RESUMO
This case report describes the 4-year outcomes of proximal interphalangeal joint arthroplasty in a 14-year-old girl with a stiff joint after trauma. At follow-up, active range of motion was 35°, she was pain-free and satisfied with the outcome. Implant arthroplasty seems to be a valuable option for young patients with persistent post-traumatic stiff and deviated PIP joints to-at least temporarily-increase quality of life.

PURPOSE: There is ongoing discussion about the level of symptoms patients with proximal interphalangeal (PIP) joint osteoarthritis should have to undergo surgery. The aims of our study were to determine the minimal important change (MIC) and patient acceptable symptom state (PASS) for PIP joint range of motion (ROM), and define clinically relevant thresholds of preoperative pain and function at which patients have the greatest chance to achieve a MIC and PASS in these outcomes 1 year after PIP arthroplasty. METHODS: We analyzed registry data that included patients with PIP joint osteoarthritis who underwent an arthroplasty for this condition and had a 1-year follow-up. Patients indicated pain on a numeric rating scale (0-10) and completed the brief Michigan Hand Outcomes Questionnaire (MHQ). Active total PIP ROM was measured. The preoperative thresholds, predictive of achieving the MIC and PASS for each outcome measure of pain, function, and ROM, were determined using receiver operating characteristics curves. RESULTS: We included 196 patients who experienced a relevant improvement in ROM (= MIC) when there was an increase by ≥8° compared with the ROM preoperatively. Patients were satisfied with their postoperative ROM (= PASS) if they achieved PIP mobility of at least 66°. Pain at rest and during activities was predictive for achieving a MIC but not a PASS. Due to an insufficient area under the curve for the brief MHQ and ROM, their baseline values cannot predict the postoperative achievement of MIC or PASS. We suggest that patients with preoperative pain at rest ≥4.5 or pain during activities ≥5.5 have the greatest chance of achieving a subjectively relevant change 1 year after surgery. CONCLUSIONS: The determined thresholds may support surgeons in the preoperative process of deciding for or against a surgical intervention and explain the probability of achieving sufficient postoperative symptom relief for the patient. LEVEL OF EVIDENCE: Prognostic I.
RESUMO
PURPOSE: We evaluated the 1-year postoperative clinical and patient-reported outcomes in patients who had a 3-dimensional planned corrective osteotomy of their distal radius, radial shaft, or ulnar shaft using a printed, anatomical, patient-tailored plate to determine the feasibility and effectiveness of this methodology. METHODS: Simulations in computer-assisted preoperative planning of corrective osteotomies resulted in 3-dimensionally printed surgical guides, surgical models, and anatomically customized plates for application at the distal radius and forearm. Patients with malunions of the distal radius or forearm who underwent fixation with the custom-made plates were documented in our registry. Grip strength and range of motion assessments were made before surgery (baseline), as well as at 6 weeks and 3 and 12 months. Additionally, patients rated their wrist-related pain and disability using the Patient-Rated Wrist Evaluation. RESULTS: Fifteen patients underwent corrective surgery, and the 1-year follow-up data of 14 patients with a median age of 56 years (interquartile range, 24-64 years) were available for analysis. The median baseline Patient-Rated Wrist Evaluation score improved from 47 to 7 after 1 year. The flexion-extension arc of motion of the wrist increased from 90° at baseline to 130° at 1 year and the pronation-supination arc of motion of the wrist increased from 135° to 160° in the same time period. Differences in radiological measurements for palmar and radial inclinations, as well as for ulnar variance between the affected and contralateral wrists, were reduced with the osteotomy. In 1 case, the plate was removed 11 months after the osteotomy. No severe adverse events were reported. CONCLUSIONS: Three-dimensionally planned and printed patient-tailored plates offer a reliable method for correcting even complex malunions of the distal radius and forearm. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
RESUMO
INTRODUCTION: The aim was to analyse complications after surface replacing and silicone proximal interphalangeal (PIP) joint arthroplasty. MATERIALS AND METHODS: All complications, reoperations (subsequent intervention without implant modification) and revisions (subsequent surgery with implant modification or removal) were extracted out of our registry for two cohorts: (1) Patients who received a surface replacing arthroplasty at the PIP joint using the CapFlex-PIP prosthesis and (2) patients who received a PIP silicone implant. Furthermore, radiographs were evaluated for deviations from the longitudinal finger axis. RESULTS: In our registry, 279 surface replacing implants and 424 silicone implants have been documented. The overall complication rate was 20% for surface replacements and 11% for silicone arthroplasties (p ≤ 0.01) with soft tissue-related events being the most prevalent in both groups. Reoperations were significantly more frequent after surface replacement (5.4%) than silicone arthroplasty (0.5%; p ≤ 0.001), while the revision rates did not differ significantly (4.4% and 3.3%, respectively; p = 0.542). Postoperative axis deviations were significantly less frequent in the surface replacement group (19% versus 58% for silicone arthroplasty; p ≤ 0.001). CONCLUSION: We recommend using a surface replacing implant in fingers with preoperative axis deviations and correctable anatomical situation, bearing in mind the higher risk of a second surgery. However, treatment outcomes also need to be considered before choosing one implant over another.

