Efficacy and Safety of Oral Tranexamic Acid vs. Other Routes in Total Joint Arthroplasty: A Systematic Review and Network Meta-Analysis.

BACKGROUND: Total joint arthroplasty (TJA) is often associated with significant blood loss, leading to complications such as acute anemia and increased risk of infection and mortality. Tranexamic acid (TXA), an antifibrinolytic agent, has been recognized for effectively reducing blood loss during TJA. This systematic review and network meta-analysis aims to evaluate the efficacy and safety of oral TXA compared with other administration routes in TJA. METHODS: Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a comprehensive literature search was conducted across multiple databases, including PubMed, Scopus, Embase, and Web of Science, focusing on randomized clinical trials involving oral TXA in TJA. The studies were assessed for quality using the Cochrane risk assessment scale. Data synthesis involved network meta-analyses, comparing outcomes including hemoglobin drop, estimated blood loss (EBL), transfusion rate, and deep vein thrombosis (DVT) rate. RESULTS: Our comprehensive literature search incorporated 39 studies with 7,538 participants, focusing on 8 TXA administration methods in TJA. The combination of oral and intra-articular (oral + IA) TXA markedly reduced hemoglobin drop more effectively than oral, intravenous (IV), and IA alone, but the difference was not significant. Oral + IA TXA significantly reduced EBL more effectively than oral + IV, IA + IV, and oral, IV, and IA alone. Perioperative transfusion rates with oral + IA TXA was significantly lower than that of oral, IA, and IV alone. The DVT rate with oral + IA was significantly lower than that with all other routes, including oral + IV, IA + IV, and oral, IA, and IV alone. CONCLUSION: Oral TXA, particularly in combination with IA administration, demonstrates significantly higher efficacy in reducing blood loss and transfusion rates in TJA, with a safety profile comparable with that of other administration routes. The oral route, offering lower costs and simpler administration, emerges as a viable and preferable option in TJA procedures. LEVEL OF EVIDENCE: Level I.

Effectiveness of physiotherapy plus acupuncture compared with physiotherapy alone on pain, disability and grip strength in people with carpal tunnel syndrome: A randomized clinical trial.

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome in the upper extremities. Acupuncture is often used as a treatment method in CTS and numerous studies consider it effective. However, no study has yet compared the efficacy of physical therapy including bone and neural mobilization, exercise and electrotherapy with and without acupuncture in CTS patients. PURPOSE: comparing the effect of physiotherapy plus acupuncture with physiotherapy alone on pain, disability and grip strength in CTS patients. METHOD: Forty patients with mild to moderate CTS were randomly divided into two equal groups. Both groups received exercise and manual techniques for 10 sessions. Patients in the physiotherapy plus acupuncture group also received 30 min of acupuncture in every session. The visual analog scale (VAS) score, the score on the Boston carpal tunnel questionnaire for functional status and symptom severity, shortened disability of arm, shoulder, hand (Quick-DASH) score and grip strength were evaluated at pre-test and post-test. RESULTS: According to ANOVA results, there is a significant interaction between group and time for VAS, BCTQ and Quick-DASH parameters. At the post-test, while the parameters of VAS, BCTQ and Quick-DASH in the physiotherapy plus acupuncture group had a statistically significant difference compared to the physiotherapy group, no significant difference was observed between the two groups in the pre-test. Moreover, there is no significant difference between groups in grip strength improvement. CONCLUSION: This study shows preliminary evidence that physiotherapy plus acupuncture, was more effective than physiotherapy alone in pain relief and improving disability of patients suffering from CTS.

Cross-cultural adaptation, validation and responsiveness of the Persian version of Western Ontario shoulder instability index questionnaire in Persian patients with shoulder instability.

