ABSTRACT

Objective:To investigate the advantages and disadvantages of percutaneous compression plate (PCCP) for femoral neck fractures in the elderly patients.Methods:A retrospective study was conducted of the 31 elderly patients with femoral neck fracture who had been treated with PCCP from January 2012 to December 2018 at Orthopaedic Department, The First People's Hospital of Yancheng, Orthopaedic Department, The Ninth People's Hospital of Wuxi and Department of Orthopaedics, The People's Hospital of Wuxi. They were 16 men and 15 women, aged from 65 to 80 years (average, 70.5 years). By the Garden classification, 7 cases were type Ⅱ, 15 cases type Ⅲ and 9 cases type Ⅳ; by the Singh index, 4 cases were level Ⅲ, 11 cases level Ⅳ, 10 cases level Ⅴ and 6 cases level Ⅵ. The time from injury to operation ranged from 3 to 14 days (average, 5.8 days). The operation time, intraoperative blood loss, fracture reduction, fracture union time, complications and functional recovery of the hip were observed.Results:The operation time averaged 73.4 min and intraoperative blood loss 116.4 mL. At one week after operation, the Garden alignment index was level Ⅰ in 25 cases and level Ⅱ in 6. Superficial incision infection was noted in one case intraoperatively. Follow-ups for the 31 patients ranged from 12 to 47 months (mean, 18.9 months). All the fractures united after 4.9 months on average (from 4 to 8 months). Delayed union occurred in 2 cases, neck shortening in 12 cases, and avascular necrosis of femoral head in 3 displaced subcranial fractures 2 of which were high shear ones. The necrosis of femoral head was treated by arthroplasty in 2 and by conservative treatment in one. The Harris hip scores at the last follow-up for the 31 patients averaged 90.9 (from 75 to 100), giving 15 excellent, 12 good and 4 fair cases and an excellent to good rate of 87.1% (27/31).Conclusions:In treatment of femoral neck fractures in the elderly patients, PCCP has advantages of allowing early weight-bearing after operation, a high rate of fracture union, limited complications and quick and fine functional recovery of the hip. However, it should be used with caution in patients with severe osteoporosis, displaced subcranial or high shear fracture.

ABSTRACT

Objective:To characterize the radial head fracture combined with capitulum cartilage injury (CCI).Methods:The data of 110 patients were analyzed retrospectively who had been treated for radial head fracture at Department of Orthopaedics, The Ninth People's Hospital of Wuxi from January 2011 to May 2020. They were 62 males and 48 females, aged from 17 to 74 years (average, 44.10 years). According to the finding of intraoperative exploration whether CCI was complicated or not, they were assigned into a CCI group and a CCI-free group. The diagnosis, location, size, type, operation method and postoperative recovery of CCI were observed in CCI group. The 2 groups were compared in terms of preoperative general data, range of forearm motion before and after operation and functional recovery of the limb by Mayo elbow performance score (MEPS).Results:CCI was complicated in 25 cases (type Ⅰ in 7 ones, type Ⅱ in 12 ones and type Ⅲ in 6 ones), involving all Mason types of radial head fracture, and located at the lateral capitellum in 13 cases, at the posterolateral capitellum in 9 cases and at the anterolateral capitellum in 3 cases. CCI was diagnosed before operation in 13 cases by physical examination after local anesthesia and imaging examination with a rate of 48% (12/25) for missed diagnosis. The preoperative flexion and extension (61.8°±13.7°) and rotation (60.0°±24.2°) in CCI group were significantly less than those in CCI-free group (77.7°±23.0° and 79.9°±21.9°) ( P<0.05); the Mason types of radial head fracture in CCI group were significantly more serious than those in CCI-free group ( P<0.05). There was no significant difference between the 2 groups in age, gender, combined injury, treatment of radial head fracture, follow-up time, range of forearm motion at the last follow-up or MEPS score ( P>0.05). Conclusions:CCI was complicated in 22.73%(25/110) of the radial head fractures in this cohort and found in all Mason types of radial head fracture, and mostly located at the lateral and posterolateral capitellum. CCI is likely to be missed by imaging examination. In patients with mild radial head fracture and suspected CCI, positive physical examination after local anesthesia is valuable for diagnosis of CCI complication and operative indication. Care should be taken to detect CCI complication by intraoperative exploration in surgery of radial head fracture.

ABSTRACT

BACKGROUND: Lateral locking plate is a classical fixation method to treat lower and distal femoral fractures. However,the incidences of delayed healing, nonunion, plate extubation, and internal fixation rupture exceed 20% after internal fixation.OBJECTIVE: To compare the effectiveness of augmentation plating and single plating for distal and lower femoral fractures with medial comminution.METHODS: Totally 60 patients of lower and distal femoral fractures with medial comminution treated with open reduction and plate fixation were divided into augmentation plating (treatment group, 28 cases) and single lateral plating (control group, 32 cases). We observed the operation time and blood loss, recorded the out-off-bed rehabilitation time, full weight bearing time and complication. The functionary recovery of knee joint was evaluated according to Schatzker-Lambert method for distal femoral fractures in final follow-up.RESULTS AND CONCLUSION: (1) All patients were followed for at least 12 months. All incisions were healed by first intention. (2) The operation time and blood loss in the treatment group were greater than those in the control group (P <0.05). (3) The healing time (3.11±0.31 months), out-off-bed rehabilitation time (4.36±0.91 weeks), full weight bearing time (3.67±0.62 months), complication (0) and excellent and good rate of knee functionary recovery (100%) in the treatment group were better than those in the control group [(5.65±2.33), (7.25±1.02), (6.03±2.61) months, 8, 65.6%] (P < 0.05). (4)Although augmentation plating for treatment of lower and distal femoral fractures with medial comminution prolongs operation time and increases surgical blood loss, the results including the healing rate, complication and satisfaction rate are superior to those treated with single lateral plating.

