The primary goal is to preserve thumb integrity and functionality to the greatest extent possible, even in cases involving very small amputated parts. In this article, we present a case in whom the seemingly non-replantable dorsal skin-nail composite tissue of the thumb could be successfully replanted with a single artery anastomosis. No additional procedures were required, and complete recovery was achieved. In conclusion, given the unique vascular structure of the thumb, all amputated parts should be carefully evaluated for replantation. Replanting a partially amputated finger yields superior functional and cosmetic outcomes compared to any reconstructive method.

METHODS: An overall healthy 48-year-old man suffered a left foot mangled crush injury resulting in a post-transmetatarsal amputation and subsequently developing a painful neuroma on the plantar surface of the foot. To avoid the zone of injury, targeted muscle reinnervation was used to treat the neuroma by coapting the tibial nerve to the motor point of the flexor hallucis longus (FHL) muscle. At 1-year follow-up, the patient reported no pain at rest, returned to work, and could ambulate with an orthosis for 30 minutes.
CONCLUSIONS: Rare tibial nerve coaptations to the FHL could serve as a treatment option for patients with neuromas in traumatic postmetatarsal amputation.

OBJECTIVE: To describe and evaluate the combination of osseointegration and nerve transfers in 3 transhumeral amputees.
METHODS: Case series.
METHODS: Three male patients with a unilateral traumatic transhumeral amputation.
METHODS: Patients received a combination of osseointegration and targeted muscle reinnervation surgery. Rehabilitation included graded weight training, range of motion exercises, biofeedback, table-top prosthesis training, and controlling the actual device. The impairment in daily life, health-related quality of life, and pain before and after the intervention was evaluated in these patients. Their shoulder range of motion, prosthesis embodiment, and function were documented at a 2- to 5-year follow-up.
RESULTS: All 3 patients attended rehabilitation and used their myoelectric prosthesis on a daily basis. Two patients had full shoulder range of motion with the prosthesis, while the other patient had 55° of abduction and 45° of anteversion. They became more independent in their daily life activities after the intervention and incorporated their prosthesis into their body scheme to a high extent.
CONCLUSIONS: These results indicate that patients can benefit from the combined procedure. However, the patients\' perspective, risks of the surgical procedures, and the relatively long rehabilitation procedure need to be incorporated in the decision-making.

The management of complex and severe lower-extremity injuries is challenging for the orthopedic surgeon. When the primary or secondary closure of the defect is not feasible, complex procedures with graft (split-thickness or full-thickness) or flap (pedicled or free) are required. These procedures are performed by specialized plastic surgeons and are at high risk for adverse effects, even high morbidity among both the donor and acceptor sites. Furthermore, split-thickness skin grafts (STSGs) often lead to unsatisfactory results in terms of mechanical stability, flexibility, and aesthetics due to the lack of underlying dermal tissue. Consequently, dermal substitutes, such as MatriDerm (MedSkin Solutions Dr Suwelack AG, Billerbeck, Germany), have been proposed and further developed as a treatment option addressing the management of full-thickness wound defects in conjunction with STSGs. We aimed to present a case of post-traumatic full-thickness wound defect of the left foot after traumatic amputation of the digits that was treated with MatriDerm combined with autologous STSG. In addition, we performed a systematic review of the literature to delineate the efficacy of the use of MatriDerm combined with STSGs in orthopedic cases exclusively.

This case report explores the management of a traumatic hemipelvectomy-a rare and devastating injury characterized by a high mortality rate. The patient, a 12-year-old male, suffered right lower extremity amputation and right hemipelvectomy due to a deglov-ing injury from a non-vehicle-related accident at another institution. Initially, an urgent reconstruction of the right pelvic region and suprapubic tissue defects was performed using a posterior-based fasciocutaneous flap. Following this, the patient was transferred to the pediatric intensive care unit at our hospital with a suspected diagnosis of necrotizing fasciitis. Treatment included broad spectrum antibiotics and multiple debridements to avert the onset of sepsis. Eventually, reconstruction of a 60 x 25 cm defect covering the lower back, abdomen, gluteal, and pubic regions was achieved through serial split-thickness skin grafts and a pedicled anterolateral thigh flap. The patient made a remarkable recovery, regained mobility with the aid of a walker, and was discharged in good health 22 weeks after the initial accident. This case report underscores the importance of serial debridements in preventing sepsis, the use of negative pres-sure vacuum dressing changes, the initiation of broad-spectrum antibiotics based on culture results during debridements, and prompt closure of the defect to ensure survival after traumatic hemipelvectomy. Familiarization with the principles discussed here is crucial to minimizing mortality rates and optimizing outcomes for this rare injury.