BACKGROUND: For the treatment of deformed finger middle joints that occur as a result of osteoarthritis or inflammatory and post-traumatic destruction, artificial joint replacement is an option to arthrodesis. Hereby mobility can be obtained, which is why this method generally has a higher acceptance. DISCUSSION: What clinical and subjective results can be expected after artificial finger middle joint replacement and what is the expected complication rate for the different types of joints? MATERIAL AND METHODS: We present our experiences with artificial joint replacement with various implants over the past decades as well as promising new developments of the last 10 years. RESULTS: The silicone implant still remains the gold standard in joint replacement. For these implants, good long-term results and low revision rates have been documented. Due to the soft flexible material, however, lateral stability and preoperatively-existing axis deviations seem problematic. Initial studies with modular resurfacing implants appear promising and may eventually replace the silicone spacer over the long term. Consequently, long-term results of these modern implants are pending. CONCLUSIONS: Painful osteoarthritis of the finger joint can be treated well with motion-preserving artificial joints. The complication rate appears to be decreasing. New generation modular surface prostheses seem to be relatively equal to the silicone spacer in terms of long-term outcomes.

PURPOSE: The objective of this randomized controlled trial was to compare the 12-month postoperative Michigan Hand Outcomes Questionnaire (MHQ) total score between patients with osteoarthritis (OA) at the first carpometacarpal (CMC I) joint who underwent trapeziectomy with suspension-interposition arthroplasty using the flexor carpi radialis (FCR) tendon and those receiving a human dermal collagen template (allograft). METHODS: We included 60 patients with CMC I OA who met the indications for surgery. They were randomized into 1 of 2 groups: trapeziectomy using the FCR tendon or trapeziectomy with the allograft for suspension-interposition. Patients completed a set of questionnaires including the MHQ and were clinically assessed at baseline, 6 weeks, and 3, 6, and 12 months after surgery. Complications were recorded. RESULTS: We operated on 29 patients using the FCR tendon; 31 patients received an allograft. Baseline MHQ total scores significantly increased from 51 (95% confidence interval [CI], 46-56) to 83 (95% CI, 78-87) and 53 (95% CI, 47-58) to 76 (95% CI, 69-84) by 12 months in the FCR and allograft groups, respectively. We found similar outcomes for both groups at all follow-up assessments. Five complications occurred in the FCR group, and 10 in the allograft group. Revision surgery was required for one allograft patient. CONCLUSIONS: The use of the FCR tendon or allograft for trapeziectomy with suspension-interposition arthroplasty in patients with CMC I OA leads to similar outcomes with more complications, mainly tendon irritations, associated with the latter. Therefore, we only use the allograft in cases of severe instability requiring a larger amount of suspension-interposition material or for revision procedures after failed suspension-interposition with the FCR tendon. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

PURPOSE: The brief Michigan Hand Outcomes Questionnaire (briefMHQ) was developed as a shorter version of the Michigan Hand Outcomes Questionnaire (MHQ), but its measurement properties have not been investigated in patients with Dupuytren contracture. The objective of the study was to investigate the reliability, validity, responsiveness, and interpretability of the briefMHQ. METHODS: Fifty-seven patients diagnosed with Dupuytren contracture completed the briefMHQ as well as the full-length MHQ and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire at baseline. Two to 14 days after baseline and 1 year after collagenase injection or surgery, patients again filled out the briefMHQ. Reliability was determined using the intraclass correlation coefficient and by calculating internal consistency (Cronbach alpha). Validity was tested by quantifying correlations with the full-length MHQ and QuickDASH. Responsiveness, based on the standardized response mean and the minimally clinically important change, was also determined. RESULTS: The briefMHQ had an intraclass correlation coefficient of 0.87, Cronbach alpha of 0.88, and correlations of r = 0.88 and -0.82 with the original MHQ and QuickDASH, respectively. The standardized response mean was 0.9 and the minimally clinically important change was 7 points. CONCLUSIONS: Overall, the briefMHQ demonstrates excellent reliability, good validity, and high responsiveness in patients with Dupuytren contracture. CLINICAL RELEVANCE: The briefMHQ is an accurate and time-saving tool to evaluate patients with Dupuytren contracture and the effect of a corresponding treatment.

