Intramedullary headless screw fixation for fractures of the proximal phalanges of the hand: a three-year follow-up

ObjectiveThe objective of this study was to evaluate the long-term outcomes of trans-articular intramedullary fixation using cannulated headless screws for proximal phalanx fractures in the hand.BackgroundVarious surgical techniques have been described for the fixation of proximal phalanx fractures, with Kirschner wires, plates, and screws being commonly used. The objective of this study was to evaluate the long-term outcomes of trans-articular intramedullary fixation using cannulated headless screws for proximal phalanx fractures in the hand. Methods Eight patients, with nine proximal phalanx fractures, treated with intramedullary screw fixation, were included for a follow-up visit three years post-surgery. Subjective and objective outcome measures were assessed using the Michigan Hand Questionnaire (MHQ), active range of motion (aROM), grip strength, conventional X-rays, and digital tomosynthesis images.MethodsEight patients, with nine proximal phalanx fractures, treated with intramedullary screw fixation, were included for a follow-up visit three years post-surgery. Subjective and objective outcome measures were assessed using the Michigan Hand Questionnaire (MHQ), active range of motion (aROM), grip strength, conventional X-rays, and digital tomosynthesis images.ResultsWe observed a mean MHQ score of 83%, a total aROM of 216.4°, and a Jamar grip strength of 29.9 kg in the injured hand. Digital tomosynthesis revealed complete fracture consolidation in all cases. Joint arthrosis was detected in only one case, attributed to a misplaced screw.ConclusionsOur findings indicate favorable long-term clinical outcomes, including range of motion, grip strength, patient satisfaction, and prevention of joint damage, with the use of intramedullary headless screw fixation.Level of evidence: Level IV, Therapeutic

Medial Femoral Trochlea Osteochondral Flap Reconstruction of the Previously Unsalvageable Kienbock-Associated Lunate With a Coronal Split

Patients with Kienbock disease can present with coronal fracture and collapse of the proximal lunate (Unified B2/Bain grade 1, 2B). Traditionally, this was considered unsalvageable. However, medial femoral trochlea (MFT) osteochondral reconstruction, used to recreate the proximal lunate surface, can be paired with reduction and repair of the coronal plane fracture, thus restoring midcarpal congruity. The purpose of this study was to report radiographic and clinical outcomes following lunate coronal fracture fixation at the time of MFT osteochondral reconstruction. This was a retrospective study performed at a single institution. We identified patients with Kienbock disease who underwent MFT osteochondral reconstruction from 2014 to 2023. Patients were included if they had a coronal fracture of the lunate distal articular surface fixed at the time of surgery. Radiographic and clinical parameters were evaluated, including carpal height ratio, union rate, presence of heterotopic ossification, need for revision surgery, and patient-reported outcome measures. Thirty-three patients were included, with a mean age of 27.5 years (range: 15-41); 19 (58%) were women. Mean radiographic follow-up time was 5.8 months, and mean clinical follow-up time was 22.6 months. Union was achieved in 30/33 patients (91%). Carpal height ratio improved from 1.32 to 1.4. Two patients (6%) required reoperation, one for removal of heterotopic ossification and another for conversion to proximal row carpectomy. Patients demonstrated meaningful improvement in brief Michigan Hand Questionnaire and Patient-Reported Outcomes Measurement Information Upper Extremity scores. Range of motion before and after surgery was similar. Lunate coronal fracture fixation with MFT osteochondral reconstruction represents an additional management option in select patients with Kienbock disease. This technique restores the midcarpal joint during lunate reconstruction and may allow patients to avoid salvage procedures. Early radiographic and clinical outcomes are promising. Therapeutic IV.

