Most injuries to the femoral nerve are iatrogenic in origin and occur during resection of large retroperitoneal tumours. When the defect is considerable a
We report 17 patients who had grafting of the common peroneal nerve after traction injuries. Sixteen were reviewed at a median follow-up of 36 months. The nerve gap ranged from 7 to 20 cm. A functionally satisfactory result was achieved in six patients (37.5%), a fair result in six and a poor result in four. Seven patients had, in addition, a posterior tibialis tendon transfer; this improved the result in five. Grafting produced some satisfactory results even when the nerve gap was as long as 20 cm.
We investigated the predictive value of intra-operative
neurophysiological investigations in obstetric brachial plexus injuries.
Between January 2005 and June 2011 a total of 32 infants of 206
referred to our unit underwent exploration of the plexus, including
neurolysis. The findings from intra-operative electromyography,
sensory evoked potentials across the lesion and gross muscular response
to stimulation were evaluated. A total of 22 infants underwent neurolysis
alone and ten had microsurgical reconstruction. Of the former, one
was lost to follow-up, one had glenoplasty and three had subsequent
nerve reconstructions. Of the remaining 17 infants with neurolysis,
13 (76%) achieved a modified Mallet score >
13 at a mean age of
3.5 years (0.75 to 6.25). Subluxation or dislocation of the shoulder
is a major confounding factor. The positive predictive value and
sensitivity of the intra-operative EMG for C5 were 100% and 85.7%,
respectively, in infants without concurrent shoulder pathology.
The positive and negative predictive values, sensitivity and specificity
of the three investigations combined were 77%, 100%, 100% and 57%, respectively. In all, 20 infants underwent neurolysis alone for C6 and three
had reconstruction. All of the former and one of the latter achieved
biceps function of Raimondi grade 5. The positive and negative predictive
values, sensitivity and specificity of electromyography for C6 were
65%, 71%, 87% and 42%, respectively. Our method is effective in evaluating the prognosis of C5 lesion.
Neurolysis is preferred for C6 lesions. Cite this article:
Aims. Orthopaedic surgery requires grafts with sufficient mechanical strength. For this purpose, decellularized tissue is an available option that lacks the complications of autologous tissue. However, it is not widely used in orthopaedic surgeries. This study investigated clinical trials of the use of decellularized tissue grafts in orthopaedic surgery. Methods. Using the ClinicalTrials.gov (CTG) and the International Clinical Trials Registry Platform (ICTRP) databases, we comprehensively surveyed clinical trials of decellularized tissue use in orthopaedic surgeries registered before 1 September 2022. We evaluated the clinical results, tissue processing methods, and commercial availability of the identified products using academic literature databases and manufacturers’ websites. Results. We initially identified 4,402 clinical trials, 27 of which were eligible for inclusion and analysis, including nine shoulder surgery trials, eight knee surgery trials, two ankle surgery trials, two hand surgery trials, and six peripheral

Our unit has pursued a policy of using donor nerves from the same limb for grafting. Nerves which have already been affected by the primary injury are selected where possible, thus avoiding any new sensory deficit. 36 of the 41 brachial plexus repairs were available for outcome data collected prospectively over 2 years. Over a nine year period, donor nerves used for the 41 brachial plexus repairs included the lateral cutaneous nerve of the forearm, superficial radial, medial cutaneous of the forearm, ulnar and sural nerves. Patients were grouped into having injured

