Patient-directed follow-up for the clinical scaphoid fracture.

Aims: Occult (clinical) injuries represent 15% of all scaphoid fractures, posing significant challenges to the clinician. MRI has been suggested as the gold standard for diagnosis, but remains expensive, time-consuming, and is in high demand. Conventional management with immobilization and serial radiography typically results in multiple follow-up attendances to clinic, radiation exposure, and delays return to work. Suboptimal management can result in significant disability and, frequently, litigation. Methods: We present a service evaluation report following the introduction of a quality-improvement themed, streamlined, clinical scaphoid pathway. Patients are offered a removable wrist splint with verbal and written instructions to remove it two weeks following injury, for self-assessment. The persistence of pain is the patient's guide to 'opt-in' and to self-refer for a follow-up appointment with a senior emergency physician. On confirmation of ongoing signs of clinical scaphoid injury, an urgent outpatient 'fast'-wrist protocol MRI scan is ordered, with instructions to maintain wrist immobilization. Patients with positive scan results are referred for specialist orthopaedic assessment via a virtual fracture clinic. Results: From February 2018 to January 2019, there were 442 patients diagnosed as clinical scaphoid fractures. 122 patients (28%) self-referred back to the emergency department at two weeks. Following clinical review, 53 patients were discharged; MRI was booked for 69 patients (16%). Overall, six patients (< 2% of total; 10% of those scanned) had positive scans for a scaphoid fracture. There were no known missed fractures, long-term non-unions or malunions resulting from this pathway. Costs were saved by avoiding face-to-face clinical review and MRI scanning. Conclusion: A patient-focused opt-in approach is safe and effective to managing the suspected occult (clinical) scaphoid fracture.

Management of de Quervain Tenosynovitis: A Systematic Review and Network Meta-Analysis.

Importance: There is a plethora of treatment options for patients with de Quervain tenosynovitis (DQT), but there are limited data on their effectiveness and no definitive management guidelines. Objective: To assess and compare the effectiveness associated with available treatment options for DQT to guide musculoskeletal practitioners and inform guidelines. Data Sources: Medline, Embase, PubMed, Cochrane Central, Scopus, OpenGrey.eu, and WorldCat.org were searched for published studies, and the World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, The European Union Clinical Trials Register, and the ISRCTN registry were searched for unpublished and ongoing studies from inception to August 2022. Study Selection: All randomized clinical trials assessing the effectiveness of any intervention for the management of DQT. Data Extraction and Synthesis: This study was prospectively registered on PROSPERO and conducted and reported per Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-analyses of Health Care Interventions (PRISMA-NMA) and PRISMA in Exercise, Rehabilitation, Sport Medicine and Sports Science (PERSIST) guidance. The Cochrane Risk of Bias tool and the Grading of Recommendations, Assessment, Development, and Evaluations tool were used for risk of bias and certainty of evidence assessment for each outcome. Main Outcomes and Measures: Pairwise and network meta-analyses were performed for patient-reported pain using a visual analogue scale (VAS) and for function using the quick disabilities of the arm, shoulder, and hand (Q-DASH) scale. Mean differences (MD) with their 95% CIs were calculated for the pairwise meta-analyses. Results: A total of 30 studies with 1663 patients (mean [SD] age, 46 [7] years; 80% female) were included, of which 19 studies were included in quantitative analyses. From the pairwise meta-analyses, based on evidence of moderate certainty, adding thumb spica immobilization for 3 to 4 weeks to a corticosteroid injection (CSI) was associated with statistically but not clinically significant functional benefits in the short-term (MD, 10.5 [95% CI, 6.8-14.1] points) and mid-term (MD, 9.4 [95% CI, 7.0-11.9] points). In the network meta-analysis, interventions that included ultrasonography-guided CSI ranked at the top for pain. CSI with thumb spica immobilization had the highest probability of being the most effective intervention for short- and mid-term function. Conclusions and Relevance: This network meta-analysis found that adding a short period of thumb spica immobilization to CSI was associated with statistically but not clinically significant short- and mid-term benefits. These findings suggest that administration of CSI followed by 3 to 4 weeks immobilization should be considered as a first-line treatment for patients with DQT.

