Clubfoot from past to the present: A bibliometric analysis with global productivity and research trends.

Clubfoot, a common congenital abnormality, affects the lower extremities; however, the literature search revealed no bibliometric research on this subject. Thus, we aimed to holistically analyze scientific articles and reveal global productivity and trend issues. This study statistically analyzed 1417 published articles on clubfoot (1980-2021) from the Web of Science database. Bibliometric network visualization maps were created to reveal trend topics, citation analysis, and cross-country collaborations. The analysis was conducted using Spearman correlation analysis. An exponential smoothing estimator was used to predict article productivity. The United States of America (433, 30.5%), the United Kingdom (166, 11.7%), and India (107, 7.5%) are the top 3 countries contributing to the literature. The Journal of Pediatric Orthopedics (220 articles), the Journal of Pediatric Orthopedics-Part B (147 articles), and Clinical Orthopedics and Related Research (69 articles) are the top 3 most productive journals. Dobbs MB (34 articles) is the most active author, and Shriners Hospital Children (44 articles) is the most active institution. Bibliometric analysis revealed that recently studied trend topics included Pirani score, Dimeglio score, Ponseti method, Ponseti casting, tenotomy, recurrence, neglected, tendon transfer, bracing, gait, risk factors, pedobarography, complex clubfoot, and polymorphism. The most studied subjects included Ponseti technique, treatment/casting, recurrent/relapsed clubfoot, Pirani score, pediatrics/children, foot deformities, surgery, ultrasound, Achilles tendon/tenotomy, gait analysis, casting, outcomes, neglected clubfoot, and tenotomy. Research leadership was determined in the western and European countries and Canada in studies and scientific collaborations on clubfoot; its impact was remarkable in India, China, and Turkey.

Emerging Treatment Options for Chronic Tendinopathy of the Foot: A Clinical Vignette.

ABSTRACT: The patient is a 65-year-old female recreational skier and avid walker who presented with a several-month history of right ankle and foot pain. The patient's pain began without inciting event and was described as a constant aching pain aggravated by downhill walking and alleviated with rest. She was diagnosed with right distal tibialis anterior tendinopathy with partial thickness tear noted on magnetic resonance imaging and musculoskeletal ultrasound. Given symptoms recalcitrant to conservative measures, the patient opted to pursue an ultrasound-guided prolotherapy injection and a course of physical therapy; unfortunately, she did not have any improvement in symptoms. The patient subsequently underwent ultrasound-guided percutaneous ultrasonic tenotomy and debridement of the distal tibialis anterior tendon, followed by a postprocedure rehabilitation protocol of physical therapy with transition to home exercise program with complete resolution of her pain. Prolotherapy, and percutaneous ultrasonic tenotomy and debridement are two treatment modalities that show promise in the treatment of painful, chronic tendinopathy.

Medial Elbow Pain Syndrome: Current Treatment Strategies.

Medial elbow pain is a common presentation that can be a challenge to appropriately treat for the orthopedic surgeon. Causes include medial epicondylitis, ulnar neuritis, ulnar collateral ligament injury, flexor pronator strain, or snapping medial triceps. A good outcome is typically achieved with adequate treatment of tendon degeneration at the common flexor tendon origin. Mainstay treatment is nonoperative modalities such as stretching, rest, activity modification, therapy, and injections. If nonoperative management fails, intermediate interventions such as extracorporeal shockwave therapy, platelet-rich plasma injections, prolotherapy, and ultrasound-guided percutaneous tenotomy can be attempted. Surgical treatments are dictated based on the severity of the pathology, involvement of soft tissues, and concomitant pathology. Medial elbow complaints can be multifactorial and require a broad differential diagnosis. [Orthopedics. 2023;46(2):e81-e88.].

Quantification of Procedure Time and Infant Distress Produced (as Crying) When Percutaneous Achilles Tenotomy Is Performed under Topical Local Anaesthesia: A Preliminary Study.

