Objective To retrospectively analyze the cl inical effect of l ightbulb operation with nano-hydroxyapatite/ collagen in a consecutive series of patients with osteonecrosis of the femoral head (ONFH). Methods From January 2001to July 2005, 26 patients (35 hips) were treated, 16 males and 10 females, aged 19-54 years old (33.5 on average). The course of disease was 12-36 months (18 months on average). Based on the etiology, 15 cases (22 hips) were steroid induced type, 10 (12 hips) were alcohol induced type and the other one (1 hip ) was idiopathic type. According to the system of Association Research Circulation Osseous (ARCO), there were 6 hi ps of stage IIB, 16 hi ps of stage IIC, 9 hi ps of stage IIIA, 3 hi ps of stage IIIB and 1 hip of stage IIIC. The Harris score was 62.2 ± 7.5. All the patients who had undergone l ightbulb operation with nano-hydroxyapatite/collagen were evaluated both cl inically and radiographically. The bone graft mixture rate of nanohydroxyapatite/ collagen and autogenous bone was 1 ∶ 1, and the mixed bone graft was 6 times of the scraped osteonecrosis volume (30-48 mL). Results The incisions of all 26 patients (35 hi ps) obtained heal ing by first intention. The 2 cases, which got lateral femoral cutaneous nerve injury during the operation, recovered 3-6 months after the operation without any treatment. Another 2 cases got heterotopic ossification 3 months after operation, with no special treatment. All the 26 patients (35 hips) were followed up for 2-7 years (3.5 on average). The patients’ bone heal ing began from the 3rd month after operation. The postoperative Harris score was 85.1 ± 16.2, and there was significant difference compared with the preoperative one (P lt; 0.001). There were 15 hips of excellent, 11 of good, 5 of fair, and 4 of poor which received total hip arthroplasty at the end of the follow-up. According to imaging, 5 hips were progressed from preoperative IIC to IIIA, while the other hips were radiologically stable, with no progress of ONFH. Conclusion Lightbulb operation with nano-hydroxyapatite/collagen provides a surgical treatment to treat early ONFH with satisfactory cl inical outcomes. Nano-hydroxyapatite/collagen is beneficial for the repair and reconstruction of ONFH and suitable for femoral-head-preserving operation for the patients with ONFH of stage II.
ObjectiveTo discuss the effectiveness of operative treatments for different kinds of old injury of extensor tendon in zone II so as to choose the best surgical approach based on the classification of injury. MethodsBetween May 2006 and May 2014, 68 cases of old injury of extensor tendon in zone II were treated. Among them, there were 50 males and 18 females with an average age of 36 years (range, 18-52 years). The causes included contusion injury in 50 cases, avulsion injury in 11 cases, and burn injury in 7 cases. The left side was involved in 21 cases and the right side in 47 cases. The injured finger involved the index finger in 18 cases, the middle finger in 21 cases, the ring finger in 24 cases, and the little finger in 5 cases. The disease duration was 1.5 months to 1 year (mean, 6.75 months). The central slip of extensor was repaired directly in 32 patients who had normal passive motion. Side cross stitch (8 cases) or Littler-Eaton (10 cases) method was used in 18 patients who can not extend actively and passively. Tendon graft was performed in 11 patients with tendon defect. Joint release was given in 7 patients with contracture after burn injury. ResultsPrimary healing of incision was obtained in all cases. Sixty-eight cases were followed up 3-12 months (mean, 6.9 months). Three cases had tendon adhesion in varying degrees and suffered from pain, which was treated conservatively by functional exercise. Recurrence was observed in 2 cases, and extensor tendon was repaired again. According to total active motion (TAM) function assessment, the results were excellent in 52 cases, good in 11 cases, fair in 3 cases, and poor in 2 cases with an excellent and good rate of 92.6%. ConclusionAdaptive operation method for old injury of extensor tendon in zone II should be selected based on the type of injury. The results will be satisfactory if correct method is chosen.
