Are you in pain?

Welcome to the site of Professor Nicolas Reina, specialist in hip surgery. With recognized expertise in this field, Professor Reina provides high quality care to patients suffering from hip pathologies.

The hip is the joint between the pelvis (iliac bone) and the head of the femur that is essential for mobility and daily movements. The most common pathologies that affect this joint include:

Hip osteoarthritis (coxarthrosis): This degenerative pathology is due to the gradual wear and tear of the articular cartilage, causing significant pain and stiffness. Osteoarthritis can severely restrict movement and affect quality of life. It is a natural phenomenon that occurs with aging but can be favored by certain risk factors such as obesity, certain morphological abnormalities or a traumatic history.

Dysplasie de la hanche : Cette malformation congénitale affecte la couverture de la tête fémorale par l'acétabulum. Ce défaut entraine des contraintes articulaires majorées et peut conduire à une usure prématurée du cartilage si elle n'est pas traitée.

Femoral neck fractures: Typically caused by falls, these fractures are common in older adults and often require rapid surgery to restore mobility and prevent complications.

Conflit fémoro-acétabulaire : Il s'agit d'un contact précoce et anormal entre l'acétabulum (bassin et le col fémoral). Ce frottement provoque des douleurs et peut endommager l'articulation et les structures périphériques (labrum) ce qui peut accélérer les lésions dégénératives. Il est souvent observé chez les jeunes adultes actifs et favorisée par la pratique de certains sports nécessitant de grandes amplitudes articulaires.

Nécrose aseptique de la tête fémorale : Egalement connue sous le nom d'ostéonécrose, est la mort du tissu osseux causée par une perturbation de la circulation sanguine dans la tête fémorale. Elle peut survenir au niveau d'autres articulations. Il existe certains facteurs de risque connus (fractures, luxations, consommation chronique de stéroïdes, consommation chronique d'alcool, coagulopathie, causes congénitales ; parmi beaucoup d'autres).

Hip surgical procedures

Arthroplasty or Total Hip Prosthesis

Total hip arthroplasty is a common procedure performed to replace a damaged hip joint with a prosthesis. For patients with osteoarthritis or who have experienced hip trauma, total hip arthroplasty can restore function and reduce pain. This involves replacing damaged or diseased bone with a metal implant combined with polyethylene and ceramic, designed to replicate the biomechanics of the hip joint.

Hip prosthesis revision

Surgery consists in replacing an existing prosthesis with a new one. Although the lifespan of prostheses is very long (several decades on average), some complications may require new surgery.

This can be caused by a loosening of the prosthesis, wear and tear on the implants, an infection or a fracture, among others.

Fixation/Fracture osteosynthesis

For femoral neck fractures, several techniques are used, depending on the age of the patient, the nature of the fracture, and the condition of the bone:

Osteosynthesis: This method involves fixing the fracture using screws, plates, or nails to allow the bone to heal properly. It is often used in younger patients with good bone quality.

Prosthesis: In older patients or when the fracture is complex, the femoral head may be replaced by a partial prosthesis. This procedure allows for faster recovery and reduces the risk of complications. Intermediate prostheses (as opposed to total prostheses), without implants in the pelvis, are sometimes used in this context for certain fragile patients.

Technologies used ‍

Numerous advanced technologies are used to optimize surgical results and accelerate recovery. Among these technologies:

Planification préopératoire - Imagerie EOS : Ces outils permettent une planification précise et une exécution chirurgicale minutieuse. L'imagerie 3D aide à visualiser l'anatomie complexe de la hanche, tandis que la navigation chirurgicale guide le chirurgien pendant l'intervention, augmentant ainsi la précision.

Techniques mini-invasives: Ces méthodes réduisent la taille des incisions, minimisant les traumatismes et favorisant une récupération plus rapide. Les patients bénéficient de moins de douleur post-opératoire et d'un séjour hospitalier plus court.

Prothèses de nouvelle génération: Fabriquées avec des matériaux biocompatibles, ces prothèses offrent une meilleure longévité et fonctionnalité, en optimisant la conservation du stock osseux. Elles sont conçues pour s'intégrer parfaitement à l'anatomie du patient, offrant ainsi une performance optimale.

Benefits for patients

Key benefits of hip surgery include:

Pain relief: Surgery is primarily aimed at eliminating chronic and disabling pain caused by hip pathologies.

Improving mobility: Patients regain a range of motion and mobility close to normal, allowing them to resume their daily activities without restriction.

Quality of life: A functional and pain-free hip allows patients to participate fully in their leisure time and improve their overall well-being.

Fast recovery: Thanks to modern techniques and appropriate rehabilitation, recovery time is reduced, allowing a faster return to an active life. Patients can often walk as early as the day after surgery using crutches.

Of course, each patient is different and the evolution depends on the preoperative status and the ability of each patient to re-educate himself.

Post-operative care

Post-operative rehabilitation is crucial to maximizing the results of hip surgery. Professor Reina and her team work closely with physiotherapists to develop a personalized rehabilitation program. This program includes exercises to strengthen muscles, improve range of motion, and promote proper walking.

A rehabilitation center is not systematic and functional recovery is generally achieved by combining rehabilitation sessions and self-rehabilitation by resuming daily walking. Patients can generally return to daily activities a few weeks after surgery, although full recovery may take several months. The time to resume activities after hip replacement surgery varies depending on the patient's overall health and the presence of complications.

Deadlines (indicative)
Light activity (walking, stationary bike, etc.) — in the days following surgery

Driving - From 2 weeks

Sedentary work — 2 weeks

Physical work — 6-16 weeks
Sports — 2-3 months depending on the type of sport

Sexual activity - It can be resumed quickly after surgery but avoiding large amounts of hip during the first 3 weeks.
