RESUMO

Osteoarthritis of the first carpometacarpal joint (CMCJ1) is a common, painful condition with positive radiological findings in up to 32% of people over 50 years of age and up to 91% of people over 80 years of age. Currently, there is insufficient evidence to recommend one surgical treatment option over the others. We conducted a retrospective review of 77 patients treated for CMCJ1 osteoarthritis with plate arthrodesis between 1979 and 1996. The review included physical examination, including range of motion (ROM) of the thumb interphalangeal joint, metacarpophalangeal joint and CMCJ1, pinch grip, key grip and power grip strength, and a questionnaire on subjective outcomes (appearance, dexterity, load bearing, pain, strength, subjective overall result and if patients would choose the procedure again). The complication rate was 26%. However, the general patient satisfaction was high with 88% of patients saying they would choose to have the procedure done again. There was a significant decrease (side-to-side difference) in the ROM for palmar and radial abduction as well as opposition when compared to the opposite hand. Furthermore, there was a significant reduction (side-to-side difference) in pinch, key grip and power grip strength. ROM did not seem to have any influence on pain (and vice versa), load bearing, and the subjective overall result. No gender differences were noted. Despite the high complication rate, CMCJ1 arthrodesis remains a viable option for the treatment of CMCJ1 osteoarthritis in select patients requiring good thumb stability.

RESUMO

OBJECTIVE: Reduction of pain and gain of functionality in symptomatic osteoarthritis of the first carpometacarpal joint. INDICATIONS: Idiopathic, rheumatic, or posttraumatic osteoarthritis of the first carpometacarpal joint. RELATIVE CONTRAINDICATIONS: Poor general condition, poor condition of the hand's soft tissue/skin, chronic regional pain syndrome, current or recent infections of the hand, heavy manual labor (decision on a by-case basis). SURGICAL TECHNIQUE: Supine position, hand pronated or slightly tilted. Upper arm tourniquet (Esmarch's method). Loupe magnification. Incision over the first extensor compartment. Exposure and incision of the thumb's basal joint. Resection of the trapezium. Exposure of the abductor pollicis longus (APL) tendon. Longitudinal split of the tendon harvesting the distally based ulnar part of the tendon. The split APL tendon is wrapped around the flexor carpi radialis (FCR) muscle tendon, suturing it to the tendon and back to itself. The rest of the split APL tendon is placed into the gap between the scaphoid and the first metacarpal bone, which is followed by wound closure. POSTOPERATIVE MANAGEMENT: Plaster cast (thumb abduction splint) for 4 weeks. Stable commercially available wrist brace for at least 2 more weeks. RESULTS: There were no significant differences between the FCR arthroplasty (Epping's method) and the APL arthroplasty (Wulle's technique) regarding pain (visual analog scale), disability/usability (DASH score), or range of motion. Patients who had undergone APL arthroplasty showed significantly better grip and pinch strength. Furthermore, the operating time was significantly shorter and scars were significantly smaller in APL arthroplasty.

RESUMO

INTRODUCTION: Thermal injuries with more than 20% of burned body surface area (BSA) lead to systemic shock with generalised oedema in addition to local tissue destruction. This condition, known as burn injury, is caused by immunmodulative mediators whose individual significance is not known in detail. We present an experimental model where plasma of burned animals (burn plasma) is transmitted to healthy animals, to trigger burn iniury without performing direct burn trauma. MATERIAL AND METHODS: The systemic oedema is measured by extravasation of fluorescent albumin in mesenterial venules of Wistar rats. In addition, leukocyte-endothelial interactions ("leukocyte rolling and sticking") is examined. RESULTS: The systemic capillary leak is induced by both direct thermal trauma as well as by infusion of burn plasma. This is evident even after plasma dilution (1% in Ringer's lactate) of the burn plasma. In addition, topical therapy for burned animals (donors) with cerium nitrate led to a significant reduction of plasma extravasation in receiver animals. In addition, systemic antioxidant therapy with high-dose vitamin C of receiver animals, led to a significant reduction of the capillary leak. Leukocyte-endothelial interactions are not significantly affected in either case. CONCLUSION: In summary, for the first time a reliable model of burn injury has been established, which eliminates mediator-independent effects. In addition, our studies show that antioxidant therapy with high doses of vitamin C and topical treatment with cerium nitrate both reduce the systemic capillary leak in receiver animals. Their positive influence could therefore soon be integrated in clinical treatment algorithms.

RESUMO

OBJECTIVE: Reconstruction of the tip of the thumb using a neurovascular flap. INDICATIONS: Transverse defects of the thumb's tip or large defects of the palmar pulp (max. 2.0-2.5 cm) with exposure of bone and/or tendons. CONTRAINDICATIONS: Extensive crush injury, heavy wound contamination, circulatory disorders, acute infection, very large defects (> 2.0-2.5 cm finger length), circumferential soft tissue defects, and previous defects/operations (relative). SURGICAL TECHNIQUE: Supine position, hand supinated, tourniquet, loupe magnification. Mid-lateral incisions along both sides of the finger running from the defect to the interphalangeal joint (small defect) or proceeding further proximally. Careful elevation of the flap including both neurovascular bundles leaving dorsal branches of the bundles (long fingers only) and the flexor tendon sheath intact. Suture of the flap in either flexion position (i.e., advancement flap) (Moberg) or by creating an island-flap through an additional transverse skin incision along the flap's base (O'Brien). Finally, closure of the defect at the flap's base using a full thickness skin graft, Z plasty, or V-Y plasty. POSTOPERATIVE MANAGEMENT: Plaster cast (finger slightly flexed) for 2 weeks. RESULTS: Reliable method. Good functional results with good sensibility and only minor reduction in range of motion.

RESUMO

Scaphoid malunion and carpal malalignment can result after scaphoid reconstruction, if the two fragments are not properly reduced before fixation. However, currently there is no information about which degree of deformity or malalignment can be tolerated without impairing clinical function. The purpose of this study was to investigate the influence of the scaphoid morphology and carpal alignment on clinical outcomes after scaphoid reconstruction. A total of 65 patients with an average age of 29 years were followed-up after a mean period of 45 months. In all patients, osseous union after a first-time scaphoid reconstruction in the middle third had been confirmed. Scapholunate (SL) and radiolunate (RL) angles were obtained on plain radiographs as were intrascaphoid (ISA) and dorsal cortical (DCA) angles and the height/length (H/L) ratio of the reconstructed scaphoid on computed tomography (CT) scans. These parameters were correlated with clinical outcome measures. RL angles correlated significantly with wrist range of motion, grip strength and pain levels, whilst SL angles, ISA, DCA and H/L ratio failed to show significant correlations. Our data suggest that clinical outcome is correlated with correct restoration of bone morphology and carpal alignment. After reconstruction, the RL angle should not exceed 10°.
