Overview¶

• The Touch® trapeziometacarpal joint arthroplasty demonstrated a 96% implant survival rate at 2 years [4].
• The Touch® prosthesis is recommended as the standard treatment for patients with isolated trapeziometacarpal joint osteoarthritis [4].
• The Touch1 prosthesis is a safe and stable implant providing good satisfaction and very good functional scores [7].
• Patients using the Touch1 prosthesis experience a fast return to work and leisure activity [7].
• Trapeziometacarpal prosthesis enhances function, thumb length, and patient recovery [2].
• Total joint arthroplasty for primary trapeziometacarpal joint arthritis results in low pain levels, excellent mobility, and high patient satisfaction [10].
• The MAÏA trapeziometacarpal prosthesis is a reliable long-term surgical procedure that improves overall function beyond 10 years [23].
• The MAÏA TMC total joint arthroplasty provides very good results for pain relief, strength, mobility, and restoration of thumb length [13].
• The MAÏA TMC total joint arthroplasty provides correction of most thumb z-deformities [13].
• The Elektra prosthesis had a revision rate of 44% after 72 months [1].
• The Elektra prosthesis is not recommended due to poor outcomes observed after only 2 years [8].

• The Moovis prosthesis is recommended for the treatment of advanced trapeziometacarpal osteoarthritis in patients without too many manual constraints [5].
• Dual mobility arthroplasty for thumb CMC joint osteoarthritis is a satisfactory solution with good functional results and absence of early and middle term dislocations [12].
• The Ivory arthroplasty is a reliable option for treating advanced trapeziometacarpal osteoarthritis, providing important improvement in overall function and pain reduction [15].
• Not every complication associated with the Ivory prosthesis requires surgical revision [14].
• Correct implant position leads to reliable medium-term results after trapeziometacarpal joint arthroplasty [11].
• Limiting the magnitude of thumb loads after arthroplasty may contribute positively to the longevity of the procedure [3].
• Scaphometacarpal arthroplasty using a trapeziometacarpal prosthesis is not sufficiently reliable to be a routine solution for surgical revision of failed TMC arthroplasty or trapeziectomy [21].
• Scaphometacarpal arthroplasty using a trapeziometacarpal prosthesis should be used with caution, primarily as a salvage solution if no safer alternative is available [21].
• The Touch® prosthesis is compatible with the Ivory® trapeziometacarpal prosthesis stem during revision surgery [16].
• If the trial neck does not align with the centre of the trapezium, the cup position should be dictated by the neck to represent the new centre of rotation [17].

Anatomy & Pathophysiology¶

Bony Anatomy¶

• The skeleton of the hand consists of 27 bones, of which 19 are long bones [30].
• The radial ray or first ray is the shortest and is made up of only three bones: a metacarpal and two phalanges [30].
• The trapezium is clearly angled out in front of the carpal plane so that the first metacarpal makes an angle of about 45 degrees with the second metacarpal in the sagittal plane [30].
• The thumb metacarpal is independent and articulates with the trapezium [36].
• The base of each metacarpal articulates with the distal row of the carpus [30].
• The thumb ray continues the external column of the carpus formed by the scaphoid and trapezium [30].

Joint Mechanics & Kinematics¶

• The trapeziometacarpal joint has a saddle shape in opposing planes of the articular surfaces [30].
• The first metacarpal makes an angle of about 45 degrees with the second metacarpal in the sagittal plane, which explains the gap between the first ray and the palm [30].
• The thumb ray is more mobile, shorter, and more proximal than the other rays, allowing it to project in front of the plane of the palm to oppose itself to the other four rays [30].
• The wrist has three axes of movement, permitting the hand to be positioned in any spatial configuration [30].
• The combined movements of the wrist and forearm place the hand in a position for grasping [31].
• The thumb has a more proximal and lateral position, allowing movement inward and outward from the palm [31].

