The aim of this study is to introduce and investigate the efficacy
and feasibility of a new vertebral osteotomy technique, vertebral
column decancellation (VCD), for rigid thoracolumbar kyphotic deformity
(TLKD) secondary to ankylosing spondylitis (AS). We took 39 patients from between January 2009 and January 2013
(26 male, 13 female, mean age 37.4 years, 28 to 54) with AS and
a TLKD who underwent VCD (VCD group) and compared their outcome
with 45 patients (31 male, 14 female, mean age 34.8 years, 23 to
47) with AS and TLKD, who underwent pedicle subtraction osteotomy
(PSO group), according to the same selection criteria. The technique
of VCD was performed at single vertebral level in the thoracolumbar
region of AS patients according to classification of AS kyphotic
deformity. Pre- and post-operative chin-brow vertical angle (CBVA),
sagittal vertical axis (SVA) and sagittal Cobb angle in the thoracolumbar
region were reviewed in the VCD and PSO groups. Intra- , post-operative
and general complications were analysed in both group.Aims
Patients and Methods
We report a new surgical technique for the treatment
of traumatic dislocation of the carpometacarpal (CMC) joint of the
thumb. This is a tenodesis which uses part of the flexor carpi radialis. Between January 2010 and August 2013, 13 patients with traumatic
instability of the CMC joint of the thumb were treated using this
technique. The mean time interval between injury and ligament reconstruction
was 13 days (0 to 42). The mean age of the patients at surgery was
38 years: all were male. At a mean final follow-up of 26 months (24 to 29), no patient
experienced any residual instability. The mean total palmar abduction
of the CMC joint of the thumb was 61° and the mean radial abduction
65° The mean measurements for the uninjured hand were 66° (60° to
73°) and 68° (60° to 75°), respectively. The mean Kapandji thumb
opposition score was 8.5° (8° to 9°). The mean pinch and grip strengths
of the hand were 6.7 kg (3.4 to 8.2) and 40 kg (25 to 49), respectively.
The mean Disabilities of the Arm, Shoulder, and Hand questionnaire
score was 3 (1 to 6). Based on the Smith and Cooney score, we obtained
a mean score of 85 (75 to 95), which included four excellent, seven
good, and two fair results. Our technique offers an alternative method of treating traumatic
dislocation of the CMC joint of the thumb: it produces a stable
joint and acceptable hand function. Cite this article:
We report a new surgical technique of open carpal
tunnel release with subneural reconstruction of the transverse carpal
ligament and compare this with isolated open and endoscopic carpal
tunnel release. Between December 2007 and October 2011, 213 patients with carpal
tunnel syndrome (70 male, 143 female; mean age 45.6 years; 29 to
67) were recruited from three different centres and were randomly
allocated to three groups: group A, open carpal tunnel release with
subneural reconstruction of the transverse carpal ligament (n =
68); group B, isolated open carpal tunnel release (n = 92); and
group C, endoscopic carpal tunnel release (n = 53). At a mean final follow-up of 24 months (22 to 26), we found no
significant difference between the groups in terms of severity of
symptoms or lateral grip strength. Compared with groups B and C,
group A had significantly better functional status, cylindrical
grip strength and pinch grip strength. There were significant differences
in Michigan Hand Outcome scores between groups A and B, A and C,
and B and C. Group A had the best functional status, cylindrical
grip strength, pinch grip strength and Michigan Hand Outcome score. Subneural reconstruction of the transverse carpal ligament during
carpal tunnel decompression maximises hand strength by stabilising
the transverse carpal arch. Cite this article:
The aim of this study was to assess a specific
protocol for the treatment of patients with a parosteal osteosarcoma of
the distal femur with limb salvage involving hemicortical resection
and reconstruction using recycled pasteurised autograft and internal
fixation. Between January 2000 and January 2010, 13 patients with
a mean age of 26.5 years (17 to 39) underwent this procedure. All
the tumours were staged according to Enneking’s criteria: there
were eight stage IA tumours and five stage IB tumours. The mean
follow-up was 101.6 months (58 to 142), and mean post-operative
Musculoskeletal Tumour Society functional score was 88.6% (80% to
100%) at the final follow-up. All the patients had achieved bony
union; the mean time to union was 11.2 months (6 to 18). Local recurrence
occurred in one patient 27 months post-operatively. No patient had
a pulmonary metastasis. A hemicortical procedure for the treatment of a parosteal osteosarcoma
is safe and effective. Precise pre-operative planning using MRI
is essential in order to define the margins of resection. Although
it is a technically demanding procedure, gratifying results make
it worthwhile for selected patients. Cite this article:
Nonunion of the humerus with bone loss and shortening due to osteomyelitis is rare but difficult to treat. We describe our experience with a callus distraction technique using a monolateral external fixator for the treatment of this condition. Between October 1994 and January 2004, 11 patients were treated. There were seven males and four females, with a mean age of 14 years (10 to 17). The mean bone loss was 1.9 cm (1 to 2.7) and the mean length discrepancy in the upper limb was 5.6 cm (3.5 to 8.0). The mean follow-up was for 106 months (54 to 166). The mean external fixation index was 34.8 days/cm (29.8 to 40.5). The mean lengthening was 9.5 cm (5.5 to 13.4). There were seven excellent results, three good and one poor. There were nine excellent functional results and two good. The treatment of humeral nonunion with bone loss and shortening due to osteomyelitis by callus distraction is a safe and effective means of improving function and cosmesis.
We present a retrospective study of 27 patients treated by callus distraction using a unilateral external fixator of our own design for nonunion with bone loss and shortening of the femur caused by suppurative osteomyelitis. The unilateral external fixator was used either alone or in combination with an intramedullary nail. The mean age of the patients was 13.6 years (8 to 18). The fixator was used alone in 13 patients and with an intramedullary nail in 14. The bone results at a mean follow-up of 88 months (37 to 144) were excellent in 16 patients and good in 11. The functional results were excellent in 18 patients and good in nine. However, four patients still had draining sinuses at the latest follow-up. A residual deformity greater than 7° was present in seven femora, but this did not adversely affect function or require further treatment.
We report our experience of the use of callus distraction with a monolateral fixator for the treatment of acquired radial club-hand deformity after osteomyelitis. Between 1994 and 2004, 13 patients with a mean age of eight years (4 to 15) were treated by callus distraction with a monolateral fixator after a preliminary period of at least four weeks in a corrective short-arm cast. All patients achieved bony union and were satisfied with the functional and cosmetic outcome. There were no major complications, but three patients required cancellous bone grafting at the docking site for delayed union. Local treatment and oral antibiotics were required for pin-site infection in six patients. There were no deep infection or recurrence of osteomyelitis.
