The history of anatomy teaching in Lyon University: in the footsteps of Rabelais, Petit, Lisfranc, Testut and Latarjet, and many others.

Anatomy and Lyon have a very long history together since the first hospital in France was set up on the banks of the Saône River in the fourteenth century. The Lyon school of Anatomy was originally in the Hôtel-Dieu, which later housed the "secondary" (1821) then "preparatory" (1841) schools. Only in 1877 was the Medicine and Pharmacy Faculty set up.

Total hip arthroplasty with minimal invasive surgery in elderly patients with neck of femur fractures: our institutional experience.

The purpose of this study was to investigate whether minimal invasive surgery (MIS) in elderly patients with neck of femur fractures would reduce the peri-operative complications and improve the post-operative ambulation and length of hospital stay in his cohort of patients. Forty elderly patients were treated with either total hip arthroplasty (THA) or bipolar prosthesis using MIS transgluteal approach. A matched reference group treated with a conventional surgical approach formed the control group.

Acetabular reconstruction using a Kerboull cross-plate, structural allograft and cemented dual-mobility cup in revision THA at a minimum 5-year follow-up.

The current study aimed to evaluate the outcome of a continuous and prospective series of 61 revision THAs with AAOS grade III and IV acetabular bone defect reconstruction using a Kerboull cross-plate, structural allograft and cemented dual mobility cup (Saturne, Amplitude, Valence, France). At a 7.5-year mean follow-up, no instability was reported after revision.

Hip squeaking: a 10-year follow-up study.

The aim of the study was to analyze the incidence of squeaking with ceramic-on-ceramic total hip arthroplasty (THA) after 10 years of follow-up and the potential complications that could occur related to this phenomenon. One hundred THAs implanted between November 1999 and December 2000 were evaluated. Incidence of squeaking was investigated clinically with a questionnaire.

Nine years follow-up of 100 ceramic-on-ceramic total hip arthroplasty.

The aim of this study was to evaluate the first 100 cementless ceramic-on-ceramic total hip arthroplasty (THA) performed at our institution with more than nine years of follow-up. Clinical evaluation was performed using Harris hip score. Radiological evaluation was performed by two surgeons.

Dual mobility design use in preventing total hip replacement dislocation following tumor resection.

Introduction: Total hip replacement (THR) following hip tumor resection incurs a high risk of dislocation. We assessed the incidence of dislocation associated with use of a dual mobility cup,and the functional results achieved.

Hypothesis: Use of a dual mobility cup would reduce the risk of THR instability following hip tumor resection.

Cementless total hip arthroplasty in Paget's disease of bone: a retrospective review.

Paget's disease of bone (PDB) is a localised chronic osteopathy leading to bone deformities, bone hypervascularity, structural weakness and altered joint biomechanics. The pelvis and upper femur are frequently involved, resulting in disabling hip disease, and total hip arthroplasty (THA) may be required. We performed a retrospective study on the management and the outcome of 39 uncemented hydroxyapatite fully-coated THA in patients with PDB of the hip.

[Total hip arthroplasty after hip arthrodesis performed for septic arthritis].

Purpose Of The Study: Revision total hip arthroplasty (THA) after hip arthrodesis is an uncommon and challenging operation. The task would appear to be even more difficult if the arthrodesis was performed because of septic arthritis due to the theoretical risk of recurrent infection. We report our fifteen-year experience.

Unconstrained tripolar implants for primary total hip arthroplasty in patients at risk for dislocation.

We performed a retrospective study on 167 primary total hip arthroplasty (THA) procedures in 163 patients at high risk for instability to assess the reliability of unconstrained tripolar implants (press-fit outer metal shell articulating a bipolar polyethylene component) in preventing dislocations. Eighty-four percent of the patients had at least 2 risk factors for dislocation. The mean follow-up length was 40.

[Total hip arthroplasty in patients with chronic renal failure transplant or dialysis].

Purpose Of The Study: Total hip arthroplasty (THA) is generally proposed for renal transplant patients with invalidating hip disease. For patients on chronic dialysis, the few published series report a higher rate of complications. These patients are considered more vulnerable.

