Prospective data on 6905 consecutive hip fracture
patients at a district general hospital were analysed to identify the
risk factors for the development of deep infection post-operatively.
The main outcome measure was infection beneath the fascia lata. A total of 50 patients (0.7%) had deep infection. Operations
by consultants or a specialist hip fracture surgeon had half the
rate of deep infection compared with junior grades (p = 0.01). Increased
duration of anaesthesia was significantly associated with deep infection
(p = 0.01). The method of fracture fixation was also significant. Intracapsular
fractures treated with a hemiarthroplasty had seven times the rate
of deep infection compared with those treated by internal fixation
(p = 0.001). Extracapsular fractures treated with an extramedullary
device had a deep infection rate of 0.78% compared with 0% for those
treated with intramedullary devices (p = 0.02). The management of hip fracture patients by a specialist hip fracture
surgeon using appropriate fixation could significantly reduce the
rate of deep infection and associated morbidity, along with extended
hospitalisation and associated costs.
Introduction & Aim. The use of All-Poly Tibia has been in practice since the early 1970's. Recently due to the reports on wear and osteolysis in other articulations, this component has generated significant interest. In the current study we aim to report early medium-term results of All-poly Tibial components in elderly (>70 years) patients. Method. Study of 455 cases done between 2005-2020. All the cases were performed by a single surgeon. All-Poly Tibial component implantations were performed using Standard mechanical jigs and the same posterior-stabilized implant was used for all cases. Results. 20 cases were lost to follow-up. 25 patients died due to natural causes. Mean age at index surgery was 74 years (70 - 91 years). Preop KSS average was 47 (31- 62). Post operative at the last follow up was 87 (71- 93). Of the 410 cases there were 8 revisions, 6 for

The purpose of the study was to identify factors that affect the incidence of deep wound infection after hip fracture surgery. Data from a hip fracture database of 7057 consecutively treated patients at a single centre was used to determine the relationship between
Introduction: Some centres in the UK have recently seen a shift away from internal fixation and free tissue transfer (Fix and Flap), towards temporary monolateral external fixation, soft tissue coverage and definitive Ilizarov frame fixation (Flap and Frame). Methods: Patients sustaining open fractures were identified prospectively and followed up beyond frame removal. After open wound debridement a monolateral ex-fix was applied. Soft tissue coverage was then achieved by our plastic surgeons. As the soft tissues settled, the temporary ex-fix was exchanged to an Ilizarov frame for definitive fixation. Open fractures with bone loss were similarly treated, with either acute shortening or bone transport, depending on the extent of bone loss and state of soft tissues. Results: Between July 2002 and June 2004, 21 grade 3 open fractures in 18 patients were treated by Flap and Frame. There were 15 male and 3 female patients, with mean age 36. Segment involved was 19 tibias and 2 femurs. There was associated bone loss (mean 9cm) in 6 fractures. 8 had other associated injuries. Gustilo grade, 3A/3B/3C = 6/13/2. Both 3C fractures required early amputation. Wound closure, 5/6 fractures with bone loss required free tissue transfer (FTT); however only 3/15 fractures without bone loss required FTT to achieve soft tissue cover, most requiring fasciocutaneous flap or split skin graft only. Median time in Ilizarov frame was 160 days for patients without bone loss. For those fractures with bone loss frame time ranged from 180–540 days, with some patients still requiring ongoing Ilizarov treatment. All fractures without bone loss united. At mean 14 month follow up only one fracture of 21 had clinical evidence of
The objective of this study was to determine the effectiveness of screening and successful treatment of methicillin-resistant Staphylococcus aureus (MRSA) colonisation in elective orthopaedic patients on the subsequent risk of developing a surgical site infection (SSI) with MRSA. We screened 5933 elective orthopaedic in-patients for MRSA at pre-operative assessment. Of these, 108 (1.8%) were colonised with MRSA and 90 subsequently underwent surgery. Despite effective eradication therapy, six of these (6.7%) had an SSI within one year of surgery. Among these infections,
Purpose. To identify the incidence and reasons for revision of the Oxford prosthesis (OXF) in New Zealand. Methods. Review and compare UKA and TKA data including patient-generated Oxford scores after operation. Results. 105 surgeons performed 3,624 OXF (66.5% of all UKA). UKA made up 12.8% of all knee arthroplasties. There were 216 OXF revisions and revision rate (RR) of 1.39 per 100 component-years (p100cy); for UKA this was 1.42 p100cy, and for TKA 0.54 p100cy (OXF vs TKA p< 0.0001). The indications for OXF revisions were unexplained pain (38.0%); aseptic loosening (38.0%); bearing dislocation (9.3%) and
