[Multiple verruca plantaris treated with modified fire-needle technique and herbal bathing-repairing therapy of TCM: a randomized controlled trial].

OBJECTIVE: To observe the clinical effect of modified fire-needle technique and herbal bathing-repairing therapy of TCM on multiple verruca plantaris. METHODS: Seventy patients with multiple verruca plantaris were randomly divided into an observation group (35 cases, 1 case was eliminated) and a control group (35 cases, 2 cases dropped out). In the control group, the herbal bathing-repairing therapy of TCM was adopted. In the observation group, besides the treatment as the control group, fire needling and cauterization were delivered on the base of skin lesion or the sites with rich blood vessels under the dermoscope. The intervention was provided once a week, one course of treatment was composed of 3 weeks, and two courses were required in each group. The score of the self-designed symptom scale, the score of dermatology life quality index (DLQI) and the area of typical skin lesion were observed before and after treatment. The clinical effect was evaluated after treatment and the recurrence was assessed 2 months after treatment completion in the two groups. RESULTS: After treatment, the scores of the self-designed symptom scale and DLQI were lower and the area of typical skin lesion was smaller compared with those before treatment in the two groups (P<0.05). The scores of the self-designed symptom score and DLQI in the observation group were reduced (P<0.05), and the area of typical lesion was smaller (P<0.05) in comparison with those in the control group. The total effective rate was 91.2% (31/34) in the observation group, higher than that in the control group (60.6%, 20/33, P<0.05). The recurrence rate was 6.5% (2/31) in the observation group, lower than that in the control group (35.0%, 7/20, P<0.05). CONCLUSION: Modified fire-needle technique combined with herbal bathing-repairing therapy ameliorates clinical symptoms and the quality of life in the patients with multiple verruca plantaris and reduces the recurrence of the disease.

Plantaris Tendon Autograft Can Restore Patellar Stability in Adolescent Medial Patellofemoral Ligament Reconstruction: A Technical Note.

Medial patellofemoral ligament reconstruction is a standard treatment option for patients with patellar instability. The main purpose of this study was to determine whether isolated anatomic medial patellofemoral ligament reconstruction using double folded, four-strand plantaris tendon autograft restores patellar stability in adolescent patients. Plantaris tendon autografts were harvested through proximal approach and used in four adolescent patients. A four-strand autograft was prepared in a double-limbed configuration and fixed on the patella and the femur with suture anchors and interference screws, respectively. The mean Kujala score improved significantly from 44 ± 24 SD (range, 19 to 69) points preoperatively to 94 ± 10 SD (range, 78 to 100) points postoperatively (P< 0.001). All patients reported excellent subjective outcomes and returned to their pre-injury level of sporting activities. The use of a four-strand plantaris tendon autograft in isolated anatomic medial patellofemoral ligament reconstruction can restore patellar stability in adolescents.

Ultrasound assessment of acute Achilles tendon rupture and measurement of the tendon gap.

Achilles tendon rupture is a common sports-related injury which can carry significant morbidity to patients. Ultrasound remains the workhorse of imaging as it can confirm and localise the extent of Achilles tendon injury. The sonographic anatomy, both normal and ruptured sonographic appearances, as well as sonographic technique must be appreciated to accurately image and report findings, critical to patient management. Particular attention should be applied to the measurement of the diastasis between acutely ruptured tendon ends as this information can assist with informing the decision of conservative vs. operative management. Further work is necessary to standardise the measurement technique including correlating the degree of plantarflexion of the foot with the sonographic tendon gap measures.

A bilateral gastrocnemius tertius coexisting with a unilateral two-headed plantaris muscle.

The current cadaveric report aims to present a coexistence of two uncommon variants of the posterior leg compartment. The variations were detected, during classical dissection in an 84-year-old donated male cadaver. On the left lower limb, the gastrocnemius muscle was identified as having a third head that was attached to the lateral head. This variant is known as gastrocnemius tertius muscle and was bilaterally identified. The left-sided plantaris muscle had two distinct heads that fused into a common tendon that was inserted into the calcaneal tuberosity. Knowledge of these variants is important, due to their close relationship with the popliteal neurovascular bundle. Clinicians should be aware, to avoid pitfalls and take them into account in their differential diagnosis.

