Microfracture is frequently used as the first line of treatment for the repair of traumatic cartilage defects. We present the clinical and histological results 18 months to two-years after treatment in a 26-year-old male with a post-traumatic chondral defect of the medial femoral condyle managed by microfracture covered with chondrotissue, a cell-free cartilage implant made of a resorbable polyglycolic acid felt and hyaluronic acid

Fresh osteochondral allografts were used to repair post-traumatic osteoarticular defects in 92 knees. At the time of grafting, varus or valgus deformities were corrected by upper tibial or supracondylar femoral osteotomies. A survivorship analysis was performed in which failure was defined as the need for a revision operation or the persistence of the pre-operative symptoms. There was a 75% success rate at five years, 64% at ten years and 63% at 14 years. The failure rate was higher for bipolar grafts than for unipolar and the results in patients over the age of 60 years were poor. The outcome did not depend on the sex of the patient and the results of allografts in the medial and lateral compartments of the knee were similar. Careful patient selection, correction of joint malalignment by osteotomy, and rigid fixation of the graft are all mandatory requirements for success. We recommend this method for the treatment of post-traumatic osteochondral defects in the knees of relatively young and active patients

Aims. Cubitus varus is the most common late complication of a supracondylar fracture of the humerus in children. Correction can be performed using one of a number of techniques of osteotomy but each has disadvantages. We describe a new technique for correcting post-traumatic cubitus varus using a lateral closing wedge isosceles triangular osteotomy. Patients and Methods. A lateral closing wedge isosceles triangular osteotomy was performed in 25 patients (15 male and ten female with a mean age of 9.5 years (6 to 12)) between May 2010 and April 2013. All patients had cubitus varus secondary to malunion of a supracondylar fracture, with good function of the elbow and a full range of movement. The osteotomy lines were marked on the bone with an isosceles triangular template made before surgery, after which the osteotomy was performed leaving the medial cortex intact. Fixation was performed using two lateral 2 mm Kirschner (K)-wires and patients were immobilised in an above-elbow plaster. By six to eight weeks callus was present and the wires and cast were removed. Patients were reviewed at four and six weeks, three, six and 12 months and then every two years until skeletal maturity. Clinical and radiographic outcomes were categorised as excellent, good or poor. Results. A total of 23 patients had an excellent and two had a good outcome at a mean final follow-up of 3.4 years (two to four). The mean post-operative carrying angle in the corrected elbow was 11.7° (7° to 18°). One patient fell, displacing the osteotomy, and needed revision of the fixation. No patient had a nerve injury. Conclusion. A lateral isosceles triangular osteotomy and with K-wire fixation is a practical, effective, reliable, safe and simple method of correcting post-traumatic cubitus varus in children. It has inherent stability and excellent cosmesis without prominence of the lateral condyle. . Cite this article: Bone Joint J 2016;98-B:1521–5

Two cases of post-traumatic avascular necrosis of the head of the femur without evident dislocation of the head or fracture of the head or neck are recorded

1. Two cases of recurrent post-traumatic dislocation of the hip are reported. 2. The literature is reviewed and the rarity of the condition is emphasised. Only twenty-two cases have been previously reported, eleven in adults and eleven in children. 3. The sequence of events leading to recurrent dislocation is not understood but the following important facts emerge. The initial incident could not be distinguished from that causing uncomplicated dislocations. There was a significant delay in reduction in a number of cases. Subsequent dislocations followed minor injury. A large defect in the posterior capsule with a large synovial-lined pouch or false joint was found at operation in both our cases. The ligamentum teres was not seen at operation. The surgeon was unable to redislocate the hips during the operation. 4. In both cases reported here treatment was by excision of the posterior pouch and repair of the capsular defect. 5. Based on the above facts some tentative deductions are made

We present the outcome of the treatment of chronic post-traumatic contractures of the proximal interphalangeal joint by gradual distraction correction using an external fixator. A total of 30 consecutive patients with a mean age of 34 years (17 to 54) had distraction for a mean of 16 days (10 to 22). The fixator was removed after a mean of 29 days (16 to 40). Assessment at a mean of 34 months (18 to 54) after completion of treatment showed that the mean active range of movement had significantly increased by 63° (30° to 90°; p < 0.001). The mean active extension gained was 47° (30° to 75°). Patients aged less than 40 years fared slightly better with a mean gain in active range of movement of 65° (30° to 90°) compared with those aged more than 40 years, who had a mean gain in active range of movement of 55° (30° to 70°) but the difference was not statistically significant (p = 0.148). The use of joint distraction to correct chronic flexion contracture of the proximal interphalangeal joint is a minimally-invasive and effective method of treatment

1. Two cases of post-traumatic osteolysis of the outer end of the clavicle are reported. 2. The essential features of the lesion are summarised. 3. The possible medico-legal importance of the condition is mentioned

1 . This case of post-traumatic osteochondritis of the lower tibial epiphysis is important because the condition is rare. 2. The similarity to osteochondritis in other sites dating from a single injury is noted. 3. The ankle joint bears more body weight per surface area of articular cartilage than other weight-bearing joint surfaces. It is of interest that regeneration took place in spite of the fact that the child continued to bear weight and that the joint was immobilised for only two months, beginning four months after the original injury

Seven children with chronic post-traumatic dislocation of the radial head were treated by open reduction and ligament reconstruction by a triceps tendon slip. In the four patients with anterior dislocation, good results were achieved; in the two with anterolateral dislocations bowing of the ulna persisted and subluxation recurred. One patient with an anterior dislocation developed a radio-ulnar synostosis. For anterolateral dislocations, we advise the combining of open reduction and ligament reconstruction with osteotomy of the ulna

