A 2-free-end flexor carpi radialis tendon graft for treating a complex index finger extensor tendon injury.

BACKGROUND: Volar plating has increasingly become the most used technique for the treatment of unstable distal radius fractures due to the low soft-tissue disturbance and its biomechanical reliability, which allows the early mobilization of the wrist. One of the main goals of the volar locking compression plates design is to avoid those soft tissue complications historically associated to the dorsal plating. However, extensor tendon complications can not be completely excluded. METHOD: The authors report the case of a patient with a complete rupture of the index finger extensor tendons after volar plate fixation of the distal radius. Due to the presence of a severe tendons retraction with a 4-centimeter gap and the neighbouring soft tissues damage, it was decided to fill the gap with a 2-free-end autograft harvested from the Flexor Carpi Radialis (FCR) tendon, using the volar surgical approach performed to remove the plate. RESULTS: At the 2-month follow-up, the patient showed the complete recovery of the flexion-extension movements. CONCLUSIONS: Even though the 2-free-end FCR tendon graft is not commonly reported for the reconstruction of extensor tendons defects, we assume it deserves to be considered as an adequate technique whenever the neighbouring tendons are critically compromised.

Injury of the brachial artery accompanying simple closed elbow dislocation: a case report.

BACKGROUND: Elbow dislocation is the second common dislocation in adults, after the shoulder. The anatomical proximity to the joint of the brachial artery could lead to concomitant vascular injuries, even if their occurrence remains very rare. METHOD: It is reported the case of a right-hand-dominant  42-year-old man who sustained a simple closed  posterior elbow dislocation of  his left elbow, associated to a complete brachial artery rupture. He urgently underwent the reduction of the joint dislocation and an artery-repairing surgical procedure using a graft from ipsilateral saphenous vein. RESULTS: The full functional capacity of the elbow was obtained. CONCLUSIONS: The abundance of the brachial artery collateral network may hide the presence of a vascular injury,  potentially associated to a closed elbow dislocation. Therefore, a high index of suspicious should be maintained. The Emergency Team plays a crucial role in its early diagnosis, which is essential to avoid irreversible ischemia related damages. A prompt reduction of the joint dislocation and the vascular injury surgical repair are required. Regarding the treatment of the concomitant collateral ligaments and capsular injuries, the indication to proceed to the simultaneous ligaments reconstruction is still controversial in literature.

Ceramic on ceramic total hip arthroplasty and liner fracture. Two case reports and review of literature.

BACKGROUND AND AIM OF THE WORK: Ceramic on ceramic bearing surfaces in total hip arthroplasty are rising in number with the purpose of reducing debris osteolysis in young patients. New generation ceramics drastically reduced the well known problem of liner's fracture associated with this material but this still represents a complication. METHODS: We present the only two cases of acetabular liner fracture we had in our department, on a total of 252 patients, since we use CoC bearing surfaces in THR (2005-2019) analyzing symptoms and causes of this complication. Review of recent literature focused on symptoms and causes of liners fracture, well matched our cases. RESULTS: In line with the analysis of literature, the major cause of liner fracture is neck-cup impingement resulting in the "edge-loading" effect, followed by other factors like prosthesis design, traumas and patient weight. From data also emerge the role of acoustic phenomena (e.g. squeaking) and CT scan in the diagnostic process. CONCLUSIONS: Last generation ceramics should be used in CoC THR, implant malposition and prosthesis design have a dominant role in liner fracture, squeaking should always be investigated. CT scan have an important role in diagnosis. Implant revision with substitution of the bearing surfaces is mandatory in case of fracture or impending fracture signs.
