Delayed wound healing particularly in difficult wounds and in elderly with co morbidities is a major concern. It leads to the pain, morbidity, prolonged treatment, and require major reconstructive surgery which imposes enormous social and financial burden. Vacuum-assisted closure (VAC) is an alternative method of wound management, which uses the negative pressure to prepare the wound for spontaneous healing or by lesser reconstructive options. Method of VAC application includes thorough debridement, adequate haemostasis and application of sterile foams dressing. A fenestrated tube is embedded in the foam and wound is sealed with adhesive tape to make it air tight. The fenestrate tube is connected to a vacuum pump with fluid collection container. The machine delivers continuous or intermittent suction, ranging from 50 to 125 mmHg. The VAC dressings are changed on 3rd day. Negative pressure therapy stabilizes the wound environment, reduces wound edema/bacterial load, improves tissue perfusion, and stimulates granulation tissue and angiogenesis. All this improves the possibility of primary closure of wounds and reduce the need for plastic procedures. VAC therapy appears to be a simple and more effective than conventional dressings for the management of difficult wound in terms of reduction in wound volume, depth, treatment duration and cost.

Background: Foot drop defined as a significant weakness of ankle and toe dorsiflexion. It leads to high stepping gait, functional impairment and deformity of the foot. Objective of this study was to assess the functional outcome of tibialis posterior (TP) transfer for patient with foot drop in a single center. Methods: This is a retrospective study included 20 patients operated for foot drop of >1 year duration in the last 5 years. Preoperative assessment of muscles of all the three compartment of leg along with radiological assessment of ankle to rule out tarsal disintegration and ankle instability was done. Postoperatively gait, active dorsi/plantar flexion and the range of movement of the ankle and toes were assessed. Results: Tibialis posterior transfer was performed on 20 patients (16 males and 4 females, mean age 31.4 years). Commonest cause of foot drop was Hansen's disease followed by post traumatic peroneal nerve damage and post injection sciatic neuropathy. At mean follow-up of 2 years, all patients, except one, could walk with heel-toe gait without any orthotic support. There was no pain, ruptures or infections of the transferred tendons. 19 of the 20 operated ankles had mean active dorsiflexion of 7.5 , the active plantar flexion of 36.25 , and the total range of movement 43.75 . The active dorsiflexion of the toes ranged from 5-20 . Conclusion: Dynamic tibialis posterior transfer gives good results in terms of normal gait, high patients' satisfaction with minimal donor site morbidity and low complication rate.

Objective: The transfer of peripheral nerves originating above the level of injured spinal cord into the nerves/roots below the injury is a promising approach. It facilitates the functional recovery in lower extremity, bladder/bowel and sexual function in paraplegics. We assessed anatomical feasibility of transfer of lower intercostal nerves to S2 ventral root in human cadaver for management of neurogenic bladder dysfunction in patients with spinal cord injury. Methods: Study was performed in five formalin fixed cadavers. Cadavers were placed in prone position. A transverse incision was made along 11th ribs on both sides and 10th, 11th Intercostal nerves (ICN) and subcostal nerve were harvested up to maximum possible length. In four cadavers the ventral root of S2 was exposed by endoscope and in one by the standard open laminectomy. Intercostal nerves were brought down to lumbo-sacral region, S2 ventral root was cut cranially and feasibility of intercostal to S2 anastomosis was assessed. Results: The mean length of intercostal nerves was 18.4 cm for the 10th 19.5 cm for the 11th and 22.15 cm for the subcostal nerve. The length of harvested nerve and the nerve length necessary to perform sacral roots neurotization were possible in all cases by only by subcostal nerve while T11 and T10 ICN fall short of the required length. Conclusion: For Spinal cord lesions located at the conus, subcostal nerve could be connected to ventral root of S2 in an attempt to restore bladder function while 10th and 11th ICN had enough length to neurotize lumbar plexus.
