Implantless patellar fixation in medial patellofemoral ligament reconstruction / 中华创伤杂志(英文版)

PURPOSE@#The medial patellofemoral ligament (MPFL) acts as primary restraint to lateral patellar dislocation and its rupture has been reported in almost all cases of acute patellar dislocation. Various surgical techniques have been described for MPFL reconstruction, using many femoral and patellar fixation techniques and different grafts. This article details our technique for MPFL reconstruction using semitendinosus graft which avoids the use of implant at patellar end.@*METHODS@#Twenty patients (8 males and 12 females) with complaints regarding acute and chronic lateral patellar instability were evaluated and treated by MPFL reconstruction procedure. The mean age of patients was 21 years (range 17-34 years). MPFL reconstruction was performed using semitendinosus graft passing through two parallel, obliquely directed tunnels created in patella. Fixation of graft was done with an interference screw only at the femoral end. Mean follow-up period after intervention was 26.4 months (range 23-30 months). Results were evaluated using Kujala score.@*RESULTS@#All patients gained adequate patellar stability and full arc of motion. No incidence of patella fracture was noted. There were no postoperative complications related to the procedure. There was no recurrence of instability in patella at final follow-up.@*CONCLUSION@#Passing the graft through the tunnels in patella without use of any implant has given excellent functional outcome and moreover has the advantages of less implant-related complications and cost-effectiveness.

To evaluate the role of platelet-rich plasma in healing of acute diaphyseal fractures of the femur / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>New research is focusing on the use of autologous growth factors to increase the effect of bone fracture healing while decreasing the amount of healing time for the patient. Platelets have been demonstrated to be the natural storage vessel for several growth factors and cytokines that promote blood coagulation, tissue repair, and the process of bone mineralization. The present study aims to evaluate the role of platelet-rich plasma (PRP) in healing of acute femoral shaft fractures radiologically. We hypothesize that it provides artificial hematoma and releases various growth factors.</p><p><b>METHODS</b>This prospective randomized study was carried out in 72 patients of traumatic fracture of the femoral shaft operated with interlocking nails (closed or open). Patients were divided into two groups: study group A (n = 33) treated with intramedullary nailing & PRP injection/gel application in the same setting; and control group B (n = 39) treated with intramedullary nailing without PRP application. Both groups were further divided into two subgroups. Study group included subgroup A1 (n = 14) operated with closed intramedullary nailing and PRP injection at the fracture site under radiological control, and subgroup A2 (n = 19) operated with open intramedullary nailing and PRP gel along with fibrin membrane application at the fracture site; while control group included subgroup B1 (n = 16) operated with closed intramedullary nailing, and subgroup B2 (n = 23) operated with open intramedullary nailing. Radiological assessment of fracture healing was done by measuring the cortex to callus ratio every month till union at 6 months.</p><p><b>RESULTS</b>Measurements of mean cortex to callus ratio revealed significant difference between the groups A & B at third and fourth months. Measurements of mean cortex to callus ratio did not reveal significant difference between the subgroups at first and sixth months. A statistically significant difference was observed between subgroups A1 & B2 and B1 & B2 at the second month; between subgroups A1 & B2, A2 & B2 and B1 & B2 at the third month; and between subgroups A1 & B2 at fourth and fifth months.</p><p><b>CONCLUSION</b>PRP has no effect on femoral shaft fracture healing treated with closed intramedullary nailing. However, PRP and matrix scaffold provided by fibrin membrane may provide an artificial hematoma effect in the initial phase of healing in open or failed closed intramedullary nailing.</p>

Osteosynthesis with long volar locking plates for metaphyseal-diaphyseal fractures of the distal radius / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>Metaphyseal-diaphyseal fractures of the distal radius are a major treatment dilemma and orthopaedic surgeons have to pay due consideration to restoration of anatomy of distal radius together with rotation of the radial shaft and maintenance of radial bow and interosseous space. We performed this study to evaluate the clinic-radiological outcome of metaphyseal-diaphyseal fractures of the distal radius treated with long volar locking plates.</p><p><b>METHODS</b>This prospective study involved 27 patients (22 males and 5 females) with metaphyseal-diaphyseal fracture of the distal radius. Their mean age was (30.12+/-11.48) years (range 19-52 years) and the follow-up was 26.8 months (range 22-34 months). All patients underwent open reduction and internal fixation with a long volar locking plate. According to AO/OTA classification, there were 7 type A3, 13 type C2 and 7 type C3 fractures. Subjective assessment was done based on the disabilities of the arm, shoulder and hand (DASH) questionnaire. Functional evaluation was done by measuring grip strength and range of motion around the wrist and the radiological determinants included radial angle, radial length, volar angle and ulnar variance. The final assessment was done according to Gartland and Werley scoring system.</p><p><b>RESULTS</b>Postoperative radiological parameters were well maintained throughout the trial, and there was significant improvement in the functional parameters from 6 weeks to final follow-up. The average DASH scores improved from 37.5 at 6 weeks to 4.2 at final follow-up. Final assessment using Gartland and Werley scoring system revealed 66.67% (n equal to 18) excellent and 33.33% (n equal to 9) good results. There was one case of superficial infection which responded to antibiotics and another carpel tunnel syndrome which was managed conservatively.</p><p><b>CONCLUSION</b>Volar locking plate fixation for metaphyseal-diaphyseal fractures of distal radius is associated with excellent to good functional outcome, early rehabilitation and minimal complications.</p>

Combined radial and median nerve injury in diaphyseal fracture of humerus: a case report / 中华创伤杂志(英文版)

Radial nerve palsy is the most common neurological involvement in humeral shaft fractures. But combined radial and median nerve injury in a closed diaphyseal fracture of the humerus is rare. Combined injury to both radial and median nerve can cause significant disability. A detailed clinical examination is therefore necessary following humeral shaft fractures. We report a patient with closed diaphyseal humeral fracture (AO 12A-2.3) together with radial and median nerve palsy, its management and review of the literature. As the patient had two nerves involved, surgical exploration was planned. Fracture was reduced and fixed with a 4.5 mm narrow dynamic compression plate. There was no external injury to both radial and median nerves on surgical exploration. Neurological recovery started at 3 weeks' follow-up. Complete recovery was seen at 12 weeks. Careful clinical examination is of the utmost importance in early diagnosis of combined nerve injuries, which allows better management and rehabilitation of the patient.

Pseudoarthrosis of medial tibial plateau fracture----role of alignment procedure / 中华创伤杂志(英文版)

Nonunion in tibial plateau fractures is very rare. Limited literature is available on Pubmed search on intraarticular tibial nonunion. Most of the cases reported have been following failed surgical treatment and none was neglected fractures. Three patients of isolated and neglected medial tibial plateau nonunion with almost similar demographic profile are reported in this paper. All the three patients were managed by minimally invasive compression fixation using lag screws supplemented with limb realignment procedure of high tibial osteotomy. We discussed the injury mechanism, management and rehabilitation in such cases and reviewed the available literature regarding such a presentation.
