ABSTRACT
Objective:To explore the technical points and efficacy of gradual traction-unlocking closed reduction technique (GT-UCRT) for Tile C old pelvic fractures.Methods:From August 2012 to June 2021, 6 patients with Tile C old pelvic fracture were treated and followed up at Department of Orthopedics, The Fourth Medical Center, General Hospital of Chinese PLA. They were 4 males and 2 females with an age of (35.8±10.5) years. By Tile classification: 4 cases of type C1.2, 1 case of type C1.3, and 1 case of type C2; time from injury to surgery: 153.8 (64.3, 204.8) days. The 6 patients were treated with GT-UCRT. The time for gradual traction reduction, operation time, hospital stay, intraoperative blood loss and complications were recorded. The modified Matta score was used to evaluate the reduction quality of pelvic fractures, and the Majeed score was used to evaluate the pelvic function at the last follow-up.Results:The 6 patients were followed up for (40.3±22.9) months (from 12 to 72 months) after surgery. The time for gradual traction reduction was (26.7±4.6) days, operation time (119.2±4.6) minutes, hospital stay (11.5±2.9) days, and intraoperative blood loss (533.3±189.6) mL. By the modified Matta score, the pelvic reduction after surgery was rated as satisfactory in 5 cases and as unsatisfactory in 1 case. The length disparity between both lower limbs in the 6 patients was (6.9±1.6) cm before surgery and (1.0±0.4) cm immediately after surgery, showing a statistically significant difference ( t=11.135, P<0.001). One fracture healed 3 months after surgery and 5 fractures 6 months after surgery. The Majeed pelvic score at the last follow-up was (80.8±9.0) points for the 6 patients, yielding 2 excellent cases, 3 good cases and 1 fair case. Delayed wound healing was reported in 1 patient, calf intermuscular venous thrombosis in 2 cases, and emotional anxiety and sleep disorder in 1 patient. No new lumbosacral plexus injury was found in any patient. Conclusions:In the treatment of Tile C old pelvic fractures, since our self-designed GT-UCRT combines the advantages of Ilizarov technique and unlocking closed reduction technique, it can not only protect the lumbosacral plexus but also obtain satisfactory reduction of the fracture.
ABSTRACT
Objective:To investigate the surgical techniques and clinical efficacy of periacetabular osteotomy through the lateral-rectus approach (LRA) for obsolete acetabular fractures.Methods:The 22 patients with old acetabular fracture were retrospectively analyzed who had been admitted to Department of Traumatic Surgery, The Third Affiliated Hospital to Southern Medical University from June 2012 to June 2019. They were 16 males and 6 females, aged from 22 to 61 years (average, 45.0 years). By the Judet-letournel classification, there were 4 anterior + posterior hemitransverse fractures, 2 T-shaped fractures and 16 both column fractures. The time from injury to surgery was 3 to 12 weeks in 15 cases, 3 to 6 months in 5 cases, 9 months in one case, and 3 years in one case. After the whole acetabulum was exposed outside the peritoneum through LRA in all patients, periacetabular osteotomy was conducted under direct vision, followed by fixation with multiple reconstruction plates or integrated acetabular airfoil anatomical plates after reduction. Recorded were the operation time, intraoperative blood loss, fracture reduction quality, affected hip function and complications in the patients.Results:In this cohort the operation time ranged from 110 to 205 min, averaging 140.5 min; intraoperative blood loss ranged from 500 to 2,100 mL, averaging 1,250.4 mL. According to the Matta X-ray criteria, the postoperative reduction was assessed as excellent in 7 cases, as good in 11 and as poor in 4, yielding an excellent and good rate of 81.8% (18/22). All the 22 patients were followed up for 12 to 36 months (mean, 22.1 months) and achieved fracture union. The one-year follow-up showed that their modified Merle d'Aubigné & Postel scores ranged from 6 to 18 points, averaging 14.6 points and giving 6 excellent, 10 good, 3 fair and 2 poor cases [an excellent and good rate of 72.7% (16/22)]. Osteonecrosis of the femoral head developed in 2 patients one of whom underwent total hip replacement.Conclusions:As LRA can expose the entire hemipelic ring from the medial side of the pelvis, the periacetabular osteotomy can be performed and the fractures of anterior or posterior column and the quadrilateral area can be reduced under direct vision through the medial side of the acetabulum. Moreover, ideal results can be achieved with the use of multiple reconstruction plates or integrated acetabular airfoil anatomical plates.
ABSTRACT
Severe pelvic fractures are often accompanied with injuries to abdominal and pelvic organs and nerves and vessels as well.Timely operations for pelvic fractures may be delayed due to urgent management of serious and life-threatening injuries,rendering the fractures obsolete.Patients with severe obsolete pelvic fracture often sustain severe pain,unstable pelvis,neurovascular injuries and organ dysfunction associated with pelvic malunion and malalignment which can only be treated by surgery.This paper reviews the literature and summarizes clinical manifestations of the fracture,indications for surgery,surgical treatment algorithms and difficulties encountered during operation,with an aim to provide useful information for management of obsolete pelvic fractures.
