Can locking plate fixation and free Vascularised fibular transfer with skin island achieve good functional outcome in the treatment of large bone defects of Tibia ? A study of 26 cases.

BACKGROUND: Despite the availability of multiple treatment options, management of tibial bone loss continues to be a challenge. Free vascularized fibula graft (FVFG) with a skin paddle offers better advantages over the other methods. We aimed to study the functional outcomes and QALY of patients with large tibial bone defects following FVFG with a locking plate in 26 patients. MATERIALS AND METHODS: We analyzed 26 consecutive patients with large tibial bone defects treated by free vascularized fibular graft (FVFG) and stabilization using a long locking plate between 2009 and 2018. All were followed up for a mean period of 42 months (24 months to 120 months). Bony union, graft hypertrophy, and complications such as stress fracture and infections were assessed. Multivariate regression analysis was performed to identify any association between demographic factors, injury characteristics, treatment-related factors, and fibular hypertrophy. Additionally, The EQ-5D quality-of-life (QOL) indices were obtained using the SF-12 score to evaluate the patients' overall quality of life. RESULTS: The mean age of the patients at the time of presentation was 36.26 yrs (range, 18-60 years). The cause of bone loss was open injury in 16 patients and infected nonunion in 10 patients. Complete union was achieved in 25 patients (96 %) without any requirement of additional surgical procedures. The mean union time of the graft was 4.04 months (range, 3-6 months). The mean fibular hypertrophy calculated by De Boer index was 0.61 %, 11 %, 28.24 % and 52.52 % at 3,6 months and 1 and 2 years respectively. Patients with metaphyseal bone loss have significant fibular hypertrophy. Participants in our study experienced a quality of life equivalent to 0.88 (range 0.79-0.99) of perfect health. CONCLUSIONS: FVFG with skin paddle and LCP fixation for massive tibial bone loss achieved satisfactory outcome and QALY even in the challenging healthcare environment of South India, a developing country.It maintains alignment, promotes graft hypertrophy, and prevents stress fractures.

Options for Restoring Finger Extension in Mangled Forearm Injuries.

Restoration of finger extension in mutilating hand injuries is crucial for restoring prehension and independent use of the hand. Patients often express desire to restore finger extension once finger flexion is achieved. However, the extensive forearm injury precludes use of any of conventional donors like the wrist or finger flexors for transfer to restore finger extension. Two patients with sequelae of mangled forearm injuries, underwent biceps and long head of triceps transfer to the finger extensors to improve opening up of the fingers. We discuss the treatment considerations while planning these transfers and provide the technical details, rehabilitation and outcome of these patients. Both the patients expressed dramatic improvement of their hand function and were satisfied with the outcome. Biceps and long head of triceps could serve as an effective second-line donor for restoration of finger extension when the conventional donors are not available. Level of Evidence: Level V (Therapeutic).

Distal fingertip replantation: indications, strategy and postoperative management.

Distal fingertip replantation is associated with being a technically demanding procedure and dubious outcomes, although it is now performed more frequently across the world. However, the technique and outcomes remain controversial with disagreement among replantation surgeons due to lack of consensus about the indications, intraoperative strategy and postoperative regimes. In this article, we asked six experienced hand surgeons several pertinent questions that every replantation surgeon performing distal fingertip replantation would face in their clinical practice. The article summarizes their responses, which might provide valuable insight to every replantation surgeon in different parts of their career while managing these injuries.

Forearm Deformities in Birth Brachial Plexus Palsy - Patient Profile and Management Algorithm.

Forearm deformities are often seen in children with severe birth brachial plexus palsy (BBPP). They may be either a supination or a pronation deformity and both hinder normal use of the hand and parents often request for corrective surgery. However, the correction of these deformities can be challenging due to a paucity of options. Also, there is less information in literature on the management of forearm deformities in BBPP compared to the information with regard to nerve surgery or correction of shoulder deformities. This article presents a synopsis of incidence, pathogenesis, clinical presentation and parental concerns related to these deformities. The decision-making considerations, management strategies and outcome expectations are also discussed. Patient selection is very crucial, and the treatment plan must be individualised depending on the disability, parental expectations and existing motor power in the involved limb. Correction of both the deformities have different considerations; however, effective correction of these deformities is immensely satisfactory to the patient/parents in terms of improved function and appearance of the limb. Level of Evidence: Level V (Therapeutic).

Recipient Vessel Dissection Technique in Diabetic Foot Patients with Perivascular Fibrosis.

Diabetic foot ulcers are becoming more prevalent, and microsurgical free flaps are gaining popularity in salvaging the foot after postdebridement. The perivascular fibrosis around the recipient vessels often makes the dissection of vessels difficult. In this article, we describe a technique of dissection in such situations where fibrosis and dissection of vessels are fraught with danger. In the period from November 2020 to May 2023, 72 free flap reconstructions of the diabetic foot were done at our institute using this technique, with a success rate of 95.8%.

