OBJECTIVE: To evaluate the effect of uncemented total hip arthroplasty(THA) on treatment of traumatic arthritis caused by intramedullary nailing interfixation of intertrochanteric fractures. METHODS: Total of 22 patients treated with THA due to traumatic arthritis caused by intramedullary nailing interfixation of intertrochanteric fractures from January 2012 to January 2017 were studied retrospectively, including 10 males and 12 females with a mean age of (72.5±9.8) years old ranging from 61 to 84 years old. Initial internal fixation method:14 patients were treated with Gamma nails and 8 patients were treated wit PFNA.The time from internal fixation surgery to THA was 10 to 68 months with an average of (32.2±21.3) months.Harris scores of the hip joint before and after surgery were compared, and the position of the prosthesis through postoperative imaging at 3, 6, 12 months and the last follow-up were evaluated. RESULTS: One patient was died due to heart failure 1 year after operation. Two patients was died to advanced tumor 2 years after operation. The other 19 patients were followed up for 36 to 64 months with an average of (48.5±11.9) months. At final follow up, 14 patients regained the ability to walk independently, 4 patients needed support of a cane, 1 patient needed assistance of a walker. No serious complications such as joint dislocation, periprosthetic fracture and deep venous thrombosis occurred during follow-up. There were no signs of loosening and subsidence of the prosthesis at the final follow-up. Mean Harris hip score increased from (29.2±12.9) points preoperatively to (74.2±11.2) points at the final follow up(P<0.05);the score was excellent in 9 patients, good in 7 and fair in 3. CONCLUSION Uncemented total hip arthroplasty for traumatic arthritis after intramedullary nail fixation of femoral intertrochanteric fracture can significantly improve hip function and effectively avoid bone cement implantation syndrome. The medium-term effect is satisfactory.

PURPOSE: Treatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage. There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis (MIPPO) technique and intramedullary interlocking (IMIL) nailing for extra-articular distal tibia fractures. The aim of our study is to compare the functional outcome between the two treatment methods. METHODS: This was the prospective comparative study of 100 patients with distal third tibia fractures divided into two groups. The first group of patients were treated with MIPPO technique while the second group of patients were managed by IMIL nailing. Patients were followed up in outpatient department to assess the functional outcomes, malunion, delayed union, nonunion, superficial and deep infection between the two groups. Statistical analyses were performed using the SPSS software (version 16.0). RESULTS: Average malunion (degrees) in the MIPPO group was 5 (3-7) ± 1.41 vs. 10.22 (8-14) ± 2.04 in the IMIL group (p = 0.001). Similarly postoperative knee pain in the IMIL group was 10% vs. 2% in the MIPPO group (p = 0.001). In terms of superficial infection and nonunion, the results were 8% vs. 4% and 2% vs. 6% for the MIPPO and IMIL group, respectively (p = 0.001). CONCLUSION Both procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue, bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing. Considering the results of the study, we have slightly more preference for the MIPPO technique.

OBJECTIVE: To explore clinical effect of lateral locking compression plate combined with medial buttress plate in treating osteoporotic comminuted fractures of proximal humerus. METHODS: From May 2017 to December 2021, 12 patients with osteoporotic comminution of proximal humerus were treated by lateral locking compression plates combined with medial buttress plates, including 5 males and 7 females, aged from 55 to 78 years old, bone mineral density(BMD) less than -2.5 g/cm3, the time from injury to operation was from 2 to 6 days. According to Neer classification, 7 patients were type Ⅲ, 4 patients were type Ⅳ and 1 patient was type Ⅵ. Postoperative complications, fracture healing and internal fixation were observed and Constant-Murley score of shoulder joint was used to evaluate clinical effects at 6 months after operation. RESULTS: Postoperative wound healed well at stage I. All patients were followed up from 6 to 18 months. Humeral head collapse and necrosis occurred in 1 patient and humeral head varus in 1 patient. No impact of shoulder joint, internal fixation loosening occurred. Constant-Murley score at 6 months ranged from 45 to 90 points, and 6 patients got excellent result, 3 good, and 3 poor. CONCLUSION Locking compression plate combined with medial buttress plate could effectively reconstruct medial humeral column support and enhance fracture stability, and receive satisfactory clinical results. However, no control group was established in this study, and function of shoulder joint has not been evaluated many times after operation, so it cannot dynamically reflect changes of shoulder joint function.

