The patients' age, gender, occupation, residence, season, cause of injury, Rüedi-Allg?wer classification, and AO classification were analyzed.Results:A total of 234 inpatients with tibial pilon fracture were collected, including 179 males and 55 females, with a ratio of male to female of 3.3∶ 1. The prevalence age ranged from 41 to 50 years in male patients (31.3%, 56/179) and from 51 to 60 years in female patients (25.5%, 14/55). In the 234 patients, farmers (101 cases, 43.2%), rural area (166 cases, 70.9%) and spring season (77 cases, 32.9%) accounted for a higher proportion. The proportions of high-altitude falling (41.0%, 96/234) and high-energy injury (61.5%, 144/234) were the highest. Of the 234 patients by the Rüedi-Allg?wer classification, 23 (9.8%) had type Ⅰ fracture, 90 (38.5%) type Ⅱ fracture, and 121 (51.7%) type Ⅲ fracture, with type Ⅲ fracture prevalent in males (58.1%, 104/179) and type Ⅱ fracture prevalent in females (16.4%, 9/55). Of the 234 patients by the AO classification, 131 (56.0%) had type 43B fracture and 103 (44.0%) type 43C fracture, with a higher proportion of type 43B fractures in women (67.3%, 37/55) than in men (52.5%, 94/179). In type 43B fractures, type 43B3 (43.5%, 57/131) and type 43B3.3 (75.4%, 43/57) were the most common; in type 43C fractures, type 43C3 (74.8%, 77/103) and type 43C3.3 (51.9%, 40/77) were the most common.Conclusions:In the recent 4 years in The Third Hospital of Hebei Medical University, pilon fractures increased year by year and occurred more frequently in spring. They were more common in farmers and in the rural areas. They prevailed in the patients aged from 41 to 50 years. The Rüedi-Allg?wer type Ⅲ fractures and the AO type 43B fractures were the most common.

Recent advances in mechanism and treatment of fracture-related tension blister / 中华创伤杂志

The presence of tension blister often predicts severe soft tissue damage，which not only increases the risk of wound complications but also prolongs the surgical treatment time. However，the developed tension blister has been proposed as a potential decompressive approach for it may relieve the pressure of osteofascial compartment and improve the likelihood of relieving clinical symptoms，as well as avoid unnecessary surgery in cases of suspected osteofascial compartment syndrome. Recently，the osteofascial system has been increasingly recognized that associations were found between the tension blister and osteofascial self-release processing. Thus，the timing of blister occurrence and regression substantially influences physicians′ clinical decisions，making blister management as part of the treatment of fractures. In this review，the authors give an overview of the characteristics，mechanism，stress reduction effect，prevention，current treatment status and complications of the fracture-related tension blister，hoping to help orthopedic physicians understand and treat the tensile blister.

The bone-hardness distributions of the human middle-upper thoracic vertebrae by micro-indentation / 中华骨科杂志

Objective:To measure and analyze the distribution characteristics of the micro-hardness of the middle-upper thoracic vertebrae (T 1-T 10) in the human body. Methods:T 1-T 10 vertebrae from three fresh cadavers were divided into vertebral body area and attachment area. 3 mm specimens were cut by a high-precision slow saw and 11 regions were selected and measured on each vertebrae by a Vickers microhardness tester (cortical bone: 1-9, cancellous bone: 10-11). The micro-hardness distribution of T 1-T 10 vertebrae was recorded and analyzed. Results:A total of 330 measurement areas from 30 vertebrae were measured, and 1 650 hardness values were collected. The average hardness values of the overall cortical bone of the middle-upper thoracic vertebrae of the 3 cadavers were 30.55±5.44 HV, 29.94±4.86 HV, and 29.55±4.36 HV, respectively. The difference among the groups was statistically significant ( F=4.680, P=0.009). The average hardness values of the overall cancellous bone were 27.93±5.61 HV, 28.21±4.96 HV, 27.98±3.94 HV, respectively. There was no significant difference among the groups ( F=0.091, P=0.913). There were statistically significant differences between the hardness values in the attachment area and vertebral body area of each cadaver ( t=7.467, 4.750, 6.621, P<0.001); the hardness of the cancellous bone in the attachment area of each cadaver was higher than that of the cancellous bone in the vertebral body ( t=1.785, 3.159, 3.103, P=0.077, 0.002, 0.003). The distribution of microhardness in 11 measurement areas of 3 cadavers were similar: the hardness of the cortical bone of pedicle, lamina and inferior endplate cortex (1, 2, 7) were higher; the hardness of the cortical bone of upper endplate and peripheral cortex (6, 8, 9) were lower. The distribution patterns of the microhardness in different vertebral segments of the 3 cadavers were similar: The hardness values gradually increased from T 1 to T 10. The vertebra with the largest hardness of the cortical bone was T 8; and the vertebra with the largest hardness of the cancellous bone were T 7, T 7 and T 6, respectively. Conclusion:The hardness of the upper endplate and peripheral cortex was low, which could disperse the load to protect the fragile cancellous bone. The hardness of the pedicle was the highest. The hardness of the cortical bone was higher than that of the cancellous bone, and the values of different segments gradually increased from top to bottom, which may be related to the physiological and anatomical morphology, and the gradual increase of the load of muscle force and body weight.

