Treatment of Chronic Extensor Carpi Ulnaris Stenosing Tenosynovitis Using Ultrasound-Guided Retinaculum Release: A Case Report.

CASE: A 65-year-old man with chronic extensor carpi ulnaris (ECU) stenosing tenosynovitis who had failed treatments for 3 years was successfully treated with an ultrasound-guided retinaculum release of the sixth dorsal compartment. CONCLUSION: There are limited options in the literature for treating chronic, recalcitrant ECU tenosynovitis. We describe a novel technique in which the retinaculum overlying the ECU tendon was successfully incised under ultrasound guidance to release the sixth dorsal compartment stenosis. There was no recurrence of symptoms in the following 2 years of follow-up.

Tibialis posterior tendon entrapment in posterior malleolar and pilon injuries of the ankle: a retrospective analysis.

BACKGROUND: The Tibialis Posterior tendon (TPT) is the only tendon to encounter the distal tibia and is therefore at greatest risk of injury in fractures of the distal tibia. Although TPT injury has been reported rarely with injuries around the ankle, they often have been missed and present late. AIM: Our aim was to analyse the rate to TPT entrapment in fractures involving the posterior tibia, i.e. Pilon (PLM) and posterior malleolar fractures (PMF). METHODS: A retrospective analysis of PMF and Pilon fractures over an 8-year period was undertaken. Patients who had undergone surgical fixation of their PMF or PLM were identified from 2014 to 2022, using our prospectively collected database. Any fracture which had undergone a preoperative CT was included. Analysis of their pre-operative CT imaging was utilised to identify TPT entrapment, where if < 50% of the tendon cross section was present in the fracture site, this was denoted as a minor entrapment and if ≥ 50% of the tendon was present in the fracture site was denoted as major. RESULTS: A total of 363 patients were identified for further analysis, 220 who had a PMF and 143 with PLM injury. The incidence of TPT entrapment was 22% (n = 79) with 64 minor and 15 major entrapments. If the fracture line entered the TPT sheath, there was a 45% rate (72/172) of entrapment as compared to 3.7% (7/190) in fractures not entering the sheath (p < .001). There was no significant difference in TPT entrapment in PMF as compared to PML (p = 0.353). CONCLUSION: In our assessment, we found significant prevalence of 22% of TPT entrapment in fractures involving the posterior tibia. PMF and PLF had no statistically significant difference in the rate of TPT entrapment. Additionally, we found that there was a significant risk of TPT entrapment when the CT images display the fracture line entering the tendon sheath. We recommend that surgeons consider taking care assessing pre-operative imaging to seek to identify the TPT and to assess intraoperatively where entrapment does occur.

Irreducible Ankle Fracture Dislocation Because of Tibialis Posterior and Flexor Digitorum Longus Tendon Entrapment in the Interosseous Membrane: A Case Report.

CASE: We describe the case of a 63-year-old man with anterior ankle dislocation and fracture confirmed by x-ray. Postreduction x-ray and computed tomography (CT) revealed Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) type 44C3 and Lauge-Hansen pronation-external rotation-type ankle fractures. CONCLUSION: This was a rare case of ankle fracture dislocation because of entrapment of the tibialis posterior and flexor digitorum longus tendons in the interosseous membrane. Tendon entrapment should be suspected in cases of high-energy injuries, Weber type C fractures, Lauge-Hansen pronation-external rotation fractures, syndesmosis widening, and irreducible fractures using manual closed reduction. Fractures and soft tissues should be evaluated by changing the CT settings.

Physeal Distal Radial Fracture with Entrapment of the Tendons of Extensor Pollicis Longus and Extensor Digitorum Communis to Index Finger.

