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 evaluate the effectiveness of open reduction and trans-carpometacarpal joint internal fixation with mini locked-plate for treatment of comminuted fracture of base of the fifth metacarpal. Methods Between July 2015 and December 2017, 8 cases of comminuted fractures of base of the fifth metacarpals were treated with open reduction and trans-carpometacarpal joint internal fixation with mini locked-plate. There were 7 males and 1 female with an age of 19-45 years (mean, 32.5 years). The causes of injury included 2 cases of hitting hard objects while clenching fist, 6 cases of falling injury. There were 2 cases of subluxation of fifth carpal joints and 1 case of dislocation. The time from injury to operation was 1-5 days (mean, 3.5 days). The stability of fracture ends could not be maintained by preoperative evaluation without over articular fixation or short time over articular fixation. Postoperative complications and fracture healing were observed, and hand function was evaluated at last follow-up according to the total active motion (TAM) recommended by the Branch of Hand Surgery of Chinese Medicine Association. Results All the incisions healed by first intention without complications such as wound infection, cutaneous necrosis, tendon or nerve injury. All the patients were followed up 6-18 months (mean, 12 months). All fractures healed with the healing time of 12-16 weeks (mean, 13 weeks). Within 4 months after operation, all patients were able to return to pre-injury job. At last follow-up, according to the TAM recommended by the Branch of Hand Surgery of Chinese Medicine Association, the results were excellent in 7 cases, good in 1 case, with the excellent and good rate of 100%. Conclusion Applying of mini locked-plate for treatment of comminuted fractures of base of the fifth metacarpal, of which cannot obtain stable fixation through non-transarticular or short-time transarticular fixation, can achieve satisfactory functional results with very few complications through trans-carpometacarpal joint approach, thus the procedure can be used as an alternative operation scheme.
Objective To study the clinical outcome of comminuted factures at distal femur and proximal tibia treated with AO less invasive stabilization systems (LISS). Methods The clinical data of 14 cases of distal femoral fracture and proximal tibial fracture from September 2003 to May 2005 were analyzed retrospectively. The injury was caused by traffic accident in 9 cases, by fall in 3 cases and by slipping in 2 cases. Of 14 cases, there were 5 open fractures and 9 close fractures, including 5 cases of distal femoral comminuted fracture and 9 cases of proximal shaft comminuted fractures. According to AO/OTA classification, the fractures were classified as 33C2 in 3 cases，33C3 in 2 cases,41A2 in 2 cases，41A3 in 2 cases，41B2 in 3 cases and 41C2 in 2 cases. All patients were treated by the internal fixation with LISS-distal femur or with LISS-proximal tibia. Healing of wounds, the X-ray films before and after operations, and therecovery of joint function were observed. Results The patients were followed up from 1 month to 20 months (11 months on average). Twelve cases achieved solid osseous unions from 3 months to 5 months postoperativly; 2 cases had a good reduction and recovered smoothly 2-3 months postoperatively. The results were excellent in 10 cases, good in 3 cases and fair in 1 case according to Johner-Wruhs knee scoring. The range of knee flexion-extension was 110-130° in 11 cases, 100° in 2 cases and 80° in 1 case. Conclusion LISS is an effective method of internal fixation for treating comminntedfracture of distal femur or proximal tibia. It has the advantages of less injury, satisfied reduction and reliable fixation.
ObjectiveTo explore a new method of treating serious tibiofibula comminuted fracture by using three-dimensional (3-D) printing personalized external fixator. MethodsIn April 2015, a male patient (aged 18 years with a height of 171 cm and a weight of 67 kg) with left tibiofibula comminuted fracture was included in the study. Computer-assisted reduction technique combined with 3-D printing was used to develop a customised personalized external fixator for fracture reduction. The effectiveness was observed. ResultsThe operation time was about 10 minutes without fluoroscopy, and successful reduction was obtained. The patient had equal limb length after operation. X-ray films showed that the posterior angulation of distal fracture was corrected 37°, and the eversion angle was corrected 4°. The tibial fractures had good paraposition or alignment, and the lower limb force line was corrected completely. No new fracture displacement occurred. The clinical healing time of fracture was 3.5 months and the bone union was achieved after 8 months. The function of affected limb recovered well after operation. ConclusionA personalized external fixator for serious tibiofibula comminuted fracture reduction made by 3-D printing technique has the merits of easy manipulation, high individuation, accurate reduction, stable fixation, and no need of fluoroscopy.
ObjectiveTo explore the effectiveness and operative methods to treat first metatarsal diaphysis comminuted fractures with mini-plate via medial approach. MethodsBetween January 2012 and January 2013, 15 patients with first metatarsal shaft comminuted fractures were treated. There were 11 males and 4 females (6 left feet and 9 right feet) with an average age of 38.6 years (range, 27-56 years). The injury causes included falling injury in 6 cases, crash injury of heavy object in 7 cases, and sprain in 2 cases. The left side was involved in 6 cases and the right side in 9 cases. The time from injury to operation was 8.5 days on average (range, 7-10 days). According to AO classification, all cases were rated as 81(T)-C2 type. The surgical treatments included open reduction and internal fixation with mini-plate by medial approach. ResultsPrimary healing of incision was obtained in all cases, and no infection occurred. Twelve patients were followed up 18 months on average (range, 12-24 months). All fractures healed well, and the mean time of bone union was 11.5 weeks (range, 10-14 weeks). No loosening or breakage of internal fixation was observed. At last follow-up, the patients could walk with full weight-bearing, and had no pain. According to American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale, the mean score was 85.2 (range, 76-96). ConclusionAnatomic reduction and stable internal fixation are important for first metatarsal comminuted fracture, which is the key point for recovery of foot form and foot arch function. And the medial approach could achieve full exposure and improve the cosmetic results.
OBJECTIVE To investigate the effects of sodium hyaluronate in supplementary treatment of comminuted fracture of ankle. METHODS Thirty-seven patients suffered from comminuted fracture of ankle were operated for restoration by routing methods, and received 2 ml of sodium hyaluronate injection intra-articularly before the closure of incision. The ankle was fixed and given the second intra-articular injection on the 3rd day after operation. Then, the patients were given sodium hyaluronate injection intra-articularly at a week intervals till the paste was removed after 4 weeks. All patients were followed up. The clinical results were evaluated by measuring the symptoms of pain, and the function of walking and other daily living activities. RESULTS All the patients were followed up for 6 to 27 months, among them, 30 patients were cured completely without any symptoms, the ankle function for walking and daily living activities was normal, 6 patients felt pain with violent activity or walking exceeding 1 km, one patient suffered from comminuted fracture with compressed depression was not improved due to his ankle being not restored properly. CONCLUSION Intra-articular injection of sodium hyaluronate is an effective supplementary treatment for comminuted fracture of ankle.