INTRODUCTION: Percutaneous tenotomy of the Achilles tendon is part of the clubfoot management procedure known as the Ponseti method and is necessary for most infants requiring this treatment. However, the need to apply general anaesthesia or sedation during this procedure remains controversial. To our knowledge, no previous studies have been conducted to quantify infant distress, expressed as crying, when tenotomy is performed under local anaesthesia. MATERIAL AND METHODS: This clinical, prospective, cross-sectional, and observational study was composed of infants subjected to percutaneous Achilles tenotomy with local anaesthesia at an outpatient clinic. The degree of distress was measured using two smartphone apps (voice recorder and timer) in two iPhones, with each apparatus placed one meter from the baby. The following parameters were determined: procedure duration, crying duration, average crying intensity and maximum crying intensity. In addition, the following data were obtained: age, complications (if any) and the caregiver's satisfaction with the process. RESULTS: Among the 85 infants submitted to percutaneous tenotomy, the mean age was 1.95 (+/-1.632) months (ranging from 0 to 7 months), the mean duration of the procedure was 8.134 (+/-5.97) seconds, (range 2.1 to 33.5 s), the infants' mean crying intensity was 88.99 dB and the maximum crying intensity was 96.56 dB. No vascular or anaesthetic-related complications were recorded. 96% of the caregivers were absolutely satisfied with the process. CONCLUSIONS: Percutaneous Achilles tenotomy performed under local anaesthesia can safely be performed at the outpatient clinic. The procedure is fast and the crying time and intensity (mean values: 84 s and 89 dB, respectively) are minimal and tolerable. Knowledge of these parameters provides more accurate knowledge about the procedure. The caregivers consulted were absolutely satisfied with the tenotomy performed under local anaesthesia. In future studies, these parameters can be used for comparison with related surgical approaches.

Ultrasound-guided Procedures Allow Delay of Definitive Treatment for Core Muscle Injuries.

INTRODUCTION: Core muscle injuries (CMI) are common in every sport. To minimize lost playing time, providers apply various nonsurgical treatments, including platelet-rich plasma, corticosteroids, ultrasound (US)-guided percutaneous tenotomy, and prolotherapy. Limited data exist with regard to their effectiveness. We chose to review a cohort of consecutive professional and collegiate athletes who sustained CMI at various points within their seasons and underwent a combination of US-guided percutaneous needle "tenotomy" and corticosteroid injections to complete the remainder of their seasons. METHODS: Twenty-five consecutive collegiate or professional athletes with CMI involving the rectus abdominis-adductor aponeurotic plate were included in this retrospective study. Athletes with concomitant symptomatic hip femoroacetabular impingement were included in the study. The primary outcome measure was whether athletes completed their seasons. Secondary measures were weeks played after the procedures (delay until surgery), need for repeat procedures, and outcomes after eventual surgery. Postoperative performance was assessed via interviews at 6 wk and 6 months postoperatively. RESULTS: Twenty-one of 25 (84%) athletes completed their seasons. On average, athletes returned to play 3 d (range, 1-9 d) after the procedures. Surgical repair was delayed a mean of 18 wk (range, 2-44 wk). Seven athletes had concomitant symptomatic femoroacetabular impingement and six underwent combined hip arthroscopy and core muscle repairs. Among 17 patients who eventually had core muscle surgery alone (no hip surgery), 82% (14 of 17) reported performing at their preinjury level at 6 wk. At 6 months, 96% of postop athletes (22 of 23) reported performing at their preinjury level. CONCLUSIONS: Temporizing CMI with US-guided percutaneous tenotomy and corticosteroid injections is effective in allowing continued sport participation among high-level athletes and does not negatively affect postoperative outcomes.

Aponeurotic release of semimembranosus: A technical note to increase correction gained with hamstring lengthening surgery in cerebral palsy.

