Injuries to the carpometacarpal (CMC) joints are uncommon injuries and isolated dislocation of these joints occurs very infrequently. The 4th and 5th CMC joints are predominantly involved in CMC joint injuries. The detection of CMC joint injuries requires a high index of suspicion and often depends on special radiographic views. This article present a case report of a mid-shaft fracture of the 4th metacarpal which was associated with an isolated dislocation of the 5th CMC joint. An overview of the incidence, mechanism of injury, anatomy, clinical and radiological assessment of injuries involving dorsal dislocation of the 5th carpometacarpal joint is presented.

Background Thumb carpometacarpal (CMC) joint arthroplasty is a common procedure in the surgical management of symptomatic thumb basal joint arthritis. Following trapeziectomy, a number of suspensionplasty techniques are often used, but limited comparative evidence exists between these techniques. The central aim of this study was to prospectively compare the outcomes of 2 suspensionplasty techniques following trapeziectomy: suture button (TightRope) versus ligament reconstruction and tendon interposition (LRTI). Methods Prospective data were collected on 112 consecutive patients with Eaton stage III-IV thumb CMC arthritis who underwent open trapeziectomy and suspensionplasty. There were 53 LRTI and 59 TightRope suspensionplasty procedures. Outcomes were measured using the Quick Disabilities of the Arm, Shoulder, and Hand ( QuickDASH) questionnaire, Visual Analogue Scale (VAS) for pain, radiographic analysis, and lateral pinch strength. Patient demographic data and complications were also recorded. Results Patients undergoing TightRope suspensionplasty had significantly higher trapeziometacarpal index and thus less subsidence than the LRTI group at 2 weeks (0.22 vs 0.17 [ P < .0001]) and 3 months (0.17 vs 0.15 [ P < .05]) postoperatively. TightRope suspensionplasty also had a significantly lower QuickDASH score at 2 weeks (64.7 vs 74.6 [ P < .05]), 3 months (20.7 vs 32.5 [ P < .05]), and 1 year postoperatively (7.57 vs 21.5 [ P < .05]) compared with the LRTI group. However, there was no difference in VAS pain, lateral pinch strength, reoperation, or complications at any time point between groups. Conclusions Thumb CMC joint arthroplasty performed with a TightRope suspensionplasty versus LRTI yielded short-term improved resistance to subsidence, long-term greater improvement in clinical outcome by QuickDASH, and no difference in pain or complication rates.

Joint injuries and the resulting posttraumatic osteoarthritis (OA) are a significant problem. There is still a need for tools to evaluate joint injuries, their effect on joint mechanics, and the relationship between altered mechanics and OA. Better understanding of injuries and their relationship to OA may aid in the development or refinement of treatment methods. This may be partially achieved by monitoring changes in joint mechanics that are a direct consequence of injury. Techniques such as image-based finite element modeling can provide in vivo joint mechanics data but can also be laborious and computationally expensive. Alternate modeling techniques that can provide similar results in a computationally efficient manner are an attractive prospect. It is likely possible to estimate risk of OA due to injury from surface contact mechanics data alone. The objective of this study was to compare joint contact mechanics from image-based surface contact modeling (SCM) and finite element modeling (FEM) in normal, injured (scapholunate ligament tear), and surgically repaired radiocarpal joints. Since FEM is accepted as the gold standard to evaluate joint contact stresses, our assumption was that results obtained using this method would accurately represent the true value. Magnetic resonance images (MRI) of the normal, injured, and postoperative wrists of three subjects were acquired when relaxed and during functional grasp. Surface and volumetric models of the radiolunate and radioscaphoid articulations were constructed from the relaxed images for SCM and FEM analyses, respectively. Kinematic boundary conditions were acquired from image registration between the relaxed and grasp images. For the SCM technique, a linear contact relationship was used to estimate contact outcomes based on interactions of the rigid articular surfaces in contact. For FEM, a pressure-overclosure relationship was used to estimate outcomes based on deformable body contact interactions. The SCM technique was able to evaluate variations in contact outcomes arising from scapholunate ligament injury and also the effects of surgical repair, with similar accuracy to the FEM gold standard. At least 80% of contact forces, peak contact pressures, mean contact pressures and contact areas from SCM were within 10 N, 0.5 MPa, 0.2 MPa, and 15 mm2, respectively, of the results from FEM, regardless of the state of the wrist. Depending on the application, the MRI-based SCM technique has the potential to provide clinically relevant subject-specific results in a computationally efficient manner compared to FEM.
