Dirofilariasis is a zoonosis affecting dogs and cats. It can be transmitted to human by mosquito bites. Because of the local inflammation caused by the parasite, a lump may develop. The authors present a case of a 13-year-old boy, who was diagnosed with dirofilariasis in association with a cyst located on the middle finger of the right hand. During physical examination, a lump on the extensor surface of the middle phalanx of the right middle finger was found. Soft tissue ultrasound was performed, which indicated the presence of a worm in the cyst...

Simultaneous volar dislocation of distal interphalangeal (DIP) joint and volar fracture-subluxation of proximal interphalangeal (PIP) joint of the same finger has not been reported yet. A 19-year-old man was referred due to pain on the deformed left little finger after a ball injury. Radiographs showed volar dislocation of the DIP joint and dorsal lip fracture of the middle phalanx with volar subluxation of PIP joint of the little finger. This case was unique in terms of the mechanism of injury which was hyperflexion type in two adjacent joints of the same finger...

Osteoid Osteoma is benign bone forming tumor which commonly occurs in long bones of lower limb. Presence of these rare tumors in the distal phalanx of the digits of the hand is considered a rare phenomenon. In hand, they usually present as chronic pain, swelling, nail enlargement and increase in size of digit. Diagnosis is challenging with clinical examination and usual imaging modalities and often confused with glomus tumor, enchondroma, infection, trauma and rheumatic disease. Surgical excision of the tumor, if present in hand, is the treatment of choice that aids in coming to the exact diagnosis too...

BACKGROUND: Proximal interphalangeal joint (PIPJ) dorsal fracture dislocations (DFD) are challenging injuries. Treatment aims to achieve stability of the PIPJ after reduction so that early motion can be initiated. We studied how increasing articular destruction would affect post reduction stability and investigate the amount of traction and PIPJ flexion needed to maintain the reduction. METHODS: Increasing amounts (20%, 40% and 60%) of damage to the volar lip of the middle phalanx in cadaveric specimens were created to represent PIPJ DFD that were stable, of tenuous stability and frankly unstable...

BACKGROUND: Postoperative contracture as a major complication of surface replacement arthroplasty (SRA) remains an unresolved problem. Contracture after SRA can occur early in the postoperative period due to mechanical dysfunction, and tardy contracture where ROM declines with time postoperatively is also reported. METHODS: 13 fingers with degenerative osteoarthritis and two fingers with post-traumatic arthritis where SRA was performed using volar approach were involved...

Rock climbing is becoming an increasingly popular sport in Israel with more and more climbing walls being built in the cities and new routes being traced on cliffs around the country. Our account describes the case of a 15 years old climber with chronic pain (without trauma) in the 3rd finger of the right hand. A stress fracture, involving the proximal interphalangeal joint (SH3) of the middle phalanx, was diagnosed. The fracture healed following two months of rest with gradual return to activity. As this sport becomes more common, there is an increasing need for knowledge about the characteristic injuries, their diagnosis and treatment...

Myoepitheliomas (MEs) are uncommon tumours of the soft tissue with an intermediate biological behaviour and uncertain differentiation. Primary intra-osseous MEs are rare and occur predominantly in the axial and proximal appendicular skeleton in middle-aged patients. The morphological variation of the tumour cells and stromal metaplasia may cause considerable diagnostic confusion, especially when it occurs in an unusual location. A wide panel of immunohistochemical markers is required to exclude other histological mimics...

The hoof digital cushion is a complex structure composed of adipose tissue beneath the distal phalanx, i.e. axial, middle and abaxial fat pad. The major role of these fat depots is dampening compression of the corium underneath the cushion. The study aimed to determine expression of target genes and fatty acid profiles in the hoof of non-pregnant dry Holstein cows fed low (CON) or high-energy (OVE) diets. The middle fat pad of the hoof digital cushion was collected soon after slaughter. Despite the lack of effect on expression of the transcription regulators SREBF1 and PPARG, the expression of the lipogenic enzymes ACACA, FASN, SCD, and DGAT2 was upregulated with OVE...

The Wukongopteridae is an important pterosaur group discovered from Yanliao Biota, because it combines character states seen in non-pterodactyloid and pterodactyloid pterosaurs. So far, the Wukongopteridae contains three genera: Wukongopterus, Darwinopterus and Kunpengopterus; representing five species. Here we report on a new specimen, IVPP V 17959, that can be undoubtedly referred to the Wukongopteridae based on the presence of a confluent nasoantorbital fenestra, elongated cervical vertebrae (convergent with Pterodactyloidea) and a long tail enclosed by rod-like bony extensions of the zygapophyses...

