ABSTRACT
A clinical, radiological and four-dimensional computed tomography (4DCT) assessment of the outcomes of scapholunate intercarpal ligamentoplasty (SLICL) was done with a minimum follow-up of 2 years. Twenty-nine patients (23 men and 6 women) with a mean age of 40 years (22-57) who had chronic scapholunate dissociation were treated with the SLICL procedure. There were 18 cases of dynamic instability and 11 of static instability. The patients were evaluated with a mean follow-up of 61 months (24-94). SLICL significantly reduced pain and increased grip strength and wrist function. On radiographs, the mean static and dynamic scapholunate gaps as well as the scapholunate and radiolunate angles improved significantly. The dorsal scaphoid displacement was always corrected. 4DCT after surgery provided a more precise analysis of the SLICL's effectiveness at restoring intracarpal alignment. Correction of the DISI deformity and dorsal scaphoid displacement was confirmed. SLICL restored a normal variation in the scapholunate gap (range value) during radioulnar deviation movement without systematically reducing the distance between the bones (mean and maximum values) which remained pathological in wrists with static instability but not in those with dynamic instability. At the final follow-up, no patients had signs of osteoarthritis due to ScaphoLunate Advanced Collapse. LEVEL OF EVIDENCE: III.
ABSTRACT
INTRODUCTION: Scaphotrapeziotrapezoid (STT) arthrodesis and Pyrocardan® implant for painful isolated STT osteoarthritis have shown good results, but no paper has compared their medium-term outcomes. HYPOTHESES: Our main hypothesis would be that the Pyrocardan® implant, by preserving the carpal biomechanics, could lead to better wrist mobility. Our secondary hypotheses would be that no other clinical and radiological differences will be found between these two procedures at a mean 5 years follow-up. PATIENTS: In this non-randomised retrospective study, performed at two healthcare facilities, we report and compare the outcomes of STT arthrodesis with staple fixation versus the Pyrocardan® implant in 38 patients (40 thumbs) from 2 previously published cohorts. Twenty-one patients with a mean age of 68 years (range, 46-79) underwent STT arthrodesis in facility 1. Seventeen patients with a mean age of 61 years (range, 41-80) received a Pyrocardan® implant in facility 2. Patients were reviewed at both facilities by the same examiner who performed a clinical and radiographical assessment. RESULTS: At a mean follow-up of 8 years (range, 2-20 years) for the STT group and 5 years (range 3-8 years) for the Pyrocardan® group, we found no significant differences in the clinical and radiological outcomes between the two procedures except in wrist active extension and ulnar deviation, where Pyrocardan® appears to produce better mobility (extension 58°± 9 vs. 38°± 14 and ulnar deviation 35°[25, 40] versus 45°[40, 50]) (p<.001 and p<.008 respectively). The two surgical techniques led to significantly improvement in terms of pain relief, function, and strength. For the STT arthrodesis group, two complete non-unions were found (9%), while narrowing of the styloscaphoid joint space was found in eight thumbs (36%). For the Pyrocardan® group, four postoperative DISI (22%), four calcifications around the trapezium and/or distal scaphoid (22%) and one asymptomatic dislocation (6%) of the implant were observed. DISCUSSION: Pyrocardan® implant seems to result in better mobility in extension and ulnar deviation. STT arthrodesis and Pyrocardan® implant to treat isolated STT osteoarthritis led to less pain, better strength and functional scores, and restored wrist stability. A future study with a larger population will be needed to confirm these results. LEVEL OF EVIDENCE: IV.
ABSTRACT
PURPOSE: The aim of this study was to test the validity and reliability of the assessments of scapholunate (SL) instability status on 4-dimensional (4D) computed tomography (CT) using wrist arthroscopy as a reference standard. METHODS: Thirty-three patients (16 men, 17 women; mean age, 48 ± 13 years) with suspected SL instability were evaluated prospectively with 4D-CT and wrist arthroscopy. Based on the arthroscopic testing of SL joint, 2 groups were defined: group 1 (n = 8) consisted of patients who had no, or slight, SL malalignment in the midcarpal space and group 2 (n = 25) consisted of patients who had moderate or severe SL malalignment. Two independent readers, who did not know the arthroscopic findings, used 4D-CT to evaluate the SL gap, lunocapitate angle (LCA), and radioscaphoid angle (mean and range values) during radioulnar deviation. RESULTS: The interobserver reliability was deemed good or excellent for most of the 4D-CT variables, except for the LCA range (moderate) and SL gap range (poor). For both readers, the SL gap mean, maximum, and minimum values were significantly higher (+67%, +78%, and +39%, respectively) and the LCA mean was significantly lower (-17%) in group 2 than in group 1. The radioscaphoid angle range values were lower (-34%) and the radioscaphoid angle mean values slightly higher (+4%) in group 2, but there was no significant difference between the 2 groups. The SL gap range values were also higher (+86% for R1 and +40% for R2) and the LCA range values also lower (-50% for R1 and -31% for R2) in group 2. CONCLUSIONS: Quantitative 4D-CT data corresponded well with the arthroscopic dynamic analysis of the SL joint in patients with suspected chronic SL instability.

