Treatment of Al-Qattan Ⅴb type avulsion injury of flexor digitorum profundus tendon insertion with bone tension-reducing suture and Kirschner wire fixation
Objective To explore the clinical efficacy of bone tension-reducing suture of tendon insertion and Kirschner wire fixation in the treatment of Al-Qattan Ⅴb type avulsion injury of flexor digitorum profundus tendon insertion.Methods From May 2015 to December 2022,8 patients with a Al-Qattan Ⅴb type avulsion injury of flexor digitorum profundus tendon insertion were treated by bone tension-reducing suture of tendon insertion and Kirschner wire fixation.The clinical efficacy was followed up after surgery.Results All 8 patients were follow-up for 12 to 14 months with an average of 12.8 months.There were no postoperative complications such as reduced tension suture breakage and failure,Kirschner wire breakage and loosening,needle infection,incision skin margin and nail bed compression necrosis,deck deformity,and severe finger dysfunction.After surgery,according to the X-ray findings,all fractures healed and the joint space was normal.The fracture healing time was 8 to 10 weeks,with an average of 8.6 weeks.At the last follow-up,there was no significant pain in the distal interphalangeal joint of the affected finger,and the visual analog score(VAS)for pain was(1.0±1.3)points.The total active movement(TAM)system evaluation method was used for functional assessment.The result was excellent in 7 cases and good in 1 case.Conclusion The application of bone tension-reducing suture of tendon insertion and Kirschner wire fixation in the treatment of Al-Qattan Ⅴb type avulsion injury of flexor digitorum profundus tendon insertion is effective,reliable,with fewer complications and significant therapeutic effect.
