Ex Vivo Study

Aim of this study was to document the normal computed tomographic tenography findings of digital flexor tendon sheath. Six ex vivo normal equine forelimbs were used. An axial approach was used to inject 185 mg/mL of iopamidol in a total volume of 60 mL into the digital flexor tendon sheaths. Single-slice helical scans, with 5 mm thickness, spaced every 3 mm, for a pitch of 0.6, and with bone algorithm reconstruction, were performed before and after injections of contrast medium. To obtain better image quality for multiplanar reconstruction and 3D reformatting, postprocessing retroreconstruction was performed to reduce the images to submillimetre thickness. Computed tomographic tenography of digital flexor tendon sheaths could visualize the following main tendon structures for every forelimb in contrast-enhanced images as low densities surrounded by high densities: superficial digital flexor tendon, deep digital flexor tendon, manica flexoria, mesotendons, and synovial recess. Results of this study suggest that computed tomographic tenography can be used with accuracy and sensitivity to evaluate the common disorders of the equine digital flexor tendon sheath and the intrathecal structures.

Distal Aspect

A six-year-old warmblood horse was presented with a longstanding frontlimb lameness with mild digital flexor tenosynovitis and swelling of the distomedial pastern. Ultrasonography and magnetic resonance revealed a dense mass lesion in the distal aspect of the digital flexor tendon sheath, with a partial lamellar architecture, absence of internal vascularization and adjacent smooth pressure osteolysis of the middle phalanx. After surgical excision, histopathology confirmed an epithelial inclusion cyst. Epithelial inclusion cysts, also known as keratinizing or follicular cysts, are expansile benign mass-like lesions of aberrant epidermal tissue. In the horse, they are known to occur in cutaneous and several non-cutaneous tissues. In the digital flexor tendon sheath, they have rarely been described. Given their often chronic presentation in this location, they may appear as an atypical dense mass on imaging, uncommon for cystic lesions. Complete tenoscopic removal, even for larger masses, is achievable and considered curative with good prognosis for return.

Injection studies using methylene blue and latex were used in 60 digits from 40 cadavers to study how anaesthetic fluid injected into the flexor tendon sheath might spread around the proximal part of the finger. The injected solution escaped from the flexor tendon sheath around the vincular vessels which are present near the base and head of the proximal phalanx. Outside the digital canal, the dye flowed smoothly through the perivascular loose areolar tissue and spread alongside the main digital vessels and nerves and their palmar and dorsal branches.

Flexor Tendon Sheath

Two unusual cases of injury to the sesamoids of the M.P. joint of the thumb are described. An anatomical dissection of the M.P. volar plate region, including the sesamoids, was undertaken to delineate the details of the sesamoids’ relationship to the M.P. joint, flexor tendon, flexor tendon sheath and capsule of the joint. Histological studies were carried out to demonstrate a tendinous extension of the muscles that attach to the sesamoids.

Tenosynovial Giant Cell Tumour

Giant cell tumor of the tendon sheath is a common benign lesion of the hand. They are also known as tenosynovial giant cell tumours. Magnetic resonance imaging is the imaging modality of choice and the current treatment is surgical excision of the lesion. This lesion is particularly known for its high recurrence rates. Here, we present a case of a recurrent tenosynovial giant cell tumour of the flexor tendon sheath of the index finger at the distal palmar crease. Diagnosis was confirmed by MRI and the lesion was excised. Histopathology revealed a localized type of tenosynovial giant cell tumour.
