Clinical evidence of the association between radial longitudinal deficiency and radial polydactyly: a case series.

Radial longitudinal deficiency (RLD) is commonly associated with thumb hypoplasia. The association between RLD and radial polydactyly (RP) is uncommon, but case reports or case series have been reported. We report our experience of managing patients with this association. A total of 97 patients with RLD were seen in our department, of which six were children with concomitant RLD and RP. Four children had both RLD and RP in the same limb; of them, three also had RLD in the contralateral limb. The mean age at presentation was 11.6 months. Awareness of this association alerts the clinician to look for RLD in the presence of RP and vice versa. This case series supports recent experimental and clinical evidence that RP and RLD may be part of the same developmental spectrum. Further studies may guide its inclusion as a possible new category in the Oberg-Manske-Tonkin (OMT) classification of congenital upper-limb anomalies.Level of evidence: IV.

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.

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.

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.

Diabetic Hand Infections: Factors at Presentation Influencing Amputation and Number of Surgical Procedures.

Background Diabetic hand infections are associated with significant morbidity and disability. Amputations cause permanent disability, and multiple surgical procedures lead to morbidity. Diabetic foot infections have been well-studied but literature on hand infections is limited. We undertook a retrospective study of patients with diabetic hand infections operated at our center to study the factors at presentation with significant association with amputation and number of surgical procedures. Patients and Methods Demographic data of 51 patients was collected. The six parameters, namely, duration of diabetes, "onset of symptoms to presentation" interval, presence of comorbidities, HbA1c level, random blood sugar (RBS) levels at admission, and culture characteristics were selected for statistical analysis to find a relationship with the two outcome variables: number of procedures done and need for amputation. Results On bivariate analysis, Gram-negative infection was found to have a significant relationship with the need for multiple of procedures ( p = 0 . 014). The mean difference between the "onset of symptoms to presentation" interval between the amputation/non-amputation groups (2.9 days, p = 0 . 04) and the multiple procedures/non-multiple procedure groups (4.4 days, p = 0 . 02) was found to be statistically significant. Presence of comorbidities, long duration of diabetes, HbA1c, and RBS levels at admission did not show any statistically significant association with the two outcome variables studied. Conclusion In the present study, we found that infection with Gram-negative organisms is significantly related to the need for multiple surgical procedures. A delay in presentation can influence the risk of amputation as well as multiple procedures. Institution of early appropriate care is important to get a good outcome.

Bleeding Post Constriction Ring Release Surgery Causing Lower Limb Ischemia in an Infant with Undetected Hemophilia B.

Bleeding in the immediate postoperative period causing compromised limb circulation is an alarming complication. It is known to occur in coagulation disorders like hemophilia. When such complications happen in a child with no previous history of bleeding problems, one has to have a low threshold for suspecting a coagulation disorder. Repeated diffuse bleeding in the whole of the surgical wound with no specific bleeders must raise the suspicion and appropriate laboratory tests must immediately be ordered. Bleeding in coagulation disorders can stop only with supplementation of the appropriate missing clotting factor. Early diagnosis is important to avoid excess morbidity. We are reporting a 6-month-old child who underwent surgery for constriction ring syndrome in the limbs with Z-plasty please replace with and developed impending limb ischemia due to bleeding in the immediate postoperative period. The article emphasizes the need to think of the possibility while encountering recurrent bleeding in the postoperative period.

Nonvascularized Free Toe Phalangeal Transfers in Congenital Hand Differences: Radiological, Functional, and Patient/Parent-Reported Outcomes.

PURPOSE: To evaluate radiologically, functionally and by patient-reported outcome measures, nonvascularized free toe phalangeal transfer (NVFTT) in the reconstruction of congenital short fingers with redundant soft tissue. METHODS: Nineteen children who underwent NVFTT in 40 digits were studied. Of these, 13 patients with a mean follow-up of 5.2 years were assessed radiologically for epiphyseal patency, growth, growth rate, and length comparison with the contralateral toe. Eight children were available for an in-person follow-up. In these patients, we measured the pinch strength and range of motion. The Pediatric Outcomes Data Collection Instrument; the upper extremity, depression, anxiety, pain interference, and peer relationships domains of the Patient-Reported Outcomes Measurement Information Systems; and the aesthetic component of the Michigan Hand Questionnaire were used for the assessment of psychosocial impact. RESULTS: An open epiphysis was found in 24 of 31 grafts. Among these, 20 of 21 grafts were in 9 children younger than 18 months and 4 of 10 grafts were in children older than 18 months at the time of operation. The mean growth was 3.4 mm. The mean growth rate was 1.3 mm/y. Length was 71.8% of the contralateral phalanx. The key pinch strength was 1.3 kg (2.6 kg on the normal side). The mean range of motion at the metacarpophalangeal joint was -4° to 65° flexion. Two proximal interphalangeal joints were stiff and 2 had range of motion of 0° to 30°. Children evaluated with Pediatric Outcomes Data Collection Instrument had high mean scores in all domains. The Patient-Reported Outcomes Measurement Information Systems scores were low for the upper-extremity domain. On the aesthetic component of the Michigan Hand Questionnaire, children gave higher scores than parents. Donor toes, though short, did not cause a functional disability. CONCLUSIONS: NVFTT reliably provides length, stability, and movement in short fingers with redundant soft tissue. In addition to good radiological and clinical outcomes, the patient-reported outcome measures support performing NVFTT in children. Surgery before 18 months, extraperiosteal harvests of grafts, and avoidance of tight skin closures are important. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Technical considerations and outcome of free functioning gracilis muscle transfer for finger flexion in patients with Volkmann's Ischemic Contracture.

