Objective To explore the effectiveness of computer-aided technology in the treatment of primary elbow osteoarthritis combined with stiffness under arthroscopy. Methods The clinical data of 32 patients with primary elbow osteoarthritis combined with stiffness between June 2018 and December 2020 were retrospectively analyzed. There were 22 males and 10 females with an average age of 53.4 years (range, 31-71 years). X-ray film and three-dimensional CT examinations showed osteophytes of varying degrees in the elbow joint. Loose bodies existed in 16 cases, and there were 7 cases combined with ulnar nerve entrapment syndrome. The median symptom duration was 2.5 years (range, 3 months to 22.5 years). The location of bone impingement from 0° extension to 140° flexion of the elbow joint was simulated by computer-aided technology before operation and a three-dimensional printed model was used to visualize the amount and scope of impinging osteophytes removal from the anterior and posterior elbow joint to accurately guide the operation. Meanwhile, the effect of elbow joint release and impinging osteophytes removal was examined visually under arthroscopy. The visual analogue scale (VAS) score, Mayo elbow performance score (MEPS), and elbow range of motion (extension, flexion, extension and flexion) were compared between before and after operation to evaluate elbow function. Results The mean operation time was 108 minutes (range, 50-160 minutes). All 32 patients were followed up 9-18 months with an average of 12.5 months. There was no other complication such as infection, nervous system injury, joint cavity effusion, and heterotopic ossification, except 2 cases with postoperative joint contracture at 3 weeks after operation due to the failure to persist in regular functional exercises. Loose bodies of elbow and impinging osteophytes were removed completely for all patients, and functional recovery was satisfactory. At last follow-up, VAS score, MEPS score, extension, flexion, flexion and extension range of motion significantly improved when compared with preoperative ones (P<0.05). Conclusion Arthroscopic treatment of primary elbow osteoarthritis combined with stiffness using computer-aided technology can significantly reduce pain, achieve satisfactory functional recovery and reliable effectiveness.
ObjectiveTo summarize the research progress of heterotopic ossification of the elbow joint after trauma. MethodsThe recent domestic and foreign literature concerning heterotopic ossification of the elbow joint after trauma was analysed and summarized. ResultsThe mechanism of heterotopic ossification of the elbow joint after trauma is mainly related to bone morphogenetic protein signal transduction disorder. Now there are many treatments of heterotopic ossification, including non-surgical treatment, prevention, and surgical treatment. Non-surgical treatment and prevention mainly aim at patients who have no elbow heterotopic ossification or who have mild limited elbow motion because of elbow heterotopic ossification after trauma, including drug therapy, radiation therapy, Chinese medicine therapy, and rehabilitation treatment. For patients with invalid non-surgical treatment, choosing surgical treatment is a must. Surgical treatment includes surgical resection, arthroscopic resection, and joint replacement, priority should be given first to surgical resection. ConclusionHeterotopic ossification of the elbow joint is common and there is not a recognized standard treatment, comprehensive use of non-surgical treatment and surgical treatment is the future direction.
Objective To analyse short-term cl inical effect of total elbow arthroplasty in treatment of distal comminuted humeral fracture with serious osteoporosis in geratic patients. Methods From April 2006 to October 2007, five cases of distal comminuted humeral fractures were treated by total elbow arthroplasty with bone cement. Of them, there were 2 males and 3 females, aging 50-76 years old (mean 67.6 years old), including 4 cases of closed fracture and 1 case of open fracture (II type Gustilo-Anderson). All fractures were caused by tumbl ing. According to classification of AO, there were 2 cases of type C1, 2 cases of type C2 and 1 case of type C3. The Barnett index of osteoporosis was 0.40-0.45. The time from injury to operation was 4 to 18 days (mean 7.2 days). The rehabil itation exercise of function was done after 2 days of operation. Results The operative time was from 120 to 180 minutes (mean 150 minutes), the bleeding amount was from 150 to 250 mL (mean 200 mL). All incision achieved primary heal ing. No compl ication occurred. Five cases were followed up for 19 to 36 months (mean 24.5 months). The mean motion range of elbow joint include 141.6° for flection, 6.5° for extention, 10.2° for the degree of ectropion, 81.7° for revolve forward, and 73.8° for revolve behind respectively after 4 months of operation. The length discrepancy of upper l imb was less than 1.5 cm, the muscle force for flexion and extention of finger and wrist was normal. The X-ray films showed that the position of artificial joint was satisfactory without prosthesis dislocation or loosening. According to Mayo elbow performance score, the excellent and good rate was 80% (excellent in 1 case, good in 3 cases, and fair in 1 case). Conclusion Total elbow arthroplasty with bone cement is an effective method in treatment of distal comminuted humeral fracture with serious osteoporosis obviously in the geratic patients, but indication and technique of operation should be mastered strictly.