INTRODUCTION: Primary press fit and secondary osteointegration is a precondition for component anchoring in articular surface replacements, also in the case of proximal interphalangeal (PIP) joint. Nevertheless, many existing prostheses for the PIP joint have failed to show sufficient osteointegration. CapFlex-PIP(©) implant is a modular metal-polyethylene surface replacement for the PIP joint consisting of a proximal and distal component each having a titanium pore backside, which allows secondary osteointegration at the bone-implant interface. To evaluate osseous integration of this implant, we report a histological analysis of an explantation of a CapFlex-PIP(©) finger implant. CASE PRESENTATION: We present a case of a removed CapFlex-PIP(©) implant due to a soft tissue complication in an 84-year-old woman. The patient received bisphosphonate medication as treatment for osteoporosis. For the histological analysis, the bone-implant contact (BIC) was measured on all stained sections using a Zeiss Axioplan microscope. The summated BIC was 40.7 % for the proximal component and 46.5 % for the distal component of the implant. Histology showed that the implant was in direct contact with the bone at various locations, with no signs of wear or degradation. CONCLUSIONS: This case demonstrates successful osteointegration of the CapFlex-PIP(©) implant. Both components of the investigated implant show osseous integration to an extent which is comparable to that of other load-bearing and articulating implants at different locations in the human body.

PURPOSE: To evaluate the one-year postoperative clinical and patient-rated outcomes in patients receiving proximal interphalangeal (PIP) joint arthroplasty with a modular surface gliding implant, CapFlex-PIP. METHODS: 10 patients each with primary osteoarthritis of a single PIP joint were assessed preoperatively (baseline), at 6 weeks, and 3, 6, and 12 months after CapFlex-PIP arthroplasty for lateral stability and range of motion of the affected digit. In addition, patients rated their pain using a numeric rating scale and function and overall assessment of their treatment and condition using the quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Patient Evaluation Measure (PEM) questionnaires, respectively. RESULTS: The mean baseline active mobility of the affected PIP joint increased from 42° to 51° by one year, although this change was not significant. Patients reported reduced pain at one year, which was statistically significant. There was also a significant improvement between baseline and one-year QuickDASH (43 points vs 15 points, respectively) and PEM scores (51 vs 25 points, respectively). Absent or low lateral instability was observed in 9 joints at follow-up. All implants remained intact over the one-year postoperative period and there was no migration, osteolysis, or implant fracture. After study completion, 2 patients underwent tenolysis. CONCLUSIONS: Patients experienced a significant reduction in pain and a trend towards increased mobility. All implants showed complete osteointegration without evidence of radiological migration. Lateral stability improved. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

INTRODUCTION: The evaluation of patient satisfaction is becoming increasingly important in assessing treatment outcomes. The objective of this study was to analyze the determinants of treatment satisfaction in patients with trapeziometacarpal osteoarthritis (TMC OA) after surgery or corticosteroid injection. MATERIALS AND METHODS: Prospective cohort study of patients with TMC OA who received surgery or corticosteroid injection was carried out. Socio-demographic and clinical data were recorded at baseline and 1 year after the intervention, and patients filled out the Michigan Hand Outcomes Questionnaire (MHQ). On a 5-point Likert scale, patients reported baseline expectations, expectation fulfillment at 1 year, as well as satisfaction with the treatment result. To identify determinants of satisfaction, we entered these variables into one ordered logistic regression model for surgical patients and another for patients with injection. RESULTS: We included 146 patients, 88 of whom were treated surgically. With respect to satisfaction at 1 year, 87 % of the surgical patients were somewhat or very satisfied with the treatment result, whereas only 49 % of the patients with injection were satisfied. Expectations being fulfilled was the only determinant of treatment satisfaction in the surgical group. In the injection group, a more advanced Eaton stage of TMC OA and greater pain at 1 year were associated with reduced satisfaction. CONCLUSIONS: Surgery for TMC OA leads to high patient satisfaction, whereas only half of the patients treated with corticosteroid injection were satisfied with the treatment result. An advanced stage of TMC OA and higher pain lead to reduced treatment satisfaction in the latter group, indicating that corticosteroid injection is only effective for patients in a lower stage of disease. As fulfillment of expectations was an important determinant of satisfaction in the surgical group, we emphasize the need to provide comprehensive information prior to surgery, so that the patient's expectations of treatment outcome are realistic.

