Early active motion versus immobilization after tendon transfer for foot drop deformity: a randomized clinical trial.

BACKGROUND: Immobilization after tendon transfers has been the conventional postoperative management. Several recent studies suggest early mobilization does not increase tendon pullout. QUESTIONS/PURPOSES: To confirm those studies we determined whether when compared with immobilization early active mobilization after a tendon transfer for foot-drop correction would (1) have a similar low rate of tendon insertion pullout, (2) reduce rehabilitation time, and (3) result in similar functional outcomes (active ankle dorsiflexion, plantar flexion, ROM, walking ability, Stanmore score, and resolution of functional problems. METHODS: We randomized 24 patients with surgically corrected foot-drop deformities to postoperative treatment with early mobilization with active motion at 5 days (n = 13) or 4 weeks of immobilization with active motion at 29 days (n = 11). In both groups, the tibialis posterior tendon was transferred to the extensor hallucis longus and extensors digitorum communis for foot-drop correction. Rehabilitation time was defined as the time from surgery until discharge from rehabilitation with independent walking. The minimum followup was 16 months (mean, 19 months; range, 16-38 months) in both groups. RESULTS: We observed no case of tendon pullout in either group. Rehabilitation time in the mobilized group was reduced by an average of 15 days. The various functional outcomes were similar in the two groups. CONCLUSION: In patients with Hansen's disease, an early active mobilization protocol for foot-drop correction has no added risk of tendon pullout and provides similar functional outcomes compared with immobilization. Early mobilization had the advantage of earlier restoration of independent walking. LEVEL OF EVIDENCE: Level I, therapeutic study.

Early postoperative active mobilisation versus immobilisation following tibialis posterior tendon transfer for foot-drop correction in patients with Hansen's disease.

After tibialis posterior tendon transfer surgery for foot-drop correction, the foot is traditionally immobilised for several weeks. To test the feasibility of early mobilisation after this procedure in patients with Hansen's disease, 21 consecutive patients received active mobilisation of the transfer starting on the 5th postoperative day. Transfer insertion strength was enhanced by Pulvertaft weave. The results were compared with a historical cohort of 21 patients receiving 4 weeks of immobilisation. The primary outcomes were active dorsiflexion, active plantar flexion and total active motion at the ankle, tendon-insertion pullout and time until discharge from rehabilitation with independent walking without aid. Assessments at discharge from rehabilitation and the last clinical follow-up at more than 1 year were compared between both groups. The Student's t-test was used to compare data between the groups, and 95% confidence interval of the difference between groups was determined. A p-value of 0.05 was considered statistically significant. The average follow-up was 22 months for both groups. There was no incidence of insertion pullout of the tendon transfer in either group. In addition, there was no difference in active dorsiflexion angle between the groups at discharge (mean difference: 2.2 degrees, p=0.22) and final assessment (mean difference: 2.3 degrees, p=0.42). The plantar flexion angles were similar in both groups at discharge (mean difference: 0.5 degrees, p=0.86) and final assessment (mean difference: 0.5 degrees, p=0.57). In addition, there was no difference in total active motion between the groups at discharge (mean difference: 2 degrees, p=0.54) and final assessment (mean difference: 1 degrees, p=0.49). The patients were discharged from rehabilitation with independent walking at 44.04+/-7.9 days after surgery in the mobilisation group compared to 57.07+/-2.3 days in the immobilisation group. This indicates a significant difference in morbidity (mean difference: 13 days, p<0.001) between the two groups. In summary, this feasibility study indicates that early active mobilisation of tibialis posterior transfer in patients with Hansen's disease is safe and has similar outcomes to immobilisation with a reduced time to independent walking, warranting the design of a controlled clinical trial to further substantiate this.

A randomized clinical trial comparing immediate active motion with immobilization after tendon transfer for claw deformity.

PURPOSE: Immobilization after tendon transfers has been the conventional postoperative management. A recent study indicated beneficial effects of an immediate active motion protocol (IAMP) after tendon transfer for claw deformity correction compared with effects in a historical cohort. In this study, we further tested this hypothesis in a randomized clinical trial comparing the effectiveness of the IAMP with that of conventional immobilization. METHODS: Fifty supple claw hand deformities were randomized postoperatively into 2 equal groups for IAMP and immobilization. Therapy began on the second postoperative day for the IAMP group and on the twenty-second postoperative day for the immobilization group. The primary outcome measures were deformity correction, active range of motion of digits, tendon transfer insertion pullout, and time until discharge from rehabilitation. Secondary outcome measures were swelling, pain, hand strength, and dexterity. Both groups were compared at discharge from rehabilitation and at the last clinical follow-up (at least 1 year postoperatively). RESULTS: Assessments were available for all 50 patients at discharge and for 23 patients in each group at follow-up. The average follow-up was 18 months for the IAMP group and 17 months for the immobilization group. Deformity correction, range of motion, swelling, dexterity, and hand strength were similar for both groups at discharge and a follow-up. There was no evidence of tendon insertion pullout in any patient of either group. Relief of pain was achieved significantly earlier with IAMP. Morbidity was reduced by, on average, 22 days with IAMP. CONCLUSIONS: We found that the immediate active motion protocol is safe and has similar outcomes compared with those of immobilization, with the added advantage of earlier pain relief and quicker restoration of hand function. Immediate motion after tendon transfer can significantly reduce morbidity and speed up the rehabilitation of paralytic limbs, and it may save expense for the patients.
