Clinical Trial
INTRODUCTION
Stump hyperhidrosis is a common condition after lower limb amputation. It affects the prosthesis use, and the quality of life of patients. Several case reports tried to prove benefit of using Botulinum toxin in its treatment.
AIM
This study was to conduct a larger workforce clinical trial and to demonstrate benefits of botulinum toxin injection in the treatment of stump hyperhidrosis.
METHODS
A prospective study was conducted. War amputees who complained of annoying excessive sweating of the stump were included. They received intradermal injection of botulinum toxin A in the residual limb area in contact with prosthetic socket. Abundance of sweating and degree of functional discomfort associated with it were assessed before, after 3 weeks, 6 and 12 months.
RESULTS
Seventeen male patients, followed for post-traumatic limb amputation were included in the study. Discomfort and bothersome in relation to Hyperhidrosis did decrease after treatment (p<0,001). Reported satisfaction after 3 weeks was 73,33%. Improvement of prothesis loosening up after 3 weeks was 72,5% [±15,6]. Mean injection-induced pain on the visual analogue scale was 5.17/10 (±1.58). The mean interval after the onset of improvement was 5.13 days [min:3, max:8]. The mean time of improvement was 10.4 months after the injection [min:6, max:12]. No major adverse events were reported following treatment.
CONCLUSION
Intradermal injections of botulinum toxin in the symptomatic treatment of stump hyperhidrosis are effective and have few adverse effects. It improves the quality of life of our patients thanks to a better tolerance of the prosthesis.

Aim To investigate the effect of direct epineural electrical stimulation of the nerve on the nature of reparative processes in the bone stump. Methods Three series of experiments were carried out with amputation of the thigh in the middle third and muscle plasty. In the 1st and 2nd experimental series a perineural catheter was brought to the stump of the sciatic nerve, through which mechanical irritation of the nerve was performed for 20 days daily for 20 minutes. In the 2nd series, an electrode was added to the nerve and epineural electrical stimulation was performed daily for 20 days. Animals of the 3rd series served as control. The observation periods were 1, 3, 6 months. Histological research method with filling vessels with ink-gelatin mixture was applied. Results In the 1st series, there was a sharp distortion of the reparative process, which consisted of a violation of microcirculation, changes in shape, resorption of the cortical diaphyseal plate, fractures, deformations. In most experiments of the 2nd series, organotypic stumps were formed with normalization of microcirculation. In the 3rd series, results of the formation of the stump were better than in the 1st, but worse than in the 2nd series. Conclusions Painful nerve irritation after amputation leads to a significant disturbance of microcirculation and reparative regeneration at the end of the bone stump with the development of pathological restructuring of bone tissue. Electrostimulation of the nerve improves microcirculation and reparative regeneration of the bone tissue.

Orthopedic Research and Reviews 2024To study the peculiarities of peroneal stump remodelling after transtibial amputation in the process of prosthesis usage.
AIM
To study the peculiarities of peroneal stump remodelling after transtibial amputation in the process of prosthesis usage.
MATERIAL AND METHODS
A histological study of the ends of the stumps of the fibula in 68 patients was performed. Terms after amputation: 2-8 years.
RESULTS
In the 1st group the stumps with the reparative process completion were formed. In the 2nd group there were sharp disturbances of the reparative process with the formation of the cone-shaped end. In the 3rd group there was a pronounced periosteal bone formation with changes in the shape and structure of bone tissue and incompleteness of the reparative process.
CONCLUSION
Absence of balloting of the fibula stump and dense overlapping of the medullary cavity by muscles promotes complete remodelling of the fibula remnant with preservation of its organicity. Pathological remodelling of the fibula stump occurs due to its hypermobility, repeated traumatisation of the forming regenerate, neuritis of the peroneal nerve, osteogenesis disorders and structural and functional mismatch of the bone tissue to the loading conditions in the prosthesis. Morphological signs of pathological remodelling are the lack of completion of reparative regeneration, intensive bone tissue remodelling lasting for years with pronounced resorption and appearance of immature bone structures, fractures of the cortical diaphyseal layer, residual limb deformities with formation of a functional regenerates, narrowing and closure of the medullary canal with conglomerate with soft tissue inclusions. The anatomical inferiority of bone tissue formed in the process of remodelling of the fibula remnant creates a threat of stress fracture.

