Objective To evaluate the effectiveness of limited internal fixation combined with a hinged external fixator in the treatment of peri-elbow bone infection. Methods The clinical data of 19 patients with peri-elbow bone infection treated with limited internal fixation combined with a hinged external fixator between May 2018 and May 2021 were retrospectively analyzed. There were 15 males and 4 females with an average age of 44.6 years (range, 28-61 years). There were 13 cases of distal humerus fractures and 6 cases of proximal ulna fractures. All the 19 cases were infected after internal fixation of fracture, and 2 cases were complicated with radial nerve injury. According to Cierny-Mader anatomical classification, 11 cases were type Ⅱ, 6 cases were type Ⅲ, and 2 cases were type Ⅳ. The duration of bone infection was 1-3 years. After primary debridement, the bone defect was (3.04±0.28) cm, and the antibiotic bone cement was implanted into the defect area, and the external fixator was installed; 3 cases were repaired with latissimus dorsi myocutaneous flap, and 2 cases were repaired with lateral brachial fascial flap. Bone defects repair and reconstruction were performed after 6-8 weeks of infection control. The wound healing was observed, and white blood cell (WBC), erythrocyte sedimentation rate (ESR), and C-reaction protein (CRP) were reexamined regularly after operation to evaluate the infection control. X-ray films of the affected limb were taken regularly after operation to observe the bone healing in the defect area. At last follow-up, the flexion and extension range of motion and the total range of motion of the elbow joint were observed and recorded, and compared with those before operation, and the function of the elbow joint was evaluated by Mayo score. Results All patients were followed up 12-34 months (mean, 26.2 months). The wounds healed in 5 cases after skin flap repair. Two cases of recurrent infection were effectively controlled by debridement again and replacement of antibiotic bone cement. The infection control rate was 89.47% (17/19) in the first stage. Two patients with radial nerve injury had poor muscle strength of the affected limb, and the muscle strength of the affected limb recovered from grade Ⅲ to about grade Ⅳ after rehabilitation exercise. During the follow-up period, there was no complication such as incision ulceration, exudation, bone nonunion, infection recurrence, or infection in the bone harvesting area. Bone healing time ranged from 16 to 37 weeks, with an average of 24.2 weeks. WBC, ESR, CRP, PCT, and elbow flexion, extension, and total range of motions significantly improved at last follow-up (P<0.05). According to Mayo elbow scoring system, the results were excellent in 14 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 89.47%. ConclusionLimited internal fixation combined with a hinged external fixator in the treatment of the peri-elbow bone infection can effectively control infection and restore the function of the elbow joint.
ObjectiveTo investigate the effectiveness of total elbow arthroplasty (TEA) with preservation of triceps brachii insertion approach.MethodsBetween January 2012 and September 2017, 17 patients with elbow disease were treated with TEA with preservation of triceps brachii insertion approach. There were 3 males and 14 females, with an average age of 65.2 years (range, 48-85 years). The injuries located on left elbow in 5 cases and on right elbow in 12 cases. There were 11 cases of distal humerus fracture (AO type C1 in 2 cases and type C3 in 9 cases); the interval between fracture and operation was 3-10 days (mean, 4.1 days). There were 3 cases of osteoarthritis and 3 cases of rheumatoid arthritis, with the disease duration of 2-26 years (mean, 8.7 years). The postoperative elbow function and pain was assessed by Mayo elbow performance score (MEPS) and visual analogue scale (VAS) score, respectively. The prosthesis position, heterotopic ossification, and periprosthetic fracture were observed by X-ray films.ResultsAll incisions healed by first intention. Sixteen patients were followed up 18-69 months (mean, 40.6 months). Intraoperative ulnar nerve injury occurred in 2 cases, and healed after symptomatic treatment. At last follow-up, the MEPS score was 55-100 (mean, 90.3). The results were excellent in 11 cases, good in 2 cases, fair in 2 cases, and poor in 1 case, with an excellent and good rate of 81.3%. The VAS score was 0-2 (mean, 0.4). X-ray reexamination showed that no polyethylene wear, prosthesis loosening and fracture, abnormal prosthesis position, periprosthetic fracture occurred during the follow-up period, and the prosthesis survival rate was 100%. Heterotopic ossification occurred in 2 and 3 months after operation in 2 cases, respectively.ConclusionThe triceps on approach for TEA are satisfactory for distal humerus fracture, osteoarthritis, and rheumatoid arthritis.