PURPOSE: To evaluate the indications for revision of silicone proximal interphalangeal joint arthroplasties, to analyze the results of revision surgery, and to determine which specific patient concerns were most successfully addressed by revision surgery. METHODS: This study combined a cross-sectional evaluation of the patients' condition after revision surgery and a retrospective chart review. All patients who had revision surgery of their PIP silicone arthroplasty in our clinic between 1999 and 2009 were invited for clinical follow-up. We reviewed their medical records, took radiographs, and recorded the active flexion and extension, pain, and patient satisfaction. RESULTS: Thirty-four revisions in 27 patients were performed, and we were able to examine 20 patients with 24 arthroplasties clinically. The average follow-up was 4.3 years after revision and 8.3 years following primary surgery. The main indications for revision surgery were pain and restricted active range of motion, with or without implant breakage, predominantly in the index and middle fingers. Patients were fairly satisfied with the outcome of the revision surgery and reported only mild residual pain. Patients whose indication for revision was a restricted active range of motion increased active flexion from 33° before the revision to 71° following the operation. Patients who required revision for a large ulnar deviation deformity (mean, 33°) still had a residual deviation of 15° at follow-up. CONCLUSIONS: Revision surgery after failed silicone proximal interphalangeal joint arthroplasty was most successful in patients with severe postoperative stiffness. Pain was relieved, and patients were fairly satisfied with the results of the revision. Ulnar deviation could not be corrected completely. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Proximal row carpectomy (PRC) is an established surgical procedure used to treat post-traumatic osteoarthritis of the wrist with sparing of the midcarpal joint and advanced aseptic necrosis such as lunatomalacia. Proximalization of the distal carpal row following PRC may lead to secondary problems such as radiocarpal impingement. At follow-up, two of our patients complained about ulnar-sided wrist pain after proximal row carpectomy. Computed tomography (CT) scans were taken for both patients with an additional magnetic resonance imaging scan for one patient. The CT scan revealed clear osteolysis consistent with a pisiform bone impingement on the ulnar styloid process in both the cases, and also on the hamate in one patient. An impingement syndrome of this nature has not previously been described and should be kept in mind when patients report ulnocarpal symptoms after PRC.

OBJECTIVES: The aim was to evaluate patient satisfaction with online video consultations in assessing hand disorder. MATERIAL AND METHODS: This prospective study included patients who attended a video consultation, either as an initial meeting to assess the need for further evaluation or treatment or as an early postoperative follow-up consultation. After the consultation, they completed a satisfaction questionnaire. Regression models were used to reveal determinants of patient satisfaction. RESULTS: We included 100 patients, with a mean age of 55 years (range 17-81 years). 95% were satisfied or very satisfied. The main reasons for choosing this form of consultation were shorter travel and wait times. Age, gender and educational level did not determine satisfaction. Significant factors for dissatisfaction were insufficient video and sound quality. CONCLUSION: Online video consultation in hand surgery is a valuable alternative to in-clinic appointments for all age groups. However, it is crucial to ensure adequate video and audio quality.

We compared the effects of capsule resection versus capsule suturing in patients treated with a dual-mobility trapeziometacarpal joint prosthesis. We included 131 patients with capsular resection and 57 patients with repair. The mean scores for pain and the brief Michigan Hand Outcomes Questionnaire were similar between the groups preoperatively and at 6 weeks and 1 year postoperatively. Mean key pinch strength was also similar in both groups before surgery and at 1 year, but higher in the capsular resection than in the suture group at 6 weeks. The incidence of complications reported throughout the 1-year postoperative period was not significantly different between the groups. One implant in the capsular resection group was revised for reasons most likely unrelated to capsule management. We conclude that the capsule can be safely resected during trapeziometacarpal joint implant arthroplasty.Level of evidence: III.
RESUMO
Arthrodesis of a painful and destroyed wrist is one of the key operations in patients with rheumatoid arthritis. Clayton is given credit for the first description of an operative technique of wrist arthrodesis by means of an intramedullary Steinmann pin. Mannerfelt popularized this technique by using a Rush pin and additional fixation with staples. The aim of the present article is to give a detailed description of the operative technique used in our hospital. Over a period of 13 years, 104 modified Clayton-Mannerfelt arthrodeses were performed in 87 patients with rheumatoid arthritis. Ninety-three wrists were reviewed clinically and radiographically. The patients had high fusion rates and a reliable reduction in preoperative pain, with a low rate of complications. The pin technique is more versatile than standard wrist arthrodesis plates, and the wrist can be positioned according to the needs of the patient. This technique seems to be a good alternative to conventional wrist arthrodesis using an arthrodesis plate in wrists destroyed by rheumatoid arthritis, even in situations with difficult bone stock. In most cases, it is not necessary to remove the hardware.