Replantation of an Amputated Hand at Wrist Level Due to Self-Mutilation: Considerations in Management.

Major self-mutilations include injury to limbs, eyes, or genitals due to various psychiatric illnesses. Limb amputations are grievous injuries that radically decrease the quality of life. Controversy exists as to the advisability of replantation of the self-amputated limb. We report a case of self-amputation of the hand in a 54-year-old gentleman in a fit of psychosis. He underwent replantation of the hand and was given timely psychiatric help. Interdisciplinary management helped in improving the mood of the patient and he cooperated well with the rehabilitation schedule. Recent literature encourages surgeons to replant the limb and treat the mental illness with close observation for warning signs. We conclude that replantation along with early initiation of psychiatry treatment can help the patient overcome psychosis, realize the implications of his actions, and provide the motivation to perform physiotherapy to achieve the optimum outcome possible in the replanted hand.

Assisting in Microsurgery: Operative and Technical Considerations.

Microsurgery is technically challenging, typically requiring a primary surgeon and an assistant to complete several key operative steps. These may include manipulation of fine structures, such as nerves or vessels in preparation for anastomosis; stabilization of the structures; and needle driving. Even seemingly mundane tasks of suture cutting and knot tying require fine coordination between the primary surgeon and assistant in the microsurgical environment. Although prior literature discusses the implementation of microsurgical training centers at academic institutions and residency programs, there is a paucity of work describing the role of the assistant surgeon in a microsurgery operation. In this surgical technique article, the authors discuss the role of the assisting surgeon in microsurgery, with recommendations for trainees and attendings alike.

Does the Functional Status of the Upper Limb Influence Limb Length Discrepancy in a Child with Birth Brachial Plexus Palsy?

Background: Limb length discrepancy (LLD) is a frequent observation in children with birth brachial plexus palsy (BBPP) and a common concern among parents. A common assumption is that the LLD decreases if the child is using the involved limb more. However, there is no literature evidence for this assumption. The present study was conducted to assess the correlation between the functional status of the involved limb and the LLD in children with BBPP. Methods: One hundred consecutive patients (age > 5 years) with unilateral BBPP seen at our institute underwent measurements of limb lengths to assess the LLD. The arm, forearm and hand segments were measured separately. The functional status of the involved limb was assessed using modified House's Scoring system (Scores 0-10). The correlation between limb length and functional status was assessed using the one-way Analysis of Variance (ANOVA) test. Post-hoc analyses were performed as required. Results: A length difference was observed in 98% of the limbs with brachial plexus lesions. The average absolute LLD was 4.6 cm with a standard deviation of 2.5 cm. We found a statistically significant difference in LLD among the patients with a House score of <7 ('Poor function') and 7 and above ('Good function'; p < 0.001) with later indicative of independent use of the involved limb. We found no correlation between age and LLD. More extensive plexus involvement resulted in higher LLD. The maximal relative discrepancy was found in the hand segment of the upper extremity. Conclusions: LLD was seen in most of the patients with BBPP. The functional status of the involved upper limb in BBPP was found to be significantly associated with LLD. Though causation cannot be assumed. We found that children using the involved limb independently tend to have the least LLD. Level of Evidence: Level IV (Therapeutic).

General Population and Surgeon Preferences for Pollicization Versus Toe-To-Thumb Transfer for Reconstruction of Traumatic Thumb Loss in Adults: An International, Multi-Center Survey Study.

PURPOSE: Data objectively comparing outcomes following pollicization versus toe-to-thumb transfer for reconstruction after traumatic thumb amputation in adults remains sparse. Given that this decision is reliant on personal preference, it is important to understand the subjective nature of these preferences, particularly in the context of culture. The purpose of this study was to compare Eastern and Western societal and hand surgeon preferences for pollicization versus toe-to-thumb transfer for traumatic thumb reconstruction. METHODS: Investigators from 6 international locations recruited local hand surgeons and members of the general population. Austria, Germany, the United States, and Spain were grouped as "Western" nations. China and India separately represented "Eastern" nations. Participants completed a questionnaire evaluating their personal preferences for pollicization and toe-to-thumb transfer. The questions posed to the general population and hand surgeons were identical. Demographic data were also collected. RESULTS: When comparing the Western nations, China, and India, there was no difference in personal preferences within the general population for pollicization versus toe-to-thumb transfer. In contrast, most Indian hand surgeons favored toe-to-thumb transfer and most Western surgeons were uncertain about which procedure they would favor. Surgeons had more optimistic expectations regarding postoperative hand function, new thumb sensation, and hand appearance following pollicization than the general population. Similarly, for toe-to-thumb transfer, a greater proportion of surgeons predicted good-to-excellent function, sensation, and appearance. CONCLUSIONS: There was no clear, observed "East" versus "West" difference in the general population's personal preferences for pollicization versus toe-to-thumb transfer among study participants. The members of the general population and hand surgeons had different outcome expectations. CLINICAL RELEVANCE: Understanding how culture influences patient and hand surgeon preferences for pollicization versus toe-to-thumb transfer may help guide future decision-making for traumatic thumb reconstruction.

