OBJECTIVE: To explore the effectiveness of arthroscopic treatment of scaphoid fracture nonunion with bone graft and Kirschner wire combined with screw fixation. METHODS: The clinical data of 14 patients with scaphoid fracture nonunion who met the selection criteria between February 2021 and September 2022 were retrospectively analyzed. There were 13 males and 1 female with an average age of 32 years ranging from 17 to 54 years. The time from injury to operation ranged from 6 to 15 months, with an average of 9.6 months. According to the Slade-Geissler classification of scaphoid fracture nonunion, there were 3 cases of grade Ⅲ, 8 cases of grade Ⅳ, and 3 cases of grade Ⅴ. The preoperative visual analogue scale (VAS) score was 5.9±1.0, and the modified Mayo wrist score was 53.2±9.1. There were 2 cases of scaphoid nonunion advanced collapse, both of which were stage Ⅰ. All patients were treated with arthroscopic bone graft and Kirschner wire combined with screw fixation, and the fracture healing was observed by X-ray film monthly after operation, and the effectiveness was evaluated by VAS score and modified Mayo wrist score before and after operation. RESULTS: All patients were followed up 6-14 months, with an average of 8.4 months. All fractures healed in 4-8 months, with an average of 6.3 months. The postoperative pain symptoms and wrist function of the patients significantly improved when compared with those before operation, and the VAS score at last follow-up was 2.4±1.3, and the modified Mayo wrist score was 87.1±6.7, which were significantly different from those before operation ( t=12.851, P<0.001; t=-14.410, P<0.001). According to the modified Mayo wrist evaluation, 9 cases were excellent, 3 cases were good, and 2 cases were fair. CONCLUSION Arthroscopic bone graft and Kirschner wire combined with screw fixation is an effective surgical method for the treatment of scaphoid fracture nonunion.

OBJECTIVE: To explore clinical effect of attaching locking plate with bone grafting based on retaining the original intramedullary nail in treating non-union after intramedullary nail fixation of long shaft fractures of lower limbs. METHODS: A retrospective study was conducted on 20 patients treated with non-union fractures after intramedullary nailing of long shaft fractures of lower limbs from June 2015 to June 2020. All patients were treated with the original intramedullary nailing and bone grafting from the iliac bone, and were underwent open reduction plate internal fixation and bone grafting for old fractures. Among them, 14 were males and 6 were females, aged from 35 to 56 years old with an average of (42.2±9.6) years old. Nine patients were femoral shaft fracture and 11 patients were tibial shaft fracture. According to characteristics of fracture end nonunion, 6 patients were stable/atrophic, 9 patients were unstable/large, and 5 patients were unstable/atrophic. The nonunion time ranged from 8 to 12 months with an average of(9.8±2.0) months after the initial surgery. Visual analogue scale (VAS), knee range of motion, bone healing time, complications and fracture-end healing were recorded before and at the latest follow-up. RESULTS: All patients were followed up for 18 to 48 months with an average of (36.3±10.5) months. The incision of all patients were healed at stageⅠwithout complications such as infection or internal fixation ruptur. Healing time of femur and tibia was (8.5±2.6) months and (9.5±2.2) months. Knee joint motion increased from preoperative (101.05±8.98) ° to postoperative (139.35±8.78) ° at the latest follow-up (t=-12.845, P<0.001). VAS decreased from preoperative (5.15±1.72) to postoperative (0.75±0.96) at the latest follow-up (t=11.186, P<0.001). CONCLUSION On the basis of retaining the original intramedullary nail, the addition of locking plate internal fixation and autogenous iliac bone grafting have advantages of simple operation, less trauma, fewer complications and high fracture healing rate. It is one of the effective surgical schemes for the treatment of nonunion after intramedullary nail fixation of long bone fracture of lower extremity.

