PURPOSE: Biphalangealism of the toes is an exclusively human phenomenon. The aim of this study was to evaluate the development of the lateral toes in childhood by following the ossification pattern of the phalanges. METHODS: Foot radiographs of 913 adults have been evaluated for biphalangealism of 3rd to 5th toe. The pediatric group, aged 6-15 years of age, was assessed for the number of ossification centers in the foot. RESULTS: In adults, the mean prevalence of biphalangealism in the 5th toe was 41...

REVIEW

Fracture dislocations of the proximal interphalangeal (PIP) joint of the finger are often caused by axial load applied to a flexed joint. The most common injury pattern is a dorsal fracture dislocation with a volar lip fracture of the middle phalanx. Damage to the soft-tissue stabilizers of the PIP joint contributes to the deformity seen with these fracture patterns. Unfortunately, these injuries are commonly written off and left untreated. A late-presenting PIP joint fracture dislocation has a poor chance of regaining normal range of motion...

OBJECTIVE: The fractured base of the middle phalanx was reconstructed in 13 patients using an osteochondral transplant from the carpometacarpal joint surface of the hamate bone. The goal was to restore joint stability with preservation of mobility. Indications were acute and missed isolated destruction of the palmar middle phalanx base ≥ 30 %. Contraindications were destruction of the head of the proximal phalanx, advanced chondropathy of the head of the proximal phalanx, and extensive soft tissue injury with loss of skin coverage for the proximal interphalangeal joint...

New developments in primary tendon repair over the past decades include stronger core tendon repair techniques, judicious and adequate venting of critical pulleys, followed by a combination of passive and active digital flexion and extension. During repair, core sutures over the tendon should have sufficient suture purchase (no shorter than 0.7 to 1 cm) in each tendon end and must be sufficiently tensioned to resist loosening, forming gaps. Slight or even modest bulkiness in the tendon substance at the repair site is not harmful, though marked bulkiness should always be avoided...

Multiple methods have been described for treating unstable proximal and middle phalangeal fractures. Irrespective of using an open or closed technique of fixation, stiffness and extensor lag at the proximal/distal interphalangeal joint almost always occur. This issue can be avoided by allowing the patients to mobilize the fingers out of plaster or splint as early as possible from the day of surgery. We describe a technique of intramedullary percutaneous fixation of extra-articular proximal and middle phalanx fractures allowing immediate mobilization of fingers, concurrent stabilization with progressive healing and thus preventing such complications...

BACKGROUND: Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder mainly characterized by cutaneous poikiloderma, sparse hair, short stature and skeletal defects. Deleterious mutations in the RecQ-like DNA helicase type 4 (RECQL4) gene have been detected in approximately two-thirds of RTS cases. METHODS: Three Chinese patients from two unrelated families were enrolled for clinical evaluation. Targeted next-generation sequencing (NGS) using a custom panel consisting of 705 short-stature-related genes was performed for the probands...

We describe 4 cases of irreducible volar rotatory subluxation of the proximal interphalangeal (PIP) joint of the finger that required open reduction. All of the patients had radiographically proven (in lateral-view radiographs) volar rotatory subluxation of the PIP joint, without fracture. The causes of irreducibility were interposition of the lateral band about the condyle of the middle phalanx in 2 cases, interposition of the collateral ligament in 1 case, and scarring of the injured central slip in 1 case...

PURPOSE: It is a common belief that extension of the metacarpophalangeal (MCP) joint of the finger is achieved via the sagittal bands acting as a sling or lasso to attach the extensor tendon to the base of the proximal phalanx. The aim of this study was to test the hypotheses that (1) division of the sagittal bands reduces extension force or torque of the MCP joint, and (2) division of the extensor tendon distal to the sagittal band will not affect the extension force or torque of the MCP joint...

Giant cell tumors of the tendon sheath (GCT-TS) are one of the most common tumors of the hand, along with ganglions. However, occurrence in the toes is far less common. Here we present a rare case of GCT-TS at the middle phalanx level of the flexor digitorum longus tendon sheath. Magnetic resonance imaging showed low intensity both on T1 and T2 weighted images. To the best of our knowledge, our case is the first report of a GCT-TS arising at the middle phalanx level of the flexor digitorum longus tendon sheath of the fourth toe...

This study describes a radiographic survey of the anatomical development of the distal extremity of the manus in the donkey from 0 to 2 years of age. The right distal limb of 10 donkey foals, born in the spring of 2012, underwent radiographs every month for the first 6 months of age and every 3 months during the following 18 months. Latero-medial radiographs with and without barium marker at the coronary band and dorso-palmar radiographs with both front feet in weight bearing were obtained. The distal physis of the third metacarpal bone and the proximal physis of the proximal phalanx (phalanx proximalis) were closed at the mean age of 18...

Introduction: In the modern era, identification and determination of age is imperative for diversity of reasons that include disputed birth records, premature delivery, legal issues and for validation of birth certificate for school admissions, adoption, marriage, job and immigration. Several growth assessment parameters like bone age, dental age and the combination of both have been applied for different population with variable outcomes. It has been well documented that the chronological age does not necessarily correlate with the maturational status of a child...

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...

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...