We report the entrapment of the extensor tendons following a growth plate fracture of the distal radius in a teenager. It is difficult to detect tendon entrapment at the fracture site immediately after the injury and diagnosis is typically made after fracture union when patients present with an inability to extend the thumb/reduced digital movement. A careful examination of our patient demonstrated some loss of digital motion and the plain radiographs, and computed tomographic scan showed incomplete reduction suggesting tendon entrapment. Early detection of the entrapped tendons allowed prompt release averting the need for tendon reconstruction. This report highlights the need for clinicians to maintain a high index of suspicion for tendon entrapment in patients with distal radius fractures that present with limited digital motion associated with incomplete reduction. An early diagnosis followed by the timely release can result in excellent outcomes. Level of Evidence: Level V (Therapeutic).

Stenosing tenosynovitis with rice bodies formation diagnosed by ultrasound: A case report.

RATIONALE: Rice bodies are usually found in several nonspecific chronic inflammatory diseases that are symptomatically dominated by primary disease and local compression symptoms. Rice bodies are usually detected by magnetic resonance imaging; however, some remote areas and areas with poor economic conditions do not have access to magnetic resonance imaging examination, which leads to delayed diagnosis of the disease. PATIENT CONCERNS: We report the case of a 62-year-old man with pain in the metacarpophalangeal joint of his right middle finger and limited flexion activity of his middle finger. DIAGNOSES: The mass was 1 cm, well-circumscribed, soft, and painless. Ultrasound showed stenosing tenosynovitis with rice body formation. INTERVENTIONS: The patient underwent tenosynovectomy with synovectomy of the right middle finger tendon sheath under plexus block anesthesia. OUTCOMES: No postoperative complications were noted. A 6-month follow-up showed no recurrence. The activity of the patient's middle finger improved significantly. LESSONS: Stenosing tenosynovitis with rice body formation is a very rare condition, and we use ultrasound for diagnosis. Ultrasound is convenient, rapid, inexpensive, and can obtain blood flow information, facilitate disease follow-up, and even allow ultrasound localization in advance for guided needle biopsy.

Radial Wrist Extensor Tendon Entrapment in Volarly Displaced Distal Radius Fracture: A Report of 2 Cases.

CASE: We experienced 2 cases of these entrapments. In the first case, the entrapment was identified immediately and treated successfully. In the second case, the entrapment was diagnosed after union when the disturbance of wrist flexion became apparent. CONCLUSION: When there is a longitudinal fracture line at the vicinity of the second compartment, the entrapment of extensors should be suspected even when acceptable overall alignment is accomplished.

Irreducible Lisfranc injury by tibialis anterior tendon entrapment: A case report.

RATIONALE: Lisfranc injuries are a dislocation of the metatarsal bones from the tarsal bone. Although closed reduction is possible in most cases of Lisfranc injury when attempted in the early stage, there are some rare cases for which open reduction is required. Herein we report a case of irreducible Lisfranc injury in a 34-year-old man who presented to our institution with painful swelling. PATIENT CONCERNS: We report a 34-year-old man presented to our institution with painful swelling after a fall from 1.0 m height. DIAGNOSES: We diagnosed it as irreducible Lisfranc injury by tibialis anterior tendon entrapment through plain radiologic study and surgical findings. INTERVENTIONS: Plain X-ray, C-arm fluoroscopy and open surgery were performed. OUTCOMES: We did a closed reduction under a C-arm fluoroscopic guide, but it was not successful. Thus, we had to do an open reduction of a Lisfranc dislocation. Upon exposure, we observed the entrapment of the tibialis anterior tendon between the medial and intermediate cuneiform bones. LESSONS: Our report is valuable in that it can contribute to the diagnosis and suggest a clue to the treatment of such a rare pathology. The knowledge in the rare case of entrapment of the tibialis tendon and the understanding of management will be useful when a irreducible Lisfranc dislocation is unsuccessful after an attempt at closed reduction.

Entrapment of the extensor pollicis longus tendon in a pediatric Smith fracture: A case report.

