Limb-salvage surgery is the standard care for most malignant tumors affecting the extremities, and a vascularized fibula transfer is probably the most popular microsurgical option to reconstruct long-bone defects. Skeletal reconstruction after bone-tumor resection involving the metepiphysis of a growing child can be successfully achieved with a vascularized fibula graft incorporating the proximal physis and active growth plate. Such a procedure has been utilized in 12 children under the age of 10 years who had malignant bone tumors located in the upper limb (3 in the distal radius, 9 in the proximal humerus). The follow-up ranged between 4 years and 3 months. Ten grafts were supplied by the anterior tibial artery, and two by the peroneal artery. The average growth rate of the grafts based on the former artery has been more than 1 cm per year, ranging between 0.75 and 1.33 cm. The authors describe a modified operative technique and discuss the clinical results of the procedure which offers a satisfactory skeletal reconstruction and prevents future limb-size discrepancy.
Background Fragment-specific fixation of the distal radius is born to fix each articular fragment with limited surgical approach and low-profile devices. Over time, many devices with different designs and characteristics have been developed. However, many of them have showed the inability to securely fix marginal, small, and comminuted fragments as bony ligament avulsions and bony compression injuries.
Purpose The purpose of this study was to evaluate the clinical and radiological outcome of a new device born to treat marginal articular fractures of the distal radius.
Patients and Methods A retrospective review was conducted on 23 patients with a mean follow-up of 21 months including postoperative clinical evaluation, grip strength, computed tomography scan, and X-ray control.
Results All fragments healed and maintained reduced until the final follow-up. The carpus was aligned with the distal radius in all patients presenting with a radiocarpal dislocation.
Conclusion The volar rim fragment is an attachment site for the short radiolunate and the volar distal radioulnar ligament. Its unstable fixation can lead to articular incongruity, volar or dorsal subluxation of the carpus, and distal radioulnar instability. The involvement of this fragment on distal radius fractures is relatively common and many studies of the literature have been focused on its treatment. The Hook Plate stabilizes distal fragments at their bone–ligament interface. In addition to bony reduction, the device permits to stabilize the capsule and ligaments, as volar bony ligament avulsions, in a picture of dorsal radiocarpal dislocation.
Level of Evidence This is a Level IV, case series.
Surgical treatment of extra-articular metacarpal and phalangeal fractures should be considered when there is instability or in patients with high demand. To overcome the issues related to the use of Kirschner wires, external fixators, and open reduction and internal fixation procedures, intramedullary headless screw fixation (IHSF) is an alternative technique to achieve primary fracture stability and early return to daily activities. We report the data of the Italian Multicentric Intra-Medullary Experience, which includes 173 cases of extra-articular unstable fractures (38 phalanges and 135 metacarpals) treated with the IHSF. After surgery, patients underwent early mobilization without splinting. The results confirm the reliability of IHSF in cases with non-articular involvement, showing a good recovery rate in terms of bone healing and range of motion. Level of evidence: IV
