Thumb basal joint arthritis in 2023.

Thumb carpometacarpal or basal joint arthritis is the second most common location for osteoarthritis in the hand. It mainly affects women over 50years of age. Basal joint arthritis causes pain, loss of strength during pinch grips, and eventually stiffness and progressive deformity of the thumb column.

Tenosynovial chondromatosis of the wrist: A case report.

We report the case of an 80-year-old woman who presented with an asymptomatic slowly growing mass in the dorsal aspect of her right wrist. Radiographs revealed a snail-shaped radiopaque structure. Surgical exploration and excision revealed a calcified lesion over the extensor digitorum communis.

COVID-19: Initial experience of an international group of hand surgeons.

The emergence of the COVID-19 pandemic has severely affected medical treatment protocols throughout the world. While the pandemic does not affect hand surgeons at first glance, they have a role to play. The purpose of this study was to describe the different measures that have been put in place in response to the COVID-19 pandemic by hand surgeons throughout the world.

The Moovis® implant for trapeziometacarpal osteoarthritis: results after 2 to 6 years.

In this retrospective study we reviewed the outcomes of 46 trapeziometacarpal joint replacements with the Moovis® prosthesis in 46 patients with painful osteoarthritis. The dual mobility design of this prosthesis aims to reduce prosthetic dislocation and subsidence. At follow-up 2 to 6 years (mean 5 years) after operation, pain was reduced from 6 to 0 on a visual analogue scale from 0 to 10.

Surgical Fixation of Metacarpophalangeal Collateral Ligament Rupture of the Fingers.

Background: Collateral ligament injury of the metacarpophalangeal joint of the fingers is underreported in the literature and widely underestimated by the medical community. Here, the authors present results from a large series of patients and review factors influencing success of surgery.

Methods: The authors performed a retrospective study of 46 patients who underwent surgical fixation of the metacarpophalangeal collateral ligament using bone anchor in an acute or chronic setting.

Strickland's hypothenar fat pad flap for revision surgery in carpal tunnel syndrome: Prospective study of 34 cases.

Several techniques are available for revision surgery of carpal tunnel syndrome (CTS) to preserve a gliding layer and protect the median nerve, including Strickland's pedicled hypothenar fat pad flap. The objective of this single-center, prospective study was to report the results of this flap after a minimum follow-up of two years. Between March 2006 and April 2014, 34 patients were enrolled (mean age 67 years) who had postoperative complications after the primary surgical release of CTS with nighttime paresthesia and/or neuropathic pain and abnormal electromyography findings.

Trapeziectomy and ligament reconstruction tendon interposition after failed trapeziometacarpal joint replacement.

Total trapeziometacarpal (TMC) joint replacement is increasingly being performed for the treatment of basal joint arthritis. However, complications such as instability or loosening are also frequent with TMC ball-and-socket joint replacement. Management of these complications lacks consensus.

[Anterior transolecranon fracture-dislocations of the elbow in children: A case report and review of the literature].

Anterior transolecranon fracture-dislocations of the elbow are rare in children and the literature is poor in recommendations for the management of these lesions. We report a new case with a type of lesion that has not been described previously and discuss this pathology. Based on a literature review, we propose a classification into four types of anterior transolecranon fracture-dislocations of the elbow in children, thereby guiding surgical indications.

Comparison of the anatomical dimensions and mechanical properties of the dorsoradial and anterior oblique ligaments of the trapeziometacarpal joint.

Purpose: The respective roles of the dorsoradial (DRL) and anterior oblique (AOL) ligaments in stability of the highly mobile trapeziometacarpal (TMC) joint remain disputed. Earlier publications have pointed to the AOL as the key stabilizing structure; yet, more recent publications have challenged the stabilizing role of the AOL, favoring the DRL as the main TMC joint stabilizer. We executed an anatomical study of the ligaments, including detailed dissection to quantify the length, width, and thickness of the AOL and DRL and tested the material properties of these ligaments.

[The modified Lamberty and Cormack's flap for neuropathies of the ulnar nerve at the elbow].

Surgical treatment of ulnar nerve syndrome at the elbow gives good results in the majority of cases but there are sometimes incomplete results or recurrences that can lead to iterative procedures. This iterative surgery is responsible for painful neurological sequelae often resistant to pharmacological treatments. In these selected resistant cases, we made the choice of a surgical treatment associating a neurolysis of the ulnar nerve and wrapping with a vascularized flap modified from Lamberty and Cormack.

Resection of the flexor digitorum superficialis for trigger finger with proximal interphalangeal joint positional contracture.

Purpose: Open release of the A1 pulley is a widely known procedure for the treatment of trigger finger. A subset of patients presents with both trigger finger and a positional contracture of the proximal interphalangeal (PIP) joint. These patients usually have a long history of trigger finger or have already undergone a surgical release of the annular pulley.

[Continuous infusion of ropivacaine has no effects on pyrolytic implant: a preliminary study in rats].

The aim of the study is to analyse the effects of ropivacaïne on a pyrolytic implant in bone surgery. Ten rats were operated with a pyrolytic implant placed at the hip after femoral head resection: five cases with continuous infusion of ropivacaïne and five cases with continuous infusion of sterile water. Six days after, all the implants were analysed: weight, length, width, thickness and global design.