PURPOSETo investigate the early and mid-term results of open reduction and internal fixation (ORIF) with transarticular external fixation (TEF) but no deltoid ligament repair (DLR) in the treatment of supination-external rotation type IV equivalent (SER IV E) ankle fractures (AO/OTA classification 44-B 3.1) and provide evidence for clinical practice.

METHODSThis study cohort consisted of 22 patients with SER IV E ankle fractures that underwent ORIF with TEF but no DLR between December 2011 and December 2014. There were 13 males and 9 females, mean age 38.9 years (range, 17-73 years). Eight cases involved the left side and 14 the right side. The causes of fractures included road traffic accidents (11 cases), falling from height (6 cases) and sports injuries (5 cases). The mean period of hospitalization was 9.8 days (range, 6-14 days). For all the patients, MRI and three-dimensional CT were done before surgery and X-rays done preoperatively and during follow-ups. The external frame was kept for 8-10 weeks. The preoperative American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 56.86 ± 4.400, the Medical Outcomes Short Form 36-item (SF-36) questionnaire score was 57.41 ± 4.102 and the visual analog score (VAS) was 5.50 ± 1.058. Patients' main complaints about inconvenience of daily life were also recorded.

RESULTSAll the 22 patients were followed up for 24-63 months (mean, 33.6 months). None of them developed nonunion during the follow-up; pin site infection was observed in one patient and posttraumatic osteoarthritis in another. At the final follow-up, the average AOFAS score, SF-36 score and VAS score were respectively 90.59 ± 5.096, 79.59 ± 5.394 and 1.82 ± 1.181, which were significantly improved compared with the preoperative data (t = 26.221, p < 0.001; t = 11.910, p < 0.001; t = 11.571, p < 0.001). The therapeutic effect was excellent in 13 cases, good in 7 cases and fair in 2 cases, with a good-excellent rate of 90.9%. Patients' main complaints were inconvenience of clothing (17 cases) and extremity cleaning (5 cases).

CONCLUSIONIn the treatment of SER IV E ankle fractures, ORIF with TEF but no DLR can achieve satisfactory outcome, but long-term effect should be confirmed by large sample randomized controlled trials.

PURPOSETo compare the clinical efficacy and complications of limited internal fixation combined with external fixation (LIFEF) and open reduction and internal fixation (ORIF) in the treatment of Pilon fracture.

METHODSWe searched databases including Pubmed, Embase, Web of science, Cochrane Library and China Biology Medicine disc for the studies comparing clinical efficacy and complications of LIFEF and ORIF in the treatment of Pilon fracture. The clinical efficacy was evaluated by the rate of nonunion, malunion/delayed union and the excellent/good rate assessed by Mazur ankle score. The complications including infections and arthritis symptoms after surgery were also investigated.

RESULTSNine trials including 498 pilon fractures of 494 patients were identified. The meta-analysis found no significant differences in nonunion rate (RR = 1.60, 95% CI: 0.66 to 3.86, p = 0.30), and the excellent/good rate (RR = 0.95, 95% CI: 0.86 to 1.04, p = 0.28) between LIFEF group and ORIF group. For assessment of infections, there were significant differences in the rate of deep infection (RR = 2.18, 95% CI: 1.34 to 3.55, p = 0.002), and the rate of arthritis (RR = 1.26, 95% CI: 1.03 to 1.53, p = 0.02) between LIFEF group and ORIF group.

CONCLUSIONLIFEF has similar effect as ORIF in the treatment of pilon fractures, however, LIFEF group has significantly higher risk of complications than ORIF group does. So LIFEF is not recommended in the treatment of pilon fracture.