We compared the short-term recovery of patients treated with trapeziometacarpal joint (TMJ) implant arthroplasty versus resection-suspension-interposition (RSI) arthroplasty. Implant patients (n = 147) had a better 3-month postoperative brief Michigan Hand Outcomes Questionnaire (MHQ) score (mean 82) compared to RSI patients (n = 127), who had a mean score of 69. Key pinch strength at 3 months was also higher in the implant group compared to the RSI group (6.8 kg vs. 3.1 kg). At 1 year, both groups had similar brief MHQ scores, but key pinch remained higher in the implant group (7.0 kg vs. 3.9 kg [RSI]). After implant arthroplasty, employed patients returned to work after a mean of 44 days, which was significantly faster than the 84 days for RSI patients. Patients after TMJ implant arthroplasty recover significantly faster in the first 3 postoperative months compared to RSI patients. However, 1-year postoperative outcomes are similar for both cohorts, with key pinch strength remaining higher for patients with TMJ implant arthroplasty.Level of evidence: II.

We analysed complications, revision surgeries, and patient-reported and clinical outcomes 2 years after trapeziometacarpal joint implant arthroplasty using the Touch® prosthesis. Of 130 operated patients with trapeziometacarpal joint osteoarthritis, four had to be revised owing to implant dislocation, loosening or impingement, leading to an estimated 2-year survival rate of 96% (95% confidence interval: 90 to 99). Of 101 patients available for the 2-year follow-up, complications occurred in 17, with the most frequent being de Quervain stenosing vaginosis (n = 6) and trigger thumb (n = 5). Pain at rest decreased significantly from a median value of 5 (interquartile range [IQR]: 4 to 7) before surgery to 0 (IQR: 0 to 1) at 2 years. Key pinch strength increased significantly from 4.5 kg (IQR: 3.0 to 6.5) to 7.0 kg (IQR: 6.0 to 8.0). We recommend surgery with the Touch® prosthesis as the standard procedure for patients with isolated trapeziometacarpal joint osteoarthritis because of the high survival rate and promising outcomes at 2 years.Level of evidence: IV.
RESUMO
The purpose of this study was to analyse the 1-year outcomes after combining a surface replacing proximal interphalangeal joint arthroplasty and a distal interphalangeal screw arthrodesis and to compare the combined surgery with proximal interphalangeal joint arthroplasty alone. To obtain two groups with similar baseline data from our prospective registry, propensity score matching was used to match 23 fingers with the combined operations with 115 fingers with proximal interphalangeal joint arthroplasty alone. One year after surgery, the mean ranges of motion were 60° (95% CI: 53° to 67°) in the combined group and 63° (95% CI: 60° to 66°) in the control group and did not differ significantly. Grip strength, the brief Michigan Hand Questionnaire and pain also did not differ between the groups 1 year after surgery. All the proximal interphalangeal implants in patients treated with a distal interphalangeal screw arthrodesis remained in situ. Combining proximal interphalangeal joint arthroplasty with distal interphalangeal arthrodesis leads to 1-year outcomes that are similar to those achieved by proximal interphalangeal joint replacement alone.Level of evidence: III.

INTRODUCTION: Patients with hand disorders frequently experience difficulties opening peelable packaging. PURPOSE: To investigate the forces patients can apply to tear tabs and to compare the results with normative data to make recommendations for the industry and clinical practice. STUDY DESIGN: Descriptive, cross-sectional. METHODS: One hundred patients with hand disorders were studied. The pinch pull force (PPF) applied to tear tabs of different lengths and materials (aluminum, plastic) was measured with a specially designed device. Key pinch was measured with a pinch gauge. Normative data were taken from another study on 402 healthy adults. RESULTS: Patients were able to apply most force to the longest aluminum tab, using the key grip, but this was only 53% of the force exerted by healthy people. Key pinch determines PPF (R(2)=0.548, p≤0.001). CONCLUSIONS: Manufacturers should provide long aluminum tear tabs. Health professionals are encouraged to measure key pinch to detect difficulties in opening packages. LEVEL OF EVIDENCE: Level IV.
