Superficial digital flexor tendon (SDFT) of the bovine hindlimb originates from the caudolateral aspect of the distal femur and finally inserts onto the plantar aspect of the middle phalanges. In the present study, morphology and morphometry of the bovine SDFT at the muscle-tendon junction (MTJ), middle metatarsus (mM) and tendon-bone interface (TBI) were investigated. Cross-sectional morphology at the three regions of SDFT were oval, semioval and ring-formed, respectively. Significant difference in cross-sectional area was found only between MTJ-mM and mM-TBI (P<0...

OBJECTIVE: Systemic sclerosis (SSc) is a connective tissue disorder of unknown etiology, with heterogeneous clinical manifestations and chronic and often progressive course. The diffuse cutaneous form of SSc (dcSSc) is characterized by thickening of the skin (scleroderma) and distinctive involvement of multiple internal organs. Patients with limited cutaneous SSc (lcSSc) generally have long-standing Raynaud's phenomenon before other manifestations of SSc appear. Over the last decade the Interest of adipose-derived cell therapy in regenerative medicine has increased continuously...

Digital sesamoids are found in the metapodial-phalangeal joints of most mammals and quadrupedal tetrapods, yet their functional significance is still unclear. During primate evolution, a slight decline in their frequency has been associated with brachiation in gibbons, followed by a quasi-complete absence in orangutans then a slight resurgence occurred in gorillas and chimpanzees. Simultaneously, forearm muscles showed a progressive division in hominoid evolution towards a more "individualistic" musculature yielding more mobility and independence to some fingers...

Human exhibits the most dexterous manual manipulation among the anthropoids. The sophisticated dexterity of human hand has been linked to its distinctive morphology compared to the nonhuman anthropoids. The human hand is derived from the ancestral hands after longtime evolution. However, there are more possible morphologies that the hands could take during the evolutionary process. It remains unknown whether better hands for manipulation than the human hand exist among these possible hands. To answer the question, the relationship between the manipulative capability and hand morphology need to be investigated in the region of more possible hands...

CASE: We present an unusual case of unilateral congenital quintus valgus of the left foot (congenital lateral deviation of the fifth [little] toe) in a 1.5-year-old boy. The child had no other congenital malformations. Radiographs revealed the abnormal presence of 2 accessory phalangeal ossicles in the fourth web space, leading to lateral deviation of the fifth toe. Remarkably, the ossicles of the middle and distal phalanges of the fifth toe were absent. Surgical excision of the accessory ossicles was performed, and correction of the deformity was achieved...

Swan neck deformity is a hyperextension of the proximal interphalangeal (PIP) joints and flexion of the distal interphalangeal (DIP) joints. Claw hand is a hyperextension of the metacarpal joints and flexion of the PIP joints, accompanied by reduced motor strength. A 23-year-old female, who was released from leprosy treatment, presented with a bend of the second to fifth fingers of both hands. There was hyperextension of the PIP joints and flexion of the DIP joints from the second to fifth fingers of both hands, thickening of the ulnar nerves, and hypoesthesia without motor impairment of the fourth and fifth fingers of both hands...

BACKGROUND: Malunion of phalangeal and metacarpal bones are often associated with impairment of hand function and pose a challenging task for treating surgeons in most cases. When applicable, corrective osteotomy is the treatment of choice, where the affected bone is cut to correct malalignment using chisels or saws. The use of these instruments is associated with several drawbacks especially in hand surgery. We aimed to determine whether a multiple drill-hole (MDH) osteotomy technique was suitable for performing corrective osteotomies of metacarpal and phalangeal bones...

There are no accepted methods to grade bone marrow oedema (BMO) and fracture on magnetic resonance imaging (MRI) scans in Charcot osteoarthropathy. The aim was to devise semiquantitative BMO and fracture scores on foot and ankle MRI scans in diabetic patients with active osteoarthropathy and to assess the agreement in using these scores. Three radiologists assessed 45 scans (Siemens Avanto 1.5T, dedicated foot and ankle coil) and scored independently twenty-two bones (proximal phalanges, medial and lateral sesamoids, metatarsals, tarsals, distal tibial plafond, and medial and lateral malleoli) for BMO (0-no oedema, 1-oedema < 50% of bone volume, and 2-oedema > 50% of bone volume) and fracture (0-no fracture, 1-fracture, and 2-collapse/fragmentation)...

BACKGROUND: Clubbing is associated with poor prognosis and is variably present in patients with idiopathic pulmonary fibrosis (IPF), but is also seen in other fibrotic interstitial lung diseases (ILDs). Little is known about the best methodology to assess clubbing in ILDs and, hence, the prevalence and clinical utility and clinical significance of clubbing. We therefore aimed to evaluate the agreement between different clubbing assessment methods in patients with fibrotic ILDs. Additionally, we assessed the prevalence of clubbing in different fibrotic ILDs and related clubbing to disease severity and quality of life...

Humans exhibit a remarkable ability to discriminate variations in object volume based on natural haptic perception. The discrimination thresholds for the haptic volume perception of the whole hand are well known, but the discrimination thresholds for haptic volume perception of fingers and phalanges are still unknown. In the present study, two psychophysical experiments were performed to investigate haptic volume perception in various fingers and phalanges. The configurations of both experiments were completely dependent on haptic volume perception from the fingers and phalanges...

Hallux valgus is considered the most common musculoskeletal deformity, with a prevalence of 88%. There are more than 130 surgical techniques for its treatment; currently, percutaneous ones are popular; however, they do not take into account the metatarsal-phalangeal correction angle. The aim of this study is to propose a modified technique for the correction of the percutaneous metatarsal-phalangeal and inter-metatarsal angles and to evaluate its clinical and radiological results. MATERIAL AND METHODS: An experimental, prospective and longitudinal study in 10 patients with moderate to severe hallux valgus according to the classification of Coughlin and Mann were collected; the results were evaluated with the AOFAS scale at 15, 30, 60 and 90 days...

Extension of the fingers is a complex act. Boutonnière deformity is defined by flexion at the proximal inter-phalangeal (PIP) joint and hyperextension at the distal interphalangeal (DIP) joint due to disruption of the central slip of the extensor tendon. Swan neck deformity is defined by hyperextension at the PIP joint and flexion at the DIP joint, and the pathology is divided into intrinsic, extrinsic, and articular. The deformities are a result of imbalance of the tendons and ligaments in the fingers. Treatment is depending on the underlying cause and includes surgery and non-operative treatment...

Introduction: Several diseases affect the forefoot bones. Relative dimensions of the forefoot bones are important considerations for preoperative and postoperative assessment of surgeries. The choice of a particular surgery over another can also be made if the surgeon knows the length to which a bone needs to be lengthened or shortened in comparison to other bones of the forefoot. Aim: To measure the dimensions of the metatarsals and phalanges on standardized radiographs and to determine possible correlations amongst them...
