Abstract:Background:We compared the clinical results of a newly modified abductor pollicis longus (APL) suspension arthroplasty with trapeziectomy procedure (modified Thompson procedure) with those of the original APL suspension arthroplasty with trapeziectomy procedure (original Thompson procedure) for treatment of advanced osteoarthritis of the thumb carpometacarpal (CMC) joint and assessed the effectiveness of the modified Thompson procedure for thumb CMC osteoarthritis.Methods: Ten hands of 10 patients (Group 1) we… Show more
“…Pain relief post-surgery was reported through multiple methods. Of note, 4 of these articles reported pain by using a visual analogue scale, ranging from 0 representing 'no pain' and indicating 'worst pain' 9,[24][25][26] . Out of the 159 patients these studies investigated, the authors report an overall improvement in pain levels from 7.47 to 1.9 9,24,26 ; whilst Earp et al 25 reported 0 post-op (no retrospective pre-op VAS available).…”
Background:The prevalence of osteoarthritis (OA) of the first carpometacarpal (CMC) joint and subsequent thumb disability is rising. Abductor pollicis longus tendon interposition arthroplasty (APLTIA) has gained popularity as a procedure to alleviate pain and restore thumb function.
Methods:A systematic review was performed to assess the current reported outcomes of APLTIA. Inclusion criteria involved clinical studies with caseseries 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.Results: 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. APLTIA was not found to complicate further surgery.
Conclusion: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.

“…Nanno et al investigated the clinical results of 16 patients who were treated with a modified Thompson procedure with a mean follow-up of 25 months. The VAS score markedly improved from 8.64 to 1.2 [ 9 , 21 ]. Rab et al focused on the long-term results of 20 patients who underwent APL suspension arthroplasty similar to the Lundborg method with a mean follow-up of 23.1 months.…”

“…Nanno et al evaluated the average radial and palmar abduction with 30.9° and 36.5° before surgery and 54.1° and 48.9° after surgery. The radial abduction after surgery was significantly better than before surgery [ 21 ]. In the study by Rab et al, the ROM of radial abduction after arthroplasty was 63.4° ± 14.3° versus 60.3° ± 12.7° for palmar abduction [ 22 ].…”

Nanno et al showed that average pinch tip and grip strength markedly improved from 3.43 kg and 13.3 kg before surgery to 4.61 kg and 18.8 kg after surgery [ 21 ].

Purpose
The primary treatment goals for advanced-stage thumb carpometacarpal (CMC) joint osteoarthritis are complete pain relief and restoration of thumb strength. The purpose of the present study was to introduce a variation of the abductor pollicis longus (APL) suspension arthroplasty using a single looping of a radial slip from the APL tendon around the flexor carpi radialis (FCR) tendon combined with RegJoint™ interposition and to determine its efficacy in the treatment of thumb CMC joint osteoarthritis.
Methods
Between 2015 and 2017, 21 patients were included. The average age was 60.8 years (range 48–79). The mean follow-up was 27.7 months (range 8–50). Evaluation included pain, radial and palmar abduction, tip pinch and grip strength, and Disabilities of the Arm, Shoulder, and Hand (DASH) score.
Results
Pain averaged 0.3 (range 0–4) at rest and 1.4 (range 0–4) on exertion. The radial and palmar abduction were 97% and 99% compared to the contralateral side. The tip pinch and grip strength were 4.1 kg (range 3–6.5) and 22 kg (range 13.3–40), respectively. The DASH score accounted for 18.5 (range 0.8–41.7).
Conclusion
The modified APL suspension interposition arthroplasty was an efficient and simplified option for the treatment of thumb CMC joint osteoarthritis, with results comparable or better than other published procedures. The APL suspension technique was easy to perform avoiding difficult bone tunneling and incision of the FCR tendon. The RegJoint™ interposition as spacer prevented impingement of the first metacarpal base on the second metacarpal base or the trapezoid bone.
Methods:
An institutional review board–approved retrospective review of patients who underwent trapeziectomy and ligament reconstruction and tendon interposition (LRTI) was conducted. Patient demographics, visual analogue scale pain scores, grip strength, pinch strengths, and radial and palmar abduction were collected. The trapezial space ratio (TSR) was measured by the scaphometacarpal distance divided by the length of the capitate. Subsidence [(postoperative TSR − preoperative TSR)/preoperative TSR] was measured and classified as severe (≥70%) or mild to moderate (<70%). Median rate of subsidence increase was calculated. Conolly-Rath scores were used to evaluate the proportion of good outcomes in each group.
Results:
A total of 141 trapeziectomies with LRTI were included. Subsidence increased 6.7% (5.4% to 23.0%) per week before 16 weeks and 0.3% (0.1% to 0.8%) per week thereafter. Visual analogue scale pain scores were not significantly different between patients with severe or mild to moderate subsidence (P = 0.25) 16 weeks after thumb mobilization. The proportion of good outcomes was comparable between the two groups (P = 0.12). There was no correlation between subsidence and pain (ρ = −0.20; P = 0.24), grip (ρ = −0.02; P = 0.93), key (ρ = −0.13; P = 0.62), tripod (ρ = 0.16; P = 0.71), or index tip pinch strengths (ρ = −0.28; P = 0.43) or radial (ρ = −0.03; P = 0.92) or palmar (ρ = −0.15; P = 0.61) abduction.
Conclusions:
Subsidence occurs in all patients after trapeziectomy and LRTI, stabilizing 16 weeks after mobilization. Degree of subsidence does not correlate with postoperative outcomes.
