[Surgical treatment of palmar carpometacarpal dislocation: report of a case]

Les luxations carpo-métacarpiennes sont des lésions rares, les auteurs rapportent un cas de luxation carpo-métacarpienne palmaire du cinquième doigt, traité en urgence par réduction et stabilisation par embrochage à foyer fermé. Une immobilisation postopératoire par une attelle intrinsèque plus a été réalisée pendant six semaines, avec une rééducation à partir de la quatrième semaine. Le résultat fonctionnel était satisfaisant.

[Volar dislocation of four ulnar metacarpals: one case report]

We report a case of volar dislocation of four ulnar carpometacarpals. It's a very rare injury, especially as it affects all long fingers, it is volar and has no fractures. The treatment consisted in open-reduction with pinning carpometacarpal according to intraoperative stability. No complications was noted. The follow-up was a radiological evaluation (pain, strength, mobility) between 6th week and 6th month. The recovery was complete at 6 months without pain. We believe that open reduction allows carpometacarpal osteosynthesis to be the less invasive as possible, depending on the stability visualized and thus can reduce stiffness and residual pain.

[Intramedullary stabilisation of hematometacarpal fracture-dislocation. A case report]

We report a case of a dorsal coronal fracture of the hamate associated with an unstable hematometacarpal dislocation in a 15 year old patient. An accurate assessment was done only after a 3D-CT was performed. Open reduction and intramedullary fixation yielded a very good result.

La luxation carpométacarpienne antérieure complète des doigts. À propos d'un cas

Anterior carpometacarpal dislocation are rare injuries. The anterior type is exceptional. Mr A.T 18 years old, male, student, right-handed, without pathological medical history. He was admitted in emergency after a fall of a motorbike (unknown mechanism) for a closed left hand injury; examination revealed a total impaired mobility and an important swelling of the hand without vasculonervous disorders. X-ray revealed a pure anterior dislocation of the five carpometacarpal joints. The patient was operated on in emergency using both anterior and posterior approach, which allowed to reduce the dislocation. It was maintained by K-wires. An antebrachiopalmar cast was applied for six weeks. One year later, the result obtained was considered excellent.