Limb salvage in proximal humerus malignant tumors: the place of free vascularized fibular graft.

Limb-salvage surgery has become a safe and well-established alternative to amputations for malignant tumors of the proximal humerus. The authors describe six cases with favorable restoration of the upper limb following tumor resection type IB Malawer and proximal humeral reconstruction by vascularized fibula graft (VFG) as a primary or secondary procedure. A scapulofibular arthrodesis was elected in all cases.

[Desmoplastic fibroma or bone desmoid tumor: two cases].

Desmoplastic fibroma or desmoid bone tumor is a rare tumor described for the first time by Jaffe in 1958. It accounts for 0.1 to 0.

[Total hip arthroplasty after treatment of acetabular fracture].

Purpose Of The Study: The aim of this retrospective analysis was to examine complications and technical difficulties observed during implantation of total hip arthroplasty (THA) after treatment of an acetabular fracture.

Material And Methods: Forty patients (thirty men and ten women), mean age 50 years, were included in the study. The acetabular fracture had been treated surgically in 23 and orthpedically in 17.

Effect of micro- and macroporosity of bone substitutes on their mechanical properties and cellular response.

The control of porosity morphology and physico-chemical characteristics of calcium phosphate bone substitutes is a key-point to guaranty healing success. In this work, micro- and macroporosity of materials processed with 70% Hydroxyapatite (HAP) and 30% beta-tricalcium phosphate (beta-TCP) were controlled by sintering temperature and porogen addition, respectively. Porosity was quantified by scanning electron microscopy (pore size) and mercury intrusion porosimetry (interconnection between pores).

Conformity to clinical practice guidelines, multidisciplinary management and outcome of treatment for soft tissue sarcomas.

Background: The primary management of adult soft tissue sarcomas (STS) is characterized by heterogeneity across centers. Several studies suggest that it is improved when coordinated by specialized sarcoma centers.

Patients And Methods: This study, comparing STS patients of the Rhône-Alpes region treated within and outside the cancer network, retrospectively assesses the conformity of medical practice with 'evidence-based medicine' (EBM) reported under the clinical practice guidelines (CPGs) of the French Federation of Cancer Centers.

[Cellular culture of osteoblasts and fibroblasts on porous calcium-phosphate bone substitutes].

Purpose Of The Study: Calcium phosphate ceramics are synthetic bone substitutes able to fill in bone destruction as a support of the bone growth. This work consisted in an in vitro assessment of osteoblasts and fibroblasts cultures on macroporous calcium-phosphate bone substitutes to analyze the interaction between cells and bone substitute.

Materials And Methods: The macroporous ceramic was composed of 70% hydroxyapatite and 30% tri-calcium phosphate with known mechanical and physico-chemical properties.

[Surgical treatment of acetabular fractures: outcome in a series of 60 consecutive cases].

Purpose Of The Study: The aim of this study was to analyze clinical and radiographic results after surgical treatment of acetabular fractures.

Material And Methods: We reviewed 60 consecutive fractures of the acetabulum with loss of joint congruency at mean 5-years follow-up after treatment. There were 49 men and 11 women, mean age 41 years.

[Unstable pelvic ring fracture: osteosynthesis of the posterior lesion by percutaneous sacroiliac fixation].

Purpose Of The Study: We report our experience with percutaneous sacroiliac screwing for unstable pelvic ring fracture.

Material And Methods: Twenty unstable pelvic ring fractures with sacroiliac disjunction (9 cases), trans-sacral fracture (9 cases), or bilateral posterior fractures (5 cases) were managed with percutaneous sacroiliac fixation using 1 or 2 screws. There was also pubic disjunction in 7 cases, managed by osteosynthesis in 5 cases.

Radiologic anatomy of the spinal dorsal horn at the cervical level (anatomic-MRI correlations).

The spinal dorsal horn is known for its important functional role in the field of transmission and modulation of sensory afferents. Because of this, the dorsal horn represents a target for numerous analgesic and antispastic procedures. Thus, it would be interesting to develop imaging dedicated to this spinal structure.