OBJECTIVE: The aim of this study was to determine the intraoperative corrective effect of the aponeurotic release of semimembranosus (SM) as a single procedure or an adjunct procedure to distal myotendinous release of semitendinosus (ST) and myofascial release of SM lengthening in the correction of knee flexion deformity in cerebral palsy (CP). METHODS: In this prospective study, 46 knees of 23 consecutive ambulatory patients (15 boys and 8 girls; mean age=8.33 years; age range=5-12 years) with spastic diplegic CP with a gross motor function classification system level (GMFCS) II or III were included. The patients were then divided into 2 groups. In group I, there were 10 patients (4 boys, 6 girls; mean age=8.6±2), and combined release of ST in the myotendinous junction and SM in the myofascial junction, followed by aponeurotic release of SM were carried out. In group II, there were 13 patients (2 girls, 11 boys; mean age=8±2.35), and aponeurotic release of SM was done first and followed by the combined release of ST in the distal myotendinous junction and the myofascial release of SM. Intraoperative popliteal angle (PA) measurements were recorded in each group. RESULTS: PA was reduced from 58.1°±7.6° (range=46°-75°) to 41.2°±8.8° (range=20°-54°) in group 1 and from 59.1°±11.3° (range=40°-87°) to 42.7°±10.8° (range=24°-64°) in group 2. No significant difference was observed between the groups in terms of reduction in PA (p=0.867). In group 1, adding the aponeurotic release of SM further reduced the PA to 31.7°± 8.5° (range=14°-47°) (p=0.002). In group 2, adding the myotendinous release of ST and myofascial release of SM further reduced the PA to 32.9°±7.2° (range=16°-44°) (p=0.004). There was no significant difference between the final PA values in the 2 groups (p=0.662). There was no difference in terms of early complications. CONCLUSION: Aponeurotic release of SM is equally effective to reduce the intraoperative PA with combined myotendinous release of ST and myofascial release of SM. Combining all the 3 procedures provides a better correction without forceful manipulation or lengthening of the lateral hamstrings during the correction of knee flexion deformity in CP.

[Selective ultrasound-guided hydrodissection of gastrocnemius nerve branch after post-surgical entrapment: Apropos of a case]. / Hidrodisección ecoguiada selectiva de rama nerviosa gemelar tras atrapamiento posquirúrgico: a propósito de un caso.

Chronic or recalcitrant plantar fasciitis is a cause of persistent plantar pain. These cases are usually resistant to conventional treatments consisting of exercises, orthoses, shock waves and infiltrations and require a surgical approach. Proximal medial gastrocnemius release is a surgical option that provides satisfactory results, but is not free of complications, which include injuries and nerve entrapment. We report the first published case of symptomatic medial gastrocnemius branch entrapment in the post-surgical scar of a tenotomy for the treatment of recalcitrant plantar fasciitis. We propose ultrasound-guided hydrodissection with local anesthetic as a treatment with promising results.

Effect of low intensity photobiomodulation associated with norbixin-based poly (hydroxybutyrate) membrane on post-tenotomy tendon repair. In vivo study.

PURPOSE: To evaluate the in vivo response of photobiomodulation therapy associated with norbixin-based poly(hydroxybutyrate) membrane (PHB) in tenotomized calcaneal tendon. METHODS: Thirty rats were randomly allocated to six groups (n=5 each): LED groups (L1, L2 and L3) and membrane + LED groups (ML1, ML2 and ML3). The right calcaneal tendons of all animals were sectioned transversely and were irradiated with LED daily, one hour after surgery every 24 hours, until the day of euthanasia. At the end of the experiments the tendons were removed for histological analysis. RESULTS: The histological analysis showed a significant reduction in inflammatory cells in the ML1, ML2 and ML3 groups (p=0.0056, p=0.0018 and p<0.0001, respectively) compared to those in the LED group. There was greater proliferation of fibroblasts in the ML1 (p<0.0001) and L3 (p<0.0001) groups. A higher concentration of type I collagen was also observed in the ML1 group (p=0.0043) replacing type III collagen. CONCLUSION: Photobiomodulation in association with norbixin-based PHB membrane led to control of the inflammatory process. However, it did not favor fibroblast proliferation and did not optimize type I collagen formation in the expected stage of the repair process.

Clinical indications for image-guided interventional procedures in the musculoskeletal system: a Delphi-based consensus paper from the European Society of Musculoskeletal Radiology (ESSR)-Part II, elbow and wrist.

