Flexor pollicis longus (FPL) tendon hypoplasia: A case report and literature review.

ABSTRACT: An 18-year-old female presented with long-standing inability to flex her left thumb. MRI of the left thumb revealed flexor pollicus longus (FPL) tendon hypoplasia, and subsequent ultrasound of the bilateral thumbs confirmed a left-sided hypoplastic FPL tendon. Structural integrity of the left FPL tendon was confirmed during surgical examination under anesthesia. Multiple congenital anomalies of the FPL have been described, but FPL tendon hypoplasia and its appearance on imaging are rarely reported. This case demonstrates the diagnosis of FPL tendon hypoplasia on MRI, ultrasound, and surgical examination under anesthesia; and demonstrates the importance of including this entity in the differential diagnosis for impaired thumb flexion.

Absent flexor pollicis longus: case report with review of literature.

Project description:An asymptomatic absence of flexor pollicis longus without association with any other anomaly or hypoplasia of the thenar muscles in a 28-year-old patient is reported due to its rarity. The inability to flex the interphalangeal joint of the thumb and the absent flexor crease of the thumb led us to identify the absent tendon, and the tendon could not be palpated in the flexor crease of the thumb. Routine X-rays, ultrasound scans, and a computed tomography with soft tissue enhancement was used to confirm and document the condition. The patient was not referred for a magnetic resonance imaging, facilities for which are not available in the center where the author is working, as he was not keen in surgical interference.

Congenital absence of flexor pollicis longus tendon without associated anomalies of thumb hypoplasia: a case report and review of the literature.

Project description:In this paper, we report a case of a 14-year-old girl with congenital aplasia of the flexor pollicis longus tendon who had no other associated anomalies of thumb hypoplasia and no trauma history. Flexor pollicis longus tendon anomalies are rare; several types of this congenital anomaly have been reported in the literature. The diagnosis should be considered if a patient is unable to flex the interphalangeal joint of the thumb. A hypoplastic thumb or an absent interphalangeal joint crease may be a diagnostic feature in such cases. Besides physical examination, we also used direct radiography and magnetic resonance imaging to diagnose this rare congenital anomaly in our patient.

Flexor Pollicis Longus Tendoscopy.

Project description:The deep palmar spaces of the hand include the midpalmar space, the hypothenar space, the thenar space, space of Parona, and the interdigital web spaces. There are various communications between different spaces. These communications are of clinical importance in explaining the spread of inflammatory, infectious, and even neoplasic processes that involve this region. Surgical incision and drainage of all potentially communicating spaces and compartments is mandatory in deep hand infections. The purpose of this technical note is to describe the minimally invasive approach of endoscopic drainage and debridement of the flexor pollicis longus tendon sheath, radial bursa, and thenar space.

Flexor pollicis longus zone 2 tendon repair under WALANT with ultrasound assistance.

Project description:A feature of the flexor pollicis longus tendon injury is the frequency of palmar retraction so that a wrist approach is needed for retrieval of the proximal stump. We are reporting on our first outpatient zone T2 flexor pollicis longus tendon repair under WALANT with ultrasound guidance. In the event of zone T2 flexor pollicis rupture, ultrasound location of tendon extremities is used to plan surgical WALANT strategy and to guide the injection of lidocaine with epinephrine whilst limiting the injected volume to what is strictly necessary.

Distal intersection syndrome progressing to extensor pollicis longus tendon rupture: a case report with sonographic findings.

Project description:The purpose of this case report is to describe the value of musculoskeletal ultrasound (US) in diagnosing both distal intersection syndrome (DIS) and rupture of the extensor pollicis longus (EPL) tendon in the same patient. A 38-year-old female presented for evaluation of a painful bump of unknown etiology on the dorsolateral aspect of her non-dominant wrist. US demonstrated tenosynovitis distal to Lister's tubercle of the EPL and extensor carpi radialis tendon sheaths, consistent with DIS. Immobilization therapy was employed, during which time the patient suffered rupture of the EPL tendon. Follow-up US examination confirmed this additional diagnosis. Characteristic US findings of DIS and EPL tendon rupture were observed. Surgical intervention was required and the patient recovered without complication. Although EPL rupture is relatively common in the literature, DIS is rare. This is the first known case of imaging-proven DIS progressing to EPL tendon rupture. This case underscores the value of US as a widely available, cost effective, and dynamic imaging modality for evaluation of wrist complaints.

Zone II Flexor Pollicis Longus Repair: Thumb Flexion and Complications.

Project description:Background: The aim of flexor pollicis longus (FPL) repair is to create a construct that is strong enough to withstand forces encountered during rehabilitation and to achieve an optimal active range of motion. The aim of this study was to: (1) assess factors influencing active thumb interphalangeal (IP) joint flexion; and (2) assess the factors associated with reoperation. Methods: Retrospectively, 104 patients with primary repair of a Zone II FPL laceration from 2000 to 2016 were identified. A medical chart review was performed to collect patient-, injury-, and surgery characteristics as well as the degree of postoperative active IP-flexion and occurrence of reoperation. Bivariate analyses were performed to identify factors influencing active IP-flexion and factors associated with reoperation. Results: The reoperation rate was 17% (n = 18) at a median of 3.4 months (range: 2.3-4.4). Indications for reoperation mainly included adhesion formation (n = 10, 56%) and re-rupture (n = 5, 28%). The median range of active IP-flexion was 30° (interquartile range [IQR]: 20-45) at a median of 12.4 weeks (IQR: 8.1-16.7). Solitary injury to the thumb (β = 17.9, P = .022) and the use of epitendinous suture (β = 10.0, P = .031) were associated with increased active IP-joint flexion. No factors were statistically associated with reoperation. Conclusions: About 1 in 5 patients undergo reoperation following primary repair of a Zone II FPL laceration, mostly within 6 months of initial surgery. The use of epitendinous suture is associated with greater active IP-flexion. Patients with multiple digits injured accompanying a Zone II FPL laceration have inferior IP-joint motion.

