Repetitive stress fracture of the middle phalanx epiphysis is an injury specific to elite adolescent sport climbers. As sport climbing becomes increasingly popular in younger age groups, an increased number of these injuries have been reported in recent years. To date, treatment of these fractures has been nonsurgical, with strict rest and physiotherapy prescribed until fracture union. However, when these patients present in a delayed fashion with an established nonunion, nonsurgical treatment may fail, leading to disabling chronic pain and/or digital deformity in some cases...

BACKGROUND: Brachydactyly type A2 (BDA2) is an autosomal dominant disease characterized by the deformation of the middle phalanx of the second fingers and toes. It has been reported to be associated with three genes regulating the osteogenesis, including BMPR1B, GDF5 and BMP2. MATERIALS AND METHODS: 10 BDA2 patients and 7 unaffected individuals in a Chinese family were identified through clinical signs and radiographs. The mutation analyses of BMPR1B, GDF5 and BMP2 gene was performed in all the available family members and 100 control subjects...

Akio Sakamoto, Shuichi Matsuda
INTRODUCTION: Enchondromas are benign bone cartilaginous lesions predominantly seen in the hand, possibly leading to a pathological fracture. When the lesion expands to the whole phalanx, curettage through a small fenestration is difficult. To overcome the problem, soft-wire (cerclage wire) was used as a curette. Soft-wire is commonly used for a tension band wiring method for patellar or olecranon fractures. TECHNIQUE: Two representative cases are presented: one is a 43-year-old male with enchondroma in the middle phalanx of the left index finger, and the other is a 28-year-old female with enchondroma in the distal phalanx of the right thumb...

INTRODUCTION: Extension-block pinning represents a simple and reliable surgical technique. Although this procedure is commonly performed successfully, some patients develop postoperative extension loss. To date, the relationship between extension-block Kirschner wire (K-wire) insertion angle and postoperative extension loss in mallet finger fracture remains unclear. HYPOTHESIS: We aimed to clarify this relationship and further evaluate how various operative and non-operative factors affect postoperative extension loss after extension-block pinning for mallet finger fracture...

Regeneration of mammalian limbs is restricted to amputation of the distal digit tip, the terminal phalanx (P3). The adjacent skeletal element, the middle phalanx (P2), has emerged as a model system to investigate regenerative failure and as a site to test approaches aimed at enhancing regeneration. We report that exogenous application of bone morphogenetic protein 2 (BMP2) stimulates the formation of a transient cartilaginous callus distal to the amputation plane that mediates the regeneration of the amputated P2 bone...

A mallet finger is a flexion deformity of a finger at the distal interphalangeal joint due to an injury of the extensor mechanism at the base of the distal phalanx. Most common in middle-aged men, injuries in the pediatric population are less common and rare in toddlers. We describe a case of missed mallet finger and its subsequent treatment in a female toddler.

The mismatch negativity (MMN) reflects the early detection of changes in sensory stimuli at the cortical level. The mechanisms underlying its genesis remain debated. This magnetoencephalography study investigates the spatio-temporal dynamics and the neural mechanisms of the magnetic somatosensory MMN. Somatosensory evoked magnetic fields elicited by tactile stimulation of the right fingertip (Single), tactile stimulation of the right middle phalanx and fingertip (Double) or omissions (Omitted) of tactile stimuli were studied in different paradigms: in oddballs where Double/Omitted followed a sequence of four Single, in sequences of two stimuli where Double occurred after one Single, and in random presentation of Double only...

PURPOSE: To demonstrate which structures of the extensor mechanism create a boutonniere deformity, when damaged, in a cadaver model. An analysis of how damage to these anatomical structures affects the biomechanical performance of the extensor mechanism was also performed. METHODS: We secured 18 fresh cadaveric hands onto an apparatus consisting of a computer-controlled motor and tensiometer attached in series to the extensor communis tendon of the ring and middle digits...

Fungal osteomyelitis of the hand is rare with limited evidence-based literature to guide diagnosis and management. We report a case of disseminated cryptococcal osteomyelitis in the middle phalanx from a pulmonary fungal infection in a patient with a history of lymphoplasmacytic lymphoma. Although rare, cryptococcosis should be considered in the differential diagnosis of aggressive lytic lesions with bone pain and associated large soft tissue masses, especially in the immunosuppressed host.

OBJECTIVE: To identify possible correlations between skin blood perfusion (BP) and dermal thickness (DT) in different skin areas of systemic sclerosis (SSc) patients. METHODS: Sixty-two SSc patients, according to 2013 EULAR/ACR criteria, and 62 healthy subjects (CNT) were enrolled. Skin BP was analysed by laser speckle contrast analysis (LASCA) at the level of dorsum of the middle phalanx of the third fingers, dorsal aspect of the hands and zygoma. DT was assessed by both skin high frequency ultrasound (US) and modified Rodnan skin score (mRSS) in the same above reported areas...

Syndactyly is a cutaneous and/or bony digital malformation with possible webbing of adjacent fingers or toes and uni- or bilateral occurrence. We report an 84-year old woman with a novel non-syndromic congenital malformation of her left hand. Clinical examination showed that she only had four digits. Radiograph of the hand revealed synostosis of the second and third proximal phalanx, resulting in a triangular shaped bone with relatively normal articulations at both ends. The phalangeal base of the fused finger tapers distally and is broader than the middle phalangeal bases of the ring and little finger...

We report the results of physiolysis of the epiphyseal bracket combined with free fat grafting for the treatment of delta phalanx. Thirteen cases (five patients) were included. Mean patient age was 6.6years (range, 4-9). The patients underwent physiolysis in which the epiphyseal bracket was cut and replaced with a free fat graft. The angle between the long axis of the proximal and distal phalanges and the ratio between the width and length of the affected middle phalanx were evaluated on plain radiographs. The range of motion in the fingers was also evaluated...

A glomus tumor is an uncommon, predominantly benign, neoplastic lesion that primarily involves a thermoregulatory microvascular apparatus, the glomus body. Although these lesions can occur anywhere in the body, the subungual tissue of the hand represents the most common presentation site. Glomus tumors are not often encountered in the foot. Symptoms traditionally include the classic triad of pain, pressure, and cold sensitivity. This case report describes a variant location for a glomus tumor in the subcuticular tissue adjacent to the medial middle phalanx of the second toe...

We report a unique case of an epithelioid hemangioma of the third middle phalanx in which the lesion replaced the phalanx, became symptomatic, and then required resection, bone grafting, and joint arthroplasty. To the best of our knowledge, this is the first report of an epithelioid hemangioma in the toe that was treated using this approach.

Recurrent dislocation is not common in small joints. This report presents a recurrent dislocation of the proximal interphalangeal joint of the ring finger in a 23-years-old man. Recurrent dislocation was addressed successfully by repairing the avulsed volar plate to the base of the middle phalanx, followed by 6 weeks of splint immobilization.

Malunion at the shaft of the middle phalanx yields less functional problems compared with malunion at the shaft of the proximal phalanx and metacarpal bones. In the present report, the patient sustained a minimally displaced fracture at the distal portion of the distal middle phalanx of the ring finger spraining the finger during playing flag football. Fracture was treated conservatively and fracture union was completed. However, the patient complained of functional problems in activities of daily living due to the malrotational deformity of the finger...