Preliminary results with the Tactys® modular gliding prosthesis for proximal interphalangeal joint (PIPJ) replacement were encouraging, with notable improvement in clinical and functional scores at 1 and 2 years' follow-up. However, a recent study found a trend for deterioration over time. We wanted to check this by analyzing medium-term outcomes. Sixty-four arthroplasties were performed in 48 patients in single facility between January 2015 and January 2020. Clinical, functional, and radiographic outcomes were analyzed at short- and medium-term follow-up for 15 of these arthroplasties. Mean follow-up of the 48 patients was 3.1 years. Pain significantly decreased on the numeric rating scale (p < 0.01) and the functional QuickDASH score improved from 67.3 to 55.9 (p < 0.01). Grip and pinch strengths were lower in the operated than in the contralateral hand (p = 0.04 and p = 0.6, respectively). PIPJ active range of motion (ROM) in flexion/extension improved from 44° to 49.4° (p = 0.17). 70% of the 48 patients were satisfied. Fifteen arthroplasties were analyzed at 17 and 61 months' follow-up. Pain relief continued. ROM decreased from 57° to 46° (p < 0.05) and the functional QuickDASH score deteriorated from 25.8 to 54.7 (p < 0.01). Both grip and pinch strength increased, with a significant difference in pinch (p = 0.003). The main complication was swan-neck deformity (46%), with a mean 11 months' onset. Our results confirmed the deterioration trend observed over time in the functional results of the Tactys® prosthesis despite, good patient satisfaction. LEVEL OF EVIDENCE: 4.

Background: The purpose of this retrospective study was to report outcomes of arthroscopic bone grafting and K-wire fixation to treat scaphoid non-union. Methods: We included in at two healthcare facilities, 42 consecutive patients (34 men, 8 women) with a mean age of 25 years (range 15-56 years) with scaphoid non-union of the proximal and middle third without intracarpal deformity or SNAC osteoarthritis. All patients were evaluated (pain, range of motion, strength, function, X-rays) by an independent examiner. Results: At the mean follow-up of 18 months (range 12-56), pain was significantly reduced from 7 to 1 on a visual analogue scale (out of 10). The scores on the Quick Disabilities of the Arm, Shoulder and Hand questionnaire and Patient Rated Wrist Evaluation were improved significantly. At the last review, grip strength was 83% of the contralateral side, the average wrist flexion-extension was 125° and the radioulnar deviation was 58°. Bone union was achieved in 37 cases (88%). The mean time of checking the bone union was 3 months (range, 2-8). Four patients required revision surgery because of failed union. Conclusions: Based on our findings, we found that this procedure can be used as a surgical treatment for scaphoid non-union of the proximal and middle third without intracarpal deformity or osteoarthritis. The arthroscopic bone grafting is a reliable, effective, and minimally invasive procedure.

BACKGROUND: Pollicization of the index finger can be considered the gold standard technique for the treatment of congenital thumb aplasia. The aim of this study was to review the described incisions for pollicization and to create an anatomical framework enabling the study and comparison of these incisions. METHODS: A systematic review was performed to collect descriptions of incision sets. An anatomical model was created from the two upper limbs of the same cadaver. Thumb aplasia was modeled on both hands of this cadaver by severing the thumbs; an index finger pollicization was performed on one of the two hands. Comparative analysis of scar positions, first web size, and neothumb aspect of each incision set was conducted using a surgical glove modeling the skin. The glove was fitted onto the aplastic model to draw the incisions and then onto the pollicized hand to adjust the resulting flaps after cutting. RESULTS: Twelve articles, two textbooks, and one DVD were included in the review, either containing an original description of incisions, or describing an incision pattern with figures and references to the initial author. A total of five different incision sets, described by Buck-Gramcko, Blauth, Foucher, Ezaki, and Malek, were identified and compared using the anatomical model. CONCLUSIONS: This work summarizes five original incisions described for index pollicization in thumb aplasia and presents a standardized and reliable model to study and compare these different sets. The model can be used for educational purposes, either to teach or to optimize an incision set.