Retro-Malleolar Z-Plasty of Flexor Hallucis Longus Tendon in Post-Traumatic Checkrein Deformity: A Case Series and Literature Review.

Project description:Checkrein deformity (CD) is a dynamic deformity of the hallux characterized by flexion contracture of the interphalangeal (IF) joint and extension contracture of the metatarsophalangeal (MTP) joint, worsened by ankle dorsiflexion. It is due to post-traumatic or ischemic retraction of the long hallux flexor tendon (FHL) following soft tissue trauma, leg fractures, ankle fractures and, more rarely, calcaneal or talar fractures. Diagnosis is essentially clinical, associated with imaging, to rule out unrecognized causes and evaluate fracture healing process. Few cases are reported in literature without univocal treatment. Background and Objectives: To analyze clinical and functional outcomes in patients with CD treated with release and retro-malleolar Z-plasty lengthening of FHL tendon. Materials and Methods: Patients diagnosed with CD treated with retro-malleolar (at tarsal tunnel) Z-plasty lengthening of the FHL tendon between January 2016 and August 2020 were included. Clinical and functional outcomes were collected on admission and post-surgery and analysed retrospectively. Patients with a minimum follow-up of 18 months were included. Results: A total of 14 patients, with mean age of 37.4 years old, with CD diagnosis were included in the study. All patients were suffering from post-traumatic CD and the mean time from trauma to onset of deformity was of 7 months (range 1-12). At a mean follow-up of 31.8 months (range 18-48) we found a significant improvement (p < 0.05) in terms of pain relief (VAS), function (AOFAS score) and ROM of the IP and MTP hallux joints. No recurrence, loss of strength, nerve injury or tarsal tunnel syndrome were observed. No patient required revision surgery. Conclusions: In this case series the retro-malleolar FHL tendon Z-plasty proved to be a suitable option for CD correction, allowing a good clinical and functional recovery.

Severe pure open dislocation of the ankle and flexor digitorum longus tendon tear a case report.

Project description:Proximal avulsion rupture of the flexor digitorum longus (FDL) tendon associated with an ankle dislocation is extremely rare. We report a case of a 29 years old patient presenting a severe open ankle dislocation with flexor digitorum longus tendon tear after a motorcycle accident. We performed wound debridement, ankle reduction, tendon repair and stabilization with external fixation. At our last follow-up 17 months after the operation, the patient had good functional outcome and returned to work. This report is noticeable as it is, to the best of our knowledge, the third study reporting a case with simultaneous open ankle dislocation and proximal avulsion rupture of the FDL tendon.

Extensor pollicis longus tendon penetration by a screw post-distal radius fracture plating in a young woman: A case report.

Project description:IntroductionDue to its ability to provide stable fixation and permit early mobilization, volar plating has become the recommended technique for the surgical stabilization of distal radius fractures. The extensor pollicis longus (EPL) tendon may be injured or ruptured as a result of undetected screw penetration or drill plunging. During surgery, it is critical to detect any potential screw penetration so that it can be corrected.Case presentationA 32-year-old woman presented six weeks post-distal radius plating with an inability to extend her left thumb. Clinical examination revealed loss of extension at the interphalangeal joint, stiff wrist, tender point over the dorsal aspect of the wrist, and an intact sensory nerve function.DiscussionDynamic ultrasound and magnetic resonance imaging (MRI) both revealed no evidence of tendon rupture or EPL tendon movement. X-rays revealed the distal epiphyseal screws penetrating the far cortex. Intraoperatively, the EPL tendon was found to be impinged by a screw. The tendon was released, tenolysis was performed, and the distal screws were shortened.ConclusionIn order to assess screw penetration into the far cortex, volar plating for distal radius fractures should be performed using intraoperative imaging views such as lateral, 45-degree supination, 45-degree pronation, dorsal tangential, and skyline views. Timely interventions after distal radius fracture fixation preserve tendon function, and early detection of tendon compromise is essential to preventing additional damage.

Endoscopic Tenolysis of Flexor Hallucis Longus Tendon: Surgical Technique.

Project description:Flexor hallucis longus tendon release for surgical treatment of functional hallux limitus-associated conditions is described. This release is obtained by arthroscopic correction of the tendon's blockage, which is located at the retrotalar pulley. The procedure restores the ability for dorsiflexion of the first toe in ankle dorsiflexion (positive stretch test result). Such movement was not possible before, causing a modified gait pattern and affecting the biomechanics of the foot and leg. This explains why the procedure creates favorable changes concerning foot dynamics by restoration not only of the normal tendon glide but also of the normal mobility of the subtalar joint.