Objective To analyze the effectiveness of binocular loupe assisted mini-lateral and medial incisions in lateral position for the release of elbow stiffness. Methods The clinical data of 16 patients with elbow stiffness treated with binocular loupe assisted mini-internal and external incisions in lateral position release between January 2021 and December 2022 were retrospectively analyzed. There were 9 males and 7 females, aged from 19 to 57 years, with a median age of 33.5 years. Etiologies included olecranon fracture in 6 cases, elbow dislocation in 4 cases, medial epicondyle fracture in 2 cases, radial head fracture in 4 cases, terrible triad of elbow joint in 2 cases, supracondylar fracture of humerus in 1 case, coronoid process fracture of ulna in 1 case, and humerus fracture in 1 case, with 5 cases presenting a combination of two etiologies. The duration of symptoms ranged from 5 to 60 months, with a median of 8 months. Preoperatively, 12 cases had concomitant ulnar nerve numbness, and 6 cases exhibited ectopic ossification. The preoperative range of motion for elbow flexion and extension was (58.63±22.30)°, the visual analogue scale (VAS) score was 4.3±1.6, and the Mayo score was 71.9±7.5. Incision lengths for both lateral and medial approaches were recorded, as well as the occurrence of complications. Clinical outcomes were evaluated using Mayo scores, VAS scores, and elbow range of motion both preoperatively and postoperatively. Results The lateral incision lengths for all patients ranged from 3.0 to 4.8 cm, with an average of 4.1 cm. The medial incision lengths ranged from 2.4 to 4.2 cm, with an average of 3.0 cm. The follow-up duration ranged from 6 to 19 months and a mean of 9.2 months. At last follow-up, 1 patient reported moderate elbow joint pain, and 3 cases exhibited residual mild ulnar nerve numbness. The other patients had no complications such as new heterotopic ossification and ulnar nerve paralysis, which hindered the movement of elbow joint. At last follow-up, the elbow range of motion was (130.44±9.75)°, the VAS score was 1.1±1.0, and the Mayo score was 99.1±3.8, which significantly improved when compared to the preoperative ones (t=−12.418, P<0.001; t=6.419, P<0.001; t=−13.330, P<0.001). ConclusionThe binocular loupe assisted mini-lateral and medial incisions in lateral position integrated the advantages of traditional open and arthroscopic technique, which demonstrated satisfying safety and effectivity for the release of elbow contracture, but it is not indicated for patients with posterior medial heterolateral heterotopic ossification.
ObjectivesTo systematically review the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) on tennis elbow.MethodsPubMed, EMbase, The Cochrane Library, VIP, CNKI and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on NSAIDs for tennis elbow from inception to May 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 8 RCTs involving 595 patients were included. The results of meta-analysis showed that there were no significant differences in the therapeutic effect between NSAIDs and the placebo group (RR=1.10, 95%CI 0.89 to 1.35, P=0.39) or non-placebo control group (RR=0.88, 95%CI 0.77 to 1.00, P=0.06). Compared with non-placebo control group, NSAIDs group had lower VAS score difference (MD=−1.41, 95%CI −2.28 to −0.53, P=0.002).ConclusionsCurrent evidence shows that the effect of NSAIDs on tennis elbow is still uncertain. The improvement of symptoms with NSAIDs may be superior to placebo, but inferior to other treatment methods. Due to the limited quantity and quality of included studies, the above conclusions are required to be verified by more high-quality studies.
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.
OBJECTIVE: To explore the importance of the posterior and lateral arterial network of elbow in the application of the super-regional and mutual-pedicled axial flap. METHODS: Twenty-seven upper extremities of adult cadavers were prepared as casts of Acrylomintril Batradiene Styrene(ABS) resin and corroded in a b solution of NaOH according to natural layers of human tissue. The source, site and structure of the posterior and lateral arterial network of elbow were observed, the number and total sectional area of anastomosing branches crossing the line between two humeral epicondyles were measured and compared with the medial and anterior region. RESULTS: There are 8.64 +/- 2.74(36.42%) and 8.30 +/- 1.19(35.0%) anastomosing branches crossing the posterior and lateral regions, and total section areas are (0.48 +/- 0.11) mm2 and (0.37 +/- 0.03) mm2 respectively. So there is very rich arterial network around the elbow. CONCLUSION: The enough number of anastomosing branches and their section areas of the posterior and lateral region of the elbow make it possible to connect super-regional and mutual-pedicled axial flaps crossing the elbow.
