ObjectiveTo compare the effectiveness between modified ilioinguinal approach combined with Kocher-Langenbeck (K-L) approach and Stoppa approach combined with K-L approach for the treatment of complicated acetabular fractures.MethodsBetween May 2011 and May 2016, Sixty-two patients with complicated acetabular fractures were treated with operation via combined anterior and posterior approaches. Thirty-four cases (group A) were treated with modified ilioinguinal approach combined with K-L approach, and 28 cases (group B) were treated with Stoppa approach combined with K-L approach. There was no significant difference in gender, age, injury causes, the type of fracture, time from injury to operation, and associated injury between 2 groups (P>0.05). The operation time, intraoperative blood loss, and hospitalization time were recorded. X-ray film was performed to evaluate the fracture reduction according to the Matta reduction criteria and observe the fracture healing, osteoarthritis, and heterotopic ossification. Clinical results were evaluated according to the grading system of modified d’Aubigne and Postel.ResultsThere was no significant difference in operation time, intraoperative blood loss, and hospitalization time between 2 groups (P>0.05). Postoperative incision fat liquefaction occurred in 2 cases in group A and group B respectively, and deep vein thrombosis of lower extremity occurred in 1 case in group A. No iatrogenic injury was found in 2 groups. Fifty-six patients were followed up after operation. Thirty patients in group A were followed up 12-48 months (mean, 31.8 months). Twenty-six patients in group B were followed up 12-46 months (mean, 30.2 months). At 12 months after operation, according to the grading system of modified d’Aubigne and Postel, the hip function was rated as excellent in 9 cases, good in 16 cases, fair in 3 cases, and poor in 2 cases, with the excellent and good rate of 83.3% in group A; the hip function was rated as excellent in 7 cases, good in 14 cases, fair in 2 cases, and poor in 3 cases, with the excellent and good rate of 80.8% in group B. There was no significant difference in the hip function between 2 groups (Z=0.353, P=0.724). The X-ray films showed that there were 23 cases of anatomical reduction, 6 cases of satisfactory reduction, and 1 case of unsatisfactory reduction in group A, and 20 cases, 5 cases, and 1 case in group B, respectively. There was no significant difference in the results of fracture reduction between 2 groups (Z=0.011, P=0.991). Fracture healing was observed in both groups. There was no significant difference in fracture healing time between 2 groups (t=0.775, P=0.106). During follow-up, 5 cases of osteoarthritis changes, 2 cases of heterotopic ossification, and 2 cases of avascular necrosis of femoral head occurred in group A, and 4 cases, 2 cases, and 1 case in group B, respectively. The difference between 2 groups was not significant (P>0.05).ConclusionAccording to the location and type of fracture, making a choice between the modified anterior approach and Stoppa approach, and then combined with K-L approach for treatment of complicated acetabular fracture, can obtain satisfactory effectiveness.
ObjectiveTo investigate the effectiveness of modified suture technique in the treatment of acute closed Achilles tendon rupture.MethodsBetween December 2013 and December 2016, 29 cases with acute closed Achilles tendon rupture were treated with modified suture technique. There were 23 males and 6 females with an average age of 34 years (range, 22-45 years). All patients were sport injuries. The injury located at left side in 22 cases and right side in 7 cases. American Foot and Ankle Surgery Association (AOFAS) ankle and hind foot function score was 44.6±3.6. According to the Amer-Lindholm criteria, 29 cases were rated as poor. MRI showed the complete rupture of the Achilles tendon.ResultsThe operation time was 35-62 minutes (mean, 46 minutes). The intraoperative blood loss volume was 7-15 mL (mean, 10 mL). The incisions healed by first intention, and no sural nerve injury occured. All patients were followed up 5-38 months (mean, 18.4 months). AOFAS ankle and hind foot function score was 93.1±4.3 at 3 months after operation, showing significant difference when compared with the preoperative value (t=–49.581, P=0.000). According to the Amer-Lindholm criteria, the results were excellent in 24 cases and good in 5 cases, and the excellent and good rate was 100%; there was significant difference between pre- and post-operation (Z=–7.294, P=0.000). MRI showed the continuous and integrity of Achilles tendon. No Achilles tendon rupture recurred during the follow-up period.ConclusionModified suture technique in the treatment of acute closed Achilles tendon rupture owns the advantages of less trauma, lower recurrence rate of rupture, lower risk of the sural nerve injury, and satisfactory function recovery.
