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 investigate the diagnose and treatment of intra-articular fracture of the 5th metacarpale base with carpometacarpal joint dislocation (reverse Bennett fracture). Methods Between January 2008 and March 2012, 26 cases of reverse Bennett fracture were treated. There were 20 males and 6 females, aged 19-48 years (mean, 26 years). The injury causes included boxing injury in 19 cases, falling injury in 3 cases, heavy pound injury in 3 cases, and crushing injury in 1 case. According to Lundeen classification, there were 8 cases of type A, 9 cases of type B, 3 cases of type C, and 6 cases of type D. The time from injury to operation ranged 1-8 days with an average of 4 days. All patients underwent open reduction and internal fixation with Kirschner wires, screws, or plates by L-shaped dorsal incision. Results Primary healing was obtained in all incisions; no infection, hematoma, and necrosis occurred after operation. All patients were followed up with an average time of 12.5 months (range, 8-24 months). X-ray films showed that all fractures healed after 6-8 weeks (mean, 6.5 weeks); no delayed union or nonunion and no the 5th carpometacarpal joint dislocation were observed. Two cases had mild osteoarthritis. According to the upper extremity functional evaluation standard by Hand Surgery Branch of Chinese Medical Association, the results were excellent in 22 cases, good in 3 cases, and fair in 1 case, with an excellent and good rate of 96.2%. Conclusion For patients with reverse Bennett fracture, good results can be obtained if early diagnose is done and appropriate internal fixation is selected.
OBJECTIVE: To investigate the treatment results of fracture involved articular surface with absorbable screws and rods. METHODS: From October 1995 to May 2002, 32 patients with fracture involved articular surface were treated with absorbable screws and rods with the materials of SR-PGA and SR-PLLA. Bone traction or plaster external fixation were carried out postoperatively. RESULTS: The followed-up period varied from 3 months to 78 months, with an average of 18.5 months. According to the articular function evaluation criteria, the results were excellent in 24 patients, good in 6 patients and fair in 2 patients. The excellent and good rate was 93.7%. The fractures healed, without dislocation, infection and local effusion. CONCLUSION: Internal fixation of absorbable screws and rods is a perfect procedure for treating fracture involved articular surface, which avoided the pain of taking out internal fixation materials of the second operation.
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 investigate the effect of ultrasound-guided intra-articular injection of shoulder joint combined with hydraulic dilatation in the treatment of frozen shoulder in different clinical stage. Methods The clinical data of patients with frozen shoulder diagnosed in Zigong Fourth People’s Hospital from January 2020 to January 2021 were collected retrospectively. The patients were divided into three groups according to the clinical stage of frozen shoulder (stage Ⅰ, stage Ⅱ and stage Ⅲ). All patients volunteered to receive ultrasound-guided intra-articular injection of shoulder joint combined with hydraulic dilatation for 3 consecutive times, with a 2-week interval for each treatment, and followed up for 6 months. Before treatment and 2 weeks, 4 weeks, 2 months, 4 months and 6 months after treatment, the patients were scored with Visual Analog Scale (VAS) and Active Range of Shoulder Motion (AROM), and the capsule thickness of shoulder were measured, respectively. Results A total of 150 patients were included, including 61 patients in stage Ⅰ, 74 patients in stage Ⅱ and 15 patients in stage Ⅲ. The thickness of shoulder joint capsule on the affected side was thicker than that on the healthy side (t=24.384, P<0.001). After treatment, the thickness of shoulder joint capsule and VAS score decreased (P<0.05), and the AROM score increased (P<0.05). Before treatment, the thickness of shoulder joint capsule in stageⅡpatients was higher than that in stageⅠand Ⅲ patients [(4.3±1.0) vs. (2.9±0.5) vs. (3.1±0.4) mm; F=57.195, P<0.001]. Four weeks, 2 months, 4 months and 6 months after treatment, the decrease of shoulder joint capsule thickness was the largest in stageⅡpatients (P<0.05). Compared with stageⅡand Ⅲ patients, stageⅠpatients had the highest VAS score before treatment (7.7±0.7 vs. 5.1±0.8 vs. 4.5±0.7; F=233.560, P<0.001). There was no significant difference in VAS scores among the three groups 4 weeks (F=1.679, P=0.190), 4 months (F=1.348, P=0.263) or 6 months (F= 0.940, P=0.393) after treatment, while there were significant differences in VAS scores among the three groups 2 weeks (F=66.924, P<0.001) and 2 months (F=9.598, P<0.001) after treatment. Compared with stageⅠand Ⅲ patients, stageⅡpatients had the lowest AROM score before treatment (15.2±1.8 vs. 23.5±1.9 vs. 26.1±3.5; F=343.718, P<0.001). Four weeks (F=0.034, P=0.967), 2 months (F=0.222, P=0.801), 4 months (F=0.634, P=0.532) or 6 months (F=0.001, P=0.999) after treatment, there was no significant difference in AROM scores among the three groups, while there was significant difference in AROM scores among the three groups 2 weeks after treatment (F=177.135, P<0.001).Conclusions Ultrasound-guided intra-articular injection of shoulder joint combined with hydraulic dilation has good efficacy in the treatment of frozen shoulder in different clinical stage. Early injection treatment can shorten the course of the disease and relieve the pain of patients during the course of the disease.
