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.

Immediate postoperative active mobilization versus immobilization following tendon transfer for claw deformity correction in the hand.

PURPOSE: To test the hypothesis that immediate postoperative active mobilization of tendon transfer following claw correction with flexor digitorum superficialis 4-tail pulley insertion will achieve similar outcomes to immobilization in a cast for 3 weeks. METHODS: In a prospective study, 32 hands with complete ulnar nerve paralysis had flexor digitorum superficialis middle finger 4-tail pulley insertions for 4-digit claw deformity correction and mobilization for tendon transfer rehabilitation on the second day after surgery. Surgical technique was modified to increase the strength of transfer slip insertion. Historical records of 32 mobile claw deformities treated prior to the prospective trial in the same institution with a similar procedure and immobilized in a cast for 3 weeks was used for comparison. Outcomes were assessed by (1) the status of tendon transfer attachment to flexor pulley during immediate mobilization to detect tendon transfer insertion pullout; (2) results of the claw correction in open hand position and intrinsic plus position, and range of digit flexion using identical outcome measures (3) morbidity following surgery; and (4) comparing results of immediate mobilization with immobilization. RESULTS: There was no incidence of transfer insertion pullout during immediate postoperative mobilization. There was no clinically relevant difference in results of claw correction of both groups in open hand and intrinsic plus position. Total active motion of digit flexion was considerably better with immediate mobilization at late result. A reduction of morbidity by 21 days and an earlier return to daily living activities were benefits to the patient with immediate postoperative mobilization of tendon transfer for claw correction. CONCLUSIONS: This study supports the hypothesis. Immediate postoperative active mobilization is safe and has similar outcomes of deformity correction compared to immobilization. Immediate mobilization has the added benefits of reduced morbidity and improved total active range of digit flexion compared to immobilization. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

[How does one treat the osteitis and osteoarthritis of the extremities in older leprosy patients using granulated table sugar?]. / Comment guérir les ostéites et ostéo-arthrites des extrémités des anciens malades de la lèpre par le sucre cristallisé alimentaire?

A common problem of osteitis and septic arthritis is the recurrent bone infection after surgical debridement, a problem frequently encountered in patients with sequela leprosy. In these cases the authors propose the use of an ancient method of post surgical wound care based on the treatment with ordinary granulated sugar. The hyperosmolar climate created this way in the wounds inhibits the bacterial growth, enhances bacterial death and therefore permits the growth of granulation tissue in order to recover the debrided nude bones. At ILAD (Leprosy Institute of Dakar), 36 osteitis and septic arthritis were treated and healed during the last 2 years from March 1995 to March 1997 using this technic. All the wounds healed in the mean-time of 44 days. Only two of them needed a second debridement and healed afterwards. Up to now the method using ordinary sugar was applied in the treatment of infected wounds, eschars and postsurgical infections. Our experience shows that it also can be indicated to treat bone infections. This method is easy to apply also under often difficult field conditions and is very cheap.

[Nature and sensitivity of bacteria superinfecting plantar ulcers caused by leprosy at the Marchoux Institute, Bamako, Mali]. / Nature et sensibilité des bactéries surinfectant les maux perforants plantaires d'origine lépreuse à l'Institut Marchoux, Bamako, Mali.

To determine potential usefulness of antimicrobial agents and to guide their prescription in the treatment of leprosy plantar ulcers, we conducted an in vitro study about germs' nature and sensitivity to antibiotics. We took samples of plantar ulcers secretion from 107 patients at Marchoux Institute. 92.5% of those ulcers were infected. These samples revealed 145 strains of micro-organisms among those, Staphylococcus aureus (70 strains) and genus Pseudomonas (41 strains) were the most frequent. These bacteria were resistant to several antibiotics currently used at Marchoux Institute (tetracycline, penicillin, cotrimoxazol and erythromicin). Antibiotics, efficient at 80% on tested strains, were expensive for patients. They cannot be recommended for the treatment of local infections. These results outline that the main treatment in plantar ulcers is based upon antiseptic solutions and keeping feet at rest. Antibiotherapy in case of extension of local infection would be based on the results of a previous study of sensitivity.

Motion of the ankle in a simulated supination-external rotation fracture model.

UNLABELLED: An experimental study was undertaken with use of axially loaded, unconstrained cadaver ankles to determine the motion patterns seen with progressive stages of the supination-external rotation type of fracture. As described by Lauge-Hansen, these fractures were modeled by transection of the anterior aspect of the capsule and the anterior tibiofibular ligament (stage I), followed by oblique fibular osteotomy ending at the level of the ankle joint (stage II), transection of the posterior aspect of the capsule (stage III), and sequential sectioning of the superficial and deep fibers of the deltoid ligament (stage IV). Thirteen specimens were tested on an apparatus that allowed for controlled loading while the ankle was passed through a physiological range of dorsiflexion and plantar flexion. The ankles were unconstrained about the axial (internal and external rotation) and coronal (varus and valgus angulation) axes. Measurements were made throughout the range of motion in these axes in order to define the kinematic behavior. In the intact specimens, maximum plantar flexion was associated with a mean (and standard deviation) of 1.9 +/- 4.12 degrees of internal rotation of the talus and maximum dorsiflexion, with a mean of 7.2 +/- 3.88 degrees of external rotation. Varus angulation increased slightly with plantar flexion compared with the value in dorsiflexion (2.4 +/- 2.40 compared with 0.3 +/- 1.96 degrees). Internal and external rotation was not affected by fibular osteotomy or by transection of the superficial fibers of the deltoid ligament. Transection of the deep fibers of the deltoid ligament caused a significant (p < 0.02) increase in external rotation of the talus at maximum plantar flexion; this was corrected incompletely by insertion of an anatomical fibular plate. With the numbers available for study, we could not show that varus or valgus angulation was significantly affected by any combination of sectioning of the deltoid ligament and fibular osteotomy. These experiments were repeated with the addition of fixation of the subtalar joint with a talocalcaneal screw. With the number of specimens available, we could detect no significant difference, with respect to axial rotation, due to fixation of the subtalar joint. However, along the coronal axis, increased valgus angulation (p < 0.02) was seen during plantar flexion when either the deep or the superficial fibers of the deltoid ligament had been cut. CLINICAL SIGNIFICANCE: These results indicate that stability of the loaded ankle is primarily due to the deltoid ligament, which exerts a restraining influence on external rotation of the talus. Complete fibular osteotomy did not cause abnormal motion of the ankle in the absence of a medial injury. In the presence of a complete injury, lateral reconstruction only partially restored the mechanical integrity of the ankle. The results provide justification for the non-operative treatment of isolated fractures of the lateral malleolus. The data also suggest that a lateral fracture associated with a major injury of the deltoid ligament should be treated with anatomical lateral fixation followed by immobilization without early motion, to allow adequate healing of the deltoid ligament at its resting length.

The use of topical phenytoin as an adjunct to immobilization in the treatment of trophic leprosy ulcers.

A total of 30 leprosy patients (controls n = 16; topical phenytoin n = 14) with trophic ulcers on the feet were investigated to ascertain the efficacy of topical phenytoin powder in the healing of ulcers. The ulcers in the two groups were matched for initial size. Healing patterns were assessed by determining changes in depth and planar (surface) dimensions at weekly intervals over a three week study period. Results indicate that while immobilization of the ulcer site is effective in promoting ulcer healing, additional use of topical phenytoin accelerates the healing process. There may however be non-responders to topical phenytoin.
