ObjectiveTo analyze the clinical efficacy of Ilizarov bone transport and bone lengthening in the treatment of long bone infection and limb shortening, and fracture nonunion caused by infection. MethodsWe retrospectively analyzed the clinical data of 13 patients with long bone infection, chronic osteomyelitis of the femur and tibia, and infectious bone nonunion, treated with infection focus removal, Ilizarov outer fixation, bone transport and bone lengthening between June 2011 and October 2013. Among the patients, 8 of them had chronic osteomyelitis of the femur and tibia, 4 had infectious bone nonunion, and one had chronic fibula osteomyelitis. ResultsAll the 13 patients had a first-stage healing of the sinus tract and junctions. Among the patients who did the bone transport by themselves after being discharged from hospital, two had nail infections (one was cured after debridement, and the other underwent amputation after re-infection after debridement). One had a re-fracture after the healing of the previous fracture, and was cured by intramedullary nailing. The length of bone transport in these 13 cases ranged from 5 to 13 cm, averaging 7.5 cm. After bone transport, 11 patients had equal length of the lower limbs, and the affected lower limb of the other two patients became shorter than before. No neural function damage occurred in all the patients. ConclusionIlizarov bone transport and lengthening technique is an effective way to treat infections and bone defect of long bone, and it can improve patients' quality of life greatly.
ObjectiveTo assess the effect of surgical treatment or conservative treatment on the clinical outcomes for displaced 3-part or 4-part proximal humeral fractures in elderly patients. MethodsWe searched CNKI (between January 1979 and April 2014), Wanfang Data (between January 1982 and April 2014), Medline (between January 1946 and April 2014), PubMed (between January 1966 and April 2014), Embase (between January 1974 and April 2014) and Cochrane Database of Systematic Reviews (between January 2005 and April 2014) for randomized controlled trials comparing surgical treatment and conservative treatment for displaced 3-part or 4-part proximal humeral fractures in elderly patients. The data were extracted and a Meta-analysis was made using RevMan 5.2. ResultsFive randomized controlled trials with a total of 226 patients were accepted in this Meta-analysis. The differences of Constant scores[WMD=0.48, 95%CI (-4.39, 5.35), P=0.85], incidences of avascular necrosisr of the humeral head[RR=0.66, 95%CI (0.37, 1.16), P=0.15], incidences of nonunion[RR=0.56, 95%CI (0.20, 1.58), P=0.27], incidences of osteoarthritis[RR=0.35, 95%CI (0.10, 1.22), P=0.10] between the two groups were not statistically different. The difference of incidences of additional surgery after primary treatment was statistically significant[RR=3.52, 95%CI (1.18, 10.45), P=0.02]. ConclusionThe results does not support the surgical treatment to improve the shoulder function when compared with conservative treatment for treating elderly patients with displaced 3-part or 4-part proximal humeral fractures. But surgical treatment increases the incidence of additional surgery after primary treatment. Considering surgery can increase the trauma and economic burden of patients, so the conservative treatment is suggested.
ObjectiveTo systematically review the effects of associated ulnar styloid fracture on the prognosis of distal radius fracture. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 5 2013), CNKI, CBM and WanFang Data were searched up to May 2013 for collecting cohort studies about the effects of associated ulnar styloid fracture on the prognosis of distal radius fracture. According to the inclusion and exclusion criteria, related cohort studies were screened, data were extracted and cross-checked, and quality of included studies was independently evaluated by two reviewers. Meta-analysis was then conducted using RevMan 5.2 software. ResultsA total of 9 studies involving 1 020 patients were included. The results of meta-analysis showed that there was no significant difference in GartlandWerley score between patients with ulnar styloid fracture or not. Statistical significant difference was found in DASH score between the two groups (MD=2.71, 95% CI 0.26 to 5.16, P=0.03), which indicated that patients with ulnar styloid fracture got higher score in DASH score. ConclusionCurrent evidence shows that ulnar styloid fracture may affect the prognosis of patients with distal radius fracture. Due to the quality and quantity limitation of the included studies, the above conclusion needs to be further verified by more high quality studies in future.
ObjectiveTo analyze the outcome and prognostic factors of using locking plate for treating proximal humerus fracture. MethodsBetween January 2005 and January 2012, 45 aged patients with a displaced 3-part or 4-part fracture of the proximal humerus were treated by locking plate. Range of motion and Constant-Mudey score were observed during the follow-up. ResultsForty-three patients were followed up from 12 to 48 months with an average of 18 months. The mean final Constant-Mudey score was 72.3±9.5 and 6 of them needed a second surgery. In addition to fracture type, other prognostic factors included redisplacement (4 cases, 9.3%), nonunion (3 cases, 7.0%), crashing (3 cases, 7.0%), necrosis of the humeral head (6 cases, 14.0%) and screw cut-out (5 cases, 11.6%). Among the patients with disrupted medial calcar, 4 needed a second surgery at the final follow-up, 3 had redisplacement, 2 had nonunion, and 2 had screw cut-out. ConclusionLocked screw-plates provide more secure fixation of fracture in aged patients, but the complication rate remains high. We suggest anatomic reduction, and plate and screws position, length of the screws, the medial cortical contact and stability may be the chief prognostic factors affecting the shoulder function following a proximal humeral fracture.
