Two unusual cases of isolated closed complex dislocation of the metacarpophalangeal joint of the third finger are presented. The single most important element preventing reduction was interposition of the volar plate between the proximal end of the phalanx and the head of the metacarpal, but the deep transverse ligament was also intimately involved in the entrapment mechanism. Such dislocations...

Erbium--169 was compared with triamcinolone hexacetonide in the topical treatment of 32 patients suffering from rheumatoid arthritis. Erbium--169 was injected into 83 and triamcinolone hexacetonide into 54 proximal interphalangeal or metacarpophalangeal joints. Both treatments produced alleviation of joint pain and swelling and improvement of grip strength. At every check-up (1--18 months) the ...

This case report discusses the reconstruction of an entire thumb metacarpal after a diagnosis of giant cell tumor of bone. The patient underwent excision of the entire thumb metacarpal, followed by interposition of a tricortical iliac crest bone graft and metacarpophalangeal and carpometacarpal joint arthrodeses. This option allowed salvage of the patient's native thumb with functional use as a...

Knuckle pads are rare harmless subcutaneous nodules that must be differentiated from joint disease of the proximal interphalangeal or rarely of the metacarpophalangeal joints as well as from other masses of the paraarticular tissues. We present a case of an otherwise healthy 36-year-old woman presenting with bilateral knuckle pads located at the dorsal aspect of the proximal interphalangeal joi...

It was hypothesized that the bioresorbable interposition implant might offer a viable alternative to conventional silicone implant arthroplasty in rheumatoid metacarpophalangeal joint destruction. A randomized clinical study was performed to compare a stemless poly-L/D-lactide copolymer 96 : 4 (PLDLA) implant with the Swanson silicone implant. Results in 52 patients (53 hands and 175 joints) at...

A fracture of the sesamoid bone of the hand is rarely seen. In most cases, it is strictly associated with the trauma. The patient complains of a long-lasting, due to unclear diagnosis, painful swelling of the joint with an inability to flex the affected finger. Limited blood supply makes the untreated fracture prone to avascular necrosis. Thus, it is extremely important to make a proper diagnos...

This paper details the construction of a Robotic Arm or manipulator with SCARA configuration and having DC Motors at its joints. There are two revolute joints present in the manipulator arm which helps the manipulator to be in RRP configuration. The DC Motors are given a pulse for a definite duration according to which they rotate by a certain angle.

Early repair of complete collateral ligament tears restores joint alignment, stability, and full passive range of motion.

background lesions in peripheral nerves are highly prevalent in the upper extremity. the present study compares different tendon transfer surgeries in patients with radial nerve palsy. methods fifty patients with radial nerve palsy were randomly selected among patients who referred to tehran 15th khordad hospital during 2006-2011. they were divided into two groups of 17 and 33 subjects. single ...

Dorsal dislocation of the metacarpophalangeal joint of the thumb is uncommon. We report the case of a 15-year-old patient with a complex dislocation of the left thumb who underwent open reduction after several attempts at closed reduction failed. At 2-month follow-up, full range of movement was regained; strength and pinch grip were comparable to that of the uninjured hand. The patient defaulte...
