ObjectiveTo evaluate the effectiveness of internal fixation with headless compression hollow embedding screws in the treatment of intraarticular fracture of elbow.MethodsBetween March 2012 and September 2018, 12 patients with intraarticular fracture of elbow were treated with internal fixation with headless compression hollow embedding screws. There were 7 males and 5 females with an average age of 50.3 years (range, 22-65 years). Cause of injury included falling in 7 cases, falling from high places in 4 cases, and traffic accident in 1 case. Ten patients were distal humerus fractures which were classified as type 13-B3 in 8 cases and type 13-C3 in 2 cases according to the International Association of Internal Fixation Research (AO/ASIF). Two patients were radial head fractures which were classified as type Ⅲ according to the modified Mason classifications. The preoperative visual analogue scale (VAS) score was 8.25±0.83. The time from injury to operation was 3-5 days (mean, 3.7 days).ResultsAll incisions healed by first intention. All 12 patients were followed up 6-15 months, with an average of 8.4 months. The results of X-ray films and CT examination showed that the fracture ends were anatomic reduction, and the fractures healed at 6-11 months after operation, with an average of 7.8 months. One patient had heterotopic ossification at 4 months after operation. The VAS scores were 5.17±0.79 at 2 weeks after operation and 0.50±0.50 at last follow-up. There were significant differences between the time points (P<0.05). At last follow-up, the Mayo elbow function score was 68-95, with an average of 83.9. The activity of elbow joint recovered.ConclusionThe intraarticular fracture of elbow can be firmly fixed by the headless compression hollow embedding screw, which can allow the early functional training of the elbow joint, reduce the incidence of heterotopic ossification, and obtain good effectiveness.
To investigate the operative treatment of displaced intra-articular calcaneal fractures (DIACFs) using a combination of small lateral incision approach and internal fixation and allograft bone transplantation. Methods From January 2005 to December 2007, 28 patients with 34 DIACFs were treated with open reduction, allograft bone transplantationand internal fixation through a small lateral incision approach. Of them, there were 18 males and 10 females, aged 16-65 years. The disease course was 2 hours to 18 days. According to Sanders classification, there were 18 cases of type II fractures, 10 cases of type III fractures and 6 cases of type IV fractures. Results 22 patients with 28 DIACFs were followed up 18.5 months (13-28 months). The wound of 26 feet achieved primary heal ing, the acute rejection was found in 2 patients and developed wound compl ications. Both patients underwent further surgery prior wound heal ing. After the internal fixation were removed, factures was fixed with external fixator, closed continuous irrigation and drainage was employed. In the meantime, both patients received antibiotics and incisional dressing change. As a result, one achieved primary heal ing, the other developed delayed heal ing. Thepreoperative X-ray film showed that Bouml;hler angle was (6.19 ± 9.66)° and Gissane angle was (103.04 ± 15.03)°; the postoperative X-ray film demonstrated that Bouml;hler angle was (34.51 ± 5.89)° and Gissane angle was (112.18 ± 10.50)°; showing statistically significant differences (P lt; 0.05). The internal fixation of 12 patients (14 DIACFs) were removed at 6 -10 months after operation, Bouml;hler angle was (32.81 ± 5.10)° and Gissane angle was (110.81 ± 9.98)°. When compared with preoperative X-ray film, statistically significantdifferences (P lt; 0.05) was found, but there was no statistically significant differences (P gt; 0.05) when compared with normal X-ray film. According to the American Orthopedic Foot and Ankle Society evaluation system for ankle-hind foot, 3 feet scored 60-70 points, 10 feet 70-80 points, 12 feet 80-90 points and 3 feet 90-100 points. Conclusion Allograft bone transplantation is an option for management of DIACFs, because it enables satisfactory reconstruction of bone defects, allows met anatomic reduction and functional recovery, maintaining restoration of calcaneal height and anatomic reduction of the posterior facet.