Review
Deer antlers are the only known mammalian organ that, once lost, can fully grow back naturally. Hence, the antler offers a unique opportunity to learn how nature has solved the problem of mammalian epimorphic regeneration (EpR). Comprehensive comparisons amongst different types of EpR reveal that antler renewal is fundamentally different from that in lower vertebrates such as regeneration of the newt limb. Surprisingly, antler renewal is comparable to wound healing over a stump of regeneration-incompetent digit/limb, bone fracture repair, and to a lesser extent to digit tip regeneration in mammals. Common to all these mammalian cases of reaction to the amputation/mechanical trauma is the response of the periosteal cells at the distal end/injury site with formation of a circumferential cartilaginous callus (CCC). Interestingly, whether the CCC can proceed to the next stage to transform to a blastema fully depends on the presence of an interactive partner. The actual form of the partner can vary in different cases with the nail organ in digit tip EpR, the opposing callus in bone fracture repair, and the closely associated enveloping skin in antler regeneration. Due to absence of such an interactive partner, the CCC of a mouse/rat digit/limb stump becomes involuted gradually. Based on these discoveries, we created an interactive partner for the rat digit/limb stump through surgically removal of the interposing layers of loose connective tissue and muscle between the resultant CCC and the enveloping skin after amputation and by forcefully bonding two tissue types tightly together. In so doing partial regeneration of the limb stump occurred. In summary, if EpR in humans is to be realized, then I envisage that it would be more likely in a manner akin to antler regeneration rather to that of lower vertebrates such as newt limbs.

Aim To study the character of blood circulation in the bone stump at tight and loose closure of the medullary cavity. Methods Two series of experiments on 39 rabbits with mid-third femoral amputation and muscular plasty were carried out. In the 1st (experimental) series, the bone scapula was closed by thin cortical autograft taken from the epimetaphyseal area, and then the muscles were sutured, and in the 2nd - the scapula was closed by myoplasty only. Follow-up periods: 1st series - 7, 14, 21 days and 1, 3, 6 months, 2nd series - 1, 3, 6 months. Histological methods with infusion of vessels with ink-gelatin mixture and morphometry was used. Results In the 1st series there was a rapid restoration of the disturbed macro- and microcirculation due to the reserve sources of blood circulation and the development of extravascular ways of microcirculation. In the 2nd series, blood circulation recovery was significantly slower and occurred mainly due to the development of extravascular microcirculatory pathways. Conclusion The study established undeniable usefulness of tight closure of the bone marrow cavity during amputation.

OBJECTIVE
Major amputation of a lower limb is a traumatic experience that causes physical and psychosocial disabilities. This study set out to ascertain how anxiety and depression symptoms changed during the three months following the amputation.
MATERIALS AND METHODS
A prospective longitudinal observational study was conducted between October 1, 2019, and January 1, 2021, in the Department of Vascular Surgery and the Department of Orthopedic Traumatology of the Ibn Sina Hospital Center in Rabat, Morocco. The study assesses symptoms of anxiety and depression in patients who have undergone a major lower limb amputation over a three-month interval.
RESULTS
In patients who had undergone a major lower limb amputation, the prevalence of anxiety and depression symptoms was very high immediately postoperatively (47.4% and 79.2%, respectively), with a significant decrease in these symptoms. Three months later, anxiety was reported in 24.4% of cases, and depressive symptoms in 65.1% of cases. Age, amputation level, stump pain, phantom limb pain, re-amputation, and emergency amputation were all associated with an increased risk of anxiety and depression. The patient's psychological preparation prior to the amputation, the anesthetic technique used during the procedure, the patient's mobility, and the patient's post-amputation professional status were all protective factors.
CONCLUSION
Our research findings bolster the necessity of promptly evaluating and managing anxiety and depression in the initial three months following major lower limb amputation. Thus, we believe that amputee patients ought to receive a formal psychological evaluation, which could be helpful, particularly for those whose anxiety or depression symptoms did not improve after three months.