Background In this study we sought to evaluate the contribution of dynamic four-dimensional computed tomography (4DCT) relative to the standard imaging work-up for the identification of the dorsal intercalated segment instability (DISI) in patients with suspected chronic scapholunate instability (SLI). Methods Forty patients (22 men, 18 women; mean age 46.5 ± 13.1 years) with suspected SLI were evaluated prospectively with radiographs, arthrography, and 4DCT. Based on radiographs and CT arthrography, three groups were defined: positive SLI ( n = 16), negative SLI ( n = 19), and questionable SLI ( n = 5). Two independent readers used 4DCT to evaluate the lunocapitate angle (LCA) (mean, max, coefficient of variation [CV], and range values) during radioulnar deviation. Results The interobserver variability of the 4DCT variables was deemed excellent (intraclass correlation coefficient = 0.79 to 0.96). Between the three groups, there was no identifiable difference for the LCA mean . The LCA max values were lower in the positive SLI group (88 degrees) than the negative SLI group (102 degrees). The positive SLI group had significantly lower LCA cv (7% vs. 12%, p = 0.02) and LCA range (18 vs. 27 degrees, p = 0.01) values than the negative SLI group. The difference in all the LCA parameters between the positive SLI group and the questionable SLI group was not statistically significant. When comparing the negative SLI and questionable SLI groups, the LCA cv ( p = 0.03) and LCA range ( p = 0.02) values were also significantly different. The best differentiation between patients with and without SLI was obtained with a LCA cv and LCA range threshold values of 9% (specificity of 63% and sensitivity of 62%) and 20 degrees (specificity of 71% and sensitivity of 63%), respectively. Conclusion In this study, 4DCT appeared as a quantitative and reproducible relevant tool for the evaluation of DISI deformity in cases of SLI, including for patients presenting with questionable initial radiography findings. Level of evidence This is a Level III study.
ABSTRACT
INTRODUCTION: The main aim of the present study was to compare motives between patients requesting secondary finger amputation following or unrelated to a work accident. The secondary objective was to assess correlation between sick leave duration and motive for amputation following a work accident. METHOD: A single-center retrospective study was conducted over an 11-year period in a hand clinic. Cases of secondary totalizing post-traumatic finger amputation at metacarpal base level were included. Exclusion criteria comprised non-traumatic amputation, age<16 years and thumb amputation. In all, 216 patients met the inclusion criteria. The main endpoints assessed motives in requests for secondary metacarpal base amputation: esthetic, functional or administrative. Secondary endpoints comprised accident-to-surgery interval, gender and age, amputated digit and dominant-side involvement. RESULTS: Motive correlated significantly with gender (p<0.05). Administrative motives almost exclusively concerned males (21 males, 1 female) and predominantly concerned work accidents (19 vs. 3). Accident-to-surgery intervals were significantly longer in case of administrative motive (25.7 months, vs. 10.8 months for functional and 9 months for esthetic motives). Accident-to-surgery intervals were significantly longer in case of work accidents (15.2 vs. 9.5 months). DISCUSSION: Age and gender influenced patients' attitudes in post-traumatic finger amputation. Work-accident status influenced attitudes in a quarter of cases; we consider it unlikely that this can be reduced to claims for compensation, but that it is rather a matter of undiagnosed pathological grief. These findings highlight the importance of early follow-up of victims of traumatic amputation and early screening for pathological grief.

Background: The purpose of this retrospective study was to report and compare the outcomes of the MAIA® prosthesis and trapeziectomy for trapeziometacarpal osteoarthritis. Methods: We included 92 consecutive patients (8 men, 84 women) with a mean age of 57 years (range 44-75 years) who underwent trapeziectomy (44 patients) or trapeziometacarpal joint replacement with a MAIA® prosthesis (48 patients) for painful osteoarthritis. All patients were evaluated (pain, range of motion, strength, function, X-rays) by an independent examiner. Results: The two groups of patients had comparable preoperative characteristics. At the mean follow-up of 9 years (range: 8-10), we found a significant reduction in pain levels for each group. In the final data review, there were no significant differences in terms of pain levels, grip strength, thumb active motion and the Quick Disabilities of the Arm, Shoulder and Hand score between the two groups. Pinch strength and the work performance score on the Michigan Hand Questionnaire were significantly better in the MAIA® prosthesis group. The MAIA® group had a shorter postoperative recovery time of 6 weeks and fewer patients required physiotherapy. Postoperatively, the thumb column length was significantly less in the trapeziectomy group. In this group, we found a significant decrease in the trapezial cavity height between the immediate postoperative evaluation and the final assessment, with three patients having painful scaphometacarpal impingement. Two patients required surgical revision for symptomatic meta-carpophalangeal joint hyperextension. In the MAIA® group, we found no implant subsidence, loosening, dislocation or fracture. None of the implants were revised. Conclusions: From this study, we found that the both procedures can be used as a surgical treatment for trapeziometacarpal osteoarthritis. The MAIA® prosthesis is a useful alternative to trapeziectomy and appears to be a reliable and effective implant in the medium- to long-term.

