Introduction. Multiple ACL revisions represent an extremely demanding surgery, due to the presence of enlarged or malpositioned tunnels, hardware, injuries to the secondary stabilizers and difficulties in retrieving autologous tendons. An anatomical ACL reconstruction is not always possible. We analyzed the results in a series of patients operated with over the top reconstruction (OTTR) and lateral extra-articular plasty to the Gerdy's tubercle (LP) using Achilles (AT) or tibialis posterior tendon (TPT) allografts. Methods. From 2002 to 2008, twenty-four male athletes with a mean age of 30.8 years were operated. 20 of the patients had two, while four patients had three previous reconstructions. IKDC score and KT evaluation were used at a mean 3.3 years follow-up (2–7 years). Results. The mean IKDC subjective score at follow-up was 81.3. The IKDC objective score rated A or B in 84% of the patients. Of the 20 good results, 17 patients resumed sport activity at the pre-injury level. KT side-to-side difference averaged 3.5 mm in the TPT, versus 3.2 mm in the AT group. No significant differences were noted between the AT and TPT group. Conclusions. Multiple ACL revision surgery is a
Failed fusions are difficult to treat. This is an analysis of a subgroup of 19 patients who received lumbar disc prostheses in a segment adjacent to previous posterolateral instrumented fusions. Out of 142 patients who received 181 lumbar disc replacements of two different models, 19 patients (11 men and eight women) had previously undergone posterolateral fusions of one or two lumbar segments. Seven of these patients had junctional replacement using a Charité disc prosthesis and 12 using a Centurion disc prosthesis. The mean age was 46 years (33 to 63). All patients had a significant flat back deformity of their lumbar spine before the index operation. All presented with sacro-iliac joint pain and 17 had spinal stenosis symptoms. The mean postoperative hospital stay was 3.4 days (2 to 8). All patients returned to their previous occupations at a mean of 29 days (21 to 42). Follow up ranges from 6 to 32 months. At the latest follow-up, 10 patients were very satisfied and nine were satisfied. The Oswestry score in the last 12 (Centurion) patients decreased from 49 ± 12 preoperatively to 16 ±22 at the latest follow-up. There are no published data on this particular subgroup of patients. They are difficult to treat and would otherwise require combined front and back procedures with extension of the fusion in order to correct the sagittal imbalance. Disc replacement seems to be a good
Introduction. Ankle fusion presents a difficult problem in the presence of infection, inadequate soft tissue, poor bone stock and deformity. Nonunion and infection remains a problem even with internal fixation. Ilizarov frame provides an elegant solution to the problem with stable remote fixation while allowing lengthening, deformity correction and weight bearing. Patients and methods. Twenty-one consecutive patients were studied. The mean age at onset of disease was 52 years (range 4-70). Mean duration of the problem was 59.9 months (6-372). Aetiology included traumatic arthritis in 5, traumatic arthritis with osteomyelitis in 1, failed ankle fusion in 8, septic arthritis in 1, infected ankle fracture nonunion in 1, avascular necrosis of talus in 1, congenital deformity in 3 and failed ankle arthroplasty in 1. 15 patients had deformity of the ankle at the time of presentation. 15 of the 21 patients had either clinical or radiological evidence of infection. Treatment principles involved local excision, deformity correction with good alignment and soft tissue management. Static Compression was achieved with an Ilizarov frame while dynamic fixation was performed in 3 cases for lengthening. Antibiotics treatment was continued until union in the infected cases. On achieving union the frame was removed and a below knee cast was applied for 4 weeks. Results. Fusion was achieved in all cases at an average time of 5 months. One patient had below knee amputation for chronic pain. There was no recurrence of infection. Complications included pin site infection, lateral impingement, drug reaction and hind-foot pain. The results were assessed in terms of SF36 and Modified foot and ankle score. Conclusion. The Ilizarov ankle fusion is a reliable
A subgroup of nine patients, five women and four men, who received lumbar disc prostheses in a segment adjacent to previous posterolateral instrumented fusions (one or two levels) is reviewed. Two patients underwent double-level disc replacement. The mean age was 46.1 years (33 to 62). All patients had marked flattening of the lumbar spine before the operation. One patient developed subsidence within two weeks of the procedure but went on to a satisfactory result. One patient with a double-level disc replacement needed another operation because of a missed far out lateral disc. On day five after the procedure, the top-level disc was removed, the level properly decompressed and the disc reinserted, with good results. The mean postoperative hospital stay was 3.9 days (3 to 8). Within a mean time of 32 days (21 to 42), all patients returned to their previous occupations. Follow-up ranged from 3 to 19 months. At the latest follow-up, four of the patients were satisfied and five were very satisfied. Disc replacement seems an ideal
Introduction: Femoroacetabular Impingement (FAI) with more or less subtle abnormality of the hip anatomy and function may contribute to the early development of osteoarthritis (OA). Surgical dislocation as well as arthroscopy of the hip joint are effective and save tools to correct these anatomic deformities. Good clinical results could be achieved predominantly in patients not exceeding grade I OA. The aim of the presented study was to evaluate the clinical and radiological outcome of patients that were treated by open surgical hip dislocation for more advanced OA of the hip joint (>