Never undescribed four - headed plantaris muscle.

The plantaris is a small muscle of the superficial posterior compartment of the leg. It originates at the lateral supracondylar line of the femur and the knee joint capsule, from where it continues distally, forming a long and slender tendon distally attached to the calcaneal tuberosity. During standard anatomical dissection four-headed plantaris muscle was found and all of its heads connected to each other as a single muscle belly passing into tendinous structure which was distally attached as a standard plantaris muscle. The first head originated from the popliteal surface of the femur. The second one was originated from distal Kaplan fiber. In turn, the third and fourth heads were proximally attached to the lateral femoral epicondyle. Knowledge about morphological variations is necessary because of its potential clinical significance, which means not only neurovascular compressions, but also surgical procedures.

Tendinopathic Plantaris but Normal Achilles Tendon Found in About One-Fifth of Patients Not Responding to Conservative Achilles Tendon Management - Results from a Prospective WALANT Surgical Case Series on 105 Tendons.

Purpose: Midportion Achilles tendinopathy is a relatively common condition. This study aimed to investigate the presence of a normal Achilles tendon, but a tendinopathic plantaris tendon, in a large and consecutive prospective sample of patients referred to a specialised tendon clinic for midportion Achilles tendon pain not responding to non-surgical treatment. Patients and Methods: A total of 105 consecutive tendons were operated on in 81 patients (62 males) suffering from painful midportion Achilles tendon pain. Clinical examination, ultrasound (US) and colour Doppler (CD) examination, and wide awake local anaesthetic no tourniquet (WALANT) surgery were performed in all patients. Results: For 19/105 (18%) tendons from 14 patients, clinical examination suspected plantaris tendinopathy alone as there was a distinct tenderness on the medial side, but no thickening of the Achilles tendon. US examination followed by surgery confirmed the diagnosis. Conclusion: Midportion Achilles tendon pain is not always related to Achilles tendinopathy since pain related to the plantaris tendon alone was found in almost every fifth patient. Consequently, there is an obvious need for proper examination to identify the pain source and establish a correct diagnosis before treatment.

[Anatomical and biomechanical characteristics of plantaris tendon and its application in ligament reconstruction].

Objective: To improve the clinical utility of the plantaris tendon mainly by summarizing its anatomical characteristics, biomechanical properties, harvesting methods, and its applications in ligament reconstruction. Methods: The relevant literature from domestic and international databases regarding the anatomical and biomechanical characteristics of the plantaris tendon and its applications in ligament reconstruction was comprehensively reviewed and systematically summarized. Results: The plantaris tendons have an absence. The majority of plantaris tendon forms a fan-shape on the anterior and medial sides of the Achilles tendon and terminates at the calcaneal tuberosity. There are significant differences in biomechanical parameters between plantaris tendon with different numbers of strands, and multi strand plantaris tendon have significant advantages over single strand tendon. The plantaris tendon can be harvested through proximal and distal approaches, and it is necessary to ensure that there are no obvious anatomical variations or adhesions in the surrounding area before harvesting. The plantaris tendon is commonly utilized in ligament reconstruction around the ankle joint or suture reinforcement for Achilles tendon rupture, with satisfactory effectiveness. There is limited research on the use of plantar tendon in the reconstruction of upper limb and knee joint ligaments. Conclusion: The plantaris tendon is relatively superficial, easy to be harvested, and has less impact on local function. The plantaris tendon is commonly utilized in ligaments reconstruction around the ankle joint or suture reinforcement for Achilles tendon rupture. The study on the plantaris tendon for upper limbs and knee joints ligament reconstruction is rarely and require further research.

Quantitative study of the popliteal fossa in the human fetus.