Vascular lesions of the hand are common and are distinct from vascular lesions elsewhere because of the terminal vascular network in this region, the frequent hand exposure to trauma and microtrauma, and the superficial location of the lesions. Vascular lesions in the hand may be secondary to local pathology, a proximal source of emboli, or systemic diseases with vascular compromise. In most cases, ischaemic conditions are investigated with Doppler ultrasonography. However, computed tomography angiography (CTA) or dynamic contrast-enhanced magnetic resonance angiography (MRA) is often necessary for treatment planning. MR imaging is frequently performed with MRA to distinguish between vascular malformations, vascular tumours, and perivascular tumours. Some vascular tumours preferentially affect the hand, such as pyogenic granulomas or spindle cell haemangiomas associated with Maffucci syndrome. Glomus tumours are the most frequent perivascular tumours of the hand. The purpose of this article is to describe the state-of-the-art acquisition protocols and illustrate the different patterns of vascular lesions and perivascular tumours of the hand.
ABSTRACT
We modified our original surgical technique of scapholunate intercarpal ligamentoplasty for treating chronic scapholunate dissociation. The aim of this study was to compare the outcomes in patients treated by the same surgical team with the original method and the modified method over two different time periods. Nineteen patients with a mean age of 40 years were treated with the original method (mean follow-up of 34 months, range 12-54), and 21 patients with a mean age of 38 years were treated with the modified method (mean follow-up of 27 months, range 13-40). In both groups, we found a significant improvement in pain levels, grip strength, functional scores in terms of QuickDASH and Patient-Rated Wrist Evaluation, and radiographic scapholunate gap and scapholunate angle after surgery. There were no significant differences between the two groups in outcome measures except the scapholunate gap, which was significantly better controlled by the modified procedure. Between the immediate postoperative period and the last follow-up, there was a significant increase in the scapholunate gap and scapholunate angle after the original method, while there only a small increase after the modified method. We conclude that both versions of the scapholunate intercarpal ligamentoplasty yield satisfactory clinical and radiological results in the short to mid-term. The modified method makes the triquetral surgical step easier and seems to better optimize the tension across the ligamentoplasty, thus maintaining the intercarpal correction.Level of evidence: III.

PURPOSE: To assess the validity and reliability of the posterior radioscaphoid angle (PRSA), an indicator of dorsal displacement of the scaphoid, in distinguishing wrists with and without chronic scapholunate instability (SLI). METHODS: We prospectively evaluated 40 patients (22 men and 18 women; mean age, 46 ± 13 years) with suspected SLI with radiographs and computed tomography arthrography. Based on these data, 3 groups were defined: positive SLI (n = 16), negative SLI (n = 19), and questionable SLI (n = 5). An independent reader measured the PRSA on sagittal computed tomography images using the same procedure. RESULTS: The PRSA median values were significantly lower in the negative SLI group (98°) compared with the positive SLI (110°) and questionable SLI (111°) groups. The difference between the positive SLI and questionable SLI groups was not significant. The best differentiation between patients with and without SLI was obtained with a PRSA threshold value of 103° (specificity of 86% and sensitivity of 79%). CONCLUSIONS: In this preliminary study, PRSA analysis offers a quantitative tool for the evaluation of dorsal scaphoid displacement in cases of SLI, including for patients presenting with questionable initial radiography findings.