RATIONALE: Most pediatric distal radius fractures are effectively treated nonoperatively; however, operative intervention is indicated in patients with open and highly unstable fractures, in those with concomitant neurovascular injuries and in patients whom soft tissue interposition between fracture fragments precludes anatomical reduction. Notably, soft tissue interposition between fracture fragments is diagnostically challenging. Surgeons must be mindful of this rare complication for early detection and prompt treatment. PATIENT CONCERNS: A 14-year-old boy presented to the emergency department with left wrist pain after falling from a bicycle. Plain radiography and computed tomography revealed a displaced Smith fracture, which was irreducible by closed reduction, necessitating open reduction and volar plate fixation. The patient reported inability to extend his thumb at his 6-week postoperative follow-up visit. DIAGNOSIS: Ultrasonography showed extensor pollicis longus (EPL) tendon entrapment near the fracture site. INTERVENTIONS: A second operation was performed 10 weeks after the first surgery, and intraoperative exploration revealed EPL tendon entrapment. The EPL tendon was torn to shreds; therefore, extensor indicis proprius tendon transfer was performed for EPL tendon reconstruction. OUTCOMES: The patient's thumb motion was completely restored after the second operation. LESSENS: EPL tendon entrapment in a pediatric Smith fracture is rare. Signs of EPL tendon entrapment include inability to perform active thumb extension, dorsal wrist pain radiating along the course of the EPL tendon, which is exacerbated by thumb flexion, a tenodesis effect elicited on thumb examination, and difficulty in anatomical fracture reduction. Surgical exploration of the EPL tendon is warranted in patients presenting with any of these signs following attempted reduction of a Smith fracture.

Endoscopic treatment of bilateral hallux saltans in an ordinary woman.

In this article, we present a 47-year-old female patient applying with pain in posteromedial of ankle and trigger toe complaints. There was no predisposing factor such as dance or sports or any radiological sign such as os trigonum. Posterior ankle endoscopy technique was used for evaluation and it was observed that the FHL tendon was triggered. Fibrous thickening around the tendon was released with endoscopic instruments. After release, it was observed that the FHL tendon was not triggered with toe movements. Hallux saltans can be treated by posterior endoscopic methods with an attention to the tibial nerve such as other joint and soft tissue pathologies. To the best of our knowledge, this is the first case report of endoscopic treatment of bilateral HS in an ordinary female patient.

What Patient-related Factors are Associated with an Increased Risk of Surgery in Patients with Stenosing Tenosynovitis? A Prospective Study.

BACKGROUND: Numerous patient-related risk factors have been identified as contributors to patient progression to operative treatment of stenosing tenosynovitis (STS). Identifying patients most at risk of undergoing surgery after receiving a corticosteroid injection would enable health care providers to identify patients most likely to benefit from nonsurgical treatment. QUESTIONS/PURPOSES: (1) What proportion of prospectively enrolled patients with a new diagnosis of STS did not require further intervention after a first, second, or third injection when offered up to three corticosteroid injections? (2) Which identifiable risk factors present at the initial evaluation in patients with STS are associated with the patient opting for surgical release after a trial of one, two, or three corticosteroid injections? METHODS: One hundred ninety-six patients with a presumed diagnosis of STS were evaluated between March 2014 and June 2015, and 160 patients with 186 affected fingers were prospectively enrolled after a new diagnosis of STS was made during the study period. STS was diagnosed by assessing for tenderness at the A1 pulley, passive or active triggering, and the absence of other confounding diagnoses. Only the affected finger received a corticosteroid injection, and these patients were followed up during the study period. Patients were followed for 2 years, and 135 of the 160 patients (84%) completed the final followup. Patients with recurrent symptoms were treated with up to three corticosteroid injections before undergoing A1 pulley release, although patients could elect to undergo surgery at any time. Bivariate comparisons and a multivariate logistic regression analysis were used for independent fingers (one per participant) to identify independent variables associated with progression to surgery after injection. The time between treatments (between injection and subsequent injection or between injection and surgery) for those with recurrent symptoms was also calculated. Information collected from the last time the patient could be contacted was carried forward in the analysis for all 160 patients. RESULTS: No further treatment was sought after the first, second, and third injections by 81 of 160 (51%), 16 of 45 (37%), and three of 10 patients (30%), respectively; 100 of 160 patients (63%) did not pursue further intervention. After the first, second, and third injections, 36 of 160 patients (23%), 17 of 43 patients (40%), and seven of 10 of patients, respectively, did not respond to treatment. After controlling for 21 potentially confounding patient- and disease-related variables, we found that only two risk factors at the initial presentation were protective against eventual progression to surgery: osteoarthritis in the fingers (odds ratio [OR], 0.26 [95% CI, 0.085-0.786]; p = 0.017) and a longer duration of symptoms (OR, 0.58 [95% CI, 0.38-0.89]; p = 0.012). There was no association between progression to surgery and hand dominance, finger type (thumb or other), whether the patient had diabetes, or whether the affected finger was one of multiple affected fingers. Patients who presented again for intervention (injection or surgery) did so at a mean of 153 ± 94 days. CONCLUSIONS: Although patients should be counseled that their risk of progressing to surgery after an initial corticosteroid injection is lower than for subsequently administered injections for recurrent symptoms, nonoperative treatment should not be bypassed for patients with any of the studied risk factors. LEVEL OF EVIDENCE: Level II, therapeutic study.

