Radiographic Assessment of the Robert and Lateral Views in Trapeziometacarpal Osteoarthrosis

Abstract

This study confirms that each of the Robert and lateral views offer unique information and combining both views enhances the ability to assess radiographic disease severity, and should be the recommended set of X-rays for assessing TM osteoarthrosis.

Dorsoradial Capsulodesis for Stage I Trapeziometacarpal Joint Arthrosis

“…2 Radiographic evaluation at follow-up included posterior-anterior, Robert hyperpronation, and TM stress views to assess the degree of subluxation or onset of arthritis and to compare with preoperative radiographs for progression of disease. 4,22…”

“…2 Forearm pronation radiographic Robert views, described by Oheb et al, are valuable in assessing patient’s degree of TM joint arthrosis and subluxation, which also has the potential for assessment of TM joint instability. 4…”

“…2 Forearm pronation radiographic Robert views, described by Oheb et al, are valuable in assessing patient's degree of TM joint arthrosis and subluxation, which also has the potential for assessment of TM joint instability. 4 Several factors predispose to TM joint instability including generalized physiologic joint hypermobility, congenital disorders such as Ehlers-Danlos and Marfan syndromes, 3 residuals of acute trauma, 5 long-standing repetitive pinching, thenar muscle atrophy, 6 anomalous abductor pollicis longus insertion, 7 and spastic disorders, such as cerebral palsy.…”

Factors Associated With Radiographic Trapeziometacarpal Arthrosis in Patients Not Seeking Care for This Condition

“…Our primary outcome measure was radiographic TMC arthrosis grade according to the Eaton classification. 11,18 One of the attending surgeons, blinded to the patient’s identity, graded the radiographs for each patient. This outcome variable was categorized as either Eaton grade I, grade II, or grade III/IV; we chose to consolidate stages III/IV into one group as our focus was on the TMC joint and not the scaphotrapezotrapezoidal (STT) joint.…”

Current trends in the management of trapeziometacarpal arthritis

“…recommend obtaining a combination of both lateral and Robert-hyperpronation X-ray views to enhance assessment of radiographic disease severity. 8 Several different methods exist for the radiographic staging of TMC arthritis, and Ladd et al . compared the Eaton, modified Eaton, and thumb osteoarthritis (ThOA) index staging classification methods in thumb radiographs from 60 adults patients with asymptomatic to advanced disease.…”
