Objective To investigate the effectiveness of meshy fascia encapsulating cancellous bone graft in repair of bone defect after limb fractures. Methods A clinical data of 21 cases of traumatic bone defect after limb fractures, who were treated with meshy fascia encapsulating cancellous bone graft between June 2011 and December 2016, was retrospectively analyzed. There were 13 males and 8 females, aged 14-64 years with an average of 40.1 years. The location of bone defect included humerus in 3 cases, radius in 5 cases, ulna in 4 cases, femur in 2 cases, and tibia in 7 cases. AO classification of primary fractures were type A in 2 cases, type B in 7 cases, and type C in 12 cases. There were 14 cases of open fracture, and 7 cases of closed fracture associated with bone defect. The time from injury to bone defect repair was 5-165 days (mean, 21.3 days). The length of bone defect was 2.5-6.5 cm with an average of 4.5 cm. Results The operation time was 86-130 minutes (mean, 101 minutes). The intraoperative blood loss was 185-647 mL (mean, 316 mL). One case of superficial infection and 2 cases of delayed healing of incision occurred after operation, and no neurovascular injury occurred. All the 21 patients were followed up 12-36 months (mean, 19 months). The clinical healing time was 2.5-7.0 months (mean, 5.4 months); no delayed healing and nonunion occurred, the bony healing rate was 100%. There was no deep infection, infection recurrence, broken of internal fixator, or refracture. At last follow-up, the grading of bony healing were all rated as excellent, and the functional recovery of the affected limb was excellent in 12 cases, good in 7 cases, and fair in 2 cases with an excellent and good rate of 90.5%. Conclusion Meshy fascia encapsulating cancellous bone graft in repair of bone defect after limb fracture is characterized by easy to harvest fascia, simplicity of operation, no adverse reaction, lower cost, and satisfactory results.
Objective To explore the clinical characteristics and treatment of “kissing fracture” of humeroradial joint. Methods A clinical data of 12 patients with “kissing fracture” of the humeroradial joint between January 2016 and June 2021 was retrospectively analyzed. There were 8 males and 4 females with an average age of 41.9 years (range, 15-75 years). The fractures caused by falling in 7 cases, by falling from height in 3 cases, and by sports in 2 cases. The time from injury to admission was 2-72 hours (median, 2 hours). According to Mason’s classification, the radial head fractures were rated as type Ⅰ in 2 cases, type Ⅱ in 8 cases, and type Ⅲ in 2 cases. According to Grantham’s classification, the humeral capitulum fractures were rated as type Ⅰ in 10 cases and type Ⅱ in 2 cases. Among them, 4 cases of Grantham type Ⅰ humeral capitulum fracture were missed by X-ray film and confirmed by CT and/or MRI. Four cases were complicated with other injuries of elbow joint. The radial head fractures were fixed with screws or mini plate in 11 cases and treated conservatively in 1 case; the humeral capitulum fractures were fixed with screw or plate in 9 cases, removed in 1 case, and treated conservatively in 2 cases. X-ray film was used to evaluate the fracture healing; Mayo Elbow Performance Score (MEPS) was used to evaluate the functional recovery of the affected limb, and the range of motion (ROM) of the elbow joint of the affected limb was detected. Results All the incisions healed by first intention without early complications. All patients were followed up 10-24 months, with an average of 15.2 months. X-ray films showed that all fractures healed, and the healing time was 2-3 months, with an average of 2.3 months. At last follow-up, the ROM of flexion-extension of the elbow joint was 65°-161°, with an average of 136.9°; the ROM of rotation was 70°-180°, with an average of 149.2°. MEPS ranged from 70 to 100, with an average of 87.4; 8 cases were excellent, 2 cases were good, and 2 cases were fair; the excellent and good rate was 83.3%. Conclusion The “kissing fracture” of the humeroradial joint is relatively rare, and the humeral capitulum fracture is milder than radial head fracture. X-ray examination alone can easily miss the diagnosis of Grantham type Ⅰ humeral capitulum fracture. The “kissing fracture” of the humeroradial joint is treated according to the principle of intra-articular fracture, and the good effectiveness can obtain.
