Abductor pollicis longus tendon interposition arthroplasty (APLTIA) has gained popularity as a procedure to alleviate pain and restore thumb function.</span></span></span><br> <span style="font-size:12pt"><span style="line-height:200%"><span new="" roman="" style="font-family:" times=""><b>Methods:</b> A systematic review was performed to assess the current reported outcomes of APLTIA. Inclusion criteria involved clinical studies with case-series as the minimal accepted level of evidence. Our primary outcome focussed on PROMs data, whilst secondary outcomes focussed on objective measures of function and complications. Papers investigating pathologies other than CMC OA or procedures other than APLTIA were excluded.</span></span></span><br> <span style="font-size:12pt"><span style="line-height:200%"><span new="" roman="" style="font-family:" times=""><b>Results:</b> Twelve studies were included (485 thumbs), all of which were observational in study design. APLTIA appears to be associated with a reduction in pain and functional improvement. <span style="background:white">APLTIA was not found to complicate further surgery. </span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:200%"><span new="" roman="" style="font-family:" times=""><b><span lang="EN-GB" style="background:white">Conclusion:</span></b> APLTIA may be associated with improvement in short-term pain relief and functional status. Further research is required to evaluate the benefits, duration of relief and long-term outcomes of APLTIA.</span></span></span><br> &nbsp; Systematic review, Trapeziectomy, Abductor Pollicis Longus, Tendon interposition arthroplasty 3 17 http://wjps.ir/browse.php?a_code=A-10-571-4&slc_lang=en&sid=1 Omar Dawood 100319475328460012953 100319475328460012953 No Queen Victoria Hospital, East Grinstead, UK Livyar Mustafa 100319475328460012954 100319475328460012954 No St George’s Hospital Medical School, London, United Kingdom Enas Shuber 100319475328460012955 100319475328460012955 No St George’s Hospital Medical School, London, United Kingdom Ahmed Hagiga 100319475328460012956 100319475328460012956 No Queen Victoria Hospital, East Grinstead, UK Ahmed Hagiga 100319475328460012957 100319475328460012957 No Queen Victoria Hospital, East Grinstead, UK Nicholas Cereceda- Monteoliva 100319475328460012958 100319475328460012958 No Queen Victoria Hospital, East Grinstead, UK Murtaza Kadhum* Murtaza.kadhum@nhs.net 100319475328460012959 100319475328460012959 Yes Queen Victoria Hospital, East Grinstead, UK
