There were 16 males and 5 females with an average age of 28 years old(ranged 17-60 years). All of the patients was combined with incompetence of abduction function ofshoulder, 6 cases with incompotence of extenxor function of elbow and 11 cases with incompotence ofsupifiation fu...
Objective To evaluate the short-term results of reconstruction of stiff elbow under arthroscopy technique in patients with elbow osteoarthritis. Methods Between March 2006 and March 2009, 38 cases of elbow osteoarthritis with contracture were treated under arthroscopy technique. There were 26 males and 12 females with an average age of 47.8 years (range, 26-66 years). Unilateral side was affected in all cases, including 13 cases at the left side and 25 at the right side with 30 patients on the dominant side. The disease duration was more than 6 months. X-ray examination showed that 31 patients had free body, and 28 had osteophytosis. Seven patients had ulnar neuritis. The arthroscopy functional reconstruction was performed including synovectomy, free body removal, and osteocapsular arthroplasty. Results All incisions healed by first intention. All patients were followed up 6-10 months (mean, 8 months). Transient radial nerve injury occurred in 1 case, re-adhesion of elbow joint in 1 case, and heterotopic ossification of brachial ulnar joint in 1 case at 6 months after operation. In 1 patient compl icated by ulnar neuritis, the disorder of ulnar nerve was not improved, nervous symptoms disappeared after the re-operation of ulnar nerve relaxation after 2 months. The range of motion, Mayo Elbow Performance Score (MEPS), and visual analogue scale (VAS) for pain at 3 and 6 months had significant differences when compared with those before operation (P lt; 0.05), but had no significant difference between two time points after operation (P gt; 0.05). According to MEPS functional criteria, the results were classified as excellent in 20 cases, good in 15 cases, fair in 2 cases, and poor in 1 case at 6 months after operation, and the excellent and good rate was 92.1%. No new free body or osteophytosis occurred after operation by X-ray examination. Conclusion The arthroscopy is an effective technique to reconstruct the function of stiff elbow, which can obviously improve the range of motion and the function of elbow joint, and has good short-term results.
Objective To retrospectively reviewed the operative therapy of the terrible triad of the elbow. Methods From October 2003 to September 2007, 10 cases of terrible triad were treated, with an elbow dislocation and an associated fracture of both the radial head and the coronoid process. There were 3 males and 7 females with the age of 18-66 years. The injury was caused by traffic accidents in 4 cases, fall ing from a height in 4 cases, and tumbl ing in 2 cases. The coronoid process fractures of the patients were 5 cases of type I, 3 cases of type II and 2 cases of type III according to Regan- Morrey classification. The radial head fractures of the patients were 1 case of type I, 6 cases of type II and 1 case of type IIIaccording to Mason classification, and their radial heads of the other 2 patiants were resected before they were in hospital. The general approach was to repair the damaged structures sequentially from deep to superficial, from coronoid to anterior capsule to radial head to lateral l igament complex to common extensor origin. And selected cases were repaired of the medial collateral l igaments and assisted mobile hinged external fixation to keep the forearm fixed in functional rotation position. The function of the elbows were evaluated with the criteria of the HSS2 score system. Results The other wounds healed by first intention except 1 case which had infection 7 days after operation and whose soft tissue defect in posterior elbow were repaired with the pedicle thoracoumbil ical flap. The patients were followed up 6 to 51 mouths (mean 24.9 mouths). The fracture heal ing time was 6 to 20 weeks (mean 9.6 weeks). Six mouths postoperatively, the mean flexion-extension arc of the elbow was 106.5° (85-130°), and the mean pronation-supination arc of the forearm was 138°( 100-160°) respectively. According to the criteria of the HSS2 score, the results were excellent in 4 cases, good in 4 cases, and fair in 2 cases. No compl ications such as stiffness and ulnohumeral arthrosis occurred. The radial nerve injury was found in 1 patient 1 day after operation who was treated with neurolysis, and the nerve function was recovered after 4-6 months. And heterotopic ossification occurred in 6 patients 6 months after operation and radiographic subluxation developed in 1 patient 36 months after operation, and conservative treatment weregiven. Conclusion The terrible triad of the elbow can lead to serious elbow instabil ity and should be treated with operationto restore the anatomic structures, to repair the articular capsule and the collateral l igament, using the adjuvant hinged external fixation and early exercise to avoid immobil ization and recover the articular function.
Objective To review the basic research and cl inical progress of elbow heterotopic ossification after injury. Methods The recent l iterature concerning heterotopic ossification of the elbow was reviewed. Results Heterotopic ossification was caused by variety of stimul i and conditions. The current methods of prevention and treatment were to improve surgical techniques, to reduce trauma and bleeding, to rinse the area with bone fragments with plenty of salt water, and to use non-steroidal anti-inflammatory drugs. Conclusion Once heterotopic ossification occurred, surgical treatment is unique treatment method, so emphasis is to prevent heterotopic ossification.