A 5-year-old female Siamang (Hylobates syndactilus) in captivity sustained a displaced closed fracture of the proximal phalanx of the middle digit, resulting in finger deformity and hand functional disability. Anatomical reduction and stabilization of the fracture were obtained surgically using two multifilament wire sutures. The primate had a successful functional recovery.

Using magnetoencephalography (MEG), this study investigates the spatio-temporal dynamics of the multilevel cortical processing of somatosensory change detection. Neuromagnetic signals of 16 healthy adult subjects (7 females and 9 males, mean age 29 ± 3 years) were recorded using whole-scalp-covering MEG while they underwent an oddball paradigm based on simple standard (right index fingertip tactile stimulation) and deviant (simultaneous right index fingertip and middle phalanx tactile stimulation) stimuli gathered into sequences to create and then deviate from stimulus patterns at multiple (local vs...

The muscles of the anterior compartment of the forearm often exhibit anatomic variations. During dissection of the upper right limb of a preserved cadaver, morphological variations in the Palmaris longus and Flexor digitorum superficialis muscles were found. The Palmaris longus muscular fibers converged to a tendon that passed beneath the Flexor retinaculum, and inserted at the base of the middle phalanx of the fourth digit, replacing the tendon of Flexor digitorum superficialis. The Flexor digitorum superficialis was divided into two muscular heads: a digastric medial head giving tendons to the second and fifth digits, and a lateral head giving one tendon to the third digit...

Although more about the somatotopic mapping of fingers continues to be uncovered, there is lack of mapping attempts regarding the integration of within-finger and across-finger somatotopic coordinates in Broadmann area (BA) 3. This study aimed to address the issue by finding an inter-/intradigit somatotopic map with high-frequency (250 Hz) vibrotactile stimulation. Functional magnetic resonance imaging (fMRI) data were acquired while stimulation was applied to 3 phalanxes (distal [p1], intermediate [p2], and proximal [p3] phalanx) of 4 fingers (index, middle, ring, and little finger) for a total of 12 finger-phalanx combinations for a human...

A five month old Brown Swiss heifer calf (212 kg body mass) with severe left hind limb lameness, caused by a wound of the lateral digit was referred to the veterinary teaching hospital. The calf showed a score 4 of 5 lameness on the left hind limb. A scarified skin lesion with a fistula formation and purulent exudate was observed at the level of the proximal interphalangeal joint (PIJ) of the lateral digit of the left hind. The PIJ region and the lateral digit were severely swollen and painful. Ultrasonography showed a moderate anechoic effusion of the lateral digital flexor tendon sheet (DFTS) and a severe heterogeneous hypoechoic effusion with some small hyperechoic areas of the plantar and dorsal pouch of the PIJ...

OBJECTIVE: To investigate signs of central sensitization in a cohort of patients with chronic whiplash associated headache (CWAH). BACKGROUND: Central sensitization is one of the mechanisms leading to chronicity of primary headache, and thus might contribute to CWAH. However, the pathophysiological mechanism of CWAH is poorly understood and whether it is simply an expression of the primary headache or has a distinct pathogenesis remains unclear. Thus, the factors involved in the genesis of CWAH require further investigation...

Previous studies indicated that the fast-healer strain of MRL/MpJ-Fas(lpr)/J (MRL) mice demonstrated superior regenerative capabilities for digit wound healing and/or regeneration compared with the non-healer strain of C57BL/6 (C57) mice. These reports, however, mainly focused on morphological observations and analysis of gene expression with little attention on the role of angiogenesis in the amputated digits. By taking advantage of Laser Doppler Imaging and histological analysis, we examined the potential role(s) of angiogenesis in facilitating tissue regrowth/regeneration by comparing two strains of mice (MRL versus C57)...

REASONS FOR PERFORMING STUDY: Double plate fixation has been reported in a small number of horses with comminuted fractures of the middle phalanx. There are no published reports using this technique in the management of other injuries that destabilise the proximal interphalangeal joint (PIJ), including biaxial palmar/plantar eminence fractures and disruption of the palmar/plantar soft tissue support structures of the PIJ. Furthermore, there is a paucity of information on the long-term prognosis for horses undergoing double plate fixation to manage destabilising injuries of the PIJ OBJECTIVES: To further document the clinical use of double plate fixation for management of injuries to the PIJ resulting in palmar/plantar instability and compare these results with other methods of management...

UNLABELLED: Fingertip amputations are severe hand injuries. Their treatment must restore the sensation and metabolic activity needed for pain-free finger function. The cross-finger flap (CFF) can be used for this purpose. The goal of this study was to assess the long-term clinical outcome following use of this flap. METHODS: This was a retrospective analysis of 28 patients operated because of fingertip amputation: 16 type 3, 8 type 2 and 4 type 4. The CFF was harvested from an adjacent finger on the dorsal side of the middle phalanx down to the epitenon...
