Clinical TrialMinimally invasive periprosthetic plate osteosynthesis using the locking attachment plate.
Stable fixation of periprosthetic or periimplant fractures with an angular stable plate and early weight bearing as tolerated. ⋯ In 6 patients with periprosthetic fractures and 2 patients with periimplant fractures, no surgical complications (e.g., wound infection or bleeding) were observed. The mean time to bony union was 14 weeks. No implant loosening of the locking attachment plate was observed. At the follow-up examination, all patients had reached their prefracture mobility level.

Clinical Trial[Transfer of the flexor digitorum superficialis tendons of the middle and ring fingers to restore extension of fingers and thumb (Boyes' transfer)].
Restoration of extension in the metacarpophalangeal joints of the fingers as well as in the interphalangeal joint of the thumb by transfer of the superficial flexor tendons of the long and ring fingers (flexor digitorum superficialis III and IV). ⋯ From March 1999 to January 2010 a Boyes' transfer was performed in 13 patients (8 female and 5 male) and the right side was affected in 8, the left side in 5 and the dominant hand in 7 cases. The patient age at the time of surgery was an average of 47 ± 17 (13-73) years. The interval between radial palsy and tendon transfer was an average of 79 ± 144 (4-543) months. The final follow-up was performed at an average of 82 ± 35 (32-165) months. According to the Haas scoring system finger extension was excellent in 5, good in 5, fair in 3 and unfavorable in 4 cases and thumb extension was excellent in 5, good in 3, fair in 1 and unfavorable in 5 patients. The mean disabilities of the arm, shoulder and hand (DASH) score was 36 ± 24 (11-85) points. Although disability of varying degrees persisted in all patients, Boyes' transfer is considered to be a safe procedure to restore finger and thumb extension with excellent and good functional results, a high degree of patient satisfaction and few complications.

Clinical Trial[Restoration of thumb flexion at the interphalangeal joint by transposition of the flexor digitorum superficialis tendon from the ring finger].
Restoration of active thumb flexion at the distal joint. ⋯ In this study 10 patients with FDS IV transposition to reconstruct an isolated rupture of the FPL tendon could be followed for an average of 4.1 years postoperatively. The active range of motion of the IP joint of the thumb averaged 65° (10-100°), 8/10 patients achieved an equal active and passive range of motion of the IP joint of the thumb, in 2 patients some flexion insufficiency remained, 9 patients could reach the fingertip of the small finger with the thumb and 1 patient lacked 3 mm. Contracture of the proximal thumb joint developed in two patients. After removal of the FDS IV tendon two patients developed contracture of the PIP joint of the ring finger. The grip force was reduced to 81 %, lateral grip to 83 % and pinch grip to 77 %. The DASH score averaged 18 (0-31) and 8/10 patients would choose to undergo this surgery again.

Clinical Trial[Operative treatment of claw deformity by lassoplasty].
The aim is correction of claw deformity of the fingers by intrinsic paralysis. ⋯ From April 2003 to June 2012 a total of 17 patients, 8 female and 9 male were surgically treated for claw deformity. The dominant hand was affected in seven patients. The average age was 46 ± 15 (22-80) years, the average interval from onset of ulnar palsy to lassoplasty was 61 ± 91 (3-288) months. The final follow-up was performed after an average of 42 ± 32 (2-112) months. Claw deformity was resolved in 14 out of the 17 patients. The grip strength was on average 58 ± 28 % (11-96 %) of the unaffected hand, the mean disabilities of the arm, shoulder and hand (DASH) score was 32 ± 18 (5-68) points and the degree of patient satisfaction 7 ± 2 (0-10). According to own results and those in the literature lassoplasty can be recommended for the treatment of claw deformity.

Clinical Trial[Abductor digiti minimi muscle flap for defect coverage of the hand].
Defect coverage of the ulnar aspect of the hand, wrist and hypothenar with an abductor digiti minimi muscle flap and split skin graft. ⋯ In total, 9 patients showed good results with a reliable defect coverage due to a constant anatomy and easy preparation.