Objective: To explore the long-term effect of combined surgery for the treatment of congenital tibial pseudarthrosis in children. Methods: The clinical data of 44 children with congenital tibial pseudarthrosis who underwent combined surgery (tibial pseudarthrosis tissue resection, intramedullary rod fixation, Ilizarov external fixator fixation, wrapped autologous iliac bone graft) from August 2007 to October 2011 at the Department of Pediatric Orthopedics, Hunan Children's Hospital were collected retrospectively. There were 33 males and 11 females. The age at the time of surgery was (3.7±2.2)years (range:0.6 to 12.4 years), including 25 cases under 3 years old and 19 cases above 3 years old.Among them, 37 cases were complicated with neurofibromatosis type 1.The operation status, postoperative complications and follow-up results were recorded. Results: The follow-up time after surgery was (10.9±0.7)years (range:10 to 11 years).Thirty-nine out of 44 patients (88.6%) achieved initial healing of tibial pseudarthrosis, with an average healing time of (4.3±1.1)months (range:3 to 10months).In the last follow-up, 36 cases (81.8%) had unequal tibial length, 20 cases (45.4%) had refractures, 18 cases (40.9%) had ankle valgus, 9 cases (20.4%) had proximal tibial valgus, and 11 cases (25.0%) had high arched feet.Nine cases (20.4%) developed distal tibial epiphyseal plate bridging.17 cases (38.6%) had abnormal tibial mechanical axis.Seven cases (15.9%) developed needle infection, and one case (2.3%) developed tibial osteomyelitis. 21 patients (47.7%) had excessive growth of the affected femur.Five patients (11.3%) had ankle stiffness, and 34 patients (77.2%) had intramedullary rod displacement that was not in the center of the tibial medullary cavity.Among them, 8 cases (18.1%) protruded the tibial bone cortex and underwent intramedullary rod removal.18 children have reached skeletal maturity, while 26 children have not been followed up until skeletal maturity. Conclusion: Combined surgery for the treatment of congenital pseudarthrosis of the tibia in children has a high initial healing rate, but complications such as unequal tibia length, refracture, and ankle valgus occur during long-term follow-up, requiring multiple surgical treatments.

OBJECTIVE: To investigate the clinical effect of double plate combined with iliac bone graft in the treatment of femoral nonunion after intramedullary nailing. METHODS: From December 2008 to December 2017, double plate combined with autogenous iliac bone graft was used to treat femoral nonunion after intramedullary nailing. There were 11 cases, including 10 males and 1 female, aged 35 to 62 years, and the time from fracture to nonunion was 12 to 20 months. According to Judet classification, there were 8 cases of atrophic nonunion and 3 cases of proliferative nonunion. Regular follow-up was conducted after operation to record the fracture healing time, load-bearing activity time and complications, and to observe the repair effect of double plate fixation combined with iliac bone graft on nonunion after femoral shaft fracture operation. RESULTS: All patients were followed up for 12 to 22 months. The operation time was 70 to 130 min and the blood loss was 180 to 350 ml. After operation, 2 cases had knee stiffness, which recovered after passive exercise with CPM machine for 2 weeks;1 case had pain in iliac bone donor area, which was relieved after 3 months. The time of fracture healing was 24 to 40 weeks, and the time of complete weight-bearing activity was 14 to 32 weeks. SF-36 quality of life score at the final follow-up:body pain 70 to 82, activty 70 to 82, social function 72 to 83, the overall health 72 to 82. At the end of the follow-up, there were no complications such as limb shortening, infection, poor wound healing, internal fixation failure (fracture, loosening). CONCLUSION It is an effective method to treat nonunion of femur after intramedullary nailing by using double plate combined with autogenous iliac bone graft.

OBJECTIVE: To investigate the methods and clinical effects of autologous iliac bone transplantation, platelet-enriched plasma(PRP) and extracorporeal shock wave(ESW) in the treatment of nonunion. METHODS: From January 2015 to December 2016, 60 patients with nonunion were treated, including 41 males and 19 females, aged 18 to 42 years old with an average age of 29 years old. Patients with nonunion were divided into autologous bone transplantation treatment group(control group), autologous bone transplantation and platelet-rich plasma(PRP) combined with extracorporeal shock wave(ESW) treatment group(experimental group). The callus formation, local complications, final growth of fracture and Johner-Wruhs functional classification of operative limbs of the two groups were compared 3 months after operation. RESULTS: Fifty-five patients were followed up, 27 in the control group and 28 in the experimental group, 5 patients were lost. The follow-up period ranged from 8 to 24 months. The callus score in the control group was significantly lower than that in the experimental group at 3 months after operation(<0.05). There was no swelling and infection in the skin of the iliac bone acquisition site and non-union operation site in both groups. The clinical and bone healing time of the control group was significantly longer than that of the experimental group(<0.05). In the experimental group, 28 patients achieved bone union; in the control group, 24 patients achieved bone union, and 3 patients had bone nonunion again. The excellent and good rate of Johner-Wruhs functional classification of affected limbs in the control group was significantly lower than that in the experimental group(<0.05). CONCLUSIONS Autologous iliac bone transplantation combined with platelet-enriched plasma(PRP) and extracorporeal shock wave(ESW) has a certain effect in the treatment of bone nonunion after fracture surgery. It can significantly improve the formation of new bone. It is a comprehensive and useful way to treat bone nonunion after fracture surgery in clinical work.

