Scapholunate (SL) instability is the most common form of carpal instability. Imaging (especially radiography) plays an important role in the staging, management, and postoperative follow-up of SL instability. In the final stage of SL instability, known as scapholunate advanced collapse, progressive degenerative changes occur at the carpal level. The goals of this article are to review the surgical options available for addressing the different stages of scapholunate advanced collapse, along with an emphasis on normal postoperative imaging and complications associated with each surgical option...

Clinical assessment of the hand is important for diagnosing underlying hand disorders. Using a case study approach, the clinical assessment for three disorders of the hands is presented: trigger finger (stenosing tenosynovitis), carpal tunnel syndrome, and ulnar-sided wrist injury (styloid impingement). We assess the annular one pulley and finger range of motion for patients with trigger finger. To diagnose for carpal tunnel syndrome, assessment for Tinel's sign, Phalen's sign, abductor pollicis brevis muscle bulk, two-point discrimination, and obtaining a nerve conduction study are performed...

The aim of this study was to compare the value of superb microvascular imaging (SMI) in carpal tunnel syndrome (CTS) with that of color Doppler ultrasonography (CDUS) and power Doppler ultrasonography (PDUS).Fifty patients with symptomatic CTS and 25 healthy volunteers were enrolled. The cross-sectional area (CSA), CDUS score, PDUS score, and SMI score of the median nerve (MN) at the carpal tunnel were recorded. The value of different ultrasonography (US) diagnostic strategies was calculated.The blood flow display ratio in the MN of the healthy volunteers had no statistical difference between CDUS, PDUS, and SMI (20%, 32%, and 48%, respectively, P >...

BACKGROUND: We examined the relationship between lunate morphology (type 1 without a medial facet; type II with a medial facet) and dorsal intercalated segmental instability (DISI) in patients with scapholunate ligament injuries. We tested the primary null hypothesis that there is no relationship between lunate morphology and development of DISI. Secondary analysis compared the agreement of classifying lunate morphology based on the presence of a medial lunate facet, capitate-to-triquetrum (CT) distance, and magnetic resonance imaging (MRI)...

Chameleon species have recently been adopted as models for evo-devo and macroevolutionary processes. However, most anatomical and developmental studies of chameleons focus on the skeleton, and information about their soft tissues is scarce. Here, we provide a detailed morphological description based on contrast enhanced micro-CT scans and dissections of the adult phenotype of all the forelimb and hindlimb muscles of the Veiled Chameleon (Chamaeleo calyptratus) and compare these muscles with those of other chameleons and lizards...

BACKGROUND: Although median nerve neuropathy and carpal tunnel syndrome (CTS) are known complications of both untreated and acutely treated distal radius fracture, median neuropathy after correction of distal radius malunion is not commonly reported in hand surgery literature. We describe a patient with severe CTS after corrective osteotomy, open reduction internal fixation (ORIF) with a volar locking plate (VLP), and bone grafting for distal radius malunion. METHODS: We report a case of severe acute CTS as a complication of corrective osteotomy with bone grafting for distal radius malunion...

BACKGROUND: Distal scaphoid excision is one treatment option for osteoarthritis of the scaphotrapeziotrapezoid (STT) joint following failure of conservative measures. Potential complications of this procedure include injury to the carpal ligaments, cartilage, and radial artery. METHODS: A single case was identified by the senior author, and the medical record was reviewed for surgical notes, progress notes, and radiographs. RESULTS: A 68-year-old male sustained ruptures of the flexor digitorum superficialis (FDS) and flexor digitorum profundus to the index finger 3 years following a distal scaphoid excision for symptomatic STT osteoarthritis...

Solitary metastasis of a carcinoma to carpal bone is extremely rare. Metastases of renal cell carcinoma (RCC) usually occur in a multiple fashion and there has been no report to date of a solitary metastasis to trapezium from RCC. The tumor was excised and reconstructed with iliac bone transplantation. 2 years and 6 months after surgery, there is no local recurrence with minimal functional loss.

Osteochondroma is the most common benign bone tumor. Lesions occurring at the carpal bones are extremely rare. There are very few cases of osteochondroma at the trapezium had been reported in the English literature. We reported a 47-year-old patient with an osteochondroma of the left trapezium presented with painful snapping of abductor pollicis longus tendon.