Single-stage Flexor Hallucis Longus transfer and Gracilis free flap cover for failed Achilles tendon repair with soft tissue defect.

INTRODUCTION: Reconstruction of failed Achilles tendon repair, with infection and loss of overlying skin, is a surgical challenge. This paper aims to deal with the technical considerations and study the outcome of reconstructing such defects by radical debridement and reconstruction with combined Flexor hallucis longus (FHL) transfer and free Gracilis flap cover. MATERIALS AND METHODS: A retrospective study of six patients with failed Achilles tendon repair with overlying skin and soft tissue loss reconstructed by FHL transfer and free Gracilis flap cover performed between January 2017 and August 2020 was conducted. Postoperatively, they were assessed with the Mean Functional Gait Assessment score(MFGA), the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score, the Achilles tendon Total Rupture Score (ATRS), and Modified Vancouver scar scale score (mVSS). RESULTS: All six patients reported a good gait at nine months of follow-up. The MFGA score at six months was 24.8. The mean ankle plantar flexion at nine months follow up was 39.1° . The mean nine-month postoperative AOFAS and ATRS scores were 86.33 ± 2.654 and 88.5 ± 5.54, respectively. At nine months, all the patients could perform a single-leg heel raise on the operated foot. The overall mean mVSS score was 1.41. In about 12 months, the peak forefoot to hindfoot ratio matched the uninjured opposite foot. CONCLUSION: Simultaneous reconstruction of the Achilles tendon with FHL transfer with free Gracilis flap for the coverage of overlying soft tissue loss is a good management option for failed Achilles tendon repair with overlying skin loss.

Parachute Method: A Novel Method to Retrieve a Stuck Degloved Finger.

An entrapped finger is a relatively uncommon domestic injury. When the finger gets stuck proximal to the proximal interphalangeal joint, the resultant distal edema and inappropriate attempts at retrieval can result in circumferential degloving of the skin and injury to the neurovascular structures. We report a technique that can be used in such circumstances. Strategically placed skin sutures are used to get the skin through the constricting ring, and retrieval is aided by a cut finger glove that wraps the finger and can be lubricated. This non-cutting technique is named as the parachute technique since the withdrawn skin sutures look like the strings of the parachute. This technique is valuable when the finger gets stuck in an idli plate, a common South Indian kitchen utensil, where there is difficulty of access to cutting equipment and where inappropriate attempts at retrieval can result in skin injury making further attempts more difficult.

Anatomic Variations of the Musculocutaneous Nerve and Clinical Implications for Restoration of Elbow Flexion.

PURPOSE: The restoration of elbow flexion is of primary importance in the management of patients with brachial plexus injuries. Superior functional outcomes via fascicle transfer from the ulnar and median nerves have resulted in this transfer being considered the mainstay of recovery of elbow flexion in patients with intact C8 and T1 function. An understanding of the anatomy of the musculocutaneous nerve (MCN) and its branching pattern is key while performing these transfers. METHODS: A prospective cohort study was conducted in patients who underwent nerve transfer for the restoration of elbow flexion following a traumatic brachial plexus injury. The anatomic course and branching pattern of the MCN were recorded in eligible cases, both as a line diagram and using intraoperative photographs. RESULTS: One hundred fifty patients underwent nerve transfer for the restoration of elbow flexion following an injury to the brachial plexus. The MCN in 138 patients (92%) was found to pierce the coracobrachialis muscle before emerging lateral to it. One hundred thirty-four patients (89.3%) demonstrated the "classical" anatomy. One hundred fifteen patients (76.6%) had a single primary branch to the biceps, whereas 25 patients (16.6%) demonstrated a discrete motor branch to each head. One hundred thirty-three dissections (88.6%) revealed a single muscular branch to the brachialis arising posteromedially from the MCN, distal to the origin of the branch to the biceps brachii. Notable unreported variations, such as the MCN penetrating the biceps as it descended, multiple brachialis branches, and trifurcation of divisions of the MCN, were documented. CONCLUSIONS: Variations in MCN anatomy are quite common, and even unreported variations can be encountered. CLINICAL RELEVANCE: Exploration of the MCN and its branches for nerve transfers requires knowledge of these anatomic variations and vigilance to prevent inadvertent injuries while dissecting them for nerve transfer surgery.

Role of External Rotation Osteotomy of the Humerus in Patients with Brachial Plexus Injury.

