Digital coverage with flaps from the same or neighboring digits.

OBJECTIVE: Several flaps can be dissected from the same or neighboring digits for the reconstruction of relatively large soft tissue digital defects. MATERIAL AND METHODS: In a 6-year period, 106 large soft tissue digital defects were reconstructed with the use of flaps in 101 patients. For the reconstruction of 75 fingertip defects 73 neurovascular, island or advancement flaps (42 homodigital, 18 heterodigital, 13 advancement) and 2 thenar flaps were used. The 31 defects of the proximal and middle phalanges were reconstructed with 3 intermetacarpal and 28 cross-finger flaps (17 de-epithelialized and 11 classic for dorsal and palmar defects respectively). RESULTS: All flaps survived. Subjectively, the results were rated as good or excellent in 69 of 73 distal defects reconstructed with neurovascular island or advancement flaps and in 29 of 31 proximal defects treated with cross-finger and intermetacarpal flaps. The mean DASH score was 4.1 and 3.34 for the neurovascular island/advancement flaps and the cross-finger flaps respectively. CONCLUSIONS: This study elucidates the indications and presents the advantages and disadvantages of flaps used for reconstruction of proximal and distal digital defects. Good results can be obtained with appropriate flap selection and meticulous surgical technique.

Treatment of intra-articular fractures of the distal radius: fluoroscopic or arthroscopic reduction?

In a randomised prospective study, 20 patients with intra-articular fractures of the distal radius underwent arthroscopically- and fluoroscopically-assisted reduction and external fixation plus percutaneous pinning. Another group of 20 patients with the same fracture characteristics underwent fluoroscopically-assisted reduction alone and external fixation plus percutaneous pinning. The patients were evaluated clinically and radiologically at follow-up of 24 months. The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and modified Mayo wrist score were used at 3, 9, 12 and 24 months postoperatively. In the arthroscopically- and fluoroscopically-assisted group, triangular fibrocartilage complex tears were found in 12 patients (60%), complete or incomplete scapholunate ligament tears in nine (45%), and lunotriquetral ligament tears in four (20%). They were treated either arthroscopically or by open operation. Patients who underwent arthroscopically- and fluoroscopically-assisted treatment had significantly better supination, extension and flexion at all time points than those who had fluoroscopically-assisted surgery. The mean DASH scores were similar for both groups at 24 months, whereas the difference in the mean modified Mayo wrist scores remained statistically significant. Although the groups are small, it is clear that the addition of arthroscopy to the fluoroscopically-assisted treatment of intra-articular distal radius fractures improves the outcome. Better treatment of associated intra-articular injuries might also have been a reason for the improved outcome.