The popliteal fossa presents an extensive diamond-shaped topographical element on the posterior aspect of the knee. With the use of classical anatomical dissection, digital image analysis of NIS Elements AR 3.0 and statistics we morphometrically analyzed the size of the popliteal fossa in human fetuses aged 17-29 weeks of gestation. Morphometric parameters of the popliteal fossa increased logarithmically with fetal age: y = -44.421 + 24.301 × ln (Age) for length of superomedial boundary, y = -41.379 + 22.777 × ln (Age) for length of superolateral boundary, y = -39.019 + 20.981 × ln (Age) for inferomedial boundary, y = -37.547 + 20.319 × ln (Age), for length of inferolateral boundary, y = -28.915 + 15.822 × ln (Age) for transverse diameter, y = -69.790 + 38.73 × ln (Age) for vertical diameter and y = -485.631 + 240.844 × ln (Age) for projection surface area. Out of the four angles of the popliteal fossa the medial one was greatest, the inferior one the smallest, while the lateral one was somewhat smaller than the medial one and approximately three times greater than the superior one, with no difference with fetal age. In terms of morphometric parameters the popliteal fossa in the human fetus displays neither male-female nor right-left differences. In the popliteal fossa, growth patterns of its four boundaries, vertical and transverse diameters, and projection surface area all follow natural logarithmic functions. All the morphometric data is considered age-specific reference intervals, which may be conducive in the diagnostics of congenital abnormalities in the human fetus.

[Treatment of therapy-resistant verruca plantaris with laser-assisted photodynamic therapy (PDT) with methyl aminolevulinate (MAL)]. / Therapie von behandlungsresistenten Mosaikwarzen mittels laserassistierter photodynamischer Therapie (PDT) mit Methylaminolävulinat (MAL).

Mosaic warts are a type of verruca vulgaris that occur almost exclusively on the soles of the feet. They are particularly known for their treatment resistance and high recurrence rate. Laser-assisted drug delivery (LADD) photodynamic therapy (PDT) with methyl aminolevulinate (MAL) offers a low pain treatment option with hardly any side effects in therapy-resistant cases of verruca plantaris. Pretreatment with an ablative fractional laser is especially important to obtain penetration of MAL through the human papillomavirus (HPV)-infected skin layer.

A three-headed plantaris muscle fused with Kaplan fibers: potential clinical significance.

The plantaris is a short, small muscle that usually originates at the popliteal surface of the femur and has a long, thin tendon that typically inserts into the calcaneal tuberosity. Its role and degree of development have been objects of debate for years. Some authors consider it a vestigial muscle while others believe it is a process of its development. The clinical significance of plantaris muscle is usually related to its morphological variation, which is common and well described in the literature. These variations are often a risk factor for many ailments and disorders. We would like to present another, very rare case of three-headed plantaris muscle (fused with distal Kaplan fibers), and consider what clinical implications it may have.

Evaluating the Suitability of the Plantaris Tendon for Sports Trauma Reconstruction and a Predictive Model of Tendon Length Based on Height and Leg Length.

This study evaluates the suitability of the plantaris tendon (PT) as a tendon graft donor for sports trauma reconstruction and proposes a predictive model for estimating PT length by using an individual's height and leg length. Anatomical dissection of 50 cadavers (32 males and 18 females) yielded precise measurements of PT length and width while also recording height and leg length. Among the lower limbs, 89% were suitable for at least one recommended graft suitability criterion. In addition, PT length exhibited robust positive correlations with height and leg length. Predictive equations were established for estimating the PT length based on leg length and height with consistency across sexes and sides: PT length = 0.605 + 0.396 × leg length (r = 0.721) and PT length = 1.480 + 0.193 × height (r = 0.626). This study underscores the grafting potential of the PT, providing a predictive tool that can aid surgeons in addressing tendon graft challenges within sports trauma scenarios.

Morphological variability of the leg muscles: potential traps on ultrasound that await clinicians.

BACKGROUND: Although muscles and their tendons are not considered the most morphologically variable structures, they still manifest a substantial diversity of variants. The aim of this study is to increase awareness of some of the many possible variants found during ultrasound imaging of one lower limb compartment, the leg, that could potentially mislead clinicians and lead to misdiagnosis. MATERIALS AND METHODS: PubMed was used for a comprehensive literature search for morphological variations. Relevant papers were included, and citation tracking was used to identify further publications. RESULTS: Several morphological variants of muscles of the leg have been described over many years, but this study shows that the occurrence of further variations in ultrasound imaging requires further investigations. CONCLUSIONS: The incidence of additional structures including muscles and tendons during ultrasound examination can cause confusion and lead to misinterpretation of images, misdiagnosis, and the introduction of unnecessary and inappropriate treatments.