INTRODUCTION: To translate, cross-culturally adapt, and psychometric testing the Western Ontario Shoulder Instability index (WOSI) into Persian. METHODS: Seventy-two patients diagnosed with shoulder instability participated in reliability, construct validity, and responsiveness analysis. All the patients filled out the WOSI with an interval of two weeks to assess reliability. The shortened Disability of Arm, Shoulder and Hand (Quick-DASH), Shoulder Pain and Disability Index (SPADI), and the 36-Item Short-Form Survey (SF-36) were assessed to evaluate construct validity. In order to assess responsiveness patients filled out WOSI before and after the physiotherapy and global rating of change scale at last session of physiotherapy. Reliability was assessed by intra-class correlation coefficient (ICC (1,2)), construct validity by two tailed Pearson (r), and responsiveness by longitudinal validity and receiver operating characteristics (ROC) curve analysis. RESULTS: The ICC (1,2) was 0.90 and correlation analysis revealed high level of correlation with: Quick-DASH (r = 0.82); SPADI (r = 0.72); physical SF-36 (r = -0.52); and mental SF-36 (r = -0.48). Responsiveness analysis demonstrated the area under curve was 0.90, with minimal clinical important difference 46.87. CONCLUSION: We found the Persian-WOSI as a valid, reliable, and responsive questionnaire to evaluate quality of life of patients with shoulder instability.

The effectiveness of comprehensive physiotherapy compared with corticosteroid injection on pain, disability, treatment effectiveness, and quality of life in patients with subacromial pain syndrome: a parallel, single-blind, randomized controlled trial.

OBJECTIVE: Comparing short- and long-term effects of comprehensive physiotherapy (CP) and subacromial corticosteroid injection (SCI) on pain, disability, and quality of life in the patients with subacromial pain syndrome (SAPS). DESIGN: 2 × 4 randomized controlled trial. PARTICIPANTS: 50 participants with unilateral SAPS. INTERVENTION: Random assignment with allocation concealment into two groups labeled as 12 sessions, supervised CP (n = 22) and 1cc triamhexal SCI (n = 25). OUTCOMES: Visual Analog Scale (VAS), Shoulder Pain and Disability Index (SPADI), shortened Disabilities of Arm, Shoulder and Hand (Quick-DASH), and Western Ontario Rotator Cuff Index (WORC). Outcomes were gathered pre- and post-intervention, with three- and six-month follow-ups. RESULTS: Variance analysis revealed that there was a significant interaction of group-in-time for SPADI and WORC (P < .05) but not for Quick-DASH and VAS (P > .05). The independent t-test analysis showed that the mean scores of all outcome measures in CP group were lesser than SCI group via 6 months (P < .05), except for the VAS (P > .05, mean difference = -0.97, 95% confidence interval -2.11-0.15). CONCLUSION: CP results in statistically significant and potentially clinically important difference in function and quality of the life at all timeframe. Moreover, there was no between group difference in order to reduce pain.

Comparing the effect of physiotherapy and physiotherapy plus corticosteroid injection on pain intensity, disability, quality of life, and treatment effectiveness in patients with Subacromial Pain Syndrome: a randomized controlled trial.

PURPOSE: To compare the short and medium-term effects of physiotherapy plus corticosteroid injection (combined) with physiotherapy alone on pain intensity, disability, Quality of Life (QoL), and treatment effectiveness in patients with Subacromial Pain Syndrome (SAPS). METHODS: In this double-blind, parallel Randomized Controlled Trial (RCT), 50 patients with SAPS were randomly assigned into combined (N = 25, a single injection 3-6 days before physiotherapy) and physiotherapy alone group (N = 25). Pain, disability, QoL, and treatment-effectiveness were measured at pre-intervention, post-intervention, and 3 and 6-month follow-up with Visual Analog Scale (VAS), Shortened Disability of the Arm, Shoulder, and Hand (Quick-DASH), Shoulder Pain and Disability Index (SPADI) (primary outcome measure), Western Ontario Rotator Cuff (WORC), and Global Rating of Change (GRC) respectively. A 2 × 4 (group × time) mixed model analysis of variance (ANOVA) was applied for analysis. RESULTS: The ANOVA revealed statistically significant group-in-time interaction for all outcome measures (p-value < 0.05). The independent t-test showed more effectiveness in the combined group at medium-term, as the mean scores of almost all outcome measures were substantially lesser (p < 0.01). Moreover, in short-time, despite a greater number of patients stating "completely recovered" in the combined group, there was no statistically significant difference between groups. CONCLUSIONS: Effects of physiotherapy plus corticosteroid injection could be more long-lasting than physiotherapy alone in improving pain intensity, disability, QoL, and treatment effectiveness in patients with SAPS. TRIAL REGISTRATION NUMBER: IRCT20201010048980N1.IMPLICATIONS FOR REHABILITATIONShoulder pain is common, persistent, and predominantly results from subacromial pain syndrome (SAPS).Physiotherapy and corticosteroid injections are effective interventions for this condition.Comprehensive physiotherapy alone can be as effective as corticosteroid injection combined with physiotherapy in the short term.A combined approach versus physiotherapy alone may have more medium-term effects on SAPS patients' pain, disability, quality of life, and treatment effectiveness.