BACKGROUND: Although image-guided interventional procedures of the elbow and wrist are routinely performed, there is poor evidence in the literature concerning such treatments. Our aim was to perform a Delphi-based consensus on published evidence on image-guided interventional procedures around the elbow and wrist and provide clinical indications on this topic. METHODS: A board of 45 experts in image-guided interventional musculoskeletal procedures from the European Society of Musculoskeletal Radiology were involved in this Delphi-based consensus study. All panelists reviewed and scored published papers on image-guided interventional procedures around the elbow and wrist updated to September 2018 according to the Oxford Centre for Evidence-based Medicine levels of evidence. Consensus on statements drafted by the panelists about clinical indications was considered as "strong" when more than 95% of panelists agreed and as "broad" if more than 80% agreed. RESULTS: Eighteen statements were drafted, 12 about tendon procedures and 6 about intra-articular procedures. Only statement #15 reached the highest level of evidence (ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement). Seventeen statements received strong consensus (94%), while one received broad consensus (6%). CONCLUSIONS: There is still poor evidence in published papers on image-guided interventional procedures around the elbow and wrist. A strong consensus has been achieved in 17/18 (94%) statements provided by the panel on clinical indications. Large prospective randomized trials are needed to better define the role of these procedures in clinical practice. KEY POINTS: • The panel provided 18 evidence-based statements on clinical indications of image-guided interventional procedures around the elbow and wrist. • Only statement #15 reached the highest level of evidence: ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement. • Seventeen statements received strong consensus (94%), while broad consensus was obtained by 1 statement (6%).

Minimally Invasive and Endoscopic Approach for the Treatment of Noninsertional Achilles Tendinopathy.

Minimally invasive treatment can offer an earlier recovery with less pain and scarring compared with traditional open surgeries. The goals of minimally invasive surgery are to debride degenerative tendon, stimulate healing, and, when appropriate, repair damaged tendon. Sclerotherapy and prolotherapy have been shown to reduce neovascularization and pain. Percutaneous stripping and endoscopic debridement are better options for diffuse tendinopathy. Plantaris release can be useful in diffuse disease in patients with primarily medial-sided Achilles pain. Overall, minimally invasive surgery provides similar benefits as open procedures with reduced complications and morbidity.

Magnolol prevents ossified tendinopathy by inhibiting PGE2-induced osteogenic differentiation of TDSCs.

Magnolol is a compound that is extracted from magnolia, is used in Chinese medicine and is a type of lignan. Magnolol has various anti-inflammation, anti-proliferation and pro-autophagy effects. Ossified tendinopathy affects many athletes and people with repetitive tendon injuries. Ossified tendinopathy is a tremendous economic burden, and no effective and safe drugs are available to prevent the pathogenesis of ectopic ossification. In this study, we aimed to study how magnolol affects ossified tendinopathy by evaluating its effects on osteogenic differentiation of tendon-derived stem cells (TDSCs). Our data suggested that magnolol attenuated ectopic ossification in the Achilles tendon caused by Achilles tenotomy. Magnolol inhibited PGE2-induced ALP activity and prevented calcium deposits in TDSCs in vitro. Magnolol also exerted inhibitory effects on expression of osteogenic factors, such as Runx2, OCN, and BMP2 in vivo. Further investigation revealed the underlying mechanism by which magnolol prevents PGE2-induced ectopic ossification. Specifically, magnolol inhibits PGE2-induced PI3K/AKT/ß-catenin pathway activation in TDSCs. Our findings demonstrated that magnolol inhibited ossified tendinopathy through preventing osteogenic differentiation of TDSCs via downregulation PGE2-induced PI3K/AKT/ß-catenin pathways.

Percutaneous achillotomy in the treatment of congenital clubfoot: should it be performed in the operating theater or the polyclinic?

BACKGROUND: The aim of this study was to compare the efficacy, advantages, and complications of percutaneous achillotomy in the treatment of clubfoot with the Ponseti method when performed to two different groups under general anesthesia or polyclinic conditions with local anesthesia. METHODS: A retrospective evaluation was made of 96 patients treated for clubfoot in our clinic between January 2013 and June 2016. Fifty-seven patients were separated into two groups according to whether the achillotomy was performed in polyclinic conditions with local anesthesia or under general anesthesia following serial plaster casting with the Ponseti method. RESULTS: The characteristics of age distribution, mean week of tenotomy, side, and sex were similar in both groups. No statistically significant difference was determined between the two groups in respect to complication and recurrence. The durations of hospitalization-observation, separation from the mother, and fasting were found to be statistically significantly shorter in local anesthesia group. CONCLUSION: Although the performance of percutaneous achillotomy with local or general anesthesia has different advantages, it can be considered that especially in centers with high patient circulation, achillotomy with local anesthesia can be more preferable to general anesthesia because it is practical and quick, does not require a long period of fasting or hospitalization, and has a similar complication rate to general anesthesia procedures.