ObjectiveTo evaluate the effectiveness of intra-articular radioulnar ligament reconstruction in the treatment of chronic instability of the distal radioulnar joint. MethodsBetween January 2006 and June 2012, the intra-articular radioulnar ligament reconstruction was used to treat chronic instability of the distal radioulnar joint in 12 patients. Of 12 cases, 8 were males and 4 were females with an average age of 37.3 years (range, 22-54 years). The causes of injury were tumble in 9 patients, traffic accident in 2 patients, and sprain in 1 patient. The average time from initial injury to operation was 6.2 months (range, 2-13 months). The pain and function of the wrists were assessed with Patient-Rated Wrist Evaluation (PRWE) (27.5±4.7). Broadening of the distal radioulnar joint space was seen on the anteroposterior radiograph in all the patients. Lateral view showed dorsal instability in 10 patients and palmar instability in 2 patients. There was no radial fracture, ulnar fractures or degeneration of the distal radioulnar joint. ResultsAll patients achieved primary healing of incision. No complication of deep infection or nerve injury occurred. They were followed up from 12 to 30 months (mean, 20.6 months). Pain and the clicking sound of the wrists disappeared; grip strength increased; the range of motion values of the wrist and forearm were restored. PRWE score was 5.8±2.1 at last follow-up, showing significant difference when compared with preoperative score (t=14.215, P=0.000). Imaging examination showed good appositions of the distal radioulnar joint, with no dislocation or subluxation. ConclusionIntra-articular radioulnar ligament reconstruction can rebuild the anatomic stability of the distal radioulnar joint, which does not damage the adjacent structures of the joints and can obtain satisfactory function of the reconstructed joint. It is a good choice for chronic instability of the distal radioulnar joint without articular degeneration.
Objective To evaluate the effects of T-shaped plate internal fixation in treatment of intra-articular fracture of distal radius. Methods From January 2005 to March 2008, 52 cases of intra-articular fracture of distal radius were treated, including 32 males and 20 females and aging 21-60 years old (mean 47 years old). Fracture was caused by tumbl ing in 30 cases, by fall ing from height in 8 cases, by traffic accident in 11 cases, and by a crashing object in 3 cases. Of 52 cases,there were 50 cases of closed fracture and 2 cases of open fracture. According to AO standard of classification, there were 14 cases of B2 type, 16 cases of B3 type, 15 cases of C1 type, 6 cases of C2 type, and 1 case of C3 type. According to the Cooney’ s general standard of classification of unstable fracture, there were 5 cases of type II, 10 cases of type III, and 37 cases of type IV. The time from injury to operation was 3-14 days (mean 5 days). All patitents received open reduction and T-shaped plate fixation. Seven patients having bone defect were given 6-15 g autologous il ium or 5 mL calcium sulphate artificial aggregate after reduction. Results All incisions healed by first intention. All the patients were followed up for 15 to 30 months postoperatively (mean 24 months). The X-ray films showed good anatomical reduction, even articular surface and no lossening of internal fixation in all the cases. The fractures healed within 9-15 weeks after operation (mean 12 weeks). At last follow-up, the mean palmar tilt was 8° and the mean ulnar variance was 21°, showing statistically significant differences when compared preoperation (— 5° and 5°, P lt; 0.05). The radial length were not abbreviated. According to Dienst assessment, the results were excellent in 42 cases, good in 3 cases, fair in 5 cases and poor in 2 cases 12 weeks after operation, and the excellent and good rate was 86.5%. Conclusion T-shaped plate fixation is rel iable and effective in treatment of intra-articular fracture of distal radius because it has less coml ication of infection, loosening of internal fixation, reduction failure and tendon rupture.
