Kingshuk Chatterjee, Sankha Koley, Bhushan Madke
A 10-year-old girl presented with three asymptomatic raised lesions over the dorsal aspect of her left index finger present for the past 7 years. On examination, there were three skin-colored nodules overlying the middle and distal phalanx of her left index finger, without any attachment to the underlying structures (Figure 1) The nodule over the distal phalanx was the largest with a cobblestone-like surface. All the nodules were firm to touch. Cutaneous, mucosa, hair, nails, and systemic examinations were within normal limits...

Kirschner wires (K-wires) are widely used for fixation of fractures and dislocations in the hand as they are readily available, reliable, and cost-effective. Complication rates of up to 18% have been reported. However, K-wire breakage during removal is rare. We present one such case illustrating a simple technique for retrieval. A 35-year-old male presented with a distal phalanx fracture of his right middle finger. This open fracture was treated with K-wire fixation. Postoperatively, he developed a pin site infection with associated finger swelling...

As an alternative to amputation of the little finger, we report here seven cases of shortening arthrodesis carried out by resecting the middle phalanx and proximodistal interphalangeal (PDIP) arthrodesis. Our cohort consisted of 6 males and 1 female (58years average age), with a stiff little finger secondary to Dupuytren's disease or trauma. All fingers were approached dorsally; after resection of the middle phalanx and decortication of the subchondral bone, fusion of the remaining phalanges was performed using an intramedullary self-breaking screw-pin...

: Unstable distal phalanx fractures are typically treated by pinning of the distal phalanx or the distal interphalangeal joint (DIP). Complications include unstable fixation, K-wire migration, septic arthritis and osteoarthritis. To limit these complications, we wanted to explore the benefits of using locked extra-articular DIP pinning. The cohort consisted of 12 patients (mean age 36.3 years) who had an extra-articular (6 cases) or intra-articular distal phalanx fracture (6 cases). All patients were treated surgically with a construct consisting of two connected K-wires: one was placed inside the shaft of the distal phalanx and the other was placed perpendicular to the middle phalanx...

: The primary aim of this study was to assess the clinical and radiological results after hemi-hamate resurfacing arthroplasty in patients with acute or chronic unstable fractures of the base of the middle phalanx and to describe technical features that can facilitate the surgical procedure. Hemi-hamate arthroplasties were done in 19 patients (mean age 39 years) with an isolated fracture at the base of the middle phalanx that involved more than 40% of the articular surface. We assessed ten chronic cases (treated >6 weeks after fracture) and nine acute ones (<6 weeks) at a mean of 24 months...

BACKGROUND/OBJECTIVES: The use of the sole third finger middle phalanx for a maturational method has been proposed but not fully investigated. Herein, the diagnostic reliability of an improved five-stage third finger middle phalanx maturation (MPM) method in the identification of mandibular growth peak has been investigated. SUBJECTS/METHODS: From the files of the Burlington Growth Study, 35 subjects (20 males, 15 females) with at least 7 annual lateral cephalograms taken from 9 to 16 years were included...

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...

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...