Trigger finger is a mechanical problem with many etiological factors as possible causes, such as diabetes mellitus, carpal tunnel syndrome and repetitive finger movements. Although it can afflict anyone, it is much commoner in middle-aged women than men and the most commonly involved digit is reported to be the thumb. The diagnosis is mainly based on clinical symptoms during examination and first-line treatment is conservative with splinting and corticosteroid injections. Surgical open release is the "gold standard" of trigger finger treatment because it allows more careful inspection of the surgical area and is highly effective with low complication rates...

BACKGROUND: Several studies report that psychological factors are associated with outcomes of carpal tunnel release. However, interpretation of the association is difficult as there are diverse outcome parameters and patient expectations are different. We performed a systematic review to assess the relationships between psychological factors and the various outcome parameters. METHODS: We identified 611 papers and selected 8 papers that fit the inclusion criteria...

BACKGROUND: The purpose of this study was to identify predictive factors of poor response to intra-flexoral sheath corticosteroid injection, as well as to identify factors associated with patients' decisions to undergo surgical treatment. METHODS: Data from 112 patients who received steroid injection treatment for trigger finger were reviewed retrospectively. Logistic regression was used to assess the prognostic value of factors assumed to affect prognosis (age, sex, underlying disease, history of illness, presence of carpal tunnel syndrome, multiple digit involvement, and pre- and post-operative disability scores)...

BACKGROUND: Congenital carpal coalition is usually seen as an incidental finding. The incidence of carpal coalition has been reported from 0.1 to 9.5 %; highest incidence has been reported in people of African descent. The purpose of our study is to evaluate the incidence and subtypes of carpal coalition in an Asian population. METHODS: Review of the radiographs of the patients in our distal radius fracture database from 2009 to 2014 was conducted to determine the incidence and type of carpal coalition...

BACKGROUND: Os styloideum describes an accessory carpal ossicle between the trapezoid, the capitate, and the second and third metacarpals. Injuries to this tissue have been described as part of the carpal boss syndrome. While the etiology of os styloideum remains uncertain, it may represent a physiologic response to altered loading forces in the wrist, similar to the development of cam-type deformity in the hips of ice hockey players or the Bennett lesion in the shoulders of baseball pitchers...

A 72-year-old man presented with persistent oligoarthritis and positive results for rheumatoid factor and was suspected of having rheumatoid arthritis (RA). However, the musculoskeletal ultrasonography (MSUS) findings were not consistent with those of typical RA. He had undergone surgery for carpal tunnel syndrome, which allowed both histopathological and microbiological examinations to be performed. A synovial tissue culture was positive for Sporothrix schenckii, and he was diagnosed with sporotrichal tenosynovitis...

INTRODUCTION: Individuals differ in forearm length. As microstructure differs along the radius, we hypothesized that errors may occur when sexual and racial dimorphisms are quantified at a fixed distance from the radio-carpal joint. METHODS: Microstructure was quantified ex vivo in 18 cadaveric radii using high resolution peripheral quantitative computed tomography and in vivo in 158 Asian and Caucasian women and men at a fixed region of interest (ROI), a corrected ROI positioned at 4...

INTRODUCTION: Prior studies reported higher wrist ratios (WR) related to carpal tunnel syndrome (CTS), but have not assessed effect modification by obesity and may have inadequately controlled for confounders. METHODS: Baseline data of a multicenter prospective cohort study were analyzed. CTS was defined by nerve conduction study (NCS) criteria and symptoms. RESULTS: Among the 1,206 participants, a square-shaped wrist was associated with CTS after controlling for confounders (prevalence ratio = 2...

Carpal bone fusions for secondary reconstruction are still indispensable despite state of the art diagnostic tools and modern treatment techniques for wrist lesions. The former fusions stabilize the wrist and enable sufficient residual carpal mobility. Pain can be reduced significantly by arthrodesis of destroyed joints and the progress of osteoarthritis may be stopped or delayed. This review presents commonly used fusions with their inherent indications, contraindications and complications.