Musculature & Tendon Anatomy¶

• The first (most radial) extensor compartment contains the abductor pollicis longus and the extensor pollicis brevis [29].
• The abductor pollicis longus inserts at the base of the thumb metacarpal and radially abducts the thumb [29].
• The extensor pollicis brevis inserts on the dorsum of the proximal aspect of the proximal phalanx of the thumb and actively extends the metacarpophalangeal joint of the thumb [29].
• The extensor pollicis longus runs longitudinally down the forearm through the third compartment and turns abruptly radialward about Lister tubercle [29].
• The extensor pollicis longus inserts on the distal phalanx and provides forceful extension of the thumb interphalangeal joint [29].
• The flexor pollicis longus originates from two heads: a radial head from the proximal radius and interosseous membrane, and an accessory head from the coronoid process of the ulna and medial epicondyle of the humerus [40].
• The flexor pollicis longus inserts into the proximal base of the thumb distal phalanx and is innervated by the anterior interosseous branch of the median nerve [40].
• The flexor pollicis longus flexes both the interphalangeal and metacarpophalangeal joints of the thumb [40].
• The tenosynovial sheath of the flexor pollicis longus is continuous with the radial bursa [40].

Vascular Anatomy¶

• The "princeps pollicis" artery, a terminal branch of the radial artery, crosses the first intermetacarpal space and runs along the ulnar side of the first metacarpal bone [37].
• The princeps pollicis artery emerges onto the subcutaneous palmar tissue at the level of the cutaneous flexion crease of the metacarpophalangeal joint [37].
• The princeps pollicis artery divides into two terminal rami, the collateral palmar arteries of the thumb, which run along the digital tunnel symmetrically [37].
• An arcade located deep in the flexor tendon joins together the two palmar arteries at the level of the distal metaphysis of the first phalanx [37].
• The dorsal arteries of the thumb originate from terminal branches of the radial artery at the level of the anatomical snuff-box [37].
• The posterior area of the thumb is vascularized by two arteries which originate from the palmar arteries at the level of the first metacarpal [37].

Soft Tissue & Skin Anatomy¶

• The superficial palmar fascia covers a triangular area of the central palm, with no central band for the thumb [43].
• The dorsal skin of the hand is thin and possesses loose connections with deeper planes, allowing free gliding [42].
• The palmar integument is subdivided into two separate zones by the oppositional crease of the thumb [32].
• The skin of the radial portion of the palm covers the thenar eminence and is the mobile portion [32].
• The skin of the ulnar and distal portion covers the hypothenar eminence where the skin has poor mobility [32].
• The web spaces are formed from the union of two nonsymmetrical cutaneous surfaces, with the palmar surface being flat and densely adherent to the commissural skeleton [32].
• The distal transverse ligament at the level of the thumb web is the deepest and most mobile commissural skeleton [32].

Prosthesis Design & Biomechanics¶

• The Touch® prosthesis consists of a mobile prosthetic head in a polyethylene insert that is freely moveable within a metal cup [22].
• The Touch® prosthesis comprises two concentric articulations: a smaller articulation between the head and polyethylene insert, and a larger articulation between the polyethylene insert and metal cup [22].
• The Touch® prosthesis uses metal-on-polyethylene bearings [22].
• The Touch® prosthesis is modular, composed of a titanium alloy stem (Ti–6Al–4 V), an M30 stainless steel intermediate implant, and an M30 stainless steel hemispheric cup [22].
• The Touch® prosthesis head has a 4-mm diameter covered by a pre-assembled high-density 7-mm diameter polyethylene insert [22].
• The Touch® prosthesis cup is available in two sizes: 9 and 10 mm in diameter [22].
• Implant fixation for the Touch® prosthesis is primary by a press-fit effect and secondary by means of a double-layer porous titanium and hydroxyapatite coating [22].
• The total in vitro range of motion of the Touch® prosthesis is 117 degrees [22].