Objective To assess the treatment effect of intra-articular fracture with absorbable screws and rods.Methods From June 1998 to August 2004， 35 patients with intra-articular fracture were treated by absorbable screws and rods made of self-reinforcedpolyglycolicacid (SR-PGA) and self-reinforcedpoly-L-Lacticacid (SR-PLLA). Of 35 patients, 30 were males and 5 were females (aged from 4 to 62 years). All cases had intra-articular or periarticular fracture. The interval between injury and operation was 3 hours to 29 days. Fracture were fixed with full thread screws of SR-PGA in 9 cases, with tensile screws of SR-PLLA in 26 cases, with rods of SR-PLLA in 15 cases. Bone traction orplaster external fixation were carried out postoperatively. Results The patients were followed from 3 months to 60 months with an average of 28 months．The wounds healed by first intention, and the healing time of bone was 1－3 months. No dislocation, infection and local effusion occurred. Functional recovery was satisfactory．According to AASO articular function standard, the results were excellentin 26 cases, good in 7 cases, fair in 1 case, and poor in 1 case; the total excellent and good rate was 94.3%. Conclusion Internal fixationof absorbable screws and rods are a perfect procedure in treating intraarticular and periarticularfracture, which can avoid the pain of taking out internal fixation materials because of second operation．
Objective To compare the effectiveness of open reduction and internal fixation with plate and closed reduction and internal fixation with Kirschner wire (K-wire) in the treatment of intra-articular displaced calcaneal fractures in older children. MethodsA clinical data of 35 older children (37 feet) with intra-articular displaced calcaneal fractures who were admitted between November 2014 and November 2020 and met the selection criteria were retrospectively analyzed. Among them, 19 cases (20 feet) underwent open reduction and internal fixation with plate (plate group), and 16 cases (17 feet) underwent closed reduction and internal fixation with K-wire (K-wire group). There was no significant difference in gender, age, cause of injury, side and type of fracture, and time from injury to admission, and preoperative calcaneal Gissane angle and Böhler angle (P>0.05). The postoperative calcaneal Gissane angle, Böhler angle, complications, and fracture healing were compared between the two groups. The ankle function was evaluated based on the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring system. Results Incision necrosis occurred in 1 foot in the plate group after operation, which healed after symptomatic treatment; the other incisions in the two groups healed by first intention. All children were followed up 12-39 months (mean, 19 months). X-ray films showed that the fractures in both groups healed; the healing time was (2.65±0.71) months in the plate group and (2.24±1.38) months in the K-wire group respectively, with no significant difference (t=1.161, P=0.253). At last follow-up, the calcaneal Gissane angle and Böhler angle returned to normal; and the difference between pre- and post-operation in the two group was significant (P<0.05), but there was no significant difference between the two groups in the difference between before and after operation (P>0.05). In the plate group, the plate was removed at 11-22 months after operation (mean, 16.8 months). At last follow-up, the AOFAS ankle-hindfoot score in the plate group was 91.2±5.1, which was significantly higher than that in the K-wire group (86.9±6.1) (t=2.316, P=0.027). The ankle function was rated as excellent in 15 feet, good in 4 feet, and fair in 1 foot in the plate group, and excellent in 14 feet and good in 3 feet in the K-wire group, and the difference between the two groups was not significant (Z=1.712, P=0.092). ConclusionFor intra-articular displaced calcaneal fracture in older children, the open reduction and internal fixation with plate and closed reduction and internal fixation with K-wire can achieve good effectiveness, but the former has better recovery of ankle function.
Objective To introduce a clinical treatment for the reconstructionof calcaneal thalamus by bone autograft and subtalar arthrodesis for antiquatedintraarticular calcaneal fractures. Methods From July 2000 to October 2003, 11 cases with antiquated intraarticular calcaneal fractures were treated. Of the 11 cases, 9 were males and 2 females,whose ages ranged from21 to 48 years. All unilateral calcanei were involved in the 11 cases. The modified extended Lshaped approach lateral to calcaneus was adopted. The primary treatment was manipulation and immobilization with the reconstruction of calcaneal thalamus by bone autograft and subtalar arthrodesis. The average volume of the ilium for the autograft was 3.0 cm×2.5 cm×1.8 cm. Protruded osteophyte from the lateral wall of calcaneus were ablated in all 11 cases. Results All the 11 cases were followed up for 3 to 18 months, 11.5 monthson average. The reconstructed calcaneal thalamus was healed 10 to 12 weeks after the operation. Some of the patients could walk with load 8 weeks after the operation, and the average time for all the patients to walk with load was 13.2 weeks. There were 4 cases of excellent result, 5 cases of good result, and 2 cases of fair result, according to ZHANG Tieliang’s foot score system. Plain radiograph showed that Bohler angle, width of calcaneus and height of calcaneal thalamus were nearlyrestored to normal. Conclusion With the improvement of calcaneal abnormality and restoration of the shape and function of hind foot, reconstruction of calcaneal thalamus by bone autograft combined with subtalar arthrodesis is effective in treating antiquated intra-articular calcaneal fractures.