Objective To evaluate the effectiveness of the AO anatomical locking compression plate in treating type C distal humeral fracture. Methods Between July 2008 and April 2009, 13 cases of type C distal humeral fracture were treated with the AO anatomical locking compression plates. There were 5 males and 8 females with an average age of 52.1 years (range, 24-80 years). Fractures were caused by tumbl ing in 7 cases, by traffic accident in 4 cases, and by fall ing from height in2 cases. According to Association for Osteosynthesis/Orthopaedic Trauma Association (AO/OTA) classification, there were 3 cases of type C1, 6 cases of type C2, and 4 cases of type C3. Two cases compl icated by ulnar nerve injuries, 1 by radial nerve injury, 2 by fractures of ulnar olecranon, 3 by fractures of other parts of extremities, and 6 by osteoporosis. The time from injury to hospital ization ranged from 3 hours to 4 days (0.9 day on average). Results All the incisions achieved heal ing by first intention. Thirteen cases were followed up 12 to 21 months with an average of 15.9 months. According to the X-ray films, unions were achieved both at fracture site and the olecranon osteotomy site with a heal ing time of 8 to 13 weeks (10 weeks on average). The function of elbows recovered from 3 to 32 weeks (10 weeks on average). No fixation failure, myositis ossifican, delayed union, or malunion occurred during the follow-up. The Mayo Elbow Performance score ranged from 75 to 100 with an average score of 95.8; the results were excellent in 9 cases, good in 3 cases, and fair in 1 case with an excellent and good rate of 92.3%. Conclusion The AO anatomical locking compression plate has a good fixation in treating type C distal humeral fracture. Through the approach of olecranon osteotomy, it is easy to get anatomical reduction, stable fixation, and early exercise.
Objective To explore the operation procedure and effectiveness of terrible triad of the elbow joint. Methods Between October 2006 and June 2010, 11 cases of closed terrible triad of the elbow joint were treated by operation. There were 8 males and 3 females with an average age of 32 years (range, 21-53 years). The mechanism of injury was fall ing from height in 4 cases and traffic accident in 7 cases. The time from injury to admission was 30 minutes to 9 days. According to Regan-Morrey classification for fractures of the ulnar coronoid, there were 5 cases of type I, 5 cases of type II, and 1case of type III; and according to Mason classification for fractures of the radial head, there were 4 cases of type I, 5 cases of type II, and 2 cases of type III. The elbow joint range of motion (ROM) was (63 ± 9)° at flexion and extension, and the forearm ROM was (71 ± 8)° at pronation and supination. All cases underwent reduction and fixation by lateral approach combined with medial approach according to McKeeps operation process. After operation, the affected l imb was immobil ized with plaster at elbow joint flexion of 90° and in forearm neutral position, then passive physical exercises were carried out, and finally active physical exercises were done after removing plaster at 4 weeks. Results All incisions healed by first intention. Eleven cases were followed up 7-27 months (14.5 months on average). The X-ray films showed good reduction, the cl inical heal ing time was 8-19 weeks with an average of 11 weeks. Mild ectopic ossification of the elbow joint occurred in 3 cases at 6 months after operation, mild degenerative change in 1 case at 18 months after operation. At last follow-up, the elbow joint ROM was (103 ± 14)° at flexion and extension, and the forearm ROM was (122 ± 13)° at pronation and supination, showing no significant difference when compared with the values of normal elbow joint (P gt; 0.05) and significant difference when compared with the preoperative values of affected elbow joint (P lt; 0.05). According to Mayo elbow performance score, the results were excellent in 5 cases, good in 5 cases, and fair in 1 case with an excellent and good rate of 90.9%. Conclusion The surgical treatment of terrible triad of the elbow joint can restore sufficiently elbow stabil ity, allow early motion postoperatively, and enhance the functional outcome.