Classification¶

• The Touch® prosthesis reproduces the dual mobility concept consisting of a mobile prosthetic head in a polyethylene insert that is freely moveable within a metal cup [22].
• The Touch® prosthesis utilizes metal-on-polyethylene bearings [22].
• The Touch® prosthesis stem is available in five sizes [22].
• The Touch® prosthesis intermediate implant has a 4-mm diameter head covered by a pre-assembled high-density 7-mm diameter polyethylene insert [22].
• The Touch® prosthesis polyethylene insert is available in three lengths and two angles [22].
• The Touch® prosthesis hemispheric cup is available in two sizes: 9 and 10 mm in diameter [22].
• The double-layer porous titanium and hydroxyapatite coating promotes and accelerates osteointegration [22].

Clinical Presentation¶

• A 53-year-old male professional cook presented with persistent clicking during thumb motion 12 months after Touch trapeziometacarpal arthroplasty [18].
• The patient reported no antecedent trauma or pain associated with the clicking noise [18].
• Grip and pinch strength were clinically evaluated and showed no difference compared with the opposite side [18].
• Standard radiographs taken 1 year after surgery did not demonstrate loosening of the implant [18].
• Computed tomography (CT) scan demonstrated a well-aligned implant without evidence of loosening [18].
• CT scan revealed a hint of a very small bone cyst but no loosening of the cup [18].
• Stress-view imaging using a fluoroscopic image intensifier revealed instability of the carpometacarpal I joint during the application of translatory stress forces on the thumb [18].
• Stress-view imaging showed a hint of possible decentralization of the head compared with the cup [18].
• The new diagnosis based on imaging was a fracture of the polyethylene (PE) liner [18].
• Revision surgery confirmed a fractured PE liner with an intact metallic head and stem [18].
• Exchanging only the liner restored stability [18].
• Follow-up radiographs 6 weeks after revision surgery confirmed the implant position remained satisfactory [18].
• Dynamic radiographic imaging with longitudinal traction is important for making a timely diagnosis of polyethylene liner fracture when standard radiographs are normal [20].

Investigations¶

• Standard radiographs (x-ray) are used to evaluate preoperative osteoarthritis and postoperative implant position, including stem subsidence, periprosthetic radiolucent lines, osteolysis, implant fracture, polyethylene wear, periprosthetic ossifications, and prosthetic dislocation or subluxation [27].
• Subsidence of the metacarpal component is evaluated by comparing the A/B ratio in percentage on strict lateral views immediately after surgery and at the last follow-up [27].
• A difference of more than 25% in the A/B ratio on strict lateral views is indicative of implant subsidence [27].
• Computed tomography (CT) scans can demonstrate a well-aligned implant without evidence of loosening even when clinical symptoms such as clicking are present [18].
• Stress-view imaging (dynamic x-ray) using a fluoroscopic image intensifier can reveal instability of the carpometacarpal I joint and possible decentralization of the head compared with the cup during the application of translatory stress forces [18].
• Preoperative assessment includes evaluation of the scaphotrapeziotrapezoid (STT) joint and confirmation of the absence of other thumb affections [27].
• Osteoarthritis is assessed preoperatively on standard anteroposterior and lateral radiographic views using the Eaton classification [27].

Treatment¶

Implant Design and Biomechanics¶

• The Touch® prosthesis head has a 4-mm diameter and is covered by a pre-assembled high-density 7-mm diameter polyethylene insert [22].

Surgical Technique¶

• A dorsolateral approach is used, protecting the superficial branch of the radial nerve and artery [25].
• The first dorsal compartment is released routinely, and the TMJ capsule is exposed between the extensor pollicis brevis and abductor pollicis longus tendons [25].
• A complete circumferential soft tissue release of the thumb metacarpal base is performed, including resection of the volar lip to facilitate delivery of the metacarpal base out of the wound [25].
• Osteophytes on the base of the metacarpal and the trapezium are resected to reduce the risk of impingement and dislocation [25].
• The distal articular surface of the trapezium is cut to be parallel with the STT joint [25].
• A K-wire is inserted under image guidance, centred in the trapezium, and the trapezium is reamed over the wire as recommended by the manufacturer [25].
• The MAÏA® dual mobility hemispherical cup is inserted with spikes facing the four corners of the trapezium to provide rotational stability [25].
• Attentive reaming of the trapezium and careful cup impaction are crucial steps to avoid trapezial fracture and early cup failure [19].