Anatomic quadrilateral surface plate for the treatment of both?column acetabular fractures through Stoppa combined with iliac fossa approach / 中华骨科杂志

Objective To explore the clinical outcome an anatomic quadrilateral surface plate for both?column acetabu?lar fractures through the Stoppa combined with iliac fossa approach. Methods A retrospective study of the patients with both?col?umn acetabular fractures treated with an anatomic quadrilateral surface plate through the Stoppa combined with iliac fossa ap?proach from November 2015 to June 2017 was performed. Nineteen patients including 16 males and 3 females met the inclusion criteria. The mean age of included patients was 49.11 years (range, 25-68 years). There were 8 cases of fall injury, 7 cases of car accident injury and 4 cases of crushing injury. There were 11 cases of C1 type injury, 7 cases of C2 type, and 1 case of C3 type ac?cording to Tile classification. Patients included in this study were both?column acetabular fractures according to Letournel?Judet classification. There were six cases associated with posterior wall detachment. Minimally Stoppa combined with iliac fossa ap?proach was performed to manage the displaced fragments. First, the anteromedially displaced iliopubic fragment was managed with a reconstruction plate through iliac fossa approach. Then, the medially displaced ischiadic fragment could be fixed with an anatom?ic quadrilateral surface plate through the Stoppa approach. The reduction quality was assessed by postoperative radiographs and CT scans according to the criteria proposed by Matta. The function of hip joint was assessed by the Merle d’Aubigné?Posteal score modified by Matta. Results The average operation time and blood loss were 115.26 min (range, 90-160 min) and 534.21 ml (range, 300-1000 ml), respectively. The mean length surgical incision was 18.82 cm(range, 16-20 cm). Average follow?up time was 19.84 months (range, 12-28 months). According to Matta criteria of reduction quality, anatomic reduction was obtained in 14 cases, and satisfactory reduction was gained in 3 cases, while unsatisfactory reduction was found in 2 cases (satisfactory rate= 89.47%). All fractures healed well and mean healing time was 3.32 months (range, 3-5 months). The mean Merle d’Aubigné?Post?eal score modified by Matta was 16.95 (range, 13-18), including 12 cases of excellent, 4 cases of good, and 3 cases of fair (satisfac?tory rate=84.21%). Intraoperative injury of lateral femoral cutaneous nerve developed in a case and obturator nerve damage oc?curred in another patient, respectively. Relevant symptoms were totally disappeared after two months’conservative treatment (in?cluding neurotrophic therapy combined with adduction exercise of the affected thigh). Iliac fossa hematoma occurred in a case and relevant symptom was eliminated after puncture. Conclusion Satisfactory clinical outcome of both?column acetabular fractures could be obtained by the anatomic quadrilateral surface plate through the Stoppa combined with iliac fossa approach.

Myofascial self-release law / 中华创伤杂志

Osteofascial compartment syndrome (OFCS) is clinically common and is well known to orthopedic surgeons.Clinicians attach great importance to OFCS because of its severe clinical consequences,and decompression of fascial compartment is often performed in emergency treatment.This article reviews the literature on the threshold of fascial compartment decompression proposed by many scholars in the past and discusses the problems in the clinical diagnosis of acute compartment syndrome,especially the inconsistent pressure thresholds as the indication for emergency decompression surgery.By observing calf fractures patients with tension blister,we found that the pressure of fascia decreased sharply upon the appearance of blisters.Meanwhile,the swelling gradually subsided as well as the clinical manifestations of pain and parasthsia.In view of the uncertainty of various thresholds of fascial decompression and self-decompression,the concepts of myofascial self-release law and muscle-swelling syndrome were first proposed.The author believes that when intracompartmental pressure rises to a point,some unknown mechanisms of fascia can achieve self-decompression.Therefore,no compartment syndrome will take place.We also emphasize that the ' muscle-swelling syndrome'should be strictly distinguished from the soft tissue necrosis caused by crush syndrome and acute limb vascular injury,so as to provide more precise treatment.We believe that without external restrictions such as casts,splints and compression bandages,the muscle-swelling syndrome can achieve self decompression by releasing the pressure in the compartment through tension blisters,and there is no need for fasciotomy.
