Proximal interphalangeal (PIP) joint arthritis causes debilitating hand pain and instability leading to significant functional impairment. Arthrodesis remains the gold standard for treatment of PIP arthritis. We present a minimally invasive PIP arthrodesis that provides rigid fixation with a headless compression screw. Seven patients who presented to the senior author with PIP joint arthritis underwent PIP arthrodesis by minimally invasive technique. A 1 cm transverse incision is made over the PIP joint, incising skin, central band, and articular capsule...

The angulation of the equine fetlock determines the load of associated tendons and probably their predisposition for injuries. However, it is questionable how the individual toe conformation and tendon properties interact with the dorsal metacarpophalangeal joint angle (DMPJ). Data are needed for a tangible evaluation of the equine limb conformation for more specific orthopaedic treatment. The aim was to evaluate the correlation between the DMPJ, toe conformation and cross-sectional area (CSA) of both flexor tendons; the superficial digital flexor tendon (SDFT) and deep digital flexor tendon (DDFT)...

Rachel Pedreira, Brian H Cho, Angela Geer, Ramon A DeJesus
Background: The difficulties in surgical treatment of pilon fractures of the finger include fragment reconstitution and posthealing stiffness. In adults, external fixation with traction and early active range of motion (AROM)/passive range of motion (PROM) during healing is considered necessary for avoiding joint stiffness and attaining realignment. The authors present a unique approach to pediatric pilon fractures that uses open reduction and multivector external fixation with delayed AROM/PROM...

RATIONALE: Metachondromatosis (MC) is a very rare genetic disease, which is infrequently reported worldwide, which leads to osteochondroma and enchondromatosis. The disease has been shown to be associated with loss of function of the tumor suppressor gene "protein tyrosine phosphatase, non-receptor type 11" (PTPN11). PATIENT CONCERNS: A 12-year-old female was admitted to the hospital with pain due to an enlarged mass in her left fifth finger. DIAGNOSIS: Examination of the left hand by computed tomography (CT) revealed an expanding type of round and low-density lesion in the fifth proximal phalanx...

PURPOSE: Knowledge of anatomical landmark to pulley system of the thumb is essential in successful treatment of trigger thumb release either by percutaneous or by minimally invasive technique. Though surgical release of trigger thumb is done commonly, there is paucity of data in the literature regarding its surface landmarks. The purpose of this study is to identify palmar surface anatomical landmarks to the pulley system of the thumb. METHODS: Dissection was performed on 55 fresh frozen adult cadaveric thumbs...

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...

We described a laterally based cross-finger flap for reconstruction of soft tissue defects in the fingers. This modification enables coverage of volar or dorsal soft tissue defects at the distal, middle or proximal phalanx. From March 2015 to January 2017, a total of 12 patients (13 fingers) underwent soft tissue reconstruction of the fingers with a laterally based cross-finger flap. The flap dimensions ranged from 13 ×7 mm to 43 ×13 mm. Eleven of the 13 flaps survived completely. The two flap failures were attributed to injuries in the donor fingers, rendering the blood supply of the flaps unreliable...
