We retrospectively reviewed the outcomes of 33
consecutive patients who had undergone an extra-articular, total or
partial scapulectomy for a malignant tumour of the shoulder girdle
between 1 July 2001 and 30 September 2013. Of these, 26 had tumours
which originated in the scapula or the adjacent soft tissue and
underwent a classic Tikhoff–Linberg procedure, while seven with
tumours arising from the proximal humerus were treated with a modified
Tikhoff-Linberg operation. We used a Ligament Advanced Reinforcement
System for soft-tissue reconstruction in nine patients, but not
in the other 24. The mean Musculoskeletal Tumor Society score (MSTS) was 17.6
(95% confidence interval (CI) 15.9 to 19.4); 17.6 (95% CI 15.5 to
19.6) after the classic Tikhoff–Linberg procedure and 18.1 (95%
CI 13.8 to 22.3) after the modified Tikhoff–Linberg procedure. Patients
who had undergone a LARS soft-tissue reconstruction had a mean score
of 18.6 (95% (CI) 13.9 to 22.4) compared with 17.2 (95% CI 15.5
to 19.0) for those who did not. The Tikhoff–Linberg procedure is a useful method for wide resection
of a malignant tumour of the shoulder girdle which helps to preserve
hand and elbow function. The method of soft-tissue reconstruction
has no effect on functional outcome. Cite this article:
The aim of this study was to evaluate the functional
and oncological outcome of extracorporeally irradiated autografts
used to reconstruct the pelvis after a P1/2 internal hemipelvectomy. The study included 18 patients with a primary malignant bone
tumour of the pelvis. There were 13 males and five females with
a mean age of 24.8 years (8 to 62). Of these, seven had an osteogenic
sarcoma, six a Ewing’s sarcoma, and five a chondrosarcoma. At a
mean follow-up of 51.6 months (4 to 185), nine patients had died
with metastatic disease while nine were free from disease. Local
recurrence occurred in three patients all of whom eventually died of
their disease. Deep infection occurred in three patients and required
removal of their graft in two while the third underwent a hindquarter
amputation for extensive flap necrosis. The mean Musculoskeletal Tumor Society functional score of the
16 patients who could be followed-up for at least 12 months was
77% (50 to 90). Those 15 patients who completed the Toronto Extremity
Salvage Score questionnaire had a mean score of 71% (53 to 85). Extracorporeal irradiation and re-implantation of bone is a valid
method of reconstruction after an internal hemipelvectomy. It has
an acceptable morbidity and a functional outcome that compares favourably
with other available reconstructive techniques. Cite this article:
A total of 31 patients, (20 women, 11 men; mean
age 62.5 years old; 23 to 81), who underwent conversion of a Girdlestone
resection-arthroplasty (RA) to a total hip replacement (THR) were
compared with 93 patients, (60 women, 33 men; mean age 63.4 years
old; 20 to 89), who had revision THR surgery for aseptic loosening
in a retrospective matched case-control study. Age, gender and the
extent of the pre-operative bone defect were similar in all patients.
Mean follow-up was 9.3 years (5 to 18). Pre-operative function and range of movement were better in the
control group (p = 0.01 and 0.003, respectively) and pre-operative
leg length discrepancy (LLD) was greater in the RA group (p <
0.001). The post-operative clinical outcome was similar in both
groups except for mean post-operative LLD, which was greater in
the study group (p = 0.003). There was a significant interaction
effect for LLD in the study group (p <
0.001). A two-way analysis
of variance showed that clinical outcome depended on patient age
(patients older than 70 years old had worse pre-operative pain,
p = 0.017) or bone defect (patients with a large acetabular bone
defect had higher LLD, p = 0.006, worse post-operative function
p = 0.009 and range of movement, p = 0.005), irrespective of the
group. Despite major acetabular and femoral bone defects requiring complex
surgical reconstruction techniques, THR after RA shows a clinical
outcome similar to those obtained in aseptic revision surgery for
hips with similar sized bone defects. Cite this article:
We investigated the functional outcome in patients
who underwent reverse shoulder replacement (RSR) after removal of
a tumour of the proximal humerus. A total of 16 patients (ten women
and six men) underwent this procedure between 1998 and 2011 in our
hospital. Five patients died and one was lost to follow-up. Ten
patients were available for review at a mean follow-up of 46 months
(12 to 136). Eight patients had a primary and two patients a secondary
bone tumour. At final follow up the mean range of active movement was: abduction
78° (30° to 150°); flexion 98° (45° to 180°); external rotation
32° (10° to 60°); internal rotation 51° (10° to 80°). The mean Musculoskeletal
Tumor Society score was 77% (60% to 90%) and the mean Toronto Extremity
Salvage Score was 70% (30% to 91%). Two patients had a superficial
infection and one had a deep infection and underwent a two-stage
revision procedure. In two patients there was loosening of the RSR;
one dislocated twice. All patients had some degree of atrophy or
pseudo-atrophy of the deltoid muscle. Use of a RSR in patients with a tumour of the proximal humerus
gives acceptable results. Cite this article:
Between 1988 and 2006, 18 patients had a custom-made endoprosthetic replacement of the distal humerus for bone tumours at our institution. There were 11 primary malignant neoplasms, six secondary deposits, and one benign aggressive tumour. The mean follow-up was for 4.4 years (1 to 18.2). Complications occurred in nine patients and included aseptic loosening in three (16.6%), local recurrence in two (11%), infection in two (11%), neuropraxia of the radial nerve in one (5.5%) and a peri-prosthetic fracture in one (5.5%). Excision was inadequate in four patients (22%), all of which developed local recurrence and/or metastases. There were seven deaths from the primary disease after a mean of 2.3 years (1 to 5), one of whom had an above-elbow amputation for local recurrence seven months before death. The remaining six had satisfactory elbow function at their last follow-up. The 11 living patients were evaluated using the Musculoskeletal Tumour Society and Toronto Extremity Salvage scoring systems. The mean scores achieved were 76% (67% to 87%) and 73% (59% to 79%), respectively. Overall, 17 of 18 patients had significant improvement in the degree of their pain following operation. Custom-made endoprosthetic reconstruction of the elbow for bone tumours is a viable treatment in carefully selected patients. It maintains satisfactory function and provides good pain relief.
