We performed ulnar nerve neurolysis and transposition during reconstructive operations on 20 consecutive patients (21 elbows) with neuropathy after the failure of primary treatment of elbow fractures. There were 11 men and nine women with a mean age of 48.3 years. Preoperatively, four elbows were in McGowan stage I, seven in stage II and ten in stage III and the mean Gabel and Amadio ulnar nerve score was 3.2. At a mean follow-up of 32.1 months (24 to 67) we performed comprehensive neurological, functional, electrophysiological and outcome assessments. Patient satisfaction was high with good pain relief and restoration of hand strength and dexterity. The mean Gabel and Amadio score had improved to 6.5, an improvement of 3.3. There were one excellent, 16 good, 2 fair and 2 poor results; both of the last were due to failure of the underlying elbow reconstruction. Even for advanced stage-II and stage-III lesions we achieved good function, return of intrinsic power, and a high rate of patient satisfaction

Aims

This study reports the outcomes of a technique of soft-tissue coverage and Chopart amputation for severe crush injuries of the forefoot.

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

We have studied 35 patients with infected reconstructions after segmental resection for bone tumours. Two different regimes of treatment were employed both of which entailed debridement and the use of cement impregnated with antibiotic. In 25 patients gentamicin-PMMA beads were used and in ten an antibiotic-impregnated cement spacer. Better results were achieved with the second procedure in terms of cases healed, the number of operations, time of healing, time of recovery and the functional score. The use of vancomycin in the cement spacer gave better local control

A review is presented of 41 patients with traumatic tetraplegia on whom reconstructive surgery of the upper limb was carried out. Twelve patients were followed up for more than 10 years after operation and the average period overall was seven and a half years. Tendon transfers were made with the aim of providing extension of the elbow or restoring a useful grasp or a combination of both. The assessment was carried out on four main aspects: the function of the elbow, the function of the hand, the ability to carry out the activities of daily living and the effect of the surgical reconstruction on the personal and social achievement of the patient

We have reviewed 30 patients at a mean of 36 months after free vascularised fibular transfer to reconstruct massive skeletal defects after resection of primary bone tumours. There were 23 malignant and 7 benign neoplasms, half in the lower limb and half in the upper. Arthrodesis was performed in 15 and intercalary bone replacement in 15. The mean fibular graft length was 189 mm. Union was achieved in 27 (90%) at an average of 7.6 months, and the 3-year survival was 89%. There was a high complication rate (50%), but most resolved without greatly influencing the final outcome. There was local recurrence in two (6.7%), but 16 of the 24 assessed patients (67%) had satisfactory functional results. This is a reasonably effective means of reconstruction for limb salvage after resection of tumours

We studied bone-tendon healing using immunohistochemical methods in a rabbit model. Reconstruction of the anterior cruciate ligament was undertaken using semitendinosus tendon in 20 rabbits. Immunohistochemical evaluations were performed at one, two, four and eight weeks after the operation. The expression of CD31, RAM-11, VEGF, b-FGF, S-100 protein and collagen I, II and III in the bone-tendon interface was very similar to that in the endochondral ossification. Some of the type-III collagen in the outer layer of the graft, which was deposited at a very early phase after the operation, was believed to have matured into Sharpey-like fibres. However, remodelling of the tendon grafted into the bone tunnel was significantly delayed when compared with this ossification process. To promote healing, we believe that it is necessary to accelerate remodelling of the tendon, simultaneously with the augmentation of the ossification

We reviewed 32 ankles in 30 patients at an average of five years after a Watson-Jones tenodesis. All but one patient had had ankle pain before operation and 19 had had clicking, catching, or locking of the ankle. Eleven of these had an ankle arthrotomy at the time of ligament reconstruction for intraarticular pathology. At review seven of 23 ankles had a significant decrease in ankle motion, and five in subtalar motion, but only two were unstable on examination. Twenty-one ankles, however, caused some pain on activity and nine were tender on palpation. These findings indicate intra-articular degeneration or injury rather than simple instability. Radiographs of 16 ankles showed good varus and anterior-drawer stability. Seven had talocrural osteoarthritis, but only four showed grade-1 subtalar osteoarthritis. We found no correlation between follow-up time and long-term results. The Watson-Jones tenodesis provides good rotational and lateral ankle instability and does not appear to lead to subtalar degeneration

We describe the use of intramedullary reconstruction nails in the treatment of 14 patients with pathological subtrochanteric fractures and coexisting metastases in the femoral shaft. After nailing, all patients were free from pain and regained mobility. They were followed up clinically and radiologically until death from the primary disease. There were no mechanical failures even when a less than ideal reduction had been achieved

The lateral substitution reconstruction operation described by MacIntosh has been evaluated in 27 patients with chronic anterior cruciate ligament deficiency of the knee. The results, at an average of 11.3 years after operation, have been assessed by a scoring system which allocates a maximum of 25 points each for function and for clinical evaluation. Emphasis was placed on subjective giving way and objective evidence of a positive anterior drawer sign and a positive lateral pivot shift test. A score of 46 to 50 was classified as excellent, 41 to 46 as fair, and less than 41 was a poor result: 52% scored excellent, 26% fair and 22% were poor. Most of those with poor results had had evidence of osteoarthritis at the time of operation. Despite the recorded scores, no less than 75% of the patients at long-term follow-up were subjectively improved, and able to maintain an active life style

Aims

Varus-valgus constrained (VVC) implants are often used during revision total knee arthroplasty (TKA) to gain coronal plane stability. However, the increased mechanical torque applied to the bone-cement interface theoretically increases the risk of aseptic loosening. We assessed mid-term survivorship, complications, and clinical outcomes of a fixed-bearing VVC device in revision TKAs.