Bilateral snapping biceps femoris tendon: a case report and review of the literature.

Snapping biceps femoris tendon is an uncommon cause of lateral knee pain. We report the case of a 15-year-old athlete with bilateral snapping biceps femoris tendons, painful over his right lateral leg during exercise. He underwent elective exploration of the right knee which revealed an accessory biceps femoris tendon with attachment to the anterolateral tibia. The accessory tendon was released and reinserted onto the fibular head with a Krackow suture. There were no perioperative complications, and he returned to full sporting activities within 3 months. We describe the operative technique used and summarise the existing literature. Restoring the anatomy with release of the accessory tendon and reinsertion onto the fibular head is an effective technique in the management of knee pain due to snapping biceps femoris tendon. Other approaches include simple release of the anomalous tendon without reinsertion or partial resection of the fibular head. Partial resection of the fibular head is the only technique described in the literature with complication requiring a further operation on the same site. There remains a paucity of evidence in the literature regarding long-term outcomes required to inform the best operative approach. Further anatomical, intraoperative and radiological studies are required to delineate the true pathology of this condition.

Anomalous course and stenosing tenosynovitis of the extensor pollicis longus tendon at the radial styloid process: A case report.

RATIONALE: Anomalous course and tenosynovitis of extensor pollicis longus (EPL) tendon is a rare condition that presents clinical symptoms very similar to de Quervain's disease. Herein we report a case of anomalous course and tenosynovitis of the extensor pollicis longus (EPL) tendon associated with symptoms of de Quervain's disease. PATIENT CONCERNS: A 44-year-old right-handed man visited the clinic because of radial pain associated with the left wrist, which was aggravated during the previous 10 days. The patient tested positive on the Finkelstein's test and displayed a limited range of motion of the left wrist. Motion of the thumb and wrist aggravated pain. DIAGNOSES: Magnetic resonance imaging (MRI) of the left wrist suggested mild tenosynovitis at the third extensor compartment and intersection syndrome. However, clinical symptoms failed to match the MRI findings. INTERVENTIONS: A zig-zag skin incision on the radial styloid process was made. The operative findings revealed stenosing tenosynovitis with partial tearing. Retraction of the tendon extended the thumb interphalangeal joint, suggesting that the tendon was the EPL tendon rather than EPB tendon. After operation, we reviewed the MRI of the patient, which revealed that the oblique course of the EPL tendon originated from the ulnar side of the forearm to the radial styloid at the radial and proximal site of Lister's tubercle. No EPB tendon was present. OUTCOMES: At 12 months of follow-up, the patient's radial styloid process was completely asymptomatic and resumed full daily activities. LESSONS: Anomalous course of the EPL tendon is rarely reported associated with similar symptoms of de Quervain's disease. However, the knowledge and understanding of this potential anomaly in the course of EPL tendon is very important for the treatment of de Quervain's disease to decrease patient dissatisfaction after surgery.

