Metal hypersensitivity in trapeziometacarpal arthroplasty: A systematic pattern of progression.

Metal hypersensitivity is a rare and often underestimated complication, as shown by the small number of published studies, particularly concerning the upper limbs and the hand. However, the increase in the annual number of trapeziometacarpal arthroplasties underlines the importance of better understanding of this problem. We performed a study based on data from the revision of trapeziometacarpal prostheses to assess the incidence of this complication and to define a sequence of radiological changes to detect metal hypersensitivity.

Egg membrane as a training model for microsurgery.

Teaching microsurgery is limited by the availability of appropriate training models. In-vivo models, such as rats, remain the gold standard, but ethical and economic limitations restrict their use for initial training. This study investigated the feasibility of using egg membrane as an inert model, an accessible and economical alternative for introduction to microsurgery.

Surgical treatment of trigger finger: a comparative study of A1 pulley opening versus ulnar superficialis slip resection.

Trigger finger is a common condition. Surgery most frequently involves opening the A0 and A1 pulleys. However, this shows limited effectiveness in correcting proximal interphalangeal joint fixed flexion deformity.

Nail dystrophy for the surgeon.

Injuries to the fingertips are the most frequently occurring damage to the hand. The nail is an exceptional structure within the human body that offers both stability and protection, as well as the ability to perform fine and precise movements. Nail dystrophies are numerous, post-traumatic, post-infection or even degenerative.

Physiology of the nail apparatus: Surgical consequences.

Knowledge of nail physiology is mandatory to understand nail pathologies, and to know what to repair and what to expect from your repair. Unfortunately, nail physiology in humans is not completely understood. However, there are some data that have been validated and must be known before treating patients.

Hook nail deformity.

Hook-nail deformity is frequently seen after a fingertip amputation, whether or not flap reconstruction has been done. It is more frequent if the bony support is missing. The deformity results in esthetic and functional impairment which can lead to complete finger amputation.

Surgical anatomy of the nail.

Knowledge of nail anatomy is a prerequisite for both diagnostic and therapeutic purposes. The nail apparatus is a highly specialized structure, but is in close relationship to the distal phalanx which supports it and to the pulp which carries the sensory receptors and is involved in pinching. It can be divided by the nail plate into the perionychium underneath, and the paronychium above.

Prevalence of transthyretin amyloidosis in patients undergoing carpal tunnel surgery: a prospective cohort study and risk factor analysis.

Transthyretin amyloidosis is a frequent cause of heart failure, resulting from an accumulation of abnormal proteins in the myocardium. Recent research has highlighted the importance of early diagnosis to enhance the effectiveness of specific treatments. Extra-cardiac symptoms may precede several years before cardiac complications, with carpal tunnel syndrome often considered a red flag.

Recurrence of ulnar tunnel syndrome: Long-term clinical and functional results of surgical management using revision neurolysis and subcutaneous anterior transposition.

Objective: Recurrence after primary ulnar tunnel syndrome surgery is observed in 1.4%-25% of patients. However, the outcome of revision surgery is uncertain and limited.

Self-Assessment Versus Peer-Assessment in Microsurgery Learning: A Comparative Retrospective Study in a Surgery Residents Cohort.

Introduction: In surgical learning, self-assessment allows the physician to identify and improve his strong and weak points. However, its scientific validity has yet to be demonstrated. The aim of this study was to analyze if there is a link between self-assessment accuracy and improvement in surgical skills.

Validation of a simplified evaluation grid applied to the microsurgery on inert material via smartphone.

Objectives: Microsurgery is usually performed in experimental research models and clinical surgery. It requires meticulous technical skills and continuous training. Inert materials such as Shirataki noodles are readily available and low-cost consumables regularly used for practice.

Posterolateral stabilization of the elbow by autologous ligament reconstruction to limit long-term development of osteoarthritis.

Background: Posterolateral instability is the most frequent form of both acute and chronic elbow instability. Joint incongruity due to posterolateral unlocking leads to shear and compression stress of the internal aspect of the humeroulnar joint. We carried out long-term analysis of patients with posterolateral elbow instability in order to determine whether, in addition to improving their symptoms, reconstruction of the lateral collateral ligament complex may play a protective role against the development of post-traumatic osteoarthritis.

Treatment of advanced trigger finger by ulnar superficialis slip resection: Long-term outcome and predictive factors for poor prognosis.

The aim of this study was to evaluate the outcome of ulnar superficialis slip resection and to determine predictive factors for poor prognosis in patients with advanced trigger finger. Over a 5-year-period, 55 patients (58 fingers) were included. After surgery, two groups were identified: group 1, with complete extension or <10° extension deficit in the proximal interphalangeal (PIP) joint (n = 27 fingers/27 patients); and group 2, with ≥10° residual PIP extension deficit (n = 31 fingers/28 patients).

Modeling and concepts of the Malingue plasty compared to Z-plasty.

Malingue's diamond-shaped skin plasty is a random skin plasty derived from the Z-plasty. Not widely known, this technique is an alternative to fasciectomy in Dupuytren's disease. The main objective of the present study was to analyze the topographical and anatomical differences between Z-plasty and Malingue plasty in cadaveric and experimental models and the geometrical and mathematical differences in modeling, in order to determine the respective gains in length.

The Arthroscopic Trillat Procedure Is a Valuable and Durable Treatment Option for Recurrent Anterior Instability Associated With Massive Irreparable Cuff Tears.

Purpose: The purpose of the present study is to report the mid- and long-term clinical and radiologic outcomes of the arthroscopic Trillat for the treatment of recurrent anterior instability in patients with chronic massive irreparable rotator cuff tears (MIRCTs) and maintained active shoulder motion where reverse shoulder arthroplasty (RSA) is not indicated.

Methods: Twenty-one consecutive patients (mean age 61 years) were identified and retrospectively reviewed. All patients had recurrent anterior dislocations and conserved active forward elevation and active external rotation.

The Arthroscopic Trillat Procedure Is a Valuable Treatment Option for Recurrent Anterior Instability in Young Athletes With Shoulder Hyperlaxity.

Purpose: The purpose of this study is to report the outcomes of the all-arthroscopic Trillat procedure, combined with capsular plication, for the treatment of recurrent anterior instability in young athletes with shoulder hyperlaxity (external rotation >90°).

Methods: We performed a retrospective evaluation of patients with recurrent anterior instability and shoulder hyperlaxity who underwent an arthroscopic Trillat between 2009 and 2019. Patients with concomitant rotator cuff lesions or voluntary or multidirectional instability were excluded.

Comparison of results of arthroscopic arthrolysis between traumatic and degenerative elbow stiffness.

Introduction: Elbow stiffness significantly affects the patient's quality of life. This joint must have at least 30°/130° extension/flexion and 50°/50° pronation/supination to function normally according to Morrey.

Hypothesis: The objective of this study was to evaluate functional outcome of arthroscopic arthrolysis by comparing stiffness of post-traumatic and degenerative origin.

Acute pain after digital crushing and nicotine intoxication. Cigarettes are always a false friend. A prospective study.