Shoulder and scapula muscle training plus conventional physiotherapy versus conventional physiotherapy only: a randomized controlled trial of patients with lateral elbow tendinopathy.

BACKGROUND: Previous studies have suggested that weakening of shoulder and scapula muscles have been associated with increased pain, and decreased functional abilities in patients with lateral elbow tendinopathy (LET). PURPOSE: To compare the effects of shoulder and scapula muscle training plus conventional physiotherapy with conventional physiotherapy only. METHODS: A group of 48 patients with LET was randomly allocated into two groups: shoulder and scapula muscle training plus conventional physiotherapy (n = 24), and conventional physiotherapy (n = 24). All patients received 12 sessions of treatment for 4 weeks. Furthermore, both groups were instructed to continue their own exercise program at home until four months after the end of treatment. Pain intensity, grip strength, and functional status were measured preintervention, postintervention, and 4 months after the end of intervention (4-month follow-up). RESULTS: The shoulder and scapula muscle training plus conventional physiotherapy group showed significantly more reduction in pain and greater improvement in functional status compared with conventional physiotherapy group, but there was no significant difference in pain-free grip strength for two groups. CONCLUSION: Conventional physiotherapy combined with shoulder and scapula muscle training could be more effective in improving the pain and functional abilities of patients with LET compared with conventional physiotherapy only.

3D printing-assisted fabrication of a patient-specific antibacterial radial head prosthesis with high periprosthetic bone preservation.

We present a novel fabrication and surgical approach for anatomical reconstruction of a fractured radial head using a patient-specific radial head prosthesis (RHP) made of polymethylmethacrylate (PMMA) bone cement. To this end, the use of PMMA bone cement for prosthesis fabrication was initially investigated using computational modeling and experimental methods. The RHP was fabricated through casting of PMMA bone cement in a silicone mold in the operating room before implantation. To enhance the precision of bony preparation for replacement of the radial head, a patient-specific surgical guide for accurate resection of the radial neck with the desired length was developed. Post-surgical clinical examinations revealed biomechanical restoration of elbow function, owing to the use of the patient-specific RHP and surgical guide. Importantly, follow-up radiographs after a mean follow-up of 18 months revealed bone preservation at the bone-prosthesis interface without any signs of erosion of the capitellum. Taken together, our method demonstrated the safety and efficacy of the PMMA RHP in restoring elbow biomechanics. This also provides a very safe and cost-effective method for making various patient-specific prostheses with localized antibacterial delivery and close mechanical properties to native bone for improved periprosthetic bone regeneration. The clinical trial of this study was registered at Mashhad University of Medical Sciences under the trial registration number 970493.

Ultrasound Evaluation for Incomplete Carpal Tunnel Release.

Background: Ultrasound can provide evaluation of the anatomy of the carpal tunnel in a convenient, noninvasive office setting. This study is intended to determine the accuracy and diagnostic performance of ultrasound, used by surgeons, for the evaluation of completeness of carpal tunnel release (CTR). Methods: Ten cadaver arms underwent randomized sectioning of 0%, 25%, 50%, 75%, or 100% of the transverse carpal ligament. Following a brief training session, a blinded observer used ultrasound to evaluate the percentage of the transverse carpal ligament release. The release amount was then confirmed with an open exposure of the transverse carpal ligament. Results: Cronbach α and Pearson correlation coefficients were 0.92 and 0.87, demonstrating excellent reliability and validity of the technique. Diagnostic performance including sensitivity, specificity, positive predictive value, and negative predictive value was 100%, 75%, 86%, and 100%, respectively, for the diagnosis of incomplete release of the transverse carpal ligament by a novice sonographer orthopedic surgeon. Conclusions: The ultrasound is a highly accurate tool for the diagnosis of incomplete transverse carpal ligament release and requires a minimal amount of training to use for this purpose. It provides a rapid means of diagnosing incomplete release of the transverse carpal ligament following CTR.

