We report a new proximal to distal screw fixation technique for proximal pole fractures and non unions of the carpal scaphoid (type I of the Schernberg, Elzein and Gerard classification). Seven cases of non union with a live proximal polar fragment were operated from 1984 to 1986 with 4 excellent and 2 fair results and one failure. Three recent displaced fractures were also treated this way, with 3 excellent results. This useful technique is worth knowing and deserves a place in the treatment of scaphoid fractures, especially type I proximal pole fractures which represent a challenging problem, and are in no way comparable to other locations.

Introduction: Costochondral grafting is well-known reconstructive option for the temporomandibular joint. In the upper extremity, non-vascularized costochondral grafts have been used for radial head reconstruction, for osteoarthritis of the trapeziometacarpal joint and proximal pole reconstruction of the scaphoid. Evidence suggests that vascularization of bone grafts lead to a higher union rate and a faster time to union.

Small proximal pole scaphoid nonunions are challenging to treat. We describe a technique for replacing the proximal pole fragment with an osteochondral autograft transplant harvested from the ipsilateral femoral trochlea. This is indicated in nonunions where the proximal pole fragment is smaller than the scaphoid isthmus; the scapholunate ligament complex is intact on the distal fragment, and in nonunions without dorsal intercalated segment instability and radiocarpal arthritis.

Various reconstructive surgical approaches have been introduced, but each one has some limitations, including microvascular anastomosis, donor site morbidities, and the risk of compromising the scapholunate ligament.
Methods: This prospective interventional case series was performed on five patients.

In clinical situations of complete rehabilitation with fixed prostheses, mastering each parameter of all restorations (shape, marginal adaptation, proximal and occlusal contacts) proves to be a challenge. The large number of restorations involves many potential adjustments that are time-consuming and lead to final ceramic properties degradation. This clinical report highlights the benefits of using castable patterns in complete fixed prosthetic rehabilitation.

Introduction: Some endourological surgeries require multiple screens to perform combined procedures, which can present ergonomic challenges (1, 2). Apple Vision Pro (AVP) is a spatial computing device developed by Apple that incorporates virtual reality (VR) for life-like simulations, realistic medical scenarios, interactive anatomical models, and augmented reality (AR) technologies (3). In health care, VR is used for pain management, physical therapy, psychological therapy, and surgical simulations, providing a controlled and safe environment for both patients and healthcare professionals (4).