The aim was to identify frequency and pattern of early UKR failure in New Zealand. We analysed data from the New Zealand National Joint Register in a 44 month period of 2000–2003. Thirty-five percent of the 1790 registered UKRs were performed in the last 8 months [ie. in 18% of the total time period]. The ratio of UKRs to TKRs performed was 1:6.25. Fifty two revisions meant a failure rate of 2.9% for UKR (n=1790) compared with 1.6% for TKR (n=11243). The most commonly used implants were the Oxford P3 (68% of total with 2.2% revision rate), MG uni (14.6% with 4.6% revision rate) and Preservation (7% with 5.6 revision rate). The most common reasons for revision (n=52) were aseptic loosening (28%), bearing dislocation or impingement (19%), and unexplained pain (13%). The
Acute urinary retention (AUR) is a common complication following arthroplasty of the major joints and may lead to a delayed discharge with financial considerations not to mention the risks of sepsis – in the urinary tract and also rarely but very significantly in the joint itself. Our aim was to study the various factors associated with risk of AUR following arthroplasty. We conducted a retrospective review of all available casenotes of patients undergoing total hip (THR) and knee arthroplasty (TKR) in a consecutive three year period. Variables noted included rate of AUR, catheterisation, urinary tract infection (UTI), urinanalysis, joint sepsis, anaesthetic type, use of patient controlled analgesia, postoperative morphine requirement, alpha blockade, past medical and urological history. 100 patients underwent THR. AUR occurred in 22%.
In five teaching hospitals, seventy-two patients with seventy-three bicondylar tibial plateau fractures were prospectively randomized by envelope to treatment either by AO methods (group A) or ring fixator methods (group B). Outcome measures included clinical and radiographic parameters, &
HSS knee scores. Results: Re-intervention was necessary within six months in ten group A &
seven Group B patients. Forty-three procedures were performed (thirty-three Group A-ten Group B) I&
D 12- 3: STSG 3-0: Quadricepsplasty 1-0; Manipulation 2–4; Muscle flap 2–0; Above knee amputation 1–0; Revision ORIF 5–1; Revision Rings 0–1; Bone graft 2–1; Bead pouch 3-0; Synovectomy 1-0; Sequestrectomy 1-0. More patients had more septic and wound complications resulting in more need for re-intervention following ORIF. Conclusion. For bi-condylar tibial plateau fractures (OTA 41.C) six-month HSS scores are significantly higher after treatment with Ring Fixator methods. Reintervention rates for
We report the clinical and radiological outcome of 86 revisions of cemented hip arthroplasties using JRI-Furlong hydroxyapatite-ceramic-coated acetabular and femoral components. The acetabular component was revised in 62 hips and the femoral component in all hips. The mean follow-up was 12.6 years and no patient was lost to follow-up. The mean age of the patients was 71.2 years. The mean Harris hip and Oxford scores were 82 (59 to 96) and 23.4 (14 to 40), respectively. The mean Charnley modification of the Merle d’Aubigné and Postel score was 5 (3 to 6) for pain, 4.9 (3 to 6) for movement and 4.4 (3 to 6) for mobility. Migration of the acetabular component was seen in two hips and the mean acetabular inclination was 42.6°. The mean linear polyethylene wear was 0.05 mm/year. The mean subsidence of the femoral component was 1.9 mm and stress shielding was seen in 23 (28%) with bony ingrowth in 76 (94%). Heterotopic ossification was seen in 12 hips (15%). There were three re-revisions, two for
Obtaining primary wound healing in total joint arthroplasty (TJA) is essential to a good result. Wound healing disturbances (WHD) can occur and the consequences can be devastating to the patient and to the surgeon. Determination of the host healing capacity can be useful in predicting complications. Cierney and Mader classified patients as Type A: no healing compromises and Type B: systemic or local healing compromise factors present. Local factors include traumatic arthritis with multiple previous incisions, extensive scarring, lymphodema, poor vascular perfusion, and excessive local adipose deposition. Systemic compromising factors include diabetes, rheumatic diseases, renal or liver disease, immunocompromise, steroids, smoking, and poor nutrition. Low serum albumin, total lymphocyte count, and low transferrin increase WHD. In high risk situations the surgeon should encourage positive patient choices such as smoking cessation and nutritional supplementation to modify healing responses. Use of tourniquet in obese patients also increases WHD. Careful planning of incisions, particularly in patients with scarring or multiple previous operations, is productive. Around the knee the vascular viability is better in the medial flap. Thusly, use the most lateral previous incision, do minimal undermining, and handle tissue meticulously. We do all potentially complicated TKA's without tourniquet to enhance blood flow and tissue viability. The use of perioperative anticoagulation will increase wound problems. If wound drainage or healing problems do occur, immediate action is required.

