[Intramedullary pinning of the radius in acute Galeazzi's fractures in adults: 23 case reports]

[Retrospective study of Galeazzi fractures in adults hospitalized in the Department of Orthopaedics at the Habib Bourguiba University Hospital, Sfax, Tunisia: about 45 cases]

Galeazzi fracture is defined as the association of radius fracture and inferior radioulnar joint dislocation. Its diagnosis is often unrecognized initially. The purpose of our study is to determine the epidemioclinical features of Galeazzi fracture-dislocations in adults and to assess the functional and radiological outcomes of our case series. We conducted a retrospective descriptive study of 45 patients with Galeazzi fractures treated surgically whose data were collected in the Department of Orthopaedics at the Habib Bourguiba University Hospital, Sfax, Tunisia, over a period ranging from 2009 to 2018. We used Mestdagh score for the clinical evaluation of the results. The mean time between fracture and treatment initiation was 5.35 days. Fixation of the radius was performed using screwed plate in 39 cases and fixation of the radio-ulnar joint using a plug in 13 cases. The average time for union was 10.5 weeks. Outcomes were excellent in 35 patients, good in 3 patients, medium in 6 patients and adverse in a patient. We had 3 cases of sepsis at the level of the plug and two cases of malunions. Galeazzi fracture-dislocation is an under diagnosed disorder in some cases. Dynamic intraoperative examination after solid fixation of the radius can allow for good functional results.

[Functional reconstruction of the forearm by composite free flap of fibula and soleus reinnervated. About a clinical case]

SUBJECT

We present the case of a forearm functional reconstruction of composite fibula free flap. This is a complex forearm trauma by crushing in a 24-year-old patient. The assessment of the lesions showed a bone defect of 15cm radial and ulnar diaphysis, a muscular defect of the posterior compartment of the forearm and a large skin defect next. The radial pedicle was also injured.

METHODS

At 48hours, we conducted a reconstruction by free fibular flap and soleus muscle. The fibula osteosynthesys was performed between the proximal ulna and radius distally. The nerve of the soleus muscle was anastomosed to a branch of the posterior interosseous nerve and tendons of the extensor muscles of the wrist and fingers were sutured to the distal portion of the transferred muscle.

RESULTS

At 6 months, bone healing is achieved. Soleus muscle contracts and the strength of the extensor muscles of the fingers and wrist has been listed 4. Joint amplitudes of -20°/75° for the wrist, complete for the long fingers and the elbow. The aftermath of the donor site is minimal.

CONCLUSION

Reconstruction by free fibular flap and reinnervated soleus muscle is often cited in the literature but few cases are described. It is for us, the best therapeutic solution for this type of injury. It restores muscle function satisfactorily all ensuring high quality coverage defect of the forearm.

[Surgical treatment of Galeazzi fractures in adults by compression plate: about 28 cases]

La fracture de Galeazzi associe une fracture diaphysaire du radius ou des deux os de l'avant bras à une luxation de l'articulation radio ulnaire distale. Décrite en 1934, sa fréquence varie chez l'adulte entre 2,7% et 6,8% de l'ensemble des fractures de l'avant bras. Le traitement admis de façon consensuel chez l'adulte est chirurgical reposant sur une ostéosynthèse stable par une plaque vissée de compression dynamique associée ou non à un embrochage de la radio ulnaire distale. Nous rapportons dans notre étude les résultats cliniques de 28 patients colligés au service de traumatologie et orthopédie A du CHU Hassan II de Fès sur une période de 06 ans. L’âge moyen de nos patients était de 30 ans avec prédominance masculine de 90%; tous nos patients ont présenté un traumatisme de poignet lors d'un accident de sport. Le côté droit était atteint dans 75% des cas. Le bilan radiologique objectiva une fracture diaphysaire du raduis associée à une luxation radio ulnaire distale; nous avons adopté la classification de de Mansat. Le traitement a consisté en une synthèse par une plaque vissée dynamique associée à un embrochage transversal chez six patients qui ont présenté une instabilité de la radio ulnaire distale. L'immobilisation par attelle plâtrée postérieure BABP était de mise. Après un recul de 36 mois, nos résultats ont été très satisfaisants suivant le score de Mestdagh, avec bonne récupération de la mobilité du poignet et reprise de toute activité sportive.