【Abstract】 Objective To research the method and effectiveness of V-Y advancement of skin flap pedicled with the upper limb lateral branch in the treatment of small skin defect in the dorsal elbow. Methods Between March 2008 and August 2010, 6 cases of skin defect in the dorsal elbow were treated by V-Y advancement of skin flap pedicled with the upper limb lateral branch, including 4 males and 2 females with a mean age of 53 years (range, 16-76 years). Defects were caused by crushing in 3 cases, by punching in 2 cases, and the disease duration was 4 hours 30 minutes to 7 days (mean, 29.5 hours); and by chronic infection in 1 case, and the disease duration was 12 months. The defect size ranged from 4.0 cm × 2.5 cm to 9.5 cm × 3.5 cm, all complicating by bone or tendon exposure. The flap size ranged from 6.0 cm × 4.0 cm to 12.5 cm × 9.5 cm; the donor sites were sutured directly. Results All flaps survived completely, wounds and incisions at donor sites healed by first intention. Six cases were followed up 6-12 months after operation. The flaps had good texture and color. Two-point discrimination of the skin flap was 12-16 mm. The function of limb was normal, and elbow flexion and extension activity averaged 105° (range, 95-125°). Conclusion It is ideal to treat small skin defect in the dorsal elbow with V-Y advancement of skin flap pedicled with the upper limb lateral branch because of easier operation and less injury at donor site.
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.
Objective To explore the effectiveness of arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release in the treatment of non-traumatic elbow stiffness. MethodsThe clinical data of 15 patients with non-traumatic elbow stiffness treated with arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release between April 2019 and September 2023 were retrospectively analyzed. There were 6 males and 9 females with an average age of 46 years ranging from 34 to 56 years. The causes included rheumatoid arthritis in 3 cases, gouty arthritis in 2 cases, loose bodies in 3 cases, and elbow osteoarthritis in 7 cases. There were 4 cases with ulnar neuritis and 3 cases with synovial osteochondromatosis. The duration of elbow stiffness ranged from 6 to 18 months, with an average of 10 months. The operation time and intraoperative blood loss were recorded. The effectiveness was evaluated by visual analogue scale (VAS) score, range of elbow motion (maximum flexion, maximum extension, and total flexion and extension), Mayo score, and Hospital for Special Surgery (HSS) elbow score. ResultsThe operation time was 60-90 minutes, with an average of 65 minutes, and the intraoperative blood loss was 40-100 mL, with an average of 62 mL. All patients were followed up 13-18 months, with an average of 14 months. There was no complication such as vascular and nerve injury, poor wound healing, collateral ligament injury, elbow joint space narrowing, osteophyte proliferation, or loose body formation around the joint. At last follow-up, the elbow range of motion (maximum flexion, maximum extension, and total flexion and extension), VAS score, and Mayo score significantly improved when compared with those before operation (P<0.05). The HSS elbow score was 85-95, with an average of 92; 12 cases were excellent, 3 cases were good, and the excellent and good rate was 100%. ConclusionArthroscopic release of elbow joint assisted by medial small incision ulnar nerve release is an effective way to treat non-traumatic elbow stiffness, which has the advantages of small trauma, short operation time, and good effectiveness. It can carry out early elbow rehabilitation training and significantly improve elbow function.
ObjectiveTo evaluate the effectiveness of internal fixation with headless compression hollow embedding screws in the treatment of intraarticular fracture of elbow.MethodsBetween March 2012 and September 2018, 12 patients with intraarticular fracture of elbow were treated with internal fixation with headless compression hollow embedding screws. There were 7 males and 5 females with an average age of 50.3 years (range, 22-65 years). Cause of injury included falling in 7 cases, falling from high places in 4 cases, and traffic accident in 1 case. Ten patients were distal humerus fractures which were classified as type 13-B3 in 8 cases and type 13-C3 in 2 cases according to the International Association of Internal Fixation Research (AO/ASIF). Two patients were radial head fractures which were classified as type Ⅲ according to the modified Mason classifications. The preoperative visual analogue scale (VAS) score was 8.25±0.83. The time from injury to operation was 3-5 days (mean, 3.7 days).ResultsAll incisions healed by first intention. All 12 patients were followed up 6-15 months, with an average of 8.4 months. The results of X-ray films and CT examination showed that the fracture ends were anatomic reduction, and the fractures healed at 6-11 months after operation, with an average of 7.8 months. One patient had heterotopic ossification at 4 months after operation. The VAS scores were 5.17±0.79 at 2 weeks after operation and 0.50±0.50 at last follow-up. There were significant differences between the time points (P<0.05). At last follow-up, the Mayo elbow function score was 68-95, with an average of 83.9. The activity of elbow joint recovered.ConclusionThe intraarticular fracture of elbow can be firmly fixed by the headless compression hollow embedding screw, which can allow the early functional training of the elbow joint, reduce the incidence of heterotopic ossification, and obtain good effectiveness.