ObjectiveTo observe and study the clinical effect of glucosamine in the treatment of patients with knee articular cartilage injury caused by rheumatoid arthritis. MethodsForty-six patients with knee articular cartilage injury caused by rheumatoid arthritis treated from January 2013 to June 2015 were selected as the research subjects, and they were randomly divided into control group (conventional treatment group, n=23) and observation group (conventional and glucosamine treatment group, n=23) . Then the Noyes classification and serum articular cartilage injury related indexes [cartilage oligomeric matrix protein (COMP), matrix metalloproteinase (MMP)-1, MMP-3 and mouse tissue inhibitors of metalloproteinase (TIMP)-1], inflammatory indexes [tumor necrosis factor (TNF)-α, interleukin (IL)- 17 and IL-33] of the two groups before and after treatment were compared. ResultsIn the observation group, after treatment for 4, 8 and 12 weeks, Noyes grade was better than that in the control group, but with no statistical significance (P ＞ 0.05) . In the observation group, after treatment for 4, 8 and 12 weeks, serum inflammatory markers serum COMP, MMP-1, MMP-3 and TIMP-1 and other related indicators of cartilage damage and serum TNF-α, IL-17 and IL-33 were all significantly lower than those in the control group (P ＜ 0.05) . ConclusionIn the treatment of patients with knee articular cartilage injury caused by rheumatoid arthritis, glucosamine has active role for the improvement of articular cartilage injury and inflammatory stress state of patients.
Objective To compare the effectiveness between locking compression plate (LCP) and locked intramedullary nail (IMN) for humeral shaft fractures of types B and C. Methods Between January 2010 and January 2012, 46 patients with humeral shaft fractures of types B and C were treated, and the clinical data were retrospectively analyzed. LCP was used for internal fixation in 22 cases (LCP group), and IMN in 24 cases (IMN group). There was no significant difference in gender, age, injury causes, the side of fracture, the site of fracture, the type of fracture, associated injury, and time from injury to operation between 2 groups (P gt; 0.05). The regular clinical examination and evaluation of radiography were done. Shoulder function was evaluated by Neer grading system and elbow function was evaluated by Mayo elbow performance score after operation. Results The operation time and intraoperative blood loss in IMN group were significantly lower than those in LCP group (P lt; 0.05). There was no significant difference in hospitalization time between 2 groups (t=0.344, P=0.733). All patients were followed up 16.8 months on average (range, 12-24 months). At 6 months after operation, bone nonunion occurred in 1 patient of LCP group and in 2 patients of IMN group; the bone healing rate was 95.5% (21/22) in LCP group and 91.7% (22/24) in IMN group, showing no significant difference (χ2=0.000, P=1.000). Except for nonunion patients, the bone healing time was (11.77 ± 0.75) weeks in LCP group and (11.38 ± 0.82) weeks in IMN group, showing no significant difference (t=1.705, P=0.095). Between LCP and IMN groups, significant differences were found in radial nerve injury (4 cases vs. 0 case) and impingement of shoulder (0 case vs. 6 cases) (P lt; 0.05), but no significant difference in superficial infection (1 case vs. 0 case) and iatrogenic fracture (1 case vs. 2 cases) (P gt; 0.05). There was no significant difference in shoulder function and elbow function at 1 year after operation between 2 groups (P gt; 0.05). Conclusion LCP fixation and IMN fixation for humeral shaft fractures of types B and C can achieved satisfactory results. More attention should be paid to avoiding radial nerve injury by fixation of LCP; nail tail should be buried deeply into the cortex of the greater tuberosity and rotator cuff should be protected to decrease the rate of impingement of shoulder by fixation of IMN.