ObjectiveTo observe the effectiveness of open release combined with distal radius fixation hinged external fixation for the treatment of elbow stiffness.MethodsA total of 77 patients with elbow stiffness caused by trauma were enrolled in this study between October 2014 and October 2015. The patients were divided into control group (39 cases) and observation group (38 cases) by random number table method. The patients in the observation group were treated with elbow joint opening and release combined with distal radial fixation hinged external fixation, while the control group was treated with traditional release. There was no significant difference in gender, age, disease causes, original damage diagnosis, the time from injury to operation, preoperative flexion and extension activity of elbow joint, and preoperative Mayo elbow joint function score between 2 groups (P>0.05). After operation, the function of elbow joint was evaluated by the flexion and extension activity of the elbow joint and the Mayo elbow joint function evaluation standard.ResultsThe incisions healed by first intention in 2 groups. In observation group, there were 1 case infection of nail tract, 2 cases ulnar nerve symptoms, 1 case elbow ossification, and 1 case moderate pain in the elbow; while in control group, there were 2 cases of infection of nail tract, 2 cases of ulnar nerve symptoms, and 3 cases moderate pain in the elbow. The patients in 2 groups were followed up 6 weeks to 12 months, with an average of 6 months. The flexion and extension activity of elbow joint and Mayo elbow joint function score at last follow-up were significantly improved when compared with preoperative ones (P<0.05); at last follow-up, the flexion and extension activity of elbow joint and Mayo elbow joint function score in observation group patients were significantly better than those in control group (P<0.05). According to the Mayo elbow function evaluation standard, the results were excellent in 27 cases, good in 10 cases, and fair in 1 case, with an excellent and good rate of 97.4% in observation group; and the results were excellent in 12 cases, good in 21 cases, fair in 4 cases, and poor in 2 cases, with an excellent and good rate of 84.6% in control group; showing no significant difference between 2 groups (P=0.108).ConclusionOpen release combined with distal radius fixation hinged external fixation can significantly improve the elbow function of patients with traumatic elbow stiffness, its recovery of elbow function was superior to the traditional release.
ObjectiveTo review the research progress of complications associated with open elbow arthrolysis so as to provide clinical reference for complication prevention and treatment. MethodsThe recent publications on open elbow arthrolysis and complications associated with it were extensively reviewed and analyzed. ResultsComplications associated with open elbow arthrolysis include ulnar nerve symptom and neuropathy, elbow instability, heterotopic ossification, and hematoma. Although some progress has been made in the complication prevention and treatment recently, there are still some challenges in the control of surgical trauma, intervention of heterotopic ossification and elbow instability after surgery, as well as postoperative analgesia due to the limitation of surgical techniques and the uncertain mechanism of these complications. ConclusionOpen elbow arthrolysis is safe and effective for elbow stiffness. However, more research on the mechanism of complications should be carried out, to further improve the overall effect of the surgery.
ObjectiveTo compare the effectiveness of transosseous tunnel fixation and drilling fixation for repair of lateral collateral ligament complex (LCLC) in treatment of terrible triad of elbow (TTE).MethodsA clinical data of 50 patients with TTE between June 2012 and January 2018 were retrospectively analyzed. The LCLC was repaired with transosseous tunnel fixation in 22 patients (transosseous tunnel fixation group) and with drilling fixation in 28 patients (drilling fixation group). There was no significant difference between the two groups (P>0.05) in gender, age, fracture side, time from injury to admission, coronoid process fracture classification, radial head fracture classification, and TTE classification. The operation time, intraoperative blood loss, fracture healing time, and complications of the two groups were recorded. At last follow-up, the Mayo elbow performance system (MEPS) score, range of motion of elbow joint, and Broberg-Morrey classification were recorded.ResultsThe operation of two groups were successfully completed. There was no significant difference in the operation time and intraoperative blood loss between the two group (P>0.05). The follow-up time was (24.43±6.84) months in the transosseous tunnel fixation group and (21.55±6.16) months in the drilling fixation group, and the difference was not significant (t=1.534, P=0.132). X-ray films showed that the coronoid process and radial head fractures in the two groups healed, and there was no significant difference in the healing time (P>0.05). At last follow-up, there was no significant difference in the flexion-extension activity, rotation activity, MEPS score, and Broberg-Morrey grading (P>0.05). During the follow-up, there was no re-dislocation or instability of the elbow joint. The incidence of complication was 28.57% (8/28) in the transosseous tunnel fixation group and 27.27% (6/22) in the drilling fixation group, showing no significant difference (χ2=2.403, P=0.121).ConclusionBoth transosseous tunnel fixation and drilling fixation can achieve good results in repair of LCLC for TTE.
