“…Our subjective results and strength and functional outcomes compare favourably with the published mid-term series of the Maïa® prosthesis (Bricout and Rezzouk, 2016; Jager et al., 2013; Teissier and Alkar, 2011; Toffoli and Teissier, 2017) as well as other implants (Apard and Saint-Cast, 2007a; Cootjans et al., 2017; Dehl et al., 2017; Maes et al., 2010; Martin-Ferrero, 2014.…”

“…Semi-constrained cups provide stability that can help to prevent early dislocation during the initial period of tissue healing (Daunois et al., 2011). However, the most important factor for prosthesis stability is adequate placement centrally in the bone and within the centre of joint mobility (Bricout and Rezzouk, 2016; Ledoux, 1997). In this series of Maïa® prostheses with unconstrained cups, intra-operative fluoroscopy was systematically used to optimize cup placement, following the guidelines of Duerinckx and Caekebeke (2016).…”

“…Regardless of the type of prosthesis, most failures and revisions are due to loosening or dislocation. A deformed thumb before surgery and the position of the trapezial cup are the most important contributing factors (Bricout and Rezzouk, 2016; Ledoux, 1997). In an attempt to improve post-operative results, guidelines for correct cup positioning have recently been described (Duerinckx and Caekebeke, 2016).…”

“…However, there are also many reports of poor results [10]. Revisions are most often due to the loosening of the trapezium cup [11,12] and of the metacarpal stem and to the luxation of the first metacarpal bone [13] (Figure 3).…”

Total prosthesis, which preserves strength and respects trapeziometacarpal (TMC) joint range of motion, is a surgical option considered for the TMC joint replacement. With the usual ball-and-socket design, patients obtain faster pain relief, stronger grip function, and shorter convalescence than with trapeziectomy. However, prostheses currently used have led to various early complications, especially in active and young patients. Revisions are most often due to the loosening of the trapezium cup and of the metacarpal stem and to the luxation of the first metacarpal bone. The short lifespan of these devices suggests the difficulty of designing a prosthesis that respects the complex anatomy and motions of the TMC joint. Early implant failure may reflect the fact that the current devices do not exactly replicate the true kinematics. The aim of this chapter will be to shed light mechanical explanations for TMC prosthesis failures in regard to the complex kinematics of the joint.

“…A certain macrostructure on the stem and strong cortical support further improve stability (Apard and Saint-Cast, 2007). In two series of the Maïa prosthesis where the stems were placed with cortical contact, no cases of subsidence have been reported with a minimal follow-up of 3 years (Bricout and Rezzouk, 2016; Teissier and Alkar, 2011). In our series, the same prosthesis was implanted, but only 23% of our stems had cortical contact on postoperative radiographs.…”

swelling might be localized to the snuffbox, but since the patient is unlikely to know which bone is supposed to be broken, there might be other exaggerated signs, such as rigidity of the wrist and a level of subjective pain out of proportion upon range of motion testing. Additionally, the common signs of scaphoid fracture, such as scaphoid tuberosity tenderness on the palmar side, might be absent or poorly localized. Our experience is that the patient's personality and history of injury, given in the bullet points mentioned, play key roles in the diagnosis. Malingering will persist if the malingerer believes it will produce the desired rewards. The feigned symptomswill disappearonce therewards havebeenattained (Sadock et al., 2004). The management of this type of presentation is controversial and additional problems are raised when it occurs in the military setting. Strategies range from tactfully but firmly confronting patients about their behaviour and its consequences to allow the patient to 'save face', as direct confrontation will likely result in the avoidance of contact with medical services. It is not our purpose to discuss treatment, but rather to draw attention to the presentation. In our experience, management of a suspected spurious injury should always include a full workup consisting of past and current medical history and a physical examination. Radiographs are mandatory, especially during the first encounter with the patient for the given injury. The higher occurrence of true scaphoid fractures in the military population compared with the civilian population should also be borne in mind (Wolf et al., 2009).