1. The dominant role of pathogenic staphylococci in surgical infections has been confirmed by positive isolations in 89·9 per cent of a wide variety of lesions in a hospital infective unit. Of 150 staphylococci isolated, 147 were sensitive to fusidic acid, two were slightly sensitive and only one was resistant. 2. Fusidic acid was administered as sodium fusidate to 100 patients with staphylococcal infections (including seventy-two with chronic post-traumatic osteomyelitis). Sterile swabs were achieved in seventy-seven of these patients and in the remaining twenty-three a change of flora was detected. 3. Bone samples were taken at operation from twenty-nine patients with chronic osteomyelitis who had been treated for at least five days with fusidic acid. Depending on dosage, the mean fusidic acid concentrations were 7·3 and 9·8 micrograms per gram. Corresponding levels in non-inflammatory bone samples from thirty-one patients were, depending on the duration of treatment, 12·3, 2l·3 and 25·4 micrograms per gram. The fusidic acid levels in cancellous bone were almost twice as high as those in compact bone. 4. The relevance of these findings to the use of fusidic acid therapy as an adjunct to surgical management of chronic osteomyelitis is discussed

We performed resection of part of an injured peripheral nerve in 20 patients with post-traumatic neuralgia, after conservative treatment had failed. All had burning pain, paraesthesia and dysaesthesia in the area innervated by the injured nerve. We resected the nerve in the area in which the patient felt pain, and a further 3 cm proximal to the site of injury. In all cases, the local pain disappeared or markedly decreased. The areas of pain relief and of nerve resection coincided completely in 17 patients and partially in three. The results were assessed as excellent by five patients, good by 11, and fair by four. There were no poor results. Histological examination of the resected nerves showed Wallerian degeneration and immunohistochemical tests indicated that substance P, a polypeptide which may contribute to nociceptive transmission, was present in the tissue around the degenerated nerves

We have retrospectively reviewed the clinical and radiological results in 204 consecutive adult patients who had surgical correction of 70 late post-traumatic pelvic nonunions and 134 malalignments. The deformed pelvises were subdivided into united (true), unstable, ununited, and partially stable malalignments with heterotopic bone. The principal complaints were of pain, pelvic instability, sitting imbalance, and apparent limb-length discrepancy. After surgery, 195 patients (96%) achieved a primary union and 144 (71%) had slight, intermittent or no pelvic pain, while pelvic instability was entirely eliminated. Overall, 131 patients (64.2%) were extremely satisfied, 58 (28.4%) were satisfied and 15 (7.4%) were unsatisfied. After reconstruction of the malaligned pelvises, 67 results (50%) were anatomical, 47 (35%) were satisfactory and 20 (15%) were unsatisfactory. For a pelvic nonunion with local osteopenia and malalignment, stabilisation of all three pelvic columns is recommended. True pelvic (united) malunions were the most satisfactorily realigned and had the fewest complications. Ununited and unstable malalignments, especially those with heterotopic bone, had the poorest corrections and the most neurological complications. A therapeutic alternative, by the local resection of a symptomatic bony prominence, and fixation in situ of a posterior pelvic nonunion, gives highly effective symptomatic relief with fewer complications. Despite this, many patients had persistent low back pain

Following the discovery of a powerful venous pump in the foot that is activated by weight-bearing independently of muscular action, a pneumatic impulse device was developed to actuate this pump artificially. In a multicentre international trial the device was shown to reduce post-traumatic and postoperative swelling; pain also was alleviated. Evidence is also presented that dangerously high compartment pressures may be reduced to acceptable levels and fasciotomy avoided. We present an explanation of the clinical effects of activation of the venous footpump, based on recent improved understanding of the physiology of the microcirculation. The hyperaemic response that follows the liberation of endothelial-derived relaxing factor (EDRF) by sudden changes of pressure after weight-bearing or impulse compression is particularly important

Previous studies of the Ilizarov procedure have concentrated on musculoskeletal assessments rather than the opinions of patients. In a prospective trial of 25 consecutive patients, we evaluated the effect of Ilizarov reconstruction of post-traumatic deformity on general health status using the SF36 and Nottingham Health Profile (NHP). The patients had very low preoperative scores, which remained low during treatment and correction, but increased postoperatively. The mean overall SF36 score improved from 36 ± 3 to 58 ± 7 (p = 0.031) and the NHP score from 39 ± 11 to 67 ± 10 (p = 0.002). The improvements in scores were not limited to the physical components and were equal or better than the improvements reported for other orthopaedic procedures, including total joint arthroplasty. Ilizarov-type reconstruction of deformity of the lower limb not only restores bony configuration, but also produces a large improvement in the general health status of patients

1. Sixteen patients with articular cartilage erosions after slight injury have been described, as have the results of their treatment.

2. The clinical features of this rarely diagnosed condition are discussed. Attention is drawn to "articular crepitus" and "synovial crepitus" as useful physical signs in establishing the diagnosis.

3. A radiographic sign of localised subarticular osteoporosis is reported and discussed.

4. The surgical treatment used was either shaving of the affected area of cartilage or a combination of shaving with drilling of the subchondral bone plate.

In 28 patients with a solitary diagnosis of instability of the trapeziometacarpal joint because of a rupture of the anterior oblique ligament, reconstruction was carried out using a slip of the tendon of flexor carpi radialis. We were able to review 26 patients. The results after a follow-up of four years seven months showed that most (87%) had significant relief from pain and symptoms. Seventeen were graded as good to excellent. The mean grip strength recovered to 86% of the contralateral side. Most patients (81%) felt that they had subjective improvement and would have undergone the operation again. A lesser functional result was seen in those who developed a flexion deformity because of overtightening of the reconstruction. Increased awareness of this lesion can lead to an early and clear diagnosis so that the patient may be advised adequately. We describe a specific, diagnostic, clinical test which we have used consistently and successfully.
