Our Philosophy

Not every shoulder condition requires an operation. Dr. Hachem’s clinical philosophy is rooted in a highly personalized, careful assessment of each patient's specific injury, lifestyle, and goals.

Every consultation begins with an exhaustive physical examination and a detailed review of medical imaging. Whenever possible, Dr. Hachem prioritizes effective conservative treatments first—partnering with specialized physiotherapists for targeted rehabilitation, biomechanical corrections, and localized infiltrations.

Dr. Abdul-ilah Hachem speaking at BIASS 2025, Barcelona International Arthro Shoulder Course, a shoulder surgery course which he organizes in Barcelonam, held on November 2025 at Bellvitge University Hospital.

Surgical intervention is only recommended when conservative measures have been fully exhausted, or when structural damage (such as massive tendon tears, severe instability, or complex fractures) strictly requires it to restore function and eliminate pain. When surgery is the clear path forward, patients benefit from his world-renowned, minimally invasive techniques.

    Shoulder Instability

    Joint Instability & AC Dislocations

    • Focus: Recurrent shoulder dislocations, glenoid bone loss, and acromioclavicular separations.

    • Innovation: Comprehensive knotless double cerclage techniques and glenoid reconstructions for high-demand athletes and patients.

    Complex Rotator Cuff Disease & Tendon Transfers

    Repairable and non-repairable rotator cuff pathologies

    • Focus: Massive, irreparable rotator cuff tears and revision surgeries.

    • Innovation: Specialized in Lower Trapezius Tendon Transfer utilizing arthroscopic Achilles allograft fixation—pioneering nerve safety techniques published in JSES.

    Shoulder Arthroplasty & Prosthetics

    Arthritis and Deformities

    • Focus: Severe osteoarthritis, complex humerus fractures, and joint degeneration.

    • Innovation: Award-winning clinical research on Reverse Total Shoulder Arthroplasty (RSA), utilizing 3D pre-operative planning and custom stem angles to maximize functional recovery.

    Adhesive Capsulitis (Frozen Shoulder)

    Conservative and Surgical Treatment

    • Focus: Severe shoulder stiffness, chronic pain, and restricted range of motion resulting from joint capsule inflammation.

    • Innovation: Expert implementation of targeted conservative protocols. For recalcitrant cases that do not respond to physical therapy, Dr. Hachem utilizes advanced, minimally invasive arthroscopic capsular release (lysis of adhesions) to immediately restore joint mobility and accelerate recovery.

    Complex Trauma & Fracture Care

    Acute proximal humerus fractures, clavicle nonunions, periprosthetic fractures, and severe shoulder trauma

    • Focus: Internationally recognized, award-winning protocols for treating complex shoulder fractures. Dr. Hachem utilizes specialized 3D planning and specific stem angles in RSA to optimize tuberosity healing and restore maximum function after catastrophic joint trauma.

    • Innovation: Furthermore, he pioneers the use of intramedullary tendon allografts for complex clavicle nonunions.

The Bone Block Cerclage

Pioneering minimally invasive techniques, metal-free reconstructions, and evidence-based shoulder care to restore mobility and eliminate pain.

  • The Patented Metal-Free Bone Block Cerclage System

    When treating severe or recurrent anterior shoulder dislocations, traditional surgical approaches rely on metal screws to anchor bone grafts. While functional, metal hardware carries long-term risks of cartilage abrasion, hardware breakage, screw migration, or joint stiffness.

    Dr. Hachem developed and patented a groundbreaking, metal-free solution: the Arthroscopic Bone Block Cerclage. Performed via minimally invasive arthroscopy, this technique utilizes high-strength, suture-tape cerclage to securely fix the graft in place.

  • Key Patient Benefits (Bullet Points):

    • 100% Hardware-Free: Eliminates metal-related joint friction and future hardware complications.

    • Minimally Invasive: Smaller surgical incisions, reduced tissue trauma, and less post-operative pain.

    • Zero Risk of Screw-Induced Arthritis: Protects surrounding joint cartilage over the long term.

    • No Secondary Surgeries: Eliminates the need to ever return to surgery simply to remove irritating metal implants.