INTRODUCTION: After traumatic upper-limb amputation (TULA), one-third of patients develop traumatic pathological grief (PG). However, are the other two-thirds unscathed? The main aim of the present study was to assess the rate of TULA victims claiming to have dealt with the consequences and showing no PG. The secondary objective was to determine positive and negative factors enabling and preventing coping. METHOD: A retrospective clinical study was conducted over an 11-year period in all adult TULA cases in our department. Assessment was on questionnaire. PG was assessed on the ICG (Inventory of Complicated Grief). Factors were assessed on physical, psychological, social, functional, esthetic and epidemiological criteria. Statistical analysis used StatView software, with the significance threshold set at p<0.05. RESULTS: Functional and social impacts were significantly greater in case of PG. Thumb amputation was significantly associated with PG, while PG was significantly less frequent in case of amputation at the metacarpal base. Patients in PG had significantly more often undergone neuroma resection or stump revision surgery. DISCUSSION: Fewer than a half of TULA victims achieved cure. Long-term prognosis depends on the patient's ability to accept the new situation, much more than on amputation level. Patients need support from the very first minutes, with follow-up extended well belong scar healing. Onset and healing of the narcissistic wound are inevitably delayed compared to skin healing.

We report the outcomes of four-corner arthrodesis for advanced wrist collapse in 50 patients (51 wrists) using a dorsal locking plate. At a mean follow-up of 6 years (range 4-9), pain was significantly reduced and wrist function was significantly improved compared with preoperative status. After four-corner arthrodesis, grip strength was 80% of the contralateral side, and wrist motion averaged 50° flexion-extension and 30° radioulnar deviation. Immobilization time was 5 weeks (4-6) and sick-leave was 3 months (2-5) following surgery. There were seven nonunions (14%) that underwent repeat arthrodesis. Three wrists were later converted to total arthrodesis due to persisting pain. Radiographic dorsal impingement was found in five wrists after four-corner arthrodesis and did not require reoperation. The outcomes appear not remarkably different from those reported using other fixation methods other than an apparent earlier return to activities.Level of evidence: IV.

PURPOSE: To compare the accuracy of evaluating deformity in distal radius malunions using plain radiographic measurements compared with a 3-dimensional method involving 3-dimensional computer bone models. METHODS: Consecutive patients who had an extra-articular distal radius malunion were included. Standard radiographs and computed tomography scans of both wrists were performed. Palmar tilt, radial tilt, and ulnar variance were measured on radiographs. The computed tomography scan data were sent to a workstation and 3-dimensional bone surface models of the radius were created. The 3-dimensional palmar tilt, 3-dimensional radial tilt, 3-dimensional ulnar variance, and axial rotational deformity were calculated. RESULTS: Thirteen patients, mean age 40 years (range, 22-57 years) were included. The 3 3-dimensional values were positively correlated with their corresponding radiographic values. Nevertheless, the 3-dimesional palmar tilt and 3-dimensional radial tilt values were slightly smaller than the radiographic palmar tilt and radial tilt. The quantitative difference between the 3-dimensional method and plain radiographs was on average 2° for the dorsal deformity group and 3° for the palmar deformity group. The 3-dimensional ulnar variance was significantly higher than the radiographic ulnar variance by an average of +1.3 mm for malunions with dorsal tilt and +0.6 mm for malunions with palmar tilt. The 3-dimensional method allowed us to measure the extent of the axial rotational deformity, which was 9° on average (range, 2° to 21°). CONCLUSIONS: Despite small differences, measurements made on both plain radiographs and 3-dimensional computer bone models are accurate for evaluating the deformity in extra-articular distal radius malunions. Our 3-dimensional method seems to provide a more accurate measurement of ulnar variance, particularly for dorsally angulated cases, and is helpful for measuring rotational malalignment. CLINICAL RELEVANCE: In this study, we found that either a 3-dimensional computer bone model or plain radiographs can be used as a benchmark to evaluate the deformity of extra-articular distal radius malunion. The 3-dimensional method can also be used to define axial rotational deformity.

INTRODUCTION: The main aim of the present study was to determine the existence of pathological grief in victims of traumatic upper-limb amputation. The secondary objective was to determine risk factors for onset of pathological grief. METHOD: A retrospective clinical study was conducted for an 11-year period, including all cases of traumatic upper-limb amputation in adults. Patients were assessed on a questionnaire including an adaptation of the Inventory of Complicated Grief (ICG). Risk factors were assessed on surgical, personal occupational and subjective criteria. Statistical analysis on StatView software used matched Chi2 tests for comparisons, with the significance threshold set at p<0.001. RESULTS: With 1058 questionnaires sent out, the response rate was 52%; 3% of returned questionnaires were non-interpretable. Thirty-nine percent showed a state of pathological grief. Risk factors comprised lack of attempted replantation (p<0.001), isolated thumb amputation (p<0.001), and multi-digit or macro-amputation (p<0.001). Subjective esthetic blemish or the feeling of being mutilated was significantly associated with pathological grief (both p<0.001). DISCUSSION: Traumatic upper-limb amputation victims incurred a risk of pathological grief (main endpoint), with identifiable risk factors (secondary endpoint). Victim accompaniment and screening for risk of pathological grief are essential to limit the psychological impact of trauma and promote social and occupational reintegration.