Hallux saltans due to stenosing tenosynovitis of flexor hallucis longus: dynamic sonography and arthroscopic findings.

Triggering of the toes is rare, with isolated cases reported in the literature involving predominantly the flexor hallucis longus (FHL) tendon, a condition known as "hallux saltans" (HS). We report the dynamic sonographic findings of a 42-year-old female with a 2-month history of ankle pain and triggering of right hallux, consistent with HS. Sonography demonstrated tenosynovitis and focal thickening of FHL at the level of hindfoot, with a fibrous band adjacent to the tendon. Dynamic ultrasound showed triggering and snapping of FHL tendon during hallux flexion and extension, respectively. We present comprehensive documentation of this rare entity, including sonographic still images and cine clips, as well as correlation with arthroscopic surgical findings.

Introduction: Stenosing tendovaginitis of hand fingers or spring finger is a relatively frequent pathology that can affect people during their working life. There are several methods to solve this condition. Objective: To evaluate the used of percutaneous vaginotomy in stenosing tendovaginitis of the long fingers for eight years. Methods: A prospective longitudinal intervention was conducted with adults over 65 years of age. 468 patients formed the sample. They were diagnosed with stenosing tendovaginitis (spring finger). Surgery was performed on 532 fingers with percutaneous vagotomy from January 1, 2008 to October 31, 2015, at the Research Center on Longevity, Aging and Health. Patients were assessed six months after treatment. The variables used were age, sex, time of suffering, affected finger, surgical time, perioperative complications, and duration of pain. Newport classification was used according to the symptoms and Strickland method to assess the results. Result: There was predominance of the female sex in their sixth decade of life. The highest incidences were in the dominant hand. Satisfactory results were 98.3 percent. The average times of the variables described were significantly short. No serious complications were shown. The most affected fingers were the fourth and the third. There was predominance of stages II and III. Conclusion: Percutaneous vaginotomy satisfactorily resolved the morbidity produced by the spring finger(AU)

Low-Energy Hawkins Type III Talar Neck Fracture-Dislocation With Neurovascular and Tendon Entrapment in a Pediatric Patient.

Several serious complications can occur after talar neck fractures. However, these fractures are extremely rare in children. We present a pediatric low-energy Hawkins type III fracture-dislocation that had excessive displacement accompanied by neurovascular and tendon entrapment. A 9-year-old male patient referred to our hospital 5 hours after jumping off a swing in a children's playground. An excessively displaced talar neck fracture-dislocation was observed at the initial evaluation. The patient underwent urgent surgery. The tibialis posterior flexor digitorum longus tendons, posterior tibial artery, and tibial nerve were entrapped at the fracture site. The talar neck fracture was reduced using open reduction. The neurovascular structures and tendons were removed from the fracture site. The fracture was fixed using two 4.5-mm cannulated screws. The patient was able to bear full weight at 10 weeks postoperatively. At 6 months, the patient was able to walk unassisted with full ankle range of motion. However, at 2 years, his American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale score had decreased to 72 points, and we observed avascular necrosis in the talar head. In conclusion, talar fractures are rare but can lead to serious complications. In the pediatric population, even low-energy trauma, such as had occurred in our patient, can result in severe displaced fracture-dislocations. After severe displaced fracture-dislocations, important soft tissue structures can become entrapped between fracture fragments, and surgeons should be aware of this situation when considering using closed reduction.

Incarceration of the Posterior Tibial Tendon in an Isolated Comminuted Medial Malleolus Fracture.

Isolated medial malleolar fractures are a less common presentation of an ankle fracture. Treatment is not universally accepted, although many have agreed that any displacement warrants anatomic reduction and fixation. We present a case of an isolated, comminuted medial malleolar fracture that was displaced secondary to entrapment of the posterior tibial tendon between the fracture fragments requiring surgical intervention. The patient was treated with prompt open reduction and internal fixation and had an excellent functional outcome at 1 year. When open reduction and internal fixation of the medial malleolus is indicated, a thorough exploration of the zone of injury is required to identify and adequately address any surrounding pathologic features beyond just the disrupted bony anatomy. To the best of our knowledge, this specific injury has never been previously reported and emphasizes the importance of understanding the local anatomy and how restoration of the distorted anatomy is vital to optimize patient function.

