Metacarpal joint replacement

Samuel C R Pallapati, Binu Prathap Thomas, George A Anderson
PURPOSE: Benign aggressive expansile osteolytic lesions such as giant cell tumors and aneurysmal bone cysts involving the metacarpal head pose problems in management. Unacceptably high rates of recurrence are reported after curettage and bone grafting. An en bloc excision of such tumors ideally requires osteoarticular replacement of the excised metacarpal heads to retain mobility and function. We used nonvascularized metatarsal head and shaft harvested from the foot to replace the metacarpal defect after en bloc resection to retain movement and function of metacarpophalangeal (MCP) joint...

Several treatment options exist to surgically treat end-stage trapeziometacarpal osteoarthritis. Trapeziectomy is recognized as leading to a mostly acceptable functional outcome. Although rarely encountered, persisting failure of the trapeziectomy is difficult to address. We present a case where several procedures were subsequently performed to treat a failed trapeziectomy condition. First, a trapeziometacarpal prosthesis (Arpe(®), Biomet(®)) was inserted with the two components reversed: the cup in the first metacarpal and the stem in the scaphoid...

PURPOSE: To describe a fibrocartilaginous structure on the dorsal surface of the metacarpophalangeal (MCP) joint. METHODS: A combination of anatomical dissection, histology, ultrasound, and magnetic resonance imaging was undertaken to explore the anatomical structure described, with clinical correlation undertaken by surgical exploration of MCP joints. RESULTS: A dorsal structure of the MCP joint was identified as fibrocartilagenous in composition, triangular in shape, and-together with the volar plate and collateral and accessory collateral ligaments-forming a deepened dorsal fossa in which the metacarpal head invaginated...

In this study, the development of a mechanostatistical model of three-dimensional cortical bone remodelling informed with in vivo equine data is presented. The equine model was chosen as it is highly translational to the human condition due to similar Haversian systems, availability of in vivo bone strain and biomarker data, and furthermore, equine models are recommended by the US Federal Drugs Administration for comparative joint research. The model was derived from micro-computed tomography imaged specimens taken from the equine third metacarpal bone, and the Frost-based 'mechanostat' was informed from both in vivo strain gauges and biomarkers to estimate bone growth rates...

BACKGROUND: Surgery is used to treat persistent pain and dysfunction at the base of the thumb when conservative management, such as splinting, or medical management, such as oral analgesics, is no longer adequate in reducing disability and pain. This is an update of a Cochrane Review first published in 2005. OBJECTIVES: To assess the effects of different surgical techniques for trapeziometacarpal (thumb) osteoarthritis. SEARCH METHODS: We searched the following sources up to 08 August 2013: CENTRAL (The Cochrane Library 2013, Issue 8), MEDLINE (1950 to August 2013), EMBASE (1974 to August 2013), CINAHL (1982 to August 2013), Clinicaltrials...

PURPOSE OF THE STUDY: Arthrodesis of the trapeziometacarpal joint is the method of choice in the treatment of degenerative arthritis of this joint. This procedure was indicated most frequently in middle-age patients doing hard manual labor. Methods for achieving a solid fusion of the trapeziometacarpal joint are known and often reported in the literature. Frequently, they are associated with some failure rate, particularly as concerns bone union. Our study presents a simple and effective method verified in cadaver specimens and then currently used at our department...

Amputation of the thumb causes not only loss of significant functional use of the hand but also psychological and social problems. The procedures of toe-to-thumb transfer, pollicization, or metacarpal extension are recognized and well-documented options in thumb reconstruction. Although these techniques have been successfully applied, they have some disadvantages. This study aims to test the feasibility of the fifth finger for thumb reconstruction. The fifth finger was released following exploration of the digital artery, vein, nerve, and flexor and extensor tendons, including the flexor retinaculum...

BACKGROUND: The intra-articular (IA) application of pulsed radiofrequency (PRF) for pain in small and large joints represents a recent development that has proven to be effective in many cases. We performed a retrospective study of 89 such procedures in 57 consecutive patients with chronic articular pain. OBJECTIVES: The aim of this retrospective study is to evaluate the effectiveness of intraarticular PRF in a group of 57 consecutive patients with chronic joint pain...

Trapezium components from two uncemented total joint replacements were compared in a three-dimensional finite element model. A 100 N axial and angular load was applied in a normal and an osteoporotic bone model. The axial deformation and maximum periprosthetic stress are greater for the Elektra than the Motec CMC cup. The Motec CMC design is less sensitive to changing bone quality. The Elektra cup transmits more stress to the cortical bone rim in all load conditions, but under angular loading the proportionate increase in stress is lower...

Trapezium prosthetic arthroplasty has been utilized to treat basal joint arthritis for nearly five decades in an attempt to mitigate some of the potential disadvantages of trapeziectomy while preserving range of motion. Implant arthroplasty seeks to preserve joint biomechanics, avoids metacarpal subsidence, and should provide immediate stability. These benefits may lead to improvements in strength, durability, and a decrease in metacarpophalangeal joint hyperextension which can occur subsequent to metacarpal shortening...

BACKGROUND: Trapeziometacarpal joint osteoarthritis is a painful, disabling condition that primarily affects women who are postmenopausal. Arthroplasty has been performed to treat this condition; however, subluxation has been a problem with all previous implants. We report the results of hemiarthroplasty using a prosthesis designed to address the problems associated with previous implants. QUESTIONS/PURPOSES: We wished to (1) determine if this prosthesis results in pain relief and functional improvement and preserves the appearance of the thumb, (2) assess the prosthetic reconstruction during followup, (3) assess complications that occur with the use of this prosthesis, and (4) determine the survivorship of this prosthesis...

BACKGROUNDS: The main complication of trapeziometacarpal replacement is trapezial cup loosening due to an imperfect positioning of the trapezial component. This problem is quite similar to those related to other arthroplasties. Hip surgery was progressed toward computer-assisted surgery (CAS) for the improvement of acetabular cup positioning. In this study, we propose an analysis of the feasibility of CAS in trapeziometacarpal replacement. METHODS: We implanted the hand of a cadaver with a trapeziometacarpal prosthesis (Elektra, by SBI)...

Radical resection of the entire ring finger metacarpal for a giant cell tumor resulted in a bony defect extending from the distal surface of the hamate to the proximal surface of the proximal phalanx. We reconstructed the metacarpal with a custom-contoured free fibular osteocutaneous flap and maintained motion at the new fibulophalangeal joint using a silicone arthroplasty. At 4.5 years postoperatively, the patient has shown no signs of recurrence of the giant cell tumor. The silicone arthroplasty has maintained 15° to 85° of motion at the new joint...

Trapezio-metacarpal joint arthritis is common, affecting 7% of men and 15% of women. Numerous surgical techniques are described for this condition but it is not clear which is best. Eighty-six silicone trapezium replacements were assessed at an average of 46 months (six to 156 months) postoperatively for patient satisfaction, pain, key and power grip strength, range of motion, complications and disability with DASH score. Patient satisfaction was 92%. There was excellent pain reduction from 4.2 to 0.6 on a scale of 0 to 5...
