Study summary

The aim of this study is to collect boh clinical and radiographic data coming from the treated patients for pseudarthrosis of the upper limbs from 2000 to 2017 at the SC Orthopedic Surgery, Innovative Techniques of the Istituto Ortopedico Rizzoli in order to evaluate the clinical and radiographic outcomes of the treatment, with or without the application of biological adjuvants.

Read the detailed description

The bone healing requires the integrations of two main principles: biomechanical aspect and biological aspect. The second one has having growing interest.

The use of the biological adjuvants, as growth factors (rhBMP2 and 7), platelet-derived growth factors (PDGFs), Platelet gel (PG) or Plasma Rich Fibrin (PRF), as well as peptides and molecules are demonstrating promising results in the field of bone regeneration.

The addition of autologous bone marrow concentrate cells has proven to be an effective option in the treatment of bone defects, although to date there is no clear superiority of one method over the other.

In light of this, the purpose of the study is to evaluate the clinical and radiographic outcomes of the treatment, with or without the application of biological adjuvants, collecting data coming from the treated patients for pseudarthrosis of the upper limbs from 2000 to 2017 at the SC Orthopedic Surgery, Innovative Techniques of the Istituto Ortopedico Rizzoli

Study population

Patients surgically treated from 2000 to 2017 at the Innovative Techniques Orthopedic Surgery - Musculoskeletal Tissue Bank (BTM) of the Istituto Ortopedico Rizzoli for pseudoarthrosis of the upper limb (with or without biological adjuvants)

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with post-traumatic pseudoarthrosis of the long bones of the upper limb
  • Duration of at least 6-9 months without clinical-radiographic signs of healing in the 3 months prior to pseudoarthroses

Exclusion criteria

Exclusion Criteria:

  • Pseudoarthrosis due to pathological fracture
  • Infected pseudarthrosis
  • Pseudoarthrosis treated with external fixation
  • > 35
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

What researchers measure

Primary outcomes

  1. Pseudoarthrosis Radiographic Healing Score (PRHS)

    Numeric score rapresenting presence or absence of bone callus. The score range from 0 to 4, with 0 score rapresent absence of bone callus and no bone graft integration, and 4 presence of bone callus and completed bone graft integration.

    Time frame: 12 months