Proximal Interphalangeal Joint Arthroplasty Using the Wide-Awake Local Anesthesia No Tourniquet Technique.

BACKGROUND: Proximal interphalangeal joint (PIPJ) osteoarthritis is a common condition that results in pain, stiffness, and loss of function in the affected hand. Proximal interphalangeal joint arthroplasty is an effective treatment option when conservative methods have failed. The wide-awake local anesthesia no tourniquet (WALANT) technique to perform surgery carries advantages such as lack of tourniquet discomfort, reduces the staffing and costs associated with anesthesia and sedation, and allows faster recovery. We aimed to determine whether the WALANT technique was safe and effective in the context of PIPJ arthroplasty. METHODS: Patients were enrolled retrospectively from January 2015 to October 2020 by examining operating theater records and surgeon logbooks. Electronic patient records were examined to obtain patient data. Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaires and Visual Analog Scale (VAS) for pain were sent by post to patients-with a separate DASH and VAS for each digit operated on. RESULTS: Twenty-nine PIPJ arthroplasties were carried out using WALANT technique by 3 different surgeons all using the dorsal approach. All cases were successfully carried out as day-case procedures. There was a significant correlation with increasing VAS and increasing DASH score. Proximal interphalangeal joint arthroplasty improved range of motion from 28.9 ± 5.5° to 79.4 ± 13.3° (P < .0001). Two cases developed complications related to surgery. CONCLUSIONS: Our study is the first to report the use of WALANT to perform PIPJ arthroplasty, and shows comparable results with traditional methods. Larger, multicenter prospective trials are required to determine the efficacy of this technique and to quantify its economical benefit.

A Meta-analysis of Surgical Interventions for Base of Thumb Arthritis.

Background There is a myriad of available surgical options for thumb carpometacarpal joint (CMCJ) arthritis and no robust evidence exists to guide the decisions of treating surgeons. Our aim was to assess the comparative effectiveness of different surgical interventions available for the treatment of thumb CMCJ arthritis. Methods We performed a systematic review, pairwise, and network meta-analysis of all randomized studies comparing surgical interventions for thumb CMCJ arthritis. Our primary outcomes were pain, function, and key pinch strength at long-term follow-up (> 6 months). Risk of bias and certainty of evidence were assessed for each outcome measure of compared interventions separately. Clinical recommendations were based on evidence of strong or moderate certainty. Results A total of 17 randomized studies were included in the systematic review. Where possible, pairwise and network meta-analyses were performed. Based on evidence of moderate certainty, trapeziectomy with a concomitant ligament reconstruction and tendon interposition (LRTI) does not appear to be associated with any long-term clinical benefits compared with simple trapeziectomy (function: mean difference [MD] -3.72 [-9.15, 1.71], p = 0.64 favoring simple trapeziectomy; key pinch strength: MD 0.07 kg [-0.28, 0.43], p = 0.68 favoring trapeziectomy with LRTI). Treatment rankings from the network meta-analysis favored trapeziectomy with and without LRTI, joint replacement, and arthrodesis. Trapeziectomy with LRTI appears to be associated with fewer major complications compared with joint replacement and arthrodesis, and more minor complications compared with simple trapeziectomy. Conclusion Until further high-quality research indicates otherwise, simple trapeziectomy should be the preferred surgical modality for base of the thumb arthritis. Level of Evidence This is a Level 1 study.

Effectiveness of Sodium Hyaluronate and ADCON-T/N for the Prevention of Adhesions in Hand Flexor Tendon Surgery: A Systematic Review and Meta-Analysis.