One-stage surgical treatment for concomitant rotator cuff tears with shoulder stiffness has comparable results with isolated rotator cuff tears: a systematic review.

BACKGROUND: Addressing preoperative shoulder stiffness before rotator cuff repair (RCR) is advocated, but the effectiveness of this approach is debatable. We hypothesized that 1-stage treatment of concomitant rotator cuff tear (RCT) with shoulder stiffness has comparable results with isolated RCT. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the databases including MEDLINE, Embase, Cochrane Library, and Scopus were searched using the keywords of "shoulder stiffness" OR "adhesive capsulitis" OR "frozen shoulder" AND "rotator cuff." Studies that met all the criteria compared the 2 arms of isolated RCT vs. RCT with concomitant shoulder stiffness, received no physical therapy before surgery, and reported data of preoperative and postoperative range of motion (ROM) and functional outcomes after surgery. RESULTS: Four level III studies met the inclusion criteria. The non-stiff group (isolated RCT) included 460 patients who underwent RCR; the stiff group (RCT with concomitant shoulder stiffness) included 111 patients who underwent RCR and manipulation under anesthesia with or without capsular release. There were significant differences in preoperative ROM between stiff and non-stiff groups. At final follow-up, there were no statistical differences in all ROM between the 2 groups. There was no significant difference in comparing preoperative and postoperative outcome scores including visual analog scale for pain, Constant, modified American Shoulder and Elbow Surgeons, and University of California-Los Angeles scores. CONCLUSIONS: Concomitant surgical treatment of nonmassive RCT and moderate shoulder stiffness in 1 stage may have comparable results to the surgical treatment of RCT in patients without preoperative stiffness. Therefore, a physical therapy regimen before surgical intervention may not be necessary.

Psychometric Properties of the Persian Version of the Simple Shoulder Test (SST) Questionnaire.

BACKGROUND: To validate the Persian version of the simple shoulder test in patients with shoulder joint problems. METHODS: Following Beaton`s guideline, translation and back translation was conducted. We reached to a consensus on the Persian version of SST. To test the face validity in a pilot study, the Persian SST was administered to 20 individuals with shoulder joint conditions. We enrolled 148 consecutive patients with shoulder problem to fill the Persian SST, shoulder specific measure including Oxford shoulder score (OSS) and two general measures including DASH and SF-36. To measure the test-retest reliability, 42 patients were randomly asked to fill the Persian-SST for the second time after one week. Cronbach's alpha coefficient was used to demonstrate internal consistency over the 12 items of Persian-SST. RESULTS: ICC for the total questionnaire was 0.61 showing good and acceptable test-retest reliability. ICC for individual items ranged from 0.32 to 0.79. The total Cronbach's alpha was 0.84 showing good internal consistency over the 12 items of the Persian-SST. Validity testing showed strong correlation between SST and OSS and DASH. The correlation with OSS was positive while with DASH scores was negative. The correlation was also good to strong with all physical and most mental subscales of the SF-36. Correlation coefficient was higher with DASH and OSS in compare to SF-36. CONCLUSION: Persian version of SST found to be valid and reliable instrument for shoulder joint pain and function assessment in Iranian population.

Side-to-Side Versus Pulvertaft Extensor Tenorrhaphy-A Biomechanical Study.

