The clinical and functional results of 46 patients who underwent zone II flexor tendon repair using the Lim/Tsai technique combined with the Kleinert/Duran early active mobilisation regime and place and hold exercises were assessed. The results were compared with 25 patients who were treated by the modified Kessler technique and the Kleinert/Duran regime alone. After a follow-up of 8 to 17 weeks, the Lim/Tsai group had a better grip strength and a significantly better total active motion of 141 degrees compared with 123 degrees . The rupture rates (Lim/Tsai: 1/51; Kessler: 3/26) and the extension deficits were not statistically different in the two groups. However, the complication rate was significantly lower and the average time of treatment was significantly shorter in the Lim/Tsai group. These results support the use of the Lim/Tsai six-strand repair technique in zone II flexor tendon injuries and early active mobilisation without rubber-band traction.

Rotation, angulation, deviation, shortening or a combination of deformities can occur due to phalangeal malunion and can lead to impairment of hand function. A historical cohort study of 57 patients who had phalangeal corrective osteotomies for posttraumatic malunion between 1978 and 1990 was undertaken. 59 rotational, radial/ulnar deviation, flexion/extension, length adjustment procedures, and combinations thereof were performed, using rigid internal fixation. Concurrent tenocapsulolysis was done in 50% of the cases. Satisfactory correction was obtained in 76% of the patients. Bony union was obtained in all cases. A net gain in active range of motion was achieved in 89% of the patients. Excellent and good results were obtained in 96% of the patients who had corrective osteotomies for malunion involving only the bone and in 64% of the patients who had corrections for malunion with involvement of multiple structures (P < 0.01).

Early stage 3 Kienböck's disease has been treated by inner débridement, recontouring, height reconstruction, bone grafting and core revascularization of the lunate; additional procedures included temporary external fixation of the wrist and/or shortening osteotomy of the radius in selected cases. 26 patients, representing an uninterrupted series of 28 procedures, were followed-up for an average of 6.7 years (range 2.5-9.3 years) with periodic clinical and radiographic evaluations until they reached the final comprehensive assessment that included trispiral tomography and MRI. Every patient was subjectively improved, pleased with the result and able to resume his previous job. Pain intensity, rated on a zero to five scale, improved from 2.5 points pre-operatively to a final score of 0.8 points. Wrist motion gained slightly. Grip strength improved significantly. Lunate reconstruction proved successful in 37% of the cases; in an additional 23%, the disease process was stabilized. Carpal height decreased 4.7%; ulnar translation was not substantially altered. Arthrosis increased postoperatively in 55%, remained unchanged in 36% and progressed in 9%. Overall, 43% good and excellent, 43% fair and 14% poor results were observed.
