Objective To explore the effectiveness of transverse double “8”-shaped tension band technique in the treatment of Lawrence zoneⅠfracture of the 5th metatarsal base. Methods Between February 2019 and October 2021, 15 patients with Lawrence zoneⅠfracture of the 5th metatarsal base were treated with transverse double “8”-shaped tension band technique. There were 8 males and 7 females, with a median age of 40 years (range, 23-59 years). The fractures were caused by sprains. The time from injury to operation was 3-7 days (mean, 4.1 days). X-ray films were taken to observe the fracture healing and the anchor looseness and detachment. The foot function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, and the eversion angle of the calcaneal talus joint. Results The incisions healed by first intention after operation in 14 cases and the incision healed poorly in 1 case. All patients were followed up 8-12 months (median, 10 months). The imaging examination showed that all fractures healed well, with a healing time of 10-14 weeks (mean, 11.7 weeks). At last follow-up, AOFAS score was 82-100 (median, 98); 13 cases were excellent and 2 cases were good, with an excellent and good rate of 100%. VAS score was 0-3 (median, 1). Three cases had mild limited ankle joint range of motion, while 12 cases had normal range of motion. The eversion angle of the calcaneal talus joint was 25°-32° (median, 30°). Conclusion The application of transverse double “8”-shaped tension band technique for Lawrence zone Ⅰ fracture of the 5th metatarsal base has advantages such as simple operation, avoidance of secondary operation, and reduction of foreign body sensation, with definite effectiveness.
ObjectiveTo assess the outcomes in indirect reduction technique via Nice knot for transverse patellar fractures.MethodsThe clinical data of 25 patients with transverse patellar fractures meeting the inclusion criteria between January 2017 and December 2018 were retrospectively analyzed. The patients were divided into trial group (n=13) and control group (n=12) according to different intraoperative reduction methods. No significant difference was found in gender, age, affected side, cause of fracture, classification, or the time from injury to operation between the two groups (P>0.05). In the trial group, No.2 suture was used to cross the quadriceps tendon and patellar tendon to construct the Nice knot, then the suture was tightened to make the distal and proximal fracture segments contact in an indirect reduction pattern. Depend on Nice knot’s sliding compression and self-stabilizing function, the suture mesh created an anterior tension band as a temporary fixation. In the control group, Weber’s clamp was used to hold the fracture segments directly and fixed temporarily. After reduction, terminal fixation was conducted using a titanium Kirschner wire with titanium cable in both groups. The operation time, intraoperative blood loss, follow-up time, fracture healing time, and complications were recorded and compared in the two groups. At last follow-up, the knee function was evaluated according to the Böstman scoring criteria for efficacy in patellar fractures.ResultsThe operation time in the trial group was significantly shorter than that in the control group (t=−2.165, P=0.041). There was no significant difference of intraoperative blood loss between the two groups (t=0.514, P=0.612). The incisions of the two groups healed by first intention. All the patients were followed up 12-16 months, with an average of 14.4 months, no significant difference was found in the follow-up time between the two groups (t=−0.309, P=0.760). One patient in the control group developed soft tissue irritation symptoms at 1 day after operation, and no special treatment was given, the symptoms disappeared at 2 months after operation. The fractures of the two groups healed at the 12-week follow-up. During the follow-up, there was no complication such as loosening and fracture of titanium cables and tendon tissue calcification. At last follow-up, the Böstman score presented no significant difference between the two groups (t=−0.086, P=0.932). In the trial group, an 80-year-old female patient was evaluated as good (score, 27) due to atrophy of the quadriceps femoris, leg weakness, and affected stair climbing, and the rest 24 patients were all evaluated as excellent.ConclusionThe indirect reduction with Nice knot can shorten the operation time in the treatment of transverse patellar fractures, and obtain good effectiveness.

Objective To review the efficacy of reconstruction plate combined with tension band wiring for treating proximal ulna and olecranon fractures. Methods Between November 2004 and September 2009, 10 patients with proximal ulna and olecranon fractures were treated by reconstruction plate combined with tension band wiring. There were 6 males and4 females with an average age of 45.3 years (range, 21-75 years). Five fractures were caused by traffic accident, 2 by fall ing from height, 2 by tumbl ing, and 1 by a machine strangulation. The locations were the left side and the right side in 5 cases respectively. One case was open fracture (Gustilo II) and the other 9 were closed fractures. Olecranon fractures included 4 cases of traverse fractures and 6 cases of comminuted fractures, and proximal ulna fractures included 6 cases of comminuted fractures and 4 cases of obl ique fractures. The combined fractures included 6 radial head fractures, 4 coronoid process fractures, 2 proximal humerus fractures, and 3 scapula fractures; other injury included 1 elbow dislocation and 1 shoulder dislocation. Two patients had secondary operation; the other 8 patients received the primary operations and the time from injury to operation varied from 7 days to 20 days, with an average of 11 days. Results One case had infection at the incision 1 week after operation, and recovered after 2 months of antibiotics and debridement; incisions healed by first intention in other 9 patients. All patients were followed up 12-64 months (mean, 40.5 months). The X-ray films showed that fracture heal ing was achieved at 10-24 weeks (mean, 12 weeks). There was no ulnar nerve symptom in all cases. Heterotopic ossification occurred in 1 case at 2 months and stiffness of the elbow in 1 case at 3 months after operation; they were both cured after symptomatic treatment. Proximal migration of Kirschner wires was found in 1 case at 6 months after operation, whose implants were taken out at 9 months after the first operation because fracture had healed. At last follow-up, the flexion and extension arc of the elbow averaged 92.8°(range, 23-130°), and the arc of forearm rotation averaged 124.4° (range, 42-175°). According to the American Hospital for Special Surgery (HSS) evaluation method, the results were classified as excellent in 6 cases, good in 2, fair in 1, and poor in 1. Conclusion Treating proximal ulna and olecranon fractures by reconstruction plate combined with tension band wiring allows patients to do postoperative exercise early and could effectively avoid compl ications.

Objective To investigate the effectiveness of three-needle and two-cable structure in the treatment of inferior patellar pole avulsion fractures. Methods A clinical data of 62 patients with inferior patellar pole avulsion fractures who were admitted between January 2023 and December 2023 and met the selection criteria was retrospectively analyzed. Among them, the fractures were fixed with three-needle and two-cable structure in 32 patients (observation group) and traditional steel wire tension band in 30 cases (control group). There was no significant difference in the baseline data of age, gender, side of the affected limb, cause of injury, and disease duration between the two groups (P>0.05). The operation time, fracture healing and healing time, patellar height (Insall-Salvati index), occurrence of complications, knee range of motion, and Böstman score at last follow-up were compared between the two groups. Results The operation time of the observation group was significantly shorter than that of the control group (P<0.05). Patients in both groups were followed up 6-12 months (mean, 10.4 months). X-ray films re-examination showed that all fractures healed, and the fracture healing time was significantly shorter in observation group than in control group (P<0.05); no significant difference was found in Insall-Salvati index between the two groups (P>0.05). During follow-up, the complications occurred in 2 cases (6.25%) of observation group and in 9 cases (30.00%) of control group, and the difference in the incidences between the two groups was significant (P<0.05). At last follow-up, the range of motion and Böstman score of the knee joint in observation group were significantly superior to control group (P<0.05). Conclusion Compared with the traditional steel wire tension band fixation, the three-needle and two-cable structure fixation of the inferior patellar pole avulsion fractures is firm, which allows the knee joint to move early after operation and is conducive to the recovery of knee joint function.
