only necessitates an anteroposterior radiograph centered on the femoral head and another one centered on the public symphysis. Special x ray equipment, compass, conversion table, mathematical formulas, or a pocket calculator are not required.

[Analysis of the acetabulum anterior cover].

Purpose: The false profile X-Ray view as described by Lequesne, allowing the measurement of the anterior cover of the acetabulum, is a slantwise view obtained by a 65 degrees inclination of the pelvis on the radiographic plate. The errors introduced by this radiological measurement of the anterior cover are evaluated.

Materials And Methods: An anatomical and radiological analysis is conducted on 20 acetabula.

Histopathology of a well-functioning hydroxyapatite-coated femoral prosthesis after 52 months.

A fully hydroxyapatite-coated femoral implant was retrieved during autopsy. This component, provided with a bipolar femoral head, had been inserted for a displaced fracture of the femoral neck 52 months before. Osseointegration of the implant was evident, without any formation of fibrous tissue :39.

Different aspects of the cyclops lesion following anterior cruciate ligament reconstruction: a multifactorial etiopathogenesis.

After anterior cruciate ligament (ACL) reconstruction using a patellar-tendon autograft, 65 patients underwent second-look arthroscopy in conjunction with hardware removal. In 23 patients, hypertrophic tissue was found in the anterior part of the knee. This tissue presented different aspects, from a well-synovialized nodule to a more disorganized fibrous tissue according to patients' complaints.
