Flexor tenotomy has been recommended to assist in the healing of pre-ulcerative or ulcerative lesions with generally high rates of healing, although variable rates of complications have been reported. This study aimed to evaluate the safety, efficacy, and outcomes of flexor tenotomy for the treatment of pre-ulcerative and ulcerative digital lesions.MethodsA retrospective chart review was performed for patients who underwent percutaneous flexor tenotomy for treatment of digital ulcerations or pre-ulcerative lesions from January 2020 to January 2023. Outcomes assessed included healing of the index lesion and complications after tenotomy. Univariate analysis was performed to assess associations between clinical factors and outcomesResultsA total of 50 patients underwent flexor tenotomy, 25 for treatment of an ulceration and 25 for treatment of a pre-ulcerative lesion. The average length of follow-up was 786.32 days (range 36-1654 days). Healing of the index ulcer or pre-ulcerative lesion was noted in 92%. Transfer lesions were noted in 28%, of which 85.7% required a subsequent flexor tenotomy to address the secondary lesion/ulceration. No patients with prophylactic flexor tenotomy developed a transfer lesion.ConclusionThis study suggests the flexor tenotomy is a safe procedure with reliable rates of ulcer healing; however, it highlights a high risk of transfer lesions. Surgeons should remain vigilant for transfer lesions in the post-procedure period, and patients should be advised of the risk for transfer lesions after index flexor tenotomy.Levels of EvidenceLevel 4.</p>","PeriodicalId":73046,"journal":{"name":"Foot & ankle specialist","volume":" ","pages":"19386400261456904"},"PeriodicalIF":2.1,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148254531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radial extracorporeal shockwave therapy (rESWT) is widely used in physiotherapy for its practicality and cost-effectiveness. However, heterogeneity in study designs and protocols limits conclusions regarding its efficacy compared with other electrophysical modalities (EPMs). This systematic review and meta-analysis aimed to synthesize the immediate effects of rESWT, alone or combined with conventional physiotherapy, versus other EPMs, focusing on pain and functional outcomes.MethodsA systematic search of PubMed, CINAHL, Scopus, Web of Science, and PEDro was conducted up to April 2025 to identify randomized controlled trials (RCTs) comparing rESWT, alone or combined with non-electrophysical interventions, versus other EPMs in adults with PF. Pain intensity and functional disability were the primary outcomes. Meta-analyses were performed using random-effects models, with sensitivity analyses conducted according to outcome type and comparator. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.ResultsFourteen RCTs (n = 797) were included, of which 12 contributed to the meta-analysis. Radial extracorporeal shockwave therapy did not demonstrate superiority over other EPMs for pain reduction (standardized mean difference [SMD] = -0.03; 95% confidence interval [CI]: -0.39 to 0.33) or functional improvement (SMD = -0.11; 95% CI: -0.47 to 0.25). Low-level laser therapy showed small but statistically significant advantages over rESWT for functional outcomes. Overall risk of bias (RoB) was high across most studies.ConclusionsRadial extracorporeal shockwave therapy, alone or combined with physical therapy, does not appear superior to other EPMs for PF. The high heterogeneity and overall elevated RoB limit the certainty of these findings, highlighting the need for high-quality trials to guide clinical recommendations.Level of Evidence:Level I: Systematic Review.</p>","PeriodicalId":73046,"journal":{"name":"Foot & ankle specialist","volume":" ","pages":"19386400261449323"},"PeriodicalIF":2.1,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148213652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early lower limb muscular fatigue and pain during exertion is the most common complaint of patients with PCFD. Surface electromyography (sEMG) provides an accurate assessment of muscle activity. In this study, we aim to compare the activities of quadriceps, hamstrings, and gastrosoleus muscle groups of adult patients with PCFD with normal lower limbs and correlate the radiological parameters and functional effects of PCFD with the activities.MethodsThirty patients with bilateral PCFD and 30 controls underwent weight-bearing anteroposterior (AP), lateral, and hindfoot alignment radiographs of the foot. Radiographic parameters of PCFD were assessed. Surface electromyography was used to assess the quadriceps, hamstrings, and gastrosoleus activities, and this was compared between the 2 groups and correlated with radiological measurements of PCFD. Tegner activity questionnaire was used to assess the functional effects of collapsed arch.ResultsElectrical activities of all muscle groups were significantly higher in cases than controls. Meary's angle and hindfoot moment arm had significant correlations with hamstring activity (P = .013) and gastrosoleus activity (P = .027), respectively. Tegner scores of cases were significantly lower than those of controls (P = .041).ConclusionsThe PCFD causes an increase in activity of large muscles of the affected lower limb which act on joints other than those in the foot. This finding may be due to several compensatory mechanisms that counteract the deforming forces. This may be a cause for the frequent complaint, early fatigue, and hence functional impairment. However, most radiological parameters did not correlate with muscle activities and larger study size may be required for further association.Levels of Evidence:Diagnostic: Level 3.</p>","PeriodicalId":73046,"journal":{"name":"Foot & ankle specialist","volume":" ","pages":"269-275"},"PeriodicalIF":2.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 2-mm diameter burr is used to create a distal first metatarsal osteotomy prior to capital fragment translation and fixation. The metatarsal will shorten by the burr's diameter (2 mm). Plantar or dorsal capital fragment displacement may also cause load transference and possibly transfer metatarsalgia. The purpose of this study is to examine the effect of MIS HV on forefoot loading mechanics with respect to metatarsal shortening and sagittal plane displacement.MethodsFour lower-limb cadaveric specimens were studied. A pedobarography pressure-sensing mat was used to record forefoot plantar pressure in a controlled weight-bearing stance position. Control and postosteotomy measurements were obtained with the capital fragment fixated in 3 possible positions: 0 mm, 5 mm dorsal, and 5 mm plantar displacement. Pedobarography data yielded pressure data within measurable graphical depictions. Raw mean contact pressure measurements were taken under the first and fourth metatarsal heads to establish medial and lateral forefoot loading pressure ratios. An a priori power analysis was performed based on previous peer-reviewed pedobarographic data, and our study was adequately powered.ResultsAround 40 measurements were recorded, and ratios of medial-to-lateral forefoot loading were constructed. Medial forefoot pressure control versus 0 mm displacement, and control versus dorsal displacement were not found to be statistically significant (<i>p</i> = 0.525, <i>p</i> = 0.55, respectively). Medial pressure significantly increased when comparing control versus plantar displacement (<i>P</i> = .006). Lateral pressure significantly increased with dorsal displacement of the osteotomy (<i>P</i> = .013).ConclusionOur study found that MIS HV correction did not cause an increase in lateral forefoot pressure loading when sagittal plane displacements were controlled.

After fracture fixation, residual syndesmotic instability was managed using syndesmotic screw in group A and dynamic fixation with a double Ethibond suture in group B. Functional results were assessed using the American Orthopaedic Foot and Ankle Society score (AOFAS) score. Radiological evaluation was done by a postoperative computed tomography (CT) scan of both ankles and plain X-rays of the ankle after surgery and at 18 months.ResultsGroup A included 20 patients meanwhile 35 patients were in group B. The reduction was satisfactory in the 2 groups according to the postoperative CT scan measurements. The mean healing time in group A was 49.65 days and 51.49 days in group B (P = .45).
