Indications and functional outcome of the use of integra® dermal regeneration template for the management of traumatic soft tissue defects on dorsal hand, fingers and thumb.
Few studies have been conducted to explore the utility of the Integra® dermal regeneration template (IDRT) combined with a delayed split-thickness skin graft (STSG) for reconstructing complex dorsal hand, digit, and thumb injuries. This study reports the indications and outcomes for 14 patients treated with this technique via a two-stage process. ⋯ The 36-month follow-up demonstrated that IDRT is a safe and reliable technique that can be considered a viable alternative to flap reconstruction for the management of traumatic STDs in selected patients. The aesthetic outcomes are acceptable, functional recovery of the fingers is excellent, patient satisfaction is very high and the rate of complications is very low.

Case ReportsCustom-made wrist prothesis (UNI-2™) in a patient with giant cell tumor of the distal radius: 10-year follow-up.
Wrist endoprosthesis is still an exceptional indication compared to the prosthesis of large joints, especially when a rescue surgery procedure of the wrist is no longer possible and the complete wrist arthrodesis is to be considered the ultima ratio. However, a suspended function in the wrist is accompanied by a significant restriction in the patient`s daily life. Using the fourth-generation endoprosthesis, the situation regarding long-term results for the hand has already improved. ⋯ If autologous reconstructions cannot be performed, custom-made prostheses can be considered as very rare indications for joint reconstruction. While these have been used for years on large joints such as shoulder, elbow, knee and hip, they have only been described on the hand in particular cases. We report the 10-year follow-up of implantation of a custom-made wrist prothesis (UNI-2™, KMI, Germany) in a 36-year-old patient with tumorous destruction of the distal radius by a giant cell tumor.

The effects of kinesiophobia on outcome following total knee replacement: a systematic review.
Kinesiophobia, the fear of physical movement and activity related to injury vulnerability, has been linked to sub-optimal outcomes following total knee replacement (TKR). This systematic review has two aims: to define the relationship between kinesiophobia and functional outcomes, pain and range of motion following TKR, and to evaluate published treatments for kinesiophobia following TKR. ⋯ Kinesiophobia negatively affects functional outcomes up until 1 year post-operatively, while active ROM is reduced up to 6 months post-procedure. Post-operative functional and psychological interventions can improve kinesiophobia following TKR.

Improving radiographic imaging for circular frames: the Cambridge experience.
Limb reconstruction using circular frames requires complex accurate measurements to achieve correction of mechanical bone axis. Inadequate imaging could ultimately lead to poor clinical outcome. Therefore, radiographs should be obtained in a standardised manner to yield accurate results. Our aim is to improve the effectiveness of post-operative imaging by obtaining precise examinations and improving the accuracy of frame correction; therefore, reducing technical repeats, radiation exposure, time waste in clinic, and achieving cost effectiveness. ⋯ We have been able to achieve a significant improvement in the quality of post-operative radiographic imaging and have expanded its use to adult frame patients with a background of traumatic or infectious aetiologies.

Use of porous custom-made cones for meta-diaphyseal bone defects reconstruction in knee revision surgery: a clinical and biomechanical analysis.
Although the practice of metaphyseal reconstruction has obtained successful clinical and radiological results in revision total knee surgery, off-the-shelf devices aren't an effective solution for all patients as they do not cover the full range of clinical possibilities. For this reason, during severe knee revisions, custom-made porous titanium cementless metaphyseal cones are nowadays employed as alternative to traditional surgeries. The aim of this study is to understand the benefits gained by the use of the custom-made cones against the performance of more traditional techniques, such as the use of cemented or cementless stems. Thus, a retrospective study on eleven patients and a biomechanical finite element analysis (FEA) was developed, based upon three clinical cases of the clinical analyzed cohort. ⋯ Based upon the clinical evidence and the findings after the FEAs, the practice of porous custom-made metaphyseal cones in severe revisions of knee arthroplasties is showing promising biomechanical results. The homogeneous stresses distributions and the lower bone stress gradient could justify a reduction of bone fractures and the risk of implant loosening which could be the explanation to the successful clinical outcomes.