Spectrophotometric intracutaneous analysis findings and characteristics in plantar verrues.

BACKGROUND: Spectrophotometric intracutaneous analysis (SIAscopy) is a non-invasive computerized method that provides insights beyond dermoscopic examination. This study aimed to show the various findings of the plantar verrucae with the SIAscopy evaluation, which displays the chromophores of the skin, melanin, hemoglobin, and collagen. METHODS: Plantar verrucae lesions scanned using SIAscopy, and their color, total melanin, dermal melanin, collagen, and blood views were recorded on a computer. These SIAgraphs were examined individually and compared to dermoscopic literature findings. RESULTS: The results of color view were in conformity with dermoscopic findings reported in the literature. Among the findings detected for the first time by a SIAscopic examination, a white halo around the vessel in view of total melanin, effacement in the keratinized areas, and whitening in the vascular areas were noted. There was a mottled collagen condensation, which was believed to be induced by dermal papillomatosis in the lesions in the view of collagen, and consequently, as a result of remittent light reflections due to the collagen structure in this area. There was a clarification in the vascular structures that were noticed in the color view in the blood view. It was noted that vascular structures that have not yet been thrombosed under the thickened epidermis could not be detected in color view. CONCLUSION: Our study reveals that SIAscopy, a rapid, non-invasive, and easy-to-use examination method similar to dermoscopy, can also diagnose other skin diseases, particularly pathogenetic processes that induce epidermal and papillary dermis changes, apart from pigmented lesions.

Accessory plantaris muscle can result in symptomatic hardware impingement following ACL reconstruction.

Anatomic variants of lower extremity musculature, such as the gastrocnemius, popliteus, and the plantaris have been well described in the literature. The impact of these anatomical variations on clinical outcomes depends on their proximity to and effects on adjacent anatomical structures, particularly in the context of planned surgical procedures in the region. While the presence of the accessory plantaris is rare, no previous cases have described it negatively affecting surgical outcomes to our knowledge. We present a case of a 42-year-old patient who underwent an anterior cruciate ligament (ACL) reconstruction using a femoral Endobutton for graft fixation positioned just beneath an accessory plantaris, leading to impingement and persistent knee pain. This case highlights the importance of understanding anatomical variations when planning and performing surgical procedures and suggests the need for further research in this area.

Radiologic and clinical outcomes of an arthroscopic bridging graft for irreparable rotator cuff tears with a modified MasonAllen stitch using a plantaris tendon autograft: a case series with minimum 2-year outcomes.

BACKGROUND: Surgical management of a massive rotator cuff tear (RCT) is always challenging. This study describes the clinical and radiological outcomes of patients who underwent bridging grafts using a plantaris tendon for an irreparable RCT. METHODS: Thirteen patients with a massive RCT were treated with arthroscopic interposition of a folded plantaris tendon autograft between June 2017 and January 2020. For clinical evaluation, a visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, Constant-Murley score, and range of motion values were collected. For radiographic evaluation, standardized magnetic resonance imaging and ultrasonography were performed to check the integrity of the interposed tendon. RESULTS: A statistically significant improvement at the final follow-up was evident in scores for the VAS (-3.0, P=0.003), ASES (24.9, P=0.002), D ASH (-20.6, P=0.001), and Constant-Murley values (14.2, P=0.010). In addition, significant improvement was shown in postoperative flexion (17.3°, P=0.026) and external rotation (27.7°, P<0.001). In postoperative radiologic evaluations, the interposed tendons were intact at the last examination in 12 of the 13 patients. No complications related to donor sites were reported. CONCLUSIONS: An arthroscopic bridging graft for irreparable RCTs using a modified Mason-Allen stitch and a plantaris autograft resulted in improved short-term radiological and clinical outcomes. Graft integrity was maintained for up to 2 years in most patients. Level of evidence: IV.

Warts in pediatric oncology patients: A single-institution retrospective study.