Preoperative predictors of two-year satisfaction in hand and wrist surgery patients

PurposeAs stakeholders seek to improve patient outcomes while maintaining cost-effectiveness in an increasingly expensive healthcare system, metrics such as patient satisfaction are becoming more important. This present study sought to identify factors associated with and independently predictive of better surgical satisfaction two years following hand and wrist surgery. MethodsPatients undergoing hand and wrist surgery at an urban outpatient institution were enrolled preoperatively into a surgical registry and assessed two years postoperatively. Patient satisfaction with surgery was measured at two years postoperatively with the Surgical Satisfaction Questionnaire (SSQ-8). Bivariate analysis determined associations between postoperative satisfaction and patient demographics, injury specifiers, medical history, and multiple patient-reported outcomes (PROs). Multivariable analysis determined independent predictors of two-year postoperative satisfaction following hand and wrist surgery. ResultsBetter surgical satisfaction was associated with having never smoked, no preoperative opioid use, lack of an accompanying legal claim, lack of a workers compensation claim, no clinical history of depression/anxiety, less comorbidities, and higher preoperative expectations.Various PROs relating to function, pain, activity, and general health at both baseline and two years demonstrated associations with postoperative satisfaction. Multivariable analysis confirmed that never smoking, lack of a legal claim, and better preoperative Brief Michigan Hand Questionnaire scores were independently predictive of better surgical satisfaction two years following hand and wrist surgery. ConclusionAt two years following hand and wrist surgery, better patient satisfaction was best predicted by never smoking, no related legal claim, and better baseline Brief Michigan Hand Questionnaire scores.

Polyethylene Glycol-Mediated Axonal Fusion Promotes Early Sensory Recovery After Digital Nerve Injury: A Randomized Clinical Trial

Background. Peripheral nerve repair is limited by Wallerian degeneration coupled with the slow and inconsistent rates of nerve regrowth. In more proximal injuries, delayed nerve regeneration can cause debilitating muscle atrophy. Topical application of polyethylene glycol (PEG) during neurorrhaphy facilitates the fusion of severed axonal membranes, immediately restoring action potentials across the coaptation site. In preclinical animal models, PEG-fusion resulted in remarkable early functional recovery. Methods. This is the first randomized clinical trial comparing functional outcomes between PEG-fusion and standard neurorrhaphy. Participants with digital nerve transections were followed up at 2 weeks, 1 month, and 3 months postoperatively. The primary outcome was assessed using the Medical Research Council Classification (MRCC) rating for sensory recovery at each timepoint. Semmes-Weinstein monofilaments and static two-point discrimination determined MRCC ratings. Postoperative quality of life was measured using the Michigan Hand Questionnaire (MHQ). Results. Forty-eight transected digital nerves (25 control, 23 PEG) across twenty-two patients were analyzed. PEG-fused nerves demonstrated significantly higher MRCC scores at 2 weeks (OR 16.95, 95% CI: 1.79 – 160.38, p = 0.008) and 1 month (OR 13.40, 95% CI: 1.64 – 109.77, p = 0.009). Participants in the PEG cohort also had significantly higher average MHQ scores at 2 weeks (Hodge’s g 1.28, 95% CI: 0.23 – 2.30, p = 0.0163) and 1 month (Hodge’s g 1.02, 95% CI: 0.04 – 1.99, p = 0.049). No participants had adverse events related to the study drug. Conclusion. PEG-fusion promotes early sensory recovery and improved patient well-being following peripheral nerve repair of digital nerves.

Patient-Perceived Hand Function Can Predict Treatment for Dupuytren Disease.