Objective To investigate the method and effectiveness of operative treatment of Dubberley type 3B capitulum-trochlea fractures. Methods Between January 2009 and December 2012, 8 cases of Dubberley type 3B capitulum-trochlea fractures were treated. There were 2 males and 6 females with an average age of 55 years (range, 43-65 years). The injury was caused by falling in 6 cases, electric bicycle accident in 1 case, and traffic accident in 1 case. All fractures were fresh and closed injury. No neural or vascular injury was found. The time between injury and operation was 3-15 days (mean, 5.9days). Olecranon osteotomy was performed by a posterior midline skin incision of the elbow; 3.0 mm Herbert compression screws placed from posterior to anterior, 2.4 mm L shape locking compression plate designed for distal radius or 2.7 mm anatomical locking compression plate designed for distal humerus and 1.0 mm Kirschner wires or 3.0 mm Herbert screw for the transverse and coronal plane in the subchondral of anterior articular surface were used for fixation; and the lateral and medial collateral ligaments were repaired. Results All incisions healed by first intention. The patients were followed up 12-18 months (mean, 14.5 months). The X-ray films showed that fracture healing was achieved at 12-24 weeks (mean, 15 weeks) in 7 cases. Fracture nonunion and partial bone resorption in the capitellum were observed in 1 case. No failure of internal fixation, ulnohumeral joint instability, or traumatic arthritis occurred. At last follow-up, the range of motion of injured elbow was 0-40° in extension (mean 25.0°), 100-135° in flexion (mean, 116.3°), 60-70° in pronation (mean, 61.3°), and 80-90° in supination (mean, 81.3°). The elbow function score was 64-96 (mean, 81.1) according to the Broberg-Morrey evaluation criteria; the results were excellent in 2 cases, good in 4 cases, and fair in 2 cases with an excellent and good rate of 75%. The visual analogue scale (VAS) score was 0-3 (mean, 1). Conclusion For Dubberley type 3B capitulum-trochlea fractures, an early anatomic reconstruction of capitellar and trochlea, repair of the medial and lateral collateral ligament, and early active mobilization can obtain good functional results.
【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.
Objective To evaluate the clinical effect of periosteal autograft in repair of ankylosis of elbow joint. Methods From May 1985 to November 1999, 18 cases of elbow joints ankylosis (6 cases of osteo-ankylosis, 12 cases of fibroankylosis) were treated by repairing articular surface with periosteal autografting. Out of 18 cases, 13 were caused by old dislocation and fracture of elbow joints, 3 by late rheumatoid arthritis, and 2 by old total joint tuberculosis. In this surgical approach, periosteum from upper end of tibia was transplanted into articular surface after correction of the elbow joint from ankylosis deformity, and continuous passive or active movement of the operated joint was adopted with skeletal traction through olecranon of ulna for 4 weeks after operation. All of the cases were followed up for 1-9 years, 5.2 years on average, before clinical evaluation. Results The elbow joints in 11 cases were restored to normal, the joints in 4 cases obtained active movement in the range of 100°-0°, and thejoints in the other 3 cases could only have limited movement because of severe muscular atrophy. Conclusion The articular surface in arthroplasty of elbow joint ankylosis could be effectively repaired by periosteal autograft, and the function of the joints could be obviously improved by continuous movement of the joints after operation with skeletal traction.
【Abstract】 Objective To evaluate the cl inical effect of excising the radial head, repairing or reconstructing themedial collateral l igament (MCL) in treating comminuted fracture of the radial head accompanying by MCL injury. Methods From September 2000 to April 2006, 18 patients with comminuted fractures of radial head accompanying by MCL injury were treated by excision of the radial head, repair or reconstruction of the MCL. Of them, there were 12 males and 6 females,aged 21 to 57 years. Injury was caused by high fall ing in 10 cases and by traffic accidents in 8 cases. According to Mason classifications,13 fractures were of type Ⅲ and 5 of type Ⅳ . Fifteen cases of fresh fractures were operated within 2 weeks, 3 cases of old fractures at 4, 6, and 14 months after injury respectively. Four cases underwent MCL repair and 14 cases underwent MCL reconstruction. Results All the 18 cases were followed up 1-5 years (mean 3 years ). According to Broberg and Morrey scoring system, 4 patients were rated as excellent, 12 as good, 1 as fair, and 1 as poor. The excellent and good rate was 88.9%.Three patients had l ight pain of elbow, 1 patient had moderate pain and the other 14 had no pain. The range of elbow motion was from 110 to 140°(mean 130°). The pronation averaged 75° (35-85°). The supination averaged 80° (65-89°). Compared with normal l imbs, the grip strength decreased by 3% to 28% (mean 15%); the extension strength decreased by 8% to 39% (mean 30%); the flexion strength decreased by 7% to 29% (mean 18%); the pronation strength decreased by 7% to 31% (mean 20%);the supination strength decreased by 15% to 45% (mean 25%). The X-ray films showed that carrying angle increased by 0 to 11°(mean 5° ) under two-newton-meter valgus torque. There were significant differences between injured l imbs and normal l imbs (P lt; 0.05). Conclusion The MCL was the primary valgus stabil izer of the elbow. If the radial head replacement could not becarried out, the repair or reconstruction of the medial collateral l igament was effective.
