Repair of flexor tendon injuries by four strands cruciate technique versus two strands kessler technique

BackgroundFlexor tendon injuries are commonly encountered and the surgical repair still represents a challenging problem. Many repair techniques are present but there is still no ideal one that achieves the best functional outcome. This study was undertaken to compare four-strand locked cruciate repair technique and modified Kessler technique in forty eight patients by assessing the functional outcome.MethodsForty eight patients (114 digits) with flexor tendon injury were assigned into two groups based on suture repair technique; Group A: 24 cases by Modified Kessler repair (50%). Group B: 24cases by 4-strand cruciate repair (50%). Adults in Both groups were rehabilitated by combined Duran protocol and early active mobilization while no specific rehabilitation program was used for pediatric age group. Follow up was from 6 to 36 months (mean 21.5). Functional outcome was assessed by White criteria to all patients after 6 months.ResultsFunctional outcome was better in 4 strand cruciate repair with excellent result in 66.6%, good in 29.1% and fair in 4.1%, as compared to modified Kessler technique in which excellent results were found in 45.8%, good in 37.5%, fair in 12.5% and poor in 4.1% of cases. A better functional result was achieved in 4 strand cruciate repair especially in zone II, with excellent results in 33.3%, good in 50% and fair in 16.6% of cases, as compared to modified Kessler repair with no excellent results, 33.3% good, 50% fair and 16.6% poor results. In zone III, 4 strand cruciate technique showed a better functional outcome with 77.7% excellent and 22.2% good results, as compared to 55.5% excellent and 44.4% good results found in Modified Kessler repair. Zone V showed almost comparable results between the two types of repairs.ConclusionThe 4-strand cruciate repair technique had better functional outcome compared to modified Kessler repair technique, especially in zone II and III.