Web-based patient-reported outcome measures (PROMs) could help surgeons remotely assess the need for examination and subsequent treatment of patients with Dupuytren disease (DD). The authors studied whether the Unité Rhumatologique des Affections de la Main (URAM) and the Michigan Hand Questionnaire (MHQ) could predict DD treatment. In this prospective cohort study, the authors compared MHQ and URAM scores of treated patients with those of untreated patients. For the treatment group, the authors selected a score closest to 1 year before treatment. For controls, the authors randomly selected a score. The authors also tested the predictive value of a 1-year change score between 15 months and 6 weeks before treatment. The primary outcome measure was DD treatment. The predictive value was determined using the area under the curve (AUC). An AUC greater than 0.70 was considered good predictive ability; 0.70 to 0.50, poor predictive ability; and less than 0.50, no predictive ability. The authors included 141 patients for the MHQ analysis and 145 patients for the URAM analysis. The AUC of the MHQ and URAM scores measured 1 year before treatment were 0.80 (95% CI, 0.71 to 0.88) and 0.75 (95% CI, 0.68 to 0.82), respectively. The 1-year change score resulted in an AUC less than 0.60 for both questionnaires. The results show that both the MHQ and URAM score measured around 1 year before treatment can predict treatment for DD. If future studies show that telemonitoring of patients with DD with PROMs is also cost-effective, web-based PROMs could optimize patient care and effectiveness of DD treatment. Risk, III.

Outcomes of single digit replantation for amputation proximal to the flexor digitorum superficialis insertion: A systematic review with meta-analysis.

A single digit amputated proximal to the flexor digitorum superficialis (FDS) insertion is a relative contraindication to replantation. The aim of this study is to conduct a systematic review on replantation of these injuries to synthesize best available evidence on outcomes. This review was registered in PROSPERO under registration number CRD42021277305. A MEDLINE, CENTRAL, and EMBASE databases search yielded 1536 studies. Primary clinical studies on single digit replantation and functional outcome with at least 10 cases were included. Data on revision amputation and replantation distal to the FDS were collected as comparators. Data extracted included demographics, type of digit, level of injury, secondary surgeries, duration of sick leave, survival, function, and patient-reported outcomes. All studies were assessed using the Risk of Bias In Non-randomized Studies of Intervention (ROBINS-I) tool and data synthesis was completed using RevMan and Microsoft Excel. Six studies representing 182 replanted single digits that were amputated proximal to the FDS insertion were included. The average PIPJ motion of replanted single digits was 50° in those amputated proximal to the FDS insertion compared to 82.5 in those amputated distal to the FDS. The average Michigan Hand Questionnaire (MHQ) score was 84.78 in replantation group versus 76.81 in the amputation group which was statistically significant (p< .00001). Mean Disability of Arm, Shoulder, and Hand Questionnaire (DASH) score was 12 in replantation group compared to 18.5 in amputation group, however this was not statistically significant (p= .17). Few studies exist on outcomes of single digit replantations proximal to FDS insertion. Although range of motion is inferior in the replant group, this has increased since initial studies were performed, and patient satisfaction and patient reported outcomes are high. This is promising evidence for achieving reasonable outcomes in replantation of single digits amputated proximal to the FDS. Level III.

Does the Use of Gelled Platelet-Rich Plasma during Fixation of Subacute Proximal Pole Scaphoid Fractures Help? – A Single Centre Experience

Background: Subacute proximal pole scaphoid fractures (1 month to 6 months) have a higher risk of non-union. The aim of the present retrospective analysis is to evaluate the efficacy of gelled platelet-rich plasma (GPRP) as additional treatment to antegrade headless screw fixation of proximal pole scaphoid fractures. Methods: Forty-one patients were divided into two groups based on surgical treatment received: screw fixation alone (group A) and screw fixation and GPRP application at the fracture site (group B). A short cast was maintained for 4 weeks after surgery. Outcome measures included time to union, need for additional procedures, time to return to work, disabilities of the arm, shoulder, and hand (DASH) questionnaire, Michigan Hand Questionnaire (MHQ) and Mayo wrist score (MWS).Time to union was determined by monthly radiographs and confirmed by a computerized tomographic (CT) scan done at 4 months. Results: Union was achieved in 85.7% of patients in group A and in 100% of patients in group B. Patients in group B showed a faster time to healing (2.3 ± 0.4 months vs 3.1 ± 0.7 months, p = 0.0001) and earlier return to work (10.4 ± 2.2 vs 15.1 ± 2.9, p = 0.0001). There were no significant differences in patient-rated outcomes scores between the two groups at final follow-up. Conclusions: Internal fixation alone is effective in treating subacute proximal pole scaphoid fractures. GPRP application improves bone healing and functional recovery. Level of Evidence: Level III (Therapeutic).