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 improve the retrograde rotative-type interlocking intramedullary nail based on humeral bone dissection and cl inical appl ication, and investigate the cl inical values of modified retrograde rotative-type interlocking intramedullary nail for humeral shaft fracture. Methods Between March 2006 and March 2010, 146 patients with humeral shaft fractures were treated and fractures were fixed with the modified retrograde rotative-type interlocking intramedullary nail (the modified group, n=73) and with the retrograde rotative-type interlocking intramedullary nail (the original group, n=73). In the original group, there were 40 males and 33 females with an average age of 41 years; 41 cases were classified as transversefracture, 18 as obl ique fracture, 8 as spiral fracure, and 6 as comminuted fracture; the median disease duration was 11 days (range, 3 hours to 2 months); and close reduction fixation was performed in 27 cases and open reduction fixation in 46 cases. In the modified group, there were 39 males and 34 females with an average age of 40 years; 43 cases were classified as transverse fracture, 16 as obl ique fracture, 10 as spiral fracure, and 4 as comminuted fracture; the median disease duration was 13 days (range, 3 hours to 3 months); and close reduction fixation was performed in 31 cases and open reduction fixation in 42 cases. There was no significant difference in sex, age, fracture type, and disease duration between 2 groups (P gt; 0.05). The fracture heal ing and functional recovery of affected l imbs were compared between 2 groups after operation. Results The operation time and intraoperative blood loss in the modified group were significantly less than those in the original group (P lt; 0.05). Iatrogenic fracture occurred in 3 cases of the original group, which were cleavage fracture of supracondylar. No iatrogenic fracture occurred in the modified group. All incisions of 2 groups healed by first intention without compl ications of postoperative infections, metal fracture, and loosening of internal fixation, etc. A total of 116 patients were followed up more than 12 months in 2 groups with 58 patients in each group. The fracture heal ing time was (15 ± 3) weeks (fresh fracture) and (30 ± 12) weeks (old fracture and nonunion) in the modified group, and was (16 ± 4) weeks (fresh fracture) and (35 ± 14) weeks (old fracture) in the original group, showing significant differences between 2 groups (P lt; 0.05). The results of Neer shoulder score were excellent in 65 cases and good in 8 cases, and the results of Aitken and Rorabeck elbow function score were excellent in 61 cases and good in 12 casesin the original group; the results of Neer shoulder score were excellent in 67 cases and good in 6 cases, and the results of Aitken and Rorabeck elbow function score were excellent in 63 cases and good in 10 cases; and the excellent and good rates were 100% in 2 groups. Conclusion The modified retrograde rotative-type interlocking intramedullary nail has the advantages of easy operation and less compl ication, which is an effective and rel iable internal fixator.
Lumbar disc herniation is one of the most common causes of low back and leg pain in clinic. There are a lot of non-surgical therapeutic methods widely used in clinic for treating lumbar disc herniation. The author assessed the available systematic reviews of non-surgical methods in treating lumbar disc herniation which had been published in these years, and finally a total of 13 systematic reviews were retrieved including 1 about conservative treatments, 8 Chinese medicine treatments, and 4 percutaneous treatments, such as chemonucleolysis and epidural steroid injection. The results showed that the conservative treatments included injections, traction, physical therapy, bed rest, manipulation, medication, and acupuncture. But no evidence was found to show that any of the above treatments was clearly superior to others including no treatment for patients with lumbar disc herniation. The outcomes from some reviews showed that Chinese medicine treatments were safer and comprehensive treatment of traditional Chinese medicine was relatively effective compared with single treatment. Electro-acupuncture, compared with conventional therapy (bed rest, waist protection, pelvic traction, manual or physical therapy) and oral medications as well, was safe and effective in alleviating pain and improving overall function. Chinese medicinal fumigation combined with traction was more effective than single treatment. Percutaneous treatment of chemonucleolysis had much better short-term effectiveness. Percutaneous epidural steroid injection also had certain effects. To summarize, Chinese medicine and percutaneous treatments may be effective in treating lumbar disc herniation. However, more clinical trials are needed, since current evidence is of low quality.
ObjectiveTo investigate the clinical effect and the incidence of postoperative complications of Milligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids.MethodsProspectively collected 120 patients with annular mixed hemorrhoids who received treatment from the Department of Colorectal Surgery of Bazhong Hospital of Traditional Chinese Medicinel during the April, 2016 to October, 2018. All of the 120 patients with annular mixed hemorrhoids were randomly divided into the experimental group and the control group, with 60 patients in each one group. Patients in the experimental group was treated with Milligan-Morgan hemorrhoids combined with reducing tension of alary incision, while patients in the control group with conventional Milligan-Morgan hemorrhoid.ResultsIn the experimental group, 49 cases were cured, 11 cases showed obvious effect; in the control group, 39 cases were cured, 20 cases showed obvious effect, and 1 case was effective. The curative effect in experimental groups was better than that of the control group (Z=–2.090, P=0.037), and the effective rates of these two group were both 100% in total. The mean healing time was (19±3) d (14–21 d) in the experimental group and (21±3) d (14–24 d) in the control group, respectively, which was better in the experimental group (Z=–13.636, P<0.001). Experimental group with lower score of wound pain, hemafecia, and anal margin edema, which were much better than control group on 1 d and 3 d after operation (P<0.05). There was no statistically significant differences on incidence of uroschesis and recurrence rate between the two groups (P>0.05).ConclusionsMilligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids has good clinical effect and deserves clinical application.
