Treatment of Scaphoid Non-Unions with Custom-Made 3D-Printed Titanium Partial and Total Scaphoid Prostheses and Scaphoid Interosseous Ligament Reconstruction.

Purpose: Treatment of scaphoid fracture sequelae is still an unsolved problem in hand surgery. Custom-made 3D-printed titanium partial and total scaphoid prosthesis and scaphoid interosseous ligament reconstruction (SLIL) are performed in cases of non-union and isolated aseptic necrosis of the proximal scaphoid pole and when it is impossible to save the scaphoid bone, respectively. This study aims to evaluate the clinical, functional and radiographic results after these two prosthesis implantations.

Total Wrist Arthroplasty with Integra Freedom Implants: A Pilot Study with a New Evaluation System.

Introduction: Recent innovations in wrist arthroplasty implants have led to remarkable improvements in terms of results with improved stability and preservation of bone stock. Despite the advances in such implants, poor outcomes and frequent complications still affect this procedure, not allowing a wider use of this treatment in wrist arthritis.The purpose of this study is to assess the preliminary mid-term results of a Wrist Arthroplasty System (Freedom, Integra Lifesciences, Princeton, USA) in patients with rheumatoid arthritis or secondary osteoarthritis of the wrist and to propose a new classification system.

Short-term findings of a custom-made 3D-printed titanium partial scaphoid prosthesis and scapholunate interosseous ligament reconstruction.

Following wrist trauma due to a karate accident, an 18-year-old male patient developed non-union of the scaphoid with proximal pole necrosis and significant scapholunate gap from an evident scapholunate interosseous ligament (SLIL) injury. A custom-made 3D-printed titanium implant was used for scaphoid replacement and SLIL reconstruction. Good clinical and radiographic outcomes were observed at his 2-year follow-up.

Arthrodesis Versus Arthroplasty in Thumb Carpometacarpal Osteoarthritis: Impact on Maximal Voluntary Force, Endurance, and Accuracy of Pinch.

Purpose: To investigate differences in pinch strength recovery among patients with first carpometacarpal joint osteoarthritis treated with either arthrodesis or suspension arthroplasty.

Methods: Thirty-seven subjects who underwent arthrodesis or suspension arthroplasty for carpometacarpal osteoarthritis were included. Force exerted during maximal voluntary contraction (MVC) in a pinch task was measured.

A case of total scaphoid titanium custom-made 3D-printed prostheses with one-year follow-up.

A 34-year-old male patient developed scaphoid nonunion with necrosis in both fragments. A scaphoid replacement was performed using a titanium custom-made 3D-printed implant. At 1-year follow-up, good clinical and radiographic outcome was obtained.

Reconstructive surgery for thumb osteomyelitis: a new way of remodelling the vascularized medial femoral condyle flap. A case report.

Background: Authors propose a technical innovation for the remodelling of the medial femoral condyle flap (MFCF) for reconstruction of small to medium bone defects performed after the surgical treatment of a thumb osteomyelitis.

Materials And Methods: A 45 year old male had thumb proximal phalanx osteomyelitis after a crush trauma of the dominant right hand and multiple previous unsuccessful surgical attempts in other hospitals. In our centre he underwent to a two stage surgical treatment of the infection through bone and soft tissue reconstruction with a MFCF shaped in a new three dimensional (3D) approach with multiple osteotomies.

Whole-body magnetic resonance imaging in the diagnosis and follow-up of multicentric infantile myofibromatosis: A case report.

Myofibromatosis is an uncommon disorder of infancy, characterized by proliferation of myofibroblasts in solitary or multiple nodules. The clinical characteristics depend on the involved sites: Myofibromatosis may develop as a musculoskeletal form, with non-painful swellings and eventual mass effect symptoms, or as a generalized form with visceral involvement and organ failure. Prognosis and therapy vary between the abovementioned patterns.

Abdomen/pelvis computed tomography in staging of pediatric Hodgkin Lymphoma: is it always necessary?

The purpose of the study was to determine if abdomen/pelvis computed tomography (CT) can be safety omitted in the initial staging of a subgroup of children affected by Hodgkin Lymphoma (HL). Every participating center of A.I.

The total scaphoid titanium arthroplasty: A 15-year experience.

Scaphoid nonunion followed by necrosis of bone segments is a common pathologic condition for the hand surgeon, and the difficulty of its management is well known. The total titanium scaphoid replacement, although not well-described in the literature, in our experience represents a reasonable choice in the treatment of this condition. Strict patient selection is necessary to achieve good clinical results.

Poland syndrome with bilateral features: case description with review of the literature.

Poland syndrome (PS) has been described as unilateral pectoral muscle deficiency variably associated with ipsilateral thoracic and upper limb anomalies. Bilateral hypoplasia/aplasia of the pectoralis muscle and upper limb defects in association with variable thoracic muscles, chest wall deformities and lower limb defects have been infrequently reported in the literature. We report on a 3(1/2)-year-old girl with clinical features consisting in bilateral asymmetric pectoral muscle defects (complete agenesis on the left side and agenesis of the sternocostal head on the right side), nipple hypoplasia, left rib defect, and right hand symbrachydactyly.