Short incision versus minimally invasive surgery with tool-kit for carpal tunnel syndrome release: a prospective randomized control trial to evaluate the anterior wrist pain and time to return to work or activities

Trial designThe prospective randomized controlled trial.BackgroundThis study compares outcomes in terms of early postoperative anterior wrist pain and time to return to work or activities of daily living of patients who underwent carpal tunnel syndrome (CTS) release with short incision and those who had minimally invasive surgery (MIS) with CTS kits.MethodsA total of 24 patients diagnosed with primary CTS confirmed with electrodiagnosis at an academic university hospital were randomly assigned into one of two groups of 12 patients each: a short incision group and an MIS with tool-kit group using computer-generated block randomization (block of four). Sequentially numbered, opaque, sealed envelopes were used in the allocation concealment process. In the short incision group, skin was incised longitudinally from Kaplan’s line to the area distal to transverse wrist crease (2.5–4.0 cm) while in the tool-kit group, an incision of less than 2.5 cm. was made using special MIS-CTS kits. Primary outcomes evaluated include visual analogue scale (VAS) measurement of pain intensity in the anterior carpal area both while at rest and while conducting daily activities at the 2nd week postoperatively as well as the time to return to activities of daily living and work. Improvement in the Michigan hand questionnaire (MHQ) score, a secondary outcome, was also measured at the 2nd week postoperatively. Patients, allocator and outcome assessor were blinded.ResultsDemographic data, including preoperative electrodiagnostic severity and occupation, were similar in the two groups. There were no significant differences in terms of VAS of the early postoperative anterior carpal area at rest (p > 0.99), while conducting daily activities (p = 0.89) and time to return to activities of daily living (p = 0.46) and work (p = 0.24). The MHQ score improvement at the 2nd week postoperatively showed no significant difference between the groups (p = 0.95). The MIS wound length in the tool-kit group was significantly shorter than in the short incision group (1.95 vs 2.92 cm, p < 0.01).ConclusionsThere is no difference in early postoperative anterior wrist pain, time to return to work or to activities of daily living between the surgical techniques. Short incision is recommended for benefit in term of cost-effectiveness, while MIS with tool-kit could be preferred in patients who concerned in cosmetic appearance between the surgical techniques.Trial registrationwww.clinicaltrials.in.th (TCTR20200530003).

Long-term follow-up of patients treated with pyrocarbon disc implant for thumb carpometacarpal osteoarthritis: the effect of disc position on outcomes measures

Pyrocarbon disc interposition arthroplasty is an effective treatment for thumb base osteoarthritis. However, as with all implant techniques, the disc can (sub)luxate over time. The relationship between disc position, the experienced pain, and the necessity for revision surgery is not known. This study evaluated the effect of radiographic pyrocarbon disc position on the Michigan Hand Questionnaire (MHQ) outcome measurement. In addition, the correlation between disc position and other factors, including pain intensity, thumb strength, and occupation, was assessed. In this retrospective study, we included 136 patients (161 thumbs) with a mean follow-up of 6.7 years (range 3.3–11). Radiographs were scored on disc position and classified as ‘well aligned’ (Grade 1) up to ‘luxated’ (Grade 4). A database used for outcome measures included MHQ scores, pain intensity, satisfaction, thumb strength, range of motion, occupation, and hand dominance. In bivariate analyses, we assessed any association between disc position and outcome measurements. Eighty of the 136 implants (59%) were well-positioned (not displaced), 41% were (slightly) displaced (grade 2–3). No relationship existed between the degree of disc displacement and MHQ scores. Manual labor occupation was the only factor that correlated with more severe disc displacement. We could not detect any association between disc position and other outcome variables including pain intensity, thumb strength, or hand dominance. In conclusion, our study suggests that radiographic disc displacement has little clinical consequences. Future studies must assess if there is a causality between heavy mechanical stress to the CMC1 joint and luxation of the pyrocarbon disc over time. Level of evidence: IV Therapeutic—Retrospective case series.