Background: A deficit of external rotation of the shoulder is a common sequelae of brachial plexus injury (BPI). This internally rotated posture of the limb becomes more apparent and functionally limiting once the patient recovers elbow flexion resulting in the hand striking the abdomen on attempted flexion ('tummy flexion'). This precludes hand-to-mouth reach, resulting in an inability to eat with the involved hand. The aim of this study is to present the outcomes of an external rotation osteotomy of the humerus in adult BPI. Methods: All BPI patients who underwent an external rotation osteotomy of the humerus at our institution over a 5-year period from January 2015 to December 2020 were included in this study. Data with regard to the age, gender, type of BPI, time from injury to nerve surgery and from nerve surgery till external rotation osteotomy, degree of pre- and postoperative external rotation, time to union, patient satisfaction and complications were recorded. Results: The study included 19 patients (18 men and one woman) with an average age of 30 years (range 20-58). The average time interval from the injury to the nerve surgery was 3.8 months, and between the nerve surgery and the external rotation osteotomy was 29.5 months. No patient had any preoperative external rotation and all attained a resting posture of 15°-20° of external rotation, were able to reach the mid-line of the body, and none complained of loss of internal rotation. There was an implant failure in one patient that was managed with splinting till union and removal of implants later. Conclusions: External rotation osteotomy of the humerus is a simple and effective procedure to place the limb in a better aesthetic and functional position. Level of Evidence: Level IV (Therapeutic).

Brachioradialis to Extensor Carpi Ulnaris Transfer - An Additional Transfer to Prevent Radial Deviation Deformity of the Wrist following Tendon Transfers for Posterior Interosseous Nerve Palsy.

The usual recommendation in posterior interosseous nerve (PIN) palsy is to use the flexor carpi radialis instead of the flexor carpi ulnaris (FCU) for restoration of digital extension. The use of FCU takes away the only remaining ulnar deviator of the wrist. Although preserving the FCU prevents severe radial deviation deformity, we found that some patients still develop a radial deviation deformity, especially during wrist extension. We have used a brachioradialis (BR) to extensor carpi ulnaris (ECU) transfer to prevent the development of a radial deviation deformity and find that it restores the normal radio-ulnar balance of the wrist by providing a dynamic ulnar stabiliser. It is a simple addition to the standard two tendon transfers for PIN palsy with minimal donor morbidity. We have used this triple transfer for PIN palsy in seven patients with satisfactory results and no complications. Level of Evidence: Level V (Therapeutic).

Restoration of Hand Function in Isolated Lower Brachial Plexus Injury with Brachioradialis to Flexor Pollicis Longus and Biceps to Flexor Digitorum Profundus Transfer.

Background: Isolated lower (C8T1) brachial plexus injury (BPI) is uncommon and the aim of treatment is to achieve a satisfactory grasp enabling the use of the hand for daily activities. The aim of this study is to report the outcomes of the transfer of brachioradialis (BR) to flexor pollicis longus (FPL) and biceps to the flexor digitorum profundus (FDP) for an isolated lower BPI. Methods: This is a retrospective study of all patients with an isolated lower BPI who underwent a BR to FPL and biceps to FDP transfer for restoration of digital flexion over a 1-year period from May 2019 to June 2020. Patient demographic and injury data were collected at the presentation. Outcomes data included the ability to grasp and perform activities of daily living and DASH score. Results: The study included three patients (all men) with an average age of 30.3 years. All sustained an isolated lower BPI following a road traffic accident and tendon transfers were performed at a mean of 9.3 months after the initial injury. At a mean of 1-year follow-up, all three recovered grade M4 motor power of digital flexion, achieved good grasp function with pulp-to-palm distance of <1 cm. All are able to use the hand for independent as well as bimanual activities. The individual DASH scores were 36, 30 and 30. Conclusions: BR to FPL for thumb flexion and biceps to FDP using fascia lata graft to restore finger flexion is simple and effective surgeries in patients with isolated lower BPI. Level of Evidence: Level V (Therapeutic).

First Successful Separation of Craniopagus Twins in India-Plastic Surgical Considerations.

Separation of total vertical craniopagus with shared venous sinuses poses multiple challenges. Provision of soft-tissue cover to the exposed brains at the time of total separation is one of them, due to the large size of the defect and paucity of local tissues. Staged separation of twins is advised with partial venous and parenchymal disconnection in the first stage and total separation in the second stage. Tissue expanders are inserted in the first stage, and second stage planned to coincide with the period of adequate expansion. In the child being reported, emergency second stage was done due to the deteriorating general condition of the children. Left with inadequate expanded skin, the critical defect in a twin was managed with bilateral trapezius myocutaneous flaps. High ionotropic support of the postoperative period resulted in superficial necrosis of the flap, which was managed by debridement, allograft application and autograft later. Both twins had well-healed wounds by 3 months.