PURPOSE: A common complication after digital flexor tendon repair in the hand is postoperative adhesions that can cause loss of motion and compromise hand function. The aim of this review of relevant published literature was to assess the effectiveness of locally administered sodium hyaluronate or ADCON-T/N for the prevention of adhesions after hand flexor tendon repair. METHODS: A literature search was conducted in June 2020 in multiple databases for randomized controlled trials . Our primary outcome was measurement of active finger motion. Follow-up was defined as short-term (< 12 weeks), mid-term (12 weeks to 6 months) and long-term (> 6 months). Mean differences (MD) and standardized mean differences (SMD) of total active motion (TAM) of the interphalangeal joints (IPJs) and active motion of the IPJs separately were calculated where results were meta-analyzed. RESULTS: Six randomized controlled trials were included. For ADCON-T/N, no benefits were detected for TAM of the IPJs (MD 1.71 [-21.54, 24.96]) or active motion of the IPJs separately (proximal: MD 4.77 [-4.47, 14]; distal: MD 1.17 [-10.33, 12.66]) in the short-/mid-term. The mid-term benefit in TAM of sodium hyaluronate over standard care (placebo/no treatment) did not reach statistical significance (SMD 0.31 [0, 0.63]); however, a subgroup comparison of repeated administration of sodium hyaluronate versus standard care was both statistically and clinically significant (SMD 0.55 [0.11, 0.98]). CONCLUSIONS: Repeated administration of sodium hyaluronate at the tendon repair site may be effective in improving postoperative active finger motion after primary hand flexor tendon repair in the mid-term. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Risk of periprosthetic fracture after anterior femoral notching.

BACKGROUND: Notching of the anterior femoral cortex in distal femoral fractures following TKR has been observed clinically and studied biomechanically. It has been hypothesized that femoral notching weakens the cortex of the femur, which can predispose to femoral fractures in the early postoperative period. We examined the relationship between notching of the anterior femoral cortex during total knee replacement (TKR) and supracondylar fracture. PATIENTS AND METHODS: Postoperative lateral radiographs of 200 TKRs were reviewed at an average of 9 (6-15) years postoperatively. 72 knees (41%) showed notching of the anterior femoral cortex. Notches were classified into 4 grades using the Tayside classification as follows. Grade I: violation of the outer table of the anterior femoral cortex; grade II: violation of the outer and the inner table of the anterior femoral cortex; grade III: violation up to 25% of the medullary canal (from the inner table to the center of the medullary canal); grade IV: violation up to 50% of the medullary canal (from the inner table to the center of the medullary canal) and unclassifiable. RESULTS: The interobserver variability of the classification system using Cohen's Kappa score was found to be substantially reliable. 3 of the 200 TKRs sustained later supracondylar fractures. One of these patients had grade II femoral notching and the other 2 showed no notching. The patient with femoral notching sustained a supracondylar fracture of the femur following a simple fall at home 9 years after TKR. INTERPRETATION: There is no relationship between minimal anterior femoral notching and supracondylar fracture of the femur in TKR.

Locked intramedullary nailing versus dynamic compression plating for humeral shaft fractures.

PURPOSE. To compare functional outcomes, union and complication rates in patients treated with locked intramedullary nailing or dynamic compression plating for humeral shaft fractures. METHODS. 32 men and 2 women with humeral shaft fractures were randomised to undergo locked antegrade intramedullary nailing (IMN, n=16) or dynamic compression plating (DCP, n=18). Patients with pathological fractures, grade-III open fractures, neurovascular injury, or fractures for more than 2 weeks were excluded. Fractures were classified according to the AO classification system (one in A1, 6 in A2, 12 in A3, 6 in B1, and 9 in B2). 28 were injured in road traffic accidents. The functional outcome (according to the American Shoulder and Elbow Surgeons [ASES] score) and rates of union and complication of the 2 groups were compared. RESULTS. All patients were followed up for a minimum of 24 months. In the respective IMN and DCP groups, the mean ASES scores were 45.2 and 45.1 (p=0.69), the complication rates were 50% and 17% (p=0.038), and the non-union rates were 0% and 6% (p=0.15). In the IMN group, 2 sustained iatrogenic fractures during nail insertion; 2 had transient radial nerve palsies; one underwent nail removal for shoulder impingement; and 3 had adhesive capsulitis. In the DCP group, one underwent re-operation for implant failure; one had a superficial infection; and one developed adhesive capsulitis. CONCLUSION. The complication rate was higher in the IMN group, whereas functional outcomes were good with both modalities.