grade I). Patients and Methods: This is a prospective clinical trial on the outcome of patients after surgical hip dislocation. We report on 45 hip joints (41 patients, 16 m, 25 f) that were treated in our institution by offset-correction (removal of osseous bumps at the femoral head-neck junction) and/or labral surgery for FAI. All patients were evaluated prospectively before and after surgery (Harris Hip Score, radiographic parameters, arthro-MRI). Results: The mean follow up (FU) was 45 months (range: 12–102 months). 9 hips underwent total hip replacement in the further course of FU for persisting pain. In the remaining hips a significant pain reduction but no amelioration of hip range of motion could be accomplished. In 90% of the cases, a good correlation between preop-erative arthro-MRT findings and intraoperative labrum and cartilage assessment could be demonstrated. Concerning the outcome, no patient or radiographic factors could be identified that were strongly associated with failure after surgical dislocation. Discussion and Conclusion: Our data suggests that even patients with more advanced osteoarthritis of the hip may benefit from the surgical dislocation approach as a hip
The treatment of large bony defects following osteomyelitis and trauma with skin damage is challenging. This paper reports the results of fibular transplant for tibial defects. Between 1990 and 2000, five children aged four to nine years were treated. Four had pyogenic osteomyelitis and one a compound fracture with bone loss. All had large wounds on the medial aspect of the tibia. Before reconstruction, conservative treatment lasted five to six months. Sequestrectomy and debridement were performed before fibular transfer. At surgery the fibula was divided below the physis and transferred to the remaining tibia, deep to the tibialis anterior muscle belly. In two cases the fibula was fixed to the lateral aspect of the tibia with screws, and in three into the metaphysis with K-wires. Bone graft was packed around the transfer. Immobilised in a cast for four to six months, the leg was later protected with a calliper. Follow-up ranged from 9 months to 10 years. All children are ambulant, four with callipers and one independently. The latter shows evidence of tibialisation of the fibula. Follow-up continues and the remaining four transfers show solid union and signs of fibular hypertrophy. Osteomyelitis remains a crippling condition that results in bone defects. Fibular transfer is a
Failed internal fixation of hip fracture is a problem with varied aetiology. This becomes more complex when associated with infection. Total hip arthroplasty (THA) remains the only option to restore hip biomechanics when there is partial/complete head destruction associated with it. A retrospective review was performed for 22 consecutive patients of THA following failed infected internal fixation between Sept. 2001 and Nov. 2007. There were 11 dynamic hip screw failures for intertrochanteric fractures, 6 failed osteotomies following proximal femoral fractures, and 5 failed screw fixations for transcervical fractures. The average age of the patients were 48.5years and average follow up period was 3.5 years (5months – 7.5years). All the patients have undergone two stage revision surgeries. The average Harris Hip Score improved from 35.5 to 82.8 at the latest follow up. None of the patients had recurrence of infection. One patient developed sciatic nerve palsy, recovered partially at 1 year following surgery. The results were comparable to primary arthroplasty in femoral neck fractures. THA is a useful

Introduction and Aims: We present the preliminary results of patellar tendon shortening (PTS), for severe crouch gait in children with spastic cerebral palsy who were household ambulators. Method: We performed bilateral patellar tendon shortening in 15 patients with severe spastic diplegia between May 1996 and January 2002. The majority had acquired crouch gait because of isolated lengthening of the Achilles tendons in childhood and presented with anterior knee pain and rapidly deteriorating gait and function. The PTS procedure included dividing the patellar tendon in its mid portion, and performing an overlapping repair by suturing the distal tendon to the distal pole of the patella and the proximal segment to the tibial tubercle. The corrected position of the patella was maintained by a K-wire passed transversely through the patella and incorporated into a cylinder plaster, with the knee in extension, for a period of six weeks. Correction of knee flexion deformity was achieved by transfer of semitendonosis to the distal femur or extension osteotomy of the distal femur. Results: Rehabilitation was predictably slow but all patients regained their pre-operative mobility status within one year and the majority surpassed their pre-operative functional level by two years after surgery. There were no tendon ruptures or growth disturbance in the proximal tibia. Average age at the time of surgery was 14.2 years (10–19 years). Mean follow-up was 27 months (12–48 months). Pre- and post-operative Insall index in 17 knees was 0.68cm (0.46 to 1.07cm, SD=0.16cm) and 0.85cm (0.56 to 1.08cm, SD=0.20) respectively (p<
0.001 Students-t test). Pre-operatively, only three sides had a normal index, but post-operatively 14 sides had a normal index. Crouch gait improved in all patients who were reclassified as community ambulators. Thirteen patients still needed crutches. One patient continued to complain of bilateral knee pain 12 months after surgery, had insufficient correction according to the Insall index (0.58cm on the left 0.56cm on the right). Conclusion: Severe crouch gait after appropriate surgical and orthotic management, maybe due to patella alta, quadriceps and ankle plantarflexors insufficiency. We present preliminary results of a
Background.