Adjacent vertebral fractures are common in patients with osteoporotic vertebral compression fractures (OVCFs) after kyphoplasty. This finite element study was to examine whether short segment pedicle screw fixation (PSF) with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae after kyphoplasty for OVCFs. By simulating cement augmentation with or without short segment pedicle screw fixation (PSF), two tridimensional, anatomically detailed finite element models of the T10-L2 functional spinal junction were developed. The insertion of pedicle screws into the intact vertebra apparently decreased the stress distribution of the treated vertebra in vertical compression and other load situations. The stress distribution in the bone structures of the intact vertebra adjacent to the intact-screwed vertebra was much less than that in the one adjacent to the treated vertebra. The insertion of pedicle screws into the intact vertebra greatly decreased the maximum displacement of the cortical bones and cancellous bones of the vertebrae. Our results indicated that short segment PSF with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae in the management of OVCFs.

PURPOSETo compare the efficacy of percutaneous poking reduction and fixationwith open reduction and fixation in the treatment of displaced calcaneal fractures.

METHODSReports of studies using case-controlled trials (CCT) to compare the percutaneous poking reduction and fixation with the open reduction and fixation in the management of calcaneal fractures were retrieved from the Cochrane Library, PubMed Database, CNKI, Chinese Biomedical Database, Wanfang Data (from January of 2005 to August of 2015). Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software Revman 5.0 was used for data-analysis.

RESULTSFifteen articles were included in the meta-analysis. Comparison of the efficacy of percutaneous poking reduction and fixation with open reduction and fixation in the treatment of calcaneal fractures revealed statistical significance in the incidence of complications after operation [RR = 0.32, 95% CI (0.20, 0.5), p < 0.05]. However, there were neither statistical significance in the degrees of recovery for calcaneal Bohler angle [WMD = -1.65, 95% CI (-3.43, 0.14), p > 0.05] and calcaneal Gissane angle [WMD = -3.21, 95% CI (-6.75, 0.33), p > 0.05], nor statistical significance in the rate of good foot function after operation [RR= 0.95, 95% CI (0.90, 1.00), p > 0.05].

CONCLUSIONFor the treatment of calcaneal fractures, percutaneous poking reduction and fixation is su- perior to open reduction and fixation in terms of the incidence of postoperative complications. But both techniques can obtain satisfactory clinical function.

PURPOSETo describe our clinical experience with a system named SureShot? Distal Targeting (Smith & Nephew, Memphis, USA) based on magnetic field presence and discuss our suggestions on this technique.

METHODSWe analysed prospectively 47 patients affected by humeral, tibial or femoral fractures, treated in our institution during a 3-year period of time (August 2010 to September 2013). We considered the following parameters: the time to set up, the time to position a single screw, the effectiveness of the system (drilling ad screwing), the irradiation exposure time during distal locking procedure and surgical complications.

RESULTSA total number of 96 screws were inserted. The mean preparation time of the device was 5.1 min ± 2 min (range 3-10 min). The mean time for single screw targeting was 5.8 min ± 2.3 min (range 4-18 min). No major complications occurred. Only a few locking procedures were needed to be practiced in order to obtain the required expertise with this targeting device.

CONCLUSIONAccording to our results, this device is reliable and valid whenever the correct technique is followed. It is also user friendly, exposes to lower radiation and needs less surgical time compared to relative data from the literature. However, the surgeon should always be aware of how to use the free hand technique in case of malfunctioning of the system.

PURPOSETo evaluate the efficacy of intramedullary Kirschner wires for the treatment of unstable tibial shaft fractures in children.

METHODSThis prospective study was conducted at the Department of Orthopaedic Surgery in Maharishi Markandeshwar Medical College from June 2005 to June 2010. Sixty-six children having closed fracture of the tibial shaft with a mean age of 7.7 years (range, 2-14 years) were recruited from emergency and outpatient department. They were treated with percutaneous intramedullary Kirschner wires. The clinical results of our study were rated on the basis of the criteria of union, nonunion, delayed union or malunion. All children were followed for one year.

RESULTSChildren achieved union in a mean time of 8 weeks (range, 6-10 weeks). Postoperatively, three children (4.55%) had delayed union, one (1.52%) valgus deformity of lower leg, three (4.55%) post- operative knee pain and twelve (18.18%) skin irritation at pin site.Wires were removed after 8-22 weeks without any complications. No patient was lost to follow-up. The results were excellent in 95.45% and good in 4.55% children.

CONCLUSIONThis technique is cost-effective, simple, quick to perform, safe and reliable and avoids pro- longed hospitalization with good results.