[Spontaneous rupture of extensor pollicis longus in isolated trapeziometacarpal arthritis].

A spontaneous rupture of the extensor pollicis longus (EPL) tendon occurred in a patient with trapeziometacarpal arthritis. We hypothesize that a mechanical attrition by protrusion at the trapeziometacarpal joint alone was responsible of a spontaneous rupture of the extensor pollicis longus tendon.

[Short term results of total carpometacarpal joint replacement surgery using the ARPE implant for primary ostearthritis of the thumb].

Introduction: We have reviewed the short-term results of the ARPE arthroplasty of the first carpometacarpal joint for osteoarthritis of the thumb.

Material And Methods: One hundred and eighteen patients have been operated on in our department between June 1999 and June 2003, by the same surgeon. Sixty-three of these patients had been followed for a minimum of six months and were included in this retrospective study.

Could this unusual scaphoid fracture occurring in a badminton player be a stress fracture?

An unusual fracture of the scaphoid occurred in an otherwise healthy young badminton player, caused by a violent movement of extension/flexion of the wrist while performing a smash. There was no direct blow or fall on the wrist, nor history of wrist pain prior to the fracture. No underlying pathology was identified.

Giant cell tumours of the tendon sheath: lack of correlation between nm23-H1 expression and recurrence.

Some authors attribute recurrences of giant cell tumours to biological factors which are only expressed in some tumours. Grover et al. (1998) suggested that the risk for recurrence is associated with the down-regulation of the nm23-H1 gene.

Reducing patient discomfort during digital blockade: The subcutaneous single injection digital block - A simple, safe and fast procedure.

Background: Regional anesthesia of a single finger is commonly achieved by the traditional ring block, which requires at least two painful injections in the digit. Single injection digital block techniques have been described to avoid this problem. Among these, the subcutaneous technique described by Harbison appears to be safe and to allow most procedures to be carried out with good tolerance.

Percutaneous Herbert screw fixation for fractures of the scaphoid: review of 30 cases.

Introduction: The purpose of this study was to evaluate the results of percutaneous fixation of undisplaced or minimally displaced fractures of the scaphoid using the first generation Herbert screw in terms of union, functional results and scaphoid mobility.

Methods: 30 of the 50 patients operated on in our department between 1995 and 2000 were available for evaluation by an independent observer. Wrist mobility, grip strength and key pinch were measured.

Single injection digital block: comparison between three techniques.

Introduction: Regional anesthesia of a single finger is commonly achieved by the traditional ring block. The major drawback of this technique is the need for at least two painful injections in the digit. Single injection techniques have been described.

Atypical mycobacterial infections of the hand: report of eight cases and literature review.

Introduction: Atypical mycobacteria are an uncommon cause of hand infections in immunocompetent patients. Diagnosis is often delayed, with consequent increased morbidity. Better awareness would allow earlier diagnosis and treatment.

Modifications to the mechanical behavior of the wrist after fracture of the scaphoid. Modeling by finite element analysis.

Although based on their long-term clinical evolution there appeared to be no doubt that fractures of the scaphoid modify the mechanical behavior of the carpus, the mechanisms of these modifications have not yet been investigated. This study based on finite element analysis provides insight into the sequence behind the onset of arthritis of the wrist, highlighting the existence of pressure peaks at the nonunion and at the midcarpal interface (scaphoid-capitate and lunate-capitate). This evidence explains the clinical evolution of nonunions of the scaphoid.

[Vascularized surgical rotation of a bi-articular trapezoid-trapeziometacarpal complex for the treatment of severe rhizarthrosis of the thumb].

Unlabelled: A new surgical procedure has been conceived to avoid persistent pain and to restore the functionality and pinch strength of the basal joint of the thumb destroyed by degenerative osteoarthritis. Since January 1998 a double total joint transposition was performed on eight patients, switching the trapezoid-metacarpal joint and the trapezio-metacarpal joint. A 180 degrees rotation of the bi-articular complex (trapezoid-trapezio-metacarpal joints) in its entirety was achieved, while preserving the intrinsic ligaments and vascular supply insured by the dorsal branch of the radial artery; the Cardan conformation in Physics of the trapezoid-metacarpal joint provided complete thumb motion.

[Failure of total uncemented trapeziometacarpal prosthesis. A multicenter study].

The total trapeziometacarpal prosthesis that we have designed has been used clinically for five years. We thought it would be useful to revise failures of these prostheses in a multicentre study in order to identify the causes of the problems and to provide necessary modifications for improvement of the results. Eleven surgeons participated in this study, allowing the review of 24 failures out of a total of 188 implanted prosthesis (12.

Excision of the trapezium for osteoarthritis of the trapeziometacarpal joint of the thumb.

We assessed the results of 86 trapeziectomies in 83 patients. Simple excision of the trapezium was performed in 54 thumbs. This was combined with shortening of the abductor pollicis longus tendon in 14 thumbs and with soft-tissue interposition and/or ligamentous reconstruction in 17 thumbs.

[Percutaneous Herbert screw osteosynthesis of the scaphoid bone].

Scaphoid fractures are the most common carpal fractures. Conservative treatment is long, and non-union is frequent after immobilization in a cast. The Herbert procedure is an improvement, but access to the scaphoid is through an extensive open exposure that damages the blood vessels and the anterior radiocarpal ligaments.
