Phalangeal osteochondroma: a cause of childhood trigger finger.

Trigger finger is uncommon among children and often caused by various lesions. We report a 5-year old girl who presented with chronic painless triggering of the right ring finger and normal X-ray. She underwent exploration of the finger flexor tendons and release of the A1 pulley. Lack of obvious pathology dictated further wound exploration which revealed a hidden osteochondroma of the proximal phalanx. We believe that adequate surgical wound exposure is necessary if no obvious cause of triggering could be seen in order to rule out an atypical osteochondroma even in the presence of normal X-rays.

Congenital flexion deformity of the middle finger and sagittal band hypoplasia.

PURPOSE: To report a congenital anomaly of the middle finger. METHOD: Nine patients (16 digits) are reported with congenital flexion deformity of the metacarpophalangeal (MCP) joint of the middle finger. Three patients (4 digits) had isolated deformities to the middle finger and in 6 the deformity was part of congenital ulnar drift (CUD) of the hand. Three patients had Freeman-Sheldon syndrome, 2 had nonsyndromic CUD, and 1 had arthrogryposis multiplex congenita. In CUD patients the middle finger had substantially greater flexion deformity of the MCP joint in comparison with other digits. Seven patients were treated surgically and 2 were treated nonsurgically. Five of the surgical patients had bilateral middle finger involvement. RESULTS: During surgery on 12 digits sagittal band hypoplasia of varying degrees was encountered in all patients and in all patients the extensor tendon of the middle finger was underdeveloped and often ulnarly displaced. Longitudinal imbrication of the remnants of the extensor tendon and centralizing the tendon if necessary by radial sagittal band reefing improved MCP joint flexion deformity. CONCLUSIONS: Congenital middle finger-in-palm deformity in our patients was caused by sagittal band and extensor tendon hypoplasia.

Longitudinal radiographic analysis of rheumatoid arthritis in the hand and wrist.

PURPOSE: To assess the longitudinal radiographic osseous changes of the wrist and hand other than interphalangeal joints in rheumatoid disease. METHODS: Serial wrist and hand x-rays in 96 patients with long-standing rheumatoid disease were reviewed. The average number of years between initial and most recent x-rays was 15.1. The Larsen scoring system was used to assess the degree and severity of joint involvement. We identified patterns of involvement in the wrist, thumb, and finger metacarpophalangeal (MCP) joints. RESULTS: The radioscaphoid and radiolunate joints had the earliest and most severe progression of all joints studied. Scaphoid erosions often were seen early (27%) and their presence was a predictor of progressive involvement. Ulnar styloid erosions commonly were seen as early isolated findings (25%). The distal radioulnar joint showed a rapid increase in Larsen score and was involved in 78% of patients on late x-rays. The thumb showed considerable late MCP joint disease that often led to boutonniere deformity and the trapeziometacarpal joint had the least rate of progression of all joints studied. The most severely and frequently involved MCP joints were the radial (index and middle), which also had the greatest increase in score over the span of the study. Finger MCP joint disease was observed to progress temporally in a predictable pattern: first radial MCP joints of the dominant hand, followed by the nondominant radial MCP joints, and last the ulnar MCP joints of the nondominant hand with small finger involvement preceding that of the ring finger. Of all MCP joints, the ring finger was least affected. CONCLUSIONS: This study clarified the longitudinal osseous radiographic changes of the wrist and hand (excluding interphalangeal joint) in rheumatoid disease.

Metacarpal fracture from archery: a case report.

We report a patient who sustained a hand injury while target shooting with a compound bow. An open metacarpal fracture occurred from the bow during the arming phase. This peculiar mechanism of injury has not been reported before. This report presents and discusses the mechanism of injury and reviews the literature on archery related injuries.

Flexor carpi radialis tendon rupture following chronic wrist osteoarthritis: a case report.

A patient is reported with a history of multiple tendon ruptures including biceps, flexor hallucis longus and achilles tendons. He presented with closed rupture of the flexor carpi radialis tendon following long standing tendonopathy and scapho-trapezio-trapezoid arthrosis. Non-operative treatment was elected because of low physical demands on the upper extremity. Early management of scapho-trapezio-trapezoid arthritis can prevent flexor carpi radialis tendon rupture.

Dupuytren's cord involving the septa of Legueu and Juvara: a case report.

A patient with Dupuytren's disease with involvement of the palmar fascial complex and digital contracture is described. A vertical cord had developed in the transverse ligament of the palmar aponeurosis fibers and the underlying septa of Legueu and Juvara. The cord was composed of a pretendinous band, transverse ligament of the palmar aponeurosis, and septum of Legueu and Juvara. The cord was attached deeply in the soft tissue confluence of the sagittal band, palmar plate, and interpalmar plate ligament. Involvement of the transverse ligament of the palmar aponeurosis and septa of Legueu and Juvara in Dupuytren's disease is rare. Understanding of the normal and pathologic fascial anatomy explains their simultaneous involvement and is necessary for complete ablation of the diseased tissue.

Radiographic analysis of pisotriquetral joint and pisiform motion.

We evaluated 45 wrists of normal volunteers fluoroscopically (15) and radiographically (30) to determine the optimal radiographic technique for profiling the pisotriquetral (PT) joint and to assess the pisiform motion. Real-time fluoroscopy showed that 4 views are necessary for optimal PT joint and pisiform visualization: wrist neutral/30 degrees forearm supination, wrist extension/30 degrees forearm supination, and active plus passive wrist flexion/45 degrees forearm supination with thumb abduction. Excursion percentage of the PT articular surface apposition on video imaging occurred 10% proximally in neutral, 20% distally in extension, and 40% proximally in flexion. Radiography showed pisiform excursion distally (2.5 mm) in extension and proximally with active (3 mm) and passive (2 mm) flexion. Pisotriquetral angle opened proximally (15 degrees ) in extension and distally with active (10 degrees ) and passive (5 degrees ) flexion. Pisotriquetral space averaged 1.5 mm in neutral, 1 mm in extension, 3.5 mm in active, and 3 mm in passive flexion. Pisohamate distance averaged 7.5 mm in neutral, increased to 8 mm in extension, and decreased to 2 mm with active and 0 mm with passive flexion. These views and parameters are useful for evaluating patients with PT joint injury and disease.

Anterior interosseous nerve syndrome: a case report.

A patient presented with anterior interosseous nerve syndrome that did not respond to nonoperative treatment. At surgery, nerve compression was found to be from an anomalous fibrous band of the flexor digitorum superficialis extending to the brachialis muscle fascia and separate from the normal arcade passing over the median nerve. Additionally, there was a venous ring encircling the nerve at the level of the anomalous arcade. The patient's muscle weakness recovered after nerve decompression and releasing the anomalous structures.