Abstract. Background/Objectives. The incidence of reverse total shoulder replacement (rTSR) implantation is increasing globally, but apprehension exists regarding complications and associated challenges. We retrospectively analysed the senior author's series of rTSR from a tertiary centre using the VAIOS shoulder system, a modular 4th generation implant. We hypothesised that the revision rTSR cohort would have less favourable outcomes and more complications. Methods. 114 patients underwent rTSR with the VAIOS system, over 7 years. The primary outcome was implant survival. Secondary outcomes were Oxford shoulder scores (OSS), radiographic analysis (scapular notching, tuberosity osteolysis, and periprosthetic radiolucent lines) and complications. Results. There were 55 Primary rTSR, 31 Revision rTSR and 28 Trauma rTSR. Implant survival: Primary rTSR- 0 revisions, average 3.35-year follow-up. Revision rTSR-1 revision (4.17%), average 3.52-year follow-up. Trauma rTSR- 1 revision (3.57%), average 4.56-year follow-up OSS: Average OSS improved from 15.39 to 33.8 (Primary rTSR) and from 15.11 to 29.1 (Revision rTSR). Average post-operative OSS for the Trauma rTSR was 31.4 Radiological analysis and complications: Low incidence of scapular notching One hairline fracture below the tip of stem, noted incidentally, which required no treatment. One periprosthetic fracture after alcohol related fall. Treated non-surgically One joint infection requiring two-stage revision to rTSR. One dislocation noted at 2 year follow up. This patient had undergone
Introduction and Objectives: Muscular neurotisation is one of the reconstructive techniques used in peripheral nerve surgery. A funded study was designed to evaluate function and maturation of the motor endplate in reconstructions done using free and vascularized
A previously fit and well 58 year old male suffered from a bilateral psoas haematoma (PH) following 52 days of veno-venous extracorporeal membranous oxygenation (VV-ECMO) for severe Coronavirus disease (COVID-19), refractory to all non-invasive and medical therapies. He developed multiple complications, including inability to walk or weight-bear, due to lumbar plexopathy triggered by bilateral PH compression, compounded by COVID-19-related mononeuritis multiplex. The patient was referred to our institution with a known diagnosis of bilateral PH and after spinal multidisciplinary team (MDT) input, was deemed not for surgical or interventional radiology treatments. The patient received extensive neurorehabilitation, coordinated by multiple MDTs. Although PH has been correlated to COVID-19, to the best of our knowledge this is the first reported case of such a complex presentation resulting in a dramatic bilateral PH. Health records from 3 large UK teaching hospitals were collected regarding treatment and follow up appointments, following patient's written informed consent. Patient's comorbidities, duration in hospital units, MDT inputs, health assessments, mobilisation progress and neurologic assessments, were all recorded. Data was collected retrospectively then prospectively due to lengthy in-patient stay. The literature review was conducted via PubMed and open access sources, selecting all the relevant studies and the ECMO guidelines. Patient received treatment from 3 different units in 3 hospitals over 212 days including 103 days in neurorehabilitation. Involvement of physiotherapy, dietitians, speech and language teams, neurologist, neurophysiotherapists, occupational therapists was required. The patient progressed from a bed-bound coma and inability to walk, to standing with lower limb backslab at discharge. Additionally, he was referred for elective exploratory surgery of the psoas region for scar debridement and potential

Peripheral nerve injuries (PNI) occur in 10% of combat casualties. In the immediate field-hospital setting, an insensate limb can affect the surgeon's assessment of limb viability and in the long-term PNI remain a source of considerable morbidity. Therefore the aims of this study are to document the recovery of combat PNI, as well as report on the effect of current medical management in improving functional outcome. In this study, we present the largest series of combat related PNI in Coalition troops since World War II. From May 2007 – May 2010, 100 consecutive patients (261 nerve injuries) were prospectively reviewed in a specialist PNI clinic. The functional recovery of each PNI was determined using the MRC grading classification (good, fair and poor). In addition, the incidence of neuropathic pain, the results of
Evaluations of 32 adults with 50 complete digital nerve injuries were made more than 1 year after surgery. Twenty patients were men and 12 were women. The mean age of the patients at operation was 30 years. The mean follow-up time was 2 years. Patients were excluded if they had a skin graft, had a second surgery after digital nerve repair or graft, were diagnosed with diabetes, had additional proximal nerve injuries, had postoperative infections, had a complete digital amputation or had a dorsal digital nerve injury. According to the initial injury mechanism, patients were classified into three grades : grade I was defined as a sharp, clean-cut injury, grade II was mild crush and grade III was a severe crush injury. Overall, there were 30 primary digital nerve repairs, 12 secondary repairs and 8 secondary