PURPOSE: We hypothesized that a side-to-side (STS) tendon repair has biomechanical characteristics that match those of a Pulvertaft (PT) weave. METHODS: Thirty extensor tendons were harvested (4 extensor digitorum communis and 1 extensor indicis proprius from 6 cadaver arms). Three hand surgery fellows with similar backgrounds of training under the same conditions and precise standardized technique performed the repairs (5 PT and 5 STS per surgeon). After the repairs, the tendons were passed through a graft-sizing guide to determine bulk and results were expressed as a repaired versus native diameter ratio. The specimens were then tested for ultimate strength and fatigue properties. Failure type and mechanical properties were recorded and compared with those of the native tendon. RESULTS: The average peak force to failure was 93 ± 20 N for the STS and 62 ± 32 N for PT group. Relative strength ratio (repair strength compared with native tendon strength) was 37% ± 21% for the STS and 22% ± 11% for the PT group. In the STS group, all failures occurred as a result of tissue failure; however, in the PT, suture failures occurred in 3 tendons before tissue failure. The mean bulk ratio of the repaired site versus native proximal tendon was 37 ± 14% and 40% ± 22% more for the STS and PT groups, respectively. These values for native distal tendon were 28% ± 9.9% and 26% ±24 %, respectively for STS and PT repair. Furthermore, the bulk of the repaired site for the STS and PT groups was 4.2 ± 0.50 and 4.7 ± 1.2 mm, respectively. CONCLUSIONS: Side-to-side repair technique showed superior biomechanical properties while demonstrating comparable repair bulk of the tendon coaptation compared with the Pulvertaft weave. CLINICAL RELEVANCE: The results of this study may help guide a surgeon's choice of repair technique when addressing tendon injuries or tendon transfers.

A Meta-Analysis of the Effect of Corticosteroid Injection for Enthesopathy of the Extensor Carpi Radialis Brevis Origin.

PURPOSE: The null hypothesis that there is no effect of corticosteroid injection on visual analog scale for pain in patients with enthesopathy of the extensor carpi radialis brevis (eECRB) origin 6 months after treatment was tested. Our secondary hypotheses were that there is no effect of corticosteroid injection on pain intensity at 1 and 3 months after treatment; that there is no effect of corticosteroid injection on grip strength at 1, 3, and 6 months after treatment; and that there is no effect of corticosteroid injection on Disabilities of the Arm, Shoulder, and Hand scores at 1, 3 and 6 months after treatment. METHODS: EMBASE, PubMed Publisher, MEDLINE, OvidSP, Web of Science, Google Scholar, and the Cochrane Central were searched for relevant studies. Studies were eligible if there was (1) a description of corticosteroid injection treatment for eECRB; (2) randomized placebo injection-controlled trials with at least 10 adults included with eECRB; (3) a full-text article available with data describing the mean differences between the corticosteroid and the control groups and the outcome measures used; and (4) follow-up of at least 1 month. In total, 7 randomized controlled trials comparing the effect of corticosteroid injection with a placebo injection on symptoms of eECRB were included in our meta-analysis. RESULTS: We found no difference in pain intensity 6 months after injection of corticosteroids or placebo. Pain intensity was slightly, but significantly, lower 1 month, but not 3 months, after steroid injection. There were no significant differences in grip strength or Disabilities of the Arm, Shoulder, and Hand score at any time point. CONCLUSIONS: This meta-analysis showed that there is no difference in pain intensity between corticosteroid injection and placebo 6 months after injection. We interpret the weight of evidence to date as suggesting that corticosteroid injections are neither meaningfully palliative nor disease modifying when used to treat eECRB. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

Involvement of the lesser sigmoid notch in elbow fracture dislocations.

BACKGROUND: This study addressed the primary null hypothesis that there is no difference in the articular surface area of the lesser sigmoid notch involved among Mayo classes. Secondarily, we analyzed the fracture line location and the pattern of lesser sigmoid notch articular surface involvement among Mayo classes. METHODS: Using quantitative 3-dimensional computed tomography, we reconstructed and analyzed fractures involving the lesser sigmoid notch articular surface in 52 patients. Further, we assessed the surface area involved in the fracture, the number of fracture fragments, and the location and direction of the fracture lines. Coronoid fractures were classified according to Mayo types. RESULTS: There was no significant difference between Mayo types 1 and 2 in any characteristic of the involvement of the lesser sigmoid notch articular surface, whereas Mayo type 3 was significantly different from both Mayo types 1 and 2 in the area involved in the fracture (42% in Mayo type 3 vs. 9% in Mayo types 1 and 2), the number of articular fragments (>3 fragments in type 3 vs. 2 fragments in types 1 and 2), and the direction of fracture line (both horizontal and vertical lines in type 3 vs. only horizontal line in types 1 and 2). CONCLUSION: Mayo type III results in a more complex fracture, which might need to be addressed directly or indirectly during open reduction with internal fixation of olecranon fracture dislocations because changes in the geometry of lesser sigmoid notch may affect the radioulnar joint if it remains incongruent.

