Metacarpophalangeal joint arthroplasty

MCP joint arthroplasty is designed to relieve pain, restore function, and correct deformity to provide an aesthetic improvement to the hand. Many prosthetic designs have been introduced over the last 40 years, and these may be grouped into one of three basic designs the hinged prosthesis, the flexible prosthesis, and the third-generation prosthesis. The early, hinged designs included the Brannon and Klein, Flatt, Griffith-Nicolle, Schetrumpf, Schultz, Steffee, St. Beorg-Buchholtz, KY alumina,...

Metacarpophalangeal joint arthrodesis

Arthrodesis of the finger MP joint is most specifically indicated in preference to resection arthroplasty for isolated joint arthrosis in the border digits (index or small) or in a manual laborer. A position of 20 to 30 has been recommended 11 . In general, however, a procedure that retains some motion is preferable however, when stability and pain relief at the MP joint are provided by fusion, functional patterns of prehension can be restored (see Fig. 1). In the absence of ligamentous...

Arthroplasty

Arthroplasty of the MP joint is a useful technique in the attempt to maintain thumb length, relieve stress about the CMC joint, and improve positioning of the thumb tip 15 . Arthro-plasty of the MP joint of the thumb is relatively easy to accomplish, because the MP joint anatomy approximates that of a simple hinge 15 . Brannon and Klein reported the first prosthetic MP joint in 1959 13 . This early prosthesis was a hinged replica of the MP joint, first constructed of stainless steel and then...

Additional advocacy on behalf of suspensionplasty

Advanced basal joint disease implies end-stage degeneration of the TM joint (stages 2-4), salvageable only by a procedure that removes or replaces the entire articular surface. Although TM fusion provides superlative pain relief and outcomes potentially comparable to ligament reconstruction, mobility is limited, and abnormal wear at adjacent unfused joints can develop 9,10 . Simple trapezium excision avoids the problems associated with fusion, as well as the now well-understood complications of...

Outcome study

A total of 21 MP joint arthroplasties in 19 patients were performed for OA over the past 3 years at the authors' institution. Ten of these patients were part of a prospective Food and Drug Administration (FDA)-approved study and the remaining 9 opted out of the study protocol, but were reviewed retrospectively. All patients presenting with OA of the MP joint were requested to participate in the study. All patients completed questionnaires preop-eratively, and at 6 weeks, 12 weeks, 6 months, and...

Dip Fusion Technique

University of Rochester Medical Center, 601 Elmwood Avenue, Box 665, Rochester, NY 14642, USA Arthrodesis of the distal interphalangeal (DIP) joint is a common procedure to treat the painful, unstable distal joint in the osteoarthritic and rheumatoid patient. Less common indications include chronic mallet deformity, missed flexor digitorum profundus avulsions, and distal middle phalangeal fracture nonunion. In most cases, successful fusion improves digital function. Morbidity to the extent that...

Abductor pollicis longus suspensionplasty surgical technique

Fcr Tendon And Trapezium

A 6-cm curvilinear incision is made from 2 finger breadths proximal to the radial styloid process, to 1 cm distal to the base of the meta-carpal (Fig. 2A). The radial artery is exposed and retracted, as are branches of the radial sensory nerve. The first extensor compartment retinacu-lum is released, as would be performed for De-Quervain's disease, leaving the volar attachment intact. At the myotendinous junction of the APL, the ulnarmost slip of APL is released, and freed to the level of its...

Technique of proximal interphalangeal joint arthroplasty

Different surgical approaches have been used for the various PIPJ prosthetic devices, including dorsal, lateral, and palmar approaches 8 . Because important structures must be negotiated with all these approaches, postoperative difficulties may occur. With the dorsal approach, the central slip is vulnerable and with the lateral approach, the collateral ligaments are at risk. The volar plate and the flexor tendon sheath are at risk with the volar or anterior approach. Linscheid and Fig. 4. The...

Treatment of degenerative arthrosis

Reduccion Con Agujas Ksler

Degenerative changes, not related to fracture or dislocation, typically affect the second and third CMC joints, and result in dorsal hypertro-phic osteophyte formation. Patients present complaining of a tender prominence over the interval between the two joints. The pain may result strictly from direct pressure or may be related to use and overuse of the digits, sometimes associated with extensor tendon subluxation over the dorsal prominence (Fig. 7). The prominence is firm and nonmobile,...

Radiofrequency effects on collagen

Orthopedic surgeons have benefited from the use of radiofrequency in a variety of procedures during the past decade. It is only now that we are realizing that there may be some detrimental effects, and it is important to look at this technology more critically. Nevertheless, as with any new technique, judicious use of this technology may allow for stabilization of the joint capsule in a variety of clinical scenarios. Shoulder instability has been treated by a variety of authors using...

Indications

Laxity of the CMC joint of the thumb may be a manifestation of generalized ligament laxity, result as the sequela of trauma, or be a manifestation of metabolic disease such as Ehlers-Danlos syndrome. It is seen most commonly as one manifestation of generalized ligament laxity, particularly in young women in the third to fourth decades of life. They typically also have hyperextension of the elbows, knees, and finger metacar-pophalangeal MP joints. The symptoms are exacerbated by activity, but...

Forearm Incision

The basal joint of the thumb is exposed through a modified Wagner incision. There is a longitudinal component parallel to the long axis of the thumb metacarpal located in the interval between the glabrous palmar and nonglabrous dorsal skin. The incision is continued transversely in the wrist crease to just ulnar to the FCR tendon Fig. 1 . There is invariably a branch of the dorsal sensory branch of the radial nerve crossing the operative field that should be mobilized and protected throughout...