Material and methods:. Fifteen patients sustaining high energy Gustilo 3B injuries of the tibia were treated from 2003 to 2009 with initial debridement followed by application of an external fixation device allowing immediate acute shortening of the bone gap. The bone defects ranged from 3 cm to 5 cm. Wound management was achieved with a vacuum assisted closure device (VAC) until granulation tissue covering the exposed bone made coverage with split skin grafting possible. A delayed progressive lengthening procedure was used to equalize the leg length discrepancy after wound cover was achieved. Results:. The mean age of the 15 patients was 30 years and treatment times varied from 4 to 12 months. All fractures united with acceptable alignment and equalization of the leg length discrepancy. One patient required repeat procedures for a pin site infection by changing a wire. There was no
This paper reports the clinical outcomes and survivorship of a prospective series of Advantim cementless TKR performed at the RAH between 1993 and 2005. There were 210 knees in 176 patients. All procedures were performed or supervised by a single surgeon. All patients were followed up at regular intervals, up to 15 years later, with Knee Society Cinical Rating System and X-Rays. No patients were lost to follow-up. The knee rating improved from a median of 47 to 90. The median range of motion was 0–100. At 11 years the survivorship of the tibial component was 95.5% and femur was 93.7%. There were two major revisions and three minor revisions for polyethelene exchange. There was no
Fresh-frozen allografts from the humerus were used to help to stabilise the spine after anterior decompression for tuberculosis in 47 children with a mean age of 4.2 years (2 to 9). The average angle of the gibbus, before operation, was 53°; at follow-up, two years later, it was 15°. Rejection of the graft or
Purpose of Study. We intended to determine our rates of deep infection and non-union in severe open tibial fractures treated at our institution with Ilizarov frames. Methods. We retrospectively reviewed the case notes and radiographs of sixty consecutive cases of severe (Gustillo-Anderson Grade III) open fractures of the tibia treated in our tertiary referral unit with the ‘Flap and Frame’ technique. This technique involves early aggressive soft tissue and bone debridement and temporary skeletal stabilisation, followed by soft tissue coverage and then, when the soft tissues have settled, definitive skeletal stabilisation with the Ilizarov frame. The primary outcome measures were the presence of deep infection, occurence of union with the index frame, and any requirement for secondary amputation. Results. Mean average age was 43.3 years (range 16–89). None had neurovascular injuries requiring repair, while three quaters required soft tissue coverage procedures. Half of the fractures had significant bone loss following debridement, with a mean average loss of 28.1 mm (range 5–125). Mean followup was 10.3 months. The
We assessed the outcome of patients with Vancouver type B2 and B3 periprosthetic fractures treated with femoral revision using an uncemented extensively porous-coated implant. A retrospective clinical and radiographic assessment of 22 patients with a mean follow-up of 33.7 months was performed. The mean time from the index procedure to fracture was 10.8 years. There were 17 patients with a satisfactory result. Complications in four patients included subsidence in two,