In the serious forms of Dupuytren disease, passive extension during surgery often results in unmasking a loss of skin substance that makes primary closure impossible. Our objective in this study was to describe and assess the therapeutic possibilities of a 3 local flaps surgical approach in serious forms of Dupuytren disease, using the lateral skin expansion because of the cord. A cadaveric study was carried out on 12 adult nonembalmed, fresh frozen hands. For each specimen, a loss of skin substance was simulated on the palmar side of the fifth finger at the level of the proximal digital flexion crease. Coverage involved an incision delineating 3 distinct local flaps: a radially based quadrangular palmar flap, triangular proximally based laterodigital flap, and a distally based triangular web space flap. For a defect reaching up to 40% of the palmar surface of the first phalanx (P1), this 3-flap combination allowed us to fill in skin loss with a tension-free closure. Then we led a clinical study among 10 patients suffering from Dupuytren contracture, Tubiana, and Michon classification stages from II to IV. For those patients who all showed perioperative inadequate skin coverage, we used the 3-flap plasty. No skin necrosis occurred. This reliable technique using a "cascade" of local flaps makes it possible, in serious forms of Dupuytren disease, to both easily access the palmar and digital portions of the cord and to achieve closure.

We performed a prospective study to evaluate the values of dynamic four-dimensional computed tomography in assessing suspected chronic scapholunate instability. Forty patients were evaluated with radiographs, arthrography, and four-dimensional computed tomography. On plain radiographs and computed tomography, we found 16 patients with definite scapholunate instability, five with questionable scapholunate instability, and 19 with absence of scapholunate instability. We used four-dimensional computed tomography to evaluate the size of the scapholunate gap during radioulnar deviation. The mean and maximal values of the gap size were lowest in the patients with absence of scapholunate instability and highest in those with definite scapholunate instability. When comparing the scapholunate gap sizes of the patients with absent and questionable scapholunate instability, the range of the gap sizes was significantly higher in the patients with questionable scapholunate instability. We conclude that four-dimensional computed tomography aids assessment of chronic scapholunate instability, which allows the differentiation between patients without and those with definite or questionable scapholunate instability. Level of evidence: II.

Background Radioscapholunate (RSL) fusion is a surgical option to manage radiocarpal osteoarthritis. Many authors upgrade the procedure by adding distal scaphoid excision with or without excision of the triquetrum. Our objective was to identify the prognostic factors for good clinical and radiographic outcomes of RSL arthrodesis. Purpose Distal scaphoid excision improves both scaphotrapeziotrapezoidal osteoarthritis and radiocarpal fusion, and excision of the triquetrum is not critical to achieving satisfactory outcomes. Methods In this retrospective and bicentric investigation, all wrists were managed with RSL fusion for posttraumatic radiocarpal osteoarthritis. A total of 85 patients were included and evaluated at the revision by clinical (pain, wrist motion, and strength), functional (Disabilities of the Arm, Shoulder, and Hand questionnaire, Patient-Related Wrist Evaluation score, and Modified Mayo Wrist Score), and radiological (scaphotrapeziotrapezoidal, midcarpal osteoarthritis, and radiocarpal nonunion) examinations. We assessed prognostic factors for clinical and radiographic (osteoarthritis and nonunions) outcomes. Results The average follow-up was 9.1 years (1-21.4). Work-related accidents adversely impacted the clinical outcomes, and distal scaphoid excision significantly improved them and decreased scaphotrapeziotrapezoidal osteoarthritis and nonunion. Neither distal scaphoid excision nor excision of the triquetrum influenced midcarpal osteoarthritis. Radiocarpal fusion was significantly promoted by memory staples and bone grafting. Discussion Distal scaphoid excision should be preferred to improve the functional results while decreasing scaphotrapeziotrapezoidal osteoarthritis and radiocarpal nonunion rates. Excision of the triquetrum appears to be an alternative to radioulnar resection-arthroplasty to solve ulnocarpal impaction syndrome. Strict surgical procedure must be observed to promote RSL fusion combining solid bone fixation and the use of bone graft. Level of evidence This is a level IV, case series, retrospective series.