STUDY DESIGN: A retrospective cohort study. PURPOSE: To compare the clinical and radiological outcomes of patients who underwent anterior cervical discectomy and fusion (ACDF) supplemented with plate fixation using allograft with those who underwent ACDF using tricortical iliac autograft. OVERVIEW OF LITERATURE: As plate fixation is becoming popular, it is reported that ACDF using allograft may have similar outcomes compared with ACDF using autograft. METHODS: Forty-one patients who underwent ACDF supplemented with plate fixation were included in this study. We evaluated 24 patients who used cortical ring allograft filled with demineralized bone matrix (DBM) (group A) and 17 patients who used tricortical iliac autograft (group B). In radiological evaluations, fusion rate, subsidence of grafted material, cervical lordosis, fused segmental lordosis, and radiological adjacent segment degeneration (ASD) were observed and analyzed with preoperative and postoperative plain radiographs. Clinical outcomes were evaluated using the Neck Disability Index score, Odom criteria, and Visual Analog Scale score of neck and upper extremity pain. Radiological union was determined by dynamic radiographs using cutoff values of 1 mm of interspinous motion as the indication of pseudarthrosis. RESULTS: There was no significant difference in the fusion rate, graft subsidence, cervical lordosis, fused segmental lordosis, and ASD incidence between the groups. Operative time was shorter in group A (136 min) than in group B (141 min), but it was not significant (p>0.05). Blood loss was greater in group B (325 mL) than in group A (210 mL, p=0.013). There was no difference in the clinical outcomes before and after surgery. CONCLUSIONS: In ACDF with plate fixation, cortical ring allograft filled with DBM group showed similar radiological and clinical outcomes compared with those of the autograft group. If the metal plate is reinforced, using cortical ring allograft could be a viable alternative to autograft.

Congenital insensitivity to pain with anhidrosis (CIPA) is a rare disease that affects the sensory and autonomic nervous system. The patients do not have the ability to sense different sensations, such as pain, which tends to lead to different injuries. In addition, the patients suffer from fluctuations in body temperature due to autonomic involvement. The present case was a five-year-old girl with a neglected distal femur fracture. X-rays taken during the follow-up showed marked callus formation and pseudarthrosis of the distal femur. She had biting injuries of the tongue, auto-amputation of the fingers, some developmental delay and a history of recurrent fever with an unknown origin. The electrodiagnostic study was normal. The quantitative sudomotor axon reflex test revealed markedly reduced postganglionic sudomotor axonal responses at all sites recorded on the left. She was diagnosed with CIPA. As the initial presentation of CIPA involves the musculoskeletal system, orthopedic surgeons should have a high index of suspicion.

OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is commonly used surgical procedure for cervical degenerative disease. Among the various intervertebral spacers, the use of allografts is increasing due to its advantages such as no harvest site complications and low rate of subsidence. Although subsidence is a rare complication, graft collapse is often observed in the follow-up period. Graft collapse is defined as a significant graft height loss without subsidence, which can lead to clinical deterioration due to foraminal re-stenosis or segmental kyphosis. However, studies about the collapse of allografts are very limited. In this study, we evaluated risk factors associated with graft collapse.METHODS: We retrospectively reviewed 33 patients who underwent two level ACDF with anterior plating using allogenous bone graft from January 2013 to June 2017. Various factors related to cervical sagittal alignment were measured preoperatively (PRE), postoperatively (POST), and last follow-up. The collapse was defined as the ratio of decrement from POST disc height to follow-up disc height. We also defined significant collapses as disc heights that were decreased by 30% or more after surgery. The intraoperative distraction was defined as the ratio of increment from PRE disc height to POST disc height.RESULTS: The subsidence rate was 4.5% and graft collapse rate was 28.8%. The pseudarthrosis rate was 16.7% and there was no association between pseudarthrosis and graft collapse. Among the collapse-related risk factors, pre-operative segmental angle (p=0.047) and intra-operative distraction (p=0.003) were significantly related to allograft collapse. The cut-off value of intraoperative distraction ≥37.3% was significantly associated with collapse (p=0.009; odds ratio, 4.622; 95% confidence interval, 1.470-14.531). The average time of events were as follows: collapse, 5.8±5.7 months; subsidence, 0.99±0.50 months; and instrument failure, 9.13±0.50 months.CONCLUSION: We experienced a higher frequency rate of collapse than subsidence in ACDF using an allograft. Of the various pre-operative factors, intra-operative distraction was the most predictable factor of the allograft collapse. This was especially true when the intraoperative distraction was more than 37%, in which case the occurrence of graft collapse increased 4.6 times. We also found that instrument failure occurs only after the allograft collapse.
