Automated design of bone-preserving, insertable, and shape-matching patient-specific acetabular components.

Effective treatment of large acetabular defects remains among the most challenging aspects of revision total hip arthroplasty (THA), due to the deficiency of healthy bone stock and degradation of the support columns. Generic uncemented components, which are favored in primary THA, are often unsuitable in revision cases, where the bone-implant contact may be insufficient for fixation, without significant reaming of the limited residual bone. This study presents a computational design strategy for automatically generating patient-specific implants that simultaneously maximize the bone-implant contact area, and minimize bone reaming while ensuring insertability.

Microfasciectomy in Dupuytren's disease: microsurgery in the evolution toward safer and more efficient fasciectomy and hand surgery.

In the long term, limited fasciectomy is currently the most reliable treatment for Dupuytren's contracture. The risk for complications is significant, certainly in recurrent disease and in the presence of abundant scar tissue. Meticulous surgical technique is mandatory.

Best practice rehabilitation pathway for the management of single and double-level lumbar fusion surgery: a modified Delphi Study.

Background: There is limited evidence to guide the rehabilitation of patients following single or double-level lumbar fusion surgery (LFS). This is reflected in extensive variability in current rehabilitation regimes and subsequent low clinical success rates, which urges a call for a consensus rehabilitation pathway.

Aim: To establish consensus on the optimal pre-, peri- and postoperative rehabilitation of LFS.

The role of medial ligaments and tibialis posterior in stabilising the medial longitudinal foot arch: a cadaveric gait simulator study.

Background: Debate exists whether adult acquired flatfoot deformity develops secondary to tibialis posterior (TibPost) tendon insufficiency, failure of the ligamentous structures, or a combination of both.

Aim: The aim of this study is to determine the contribution of the different medial ligaments in the development of acquired flatfoot pathology. Also to standardise cadaveric flatfoot models for biomechanical research and orthopaedic training.

The Function Assessment Scale for Spinal Deformity: Validity and Reliability of a New Clinical Scale.

Study Design: Cross-sectional study.

Objective: The aim of this study was to develop and validate the Function Assessment scale for Spinal Deformity (FASD).

Summary Of Background Data: Spinal malalignment impacts daily functioning.

Using a patella reduced technique while balancing a TKA results in restored physiological strain in the collateral ligaments: an ex vivo kinematic analysis.

Introduction: Poor soft tissue balance in total knee arthroplasty (TKA) often results in patient dissatisfaction and reduced joint longevity. Patella-in-place balancing (PIPB) is a novel technique which aims to restore native collateral ligament behavior without collateral ligament release, while restoring post-operative patellar position. This study aimed to assess the effectiveness of this novel technique through a detailed ex vivo biomechanical analysis by comparing post-TKA tibiofemoral kinematics and collateral ligament behavior to the native condition.

Evaluation of tissue displacement and regional strain in the Achilles tendon using quantitative high-frequency ultrasound.

The Achilles tendon has a unique structure-function relationship thanks to its innate hierarchical architecture in combination with the rotational anatomy of the sub-tendons from the triceps surae muscles. Previous research has provided valuable insight in global Achilles tendon mechanics, but limitations with the technique used remain. Furthermore, given the global approach evaluating muscle-tendon junction to insertion, regional differences in tendon mechanical properties might be overlooked.