BACKGROUND: Pediatric oncology patients undergoing cancer treatment can often have numerous and recalcitrant cutaneous warts due to their underlying immunosuppression. There are little published data on the optimal management of warts in pediatric oncology patients undergoing active cancer treatment compared to patients having completed treatment. Our objective was to analyze the clinical course of warts treated within this patient population at Boston Children's Hospital over a 10-year period. METHODS: This was a single-institution retrospective study of 72 pediatric oncology patients from 1 September 2011 to 1 September 2021 who were treated for warts at Boston Children's Hospital. All patients had a diagnosis of cutaneous warts with at least one follow-up visit and were receiving active treatment for cancer either during or after concurrent treatment of their warts. We examined the modality and effectiveness of wart treatments while both on and offactive treatment of their cancer. RESULTS: The median age was 12 years (range 4-18). Fifty-four percent of patients were documented to have plantar warts. Sixty percent of patients with a documented number of warts had more than five warts at presentation. For cases in which outcomes were specified, treatment resulted in complete resolution of warts in only 24.0% of patients undergoing active cancer treatment compared to 63.3% of patients not on active treatment. Warts persisted or worsened in 56.0% of patients undergoing active cancer treatment compared to only 13.4% of patients not on active treatment. CONCLUSION: These data may help guide clinicians in evaluating and treating warts in pediatric oncology patients.

Spiny Keratoderma in Association with Melanoma.

Spiny keratoderma (SK) was first described by Brown in 1871 and is characterized by numerous 1-2 mm spines of keratin on the palms and soles, usually sparing the dorsal surfaces, or disseminated over the trunk. Histologically, the "spine" represents a column of hyperkeratosis. Several different forms are known, including familial, sporadic, post-inflammatory and paraneoplastic. Although an association of SK with melanoma has been reported, the significance of such co-occurrence remains unclear due to the limited number of cases. To increase the body of knowledge and shed further light on this rare condition, we present a case of SK in a patient with a recent history of melanoma in situ.

Combined Midportion Achilles and Plantaris Tendinopathy: A 1-Year Follow-Up Study after Ultrasound and Color-Doppler-Guided WALANT Surgery in a Private Setting in Southern Sweden.

Background and Objectives: Chronic painful midportion Achilles combined with plantaris tendinopathy can be a troublesome condition to treat. The objective was to prospectively follow patients subjected to ultrasound (US)- and color doppler (CD)-guided wide awake, local anesthetic, no-tourniquet (WALANT) surgery in a private setting. Material and Methods: Twenty-six Swedish patients (17 men and 9 women, mean age 50 years (range 29-62)) and eight international male patients (mean age of 38 years (range 25-71)) with combined midportion Achilles and plantaris tendinopathy in 45 tendons altogether were included. All patients had had >6 months of pain and had tried non-surgical treatment with eccentric training, without effect. US + CD-guided surgical scraping of the ventral Achilles tendon and plantaris removal under local anesthesia was performed on all patients. A 4-6-week rehabilitation protocol with an immediate full-weight-bearing tendon loading regime was used. The VISA-A score and a study-specific questionnaire evaluating physical activity level and subjective satisfaction with the treatment were used for evaluation. Results: At the 1-year follow-up, 32/34 patients (43 tendons) were satisfied with the treatment result and had returned to their pre-injury Achilles tendon loading activity. There were two dropouts (two tendons). For the Swedish patients, the mean VISA-A score increased from 34 (0-64) before surgery to 93 (61-100) after surgery (p < 0.001). There were two complications, one wound rupture and one superficial skin infection. Conclusions: For patients suffering from painful midportion Achilles tendinopathy and plantaris tendinopathy, US + CD-guided surgical Achilles tendon scraping and plantaris tendon removal showed a high satisfaction rate and good functional results 1 year after surgery.

Reconstruction of the lateral collateral ligament using the plantaris tendon after wide excision of soft tissue sarcoma of the knee: A case report.

An 83-year-old woman presented with a 1-year history of a growing mass on the lateral surface of the right knee. Magnetic resonance imaging revealed a large soft tissue tumor in the subcutis of the right knee. The mass in the right knee rapidly increased, due to hemorrhage from the tumor. A needle biopsy revealed that the diagnosis was synovial sarcoma. The patient underwent wide excision and lateral collateral ligament reconstruction using the plantaris tendon. The patient had a Musculoskeletal Tumor Society Score of 86% at the lateset follow-up. In conclusion, reconstruction of the lateral collateral ligament using the plantaris tendon may be useful for preserving the function of the knee joint after resection of the soft tissue due to sarcoma of the knee.
