Tendon injury causes significant morbidity during the productive age, and the number is increase in recent decades. Tensile strength is the most important factor in tendon function of style, and the results of repair should be able to withstand large current style of early mobilization. This research was an experimental research design with the post-test only control group design with the subject of the rabbit. A total of 18 research subjects who meet the requirements of the study inclusion were randomly divided into treatment and control groups. Control group was a group of rabbits that were repaired with 4 strand modified Kessler technique after Achilles tendon cut sharply. While the treatment group were a group of rabbits that were repaired with continuous-cores technique. The ratio of collagen I/III in rabbit Achilles tendon repair with the technique of continuous-cores are smaller compared to the control group with value of P <0.05. Also Showed statistical analysis tensile strength of rabbit Achilles tendon repair with the technique of continuous-core is greater than the control group at P <0.05.

Hand injuries which involve substantial skin loss require immediate soft tissue cover to achieve early wound closure and to minimize wound infection and scarring. In 1978, Dr. Yang Guofan and Dr. Chen Baoqui described a flap from the forearm based on the radial artery or Chinese Forearm Flap. A 30-year-old male was admitted to the emergency room because of crush injury. From physical examination we found crush injuries of left hand followed with open wound between 1st and 2nd finger at dorsal and palmar side with muscle, tendon, and bone exposed, with open dislocation left 1st carpometacarpal joint, open fracture dislocation left 1st metacarpophalank joint, open fracture Left Base 2nd, 4th metacarpal, open dislocation 3rd base metacarpal, open fracture left trapezoid, open left trapezium. Soft tissue injuries of the hand which require flap cover pose a problem mainly because of the apparent lack of availability of local tissue. Wound healing problems can result in an impaired functional outcome. For complication, initially, sensory disturbances can be found in 17-75% but decrease during the next months. This radial forearm flap method of post-traumatic thumb reconstruction nowadays doesn’t require expert microsurgical knowledge, which is indispensable in case of replantation or revascularization of the amputated thumb. Correct planning and elevation presupposed the flap success rates average at least 90% with no relevant limitations in strength, motion and hemodynamics in the forearm or hand and non-disturbing sensory and cosmetic outcome at the donor site.

Background: Dislocation of the peroneal tendons is uncommon and is frequently misdiagnosed as an ankle sprain usually in young and active patients. The most common mechanism is a dorsiflexory force on the ankle associated with a rapid and strong contraction of the peroneal tendons and with eversion of the hindfoot, rapid contraction can also lead to injury to the superior peroneal retinaculum.Case Report: We reported a case of traumatic dislocation of the peroneal tendons. The patient was a 32-year-old who complained of right ankle pain and a feeling of dislocation after suffered an accident while playing football.Discussion: There have been many options reported for surgical repair of peroneal subluxation or dislocation. These include direct repair of peroneal retinaculum, reconstruction of peroneal retinaculum, bone block (lateral malleolus, sliding graft), and groove deepening and rerouting procedures.Reconstruction of the peroneal tendon can be accomplished using the peroneus brevis, plantaris, and/or Achilles tendons. Complications associated with these techniques include graft fracture, tendonitis, pain, and re-subluxation.Conclusions: Acute peroneal tendon dislocation is a challenging entity because it may mimic and frequently be misdiagnosed as an ankle sprain. Conservative treatment may be considered for acute dislocation but may be associated with high failure rate. There have been many options reported for surgical repair of peroneal subluxation or dislocation include direct repair of peroneal retinaculum, reconstruction of peroneal retinaculum, bone block (lateral malleolus, sliding graft), and groove deepening and rerouting procedures. Keywords: Peroneal Tendon, Subluxation, Dislocation, Ankle Injury.