Aims

We present our experience of using a metal-backed prosthesis and autologous bone graft to treat gross glenoid bone deficiency.

We have described a method of anatomical reconstruction of the lateral ligaments of the ankles with instability using allogeneic fascia lata dried with solvents and sterilised with gamma irradiation. Twenty ankles of 20 patients were assessed objectively and subjectively after a mean follow-up of 4.2 years (3.1 to 10). The result was excellent in 12 (60%), good in seven (35%) and fair in one (5%); none had a poor result. Stress radiography showed that the angle of talar tilt improved from 12.3 ± 4.2° (mean ±. sd. ) to 5.9 ± 3.0° and that the anterior drawer distance decreased from 9.2 ± 3.9 mm to 4.4 ± 2.5 mm. Neither infection nor limitation of movement occurred after operation. Fascia lata allografts provide a good alternative to autogenous grafts such as the peroneus brevis tendon

We examined the association of graft type with the risk of early revision of primary anterior cruciate ligament reconstruction (ACLR) in a community-based sample. A retrospective analysis of a cohort of 9817 ACLRs recorded in an ACLR Registry was performed. Patients were included if they underwent primary ACLR with bone–patellar tendon–bone autograft, hamstring tendon autograft or allograft tissue. Aseptic failure was the main endpoint of the study. After adjusting for age, gender, ethnicity, and body mass index, allografts had a 3.02 times (95% confidence interval (CI) 1.93 to 4.72) higher risk of aseptic revision than bone–patellar tendon–bone autografts (p < 0.001). Hamstring tendon autografts had a 1.82 times (95% CI 1.10 to 3.00) higher risk of revision compared with bone–patellar tendon–bone autografts (p = 0.019). For each year increase in age, the risk of revision decreased by 7% (95% CI 5 to 9). In gender-specific analyses a 2.26 times (95% CI 1.15 to 4.44) increased risk of hamstring tendon autograft revision in females was observed compared with bone–patellar tendon–bone autograft. We conclude that allograft tissue, hamstring tendon autografts, and younger age may all increase the risk of early revision surgery after ACLR.

Aims

To examine the rates of hamstring graft salvage with arthroscopic debridement of infected anterior cruciate ligament (ACL) reconstruction as reported in the literature and discuss functional outcomes.

Our purpose was to determine whether continuous passive motion enhanced the quality of knee ligament reconstruction using carbon fibre. In 46 rabbits the medial collateral ligaments were excised and replaced with carbon fibre prostheses. The animals were treated postoperatively by either continuous passive motion, cast immobilisation or cage activity, termed intermittent active motion. At six weeks, the ligaments were compared histologically and biomechanically with normal (control) medial collateral ligaments and with sham-operated controls. The ligaments treated with continuous passive motion were superior to those in the other two treatment groups. There were no ligament failures in any of the groups. This study suggests that continuous passive motion, initiated immediately postoperatively, enhances the biomechanical properties of carbon fibre ligament replacement of the medial collateral ligament while preventing the harmful effects of joint immobilisation

Anterior cruciate ligament (ACL) reconstruction is commonly performed and has been for many years. Despite this, the technical details related to ACL anatomy, such as tunnel placement, are still a topic for debate. In this paper, we introduce the flat ribbon concept of the anatomy of the ACL, and its relevance to clinical practice.

This review summarises the technique of impaction grafting with mesh augmentation for the treatment of uncontained acetabular defects in revision hip arthroplasty.

The ideal acetabular revision should restore bone stock, use a small socket in the near-anatomic position, and provide durable fixation. Impaction bone grafting, which has been in use for over 40 years, offers the ability to achieve these goals in uncontained defects. The precepts of modern, revision impaction grafting are that the segmental or cavitary defects must be supported with a mesh; the contained cavity is filled with vigorously impacted morselised fresh-frozen allograft; and finally, acrylic cement is used to stabilise the graft and provide rigid, long-lasting fixation of the revised acetabular component.

Favourable results have been published with this technique. While having its limitations, it is a viable option to address large acetabular defects in revision arthroplasty.

A soft-tissue defect over an infected total knee replacement (TKR) presents a difficult technical problem that can be treated with a gastrocnemius flap, which is rotated over the defect during the first-stage of a revision procedure. This facilitates wound healing and the safe introduction of a prosthesis at the second stage. We describe the outcome at a mean follow-up of 4.5 years (1 to 10) in 24 patients with an infected TKR who underwent this procedure. A total of 22 (92%) eventually obtained a satisfactory result. The mean Knee Society score improved from 53 pre-operatively to 103 at the latest follow-up (p < 0.001). The mean Western Ontario and McMaster Universities osteoarthritis index and Short-Form 12 score also improved significantly (p < 0.001).

This form of treatment can be used reliably and safely to treat many of these complex cases where control of infection, retention of the components and acceptable functional recovery are the primary goals.
