BACKGROUND: Prosthetic hands with a myoelectric interface have recently received interest within the broader category of hand prostheses, but their high cost is a major barrier to use. Modern three-dimensional (3D) printing technology has enabled more widespread development and cost-effectiveness in the field of prostheses. The objective of the present study was to evaluate the clinical impact of a low-cost 3D-printed myoelectric-interface prosthetic hand on patients' daily life. METHODS: A prospective review of all upper-arm transradial amputation amputees who used 3D-printed myoelectric interface prostheses (Mark V) between January 2016 and August 2017 was conducted. The functional outcomes of prosthesis usage over a 3-month follow-up period were measured using a validated method (Orthotics Prosthetics User Survey–Upper Extremity Functional Status [OPUS-UEFS]). In addition, the correlation between the length of the amputated radius and changes in OPUS-UEFS scores was analyzed. RESULTS: Ten patients were included in the study. After use of the 3D-printed myoelectric single electromyography channel prosthesis for 3 months, the average OPUS-UEFS score significantly increased from 45.50 to 60.10. The Spearman correlation coefficient (r) of the correlation between radius length and OPUS-UEFS at the 3rd month of prosthetic use was 0.815. CONCLUSIONS: This low-cost 3D-printed myoelectric-interface prosthetic hand with a single reliable myoelectrical signal shows the potential to positively impact amputees' quality of life through daily usage. The emergence of a low-cost 3D-printed myoelectric prosthesis could lead to new market trends, with such a device gaining popularity via reduced production costs and increased market demand.

Amputation of the lower extremities followed by the use of an artificial leg is very common. However, malignancy arising in an amputation stump is an extremely rare event. In this report, we describe a case of squamous cell carcinoma arising in the amputation stump of a 56-year-old Korean man. To the best of our knowledge, similar cases have not been previously reported in Korea.

Amputation stump pains can be developed in amputation sites after high voltage electrical burn injuries. We experienced one case of these severe stump pains in an upper extremity amputation patient. A 35-year-old man had a 38% total body surface area high voltage electrical burn. The patient underwent skin grafting and left shoulder disarticulation. During the rehabilitation period, he complained about severe stump area pains and phantom pains. We injected 0.5% Bupivacaine and Triamcinolone on the stump neuroma site but the pain sustained. After extracorporeal shock wave therapy (ESWT,) the pain subsided and did not recur. The patient was satisfied with functional and pain outcomes, so we report this case.

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

OBJECTIVE: To investigate the effect of extracorporeal shock wave therapy (ESWT) on painful stump neuroma. METHODS: Thirty patients with stump neuroma at the distal end of an amputation site were assigned randomly to the ESWT group (n=15) and the transcutaneous electrical nerve stimulation (TENS)+desensitization+pharmacological treatment group (n=15). For 3 weeks, the ESWT group received a weekly session involving 1,500 pulses at 0.10 mJ/mm2, while the control group was treated 10 times each, 40 minutes per day with TENS and desensitization treatment, and daily medication for 3 weeks. ESWT stimulation was given by focusing on the area at the neuroma site clearly identified by ultrasound. RESULTS: The changes in the McGill pain questionnaire were 38.8+/-9.0 prior to treatment and 11.8+/-3.1 following the treatment. The corresponding values for the control group were 37.2+/-7.7 and 28.5+/-10.3. The changes between groups were significantly different (p=0.035). The change in visual analog scale prior to and after treatment was 7.0+/-1.5 and 2.8+/-0.8 in the ESWT group, respectively, and 7.2+/-1.4 and 5.8+/-2.0 in the control group. These changes between the groups were also significantly different (p=0.010). The outcome in the pain rating scale also showed significant differences between groups (p<0.001). Changes in neuroma size and pain pressure threshold (lb/cm2) were not significantly different between groups (p>0.05). CONCLUSION: The study findings imply that ESWT for stump neuroma is superior to conventional therapy.

Vacuum-assisted wound healing has been proven to be more efficacious than conventional dressings. Vacuum dressing has been frequently modified given the restrictions in resources available. Here we present a modified method of vacuum dressing by using surgical or gynaecological gloves for lower and upper limb wounds. Vacuum dressing was applied with parts of a surgical or gynaecological glove and Opsite with T-tailing of the suction outlet. Vacuum-assisted wound healing using the surgical gloves showed relatively good wound healing in the amputation stump, finger, arm, and leg in the cases studied.

Marjolin's ulcer is a malignant lesion, which arises in a chronic wound. When squamous cell carcinoma occurs in Marjolin's ulcer, the prognosis is known to be worse than that of cutaneous squamous cell carcinoma, due to other etiologies. A 56-year-old male who was diagnosed as chronic osteomyelitis was recommended for a surgical amputation of the left lower leg. After amputation, the histology of chronic ulcer revealed squamous cell carcinoma. In a few months period, multiple suppurative ulcers and nodules appeared near the amputation stump, as well as the proximal sites of the left leg, which appeared to spread rapidly. Biopsy of a representative lesion and positron emission tomography-computed tomography revealed a metastatic squamous cell carcinoma and malignant lymphadenopathy. Aggressive amputation without appropriate preoperative evaluation to detect the locoregional metastasis may be an inadequate option of the treatment for the patient due to a rapid spread of cancer metastasis, which may happen immediately after an amputation. Therefore, it is important to obtain a thorough preoperative evaluation of recalcitrant ulcer from osteomyelitis before the decision to undergo an amputation.

PURPOSE: In cases of high voltage electrical burns, a wound occurs as current enters or leaves the body and is accompanied by deep tissue injury. If upper extremity amputation is inevitable, consideration should be given to the residual limb functions, secondary reconstruction, and wearing of an upper prosthesis. Our hospital has achieved satisfactory outcomes through the use of a pedicled latissimus dorsi (LD) flap in patients undergoing transhumeral amputation and shoulder disarticulation due to upper extremity damage from high voltage electrical burns. METHODS: The study was targeted to five patients who suffered high voltage electrical burns, underwent above-elbow amputation, and were reconstructed in the acute and secondary phases using a pedicled LD flap from January 2005 to December 2011. All patients underwent equilateral pedicled LD flap surgery, with primary closure at the donating site. RESULTS: The average age of patients was 49.6 years (38~64); they were all male. One patient underwent sublayer skin grafting after a pedicled muscular LD flap, and four patients had a pedicled myocutaneous LD flap: one patient among the four had a forearm flap after the pedicled myocutaneous LD flap. All flaps were well adhered, and post-surgical flap reduction and local flaps were performed for adequate sizing and aesthetic improvement. CONCLUSION: In cases of upper arm amputation due to wide upper extremity damage caused by electrical burns, the use of the pedicled LD flap and adequate amputation length made subsequent wearing of a prosthesis possible. The pedicled LD flap procedure allowed reconstruction of a relatively large area of soft tissue and the surgery to the donating site was unproblematic.

The goal of surgery in fingertip amputation is to restore finger length, preserve function and at the same time provide cosmetic acceptability. Treatment options are varied and can range from simple suturing of the stump to microvascular replantation surgery. We report three cases of fingertip amputations in one adult and two pediatric patients treated with non-microsurgical replantation of the fingertip using the palmar "pocket" technique.