ABSTRACT

Objective To investigate the principles and effects of cancellous bone wrapping grafting for treatment of segmental defects of long bone.Methods From January 2008 to December 2015,50 patients with segmental long bone defect were treated by various wrapping grafting with rich autogenous cancellous bone.They were 31 males and 19 females,aged from 13 to 69 years (average,34.6 years).The cancellous bone was wrapped by titanium mesh in 8 cases,by wire mesh in 10,by line binding in 13,and by induced membrane in 19.The bone defect was located at tibia in 22 cases,at radius in 10,at humerus in 8,at ulna in 7 and at femur in 3.The length of bone defect ranged from 3 to 9 cm,averaging 5.9 em.Bone healing,complications and functionary recovery of adjacent joint were recorded.The bone defect healing and functionary recovery of adjacent joint were evaluated according to the Paley criteria.Results The incisions healed by the first intention in 48 cases and by the second in 2.All were followed up for 12 to 48 months (average,19.1 months).All the bone defects healed by the first intention but one treated by induced membrane wrapping which was healed 15 months later by the secondary grafting due to nonunion at ends.The total clinical healing time ranged from 3 to 16 months (average,6.1 months).The last follow-ups showed that all the affected limbs resumed weight-bearing activities.The healing of bone defects was graded as excellent in all but one in the group of induced membrane wrapping.Totally,the functionary recovery of adjacent joint was excellent in 18,good in 22,fair in 7 and poor in 3 cases (an excellent and good rate of 80.0%).Conclusions Cancellous bone wrapping grafting can avoid or significantly reduce loosening and absorption of cancellous bone graft after traditional bone grafting.Although it is effective for treatment of large segmental bone defect,its methods should vary according to the specific conditions of the patient.

ABSTRACT

Objective To investigate the augmentation plating for femoral fractures and postoperative femoral nonunion. Methods A retrospective analysis was conducted of 60 patients with femoral fracture or postoperative femoral nonunion who had been treated with augmentation plating from January 2008 to July 2015. They were 36 males and 24 females, aged from 15 to 79 years ( average, 43. 4 years ) . Of them, 20 cases suffered nonunion following intramedullary nailing of femoral shaft fracture, 18 nonunion following lateral plating for femoral distal or lower fracture, and 22 femoral distal or lower fracture complicated with comminuted fracture of medial column. An incision ranging from 6 to 10 cm was made around the fracture ends for augmentative plating for all the patients. Autogenous iliac bone graft was performed in patients with atrophic nonunion or ob-vious gap after reduction of the comminuted fracture. Operation time, intraoperative bleeding, healing time, complications, and functionary recovery of the affected knee were recorded. Results The operation time averaged 121. 5 min and the intraoperative bleeding 356. 3 mL. All the patients were followed up for 12 to 36 months ( average, 16. 9 months ) . All the fractures and nonunions healed after an average time of 4. 2 months ( from 3 to 4 months ) . The time for initial partial weight-bearing averaged 4. 5 weeks ( from 2 to 6 weeks ) and the time for initial full weight bearing 3. 3 months ( from 2 to 4 months ) . Evaluation according to the Karlstrom and Olerud criteria at the last follow-up revealed 29 excellent, 24 good and 7 fair cases, yielding an excellent and good rate of 88. 3%. No infection, loosening, bending or breaking of internal implants, or refracture was noted during follow-ups. Conclusion Augmentation plating through a small incision can lead to fine outcomes for femoral fractures and postoperative femoral nonunion, because it makes up the deficient stability of original in-ternal fixation, reduces the dislocated bone blocks and provides bone grafting to improve defective local bone structure and defective osteogenesis.

ABSTRACT

Objective To explore the therapeutic efficacy of arthroscopy-assisted minimally invasive treatment for posterior tibial plateau fractures.Methods From July 2010 to June 2014,10 posterior tibial plateau fractures were treated at our department by arthroscopy-assisted minimally invasive treatment with percutaneous lag screws.They were 8 men and 2 women,with a median age of 31 years (from 18 to 52 years).All the fractures were closed and fresh,including 3 posteromedial tibial plateau ones,5 posterolateral tibial plateau ones,and 2 posteromedial and posterolateral tibial plateau ones.They were followed up periodically by radiological examinations.At the final follow-up,their knee functions were evaluated by Rasmussen scoring system,and their pain was evaluated by the visual analogue scale(VAS).Subjective factors included swelling,stairs climbing,joint stability,job participation and satisfaction with recovery.Results The follow-ups averaged 18 months (from 12 to 24 months).All fractures healed within 3 months postoperatively,with no infection or serious complications like implant failure.At 12 months postoperation,the mean Rasmussen score was 26 points (from 19 to 30 points).Eight cases were rated as excellent,one as good,and one as fair.Their mean VAS score was 1.2 points (from 0 to 4 points).Conclusion Arthroscopy-assisted minimally invasive management of posterior tibial plateau fractures with cannulated screw fixation is feasible,because it results in limited invasion,satisfactory reduction,reliable fixation,quick functional recovery and a low rate of complications.