Review
During the 1970s, scientists first used botulinum toxin to treat strabismus. While testing on monkeys, they noticed that the toxin could also reduce wrinkles in the glabella area. This led to its widespread use in both medical and cosmetic fields. The objective of the study was to evaluate the potential use of Botox in managing post-operative contracture after below-knee amputation. We conducted a systematic review In Pubmed, Cochrane Library, Embase, and Google Scholar using the MESH terms Botox, botulinum toxin, post-operative contracture, amputation, and below knee amputation. Our goal was to evaluate the potential use of Botox to manage post-operative contracture in patients who have undergone below-knee amputation. Our findings show evidence in the literature that Botox can effectively manage stump hyperhidrosis, phantom pain, and jumping stump, but no clinical trial has been found that discusses the use of Botox for post-operative contracture. Botox has been used in different ways to manage spasticity. Further studies and clinical trials are needed to support the use of Botox to manage this complication.

INTRODUCTION
Diabetic-related foot condition is one of the most debilitating complications with a higher rate of failure in limb correction, reconstruction, or salvage surgery. Amputation is the final option after other surgical treatments have failed. Major amputation increases energy consumption, resulting in high dependency, decreased mobility, and poor prognosis. Consequently, minor amputation is preferred to resolve these problems but elevated wound complications leading to inadequate prosthesis fit, became a detriment to minor amputation. Strict selection of patients is crucial to ensure success and good functional outcomes as demonstrated in this retrospective study of this case series. Methods This case series included six patients who underwent Pirogoff amputation with the modification described by Nather and reported the procedure's outcome. The inclusion criteria for subjects were the presence of palpable posterior tibial artery (PTA) or at least biphasic Doppler signal and ankle-brachial systolic index (ABSI) more than 0.70. Other demographic data as well as hematological, inflammatory, and biochemical parameters that may affect wound healing such as Hb, HbA1c, ESR, CRP, WBC, and albumin were recorded as well. The rate and time for wound healing and bone union, presence of complications, and final ambulatory status of patients were determined as the outcome of this study.
RESULTS
All of the patients had diabetic foot infections involving only the forefoot region with the presence of either palpable PTA or biphasic Doppler signal. Although the majority of the cases had deranged blood parameters, soft tissue and bone healing were achieved at variable times. Four had good outcomes as they were able to ambulate. One case was complicated with chronic wound dehiscence and another one had Pirogoff stump infection and required transtibial amputation.
CONCLUSION
With strict selection criteria, Pirogoff amputation may provide a good functional outcome with a lesser degree of complications compared to major amputation.

BACKGROUND
A 72-year-old man with a history of delayed presentation for severe right lower extremity burns underwent through-knee amputation complicated by periprosthetic distal femur osteomyelitis. Subsequent transfemoral amputation was complicated by Stage IVB Cierny-Mader osteomyelitis despite appropriate medical and surgical treatment.
METHODS
Due to the presence of threatened proximal femur intramedullary nail from prior intertrochanteric femur fracture, inability to further shorten femur, and lack of local soft-tissue options, we performed soft tissue reconstruction with free gracilis flap. The free gracilis flap was pulled proximally through the femoral canal to obliterate intramedullary dead space and provide distal femoral stump coverage.
RESULTS
The stump was fully healed upon 6-month follow-up with computerized tomography demonstrating continued presence of gracilis flap within the femoral canal and no evidence of osteomyelitis. At 1-year follow-up, the patient was ambulatory using a prosthetic without recurrence of osteomyelitis.
CONCLUSIONS
Previous descriptions of intramedullary free muscle flaps for the treatment of osteomyelitis are limited in number, with its function being limited to dead-space obliteration. This report presents intramedullary free gracilis flap to be a viable option in above-knee amputees for combined dead space obliteration and stump resurfacing in the context of recurrent osteomyelitis.
