We performed a systematic review to compare outcomes of cemented versus uncemented trapezio-metacarpal joint (TMCJ) replacement for treatment of base-of-thumb arthritis.

We assessed improvements in pain and function, range of movement (ROM), strength, complications and need for revision surgery. A thorough literature search was performed. A total of 481 studies were identified from the literature search (179 Medline, 253 Embase, 27 CINAHL, 22 Cochrane). Of 43 relevant titles 28 were selected for full-text review after assessment of the abstracts. Duplicate studies were removed. 18 studies met inclusion criteria on full-text review. All studies were of level IV evidence. There were no randomised controlled trials or meta-analyses. The studies were critically appraised using a validated scoring system.

Most studies reported good outcomes for pain and strength, and functional outcome was comparable for both groups. ROM was generally improved for both prosthetic types, however statistical calculation was lacking in many studies. Trapezial component loosening was the main problem for both cemented and uncemented prostheses, however radiological loosening did not necessarily correlate with implant failure.

This systematic review has found that both cemented and uncemented replacements generally give good outcomes for the treatment of TMCJ arthritis, however young, male, patients with manual occupations and with disease in the dominant hand and patients with poor trapezial bone stock appear to be at higher risk for implant failure due to cup loosening. We recommend the construction of a joint registry to record implantation and revision rates.

Introduction

Lesser toe proximal interphalangeal joint arthrodesis is a common forefoot procedure for correction of claw toe deformities. The most common method of fixation is with k-wires. Although this is a very cost-effective method of fixation, well-known disadvantages include pin site infection, non union, wire migration and the inconvenience to the patients of percutaneous wires for up to six weeks. For these reasons, intramedullary devices for joint fixation without crossing the distal IP joint have been developed. Many different designs are currently available. The Smart Toe prosthesis which has appeared as a type I and II, is one such implant. In two recent studies using type I, the use of this implant is advocated. We wish to present our experience with the use of the Smart Toe II.

Methods

In this retrospective study we present a radiological review of 46 consecutive cases in 25 patients who underwent lesser toe interphalangeal arthrodeses using the Smart Toe II implant between July 2010 and November 2014 by the senior author. There were 7 (28%) male and 18 (72%) female patients. Post operative radiographs, taken at a mean follow up of 6 months, were reviewed for non-union, migration and implant failure.