Congenital pseudarthrosis of the tibia remains one of the most difficult orthopaedic problems. We describe early excision and the use of the Masquelet technique to reconstruct the bone defect in a child aged 14 months. Consolidation sufficient for complete weight-bearing was achieved by seven weeks. After two and a half years, the child was asymptomatic with a fully reconstructed tibia and no leg-length discrepancy.
"Wedge excision" of the apex of the curve is the rational way of correcting a scoliosis. It is a straightforward procedure which is successful in practice.
We have undertaken a prospective, randomised study to compare conservation of acetabular bone after total hip replacement and resurfacing arthroplasty of the hip. We randomly assigned 210 hips to one of the two treatment groups. Uncemented, press-fit acetabular components were used for both. No significant difference was found in the mean diameter of acetabular implant inserted in the groups (54.74 mm for total hip replacement and 54.90 mm for resurfacing arthroplasty). In seven resurfacing procedures (6.8%), the surgeon used a larger size of component in order to match the corresponding diameter of the femoral component. With resurfacing arthroplasty, conservation of bone is clearly advantageous on the femoral side. Our study has shown that, with a specific design of acetabular implant and by following a careful surgical technique, removal of bone on the acetabular side is comparable with that of total hip replacement.
Endoprosthetic replacement of the distal tibia and ankle joint for a primary bone tumour is a rarely attempted and technically challenging procedure. We report the outcome of six patients treated between 1981 and 2007. There were four males and two females, with a mean age of 43.5 years (15 to 75), and a mean follow-up of 9.6 years (1 to 27). No patient developed a local recurrence or metastasis. Two of the six went on to have a below-knee amputation for persistent infection after a mean 16 months (1 to 31). The four patients who retained their endoprosthesis had a mean musculoskeletal tumour society score of 70% and a mean Toronto extremity salvage score of 71%. All were pain free and able to perform most activities of daily living in comfort. A custom-made endoprosthetic replacement of the distal tibia and ankle joint is a viable treatment option for carefully selected patients with a primary bone tumour. Patients should, however, be informed of the risk of infection and the potential need for amputation if this cannot be controlled.
1. A case of massive osteolysis of the right humerus is described. Diseased bone was resected leaving only the lower part of the humerus. The resected bone was replaced by a titanium prosthesis. 2. The diagnosis, etiology, prognosis and treatment of the condition are briefly discussed.
Seven children underwent partial meniscectomy for symptomatic discoid lateral meniscus. This procedure, modifying the discoid meniscus to the normal semilunar shape, was indicated only when degeneration or tear was minimal, when the meniscus was not abnormally thickened nor of Wrisberg type, when it was not hypermobile, when the capsular attachment was intact, and when the residual meniscus was free from abnormality. The results were excellent clinically, radiologically and arthroscopically, rehabilitation was shortened to half that required for total meniscectomy and the residual meniscus functioned entirely normally.
1. A case of congenital bowing of the tibia is described in which pseudarthrosis developed and recurred after nine operations performed by the age of ten years. 2. Union was finally secured by a procedure based on deep impaction of the trimmed upper fragment into the reamed-out lower fragment. This was followed by a Boyd type of partial amputation of the foot with calcaneo-tibial arthrodesis. 3. The end-bearing stump four years later is entirely satisfactory and the simple prosthesis gives equality of leg lengths.
From the experimental evidence above, it is clear that in the upper four centimetres of the forearm the posterior interosseous nerve moves up to one centimetre or more medially relative to the radius on pronation of the forearm. This movement becomes of importance when considered in relation to methods of operative approach for excision of the radial head. Operative approaches have been described in which emphasis has been placed on the position of incision, but in none of these is there any mention of the position of the forearm. We suggest that the following precautions should be taken. 1) During excision of the radial head the forearm should be kept in full pronation. 2) The incision should be as posterior as possible to ensure that it is well clear of the nerve. 3) With the forearm pronated the incision extends from a little above the lateral epicondyle along the postero-lateral aspect of the forearm for not more than 5 centimetres; proportionately less in a child. 4) The surgical assistant's attention should be brought to the damage that the posterior interosseous nerve might sustain from undue pressure–for instance by retraction, especially by bone levers–in the anterior part of the wound.
Aims. Sagittal plane imbalance (SPI), or asymmetry between extension and flexion gaps, is an important issue in total knee arthroplasty (TKA). The purpose of this study was to compare SPI between kinematic alignment (KA), mechanical alignment (MA), and functional alignment (FA) strategies. Methods. In 137 robotic-assisted TKAs, extension and flexion stressed gap laxities and bone
Aims. The aim of this study was to determine the rate of indocyanine green (ICG) staining of bone and soft-tissue tumours, as well as the stability and accuracy of ICG fluorescence imaging in detecting tumour residuals during surgery for bone and soft-tissue tumours. Methods. ICG fluorescence imaging was performed during surgery in 34 patients with bone and soft-tissue tumours. ICG was administered intravenously at a dose of 2 mg/kg over a period of 60 minutes on the day prior to surgery. The tumour stain rate and signal-to-background ratio of each tumour were post hoc analyzed. After tumour