Collagenase and the Treatment of Dupuytren Contracture: Efficacy of Treatment and Patient Satisfaction.

Background: Collagenase clostridium histolyticum has become a widely used treatment in the management of Dupuytren disease. The aims of this study are to assess the immediate success of treatment of Dupuytren contracture with collagenase injection, to measure long-term patient-rated outcomes, to determine whether the risk factors for the disease impacted outcomes and to report complications of collagenase treatment. Methods: A prospective study was performed in a tertiary referral centre. Measurements were recorded pre-treatment, day 1 and day 90. Patient-rated outcome scores were measured using Disability of the Arm, Shoulder and Hand questionnaire (DASH) and the Michigan Hand Questionnaire (MHQ) at minimum 36 months post-injection. Results: The study included 45 patients with 53 hands with a mean age of 65.7 years. The treatment was successful in 62% of patients with the greatest improvement in the metacarpal-phalangeal joint of the little finger. Diabetes, epilepsy, gender, alcohol intake and positive family history had no statistically significant predictive value on successful outcomes. Patient satisfaction at 41 months was high with mean MHQ score of 97.3. Conclusions: Collagenase is effective in the treatment of Dupuytren contracture, with disease involving the little finger showing the greatest benefit. Risk factors for development of Dupuytren disease had no effect on successful outcome and long-term satisfaction rates are high. Level of Evidence: Level III (Therapeutic).

Prescription Opioids and Patient-Reported Outcomes and Satisfaction After Carpal Tunnel Release Surgery.

Amount of opioid use correlates poorly with procedure-related pain; however, prescription limits raise concerns about inadequate pain control and impacts on patient-reported quality indicators. There remain no consistent guidelines for postoperative pain management after carpal tunnel release (CTR). We sought to understand how postoperative opioid use impacts patient-reported outcomes after CTR. This is a pragmatic cohort study using prospectively collected data from all adult patients undergoing uncomplicated primary CTR over 17 months at our center. Patients were categorized as having received or not received a postoperative opioid prescription, and then as remaining on a prescription opioid at 2-week follow-up or not. Questionnaires were completed before surgery and at 2-week follow-up. We collected brief Michigan Hand questionnaire (bMHQ) score, Patient-Reported Outcomes Measurement Information System Global Health score, satisfaction, and pain score. Of 505 included patients, 405 received a postoperative prescription and 67 continued use at 2-weeks. These 67 patients reported lower bMHQ, lower satisfaction, and higher postoperative pain compared to those that discontinued. Multivariable regressions showed that receiving postoperative prescriptions did not significantly influence outcomes or satisfaction. However, remaining on the prescription at 2 weeks was associated with significantly lower bMHQ scores, particularly in patients reporting less pain. Patients remaining on a prescription after CTR reported worse outcomes compared to those who discontinued. Unexpectedly, the widest bMHQ score gap was seen across patients reporting lowest pain scores. Further research into this high-risk subgroup is needed to guide policy around using pain and patient-reported outcomes as quality measures.Level of Evidence: Level III.

Does Use of a Night Extension Orthosis Improve Outcomes in Patients With Dupuytren Contracture Treated With Injectable Collagenase?