Cross-Cultural Adaptation, Validation, and Reliability Testing of the Modified Oswestry Disability Questionnaire in Persian Population with Low Back Pain.

STUDY DESIGN: Prospective study. PURPOSE: We aimed to validate the Persian version of the modified Oswestry disability questionnaire (MODQ) in patients with low back pain. OVERVIEW OF LITERATURE: Modified Oswestry low back pain disability questionnaire is a well-known condition-specific outcome measure that helps quantify disability in patients with lumbar syndromes. METHODS: To test the validity in a pilot study, the Persian MODQ was administered to 25 individuals with low back pain. We then enrolled 200 consecutive patients with low back pain to fill the Persian MODQ as well as the short form 36 (SF-36) questionnaire. Convergent validity of the MODQ was tested using the Spearman's correlation coefficient between the MODQ and SF-36 subscales. Intraclass correlation coefficient (ICC) and Cronbach's α coefficient were measured to test the reliability between test and retest and internal consistency of all items, respectively. RESULTS: ICC for individual items ranged from 0.43 to 0.80 showing good reliability and reproducibility of each individual item. Cronbach's α coefficient was 0.69 showing good internal consistency across all 10 items of the Persian MODQ. Total MODQ score showed moderate to strong correlation with the eight subscales and the two domains of the SF-36. The highest correlation was between the MODQ and the physical functioning subscale of the SF-36 (r=-0.54, p<0.001) and the physical component domain of the SF-36 (r=-0.55, p<0.001) showing that MODQ is measuring what it is supposed to measure in terms of disability and physical function. CONCLUSIONS: Persian version of the MODQ is a valid and reliable tool for the assessment of the disability following low back pain.

Factors associated with operative treatment of enthesopathy of the extensor carpi radialis brevis origin.

BACKGROUND: This study investigated the factors associated with variation in the rate of surgery for enthesopathy of the extensor carpi radialis brevis (eECRB). METHODS: We used a large database from 3 academic hospitals including 5964 patients with the diagnosis of eECRB from 2001 to 2007. Of those, 244 patients (4%) had surgery for eECRB. We used the date of the first encounter as the date of diagnosis. We also recorded the date of the first cortisone injection and surgery for eECRB. We used Cox multivariable regression analysis to find factors associated with surgery. We considered the following explanatory factors: age, sex, race, diabetes, a diagnosis of major depression, a diagnosis of an anxiety disorder, hospital, provider (surgeon vs. nonsurgeon), corticosteroid injection, and the time from diagnosis to the first cortisone injection. RESULTS: The hazard ratio of having surgery was 12-times greater if the initial provider was an orthopedic surgeon rather a nonsurgeon and 1.7-times greater at 1 of the 2 hospitals. The rate of surgery varied substantially, ranging from 0% to 22%. Corticosteroid injection delayed the time to surgery but was ultimately associated with a higher rate of surgery. The majority (86%) of surgeries were done within 1 year of the first documented office visit. CONCLUSIONS: It seems likely that an emphasis on the preferences and values of the patient rather than the surgeon would decrease the variation in surgery rates for eECRB observed in this study. Methods for optimizing the influence of patient preferences and values on decision making (eg, decision aids) merit additional study.

Factors associated with removal of a radial head prosthesis placed for acute trauma.