【Abstract】 Objective To investigate the methods and effectiveness of arthroscopic poking reduction and percutaneousfixation of radial head fractures. Methods Between August 2002 and May 2010, 15 patients with radial head fractures weretreated using arthroscopic poking reduction and percutaneous fixation with a Kirschner wire. There were 11 males and 4 females with an average age of 29.6 years (range, 17-41 years). The locations were left side in 6 cases and right side in 9 cases. Injuries were caused by falling in 8 cases, by traffic accident in 4 cases, and by sports in 3 cases. The average time from injury to admission was 3.4 days (range, 1-8 days). Of them, 13 patients had Mason type II, and 2 patients had type III fractures. Accompanying injuries were lateral collateral ligament ruptures in 5 patients. Results The X-ray films confirmed good reduction and fracture heal ing. Incisions healed by first intention; no complication occurred, such as neurovascular injury, infection, or hardware failure. All patients were followed up 25 months on average (range, 12-32 months). The flexion-extension arc was (139.0 ± 7.9)° at last follow-up, showing no significant difference when compared with the contralateral (141.0 ± 5.1)° (t=1.146, P=0.271); the range of pronation and supination was (143.3 ± 7.0)° when compared with the contralateral (146.0 ± 4.7)° (t=1.948, P=0.072). The mean Mayo elbow performance score was 92 (range, 80-100); the mean Broberg-Morrey score was 95.2 (range, 85-100); the results were excellent in 12 cases and good in 3 cases. Conclusion Arthroscopic poking reduction and percutaneous fixation with a Kirschner wire offers accurate reduction, rel iable fixation, minimal trauma, rapid recovery, and lower morbidity for Mason type II and selective Mason type III radial head fractures.
ObjectiveTo investigate the feasibility of modified classification of terrible triad of the elbow and the effectiveness of treatment strategy which was chosen by modified classification results. MethodsBetween March 2007 and November 2013, 12 cases of terrible triad of the elbow were treated by operation. There were 5 males and 7 females with an average age of 37.2 years (range, 26-74 years). The mechanism of injury was falling from height in 8 cases and traffic accident in 4 cases. The time from injury to operation was 4 to 11 days (mean, 6.8 days). According to the radial head, coronoid process, olecranon, and medial and lateral collateral ligament complexes injury situation, and based on Mason classification standard and O'Driscoll criteria, the classification standard of terrible triad of the elbow was improved. According to classification results, the approach was determined. The fracture reduction and fixation were performed and soft tissue was repaired. ResultsDehiscence of incision occurred in 1 case and was cured after dressing change; primary healing was obtained in the other patients. All the cases were followed up 19-35 months (mean, 21.6 months). The X-ray films showed fracture healing at 10-17 weeks (mean 12.8 weeks). At last follow-up, the mean flexion-extension arc of the elbow was 117.9° (range, 95-135°) and the mean forearm pronation and supination were 77.1° (range, 70-85°) and 62.5° (range, 45-75°). According to Mayo elbow performance score (MEPS), the results were excellent in 4 cases, good in 5 cases, and fair in 3 cases. One patient had valgus deformity of elbow who refused radial head replacement, and 5 cases had heterotopic ossification of the elbow on the X-ray films. ConclusionThe modified classification of the terrible triad of the elbow is simple and practical, based on the damage assessment of bony structures (radial head, coronoid process, and olecranon) and the soft tissue (medial and lateral collateral ligament complexes). The modified classification can be used effectively for guiding treatment decisions.