PurposeCurrent prescribing information for the treatment of patients with Dupuytren contracture with injectable collagenase Clostridium histolyticum (CCH) recommends use of a night extension orthosis for 4 months after treatment. The present study examines whether this treatment improves the outcomes.MethodsAdult patients with Dupuytren contracture treated with CCH during the study period were eligible for inclusion. The patients were randomized to orthosis or no orthosis groups and were stratified based on the severity of contracture prior to randomization. The orthosis group was fitted postmanipulation with a hand-based custom orthosis that held the treated finger in maximal comfortable extension, and the patients were instructed to wear the orthosis at night for 3 months. The patients were assessed at 7–10 days, 30 days, and 90 days postmanipulation. Orthosis compliance was measured with a survey. The primary outcome measure was improvement in total active extension (TAE), defined as the sum of active metacarpophalangeal (MCP), proximal interphalangeal, and distal interphalangeal joint extension in the treated finger at 90 days after treatment. Secondary outcomes included total active flexion (TAF), Michigan Hand Questionnaire scores, patient satisfaction, and clinical success.ResultsTwenty-six patients completed the study, 12 in the orthosis group and 14 in the no orthosis group. The majority of contractures (90%) were primarily through the MCP joint. The patients in both the groups demonstrated significant improvements in TAE at 90-day follow-up (orthosis P = .002, no orthosis P = .001) . The difference in improvement in the median TAE between the 2 groups was not significant (P = .40). There were no significant differences between groups for TAE, TAF, Michigan Hand Questionnaire scores, patient satisfaction, or clinical success at any of the time points assessed (P > .05).ConclusionsIn patients with Dupuytren contracture with primarily MCP joint involvement, providing an orthosis after treatment with CCH may not offer a short-term benefit compared with CCH treatment alone in terms of TAE, TAF, or patient-reported outcome measures.Type of study/level of evidenceTherapeutic I.

Early Wound Repair Versus Later Scar Repair in Children with Treadmill Hand Friction Burns.

The incidence of pediatric treadmill hand friction burns has been increasing every year. The injuries are deeper than thermal hand burns, the optimal treatment remains unclear. This was a retrospective study of children who received surgery for treadmill hand friction burns from January 1, 2015, to December 31, 2019, in a single burn center. A total of 22 children were surveyed. The patients were naturally divided into two groups: the wound repair group (13 patients), which was admitted early to the hospital after injury and received debridement and vacuum sealing drainage initially, and a full-thickness skin graft later; and the scar repair group (nine patients), in which a scar contracture developed as a result of wound healing and received scar release and skin grafting later. The Modified Michigan Hand Questionnaire score in the wound repair group was 116.31 ± 10.55, and the corresponding score in the scar repair group was 117.56 ± 8.85 (p > .05), no statistically significant difference. The Vancouver Scar Scale score in the wound repair group was 4.15 ± 1.21, and the corresponding score in the scar repair group was 7.22 ± 1.09 (p < .05). Parents were satisfied with the postoperative appearance and function of the hand. None in the two groups required secondary surgery. If the burns are deep second degree, third degree, or infected, early debridement, vacuum sealing drainage initially, and a full-thickness skin graft can obviously relieve pediatric pain, shorten the course of the disease, and restore the function of the hand as soon as possible.

Comparing digital replantation versus revision amputation patient reported outcomes for traumatic digital amputations of the hand: A systematic review and meta-analysis.

Adults with traumatic digital amputation (TDA) of the hand may be managed with replantation or revision amputation. To date, there is no systematic review evaluating patient reported outcomes (PROs) comparing replantation versus revision amputation. Three databases (MEDLINE, EMBASE, and PubMed) were systematically searched in duplicate from inception until June 13, 2019 using Covidence software. Studies comparing replantation versus revision amputation outcomes were considered for inclusion. Methodological quality was assessed using Methodologic Index for Nonrandomized Studies (MINORS) criteria. Data were pooled in a random-effects meta-analysis model using Revman software. Certainty of evidence was evaluated using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). Of 4350 studies identified, 12 retrospective cohort studies met inclusion criteria and compared TDA outcomes for replantation (n = 717; 82.9% male; mean age 40.3) versus revision amputation (n = 1046; 79.8% male; mean age 41.7). The overall replantation survival rate was 85.3%. The average MINORS score was 57% (13.75/24). Replantation of the thumb had a superior Michigan Hand Questionnaire (MHQ) score (+11.88, 95% CI [7.78-15.99], I2 = 21%) compared with revision amputation. Replantation of single non-thumb digits had a superior MHQ score (+5.31, 95% CI [3.10-7.51], I2 = 67%) and Disability of Arm, Shoulder, and Hand (DASH) score (-5.16, 95% CI [-8.27 to -2.06], I2 = 0%) compared with revision amputation. Most patients in the meta-analysis were from Asian populations (87.9%). There is low-quality evidence that thumb replantation achieves superior PROs compared with revision amputation, which may be clinically important. Replantation of single non-thumb digits also yielded superior PROs, which is likely not clinically important and based on very low-quality evidence. Future studies with populations outside Asia are required to determine if PROs vary based on cultural differences toward digital amputation.