Objective To summarize the preliminary effectiveness of I.T.S. locking plate for intra-articular calcaneal fractures. Methods Between July 2010 and July 2011, 18 cases of intra-articular calcaneal fractures were treated. There were 10 males and 8 females with an average age of 46 years (range, 25-64 years). According to Sanders classification system, there were 3 cases of type II, 9 cases of type III, and 6 cases of type IV. The disease duration was 5-11 days (mean, 6 days). Open reduction and internal fixation with I.T.S. locking plate were performed via an L-shaped lateral extending incision. Results Superficial infection occurred in 1 case, and was cured after dressing changing; healing of incision by first intention was obtained in the other cases. Sixteen cases were followed up 14 months on average (range, 12-18 months). X-ray films demonstrated the bone union in all cases with an average union time of 12 weeks (range, 10-14 weeks). No implant failure or irritation of peroneal tendon occurred during follow-up. X-ray films showed subtalar post-traumatic arthritis with mild pain in 1 case at 11 months after operation, which was relieved by conservative treatment. At last follow-up, the Bouml;hler angle was improved from (12.9 ± 3.2)° preoperatively to (33.8 ± 4.0)° postoperatively, showing significant difference (t=22.78, P=0.00); the Gissane angle was improved from (83.6 ± 6.4)° preoperatively to (119.9 ± 8.5)° postoperatively, showing significant difference (t=17.02, P=0.00). The visual analogue scale (VAS) score was 1.3 ± 1.2, and the ankle and hindfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS) was 80.3 ± 7.9 at last follow-up. Conclusion Treatment of intra-articular calcaneal fracture with I.T.S. locking plate can obtain a stable fixation, which is a safe and effective method.
To compare the effect and syndrome of treating intra-articular calcaneal fractures using Kirschner’s wire or AO calcaneal plate. Methods From March 2003 to March 2006, 71 cases (86 feet) of intra-articular calcaneal fractures were treated with Kirschner’s wire or AO calcaneal plate. Among them, 39 cases (48 feet) were treated using Kirschner’s wire, male 34, female 5. The age ranged from 15 to 64 years old, 36 on average. The course of illness was from 4 hoursto 10 days. There were 9 double side bone fractures and 30 one side bone fractures. Based on Sanders type, Type II were 40 feet, Type III were 7 feet and Type IV was 1 foot. The other 32 cases (38 feet) were treated using AO calcaneal plate, male 30, female 2. The age ranged from 18 to 55 years old, 33 on average. The course of illness was from 4 hours to 10 days. There were 6 double side bone fractures and 26 one side bone fractures. A total of 31 feet belonged to Sanders Type II, 5 to Type III, and 2 to Type IV. The 12-month follow-up, at least, was carried out in order to valuate the patients. The valuating items included: preoperative and postoperative Bohler’s angle and Gissane’s angle; heel bone height and width(contrast with the opposite side); to judge reposition circs by means of the CT scan and Borden’s judgment; function valuation adopting the American Orthopedic Foot amp; Ankle Society (AOFAS) grade point system. Results Patients with Kirschner’s wire fixed were followed up for 12 to 48 months, and AOFAS score ranged from 75 to 100 points, 90.6 on average. The excellent and good rate was 87.8%. The preoperative Bohler’s angle was from 0 to 10°, 7.8° on average, and postoperative from 30 to 40°, 33.2° on average. The preoperation Gissane’s anglewas 75 to 95°, 84° on average; and postoperative from 115 to 135°, 125° on average. There was significant difference (P lt; 0.05). The postoperative compl ications were that 1 foot was the incision edge shallow putrescence and 1 foot was the needle way infection. Patients with AO calcaneal plate fixed were followed up for 12 to 48 months, and AOFAS score was from 49 to 100 points, 87.5 on average. The excellent and good rate was 81.6%.There was no significant difference between the two groups (P gt; 0.05). The preoperative Bohler’s angle ranged from 0 to 15°, 6.5° on average, and postoperative from 25 to 40°, 30.2° on average. The preoperative Gissare’s angle was 72 to 92°, 80° on average; and postoperative from 115 to 130°, 120° on average. There was significant difference (P lt; 0.05). The postoperative compl ications were that 5 feet were the incision edge shallow putrescence, 1 was the common peroneal nerve hurt, and 1 was the petrous muscle aponeurotic inflammation. Conclusion There is no remarkable difference between the effects of treating intra-articular calcaneal fractures using plate or Kirschner’s wire, but the treatment with Kirschner’s wire is not only much easier and more economical, but has smaller wounds and fewer soft tissue problems.