Nail bed reconstruction is crucial after fingertip trauma, impacting both function and aesthetics. In this article, the authors describe a case of partial distal phalanx amputation of the index finger with laceration of the nail bed\'s remaining part. A traumatically elevated skin-fat flap covered the exposed bone on the fingertip, preserving finger length and sensitivity on the radial side. A full-thickness skin graft from the forearm closed a secondary defect on the finger pulp. Nail bed suturing prevented scarring and nail deformity, and a temporary artificial plastic nail replacement maintained the nail bed\'s shape. Temporary artificial nail replacements protect the regenerating fingertip bed, promote healing, and prevent nail deformities. Proper adaptation of lacerated nail bed edges, supported by either the patient\'s own nail or a temporary artificial nail, is crucial for optimal fingertip restoration, including proper nail shape.

METHODS: A 4-year-old girl patient presented with complete amputation of the second toe close to the distal interphalangeal joint. Replantation was performed using a novel midlateral approach. The procedure used the dorsal subcutaneous vein on the foot as a graft for the artery. Four months postoperatively, the toe healed without any complication. The patient reported pain-free physical exercise without limitations in daily activity.
CONCLUSIONS: This report demonstrates that this approach has the potential to provide a safe and viable alternative for treating toe amputations and offers advantages such as simplified artery identification, straightforward anastomosis, and improved vein graft harvesting.

Crush injury with bone loss results in shortening the length of the thumb. Most of the immediate intervention is amputation and stump closure. Revision amputation with stump closure gives loss of functional length and the patient is unable to do daily activities as before. In most of all hand functions, the opposition of the thumb plays an important role. Reconstruction of the thumb with iliac crest bone graft with its functional length is one of the major achievements for the patient. As in our case, the patient is right-hand dominant he is more concerned about the functional length of the thumb, whatever the aesthetic appearance. Here we present a case of a 24-year-old male with thumb reconstruction in a severely injured thumb with loss of bone and soft tissue just distal to the base of the proximal phalanx. Nine months postoperatively, the patient showed a great outcome with restored thumb length, function, grip strength, and a good range of motion.

BACKGROUND Circumcision is commonly performed in males, especially in Jewish and Muslim cultures, and is considered a safe surgical procedure with a low complication rate. Major complications, such as partial and total penile amputation, can occur, but those are rare complications. However, high replantation success rates have been reported and reviewed. CASE REPORT We describe the case of an 8-year-old boy who experienced total penile amputation during ritual circumcision performed by a layperson outside the hospital setting. Microsurgical penile replantation was performed after an ischemic period of 16 hours 43 minutes, with successful outcomes and without any major complications. In our technique, we repaired both dorsal and deep cavernosal vessels. At 1-year postoperative period, the results of two-point discrimination test were 4 mm, 7 mm, and 7 mm on the dorsal part, ventral part, and glans, respectively. After a follow-up period of 4 years, there were no late complications such as penile deformity, urethral fistula, urethral stenosis, absence of penile sensation, or erectile dysfunction. The results of two-point discrimination test were 3 mm, 5 mm, and 5 mm on the dorsal part, ventral part, and glans, respectively. The patient also experienced good penile sensation, morning erection, satisfaction with the cosmetic outcome, and a peak urine flow rate of 21 mL/s with a consistently strong void stream and a low postvoid residual urine volume of 20 mL. CONCLUSIONS Our experience suggests that a short ischemic time, prompt surgical correction, microscopic technique of replantation, and intensive postoperative care can result in good functional outcomes.

Amputation of the testis is very rare in clinical situations; therefore, most surgeons have no experience with an amputated testis. In this case, a 31-year-old male with schizophrenia amputated both testes due to self-mutilation. We performed replantation surgery via microscopy. On postoperative day 1, he removed his right testis by using his hand, even though his hands were restrained. The second attack disrupted the viability of the right testis. However, after proper management, we checked the normal sex hormone level by preserving the replanted left testis. We evaluated the viability of the replanted testis by performing five examinations, namely, intraoperative indocyanine green injection, testicular scan with technetium pertechnetate, contrast-enhanced computerized tomography, Doppler ultrasonography, and serum testosterone level. In this report, we aimed to describe our rare experience about management with replantation of the amputated testes and evaluation of their viability.