PURPOSE: This study tests the hypothesis that there are no factors associated with removal or revision of a radial head prosthesis. A secondary analysis addressed the time to removal or revision. METHODS: We reviewed the database of two large hospitals from 2000 to 2014 and identified 278 patients that had radial head replacement after an acute fracture or fracture dislocation of the elbow: 19 had removal and 3 had revision of the radial head implant within the study period. Explanatory variables including demographics, the type of injury, prosthesis type, surgeon, medical centre, and associated injuries were evaluated. Survival analysis using Kaplan-Meier curves evaluated time to removal/revision. RESULTS: After adjustment for potential confounders using Cox regression multivariable analysis, hospital was the only factor independently associated with removal or revision (Hazard ratio=2.4, Confidence interval: 1.03-5.8, P value=0.043). The highest proportion of removal/revision was during the first year after implantation and decreased by half each year over the second to fourth years. The most common reason for removal of the prosthesis was to facilitate removal of heterotopic ossification (the majority with proximal radioulnar synostosis) rather than technical error or problems with the prostheses. CONCLUSION: These findings suggest that the decision to remove a radial head prosthesis may depend more on surgeon or hospital preferences than on objective problems with the prosthesis. Until clarified by additional study, removal of a prosthesis should not be considered an objective outcome in research. In addition, patients offered removal of a radial head prosthesis, might get the opinion of more than one surgeon at more than one hospital before deciding whether or not to proceed. LEVEL OF EVIDENCE: Level III Prognostic.

Distal Radius Volar Rim Fracture Fixation Using DePuy-Synthes Volar Rim Plate.

Background To assess the results of distal radius fractures with the involvement of the volar rim fixed with the DePuy-Synthes Volar Rim Plate. Case Description We searched for the patients with volar rim fracture and/or volar rim fractures as part of a complex fracture fixed with a volar rim plate. Ten patients met the inclusion criteria: three patients with type 23B3, six patients with type 23C, and one patient with very distal type 23A. The mean follow-up was 14 months (range: 2-26). Fractures healed in all patients. Of the three patients with isolated volar rim fractures (type 23B3), two patients had no detectable deficits in motion. These patients had an average Gartland and Werley score of 9 (range: 2-14). Of the other seven patients (six with type 23C and one with type 23A fracture), three patients healed with full range of motion and four had some deficits in range of motion. Two patients had excellent results, three had good results, and two had fair results using the Gartland and Werley categorical rating. One patient healed with a shortened radius and ulnar impingement requiring a second surgery for ulnar head resection arthroplasty. Literature Review Results after nonoperative treatment of volar rim fractures are not satisfactory and often require subsequent corrective osteotomy. Satisfactory outcomes are achieved when the fragments are well reduced and secured regardless of the device type. Clinical Relevance Volar rim plates give an adequate buttress of the volar radius distal to volar projection of the lunate facet and do not interfere with wrist mobility. Furthermore, the dorsal fragments can be fixed securely through the volar approach eliminating the need for a secondary posterior incision. However, patients should be informed of the potential problems and the need to remove the plate if symptoms develop.

Update of the Quick DASH Questionnaire to Account for Modern Technology.

Background: Almost 2 decades have passed since the development of the items contained in the Quick Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and during this time, daily tasks have changed to adapt to changes in technology. Methods: A cohort of 108 patients completed demographic information, the Quick DASH (both standard and technologically updated versions), and 2 Patient-Reported Outcomes Measurement Information System (PROMIS)-based computerized adaptive testing questionnaires: PROMIS pain interference and upper-extremity function. To create a technologically updated Quick DASH, we substituted 3 items from the standard Quick DASH questionnaire with 3 other items related to the use of technology: (1) Text or dial with your cell phone, (2) Type on a keyboard, and (3) Use a computer mouse. Results: The technologically updated Quick DASH questionnaire had lower scores compared with the standard Quick DASH (37 vs. 33, respectively), but they had a large correlation and both had high internal consistency. The items "Text or dial with your cell phone" and "Use a computer mouse" in the updated Quick DASH questionnaire had the lowest scores. Except for affected side, the standard Quick DASH and updated Quick DASH were influenced by the same factors. PROMIS pain interference was the only independent variable affecting both questionnaire scores. Conclusions: A technologically updated Quick DASH had no advantage over the standard Quick DASH.