As there are many reports describing avascular reactions to metal debris (ARMD) after Metal-on-Metal Hip Arthroplasty (MoMHA), the use of MoMHA, especially hip resurfacing, is decreasing worldwide. In cases of ARMD or a rise of metal ion blood levels, revision is commended even in pain free patients with a well integrated implant. The revision of a well integrated implant will cause bone loss. As most of the patients with a hip resurfacing are young and a good bone stock is desirable for further revision surgeries, the purpose of this study was to evaluate the stability of a cemented polyethylene cup in a metal hip resurfacing cup. Two different hip resurfacing systems were investigated in this study (ASR™, DePuy Orthopaedics, Leatherhead, UK; Cormet™, Corin Group, Cirencester, UK). Six different groups were formed according to the treatment and preparation of the cement-cup-interface (table 1). Before instilling cement in groups 1, 3, 5 the surface, which was contaminated with blood, was cleaned just using a gauze bandage. In groups 2, 4, 6 saline, polyhexanid and a gauze were used to clean the surface prior to the cement application. In group one and two the polyethylene cup (PE) was cemented either into Cormet™ or ASR™, just the ASR™ was further investigated in group three to six. A monoaxial load was applied while the cup was fixed with 45 degrees inclination (group 1–4) and 90 degrees inclination (group 5, 6: rotatory stability) and the failure torque was measured. In contrast to group 1 and 2, the cement penetrated the peripheral groove of the ASR™ in groups 3–6. The mean failure torque of five tests for each group was compared between the groups and the implants. The ASR™ showed mean failure torque of 0.1 Nm in group one, of 0.14 Nm in group two, of 56.9 Nm in group three, of 61.5 Nm in group four, of 2.96 Nm in group five and of 3.04 Nm in group six. The mean failure torque of the Cormet™ was 0.14 Nm both in groups one and two (table 2). In groups 1–6 there were no significant differences between the different preparations of the interface. Furthermore, in groups 1 and 2 there were no significant differences between the Cormet™ and the ASR™. The mean failure torque of group 4 was significant increased compared to group 3 (p=0.008). We saw an early failure of the cement fixation due to the smooth surface of the Cormet™ and the ASR™ components in groups 1, 2, 5, 6. In contrast to other hip resurfacing cups the ASR™ has a peripheral groove, which was not cemented except in groups 3 and 4 and therefore the lever-out failure torque was significant increased in these groups. Nevertheless, the groove did not provide stability of the cement-PE compound in case of rotatory movements. In conclusion we do not recommend the use of these methods in clinical routine. The complete removal of hip resurfacing components seems to be the most reasonable procedure.
We describe the technique of wedge resection for revision of an amputation stump, and report the results of this at below-knee level in 57 patients with peripheral vascular disease; healing occurred in 42 of these (74%).
We reviewed 13 patients with infected nonunion of the distal femur and bone loss, who had been treated by radical surgical debridement and the application of an Ilizarov external fixator. All had severely restricted movement of the knee and a mean of 3.1 previous operations. The mean length of the bony defect was 8.3 cm and no patient was able to bear weight. The mean external fixation time was 309.8 days. According to Paley’s grading system, eight patients had an excellent clinical and radiological result and seven excellent and good functional results. Bony union, the ability to bear weight fully, and resolution of the infection were achieved in all the patients. The external fixation time was increased when the definitive treatment started six months or more after the initial trauma, the patient had been subjected to more than four previous operations and the initial operation had been open reduction and internal fixation.
The purpose of this study is to present the surgical and functional results of a partial and total calcanectomy procedure as a foot salvage alternative in patients with extensive chronic osteomyelitis of the calcaneus.