Effects of the essential oil of Alpinia zerumbet (Pers.) B.L. Burtt & R.M. Sm. on healing and tissue repair after partial Achilles tenotomy in rats.

PURPOSE:: To investigate the cellular response to injury, analyzing histopathologic changes associated with increased cellularity, degeneration and disorganization of collagen fibers. METHODS:: Thirty wistar rats were divided in two groups after partial Achilles tenotomy: the right hind paw were treated with the essential oil of Alpinia zerumbet (EOAz), diluted to 33% (0.3 mL kg-1), and the left hind paw received sunflower oil for 3, 14, 30 and 90 days. Statistical significance was determined using a Chi-square and Pearson Correlation qualitative variables test. Moreover, Mann-Whitney U-test test for comparison between different groups of the same cell, one-way ANOVA, and Tukey's test of quantitative measurement. RESULTS:: A decrease hyperemia (p < 0.001) was observed in the acute phase of inflammatory cell number (p < 0.001), whereas sub-acute phase was marked by significant correlation with macrophages in fibroblasts (r = 0.17, p = 0.03), with probable induction a dense and modeled tissue. At chronic phase, it was found an increase in the number of fibroblasts and a higher percentage of type I collagen fibers (78%) compared with control collagen fibers (55%). CONCLUSION:: Oil of Alpinia zerumbet stimulated the process of maturation, organization and tissue repair which gave it greater resistance.

Wide-awake ultrasound-guided percutaneous extensor central slip tenotomy for chronic mallet finger: A prospective study of 14 cases (with videos).

The central slip tenotomy described by Fowler is an effective option for treating chronic mallet finger in order to avoid swan neck deformity of the finger. In a prospective study of 14 cases (13 failures of conservative treatment and one case of untreated mallet finger), we performed percutaneous ultrasound-guided central slip tenotomy with a 19 G needle using the wide-awake local anesthesia and no tourniquet (WALANT) technique. The mean extensor lag before surgery was 28° (range 20°-40°) and three patients had a swan neck deformity. The anesthesia and tenotomy were guided with a 15MHz high frequency probe. Patient were asked to grade their pain between 0 (no pain) and 10 (extreme pain) with a Visual Analog Scale (VAS), to flex and extend their finger immediately after the tenotomy and to be reviewed at 1month's follow-up. The mean pain score on VAS during the procedure was 1/10 (range 0-3). After several movements of the finger after the procedure, two patients immediately regained full extension of the distal interphalangeal joint. At 1month follow-up, the correction was complete for 10 patients, three patients had a residual deformity of 10° and one had a poor result with a 30° deformity. Two patients had a persistent painless synovitis of the proximal interphalangeal joint. Thirteen patients were fully satisfied and one was a disappointed, but did not want another treatment. There are no published reports of percutaneous central slip tenotomy. In this preliminary report, central slip tenotomy for chronic mallet finger with ultrasonography was painless, effective and safe under WALANT technique. Larger clinical studies are needed to confirm the outcomes of this study.

Treatment of Massive Irreparable Rotator Cuff Tears: A Cost-effectiveness Analysis.

Massive irreparable rotator cuff tears cause significant shoulder pain and dysfunction. Physical therapy (PT), arthroscopic debridement with biceps tenotomy (AD-BT), and hemiarthroplasty (HA) are treatments shown to reduce pain and improve quality of life. Reverse total shoulder arthroplasty (RTSA) is a newer surgical treatment option that may offer improved function. A cost-effectiveness analysis of these interventions has never been performed, and no head-to-head comparative effectiveness trials currently exist. A Markov decision analytic model was used to compare RTSA, HA, AD-BT, and PT as treatments for elderly patients with massive irreparable rotator cuff tears. Probabilities for complications, perioperative death, conversion procedures, and reoperations were derived from the literature, and costs were determined by average Medicare reimbursement rates from 2011. Reverse total shoulder arthroplasty yielded the most quality-adjusted life years (QALY) with 7.69, but greater benefits came at higher costs compared with other treatments. Sensitivity analyses showed that PT was the most cost-effective intervention at a health utility of 0.75 or greater (QALY 7.35). The health utility of RTSA was 0.72 or less (QALY 7.48) or RTSA probability of no complications was 0.83 or less (QALY 7.48 at cost of $23,830). Reverse total shoulder arthroplasty yielded benefits at a cost considered good value for money compared with other treatments. Reverse total shoulder arthroplasty is the preferred and most cost-effective treatment option for elderly patients with massive irreparable rotator cuff tears. For patients seeking pain relief without functional gains, AD-BT can be considered a cost-effective and cheaper alternative. The cost-effectiveness analysis approach can help guide clinical practice as well as the policies of health care systems and insurers. [Orthopedics. 2017; 40(1):e65-e76.].