INTRODUCTION: Severe Volkmann's Ischemic Contracture (VIC) is a reconstructive challenge for the surgeon because of the loss of entire flexor muscle mass and lack of powerful wrist extensors for restoration of finger flexion. In such cases, free functioning muscle transfer (FFMT) using gracilis is our choice. We herein summarize the technical considerations to achieve a successful outcome and report functional outcome achieved in our series. PATIENTS AND METHOD: Between 2007-2018, 22 patients of VIC underwent gracilis FFMT for restoration of finger flexion. FFMT was done as a second stage following an initial stage of neurolysis/excision of fibrotic flexor muscles/contracture release/flap cover in these patients. Cases were retrospectively reviewed and their functional outcome at a minimum of one-year follow up was analyzed. Follow-up duration ranged from 2-13 years (average-4 years). At the final follow up, the motor and sensory recovery was evaluated using the Medical Research Council Grading and their function using Disabilities of the Arm, Shoulder, and Hand (DASH) score. RESULTS: The average age at surgery ranged from 3-45 years (average-18.4 years). All the transferred muscles survived. Secondary procedures to further improve the hand function were done in nine patients. The motor recovery for finger flexion was graded as M2 in two, M3 in nine and M4 in 11 cases. These 20/22 patients who recovered M3/M4 finger flexion expressed high satisfaction with the operation while other two also felt that they were better after the surgery. DASH score was available for 13 patients and it averaged 13.21 (Range-1.8-34.5). Grip strength was available for 10/22 patients and it averaged 10.5 kg (range-0-21kg) amounting to 24% of the normal side. The sensory recovery was graded as S4 in two, S3 in 17 and S2 in three cases. CONCLUSION: Gracilis FFMT is a reliable option for restoration of finger flexion in patients with severe VIC. Outcome is better when done after an early preliminary stage of excision of fibrosed muscles and neurolysis which allows recovery of intrinsic function and sensation. FFMT is best carried out 3-6 months after the first stage with supple skin and good passive range of movement in the fingers.

Cross-Hand Replantation.

Combined major injury to both upper extremities, in which one hand is amputated and structurally intact but not replantable, and the other hand is unsalvageable, is a rare setting in which cross-hand replantation may be considered. We report a case of an emergency cross-hand replantation performed at the wrist level. In our case, insertions of the wrist flexor and extensor tendons at the second and third metacarpal bases were retained at the recipient, allowing for early active wrist motion and finger motion by tenodesis. Fascicle-specific nerve coaptations were performed. The patient achieved satisfactory functional results, allowing him independence with daily living activities and return to gainful employment. At the time of telemedicine follow-up at 5 years, he was employed full-time, reported no difficulty or mild difficulty with most daily activities, and preferred the use of his replanted hand over a contralateral prosthesis.

Reconstruction of a Monodactylous Hand with Microsurgical Free Foot-to-Hand Transfer in Split-Hand/Split-Foot Malformation with Tibial Aplasia.

Split-hand/split-foot malformation with long bone deficiency (SHLFD syndrome) is a rare congenital disorder, which may be sporadic or autosomal dominant with incomplete penetrance. When complete tibial aplasia is seen, the mainstay of treatment is amputation and lower limb prosthesis. This rare constellation of congenital differences presents an opportunity for microsurgical free tissue transfer using the principle of "spare parts" to improve the functionality of the hand. We present a rare case of split-hand/split-foot malformation with a monodactylous right hand and complete tibial aplasia, treated with microsurgical free foot-to-hand transfer at the time of lower limb amputation, reconstructing key pinch. At the latest 8 months follow-up, the patient had no pain, active key pinch, and ambulated independently with prostheses. He was able to use his right hand independently for a number of daily activities, such as stacking blocks, drinking from a cup, and playing with toys.

Pedicled Split Hypogastric Flap (Superficial Inferior Epigastric Artery flap): A New Technique for Coverage of Nonadjacent Defects in the Hand.

Flap coverage of soft tissue defects on both surfaces of the hand or of nonadjacent defects in the hand is a challenge. Two flaps are needed or if a single flap is used, the intervening normal area or part of the flap must be deepithelialized or the flap tunneled under the normal bridge segment. We are presenting a new technique whereby the hypogastric flap based on the superficial inferior epigastric artery is split into 2 components for the coverage of such defects. The hypogastric flap is separated into a cutaneous component and an adipofascial component at the level of Scarpa fascia. The flaps are separated almost to the base to increase mobility. Now it can be used to cover 2 defects separated by 5 to 7 cm or for defects in the dorsum and the palm. We have used it in 3 patients, in 2 for the coverage of palmar and dorsal aspect of the hand and in one for the coverage of nonadjacent defects on the dorsum of the hand and distal forearm after postburn contracture release. We achieved good results with no flap-related complications.

Initial Assessment, Debridement, and Decision Making in the Salvage of Severely Injured Lower Extremity.

An open fracture with extensive skin and soft tissue loss is considered as a severely injured lower extremity. Advances in rapid transport, resuscitation, skeletal fixation, and microsurgical techniques to cover large soft tissue and bone defects have made possible the salvage of these severely injured limbs. Salvage exercise is skill and resource intensive and could take a long time frame. The goal of management is to obtain painless independent weight bearing walking in a time frame and cost that the patient can afford. Decisions taken and the quality of care provided on day 1 determine the ultimate success. Inappropriate decisions and treatment lead to increased morbidity and secondary amputation. Infection is the commonest complication. Limb salvage scores are helpful to predict salvage and guide the sequence of treatment. Once the decision is taken for salvage, debridement, early skeletal fixation, and soft tissue cover are the key to success.
