Trapeziometacarpal joint dislocation complicated by a trapezium fracture: A case report and literature review

Association of Acute Trapeziometacarpal Joint Dislocation and Trapezium Fracture in a 14-Year-Old Boy: A Case Report

“…The rarity of this lesion makes it hard to get consensus on the ideal treatment of this complex lesion, mainly because of the controversies existing on the role of stabilizing structures of the TM joint. 1,4…”

“…Its association with a fracture of the trapezium is even more unusual, being reported in literature only as case reports or case series, 3-6 with only 3 cases of young patients aged below 15 years old to our knowledge. 7-9…”

Trapezium Fracture Associated with Thumb Carpometacarpal Joint Dislocation: A Report of Three Cases and Literature Review

“…Given that isolated trapezium fracture and thumb CMC joint dislocation are rare injuries [ 1 , 2 ], the combination is extremely rare, with only 14 cases reported in the English literature [ 3 – 15 ]. Walker et al [ 16 ] classified trapezium fractures into five patterns ( Figure 7 ).…”

“…No consensus exists regarding optimal treatment for this rare injury. In previously reported cases, conservative therapy [ 4 , 5 ], closed reduction with K-wire fixation [ 3 , 6 , 7 ], open reduction with K-wire fixation [ 8 – 10 ], open reduction with internal fixation [ 11 – 13 , 15 ], and closed reduction with external fixation [ 14 ] were performed, and excellent results have been reported ( Table 1 ). Bosmans et al [ 2 ] stipulated that treatment depends on the degree of instability and anatomic restoration after the first reduction.…”

“…Although ligament reconstruction is currently thought to be too aggressive as the primary treatment for this injury [ 2 ], there is no consensus regarding optimal treatment. In the previously reported cases, Mody and Dias [ 8 ] and Roger et al [ 15 ] treated their cases with ligament reconstruction in addition to K-wire or internal fixation, due to obvious intraoperative instability of the CMC joint. In order to avoid long-term complications such as those seen as in the current case 1, we must strictly assess the instability of the joint.…”
