Objective To discuss the role of the bone suture anchors for repair of avulsed deep radioulnar ligaments in maintaining the rotatory stability of the distal radioulnar joint. Methods Nine upper limbs specimens were selected from fresh adult cadavers to make wrist joint-bone capsular ligaments complex specimen. All the specimens were tested under conditions of intact (normal group), deep radioulnar ligaments injury (injury group), and deep radioulnar ligaments injury repaired with anchoring (repair group). The internal and external rotation torque values were recorded in 45° wrist extension, neutral position, and 45° wrist flexion by AG-IS series MS biomechanical testing system. The statistic software was used to compare difference in rotation torque between groups. Results In 45° wrist extension, neutral position, and 45° wrist flexion, the internal rotation torque values in normal group were (0.83±0.33), (0.86±0.34), and (0.36±0.30) N·m respectively; the external rotation torque values were (0.86±0.38), (0.44±0.22), and (0.25±0.21) N·m respectively. The internal rotation torque values in injury group were (0.18±0.17), (0.22±0.17), and (0.16±0.15) N·m respectively; the external rotation torque values were (0.27±0.26), (0.13±0.17), and (0.04±0.04) N·m respectively. The internal rotation torque values in repair group were (0.79±0.34), (0.73±0.33), and (0.41±0.23) N·m respectively; the external rotation torque values were (0.80±0.39), (0.41±0.22), (0.41±0.40) N·m respectively. In 45° wrist extension, neutral position, and 45° wrist flexion, the internal and external rotation torque values in injury group were significantly lower than those in normal group and repair group (P<0.05), but no significant difference was found between repair group and normal group (P>0.05). Conclusion The deep radioulnar ligaments are important structure for maintaining rotatory stability of distal radioulnar joint. Bone anchoring of the avulsed deep radioulnar ligaments to the ulna fovea is critically important in reconstructing function anatomy of the distal radioulnar joint.
ObjectiveTo explore the causes and management of the complications in diabetic foot treated with tibial transverse transport (TTT). MethodsBetween September 2015 and September 2019, 196 patients with diabetic foot were treated with TTT. There were 109 males and 87 females, with an average age of 67.6 years (range, 45-86 years). According to Wagner’s classification, there were 124 cases of grade 3, 62 cases of grade 4, and 10 cases of grade 5; the course of disease was 1-12 months, with an average of 2.6 months. All patients underwent the minimally invasive tibial osteotomy. The osteotomy site was the middle and lower tibia in 62 cases and the middle and upper tibia in 134 cases. The area of osteotomy was 20 cm2 in 83 cases and 7.5 cm2 in 113 cases. The osteotomy block was moved back and forth once in 92 cases and twice in 104 cases. The complications were recorded, including secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection. ResultsAmong 196 patients, 41 cases (20.9%) had complications. Nine cases (4.6%) had secondary fracture at tibial osteotomy, among which 6 cases (9.6%) of middle and lower segment osteotomies and 3 cases (2.2%) of middle and upper segment osteotomies. The incidence between the patients with different osteotomy sites was significant (χ2=5.354, P=0.021). The area of osteotomy was 20 cm2 in 5 cases (6.0%) and 7.5 cm2 in 4 cases (3.5%). There was no significant difference in the incidence between patients with different areas (χ2=0.457, P=0.499). Skin necrosis occurred in the osteotomy area in 12 cases (6.1%), all of which were moved back and forth once. There was a significant difference in the incidence between patients who were treated with transport once and twice (P=0.001). There were 18 cases (9.1%) with pin tract infection, including 12 cases (6.1%) with mild infection and 6 cases (3.0%) with severe infection. There was no significant difference in the incidence between the patients with mild and severe infections (P=0.107).ConclusionTTT is an effective method to treat diabetic foot, but there are complications such as secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection during transport. Preoperative evaluation of indication, standardization of osteotomy mode, size and position of osteotomy block, establishment of individualized removal plan, and strengthening of pin track nursing after operation can effectively reduce complications.
Objective To evaluate the results of open arthrolysis by elevated the lateral and medial collateral l igament-musculature complex from the supracondylar ridge of the humerus in treatment of post-traumatic elbow stiffness. Methods From March 2003 to December 2007, 33 patients with post-traumatic elbow stiffness were treated with open arthrolysis by elevated the lateral and medial collateral l igament-musculature complex from the supracondylar ridge of the humerus. There were 23 males and 10 females, aged 17-70 years old (mean 41.8 years old). According to Morrey, 15 caseswere extremely serious (less than 30° extension-flexion arc) and 18 cases were serious (30-60° extension-flexion arc). The range of motion of the elbow stiffness was (32.5 ± 28.9)° and the Mayo score was 51.9±13.1 before operation. All initial fractures were healed according to cl inical examination and X-rays films. All patients present with a post-traumatic elbow stiffness and the average period from initial trauma to elbow arthrolysis was 16.9 months (2-72 months). Results Wound infection occurred in 1 patient and cured after dressing change and anti-infectious treatment. The wounds healed by first intension in 32 cases. No patient showed sign of elbow instabil ity and debil itating pain. All patients were followed up 6 months to 5 years (mean 3.3 years). At last follow up, the Mayo score was 82.3 ± 14.4 and the range of motion of elbow stiffness was (108.8 ± 36.0)°; showing significant differences when compared with preoperation (P lt; 0.05). According to Mayo evaluation, the results were excellent in 11 cases, good in 18 cases, fair in 2 cases, and poor in 2 cases, the excellent and good rate was 87.88%. Thirty-one patients achieve satisfactory results. Two patients were not satisfied with the result, but the satisfactory results were achieved by a second arthrol ysis. Conclusion Open elbow arthrolysis and postoperative rehabil itation for patients with elbow stiffness can improve joint function and ensure the stabil ity of elbows.

Methods From May 2007 to November 2010, 15 type 2 diabetic patients with distal tibia fractures including 9 males and 6 females were treated with minimally invasive percutaneous plate osteosynthesis. Their age ranged from 38 to 70 years old averaging at 60. Left distal tibia fracture occurred to 4 cases, and right distal tibia fracture occurred to 11 cases. Ten patients had single fracture, and 5 had multiple fractures. According to AO fracture classification, there were two cases of A1, one cases of A2, five cases of A3, three cases of B1 and B3 respectively, and two cases of C1. The time from the occurrence of fracture to operation was ranged from 2 to 14 days. Results The patients were followed up for 8 to 12 months with an average period of ten months. The average operation time was 89 minutes and perioperative blood loss was (285±38) mL. Johner-Wruhs method was used to evaluate the efficacy. Four cases were excellent, 5 were good, 3 were fair, and 3 were poor, with an overall satisfaction rate of 80%. X-ray showed that 13 patients were healed. The healing time was 4 to 8 months, averaging 6 months, and no further fractures occurred. There were 3 cases of urinary tract infection and 1 case of respiratory infection with an infection rate of 26.7%. Conclusion Minimally invasive percutaneous plate osteosynthesis technique for fractures of distal tibia in diabetic patients is a safe method with better mechanical stability, less intervention of blood supply, less soft tissue complications and smaller incisions.