Objective To evaluate the analgesic effect of intra-articular ropivacaine with lidocaine. Methods A double-blind randomized controlled trial was conducted. Ninety patients receiving selective knee arthroscopy were randomized into three groups of 30 patients. At the end of the operation, before the release of the tourniquet, an intra-articular injection was administered to each patient through arthroscope, in accordance with their random allocation: 0.9% normal saline (normal saline group); 100 mg ropivacaine (ropivacaine alone group) and 100 mg ropivacaine and 100 mg 2% lidocaine (ropivacaine with lidocaine group). Pain intensity was assessed after the operation using the 100-mm visual-analog scale (VAS), and the amount of supplemental analgesics used within the following 24 hours were recorded. Results The VAS scores of 2 hours postoperatively at rest, and 1, 2, 4, and 8 hours postoperatively at motion, were significantly higher in the normal saline group than in ropivacaine alone group (Plt;0.05). The VAS scores 0.5, 1 and 2 hours postoperatively at rest, and at the awaking moment, 0.5, 1, 4, 8, and 24 hours postoperatively at motion, were significantly higher in the normal saline group than in ropivacaine with lidocaine group (Plt;0.05). Conclusion Intra-articular ropivacaine can reduce a patient’s pain after operation. The combination of lidocaine with intra-articular ropivacaine can reduce the patient’s pain severity immediately after the operation and achieve an early analgesic effect.
ObjectiveTo compare extra-articular and intra-articular olecranon osteotomy in treating intercondylar fractures of the distal humerus managed with open reduction and internal fixation regarding the functional outcomes and complications. MethodsBetween September 2008 and December 2010, 36 patients with intercondylar fractures of the distal humerus were treated by open reduction and internal fixation using the trans-olecranon approach. Among the, 21 underwent extra-articular olecranon osteotomy and 15 accepted intra-articular olecranon osteotomy. The mean follow-up time was three years. We compared the elbow function, the rate of no non-union or delayed union and the rate of postoperative complications between the two groups. ResultsThe elbow function and Mayo elbow performance scores were good at the latest follow-up. There was no non-union in all osteotomies. We found significant difference in delayed union (P=0.01) and traumatic arthritis rate (P=0.02) between the two groups. ConclusionExtra-articular olecranon osteotomy is better for bone union and the decrease of traumatic arthritis rate.
Objective To investigate the treatment and therapeutic efficacy of intra-articular meniscal cysts by arthroscopy. Methods From January 2005 to December 2009, 9 cases of intra-articular meniscal cysts were treated by arthroscopy, including 5 males and 4 females, with an average age of 33.8 years (range, 24-46 years). Six patients suffered in left knees, 3 in right ones. Just 1 case had trauma history, the others had no obvious predisposing causes. The average course of the disease was 24.2 months (range, 4-36 months). The Lysholm score was (74.2 ± 11.6) points. Arthroscopy showed that the locations of cysts were the anterior horn of lateral meniscus in 8 cases and the anterior horn of medial meniscus in 1 case; all being single cyst (of them, 3 being multilocular cyst). Results All incisions healed primarily with no compl ications of infection and joint effusion. All 9 patients were followed up from 3 to 48 months with an average of 12.7 months. Preoperative symptoms disappeared or reduced and the range of motion of the knee returned to normal. TheLysholm score was (95.1 ± 3.4) points after 3 months of operation, showing significant difference (P lt; 0.01) when compared with the socre before operation. According to assessment standard described by Choy, the treatment outcome was excellent in 6 cases, good in 2 cases, and general in 1 case; the excellent and good rate was 88.9%. No recurrence was found during follow-up. Conclusion Arthroscopic surgery shows the advantages to maintain good function of knee for the treatment of meniscal cyst, it is the best choice for intra-articular meniscal cysts because of its mini-trauma, rapid recovery, thorough treatment and less recurrence. Simultaneously, partial or tatol meniscectomy or menicus repairing under arthroscopy is performed.