Mid-term follow-up of surgically treated and healed scaphoid fractures

The aim of this study was to evaluate the mid-term results of surgically treated scaphoid fractures since we were concerned that good results might deteriorate over time due to osteoarthritis or functional impairment. Thirty-three out of 121 surgically treated patients (isolated scaphoid fractures n = 23; scaphoid fractures with concomitant injuries n = 10) were evaluated retrospectively (47–138 months). Five patients (4%) had a non-union after internal fixation and were excluded because of additional treatment. The remaining 83 patients were not available for a follow-up examination. Patients with an isolated scaphoid fracture had a mean extension-flexion of 68°–0°–64°, a radial-ulnar deviation of 27°–0°–41° and a grip strength of 39 kg (corresponding to 87–98% of the uninjured contralateral wrist), while patients with concomitant injuries had a mean extension-flexion of 60°–0°–44°, radial-ulnar deviation of 22°–0°–38° and a grip strength of 42 kg (corresponding to 73–98% of the uninjured contralateral wrist). The Michigan Hand Questionnaire score was 85 and 75 and the Patient-Rated Wrist Evaluation score was 8 and 21, respectively. Fifteen patients had radiological signs of radiocarpal osteoarthritis with a significantly higher occurrence in those who had concomitant injuries compared to those with isolated scaphoid fractures (p < 0.01). There was no significant group difference in scaphotrapeziotrapezoid (STT) osteoarthritis (p = 0.968). One STT osteoarthritis case occurred after plate fixation, one after antegrade screw fixation and 10 after retrograde screw fixation. Surgical treatment of an acute isolated scaphoid fracture has excellent clinical, functional, and radiologic mid-term results, while scaphoid fractures with concomitant wrist injuries have slightly inferior results.

Medium to Long-Term Follow-Up After Pyrocarbon Disc Interposition Arthroplasty for Treatment of CMC Thumb Joint Arthritis

Pyrocarbon disc interposition arthroplasty has been designed for the surgical treatment of Eaton-Glickel grade II/III carpometacarpal thumb joint arthritis. This study presents the results of this technique with a minimum 5-year follow up. We assessed 4 questionnaires for patient-reported outcome measurements in a cross-sectional study: the Patient-Rated Wrist and Hand Evaluation, Disabilities of Arm, Shoulder, and Hand questionnaire, Michigan Hand Questionnaire, and questions about satisfaction at the 5-year follow up. We evaluated grip and pinch strength, range of motion, and the radiological position of the disc. Finally, a Kaplan-Meier survival analysis was performed. A total of 164 thumbs (in 137 patients) were available for follow-up varying from 5 to 12 years. Median Patient-Rated Wrist and Hand Evaluation, Disabilities of Arm, Shoulder, and Hand, and Michigan Hand Questionnaire scores were 17, 18, and 76, respectively. The satisfaction score was 9 (Likert scale of 1-10). Grip and pinch strength reached nearly 100% compared with the contralateral hand. Range of motion resulted in a Kapandji score of 10. Thumb height showed a marginal loss and the Kaplan-Meier survival curve showed a survival rate of 91%. Our study suggests that pyrocarbon disc interposition arthroplasty is a reliable and feasible treatment for carpometacarpal thumb joint arthritis at medium-term follow-up. It was associated with a high level of patient satisfaction; it maintained thumb height and the implant survived in 91% of patients. Strength and range of motion were comparable to the contralateral hand after a minimum follow-up of 5 years. Therapeutic IV.

