Visão geral do estudo

Descrição detalhada
For determine the normal kinematics of the thumb carpometacarpal (CMC) joint, Imaeda et al. (1994) examined in specimens four conditions which simulated normal function of the thumb: a) passive circumduction, b) active circumduction, c) static loading, and d) single-axis loading. Changes in normal kinematics predispose the CMC joint to osteoarthritis (OA). Previous studies used radiographic techniques that usually were static or measured the end range of motion.
For thumb CMC joint OA the prosthesis or total joint arthroplasty is one of the surgical option. Murai (2022) studied in ten healthy men with reconstruction 3D bone models the optimal center of rotation of the implant and found that the center of rotation change across various thumb positions. In the study by D´Agostino et al. (2018) a CT scan was used to quantify the 3D thumb kinematics in four female patients, before and after trapeziometacarpal joint replacement surgery with the Arpe implant. Thumb CMC joint OA led to a marked decrease of internal rotation and abduction of the first metacarpal during thumb flexion and a decrease of metacarpal adduction during thumb adduction. The abcense of first metacarpal translation in the ball-and-socket implant seems to indicate a decrease of first metacarpal adduction. Advanced thumb CMC joint OA mainly restrict the first metacarpal mobility. Whereas prosthesis is able to restore thumb function, it cannot fully replicate the kinematics of the healthy trapeziometacarpal joint.
This study will include 40 adults patients with chronic pain and carpometacarpal osteoarthritis that need surgical intervention. For the biomechanical evaluation, 3D modeling and finite element methods of evaluation of the CT scan before and after the surgical intervention in each patient will be performed with the computed specific software Epylisis and Ansys in Dimension Lab 3D, Hospital de la Santa Creu i Sant Pau by biomedical engineers.
The source of information is the journals and journals specialized in hand surgery, bioengineering, biotechnology and biomedical engineering.
The principal investigator and collaborators are responsible for creating the database and entering data. Statistical analysis requires support from the statistics unit of the UICEC/Hospital de la Santa Creu i Sant Pau. All data will be collected in REDCap.

Chronic pain and Thumb carpometacarpal (CMC) osteoarthritis: Suspension-resection arthroplasty
This is a usual surgical treatment for patients with chronic pain and thumb CMC joint osteoarthritis. The clinical management of the patients will be adapted to the treatment standards of the Orthopedic Surgery and Traumatology Service of the Hospital de la Santa Creu i Sant Pau, without the performance of this study influencing this process. Procedure performe with a suspension-resection arthroplasty by modified Welby´s technique. Dorso-lateral approach. Complete resection of the trapezium and joint stabilization with tendon interposition arthroplasty. After resection a distally based strip of the Abductor Pollicis Longus tendon is looped along the Flexor Carpi Radialis tendon. After surgical intervention the immobilization is one month with a plaster cast. |

Chronic pain and Thumb carpometacarpal (CMC) osteoarthritis: Trapeziometacarpal joint prosthesis
This is a usual surgical treatment for patients with chronic pain and thumb CMC joint osteoarthritis. The clinical management of the patients will be adapted to the treatment standards of the Orthopedic Surgery and Traumatology Service of the Hospital de la Santa Creu i Sant Pau, without the performance of this study influencing this process. Procedure performe with a thumb CMC joint prosthesis. Dorso-lateral approach. Insertion of a dual mobility trapeziometacarpal joint prosthesis. The Prosthesis consists of a hemispherical cup, a modular neck and of an anatomical metacarpal stem. It offers a complete range of implants allowing the choice between single and double mobility. After surgical intervention the immobilization is one month with a plaster cast. |

Thumb carpometarcarpal joint radiological evaluation
Prazo: 12 months
|
Standard radiographs are required x-rays in posteroanterior (PA), PA in pronation (Robert´s view) and lateral views for assessment of the radiological stages of Eaton-Littler modified by Eaton-Glicker classification (1973).
This classification include four stages of progression of the loss cartilage in thumb CMC joint, from I to IV.
The X-rays will made in clinics at 6 weeks, 3 months, 6 months and 12 months after the surgical repair.

Thumb carpometacarpal joint CT scan evaluation
Prazo: 12 months

A Computed Tomography (CT) scan is also required for the initial evaluation and regular control of these patients.
For each participant, CT scans will be perform in static limb positions before and after the surgery.

3D modeling and finite element methods of evaluation of the CT scan before and after surgical intervention.
Prazo: 12 months
|
In each patient will be performed with the computed specific software Epylisis and Ansys in Dimension Lab 3D, Hospital de la Santa Creu i Sant Pau by biomedical engineers. To obtain the 3D geometrical information for a subject-specific finite element human hand, CT images will take from patients. Each scan is recontructed in a Digital Imaging and Communications in Medicine (DICOM) format. These 2D data (DICOM data collection) are process using medical image processing software Mimics (Materialise, Leuven, Belgium). All the CT images will be segmented manually into the bones and skin, while subcutaneous tissues and tendons will be reconstructed based on CT images. A specific software (Epylisis, Ansys) will be used to simulated the loads in the thumb CMC joint. Epylisis is one of this specific software based on the Finite Element Methods (FEM), enables computational simulation of the biomechanical behavior of the trapeziometacarpal joint. It is used to conduct mechanistic analyses |
