Repair of muscle and musculotendinous junction injuries with an autogenous fascial patch

We have used an autogenous fascia lata patch to repair muscle and musculotendinous junction injuries affecting 99 individual muscles in 23 patients with multiple incised wounds to the upper limbs. All patients were followed up for at least 2 years. Two patients with severe dystrophic changes following nerve injuries were excluded from the final analysis. Satisfactory grip strength was restored 6 months following the repair in 19 of the 21 patients we evaluated. Complete active and passive range of wrist and digital motion was seen in 18 of these 21 patients. Tightness of the flexor pollicis longus was seen in 2 patients, one of whom had a deformity of the interphalangeal joint of the thumb that was passively stretched and subsequently reduced. Scar adhesions were noted in 4 other patients, but this did not affect wrist or finger motion, except in one. The autogenous fascial patch repair technique provides strong and good apposition of muscle fibres simply by distributing the force and tension over a large area of the muscle, thereby allowing early mobilization and functional restoration of the extremity.
