Abstract
Conventional surgical treatment of relapsed or neglected club foot deformities is not always successful or easy to apply. The presence of shortened neurovascular structures and unhealthy skin may preclude the surgical interference. Bone resection in severe deformities results in short foot which is not satisfactory functionally and cosmetically.
Objectives
In this study we evaluate the use of the bloodless technique for management of relapsed or neglected club foot deformities.
Methods
From Jan 2000–2006, 64 cases older than 2 years with relapsed or neglected club foot deformities were referred to our center. Four cases were excluded because of inadequate follow up data. This thesis based on 60 consecutive cases (67 feet). The patients average age was 8 years and 4 months (range, 2–16 years). Seven cases were bilateral, 20 Left sides, and 34 Right sides. There were 57 relapsed club foot (5 bilateral), and 3 cases were neglected (2 bilateral). Patients with relapsed club foot had average 3 previous operations (range, 1–8 operations).
There was no preoperative assembling of the apparatus. The construct was designed according to the condition of deformity: equinus, varus forefoot etc. Additional procedures, elongation of tendoachilis was done concomitantly with the original procedure in 10 cases. The patients were discharged from the hospital the same day of the operation
Results
The range of operative time was 1–3 hours with an average of 1.5 hours. Average time in the fixator was 19.6 weeks (range, 10 weeks–38 weeks). After fixator removal cast was applied for 2 months, followed by night splint and special shoes for their daily activities. The average follow-up period was 30.6 months (range, 12–84 months) after fixator removal. The results were good in 55 feet, fair in 9, bad in 3.
Complications
All cases suffered from some sort of pin tract inflammation. For 8 cases: one of the wires had to be removed without anaesthesia due to persistent infection. For 3 cases: replacement of wires under general anaesthesia was performed. Oedema developed in the leg and dorsum of the foot or the ankle in 34cases. Frame adjustment under general anaesthesia in 3 cases. There are others such as: migration of the calcanean wire, 2 cases; over correction with valgus heel, two cases; flatfoot, 4 cases; talar subluxationin, 2 cases; talonavicular subluxation, one case; first metatarsophalangeal subluxation, 2 cases; flat topped talus, one case; broken wire, 2 cases and recurrence in 2 cases.
Discussion
It seems logic that osteotomy of the tarsus must be carried out whenever skeletal growth of the foot is at such an advanced stage that correction can not be established by means of articular repositioning and remodeling. However, equinovarus deformity of the foot in 65 adults (38 feet) was treated by external fixator without open procedure (Oganesyan et al, 1996). After an average follow-up 10 years, satisfactory results were obtained in all feet except four.
Conclusion
Ilizarov Treatment is lengthy, difficult, fraught with complications, and a technically demanding procedure. However, the complications did not affect the final outcome too much. Ilizarov method also offers the advantage of performing many additional procedures for other associated lower limb deformity. We believe that the bloodless technique using Ilizarov external fixator is an effective method in treating relapsed or neglected club foot deformities.