ObjectiveTo investigate the early-term effectiveness of carpal arthroscopy in the treatment of intra-articular fractures of distal radius.MethodsThe clinical data of 50 cases of intra-articular fractures of distal radius between January 2015 and December 2017 were retrospectively analyzed. According to the different methods of intraoperative assisted treatment, the patients were divided into the trial group (11 cases with carpal arthroscopy assisted treatment) and the control group (39 cases with traditional open reduction). There was no significant difference between the two groups in general data such as gender, age, affected side, cause of injury, time from injury to operation, and preoperative displacement (P>0.05), which were comparable. Six patients in the trial group had triangular fibrocartilage complex (TFCC) injury and received one-stage repair. Postoperative X-ray films were taken to estimate the fracture reduction. Patient-Rated Wrist Evaluation (PRWE) wrist function score and modified Mayo score were used at 3 months after operation to evaluate the function of the wrist. The range of wrist flexion, extension, pronation, and supination motion of the two groups were recorded and compared at 3 months after operation. Patients in the trial group were further divided into the reduction group after arthroscopic exploration (group A, 6 cases) and the simple cleaning group after arthroscopic exploration (group B, 5 cases), and their wrist motions were compared.ResultsThe operation time of the trial group was greater than that of the control group (t=11.08, P=0.00). There was no significant difference in intraoperative blood loss and fracture reduction between the two group (P>0.05). X-ray film at 1 day after operation showed that the degree of fracture displacement was significantly decreased when compared with preoperative one in each group (P<0.05), but no significant difference was found between the two groups at 1 day after operation (t=0.19, P=0.85). Patients in both groups were followed up 8-20 months, with an average of 12 months. There was no significant difference in fracture healing time between the two groups (t=0.52, P=0.60). At 3 months after operation, the PRWE score, modified Mayo score, and wrist motions in the trial group were all better than those in the control group (P<0.05). There was no significant difference in wrist motions between group A and group B (P>0.05). ConclusionCarpal arthroscope assisted treatment of intra-articular fractures of distal radius can achieve good reduction and postoperative function. Meanwhile, TFCC, ligament, articular cartilage, and other injuries can be repaired in one stage.
Objective To compare the effects of operative versus nonoperative treatment for displaced intra-articular calcaneal fractures. Methods All randomized controlled trials (RCTs) of operative versus nonoperative treatment for displaced intra-articular calcaneal fractures were identified. Quality assessment and data extraction were performed by two reviewers independently. Results Four published trials involving 530 patients were included. All studies compared operative with nonoperative treatment. It was clear that operative treatment was superior to nonoperative treatment in terms of helping patients back to work, reducing problems wearing shoes, expanding the range of motion of subtalar joint, and improving the recovery of Bohler’s angle. As for foot pain, there was no difference between the two methods. Because the outcome measures varied across the trials, a meta-analysis could not be performed. Conclusions Both operative and nonoperative treatments produce comparable long-term outcomes in the treatment of displaced intra-articular calcaneal fractures. Because of the poor reporting of outcomes, it is not possible to determine if there is any significant difference in outcome measures apart from those listed above. More trials with high methodological quality are needed.
Objective To investigate the clinical outcome of open reduction and internal fixation of calcaneal interarticular fractures. Methods From August 1998, 38 calcanneal interarticular fractures in 35 cases, including 8 of type Ⅱ, 14of type Ⅲ and 16 of type Ⅳ according to Sander’s classification, were treatedby open reduction to restore the posterior articular facet, subtalar facet, Bohler angle and Gissane’s angle, following internal fixation by plastic titanicalloy plate. Thirtythree calcanneal interarticular fractures were followed up for6 to 22 months, 12.3 months on average; and the healing time and joint functionwere evaluated according to Maryland Foot Score System. Results The average healing time of fracture was 7.1 weeks, ranging from 5 to 12 weeks; and the joint function was excellent in 18 calcanneus, good in 13 calcanneus, and the satisfactory rate was 93.9%. Conclusion Open reduction and internal fixation with plastic titanium plate is a good choice for calcaneal interarticular fractures.
