..The dorsoradial capsulodesis is a reasonable reconstructive option for chronic TM joint instability and subluxation...

..The complication rate after ligation of ulnar polydactyly of the hand was 23.5 percent. The two main complications were tender or unacceptable nubbins and infections...

..To examine anatomically and radiographically the ligaments stabilizing the pisotriquetral (PT) joint and to determine the contribution of each ligament to the stability of this joint...

..This should be taken into account in future epidemiological and outcome studies...

..Some of these can be utilized as an adjunct to surgical treatment rather than a replacement for it. The most commonly used nonoperative treatment methods are briefly reviewed...

..We sought to define these terms and investigate the distribution and frequency of dorsal knuckle pads and dorsal nodules in the normal volunteers and in DD patients...

..The purpose of this study was to identify regions of the entire genome (chromosomes 1-23) associated with the disease by performing a genome-wide association scan on DD patients and controls...

..This study provides insight into the etiology of piso-triquetral joint instability and dysfunction...

..Improved appearance, hygiene, and a certain degree of upper extremity function, regardless of cognitive abilities, can be expected following arthrodesis for severe spastic wrist deformity...

..Pisiformectomy with preservation of the soft tissue confluence remains the treatment of choice for severe PLC syndrome that does not respond to nonoperative treatment...

..Bilateral wrist arthrodeses does not seem to adversely affect function of the upper extremity in spite of abnormal grip strength and upper extremity range of motion...

..Extensor tendon instability in this case was due to the combined forces of the extrinsic and intrinsic muscles on the retinacular system of the extensor mechanism...

..Our findings explain the propensity for radial sagittal band injuries and suggest that the sagittal band is the primary stabilizer of the extensor digitorum at the metacarpophalangeal joint...

..Two adolescents with bilateral radial clubhand, hypoplastic thumbs, and thrombocytopenia are reported. Ulnocarpal arthrodesis provided these patients with pain-free wrists and improved their function...

..Patients with proximal stenosing tenosynovitis may have an associated distal stenosing tenosynovitis that if overlooked may cause persistence of symptoms after surgical treatment...

..These results are consistent with the hypothesis that the basement membrane plays a role in regulating the epithelial-mesenchymal interaction responsible for induction of limb outgrowth...

..Hyperextension was prevalent among women on hormone-replacement therapy, including 3 patients in whom these deformities recurred in spite of attempts to stabilize their joints during surgery...

....

..Awareness of the risks and factors associated with hand injuries during hand surgery and adopting intraoperative measures are important strategies for preventing these potentially serious and life-threatening accidents...

..Surgical excision of the lesion revealed a lipoma overlying a bony exostosis or osteolipoma of the hand. Post-operatively, the patient's symptoms resolved and she had no recurrence of the tumor...

..V-Y slide of the extensor origin has low morbidity, does not violate the joint space or lateral stabilizing ligaments of the elbow, allows adequate release, and has a high rate of satisfaction...

..Metallic implants, including total joint prostheses and those utilizing a spacer concept, have been used with some success. Indications, technical consideration, and potential complications of these implants are discussed...

..The modified rerouting technique can be done with a single incision and allows easy adjustment of tension...

..The anomalous thenar muscle most probably represents duplication of the abductor pollicis brevis...

..Anterior submuscular transposition of the ulnar nerve in this series provided satisfactory subjective outcome, relief of symptoms and adequate decompression of the ulnar nerve at the elbow...

..These results suggest that Dupuytren's fibroblasts can acquire smooth muscle characteristics and that the acquisition of a smooth muscle-like phenotype correlates with increased contractility...

....

..Even 1 mm of TT shortening will seriously restrict DIP joint flexion...

..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...

..To study the anatomy and kinematics of the thumb sagittal band (SB) and the influence of simulated injury on the stability of the extensor pollicis longus (EPL) tendon...

..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...

..The thin nature and proximity of the TT to the nail matrix must be kept in mind during surgery. Knowledge of the TT anatomy is necessary for further study of its kinematics and pathology and for diagnosis and management of its disorders...

..CONCLUSIONS: Awareness of the anatomy of deep retinacular structures of the hand is important for surgical exposure in this area and possible involvement in conditions such as Dupuytren's disease...

..Its presentation, although seemingly rather constant, is actually extremely variable, depending on which structures are involved. A thorough knowledge of palmar fascial anatomy is essential to the understanding of Dupuytren's disease...

..CONCLUSIONS: Congenital middle finger-in-palm deformity in our patients was caused by sagittal band and extensor tendon hypoplasia...

..Peripheral i.v. line complications are not uncommon and can result in morbidity and increased health care costs from prolonged hospitalization, extended use of i.v. antibiotic therapy, and surgical intervention...

..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...