Ultrasound-Guided Percutaneous Tendon Treatments.

OBJECTIVE: The purpose of this article is to review currently available tendon treatments, especially those performed with sonographic guidance. CONCLUSION: Treatments of tendon disease have continued to develop and expand, and multiple therapeutic options have become available, all with varying levels of supportive clinical evidence of their efficacy. The use of ultrasound to direct these treatments improves accuracy and performance by facilitating visualization of the target and relevant adjacent structures.

Low-level laser therapy modulates pro-inflammatory cytokines after partial tenotomy.

Tendon injuries give rise to substantial morbidity, and current understanding of the mechanisms involved in tendon injury and repair is limited. This lesion remains a clinical issue because the injury site becomes a region with a high incidence of recurrent rupture and has drawn the attention of researchers. We already demonstrated that low-level laser therapy (LLLT) stimulates the synthesis and organization of collagen I, MMP-9, and MMP-2 and improved the gait recovery of the treated animals. The aim of this study was to evaluate the effects of LLLT in the nitric oxide and cytokines profile during the inflammatory and remodeling phases. Adult male rats were divided into the following groups: G1--intact, G2-- injured, G3--injured + LLLT (4 J/cm(2) continuous), G4--injured + LLLT (4 J/cm(2)-20 Hz--pulsed laser). According to the analysis, the animals were euthanized on different dates (1, 4, 8, or 15 days after injury). ELISA assay of TNF-α, IL-1ß, IL-10, and TGF-ß was performed. Western blotting of isoform of nitric oxide synthase (i-NOS) and nitric oxide dosage experiments was conducted. Our results showed that the pulsed LLLT seems to exert an anti-inflammatory effect over injured tendons, with reduction of the release of proinflammatory cytokines, such as TNF-α and the decrease in the i-NOS activity. Thanks to the pain reduction and the facilitation of movement, there was a stimulation in the TGF-ß and IL-1ß release. In conclusion, we believe that pulsed LLLT worked effectively as a therapy to reestablish the tendon integrity after rupture.

Outcome of Percutaneous Tenotomy in the Management of Congenital Talipes Equino Varus by Ponseti Method.

Congenital talipes equino varus (CTEV) is a common complex congenital anomaly affecting approximately 1 per 900 live births in Bangladesh. Current trends in the treatment of idiopathic clubfoot have shifted from extensive surgical release to more conservative techniques. The Ponseti method that includes manipulation, serial casting, percutaneous tenotomy and bracing has recently become very popular for the management of CTEV with reported excellent outcomes. The purpose of this study was to evaluate the outcomes of Percutaneous Tenotomy in the treatment of equinus deformity of idiopathic clubfoot. Between June 2012 and November 2013 we treated 47 feet in 34 children by the Ponseti method. The standard protocol described by Ponseti was used. Percutaneous tenotomy of the Achilles tendon was performed under local anaesthesia in the outpatient department of Dhaka Medical College Hospital. The Pirani score was used for assessment and mean follow up time was 12 months. The compliance of percutaneous tenotomy among the 47 feet was recorded and 40(85.1%) were good, 4(8.5%) were fair and 3(6.4%) were poor. The rating of final outcome of percutaneous tenotomy after one year follow-up periods among 47 feet, 36(76.6%) were good, 11(23.4%) were fair and zero (0%) were poor. This study permits to conclude the percutaneous tenotomy in Ponseti method as a safe, effective outdoor procedure to correct the residual equinus deformity of club foot after serial casting.