Translating the Strengthening and Stretching for Rheumatoid Arthritis of the Hand Programme from clinical trial to clinical practice: An effectiveness–implementation study

Introduction The Strengthening and Stretching for Rheumatoid Arthritis of the Hand programme is a hand exercise programme for people with rheumatoid arthritis. It was clinically effective when delivered during a clinical trial but there was a need to evaluate translation into routine care. Methods We conducted an effectiveness–implementation study. We adapted the trial training into an online format for National Health Service hand therapists. Educational outcomes included confidence and capability to deliver the programme. Implementation outcomes included training reach and adoption. Therapists were invited to collect clinical outcomes. Patients receiving the programme provided data on function (Michigan Hand Questionnaire function scale), pain and grip strength at baseline, treatment discharge and four-month follow-up. Results A total of 790 therapists (188 National Health Service organizations) enrolled in the training; 584/790 (74%) therapists (162 National Health Service organizations) completed the training; 448/790 therapists (145 National Health Service organizations) (57%) evaluated the training and were confident (447/448, 99.8%) and capable (443/448, 99%) to deliver the programme with 85% intending to adopt it (379/448). Follow-up data were provided by 116/448 (26%) therapists. Two-thirds (77/116; 51 National Health Service organizations) reported adopting the programme. One hundred and eighteen patients (15 National Health Service trusts) participated. Patients reported improved function (mean change Michigan Hand Questionnaire scores: 10 (95% CI 6.5–13.6) treatment discharge; 7 (95% CI 3.8–10.2) 4-month follow-up). Grip strength increased 24.5% (left) and 31% (right). Pain was stable. Discussion Online training was an effective way to train therapists with good reach. Clinical outcomes were similar to the clinical trial providing preliminary evidence of successful translation into routine care.

Esport Athletes' Quality Of Life Over A Professional Season

PURPOSE: Worldwide, video games have stormed into mainstream culture, creating a wave of opportunity for a new kind of athlete. In 2019, the global esports audience is expected to reach 453.8 million, while over 164 million adults in the United States now play video games and three-quarters of American households are home to at least one gamer. Few studies exist that address the unique set of health concerns in this growing population. Our objective was to monitor changes in health status over the 5-month competitive season among professional videogamers (n=6) from an esports team. METHODS: Data collection included Brief Michigan Hand Questionnaire (BMHQ), Patient Rated Outcomes Measurement Information System (PROMIS) measures, and physical exam measures. These measures were collected during the pre-participation physical exam in March and post-season August 2019. RESULTS: The mean age was 24 (range: 21-28 years); BMI was 28.8 kg/m2(range: 22.9-34 kg/m2); systolic blood pressure was 130 mmHg (range: 114-156 mmHg); diastolic blood pressure was 75 mmHg (range: 74-78 mmHg); pulse 92.5 bpm (range: 66-123 bpm), waist circumference was 91.75 cm (range: 77-106 cm). The mean post-season Quality of Life score (0.73) was lower than the mean pre-season score (0.80, p-value = 0.05). Global mental health, global physical health, physical function, upper extremity, and Brief Michigan Hand Questionnaire scores trended lower post-season, but did not reach statistical significance. Pain interference and pain intensity scores were higher post-season than the mean pre-season scores, but these differences were not statistically significant. CONCLUSIONS: This study identifies potential quality of life concerns associated with professional eAthletes. Further study is needed with a larger study population of professional eAthletes to confirm the physical and mental health changes over the course of a professional season. Findings may facilitate the development of injury prevention and treatment protocols to enhance the mental and physical health and wellness of eAthletes.
