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 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 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 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 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.
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 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.
ObjectiveTo investigate the methods and the effectiveness of arthroscopic treatment combined with repair of the cyst wall using the tendon flap of medial head of gastrocnemius muscle after resection of popliteal cyst. MethodsA retrospective analysis was made on the clinical data of 140 patients with popliteal cyst between August 2009 and June 2014, including 44 males and 96 females with a mean age of 54.68 years (range, 14-80 years). The median course of symptoms was 31 months (range, 20 days to 30 years). According to Rauschning and Lindgren criteria for popliteal cyst grade, 4 cases were rated as grade Ⅰ, 44 cases as grade Ⅱ, and 92 cases as grade Ⅲ. The preoperative Lysholm knee score was 68.99±8.23. Firstly, cyst was resected, then the hernia sac of joint capsule was repaired with the tendon flap of medial head of gastrocnemius muscle, and finally a knee arthroscopy was used for the diagnosis and treatment of intra-articular lesions. ResultsNo complication of nerve or blood vessel injury, infection, or necrosis occurred. The mean follow-up was 26 months (range, 6-64 months). During follow-up, 1 case (0.71%) had cyst recurrence. According to Rauschning and Lindgren criteria for popliteal cyst grade, 37 cases were rated as grade 0, 92 cases as grade Ⅰ, 10 cases as grade Ⅱ, and 1 case as grade Ⅲ at 6 months after operation, showing significant difference when compared with preoperative one (Z=-14.303, P=0.000); the Lysholm knee score (85.51±9.23) was significantly higher than preoperative score (t=-15.798, P=0.000). ConclusionArthroscopic treatment combined with repair of the cyst wall with the tendon flap of medial head of gastrocnemius muscle after resection of popliteal cyst is a better way to avoid recurrence.
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.
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.