Case Report: Irreducible Ankle Fracture With Posterior Tibialis Tendon and Retinaculum, Deltoid Ligament, and Anteromedial Joint Capsule Entrapment.

Irreducible ankle fractures are a relatively rare phenomenon. We present a case of a pronation abduction-type ankle fracture that was irreducible in the emergency room despite sedation. The patient was taken to the operating room, where the posterior tibialis tendon and retinaculum, deltoid ligament, and anteromedial capsule were found to be trapped within the joint. After removal of the tissue, alignment was restored. The patient did well clinically and was advanced to full weightbearing at 6 weeks. This is, to the best of our knowledge, the first report of entrapment of all 4 anatomic structures, preventing closed reduction.

Rodilla en resorte interno por engrosamiento de la pata de ganso / Snapping knee caused by the thickening of the medial hamstrings

Presentamos el caso clínico de una paciente con rodilla en resorte, sintomática por subluxación de los tendones de la pata de ganso (semitendinoso y grácil) sobre el cóndilo medial de la tibia, debido al engrosamiento de los mismos. La clínica se reproducía durante la extensión activa de la rodilla por parte de la paciente. Para llevar a cabo al diagnóstico, a parte de la exploración física, la ecografía dinámica fue clave, ya que el resto de pruebas de imagen fueron normales. Debido al fallo del tratamiento conservador con fisioterapia e infiltraciones, se llevó a cabo tratamiento quirúrgico mediante desinserción y escisión de 8cm distales del semitendinoso y del grácil. La paciente lleva actualmente 6 meses intervenida y se encuentra asintomática, llevando a cabo con total normalidad sus actividades de la vida diaria (AU)

We report a case of symptomatic subluxation of the semitendinosus and gracilis over the medial condyle of the tibia caused by the thickening of its tendons. Snapping was reproduced on active extension. Clinical examination and, above all, dynamic ultrasound were the key for the diagnosis because other imaging tests were normal. Due to failure of conservative treatment with physiotherapy and infiltrations, surgery was undertaken, involving desinsertion and excision of distal 8cm segment of the semitendinosus and gracilis tendons. At the present time (6 months postoperatively), the patient is symptom-free and has returned to the previous normal life activities (AU)

Síndrome de Haglund. A propósito de 2 casos / Haglund's syndrome. Two case reports

El síndrome de Haglund es una causa de atrapamiento tendino-bursal posterior del talón, producida por una exostosis posterosuperior del calcáneo, denominada deformidad de Haglund, asociada a tendinitis aquílea y bursitis retrocalcánea. Su patogenia es desconocida. Se presentan 2 casos, diagnosticados clínicamente, confirmados radiológicamente, y tratados conservadoramente uno y con cirugía el otro. El diagnóstico se realiza por la clínica y por las imágenes radiológicas con el método de medición de las líneas de inclinación paralelas, en una radiografía lateral del tobillo. El tratamiento inicial suele ser conservador e incluye antiinflamatorios o analgésicos, fisioterapia y zapatos con talón abierto y sin tacón alto. Si el tratamiento conservador no alivia el dolor, puede ser necesaria la cirugía (AU)

Haglund's syndrome produces posterior impingement of the heel, which is caused by a posterosuperior calcaneal exostosis, known as Haglund's deformity, associated with Achilles tendinitis and retrocalcaneal bursitis. Its pathogenesis is unknown. We report two cases that were diagnosed clinically and confirmed radiographically. One patient was treated conservatively and the other underwent surgery. The diagnosis is based on clinical signs and radiological images, using the measurement of the parallel pitch lines, in a lateral radiograph of the ankle. Initial treatment is usually conservative and includes anti-inflammatory or analgesic agents, physiotherapy and low-heeled, open-heeled shoes. If conservative treatment does not relieve the pain, surgery may be necessary (AU)
